Answer:
use the Pythagorean theorem
Step-by-step explanation:
The slant height is the hypotenuse of a right triangle whose legs are the height of the pyramid and the distance from the edge of the base to the center of the pyramid (where the height segment reaches the base).
For h = pyramid height, b = base edge length, s = slant height, the Pythagorean theorem tells you ...
h² + (b/2)² = s²
Solving for h gives ...
h = √(s² -(b/2)²) . . . . . the height of the pyramid

Which of these expressions shows a correct way to set up the slope formula for the line that passes through the points (3, 7) and (5, 7)?
A) 5 - 3/ 7 - 7
B) 3 - 5/ 7 - 7
C) 7 - 5/ 7 - 3
D) 7 - 7/ 5 - 3
The slope formula for the line that passes through the points (3, 7) and (5, 7) is (7-7)/ (5-3).
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
We have points (3, 7) and (5, 7).
So, the slope of line passes through the given points
= ( 7 - 7) / (5-3)
= 0- 2
= 0
Thus, the slope formula is (7-7)/ (5-3).

On a weekend class gathering at a museum, a teacher brings $50 to pay for museum
admission. She buys an adult ticket for $3.50 and 13 student tickets. Three students arrive late
so she buys 3 more student tickets. She has $18.50 left. Which equation can you use to find the
cost of a student ticket?
a. 13x + 3x = 50 - 18.50 c. 13x + 3.50 +3x = 50
b. 13x + 3.50 + 3x + 18.50 = 50 d. 3x = 3.50 + 13x
The equation used to find the cost of student ticket is:
[tex]13x + 3.50 + 3x + 18.50 = 50[/tex]
Solution:
Given that,
A teacher brings $50 to pay for museum admission
She buys an adult ticket for $3.50 and 13 student tickets
Cost of adult ticket = $ 3.50
Let "x" be the cost of each student ticket
Three students arrive late so she buys 3 more student tickets
She has $18.50 left
The equation used to find the cost of student ticket is:
Cost of adult ticket + 13 student tickets x cost of each student ticket + 3 student ticket x cost of each student ticket = 50 - 18.50
[tex]3.50 + 13x + 3x = 50-18.50\\\\13x + 3.50 + 3x + 18.50 = 50[/tex]
Thus the above equation is used
Our car has a 15-gallon gas tank. A lower grade of gasoline costs $2.96 per gallon. The premium grade gasoline costs
$3.15 per gallon. There are three gallons left in your gas tank. What is the difference in the cost of filling your tank between the two grades
of gasoline?
a) $2.05
b) 52.28
c) $35.52
d) $44.40
Answer:
The correct option is b.) $2.28
Step-by-step explanation:
i) the gas tank is of 15 gallons
ii) there are three gallons left in the gas tank
iii) therefore the tank has to be filled with 15 - 3 = 12 gallons
iv) lower grade of gasoline costs $2.96 per gallon
v) the upper grade of gasoline costs $3.15 per gallon
vi) the cost of filling the tank with the lower grade gasoline
= 12 [tex]\times[/tex] 2.96 = $35.52.
vii) the cost of filling the tank with the lower grade gasoline
= 12 [tex]\times[/tex] 3.15 = $37.80
viii) therefore the difference in the cost of filling your tank between the two grades
= $37.80 - $35.52 = $2.28
Therefore the correct option is b.) $2.28
Final answer:
The difference in the cost of filling the 15-gallon gas tank between the two grades of gasoline is $2.28.
Explanation:
Firstly, let's calculate how many gallons are needed to fill the car's tank completely, since it currently has 3 gallons left in a 15-gallon tank. This means the car requires 15 - 3 = 12 gallons of gasoline to be filled up.
Next, we calculate the cost to fill up the car with the lower grade gasoline that costs $2.96 per gallon. The cost for 12 gallons would be 12 x $2.96 = $35.52.
Then, we calculate the cost to fill up the car with the premium gasoline that costs $3.15 per gallon. The cost for 12 gallons would be 12 x $3.15 = $37.80.
Finally, to find the difference in cost between the two grades of gasoline, we subtract the lower cost from the higher cost: $37.80 - $35.52 = $2.28. Hence, the difference in cost is $2.28, so the correct answer is option (b).

Find the equation of a straight line that has a perpendicular bisector of AB.
A = (2,6) B = (5, -2)
Answer:
So the line that is a perpendicular bisector of AB is [tex]y=\frac{3}{8}x+\frac{11}{16}[/tex].
Step-by-step explanation:
If we are looking for a line such that is is perpendicular bisector of AB, then we first need to find the midpoint of AB.
The midpoint of AB is going to be the "average" point.
What I mean by this, to find the x-coordinate of the midpoint we need to average our x-coordinates of our endpoints and we also need to do the same for the y-coordinate part.
Let's begin this.
The average of the x-coordinates of the endpoints are:
[tex]\frac{2+5}{2}=\frac{7}{2}[/tex]
The average of the y-coordinates of the endpoints are:
[tex]\frac{6+(-2)}{2}=\frac{4}{2}=2[/tex]
This concludes the midpoint of AB is [tex](\frac{7}{2},2)[/tex].
Now we also need to calculate the slope of [tex]AB[/tex] so we can find the slope of the line perpendicular to it.
To do this we could use [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. Without using the formula directly, I like to line the points up vertically and subtract. I then put the 2nd difference over the first difference. Like so,
[tex](5,-2)[/tex]
-[tex](2,6)[/tex]
----------------------
[tex]3 , -8[/tex]
So the slope is [tex]\frac{-8}{3}[/tex].
The line that is perpendicular to the line AB will have an opposite reciprocal slope.
So the line we are looking for has slope [tex]\frac{3}{8}[/tex].
So we are looking for a line going through the midpoint [tex](\frac{7}{2},2)[/tex] and has slope [tex]\frac{3}{8}[/tex].
A line in slope-intercept form is [tex]y=mx+b[/tex].
We know [tex]m=\frac{3}{8}{/tex] and we know a point [tex](x,y)=(\frac{7}{2},2)[/tex]. We could plug this in to find [tex]b[/tex].
Let's do that now.
[tex]2=\frac{3}{8}(\frac{7}{2})+b[/tex]
Simplify:
[tex]2=\frac{21}{16}+b[/tex]
Subtract 21/16 on both sides:
[tex]2-\frac{21}{16}=b[/tex]
Find a common denominator:
[tex]\frac{32}{16}-\frac{21}{16}[/tex]
[tex]\frac{11}{16}[/tex]
So the line that is a perpendicular bisector of AB is [tex]y=\frac{3}{8}x+\frac{11}{16}[/tex]. This is so because the line we found will be perpendicular to AB while also cutting AB into two equal halves.
Write an equation in Slope-intercept form for the line that is perpendicular to the line y = 2x - 5 that passes through the given point (4,-2).
Answer:
y = (-1/2)x
Step-by-step explanation:
The slope of the given line is 2, the perpendicular line wil have a reciprocal slope given by -1/2 (add a minus sign, move the slope to the denominator).
So all that's left to calculate is the offset b of a line
y = -1/2 x + b
such that it passes through (4,-2). Filling in that point gives:
-2 = -1/2*4 + b
so b = 0!
y = -1/2x is the answer
Line perpendicular to y = 2x - 5 is y = (-1/2)x.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
We know perpendicular lines have slopes that are negative reciprocal of each other.
The given line y = 2x - 5, has a slope of 2.
So, the given line will have a slope of (-1/2) passing through point (4,-2).
∴ - 2 = (-1/2)(4) + b.
- 2 = - 2 + b.
b = 0.
∴ y = (-1/2)x is our required line.

Write a system of equations to describe the situation below. Sparkles the Clown makes balloon animals for children at birthday parties. At Jenny’s party, she made 2 balloon poodles and 2 balloon giraffes, which used a total of 12 balloons. For Roger’s party, she used 27 balloons to make 4 balloon poodles and 5 balloon giraffes. How many balloons does each animal require?
Each animal require 3 balloons.
Step-by-step explanation:
Let 'x' be the number of balloon poodles.
Let 'y' be the number of balloon giraffes.
2x+2y = 12 ---------(1)4x+5y = 27 ---------(2)Multiply eqn (1) by 2 and subtract eqn(2) from eqn(1),
4x+4y = 24
(-) 4x+5y = 27
-y = -3
⇒ y=3
⇒ Number of balloon giraffes = 3
Substitute y=3 in eqn(1)
⇒ 2x+2(3) = 12
⇒ 2x+6=12
⇒ x = 6/2
⇒ x = 3
⇒ Number of balloon poodles = 3

What type of triangle can a right triangle be?
Answer:
it could be a isosceles triangle.
Step-by-step explanation:
A right triangle can also be an isosceles triangle.
Final answer:
A right triangle, which always has a 90-degree angle, can be either Scalene if all sides are different lengths, or Isosceles if two sides are equal. The classification depends on the lengths of the sides. Additionally, right triangles are fundamental to the application of the Pythagorean theorem.
Explanation:
A right triangle is a type of triangle that has one angle measuring exactly 90 degrees. Despite always having this right angle, right triangles can vary in the lengths of their other sides and the measures of their other angles. So, a right triangle can also be classified based on its side lengths:
If all three sides of a right triangle have different lengths, it is a Scalene right triangle.If two sides of a right triangle (the legs) are of equal length, it is known as an Isosceles right triangle, and this also implies that the two non-right angles are equal, each being 45 degrees.Therefore, the type of right triangle depends on the specific side lengths and can be either Scalene or Isosceles. The understanding of right triangles also extends to concepts such as the Pythagorean theorem, which relates the lengths of the sides of a right triangle, stating that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

Solve the equation 0.5p-3.45=-1.2
Answer:
4.5
Step-by-step explanation:
The equation above is such that we find the value of p. Therefore, it is calculated thus:
0.5p - 3.45 = -1.2
Add 3.45 to both sides of the equation
0.5p - 3.45 + 3.45 = -1.2 + 3.45
0.5p = 2.25
Divide both sides by 0.5
0.5p/ 0.5 = 2.25/0.5
p = 4.5
Answer: The answer is 4.5
Step-by-step explanation:
0.5p - 3.45 = -1.2
So basically, you take everything on the left of the equal sign (0.5p-3.45) then since the sign is telling you to subtract, you use the inverse operation, so you would add 0.5 to the 3.45 and to the -1.2. So when you add the 0.5 to the 3.45, it cancels out, and when you add it to the -1.2, you should get 2.25. Then now that your done adding, your expression should be: 0.5p = 2.25. Then, now that you have 0.5p = 2.25, and there is no sign, multiplication is expected, but since were using the inverse operation, were dividing. So, 0.5p divided by 0.5 cancels out, and then you divide the 2.25 by 0.5 and you should get 4.5 after dividing. So, your final answer should be p = 4.5.

y = 3x +19
y = 5x +33
Solve this system of equation by substitution
Answer:
( -7, -2)
Step-by-step explanation:
3x + 19 = 5x + 33
x = -7
y= 3x ( - 7) + 19
y= -2
(x, y) = (-7,-2)
The x and y value is -7 and -2.
Given that,
The equations are y = 3x +19 and y = 5x +33.We need to find the value of x and y.Based on the above information, the calculation is as follows:
3x + 19 = 5x + 33
3x - 5x = 33 - 19
-2x = 14
x = -7
Now put the value of x in any of the above equation
So,
y = 3x + 19
= 3(-7) + 19
= -21 + 19
= -2
Therefore we can conclude that the x and y value is -7 and -2.

The probability of taking a red bead first and a white bead second is:
P(red, white) = (7/11) (4/10)
P(red, white) = 14/55
The probability of taking a white bead first and a red bead second is:
P(white, red) = (4/11) (7/10)
P(white, red) = 14/55
