Answer:

659.52 cm^2

Step-by-step explanation:

In order to find the surface area of this figure, we need to know the dimensions of the base. If we assume the base is square, then the distance from its center to the center of one edge is half the dimension of one side of the base.

That center-to-edge distance (x) can be found from the given dimensions using the Pythagorean theorem.

x^2 + (15.4 cm)^2 = (17 cm)^2

x^2 = (289 -237.16) cm^2 = 51.84 cm^2

x = √51.84 cm = 7.2 cm

This means the edge length of the prism base is 2×7.2 cm = 14.4 cm.

The total surface area of the square prism is ...

A = b^2 +2bs . . . where b is the edge length of the base, s is the slant height

A = (14.4 cm)^2 + 2(14.4 cm)(17 cm) = 659.52 cm^2

The total surface area of this square pyramid is 659.52 cm^2.

Answer:

Step-by-step explanation:

[tex]\frac{30}{25sec}[/tex] -----> [tex]\frac{78}{65sec}[/tex] (scale by 2.6)

You cant get the answer by following these steps.

1. To find out how much we must increase with our scaling we must divide the denominators.

[tex]\sqrt[25]{65}[/tex]= 2.6

2. Then, we do the scaling. Multiply the numerator and the denominator by 2.6.

num- 30 x 2.6= 78.0 (DONT FORGET UR DECIMALS)

dem- 25 x 2.6 = 65

3. Now you have your answer and all you need to do is show it in fraction form as seen below the words "step by step explanation"

You have collected data on the average weekly amount of studying time (T) and grades (G) from peers at your university. Changing the measurement from minutes into hours has the following effect on the correlation coefficient:

a. cannot be computed since some students study less than an hour per week
b. does not change the rTG
c. decreases the rTG by dividing the original correlation coefficient by 60
d. results in a higher rTG

Answers

Answer:

b. does not change the rTG

Step-by-step explanation:

If the average weekly amount of studying time and Grade are compared such that a certain correlation Coefficient value is obtained, changing the unit of measurement of any of the variables, will not affect the value of the correlation Coefficient most notably because the value of R, correlation Coefficient is a normalized or standardized value that ranges between - 1 and 1 and hence, resistant to unit changes in the compared variables. Hence, Correlation coeffient for the rate of study and grade obtained will not change even if rate of study is measured in hour.

b. does not change the rTG

Answer:

x = 9

Step-by-step explanation:

The line splits the sides of the triangle in proportion (the ratios of the pieces is the same for both sides).

Setup:

[tex]\frac{8}{3x+1}=\frac{2}{x-2}[/tex]

"Cross multiply."

[tex]2(3x+1)=8(x-2)\\6x+2=8x-16\\18=2x\\9=x[/tex]

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
1) 6x+3y=5
2)y=-1/2x-7
3)y=-2

Answers

Answer:

1) 6x+3y=5

Step-by-step explanation:

1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the two points into the formula and solve:

[tex]m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2[/tex]

So, the slope is -2.

2) Now, identify the slopes of the lines in the options. We already know the slope of [tex]y = -\frac{1}{2} x-7[/tex] is [tex]-\frac{1}{2}[/tex] since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.

To find the slope of [tex]6x + 3y = 5[/tex], isolate y to put the equations into slope-intercept form ([tex]y = mx + b[/tex] format), and whatever the coefficient of the x-term is will be the slope.

[tex]6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}[/tex].

So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.
