<h3>The number of seconds in a 40-hour work week can be calculated as follows:</h3>

First we can calculate how many seconds there are in an hour:

Since 1 hour has 60 minutes and each minute has 60 seconds.

Then 1 hour = 60 minutes * 60 seconds/1minute = 3,600 seconds.

Now we have to multiply x 40 to calculate how many seconds there are in 40 hours.

In a 40-hour work week = 40 hours * 3,600 seconds/1hour = 144,000 seconds

Answer : 144,000 seconds there are in a 40-hour work week

Hope this helps!

40hrs*60mins/1hr=2400mins

2400mins*60secs/min=144,000secs

Answer:

Malcolm’s debt-to-income ratio is 0.8125

Step-by-step explanation:

1. When Mrs. Weeks bought all of the baseballs and softballs, she paid

Lostsunrise [7]

Answer:

1) $104

2) 7(28) + 5(20) + c= 4(100)

3) 21 more balls

4) (135/9) + (48/6)

Step-by-step explanation:

The question is incomplete. The total number of balls wasn't stated neither was the cost of each ball.

To determine the answers to the questions above, Let's look at the following question:

Type of Ball:

football basketball baseball softball

Cost per Ball:

$8.00 $9.00 $7.00 $5.00 respectively

Total Number of Balls: 32 36 28 20 respectively

1. When Mrs. Weeks bought all of the baseballs and softballs, she paid for them using four $100.00 bills. How much change did she receive?

2. Write expressions that include parentheses and order of operations to show how to find the answer. Show your work.

3. After school began, Mrs. Weeks realized that she needed more

basketballs and footballs. If she spent $135.00 on basketballs and

$48.00 on footballs, how many more balls did she purchase?

4. Write expressions the include parentheses and order of operations to show how to find the answer. Show your work.

Solution:

Total number of balls = 32+36+28+20 = 116

Cost per ball for football = $8.00

Cost per ball for basketball =$9.00

Cost per ball for baseball =$7.00

Cost per ball for softball =$5.00

1) number of balls for baseball = 28

number of balls for softball = 20

Cost of 28 baseball = 28(7) = $196

Cost of 20 baseball = 20(5) = $100

She paid with = four $100.00 bills

= 4×100 = 400

Change she received = 400-(100+196) = 400-296

= $104

2) 7(28) + 5(20) + c= 4(100)

Where c = the change she collected

196 + 100 +c = 400

296 + c = 400

c = 400-296

c = $104

3) she spent $135.00 on basketballs

$48.00 on footballs

Number of basketballs bought = 135/9

= 15 basketballs

Number of footballs bought = 48/8

= 6 footballs

Total number of balls purchased = 15+6 = 21

She purchased 21 more balls

4) (135/9) + (48/6)

Is (-3, 2) a solution of -4r - 10y< - 9?

Blizzard [7]

Answer:

<em>The point (-3,2) is not a solution of the inequality</em>

Step-by-step explanation:

<u>Inequality</u>

Inequalities relate the left and the right side of an expression with an operator other than the equal sign.

The inequality given in the question is

$-4r - 10y< - 9$

There are many combinations of r and y that make inequality be true. For example, for r=1 and y=1

$-4(1) - 10(1)< - 9$

$-14< - 9$

This relation is true since -14 is less than -9.

Also, there are many combinations that make the given inequality be false.

For example, for r=2 and y=-1

$-4(2) - 10(-1)< - 9$

$-8+10$

$2$

This inequality is false.

Let's test the point (-3,2)

$-4(-3) - 10(2)< - 9$

$12-10$

$2$

Which is false, thus the point (-3,2) is not a solution of the inequality

Given right triangle ABC, what is the value of tan(A)? Five-thirteenths Twelve-thirteenths Twelve-fifths Thirteen-twelfths

WITCHER [35]

Answer:

Twelve-fifths.

Step-by-step explanation:

The diagram is shown below

Given triangle be right angled at $B$ ,

Withe reference to $\angle A$ ,

Its opposite side is $BC=12$ , adjacent side is $AB=5$ and hypotenuse is $AC=13$

We are to find the value of $tan(A)$

We know $tan=\frac{opposite}{adjacent}$

Substituting the above values we get,

$tan(A)= \frac{BC}{AB}=\frac{12}{5}$

So the answer is Twelve-fifths.
