WHICH STATEMENT IS TRUE ABOUT THE PRODUCT OF 5/12 X 7
Final answer:
The product of 5/12 multiplied by 7 is equal to 35/12.
Explanation:
The product of 5/12 multiplied by 7 is equal to 35/12. To multiply fractions, you multiply the numerators together to get the new numerator, and multiply the denominators together to get the new denominator. Therefore, (5/12) x 7 = (5 x 7) / (12 x 1) = 35/12.

Put x=4
2(4)+2:SQ=2:1
10:SQ=2:1
Therefore |SQ|=5
2x-7y=12 for y answer please
Answer: If you want mx + b= y form and you want the y intercept, then the answer would be 2x/7 - 12/7 = y. The y intercept is b, so it is 12/7.
Step-by-step explanation: 2x - 7y = 12
Move -7y to the other side: 2x= 12 + 7y
Subtract 12 to the left side: 2x - 12 = 7y
Then divide 7 into everything: 2x/7 - 12/7 = 7y/7
The 7s in the right side cancel out, so the equation is now: 2x/7 - 12/7 = y
The y intercept is b, which is the second term in the equation, so the
Y Equals : 12/7

y=(x-2)^2+4
y=-(x+2)^2+4
y=-(x-2)^2+4
Answer:
y=(x-2)^2+4
Step-by-step explanation:
The quadratic function that represents the parabola is y = - (x - 4)² + 4.
What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
From the graph of the function, the parabola intersects the x-axis
at 0 and 4, and we also know when a parabola opens downwards the equation is negative.
So, The required equation is y = - (x - 0)(x - 4).
y = - (x² - 4x).
y = - {x² - 4x + 4 - 4}.
y = - { (x - 2)² - 4}.
y = - (x - 4)² + 4.

To solve the system of equations, we can use the matrix tool. The solution to the system of equations is (1, 1.5) as an ordered pair.
To solve the system of equations using matrices, you can represent the coefficients and constants as matrices and then use matrix operations. The system of equations can be represented in matrix form as:
[A] [X] = [B],
Where:
[A] is the coefficient matrix,
[X] is the variable matrix (containing x and y),
[B] is the constant matrix.
For the given system of equations:
4x + y = 0
8x - y = 6
The coefficient matrix [A], variable matrix [X], and constant matrix [B] are:
[A] = [[4, 1],
[8, -1]]
[B] = [[0],
[6]]
Now, to solve for [X], you can use matrix multiplication:
[A] [X] = [B]
[X] = [A]⁻¹ [B]
First, calculate the inverse of [A]:
[A]⁻¹ = [[-1/12, -1/12],
[1/4, 1/4]]
Now, multiply [A]⁻¹ by [B]:
[X] = [[-1/12, -1/12],
[1/4, 1/4]] [0, 6]
[tex][X] = [(-1/12 \times 0 + -1/12 \times 6),[/tex]
[tex](1/4 \times 0 + 1/4 \times 6)][/tex]
Simplify:
[X] = [-(-1), 1.5)]
[X] = [1, 1.5]
So, the solution to the system of equations is (1, 1.5) as an ordered pair.

A degree may seem like a very small unit but an error of one degree in measuring an angle may be very significant. For example, suppose a laser beam directed toward the visible center of the moon misses its assigned target by the amounts specified below. How far is it (in miles) from its assigned target in each case? (Use 234,000 miles as the distance from the surface of the earth to the surface of the moon.)
a: 1 degree
b: 30” (that’s 0 degree 0’ 30”)
To calculate the distance by which a laser beam misses its target on the moon due to an angular error, one can use the tangent function with the Earth-moon distance. For an error of 1 degree, it would miss by approximately 4,080 miles, and for an error of 30 arcseconds, by about 34 miles.
To find out how far a laser beam directed toward the center of the moon misses its target by 1 degree, we can use a simple trigonometric calculation. Since we are dealing with a right-angled triangle with the Earth-moon distance as one leg (the adjacent leg in this case), and we want to find the opposite leg which represents the distance on the moon's surface from the intended target, we can use the tangent function.
For an error of 1 degree:
Convert the degree to radians, because trigonometric functions in calculators usually use radians. There are π radians in 180 degrees, so 1 degree is (π/180) radians.
Use the formula distance = tangent of the angle in radians × Earth-moon distance. So distance = tan(1° × (π/180)) × 234,000 miles.
Calculate the tangent of 1° in radians (approximately 0.01745) and multiply by 234,000 miles.
The result is approximately 4,080 miles.
For an error of 30 arcseconds (30″):
There are 60 arcseconds in 1 arcminute and 60 arcminutes in 1 degree, hence 30 arcseconds is 30/60/60 degrees, which equals 1/120 degrees.
Convert 1/120 degrees to radians similarly as before.
Use the same tangent formula: distance = tan((1/120)° × (π/180)) × 234,000 miles.
Calculate the tangent of (1/120)° in radians (approximately 0.000145444) and multiply by 234,000 miles.
This results in approximately 34 miles from the assigned target.

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?
A system of equations to represent the situation with Sparkles the Clown is: 2p + 2g = 12 for Jenny's party and 4p + 5g = 27 for Roger's party. We can use substitution or elimination methods to solve for 'p' and 'g' to determine the number of balloons needed for each animal.
Explanation:To write a system of equations based on the given situation with Sparkles the Clown, we will let 'p' represent the number of balloons needed for a poodle and 'g' represent the number of balloons needed for a giraffe. From Jenny's party, we know that 2 poodles plus 2 giraffes used a total of 12 balloons. From Roger’s party, we learn that 4 poodles plus 5 giraffes used a total of 27 balloons. Therefore, our system of equations to represent this situation is:
2p + 2g = 12 (Jenny's party)4p + 5g = 27 (Roger's party)To solve this system of equations, we could use methods such as substitution or elimination to find the values of 'p' and 'g' which would tell us how many balloons are required for each balloon animal.
Final answer:
To find out how many balloons are required for each balloon animal, we set up a system of equations with p representing the number of balloons for a poodle, and g for a giraffe. The system is based on the balloon usage at two parties, resulting in the equations 2p + 2g = 12 and 4p + 5g = 27.
Explanation:
To solve the problem of how many balloons Sparkles the Clown needs for each type of balloon animal, we need to set up a system of linear equations based on the given information. We will let p represent the number of balloons needed for a poodle, and g represent the number for a giraffe.
From Jenny's party, we have the first equation:
2p + 2g = 12
From Roger's party, we have the second equation:
4p + 5g = 27
Now, we have established our system of equations:
1) 2p + 2g = 12
2) 4p + 5g = 27
Solving this system will give us the number of balloons needed to make each type of balloon animal.

A plane is racing a helicopter to a runway traveling 31 mph and it tends to burn 5 gallons of gas ever 3 minutes. Whilst the helicopter is traveling at a speed of 45 mph burning 7 gallons of gas every 5 minutes. They both started with the same amount of fuel (80 gallons) and both have the same amount to travel ( 640 miles) Who will make it first using the less amount of fuel?
Does this problem work?
If so what is the answer?
Show your work please
Answer:
The problem does not work.
Step-by-step explanation:
The plane with speed of 31 mph will cover 640 miles in [tex]\frac{640}{31} = 20.64[/tex] hours.
Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.
So, it will burn in 20.64 hours [tex]\frac{5 \times 20.64}{0.05} = 2064[/tex] gallons.
Now, the helicopter with speed of 45 mph will cover 640 miles in [tex]\frac{640}{45} = 14.22[/tex] hours.
Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.
So, it will burn in 14.22 hours [tex]\frac{7 \times 14.22}{0.083} = 1194.48[/tex] gallons.
But both of them starts with only 80 gallons of fuel.

Two cars at the same point on I-75. One heads north going 75mph and one heads south going 60mph. How long will it take for the cars to be at 420 miles apart?
It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.
Step-by-step explanation:
Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.
Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.
x = distance to be covered / distance being traveled every hour
= 420 / 135 = 3.11 hours
We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.

Answer:
It is proved that AB = 2 × DE.
Step-by-step explanation:
The three vertices of triangle ABC are A(-2,6), B(8,-2) and C(-8,-4).
So, the mid point of AC (say D) has coordinates [tex](\frac{- 2 - 8}{2},\frac{6 - 4}{2}) = (-5,1)[/tex].
And the mid point of BC (say E) has coordinates [tex](\frac{8 - 8}{2}, \frac{- 2 - 4}{2}) = (0, - 3)[/tex].
Now, the length of DE will be [tex]\sqrt{(- 5 - 0)^{2} + (1 + 3)^{2}} = \sqrt{41}[/tex] units.
Again, the length of AB will be [tex]\sqrt{(- 2 - 8)^{2} + (6 + 2)^{2}} = 2\sqrt{41}[/tex] units.
