Aleks04 [339]

Answer:

Pi/3 radians also measures 60 degrees not 30

Step-by-step explanation:

Pi/3 x 180/pi=180pi/3pi

Since both have pi they cancel out leaving 180/3, which equals 60.

A taxi cab charges $1.50 for the flat fee and $0.50 for each mile. Write an inequality to determine how many miles Sharon can tr

Korvikt [17]

Answer:

C. $0.50x+1.50\leq 25$

Step-by-step explanation:

Let x represent number of miles.

We have been given that a taxi cab charges $1.50 for the flat fee and $0.50 for each mile.

The cost of riding x miles would be $0.50x$ and the total cost of riding x miles would be $0.50x+1.50$ .

Since Sharon has only $25 to spend on the taxi ride, so the cost of riding x miles on taxi must be less than or equal to 25.

We can represent this information in an inequality as:

$0.50x+1.50\leq 25$

Therefore, option C is the correct choice.

6) Kate wants to buy some daisies for $6.99, some potting soil for $3.98, and a ceramic pot for $7.95. She has $20.00. Which num

Mama L [17]

By taking a subtraction, we will see that the change that Kate receives is $1.08

<h3></h3><h3>How to get the change?</h3>

The change will be given by the difference between what Kate has, and the cost of all the items she buys.

She has $20.00, and the costs are: $6.99, $3.98, and $7.95.

Then the change will be:

C = $20.00 - $6.99 - $3.98 - $7.95 = $1.08

We conclude that the change is $1.08

What is the solution of 3 sqrt x+8=-4?

ryzh [129]

Answer:

$x=-72$

Step-by-step explanation:

The given equation is $\sqrt[3]{x+8}=-4$ .

We cube both sides of this equation to obtain;

$(\sqrt[3]{x+8})^3=(-4)^3$ .

This implies that;

$(x+8)=-64$

We group similar terms to obtain;

$x=-64-8$

We simplify the right hand side of the equation to obtain;

$x=-72$

Therefore x=-72 is the solution of the given equation.
