Answer:

$N=50t$

Step-by-step explanation:

Let N represent number of miles traveled after traveling t hours.

We have been given that you are traveling on a bus at camp at a speed of 50 mph. We are supposed to write an equation for the given scenario.

We know that distance equals speed times time.

$\text{Distance}=\text{Speed}\times \text{Time}$

Substitute given values:

$N=50t$

Therefore, our required equation would be $N=50t$ .

AleksandrR [38]

Answer:

The total change in his account is of -$85, that is, a loss of $85

Step-by-step explanation:

We combine these changes. So

On Tuesday, he withdrew $90 from his account, which means that, the total change, initially of $0, is now of -$90.

On Thusday, he deposited $20, which means that the total change of -$90 is now of -$90 + $20 = -$70

On Friday, he wrote a check of $15, removing 15 from his account, which means the total change will be of -$70 -$15 = -$85

Before a renovation a movie theater had 117 seats after the renovation theater had 173 what is the approximate percentage increa

aev [14]

Answer:

47.86%

Step-by-step explanation:

Total number of seats in a movie theater Before a renovation = 117

Total number of seats in a movie theater after a renovation = 173

We need to find the percentage increase of the number of seats. It can be calcualted as :

$\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%$

So, the increase in percentage is 47.86%.

Tell whether the data in the table can be modeled by a linear equation. Explain.

anastassius [24]

Answer:

y = -3x + 7

Step-by-step explanation:

Choosing two points from the given table:

Let (x1, y1) = (-3, 16)

(x2, y2) = (-1, 10)

Plug these given values into the slope formula:

m = (y2 - y1)/(x2 - x1)

= (10 - 16) / (-1 - (-3))

= -6 / (-1 + 3)

= -6/2

= -3

Therefore, the slope is -3.

Next, choose one of the points and plug into the <u>point-slope form</u>:

Let's use (-1, 10) as (x1, y1):

y - y1 = m(x - x1)

y - 10 = -3(x - (-1))

y - 10 = -3(x + 1)

y - 10 = -3x - 3

Add 10 on both sides to isolate y:

y - 10 + 10 = -3x - 3 + 10

y = -3x + 7

Tom had a total of $220 and he spent $35 on a basketball ticket . What percent of his money did he have left?

RoseWind [281]

Answer: 84.09%

Step-by-step explanation:

1. 220-30=? ?=185

2. Divide 185 by 220 (as a fraction, 185 out of 220 is 185/220 which also means divide) 185 divided by 220 is about 0.8409

3. Multiply 0.8409 by 100 (since there is two zeros in 100 we can move the decimal to the right twice which gets you 84.09
