Answer:

It will take 17.5 minutes to reach 50 degrees F.

Step-by-step explanation:

Current temperature = -13 degrees F

With the engine on, the temperature goes up by 3.6°F per minute.

Let us assume that it takes x minutes to reach 50 degrees F.

So, the time taken will be =

$-13+3.6(x)=50$

=> $3.6x=50+13$

=> $3.6x=63$

x = 17.5 minutes

The expression that tells how much the temperature needs to change from -13°F to 50°F is : $-13+3.6(x)=50$

It will take 17.5 minutes to reach 50 degrees F.

Answer:

Please see the answers below:

Step-by-step explanation:

The wrong answers are deleted only the correct answers are listed below:

Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.

Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.

Claire saves $320 in 16 weeks. The unit rate is $20 per week.

% increase in price of gas = [(New Price - Original Price) / Original Price] x 100

% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100

% increase in price of gas = [$0.3 / $2.18] x 100

% increase in price of gas = 13.76%

Please please please answer this I have the answer I just need the work for it!!!!!

MrRa [10]

Answer:

x=80

Step-by-step explanation:

First of all, you must find the length of the side to add with 36 to equal 100. This would give you 64. So once you do that, you can do pythagorean theorem to find the length of x. This would give you 64^2 + 48^2 = x^2. Once you have this equation, you square your terms to get; 4,096 + 2,304 = x^2. After you add them you will now have 6,400 = x^2. Once you have this, you will need to do the square root of both sides of the equation; sqrt(6400) = x. This gives you x = 80.

Hope this helps!

Find the midpoint of the segment with the given endpoints. (9.-9) and (2.-10)

kondor19780726 [428]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{(5.5 \: , \: - 9.5)}}}}}$

Step-by-step explanation:

Let the points be A and B

Let A ( 9 , -9 ) be ( x₁ , y₁ ) and B ( 2 , - 10 ) be ( x₂ , y₂ )

<u>Finding</u><u> </u><u>the</u><u> </u><u>midpoi</u><u>nt</u>

$\boxed{ \sf{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} }}$

$\longrightarrow{ \sf{midpoint = ( \frac{9 + 2}{2} , \: \frac{ - 9 + ( - 10)}{2}}} )$

$\longrightarrow{ \sf {midpoint = ( \frac{11}{2} \: , \: \frac{ - 9 - 10}{2}})}$

$\longrightarrow{ \sf{midpoint = (5.5 \: , \: \frac{ - 19}{2}}} )$

$\longrightarrow{ \sf{midpoint = (5.5 \: , - 9.5}})$

Hope I helped!

Best regards! :D

Agata [3.3K]

Answer:

32 Roller Coasters

Step-by-step explanation:

There are a total of 112 rides in Cedar Point.

$\frac{2}{7}$ of these rides are roller coasters.

In Algebraic Word Problems, the term "OF" means Multiplication.

Number of Roller Coasters = $\frac{2}{7}$ of 112

= $\frac{2}{7}$ X 112

=2 x 16

=32

There are 32 Roller Coasters in Cedar's point's collection of rides.
