Jackson's rectangular bedroom has an area of 80 square feet. The area of his bedroom is 10 times that of his rectangular closet. If the closet is 2 feet wide, what is its length? BE SURE TO ADD A LABEL TO YOUR ANSWER.

Answers

Answer 1

Answer:

Length of the rectangular closet = 4 feet

Step-by-step explanation:

Area of his bedroom = 80 square feet.

The area of his bedroom = 10 times that of his rectangular closet.

Let x = area of his rectangular closet.

80 = 10 * x

80 = 10x

x = 80/10

= 8

x = 8 square feet

If the closet is 2 feet wide, what is its length?

Area of the rectangular closet = length × width

Let y = Length of the rectangular closet

8 Square feet = y feet × 2 feet

8 = 2y

y = 8/2

= 4

y = 4 feet

Length of the rectangular closet = 4 feet

Sebastian drove for 2.2 hours at an average rate of 43.5 miles per hour. He calculates that he drove 95.7 miles. He knows the answer should be near 80, because 40 times 2 is 80. Which best explains Sebastian’s actual solution?
The actual product is reasonable because it is near 80 but greater than 80. Both factors were rounded down, making the estimate lower than the actual product.

Solve 3q - 5 = 13 for q.

Answers

Answer:

[tex]q = 6[/tex]

⇒ Step-by-step explanation:

Lets solve!

[tex]3q -5 = 13[/tex]

⇒ First we add 5 to both sides.

[tex]3q -5 = 13[/tex]

   [tex]+ 5[/tex]     [tex]+ 5[/tex]

    [tex]3q = 18[/tex]

⇒ Next we divide both sides by 3.

 [tex]\frac{3q}{3} = \frac{18}{3}[/tex]

[tex]q = 6[/tex]

⇒Woohoo! Brainliest Appreciated! Hope I helped!

Answer:

q = 6

Step-by-step explanation:

To solve for q, isolate the variable.

3q - 5 = 13

Move -5 to the right side and perform the inverse operation. Since you were subtracting on the left, add on the right.

3q = 13 + 5

3q = 18

The last step is to isolate the variable by dividing 3 by 18. The reason you divide on the right is because you were multiplying on the left, and you need to perform the inverse operation.

q = [tex]\frac{18}{3}[/tex]

q = 6

Hours customers get per dollar = ?

Solution:

The number of hours customer gets per dollar is;

      Number of hrs/dollar = [tex]\frac{time duration }{cost}[/tex]

    Number of hrs/dollar  = [tex]\frac{6hrs}{31}[/tex]

A rectangular painting has a diagonal measure of 17 inches and an area of 120 square inches. Use the formula for the area of a rectangle and the Pythagorean Theorem to find the length and width of the painting.

Answers

Answer:

Length = 8 inches

Width = 15 inches

Step-by-step explanation:

A rectangular painting has a diagonal measure of 17 inches and an area of 120 square inches. Use the formula for the area of a rectangle and the Pythagorean Theorem to find the length and width of the painting.

Let:

a = length of painting

b = width of painting

Area of painting = 120 = ab

Pythagorean Theorem says

a² + b² = Diagonal²

a² + b²= 17²

[120 =ab means b= 120/a]

a² + (120/a)² = 17²

Multiply through by a²

a⁴ + 14400 = 289

z² + 14400 = 289z [for now, substitute z for a²]

z² - 289z + 14400 = 0

z² - 64z - 225z + 14400 = 0

z(z - 64) -225(z - 64) = 0

(z - 64)(z - 225) = 0

z - 64 = 0

z = 64

z - 225 = 0

z = 225

Note that:

z for a²

Hence:

a² = 64

a = √64

a = 8 inches

The same applies for b

b² = 225

b = √225

b = 15 inches

a rectangular box of mass 40 kg has a length of 5m and a width of 8m and a height of 3 m find its density in kg/m3 ​

Answers

Answer:

1/3 kg/m3

Step-by-step explanation:

density= mass/volume

mass=40 kg

volume=5m×8m×3m=120m³

density=40kg/120m³=1/3 kg/m³

Answer:

1/3 kg per cubic m or 0.33kg per cubic m

Step-by-step explanation:

density = mass

                volume

=     40kg          =     40kg

5m x 8m x 3m  =    120cubic metres

= 1/3 kg per cubic m or 0.33 kg per cubic m

Answers

Answer:

∠PSR = 113°

Step-by-step explanation:

Two angles in a parallelogram that are next to each other are supplementary. That means that they add up to 180°, so 7x-13+4x-5 = 180. Solve for x.

7x-13+4x-5=180

        11x-18=180

            11x=198

               x=18

Now plug x back into the angle that opposite from the one you are looking for (they are equal)

7(18)-13 = ∠PSR

 126-13 = ∠PSR

       113 = ∠PSR

a university department administers a survey regardring student satisfaction based on the survey results the department provides a confidence interval estimate of 60% to 80% for student satisfaction if the department wishes to construct a confidence interval the more accurate represents the proportion of a student satisfaction how should the design be altered

Answers

Answer:

Change the confidence interval.

Step-by-step explanation:

The confidence interval should be altered . If a 95 % or 90% confidence interval is set then better results can be obtained for student satisfaction.

A 90 or 95  or 99 percent confidence interval will show  a greater range of the data that lies within or without the given criteria.

95 % confidence interval does not mean that the probability is 95% . It means that we are 95% of the data lies  or does not lie within the specific range.

This gives better results as compared to 60- 80 % confidence intervals.

If 95% of the students are satisfied as compared to 60% or 80% , this shows more accuracy.
