Given that triangle ABC is a right triangle, select a set of possible side length measures.

ad-work [718]

You didn't supply any rules or constraints so.... 1 in., 1 in., and 1 in.

You can use the Pythagorean Theorem to check if the side lengths are appropriate.

$a^2 + b^2 = c^2$

$1^2 + 1^2 = 1^2$ –this is true.

Ray has found that his new car gets 31 miles per gallon on the highwayand 26 miles per gallon in the city. He recently drove 285

Mkey [24]

Answer:

$Highway = 155\ miles$

$City = 130\ miles$

Step-by-step explanation:

Given

$Highway = 31mi/gallon$

$City = 26mi/gallon$

$Total\ Miles = 285$

$Total\ Gallons = 10$

Required

Determine the number of miles driven on the highway and on the city

Represent the gallons used on highway with h and on city with c.

So, we have:

$c + h = 10$ ---- gallons used

and

$31h + 26c = 285$ --- distance travelled

In the first equation, make c the subject

$c = 10 - h$

Substitute 10 - h for c in the second equation

$31h + 26c = 285$

$31h + 26(10 - h) = 285$

Open bracket

$31h + 260 - 26h = 285$

Collect like terms

$31h - 26h = 285 - 260$

$5h = 25$

Make h the subject

$h = \frac{25}{5}$

$h = 5$

Substitute 5 for h in $c = 10 - h$

$c = 10 - 5$

$c = 5$

If on the highway, he travels 31 miles per gallon, then his distance on the highway is:

$Highway = 31 * 5$

$Highway = 155\ miles$

If in the highway, he travels 26 miles per gallon, then his distance on the highway is:

$City = 26 * 5$

$City = 130\ miles$

Wendy opens a bank account with money she has saved. After this initial deposit, Wendy then deposits the same amount of money ea

Bess [88]

If the table is:

x | y

------

1 | 76

------

2 | 92

---------

3 | 108

-----------

4 | 124

-------------------------------------------------------------------------------------------------------------------

Find the change inbetween each amount per week

92 - 76 = 16

108 - 92 = 16

etc.

This means that her initial deposit should be subtracting 16 from her first deposit.

76 is the amount first deposited

76 - 16 = 60

A) $60 should be your answer

hope this helps
