i = 3c

i = c + 14

set both equations equal to each-other, we can

solve for c, we must.

3c = c + 14

subtract c from both sides, we must.

2c = 14

divide both sides by 2, we must.

c = 7

7 years old, Christopher is.

Answer: Christopher is 7 years old.

Step-by-step explanation: If I were Ishaan's age and C were Christopher's age, if Ishaan is 3 times the age of Chris we can do

I=3c

We also know that Ishaan is 14 years older than Chris. So we can set the equation as:

I=14+c

If we insert I=3c into I=14+c, it is

3c=14+c

2c=14

c=7

Therefore, chris is 7 years old.

Val measures the diameter of a ball as 6 inches. How many cubic inches of air does this ball hold, to the nearest tenth? Use 3.1

7nadin3 [17]

Answer:

The ball holds 113.0 cubic inches of air

Step-by-step explanation:

Firstly we need to know the shape of the ball

A ball is spherical in shape

So to know the number of cubic inches, we have to find the volume of air in the ball

Mathematically, we can do this by finding the volume of the ball using the formula for the volume of a sphere

The formula for the volume of a sphere is ;

V = 4/3 * pi * r^3

in this case, r = d/2 = 6 /2 = 3 inches

where r is the radius of the ball and d is the diameter of the ball

So, substituting these values , we have

V = 4/3 * 3.14 * 3^3 = 113.0 cubic inches

Dafna1 [17]

Answer:

To spend at most $93, they need to rent the room less than or equal 13 hours.

Step-by-step explanation:

The complete question is

To rent a certain meeting room, a college charges a reservation fee of $15 and an additional fee of $6 per hour. The chemistry club wants to spend at most $93 on renting a room. What are the possible numbers of hours the chemistry club could rent the meeting room? Use t for the number of hours. Write your answer as an inequality solved for t,

Let

t ----> the number of hours

we know that

I this problem the word "at most" means "less than or equal to"

The number of hours rented multiplied by the cost per hour, plus the reservation fee, must be less than or equal to $93

The inequality that represent this situation is

$6t+15\leq 93$

solve for t

subtract 15 both sides

$6t\leq 93-15$

$6t\leq 78$

Divide by 6 both sides

$t\leq 13\ hours$

therefore

To spend at most $93, they need to rent the room less than or equal 13 hours.

Can two vertical angles form a linear pair?

weqwewe [10]

Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) A Linear Pair is two adjacentangles whose non-common sides form opposite rays. ... ∠1 and ∠3 are not vertical angles (they are a linear pair).
