AnnyKZ [126]

Answer:

Check attached picture ; 75 ; 40 ; 25%

Step-by-step explanation:

s = science fiction movie

H = horror movie

A = adventure movie

From the information given :

n(SnHnA) = 5

n(SnH) only = 15 - 5 = 10

n(SnA) only = 25 - 5 = 20

n(HnA) only = 5 - 5 = 0

n(S) only = 40 - (10+5+20) = 5

n(H) only = 20 - (10+5+0) = 5

n(A) only = 55 - (5 + 20 + 0) = 30

b.) Number of people who saw atleast one movie :

Sum of all numbers in the circles :

(5 + 20 + 5 + 10 + 5 + 30 + 0) = 75

c. How many people saw only one type of movie?

n(S) only + n(H) only + n(A) only

(5 + 5 + 30) = 40

d. What percentage of the people saw none of the three movie types?

Number of people who saw none of the movies:

100 - (Number of people who saw atleast one)

100 - 75 = 25

Hence, percentage who saw none :

(25/ 100) * 100%

(1/4) * 100%

= 25%

Korvikt [17]

MISSING DETAILS

Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?

Answer:

Minutes = 8 minutes

Step-by-step explanation:

Topic: Inequality

Given:

Available Size of water = 17 liters

Increment = 5 liters/minute

Size of water needed = At least 57 liters

Putting the above together, as have

17 + 5m > 57

where m represents total minutes and > represent at least

Solving the Inequality

5m > 57 - 17

5m > 40 ------ Divide through by 5

5m/5 > 40/5

m > 8

So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.

Answer:

Option A. one rectangle and two triangles

Option E. one triangle and one trapezoid

Step-by-step explanation:

step 1

we know that

The area of the polygon can be decomposed into one rectangle and two triangles

see the attached figure N 1

therefore

Te area of the composite figure is equal to the area of one rectangle plus the area of two triangles

so

A=(8)(4)+2[\frac{1}{2}((8)(4)]=32+32=64\ yd^2

step 2

we know that

The area of the polygon can be decomposed into one triangle and one trapezoid

see the attached figure N 2

therefore

Te area of the composite figure is equal to the area of one triangle plus the area of one trapezoid

so

A=\frac{1}{2}(8)(4)+\frac{1}{2}((4+8)(8)=16+48=64\ yd^2
