Please help me! I'll give brainliest to the best answer! (Sorry its sideways.)​

Answer:

If it is direct proportionality, then y = kx where k is a constant.  Use the given information to find k:

8 = k(12) ⇒ k = 8/12 = 2/3

y = (2/3) x

For y = 12,

12 = (2/3) x ⇒ x = (3/2)*12 = 18

x = 18 when y = 12

I hope this helps a little bit.

Answer:

y=(x+3)^2 has a vertex at (-3,0), while y=x^2 + 3 has a vertex at (0,3)

Answer:

its an acute angle

Step-by-step explanation:

its an acute angle be cause its small than a right angle

Answer:

angle AED =  70 degrees

angle x = 10 degrees

Step-by-step explanation:

since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees

since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees

minor arc BD = 360 - 220 - 80 = 60 degrees

arc AB + arc BD = arc ABD

arc ABD = 80 + 60 = 140 degrees

angle AED = 1/2 (140) = 70 degrees

angle EAD = angle AED because isosceles

arc ED = 2(70) = 140 degrees

arc AE = arc AED - arc ED = 80 degrees

angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees

Answer:

9/4 or 2 and 1/4 pounds

Step-by-step explanation:

Convert 15 and 3/4 into an improper fraction

15*4+3 = 63

63/4

63/4 ÷ 7

9/4

Thus, each pack weighs 9/4 pounds

Answer:

2 1/4 pounds each

Step-by-step explanation:

Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)

and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4

Answer:

They are similar because they both have like terms in parenthesis.

Step-by-step explanation:

As long as you have like terms, the equation is the same. You never have to worry about the number before the variable being the same. As long as the variable is the same, you have like terms and that is like terms in the equation. TO SUM IT UP: They both have like terms and that is why they are similar.

Step-by-step explanation:

Answer: 24%

Step-by-step explanation:

Since we are informed that the Girl Scout Troop started with 25 girls and at the end of the year party there were 31 girls. The percentage change will be:

= (31 - 25) / 25 × 100

= 6/25 × 100

= 24%

The error that Gabby made was that she used 31 as the base. This is expressed below:

= 31 - 25) / 31 × 100

= 6/31 × 100

= 19.4%

Answer: 12x-8y

Step-by-step explanation:

Answer:

2

Step-by-step explanation:

y = mx + b

y = 2x + 3

m is the slope. So of we look in the equation 2 is in the m place so 2 is the slope. Hope this helps, thank you :) !!

Answer:

m<E = [tex]77^{o}[/tex]

Step-by-step explanation:

From the diagram, ΔACE and ΔBDE are similar. So that comparing its angles, we have;

(8x + 4) = (9x - 5)

8x + 4 = 9x - 5

5 + 4 = 9x - 8x

x = 9

Thus,

(8x + 4) = 8(9) + 4 = 76

(9x - 5) = 9(9) - 5 = 76

3x = 3(9) = 27

From ΔACE,

3x + (8x + 4) + m<E = 180 (sum of angles in a triangle)

27 + 76 + m<E = 180

m<E = 180 - 103

m<E = [tex]77^{o}[/tex]

Answer:

Step-by-step explanation:

Scale factor  = 1 : 7

a)Let the length of the house in the scale drawing = x

1:7 :: x : 21

Product of means = Product of extremes

 7*x = 1* 21

     x = [tex]\frac{1*21}{7}[/tex]

     x = 3

Length of the house in the scale drawing = 3 in

b) Height of the real house =y

1 : 7 :: 4 : y

Product of extremes = product of means

1 * y = 7*4

   y = 7*4

   y = 28

Height of real house = 28 feet

Answer:

70 ft

WHO WANTS SOME BONELESS PIZZA ??

Answer:

$498.75

Step-by-step explanation:

Why it would be $498.75 is 500 - 25 is 475 then if you do 5% of 475 you get 23.75 and you will add that to the 475 and you will get $498.75.

Answer:

27 pages

Step-by-step explanation:

Since you read 3 pages on Monday and you read 3 times that number on Tuesday, the equation should be 3*3 to equal 9. Then, since you read 9 pages on Tuesday and 3 times that number on Wednesday, the equation should be 9*3 to equal 27 pages. So, on Wednesday, you read 27 pages in total.

Answer:

27 pages

Step-by-step explanation:

Monday=3 pages

Tuesday=3 pages × 3

=9 pages

Wednesday=9 pages × 3

=27 pages

Answer:

$16

Step-by-step explanation:

Answer:

Estimate: $16

Exact amount: $15.98

Step-by-step explanation:

To find the estimate amount of money she has left, we will add everything up and subtract it from $45.12.

$7.89 + $21.25 = $29.14

$45.12 - $29.14 = 15.98

Now lets round your answer to $16.  Therefore, the estimated amount that she has left is $16.   And based on the calculations above, we can see that the exact amount of money she has left is $15.98.

  C. The horizontal cross-sections of the pyramid and cone at the same height must have the same area

Step-by-step explanation:

Cavalieri's principle says that solids with corresponding cross sections of the same area will have the same volume. Statement C is the converse of this principle.
