Pls help I am stuck on this question

Answer:

I think the answer is 3 for 1 length side. And in you need 12 for both length sides. So the total is 36 and one side is 12. Since it's a rectangle,you now know two side lengths since they are the same,just opposite from each other. So 12 + 12 = 24. You do 36 – 24 because you need to get the total number for length which is 12. 12 divided by 2 is 6 which is one length side. You can check by doing 6 + 6 + 12 + 12 and you get 36.

Hope this helped!

Answer:

The width of the patio is 11.29 feet while the length of the patio is 13.29 feet

Step-by-step explanation:

Mathematically, the area of the patio can be calculated by multiplying the length by the breadth of the patio

Thus we have ;

(x + 7)(x + 9) = 150

x^2 + 7x + 9x + 63 = 150

x^2 + 16x + 63 = 150

x^2 + 16x + 63 -150 = 0

x^2 + 16x -87 = 0

we can use the quadratic formula to solve this completely

x = {-b ± √(b^2 - 4ac)}/2a

where a = 1, b = 16 and c = -87

Plugging the values we have

x = {-16 ± √(16^2 - 4(1)(-87)}/2

x = {-16 ± √(256+ 348)}/2

x = {-16 ± √(604}/2

x = (-16 + 24.58)/2 or (-16-24.58)/2

x = 4.29 or -20.29

Choosing x = -20.29 will make our dimensions negative, so we ignore it and make do with the positive value only

Thus our dimensions are 4.29 + 7 and 4.29 + 9

This is equal to 11.29 feet and 13.29 feet respectively

Answer:

The range is 12

Step-by-step explanation:

the range is the biggest number minus the smallest

the biggest number is 33

the smallest number is 21

so 33-21=12 so

The range is 12

Answer: 12

Step-by-step explanation: The range is the difference between the greatest number in the data set and the least number in the data set which in this case is 33 - 21 or 12.

So the range of this data set is 12.

center = [tex](-4,8)[/tex]

Radius = 7 units

Step-by-step explanation:

Given: Equation of circle is [tex]x^2+y^2+8x-16y+31=0[/tex]

To find: Radius and center of the circle

Solution:

Equation of circle is [tex](x-a)^2+(y-b)^2=r^2[/tex]

Here, [tex](a,b)[/tex] is the center and r is the radius.

[tex]x^2+y^2+8x-16y+31=0\\\left [ x^2+2(4)x+4^2 \right ]+\left [ y^2-2(8)y+8^2 \right ]+31=4^2+8^2[/tex]

Use formula [tex](u+v)^2=u^2+v^2+2uv[/tex]

[tex](x+4)^2+(y-8)^2=16+64-31\\(x+4)^2+(y-8)^2=49=7^2[/tex]

On comparing this equation with equation of circle,

center = [tex](-4,8)[/tex]

Radius = 7 units

Complete question:

Noah drew a triangle so that all the sides are 5 inches long. He wants to draw a new triangle, but increase the length of each side by x inches. The perimeter of the new triangle is 24 inches. Find the value of x and length of the new side.

Answer:

x = 3 inches

The length of the new sides of the triangle is 8 inches

Step-by-step explanation:

If each of the sides of the original triangle is 5 inches, then it is an equilateral triangle.

Let the length of each of the side of the new triangle be, A, B and C.

A = 5 + x

B = 5 + x

C = 5 + x

A + B + C = 24

(5 + x) + (5 + x)  + (5 + x) = 24

15 + 3x = 24

3x = 24 -15

3x = 9

x = 9/3

x = 3

A = B = C = 5 + x = 5 + 3 = 8 inches

The length of the new sides of the triangle is 8 inches

Answer:

Step-by-step explanation:

Experimental means what actually happened

P(odd) = (number of 1 + number of 3 + number of 5) / total

           = (10+8+8) / 50

           = 26/50

           = 13/25 = 52%

Theoretical means  what we expect to happen

P (odd) = (number of 1 + number of 3 + number of 5) / total

             =(1+1+1)/6

             =1/2 = 50%

We rolled an odd just a little more than the expected amount of times

Answer:

y=x-4

Step-by-step explanation:

The general scaffold for the slope intercept form is y=mx+b, where m is the slope and b is the y intercept. You can rearrange the equation that you are given like this:

2x-2y=8

-2y=-2x+8

y=x-4

Hope this helps!

Answer:

Rearrange the equation so that it is written in slope intercept form:

y=mx+b.

2x+2y=8.

2y=−2x+8.

y=−x+4.

Answer:

[tex]-\frac{15}{4}[/tex]

Step-by-step explanation:

To find the slope or the gradient of a line you have to utilise the formula

[tex]\frac{y2-y1}{x2-x1}[/tex]

Y₂ = -7

Y₁ = 8

X₂ = 7

X₁ = 3

So,

[tex]\frac{-7-8}{7-3}[/tex]

→ Simplify

[tex]-\frac{15}{4}[/tex]

By using the given points, we will see that the slope is -15/4.

If we know that a given line passes through two known points (x₁, y₁) and (x₂, y₂), then the slope can be written as:

[tex]s = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Here the line passes through the points (3, 8) and (7, -7).

Using the above formula, we can see that the slope is:

[tex]s = \frac{-7 - 8}{7 - 3} = \frac{-15}{4}[/tex]

Answer:

f(x) = x² + 7x + 12

Step-by-step explanation:

Given that the zeros are x = - 3 and x = - 4, then the factors are

(x - (- 3)) and (x - (- 4)), that is (x + 3) and (x + 4)

f(x) is the product of the factors, that is

f(x) = (x + 3)(x + 4) ← expand using FOIL

f(x) = x² + 7x + 12

There are 118 adult tickets sold

This is because 354/3 =118

and 118+118=236

236 are the child tickets

therefore 118 are the adult tickets.

Hope this helped!

The total number of adult ticket sold is 118 tickets.

Let's write "x" to represent how many adult tickets were sold.

The information provided indicates that there were twice as many student tickets sold as adult tickets. The quantity of student tickets sold can therefore be stated as 2x.

There were 354 total tickets sold, which includes both student and adult tickets.

We may construct an equation based on the total number of tickets to resolve this issue:

x + 2x = 354

Combining comparable variables

3x = 354

x = 354 / 3

x = 118

118 adult tickets were consequently sold.

[tex] x^2 + \frac{1}{49} =1 [/tex]

And solving for x we got:

[tex] x^2 = 1- \frac{1}{49}[/tex]

[tex] x^2 = \frac{48}{49}[/tex]

And taking square root we got:

[tex] x = \sqrt{\frac{48}{49}}= \frac{\sqrt{48}}{7} = \frac{4\sqrt{3}}{7}[/tex]

Step-by-step explanation:

For this case we have the following point given [tex] P(x , -1/7)[/tex]

And we want to find the value of x, since P lies on the unitray circle if we find the distance from P to the center of the unitary circle (0,0) we need to get 1. Using the definition of Euclidean distance that means:

[tex] d = \sqrt{(x -0)^2 +(-1/7 -0)^2}=1[/tex]

And if we square both sides of the last equation we got:

[tex] x^2 + \frac{1}{49} =1 [/tex]

And solving for x we got:

[tex] x^2 = 1- \frac{1}{49}[/tex]

[tex] x^2 = \frac{48}{49}[/tex]

And taking square root we got:

[tex] x = \sqrt{\frac{48}{49}}= \frac{\sqrt{48}}{7} = \frac{4\sqrt{3}}{7}[/tex]

Answer:

71.57% of student heights are lower than Darnell's height

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

[tex]\mu = 150, \sigma = 20[/tex]

Darnell has a height of 161.4 centimeters. What proportion of student heights are lower than Darnell's height?

This is the pvalue of Z when X = 161.4.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{161.4 - 150}{20}[/tex]

[tex]Z = 0.57[/tex]

[tex]Z = 0.57[/tex] has a pvalue of 0.7157

71.57% of student heights are lower than Darnell's height

Answer:

0.7157

Step-by-step explanation:

Darnell's height is 161.4 - 150 = \goldD{11.4}161.4−150=11.4161, point, 4, minus, 150, equals, start color #e07d10, 11, point, 4, end color #e07d10 relative to the mean.
