No, 17.39% were raised in Minnesota.

You can find this by dividing 40,000,000 by 230,000,000 and then converting to a percent by multiplying by 100.

40,000,000/230,000,000=.1739
.1739 x 100= 17.39%

julsineya [31]

Answer:

(C)81

Step-by-step explanation:

Total Number of Students =300

Percentage who had cats, n(C) = 40%

Percentage who had both cats and dogs , n(C \cap D) = 12%

Percentage who had neither cats nor dogs, n(C \cup D)' =45%

Now:

Universal Set, U = n(C)+n(D)-n(C \cap D)+n(C \cup D)'

100 = 40 + n(D)-12+45\\n(D)=100-73\\$Percentage of those who own dogs =27\%

Therefore:

Number of Students who had dogs

=27% of 300

=81

Complete the equation of the line through (-8-2) and (-4-6)
Kisachek [45]

Answer:

Step-by-step explanation:

since you are given two points use the point- slope formula and the slope formula

y-y1 = m( x -x1)   and  m = y2 -y1 / x2 - x1        

find the slope m, 1st

p1 = (x1,y1)  given (-8,-2)

p2 = (x2,y2) given (-4,-6)

m = -6-(-2) / -4-(-8)

m = -6+2 / -4+8

m = -4 / 4

m = -1  :)

now use the slope you just found and the point-slope with either given point.. pick one.. which ever seems easier... they seem about the same to me

y - (-8) = -1(x-(-2))

y+8 = -1(x+2)

y+8 = -x-2

y = -x-2-8

y= -x-10

and your done :)

Linear system please help 60 points * please please please help will give brainlist
bearhunter [10]

Answer:

1. a. b = - 8

b. x = 8

c. x = 11

d. x = 5

2. 12 soccer balls and 8 basketballs can be purchased.

Step by step explanation

a. - 14 + 6b + 7 - 2b = 1 + 5b

Calculate the sum

- 7 + 6b - 2b = 1 + 5b

Collect like terms

7 + 4b = 1 + 5b

Move variable to L.H.S and change it's sign

Similarly, Move constant to R.H.S and change its sign

4b - 5b = 1 + 7

Collect like terms

- b = 8

Change the signs on both sides of the equation

b =  - 8

-----------------------------------------------------------------

b. \frac{5x   + 10}{ - 6}  =  - 5

Apply cross product property

5x + 10 =  - 5 \times  ( - 6)

Multiply the numbers

5x + 10 = 30

Move constant to R.H.S and change its sign

5x = 30 - 10

Calculate the difference

5x = 20

Divide both sides of the equation by 5

\frac{5x}{5}   = \frac{20}{5}

Calculate

x = 4

----------------------------------------------------------------

c. - 15 =  \frac{ - 8x - 17}{7}

Apply cross product property

- 15 \times 7 =  - 8x - 17

Multiply the numbers

- 105 =  - 8x - 17

Swap the sides of the equation

- 8x - 17 =  - 105

Move constant to R.H.S and change its sign

- 8x =  - 105 + 17

Calculate

- 8x =  - 88

Change the signs on both sides of the equation

8x = 88

Divide both sides of the equation by 8

\frac{8x}{8}  =  \frac{88}{8}

Calculate

x = 11

------------------------------------------------------------------

D. 5 = 6x + 5(x - 10)

Distribute 5 through the parentheses

5 = 6x + 5x - 50

Collect like terms

5 = 11x - 50

Swap both sides of the equation

11x - 50 = 5

Move constant to R.H.S and change its sign

11x = 5 + 50

Calculate the sum

11x = 55

Divide both sides of the equation by 11

\frac{11x}{11}  =  \frac{55}{11}

Calculate

x = 5

------------------------------------------------------------------

2.

Solution,

No.of students in soccer = x

No.of students in basketball = y

Total no.of students = 20

i.e x + y = 20 → equation ( i )

Cost of soccer ball = $ 7

Cost of basketball = $ 10

Total budget = $ 164

i.e 7x + 10 y = 165 → equation ( ii )

In equation ( i ),

x + y = 20

Move 'y' to R.H.S and change its sign

x = 20 - y

Put the value of x in equation ( i )

7(20 - y) + 10y = 164

140 - 7y + 10y = 164

3y = 164 - 140

3y = 24

y =  \frac{24}{3}

y = 8

Now, put the value of y in equation ( i ) ,

x + y = 20

x + 8 = 20

x = 20 - 8

x = 12

Hence, 12 soccer balls and 8 basketballs can be purchased.

Hope this helps...

Best regards!!
