Rotate point H 90 degrees counterclockwise about the origin. What is the algebraic expression?

Damien Smart is trying to decide whether to lease or purchase a new car costing $18,000. If he leases, he’ll have to pay a $600

gizmo_the_mogwai [7]

$the\ lease:\\\\ \$450\cdot36(payments)- \$600(security)=\$16,200-\$600=\$15,600 \\\\ the\ purchase:\\\\down\ payments+payments+sales\ tax- residual\ value= \\\\=\$2,400+\$515\cdot36+\$1,080-\$6,500=\$2.400+\$18,540-\$5420=\\\\=\$15,520\\\\\$15,520$

Please help calculate the total surface area. Thanks

Gnoma [55]

Answer: 70cm³

EXPLANATION:

1/2 x base x height x 2 (this is to find the surface area of one of the triangular faces since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 3 x 3 x 2 ← (to get the height of the triangle substract 7 from 10)

1/2 x 18 ← (multiply 3x3x2=18)

9cm³ ←(since 18 is 2x9 your answer is 9cm³)

1/2 x base x height x 2 (this is to find the surface area of the other triangular face with different measurements and since the other side of the triangular shape has the same measurements you should multiply it by 2 straight away since it makes it easier for you)

1/2 x base x height x 2

1/2 x 4 x 3 x 2 ← (to get the height of the triangle substract 7 from 10)

1/2 x 24 ← (multiply 4x3x2=24)

12cm³ ←(since 24 is 2x12 so your answer is 12cm³)

Then next you have to find the surface area of one face of the rectangle and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 3x7= 21cm³

then find the area of the other rectangular face with different measurements and multiply it by 2 since the back side of the rectangle has the exact same measurements. The formula to find the area of a rectangle is area= length x breath

A= 4x7= 28cm³

FINALLY

add all the areas of the faces you have found and you'll get the total surface area!

9+12+21+28=70cm³

Thank you! I hope you understood something and I hope you have a great day! good luck!

-)) t multiplied by 52 is the same as 349

yawa3891 [41]

Hey there,

The word problem is as follows:

t multiplied by 52 is the same as 349

In numbers this would mean t x 52 = 349. Now to solve for t we would do the opposite of multiplication which is is division.

So...

349 ÷ 52 = t and t = 6 $\frac{37}{349}$

The answer would be t is equal to 6 and $\frac{37}{349}$ or 6.712

Hope I helped,

If Amanda walks at an average speed of 2.72 miles per hour how long will it take her to walk 6.8 miles

Kipish [7]

It would take her about 2.5 hours
