In a rectangle, opposite sides are congruent.

So this means that
QT = RS
or
30 = 4x + 10
subtract the 10 from both sides

20 = 4x
divide both sides by 4

5 = x

answer is B. 5

The area of a right triangle with one leg measuring 5 ft. and hypotenuse measuring 13 ft. is_______ a0. Type a numerical answer

Snowcat [4.5K]

Area of the triangle = (1/2)*base*height

For right triangle base and height can be legs.

We have one leg = 5 ft. (Lets think it is a base.)

We need to find the other leg.

We are going to use Pythagorean theorem.

5² + b²=13²

b²=144

b=12 (It is going to be our height.)

Area of the triangle = (1/2)*5*12= 30 ft²

Area of the triangle = 30 ft²

to win a basketball game, one team scored 151 points. They made a total of 62 two-pointers and three pointers how many of the ba

wolverine [178]

That's a huge number of points.

First: Calculate the value of 62 two pointers

62 * 2 = 124

Second: find the number of points that were due to 3 pointers.

151 - 124 = 27

Third: Divide by 3 to find the number of 3 pointers.

27÷3 = 9

Answer: There were 9 three pointers.

Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation. Write a mult

Elina [12.6K]

decrease in temperature if you hike up the mountain 3000 meters is $-30$ ° .

<u>Step-by-step explanation:</u>

Here we have , Hiking up a mountain, you notice that the air temperature drops 10 degrees every 1000 meters increase in elevation . We need to find Write a multiplication expression to represent the decrease in temperature if you hike up the mountain 3000 meters. Let's find out:

For every 1000 meters rise in elevation , there is decrease in 10° of temperature . So , For rise in n meters in elevation , there is decrease in n×10° of temperature i.e

Decrease in temperature = (n/1000)×(-10) i.e.

⇒ (n/1000)×(-10)

⇒ $\frac{n}{1000}(-10)$

At n = 3000 meters:

⇒ $\frac{3000}{1000}(-10)$

⇒ $3}(-10)$

⇒ $-30$ °

Therefore , decrease in temperature if you hike up the mountain 3000 meters is $-30$ ° .
