Answer:
y
Step-by-step explanation:
because every time 7 will multiplied by x it will equals to y. so y will be the constant
Answer:
y
Step-by-step explanation:
y=kx y = k x , y varies directly with x and k . The constant of variation, k , is 7
Your mom is repainting your younger brother’s room. She is going to project the image shown below onto his wall so that she can paint an enlarged version as a mural. The length of the image of the train measures 2 inches.
Determine how long the mural will be if the projector uses a scale where 1 inch of the image represents 2 1 half feet on the wall.
Answer:
5 feet
Step-by-step explanation:
The graph will show the height of the red car as the time increases. Predict what this graph will look like before pressing start to run the ferris wheel.
How long does it take for the person riding the ferris wheel to make a complete revolution?
One revolution is ____
0 seconds
30 seconds
60 seconds
or
80 seconds
As per the graph, the time it takes for the person riding the ferris wheel to make a complete revolution is typically 60 seconds.
When the ferris wheel starts, the height of the red car will initially increase as it ascends from the ground level. As the ferris wheel continues to turn, the red car will reach its maximum height, usually at the topmost position of the ferris wheel, and then descend back to the ground level. This motion will repeat as the ferris wheel continues to rotate.
Now, let's determine how long it takes for the person riding the ferris wheel to make a complete revolution. One revolution corresponds to the time it takes for the ferris wheel to complete one full cycle of motion, going from its initial position, through its highest point, and back to its initial position. This time can be calculated by finding the time period of the sinusoidal function representing the height of the red car.
To find the time period, we need to know the duration for one complete cycle of the sine wave, which is the time it takes for the ferris wheel to complete one revolution. The time period can be derived from the angular speed of the ferris wheel. If we know the angular speed (usually given in rotations per minute or radians per second), we can calculate the time it takes for one revolution.

16/61
Step-by-step explanation:
(a + b)^5 / a - 2b^2
= (6 + -8)^5 / 6 - 2(-8)^2
= (6 - 8)^5 / 6 - 2(-8)^2
= -32 / -122

What is 2(n−3)=4n+1?
n=??
Answer:
n = -7/2
Step-by-step explanation:
2(n - 3) = 4n + 1
=> 2n - 6 = 4n + 1
=> -6 - 1 = 4n - 2n
=> -7 = 2n
=> n = -7/2
-4(-2x + 5) + 2x + 3 =-11
Answer:
x = 3/5
Step-by-step explanation:
-4(-2x + 5) + 2x + 3 =-11
Distribute
8x-20 +2x+3 = -11
Combine like terms
10x-17 = -11
Add 17 to each side
10x-17+17 = -11+17
10x =6
Divide by 10
10x/10 = 6/10
x = 3/5
Does the following table show a proportional relationship between the variables x and y?
PLEASE HELP!!!
Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.
pages---> 4/3=32/3
hours---> 1/4 = x
Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2
Answer:
First, we know that:
1 1/3 = 4/3
10 2/3 = 32/3
15 minutes = 0.25 hours
Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.
From the information, we can tell that:
Lee can type:
4/3 pages in 0.25 hours
32/4 pages in x hours
So x should be:
x = (32/4 . 0.25)/4/3 = 2 (hours)
So it takes Lee 2 hours ro type 10 2/3 pages
Step-by-step explanation:
Determine if the lines are parallel, perpendicular, neither or the same line: y = -2x + 1 and -2x + 4y = 5.
Answer: These lines are perpendicular
Step-by-step explanation:
Let's use slope intercept form, y=mx+b (m=slope, b=y intercept)
Parallel lines have the same slope, or m
y=3x+7 and y=3x+32 are parallel because they have the same mPerpendicular lines have an opposite reciprocal slope
y=2x+13 and y= -1/2+2 are perpendicular because they are reciprocalsy=-2x+1 is already in slope intercept form. Let's change the other problem
-2x+4y=5isolate the y, 4y=2x+5make y by itself, y=2/4x+5/4 or y=1/2x+5/4Here are the two problems: y=-2x+1 and y=1/2x+5/4
Look closer. These lines are actually perpendicular.
Take the second problem's slope, 1/2. Make it a negative reciprocal, which means -2/1 or -2. These lines are perpendicular.

The choose C. 9/8
I hope I helped you^_^
Answer:
A. 49/81
B. -66/5
C. 9/8
Step-by-step explanation:
Slide 1:
Dividing fractions is exactly the same as multiplying fractions, you just flip the second fraction so the expression becomes -7/9*7/-9 which is 49/81.
[tex]\frac{-7}{9}*\frac{7}{-9} =\frac{-49}{-81} =\frac{49}{81}[/tex]
Slide 2:
To make 22 a fraction you just put it over 1 to make 22/1 and you just multiply across. -66/5
Slide 3:
To transform a mixed number into an improper fraction, you multiply the denominator by the whole number and then add the numerator. You take that number and put it over the denominator. You should now have -9/2. Multiply across. Cancel out the negatives. 9/8

can you help me its the one where it says to find the value of a and b
Answer:
2b + 42 = 134 —> Opposite angles
2b= 134 – 42
2b= 92
b= 92/2
b= 46(2b+42) = 2(46)+42 = 92 +42= 134°
134 + (3a+4) =180
134+3a+4=180
3a+138=180
3a= 180 – 138
3a = 42
a=42/3
a=13I hope I helped you^_^

Answer: 3.2
Step-by-step explanation: Exponentiation: 2 ^ 2 = 4
Multiple: the result of step No. 1 * 1 = 4 * 1 = 4
Multiple: 2 * 5 = 10
Divide: the result of step No. 2 : the result of step No. 3 = 4 : 10 = 0.4 = 2/
5
Exponentiation: 2 ^ 5 = 32
Multiple: the result of step No. 4 * the result of step No. 5 = 2/5* 32 = 2 · 32/5·1 = 64/5
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(64, 5) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - two fifths multiplied by thirty-two = sixty-four fifths.
Multiple: the result of step No. 6 * 1 = 64/
5 * 1 = 64 · 1/5 · 1
= 64/5
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD (64, 5) = 1. In the next intermediate step, the fraction result cannot be further simplified by canceling.
In words - sixty-four fifths multiplied by one = sixty-four fifths.
Exponentiation: 2 ^ 2 = 4
Divide: the result of step No. 7 : the result of step No. 8 = 64/5
: 4 = 64/5
· 1/4
= 64 · 1/5 · 4
= 64/20
= 4 · 16/4 · 5
= 16/5
Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 4/1 is 1/4) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step, , cancel by a common factor of 4 gives 16/5
In words - sixty-four fifths divided by four = sixteen fifths.

what is the area of a semi circle when the diameter is 6
Answer: 14.13
Step-by-step explanation:
Your answer is 14.13
First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.
To find the radius, we need to divide the diameter by two, which is 3.
So like
3.14 x 3^2/2
3.14 x 9/2
28.26/2
A=14.13
Answer:
14.13
Step-by-step explanation:
normal circle area equation = r^2*3.14
6/2=3
3*3*3.14
= 28.26
it's a semicircle so /2
=14.13
