Answer:

298-275 = 23 cm thus D) is the answer

Step-by-step explanation:

First Box:

length l = 9.5 cm

width w = 5 cm

height h = 7 cm

diagonal d = 12.8160056 cm

total surface area S_tot = 298 cm2

lateral surface area S_lat = 203 cm2

top surface area S_top = 47.5 cm²

bottom surface area S_bot = 47.5 cm²

volume V = 332.5 cm³

Second Box:

length l = 7.5 cm

width w = 5 cm

height h = 8 cm

diagonal d = 12.0519708 cm

total surface area S_tot = 275 cm²

lateral surface area S_lat = 200 cm²

top surface area S_top = 37.5 cm²

bottom surface area S_bot = 37.5 cm²

volume V = 300 cm³

For what value of x must ABCD be a parallelogram?
Svetach [21]

Answer:

x  = 3

Step-by-step explanation:

to be a parallelogram opposite sides have to be equal

so we have

DC = AB\\\\20x-7 = 16x+5

now solve for x

20x-7+7 = 16x+5+7\\\\20x = 16x + 12\\\\20-16x = 16x+12-16x\\\\4x = 12\\\\x = \frac{12}{4} = 3

Please help me find the equation it so hard
nataly862011 [7]

Answer:

y = 4/5x + 3/5  

Step-by-step explanation:

In the slope-intercept form, y = mx + b, we need to find the values of the slope (m) and the y-intercept.

Using points (-7, -5) and (3, 3), we can calculate for the slope of the equation given the formula:

m = \frac{y2 - y1}{x2 - x1}

Let (x1, y1) = (-7, -5)

and (x2, y2) = (3, 3).

Plug the given values into the slope formula:

m = \frac{y2 - y1}{x2 - x1} = \frac{3 - (-5)}{3 - (-7)} = \frac{3 + 5}{3 + 7} = \frac{8}{10} = \frac{4}{5}

Therefore, the slope of the line is 4/5.  

Next, we need to find out the value of the y-intercept (b).

We can use one of the given points, (3, 3), along with the slope (4/5) to solve for the y-intercept:

y = mx + b

3 = 4/5(3) + b

3 = 12/5 + b

Subtract 12/5 from both sides:

3 - 12/5 = 12/5 - 12/5 + b

3/5 (or 0.6) = b

Therefore, the y-intercept is 3/5.

We can now establish our linear equation as:

y = 4/5x + 3/5

the area of sea horese is 108 cm every day it grows by 2% what will be the sea hores area after 2 days
Vitek1552 [10]
First find 2 percent of 108cm which is 2/100*108=2.16
So the sea hores grows 2.16cm every day. In 2 days, the hores will be 2*2.16=4.32cm
