Answer:
PQ = 13 cm
Step-by-step explanation:
You need to use the Pythagorean Theorem twice.
On the base of the cuboid, mark the point opposite P, point A. Point A is vertically below point Q. Now draw a segment from point P to point A.
The distance from point P to point A can be found using the Pythagorean Theorem.
(3 cm)^2 + (4 cm)^2 = (PA)^2
9 cm^2 + 16 cm^2 = (PA)^2
25 cm^2 = (PA)^2
PA = 5 cm
Segment PA is a side of triangle PAQ. Angle PAQ is a right angle. Sides PA and AQ are legs of the right triangle, and side PQ is the hypotenuse. Now we use the Pythagorean Theorem again.
(PA)^2 + (AQ)^2 = (PQ)^2
(5 cm)^2 + (12 cm)^2 = (PQ)^2
25 cm^2 + 144 cm^2 = (PQ)^2
169 cm^2 = (PQ)^2
PQ = 13 cm

You are in charge of buying hamburgers and chicken for a party. The hamburgers cost $2 per pound and the chicken costs $3 per pound. You have $60 to spend. Write and solve a linear equation to find how much chicken you can afford to buy if you buy 12
pounds of hamburgers.
Linear equation is 2x + 3y = 60
Chicken that can be afforded is 48 pounds.
Step-by-step explanation:
Step 1:
Given details are cost of hamburgers per pound = $2 and cost of chicken per pound = $3, total amount for spending = $60
Step 2:
Form equation from given data.
Let x be number of hamburgers bought and y be number of chicken that can be bought.
⇒ 2x + 3y = 60
Step 3:
Given that 12 pounds of hamburgers can be bought. Then 2x = 12. Substitute in equation to find pounds of chicken
⇒ 12 + 3y = 60
⇒ 3y = 60 - 12 = 48
⇒ 3y = 48 pounds or y = 16 (number of chicken that can be bought)

Answer:
A: 900 yards
Step-by-step explanation:
im sure... i had the same test question and got it right! pls give me brainliest
Answer:
900 sq. yd.
Step-by-step explanation:
So, we know that the baseball diamond is a square, so we use the equation of a square, A = [tex]a^{2}[/tex]
Since all sides of a square are equal, each is always gonna be 30 yards. So we substitute a for 30
A = [tex]a^{2}[/tex]
A = [tex]30^{2}[/tex]
A = 900 sq. yd.
Which gives you the area of the diamond as 900 sq. yd.
Two angles are complementary three times the measure of one of the angles is 10° more than the measure of the other angle. find the difference between the measure of the larger angle in the smaller angle
Answer:
The difference is 40,
Step-by-step explanation:
Complementary angles , x+y =90
so we know angle 1, we call it 3x and angle 2 we call it y= 3x+10
so 3x +10= 90-x
4x=100
x=25
angle 1= 3(25) - 10
y= 65
65-25= 40
Answer:
40°
Step-by-step explanation:
Let x represent one of the angles, and y represent the other one. Then we have ...
x + y = 90
3x = y +10
Substituting for y in the first equation, we have ...
x + (3x -10) = 90
4x = 100
x = 25
y = 3(25) -10 = 65
The difference between the angles is ...
y -x = 65 -25 = 40 . . . . degrees
The difference between the angle measures is 40 degrees.

The height of a triangle is 5 m less than it’s base. The area of the triangle is 42 m^2 what is the length of the base
Answer:
12 meters
Step-by-step explanation:
Let b = base
then
b-5 = altitude
since we know that the area for any triangle is
(1/2)bh
where
b is base
h is height or altitude
(1/2)b(b-5) = 42
b(b-5) = 84
b^2-5b = 84
b^2-5b-84 = 0
(b-12)(b+7) = 0
b = {12, -7}
toss out the negative solution leaving:
b = 12 meters
Here is the set up:
A = (bh)/2
42 = [b • (b - 5)]/2
This is all you need. Solve the equation for b to find your answer.
Find the volume of a cube where the length of each side is 6 centimeters.
Answer:
V = 6³ = 216 cm³
The volume of this cube is 216 cm³.
The correct answer is [tex]\( \boxed{216 \text{ cm}^3} \).[/tex]
The volume of a cube is calculated by raising the length of one side to the power of three, or in other words, by multiplying the length of one side by itself three times. Given that the length of each side of the cube is 6 centimeters, the volume [tex]\( V \)[/tex] can be calculated as follows:
[tex]\[ V = a^3 \][/tex]
where [tex]\( a \)[/tex] is the length of a side of the cube. Substituting the given value:
[tex]\[ V = 6^3 \][/tex]
[tex]\[ V = 6 \times 6 \times 6 \][/tex]
[tex]\[ V = 216 \][/tex]
Therefore, the volume of the cube is [tex]\( 216 \)[/tex] cubic centimeters.

Round the weight of the sweet potato chips to the nearest tenth of an ounce. 3.705
Answer:
Step-by-step explanation:
3.705 rounded to the nearest tenth of an oz = 3.7 <==
The weight of the sweet potato chips, when rounded to the nearest tenth, is 3.7 ounces.
Explanation:To round the weight of the sweet potato chips to the nearest tenth of an ounce, we look at the number in the hundredths place.
Since the weight is 3.705, and the number in the hundredths place is 0.005, we apply a basic rounding rule: if the number in the hundredths place is 5 or more, we round up the number in the tenths place.
Here, that means we round up '7' to '8'. Thus, when rounded to the nearest tenth of an ounce, the weight of the sweet potato chips is 3.7 ounces.

There is a mountain with 30 bat caves in a row that contain 340 bats in all. Any 7 caves in a row contain exactly 77 bats. Suppose the first cave has 7 times more bats than the last caves. How many bats in the 29th cave?
Answer:
The 29th cave has 28 bats.
Step-by-step explanation:
It is given that any 7 caves in a row contain 77 bats.
So, out of the 30 caves, let us start counting from the second cave till the 29th cave(counting 28 caves).
7 times 4 gives us 28, which has [tex]77\times4=308[/tex] bats. We have not counted the first and last cave.
Let the number of bats in the last cave be [tex]x[/tex], then according to the question:
[tex]7x+x=340-308=32[/tex](First cave has 7 times more bats than the last cave)
Hence, [tex]x=4[/tex](number of bats in the 30th cave)
Now we shall again count, but this time from the first cave, leaving out the last 2 caves. So the total number of bats in the first 28 caves is 308 and 32 in the last 2 caves.
So, the number of bats in the 29th cave = 32 - 4 = 28
Three more than the quotient of a number and 5 is equal to 9
Answer:
The number is 30.
Step-by-step explanation:
x/5+3=9
x/5=9-3
x/5=6
x=6*5
x=30
The number is 30.
Explanation:The given question is a mathematical equation.
Let's define the number as 'x'. According to the given equation, the quotient of the number and 5, which is x/5, when three is added to it, should be equal to 9. Mathematically, we can write this as:
x/5 + 3 = 9
To solve for x, we need to isolate x on one side of the equation. We can do this by subtracting 3 from both sides of the equation:
x/5 = 9 - 3
x/5 = 6
To get rid of the fraction, we can multiply both sides of the equation by 5:
x = 6 * 5
x = 30
Therefore, the number is 30.
