Answer 1

Answer:

7 books

$27

Step-by-step explanation:

3x + 6= 5x - 8

3x - 5x = -14

-2x= -14

x= 7 books

he has (3×7)+6= $27

Answer 2

Let comics be c and mystery be m

Cost be y

c=m

The equations are

y=3m+6y=5m-8

Solve for m

3m+6=5m-82m=18m=7books

He has

7(3)+621+6$27

Question 32 The numbers represented by variables a and c, on the number line, are integers. if c > b > a, under which of the following conditions could the expression b < -1 be true? when a = -4 and c = 0 B when a = - 1 and c = 3 OO C when a O and c 8 when a 1 and c = 2​

Answers

The number line inequality will be true for the following condition given in this problem:

When a = 0 and c = -8.

How are real numbers represented on a number line?

On a number line, real numbers increase from left to right, meaning that:

Large negative numbers come before small negative numbers, which come before small positive numbers, and finally, come the large positive numbers.

For this problem, the inequality is:

c > b > a.

Which means that:

c is to the left of b.b is to the left of a.

We have that b < -1, hence:

c < -1 (can be -2, -3, -4, and so on...).a > -1 (can be 0, 1, 2, 3, and so on)...

Then the conditions that make the statement b < -1 true are given as follows:

When a = 0 and c = -8.

Which is greater 1/12 pound or 2 ounces? Explain

Answers

Answer: 2 ounces

Step-by-step explanation:

1 pound = 16 ounces

1/12= 0.0833333

if you multiply 0.0833333 by 16, youll get 1.3333

therefore for 1/12 pounds you have 1.333 ounces

and it’s obvious that 2 ounces is greater than 1.3333 ounces

The greater is the 2 ounces.

We have to determmine which one is grater from 1/12 and 2.

What is the value of one pounds in ounces?

1 pound = 16 ounces

We have 1/12= 0.0833333.

Now  multiply 0.0833333 by 16, we get 1.3333.

Therefore for 1/12 pounds you have 1.333 ounces.

Therefore 2 ounces is greater than 1.3333 ounces.

Given circle Q with a measure of SR= 120° and a radius of 9 feet, as shown below.
Determine the arc length of SR. Use mathematics to explain how you determined your answer
Has photo ❤️

Answers

Answer:

18.84feet

Step-by-step explanation:

Length of an arc = rtheta

radius r = 9feet

theta = SR= 120°

Convert theta to radians

theta = 120π/180

theta= 2π/3

Length of the arc = 9 * 2π/3

L = 18π/3

L = 6π

L = 6(3.14)

L = 18.84feet

Hence the length of the arc is 18.84feet

Matti built a greenhouse in his backyard as shown below. A triangular prism with a rectangular base. The prism has a base of 7 feet by 15 feet. The height is 7 feet. The side lengths are 7.8 feet. How much cubic space is in Matti's greenhouse? 191.1 ft 367.5 ft 382.2 ft 735.0 ft

Answers

Answer:

Capacity of Matti's green house = 367.5 cubic feet

Step-by-step explanation:

Given:

Base Width and Length = 7 feet by 15 feet

Height of prism = 7 feet

Find:

Capacity of Matti's green house

Computation:

Capacity of Matti's green house = Volume of rectangular base[triangular prism]

Volume of rectangular base[triangular prism] = Area of triangular base x Height

Capacity of Matti's green house = [(1/2)(7)(7)][15]

Capacity of Matti's green house = [(1/2)(49)][15]

Capacity of Matti's green house = [(24.5)][15]

Capacity of Matti's green house = 367.5 cubic feet

A 17-foot ladder is leaning against a building. The base of the ladder is 8 feet
from the base of the building. The side of the building and the ground form
a right angle as shown.

Enter the distance between the ground and the top of the ladder, x, in feet.

Answers

Answer:

Pythagorean theorem:

x^2 = 17^2 - 8^2

x^2 = 225

x = sqrt(225) = 15

The distance is 15 ft

Answer:

Solution given:

base=8ft

hypotenuse=17ft

perpendicular=?

By using Pythagoras law

hypotenuse ²=perpendicular ²+base²

17²=perpendicular ²+8²

perpendicular ²=17²-8²

perpendicular=[tex]\sqrt{225}=15[/tex]

the distance between the ground and the top of the ladder, x is 15ft.

Find the value of y !!

Answers

Answer:

y ≈18.8

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

y^2 +18^2 = 26^2

y^2 +324=676

y^2 = 676-324

y^2 =352

Taking the square root of each side

sqrt(y^2) = sqrt(352)

y is approximately 18.76

y ≈18.8

If your Gross Pay for a week at work is $340, and you have to pay 23% in taxes, what is your Net Pay (what you take home)?

Answers

Answer:

$261.80 Net pay

Step-by-step explanation:

340 x 0.23 =   $78.20 in taxes

$340 - $78.20 =  $261.80 Net pay

Answer:

$261.8 Is how much you take home.

Step-by-step explanation:

(* is multiply)

In order to find the percentage of a value, you multiply the value by the percent. Think of 100% as a scale of 1 to 0.00, since 100% of something has all of it's value, so 50% would be 0.5

23% of 340 is 78.2 ( 340 * 0.23)

Subtract 340 by 78.2, and you get your net pay, 261.8

Another way to do this is subtract 100% by 23%.

so 1 - 0.23= 0.77, which is how much percent of that pay you get to keep

so 340 * 0.77 = 261.8

The mean area µ of the several thousand apartments in a new development is advertised to be 1250 square feet. A tenant group thinks that the apartments are smaller than advertised. They hire an engineer to measure a sample of apartments to test their suspicion. The appropriate null and alternative hypotheses, H0 and Ha, for this test are

Answers

Answer:

The appropriate null hypothesis is [tex]H_0: \mu = 1250[/tex]

The appropriate alternate hypothesis is [tex]H_a: \mu < 1250[/tex]

Step-by-step explanation:

At the null hypothesis, we test if the mean area is the advertised area of 1250 square feet, that is:

[tex]H_0: \mu = 1250[/tex]

A tenant group thinks that the apartments are smaller than advertised.

Smaller, thus, at the alternate hypothesis, we test if the mean area is less than the advertised area of 1250 square feet, that is:

[tex]H_a: \mu < 1250[/tex]
