If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

**Answer:**

**Step-by-step explanation:**

*Given**,*

No. of days taken by Jenny to read 7 books

= 8

*So**,*

No. of days taken by her to read 1 book

[tex] = \frac{8}{7} [/tex]

*Therefore**,*

No. of days taken by her to read 20 books

[tex] = \frac{8}{7} × 20 [/tex]

[tex] = \frac{160}{7} [/tex]

= 22.85.....

= 23 days (approx. )

*Hence**,*

*Jenny** **will** **take** **23** **days** **to** **read** **20** **books** **(**Ans**)*

Question:-

If Jenny can read 7 books in 8 days, exactly how many days would it take her to read 20 books?

Answer:-22.85714 or 23 days

Explanation:-[tex]GIVEN,[/tex]

Number of books Jenny can read in 8 days = 7

[tex]NOW,[/tex]

Number of days taken by Jenny to read 1 book = [tex] \frac{8}{7} [/tex]

Number of days taken by her to read 20 books =

→ [tex]20 \times \frac{8}{7} [/tex]

→ [tex] \frac{160}{7} [/tex]

→ **22.85714** or **2****3**** ****days**

The population of a city, y, in thousands of people, measured x years after 1800 can be modeled by the regression equation

y = 187.6/1 + 29.4e^-0.03x

Which statement best interprets a value in the equation?

The city population in 1800 was 187,600 people.

The city population grows by 29,400 people per year.

The limiting value of the city population is 29,400 people.

The limiting value of the city population is 187,600 people.

**Answer:**

D. The limiting value of the city population is 187,600 people.

**Step-by-step explanation:**

**I'm honestly not sure, but it's based on the 187.6 on top of the equation. Correct on Edge 2021**

Question 34, the answer is C. I just need the working. Tysm

**Answer:**

C

**Step-by-step explanation:**

∠ ABC = 90° ( angle in a semicircle )

Using the cosine ratio in right triangle ABC and the exact value

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

cos30° = [tex]\frac{adjacent }{hypotenuse}[/tex] = [tex]\frac{AB}{AC}[/tex] = [tex]\frac{10}{AC}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

AC × [tex]\sqrt{3}[/tex] = 20 ( divide both sides by [tex]\sqrt{3}[/tex] )

AC = [tex]\frac{20}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] ( rationalising denominator )

AC = [tex]\frac{20\sqrt{3} }{3}[/tex]

radius AO = [tex]\frac{1}{2}[/tex] AC = [tex]\frac{1}{2}[/tex] × [tex]\frac{20\sqrt{3} }{3}[/tex] = [tex]\frac{10\sqrt{3} }{3}[/tex] → C

you are going to wash a large glass window in a shape of a trapezoid. The lenghts of the bases of the window are 10 feet and 14 feet. the height is 8 feet. you can wash 6 square feet of the window in 1 minute. how long will it take you to wash the entire window

**Answer:**

16 minutes

**Step-by-step explanation:**

First we are going to want to find the area of the window. We then divide that by the amount of area you can wash per minute ( 6 square feet )

So first lets find the area.

We are told that the window is in a shape of a trapezoid.

The area of a trapezoid can be calculated using the formula A = [tex]\frac{a+b}{2} h[/tex]

Where a and b are the base lengths and h is the height

We are told that the length of the bases are 10 ft and 14ft so a and b = 10 and 14. We are also told that the window has a height of 8 so h = 8 .

We then plug these numbers into the formula to find the area

Recall formula: [tex]A=\frac{a+b}{2} h[/tex]

a = 10 , b = 14 and h = 8

plug in these values into formula

[tex]A=\frac{10+14}{2} 8[/tex]

add 10 and 14 to get 24

[tex]A=\frac{24}{2} 8[/tex]

simplify fraction : 24 / 2 = 12

[tex]A=(12)(8)[/tex]

multiply 12 and 8 to get 96.

A = 96 square feet.

To find how long it would take to wash the window we divide the total area of the window by the amount of area that can be washed per minute

Total area of window = 96

Area that can be washed per minute = 6

Time it would take to wash the whole window = 96 / 6 = 16 minutes

m11=54°

m8=117°

m7=63°

**Step-by-step explanation:**

a) m2=m12 (corresponding angles)

m12=126°

180=m12+m11 (supplementary angles equal 180)

180=126+m11

m11=54°

b) m14=m8. (corresponding angles)

m8=117°

C) m7=180-m8 (supplementary angles equal 180)

m7=180-117

m7=63°

**Answer:**

In short, Your Answer would be either 1 or 7

**Step-by-step explanation:**

|4x + 12| = 16

As it is in modulus function, it could be either +ve or -ve

4x+12 = 16 OR 4x - 12 = 16

4x = 16-12 OR 4x = 16 + 12

4x = 4 OR 4x = 28

x = 4/4 OR x = 28/4
