A student earns $7.50 per hour at her part-time job. She wants to earn at least $200.Enter an inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.

Enter the least whole number of hours the student needs to work in order to earn at least $200

Answers

Answer: 7.50 h ≥200

She needs to work 27 hours to earn at least $200.

Step-by-step explanation:

Hi, to write the inequality we have to analyze the information given:

Earnings per hour : $7.50

Hours : h

She wants to earn at least $200.

So, she earns $7.50 per hour, the expression that represents the statement is $7.50h.

She wants to earn at least $200, "at least" means more or equal (≥200).

Mathematically speaking:

$7.50 h ≥200

This is the inequality that represents all of the possible numbers of hours (h) the student could work to meet her goal.

For the second part we simply solve the inequation:

7.50 h ≥200

h ≥200/7.50

h ≥ 26.67

Rounded to the nearest whole number:

h ≥ 27

She needs to work 27 hours to earn at least $200.

Total amount of cash the student earns per hour is $7.5, let the time taken to earn $200 be h, thus the inequality representing this will be:
7.5h≤200
thus
h≤80/3
writing in whole numbers we shall have:
h≤27

If you grow 523 eggplants and sell 378, how many do you have left?

Answers

145, you subtract the total number with how many you sold
523-378=145

If you grow 523 eggplants and sell 378 of them then you will have 145 left.

523 - 378 = 145

What is the PE of a 10 kg box that drops 10 meters?

Answers

Change of PE over a height of 10m = M G H = (10) (9.8) (10) = 980 joules.

When the box hits the bottom, it has 980 joules less PE than it had
before it started dropping.

(As well as 980 joules more kinetic energy.)

P.E = mgh
M= MASS
G= ACCELERATION DUE TO GRAVITY
H = HEIGHT
P.E= 10 * 10 * 10
P.E = 1000J

Which property of real numbers is shown below? -6(4x + 5) = -24x - 30 associative property of addition commutative property of multiplication distributive property inverse property of addition

Answers

The Distributiveproperty of addition over multiplication is shown in the expression -6(4x + 5) = -24x - 30.

Given,

-6(4x + 5) = -24x - 30

We need to find out which property is applied in the given expression.

What are the properties of algebra?

Some of the properties are:

- Commutativeproperty of

Addition - a + b = b + a

Multiplication - a x b = b x a

- Associativeproperty of

Addition - (a + b) + c = a + (b + c)

Multiplication - (a x b) x c = a x (b x c)

-Distributiveproperty of addition over multiplication

a x (b + c) = a x b + a x c

a + b x c = (a x c) + (b x c)

- Inverseproperty

a + -a = 0

Inverse property of a is -a.

We have,

-6 ( 4x + 5 )

= (- 6) x 4x + ( - 6 ) x 5

= -24x - 30

If a = -6, b = 4x and c = 5

We have,

= a x ( b + c )

= a x b + a x c

We see that Distributiveproperty of addition over multiplication is applied here.

Thus the Distributiveproperty of addition over multiplication is shown in the expression -6(4x + 5) = -24x - 30.

This would be the distributive property!!

The distributive property lets you multiply a sum by multiplying each addend separately and then add the products

hope this helps!
