I think the question 26 on the first page is C sorry if I'm wrong

Step-by-step explanation:

Answer:

26 is c, 20 is b, 30 is c

Step-by-step explanation:

26:

The relationship between 2,560 and 256 is that 2,560 is 10 times 256, and the only options that include "10 x" is b and c and b has (2+5+6) which doesn't equal 256, whereas c does.

20:

The bottom layer is 15 blocks, so then add the two more on top of the bottom layer and it's 17, so b.

30:

The width of the prism is 2, the length is 8, and the height is 4, so 2x8x4 is 64. They want a prism that's 1/4 the volume, so 64/4 is 16. (You could also just take 4 out of the 2x9x4 equation and get 2x8 which is 16).

x=-4/7 and the slope is 7

Answer:

3

Step-by-step explanation:

The slope of a line is the rate of change

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (2, 12 ) and (x₂, y₂ ) = (0, 4) ← 2 ordered pairs from the table

m = [tex]\frac{4-12}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4

y = 7x + 4 ← is in slope- intercept form

with slope m = 7

Difference between rates of change = 7 - 4 = 3

Solve Each equation.

jill has a rectangular table that is 3 1/2 ​ feet long and 1 3/4 ​ feet wide. what is the area of jill’s table?

Answers

Answer:

6 1/8 feet squared

Step-by-step explanation:

The Area of Jill's table is 49/ 8 feet².

What is area?

The total space occupied by a flat (2-D) surface or the shape of an object is defined as its area. The area of a plane figure is the space enclosed by its boundary. The number of unit squares that cover the surface of a closed form is the figure's area.

and, Area of Rectangle = length x width

We have,

Length of rectangular table = 3 1/2 feet = 7/2 feet

Width of rectangular table = 1 3/4 feet = 7/4 feet

So, the Area of rectangular table

= l w

= 7/2 x 7/4

= 49/ 8 feet²

Thus, the Area is 49/ 8 feet².
