the ski team has a race in 3 hours and it is 120 miles away. the team drives 50 miles each hour. will they arrive at the same time?

Answers

They won't arrive exactly when the race starts, but they will arrive before the race starts because, assuming they leave exactly three hours before the race, they can drive a total of 150 miles in three hours (3h*50mi/h). Because they only need to drive 120 miles, they will make it to the race before it starts.

Enter an equation and an answer to the following question:What is the original list price if the discount is $35 and the discount rate is 10%

Answers

Answer:

The original listed price is $ 350.

Step-by-step explanation:

Since,

$\text{Discount percentage}}=\frac{\text{Discount}}{\text{Marked price}}* 100$

$\implies \text{Marked price}=\frac{\text{Discount}}{\text{Discount percentage}}* 100$

Here, Discount = $ 35 and discount percentage = 10 %,

Let x be the marked price or original listed price,

$\implies x = (35)/(10)* 100=350$

Hence, the original listed price is $ 350.

35=x*10/100
x=10*35=350$

the original list price is $350

Brenda’s scores on the first three of four 100-point science tests were 95, 92, and 89. What score does she need on her fourth science test to ensure an average score of at least 93?. . A) X ≥ 96. B) X ≤ 90. C) X ≥ 88. D) X ≤ 92

Answers

The average is equal to the mean of the data set. It is the total of the data or numbers given divided by the ordinal unit of the data set. In this case, we are given with scores of 95, 92, and 89. To have an average of at least 93, the fourth score should be :
95 + 92 + 89 + x ≥ 93 * 4 where 4 is the number of data points.
x ≥ 96. Test score should be equal or greater than 96.

average of 93

4 scores
(95+92+89+x)/4>93
times 4 both sides
276+x>372
minus 276 both sides
x>96
