10.23 centimeters
surface area is length x width x height
multiply 7 and 5
divide 358 by 35

10.22857 round how u would like, 5 times 7 gets u the area so 358 divided by 35 would get u the remaining side length of 10.22….

Answer:

∠JKH and ∠GHF

Step-by-step explanation:

hey there,

< Corresponding means "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." The lines here are parallel so they are equal.

If you don't understand the meaning of the angles also, feel free to ask me about that too.

The two angles I listed are equal to equal to each other. When you look at the other options, they aren't equal, they might look less or more degrees.

If this won't be a multiple choice but short answer, try looking at angles that look similar and see if they would be able to match with the angle given. >

Hope this helps! Feel free to ask anything else.

Solve the system of equations. −9y+4x−20=0−7y+16x−80=0\begin{aligned} &-9y+4x - 20=0 \\\\ &-7y+16x-80=0 \end{aligned}

gulaghasi [49]

Answer:

(x, y) = (5, 0)

Step-by-step explanation:

$\begin{aligned} &-9y+4x - 20=0 \\ &-7y+16x-80=0 \end{aligned}$

Subtract 4 times the first equation from the second:

(-7y +16x -80) -4(-9y +4x -20) = (0) -4(0)

29y = 0 . . . . . simplify

y = 0 . . . . . . . .divide by 29

4x -20 = 0 . . . . substitute 0 for y in the first equation

x -5 = 0 . . . . . .divide by 4

x = 5 . . . . . . . . add 5

The solution to this system is (x, y) = (5, 0).

The Chandlers are moving across the country. Mr. Chandler leaves 4 hours before Mrs. Chandler. If he averages 70mph and she aver

IRINA_888 [86]

Answer:

It will take 28 hours for Mrs. Chandler to catch up with Mr. Chandler.

Step-by-step explanation:

Given that:

Speed of Mr. Chandler = 70 mph

Distance covered in 4 hours = 70 * 4 = 280 miles

Let,

h be the number of hours.

y be the total distance covered.

y = 70h + 280

Speed of Mrs. Chandler = 80 mph

y = 80h

For catching up, the distance would be same.

80h = 70h + 280

80h - 70h = 280

10h = 280

Dividing both sides by 10

$\frac{10h}{10}=\frac{280}{10}\\h=28$

Hence,

It will take 28 hours for Mrs. Chandler to catch up with Mr. Chandler.
