Answer: Using operations with fractions, the diver's final location is:

- 60 3/4 meters relative to the surface of the water (60 3/4 meters below the surface of the water).

Solution:

Initial location: -50 1/4 meters

He descends another 10 1/2 meters: -10 1/2 meters

Final location = Initial location - 10 1/2 meters

Final location = - 50 1/4 meters - 10 1/2 meters

Final location = - (50+10) (1/4+1/2) meters

Final location = - 60 [(1)(1)+2(1)]/4 meters

Final location = - 60 (1+2)/4 meters

Final location = - 60 3/4 meters

Wyatt should charge $9.26 before 8% sales tax if he does not want customers to pay more than $10.00

They will actually be charged $10 exactly.

9.26*.08= .74

.74+9.26= 10

Which inequality describes all the solutions to 5(3 − x) < −2x + 6?

Marrrta [24]

Given:

The inequality is

$5(3-x)$

To find:

The inequality that solution describes all the solutions to the given inequality.

Solution:

We have,

$5(3-x)$

Using distributive property, we get

$5(3)+5(-x)$

$15-5x$

$15-6$

$9$

Divide both sides by 3.

$\dfrac{9}{3}$

$3$

It can be written as

$x>3$

Therefore, the value of x is greater than 3. So, the required inequality is either $x>3$ or $3$ .

What does h(3.2) represent?

marshall27 [118]

Answer:

the height of the rock 3.2 seconds after it is propelled

Step-by-step explanation:

<u><em>The complete question is</em></u>

The function h(t) = –16t2 + 28t + 500 represents the height of a rock t seconds after it is propelled by a slingshot

Let

t------> the time in seconds

h----> the the height of a rock after it is propelled by a slingshot in meters

we know that

$h(t)=-16t^{2} +28t+500$

For $x=3.2\ sec$

Find the value of h(t)

$h(3.2)=-16(3.2)^{2} +28(3.2)+500=425.76\ meters$

therefore

h(3.2) represent the height of the rock $3.2$ seconds after it is propelled

The scale factor for two similar rectangles is 4. If the area of the smaller rectangle 7m^2, what is the area of the larger rect

nydimaria [60]

Answer:

A. 112 m^2

Step-by-step explanation:

If the scale factor is 4, the area of the larger figure is 4^2 times that of the smaller one.

... (7 m^2)·4^2 = 112 m^2

_____

The scale factor for area is the square of the scale factor for linear dimensions. When we talk about a scale factor without qualification, we mean the scale factor for linear dimensions.
