4/5 = 28/x


You need to multiply 4 by how many times to get 28?


4.y = 28

y = 28/4

y = 7


So, you need to multiply 5 by 7 to know x.


x = 5.7

x = 35


4/5 = 28/35

If \frac{4}{5} = \frac{28}{x}, we need to find out what form of one we have to multiply one fraction to get the other fraction. Since we only have the numerator of both fractions, we need to divide each of the numerators to find out what we need to multiply the denominator we know to get x. We can do this because multiplying by a form of one (e.g. 3/3) doesn't change the value of a fraction or expression. 28/4 is 7, so we have to multiply the denominator 5 by 7. Since 7 * 5 is 35, \frac{4}{5} = \frac{28}{35}

$1,000, 7% , 2years
Simora [160]

Answer:

$1,140, or $1,144.9

Step-by-step explanation:

70 is 7% of 1,000

70 x 2 = 140

140 + 1,000 = 1,140

Or, if you mean 7% compounded annually then....

1,070 after first year.

7% of 1,070 = 74.9

74.9 + 1,070 = 1,144.9

Which series of transformations shows that rectangle A is similar to rectangle B?
Brut [27]

Answer:

D. Dilate rectangle A by a scale factor of 3 with the center of dilation at the origin and rotate it 90° clockwise about the origin.

Step-by-step explanation:

The coordinates of triangle A are (-2,1) , (1,1), (1,-1) and (-2, -1) while that of triangle B are (-3, 6), (3, 6), (3, -3) and (-3, 3).

To transform A to be we need a combination of two transformations, and that is dilation and rotation.

If A is dilated by a scale factor three through the origin as the center of dilation and then rotated through 90° clockwise with the origin as the center of origin, then rectangle B will be obtained.
