8 0

Answer:

The ball will take 2.6 seconds to hit the ground again.

Step-by-step explanation:

Sam kicks a soccer ball from the ground. The height of  the ball (in feet) can be modeled with the function,  h(t) = −16t(t − 2.6), where t is the time in seconds  after the ball is kicked.

So, the ball will be at ground when h = 0 = - 16t(t - 2.6)

⇒ t = 0 or t = 2.6.

Therefore, the ball will take 2.6 seconds to hit the ground again. (Answer)

Mariana [72]

Answer:

<h2>1,190cm²</h2>

Step-by-step explanation:

The Area of a triangle is expressed  as 1/2 * base * height. If uma is planning to decorate a blanket with a triangular shape that has a base of 5 centimetres and a height of 7 centimetres, area of the blanket will be expressed as shown;

Area of the blanget = 1/2 * 7 * 5

Area of a blanket = 35/2 = 17.5cm²

If she plans to cut out 68 triangles with these dimensions, the total area will be total number of triangles * area of one triangle i.e 68 * 17.5 = 1,190cm²

What is the measure of X?
vlabodo [156]

Answer:

The answer is B.

Step-by-step explanation:

Given that the total angles in a triangle is 180° so in order to find the value of x, you have to substract 60° and 80° from 180° :

60 + 80 + x = 180

140 + x = 180

x = 180 - 140

x = 40

Sally has to pay a deposit to rent a kayak of $50.00, then she is charged $7.00 per hour
solmaris [256]

Answer:

$92

Step-by-step explanation:

Since Sally plans to keep the kayak for 6 hours and it's $7 per hour we can multiply 6*7 to determine how much she will be charged for keeping the kayak.

6*7=$42

Now we add this to the original deposit of $50.
