Answers

Answer:

Step-by-step explanation:

You can automatically rule out A and C because they're too big of a fraction. The common denominator between 8 and 9 is 72, and if you covert the fractions to [tex]\frac{32}{72}[/tex]([tex]\frac{4}{9}[/tex]) it's larger than [tex]\frac{9}{72}[/tex]([tex]\frac{1}{8}[/tex])

Juan travels 16 miles per hours for 7 hours. Find the distance traveled in miles

Answers

Answer:

112 Miles

Step-by-step explanation:

16 (per hour) for 7 hours

16x7 (we Multiple the speed [since its per hour] the number of hours.)

112

Given:

Speed of Juan = 16 mph

Time traveled = 7 hours

To find:

Total distance traveled

Steps:

Total distance traveled is equal to speed into time traveled,

Total distance = Speed × time traveled

Total distance = 16 × 7

Total distance = 112 miles

Therefore Juan traveled 112 miles in 7 hours at the speed of 16 mph

Please help me Algebra 1

Answers

Answer:

a. [tex]\sqrt{x^n}[/tex] = [tex]x^\frac{n}{2}[/tex]

b. [tex]\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}[/tex]

Step-by-step explanation:

a) When n is even, then it is divisible by 2. Because of this, you can write:

[tex]\sqrt{x^n} = (x^n)^\frac{1}{2}[/tex][tex]\sqrt{x^n} = x^\frac{n}{2}[/tex]

b) When n is odd, then n - 1 is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:

[tex]\sqrt{x^n} = (x^n^-^1^+^1) ^\frac{1}{2}[/tex][tex]\sqrt{x^n} = (x^n^-^1[/tex] × [tex]x)^\frac{1}{2}[/tex][tex]\sqrt{x^n} = x^\frac{(n-1)}{2}[/tex] × [tex]x^\frac{1}{2}[/tex][tex]\sqrt{x^n} = x^\frac{(n-1)}{2}\sqrt{x}[/tex]

Find the area of the composite shape if the trapezoid has a height of 7 in. Use pi = 3.14

A.80.76 sq in
B.64.13 sq in
C.66.63 sq in
D.26.25 sq in

Answers

Answer:

Step-by-step explanation:

The composite shape is a trapezoid + semi circle

The formula for area of a trapezoid is:

1/2(b1+b2)h

Where b1 is base 1

Where b2 is base 2

Where h is height

B1 is 6

B2 is 9

h is 7

1/2 (6 + 9) 7

1/2 (15) 7

7.5 x 7

= 52.5

The Semi circle formula is:

pi x r^2 (all divided by 2)

Where pi is 3.14

Where r is radius

The radius is 1/2 the diameter

6/2 = 3

3.14 x 3^2 /2

3.14 x 9 / 2

28.26 / 2

= 14.13

Trapezoid + Semi Circle

52.5 + 14.13

= 66.63 sq in.

A girl read a book that had 1,159 pages. She read 72 pages on the first day. She then read 40 pages per day until she finished the book. Which equation could be used to find the number of days, d, it took her to read the book?

Answers

Answer:

1,159=40d+72

Answer:

(1159-72)÷40= 27 it would take her 27 days

Step-by-step explanation:

if she initially read 72 you would subtract that from the original number of pages she had to read, then divide the number that's left with how many pages she read a day after that which is 40. to get a total of 27 days to read
