Answer:

1)Distance covered by cyclist=3.75 miles.

Time =0.3 hours.

Speed= Distance ÷Time

Speed =3.75÷0.3=12.5 miles per hour.

2) Speed = 12.5 miles per hour, Distance = 4.5 miles .

Time = Distance ÷Speed.

Time = 4.5÷12.5=0.36 hours.

Time taken to cover 4.5 miles is 0.36 hours.

Emmy throws a doggy toy up in the air. The path of the toy is modeled by the function f(x)=−x^2+4x+5, where x is the number of f

Molodets [167]

Answer:

9feet

Step-by-step explanation:

Given the path of the toy modeled by the function f(x)=−x^2+4x+5, where x is the number of feet the toy is from Emmy and f(x) is the height of the toy.

AT maximum height, the velocity of the toy will be zero. Hence;

df(x)/dx = 0

-2x + 4 = 0

-2x = -4

x = -4/-2

x = 2

Get the maximum height;

Substitute x = 2 into the given function;

f(x)=−x^2+4x+5

f(2)=−2^2+4(2)+5

f(2) = -4+8+5

f(2) = 9feet

Hence the maximum height of the toy is 9feet

Christian reads 14 book every 23 week.

mihalych1998 [28]

Picture 1: The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads $\frac{3}{8}$ books per week.

Picture 3: 80% is equal to $\frac{4}{5}$ .

Step-by-step explanation:

Picture 1: Veena ate lunch at a deli. She ordered turkey sandwich for $9.25 and a salad for $4.35. The tax was 7.5%. What is the amount of tax for Veena's meal.

Given,

Price of turkey sandwich = $9.25

Price of salad = $4.35

Total amount = 9.25+4.35 = $13.60

Tax = 7.5%

Amount of tax = 7.5% of total cost

Amount of tax = $\frac{7.5}{100}*13.60$

Amount of tax = $\frac{102}{100} = \$1.02$

The amount of tax for Veena's meal is $1.02

Picture 2: Christian reads 1/4 book every 2/3 week. How many books does Christian read per week?

Given,

Books read every 2/3 weeks = 1/4 books

$\frac{2}{3}\ weeks=\frac{1}{4}\ books\\$

For determining the number of books read per week, we will multiply both sides by $\frac{3}{2}$

$\frac{3}{2}*\frac{2}{3}\ week=\frac{1}{4}*\frac{3}{2}\ books\\\\1\ week = \frac{3}{8}\ books\\\\$

Christian reads $\frac{3}{8}$ books per week.

Picture 3: What percent is equivalent to $\frac{4}{5}$ ?

We will multiply the given fraction with hundred for calculating the percentage.

$\frac{4}{5}*100\\\\\frac{400}{5}\\\\80\%$

Therefore,

80% is equal to $\frac{4}{5}$ .

At Silver Gym, membership is $35 per month, and personal training sessions are $30 each. At Fit Factor,

Vanyuwa [196]

Answer:

5 sessions each

Step-by-step explanation:

Let the personal training sessions be x.

Then at Silver Gym Sarah would spend:

35 + 30x

And at Fit Factor she would spend:

85 + 20x

Since total costs are same, the amounts will be equal:

35+30x = 85 + 20x
30x - 20x = 85 - 35
10 x = 50
x= 50/10
x= 5

So Sarah would buy 5 training sessions for each of the gyms.

And she would spend $185 at each.
