ra1l [238]

Answer:

$ 154

Step-by-step explanation

Let the value of suitcase=x

x × 4.5% = 6.93 (converted the question into equation)

x × $\frac{4.5}{100}$ = 6.93 (converted the percentage into fraction)

x = 6.93 x $\frac{100}{4.5}$ (took reciprocal of 4.5/100 after moving it to the other side of the equation)

x = $\frac{693}{4.5}$ (multiplied the values)

x = 154 $ (simplified the fraction)

make it the brainliest and get 20 years of luck : )

A ball is dropped from a height of 64 feet. Its height, in feet, can be modeled by the function h(t) = -167 + 64, where t is the

Oliga [24]

Answer:

Step-by-step explanation:

Known facts:

the ball dropped from a height of 64 feet
function $h(t) = -16t^{2} + 64$

First question:

the ball hits the ground when h(t) = 0, thus we get the equation

$-16t^{2} +64 = 0\\16t^{2} = 64\\t^{2} =4\\t = 2$

So the ball hits the ground in 2s

Second question

to find how long it takes the ball to fall 36 feet, we must set h(t) = 64 - 36 = 28

$-16t^{2} +64 = 28\\16t^{2} = 36\\t = \frac{6}{4} =1.5s$

So the ball hits the ground in 1.5s

Hope that helps!

What is the probability that a family of 4 children will have all girls?

Alex73 [517]

Since as of now we're saying that the probability of having a girl is 1/2, we can say:
1/2 * 1/2 * 1/2 * 1/2, because then you're saying a one half chance of having a girl times another one half chance of having a girl, etc.
That ends up to be 1/16.
