Cole noticed that if he takes the opposite of his age and adds 40 he gets the number 28. how old is Cole?

1 answer:

5 0

-x+40=28
-x=-12 (subtract 40 from both sides)

Divide by -1(in both sides)because you cant have a negative age.
COLE is 12

If 2500 amounted to 3500 in 4 years as simple interest .find the rates at wish the interest was charged

Bad White [126]

Answer:

The interest rate per year is 0.1

Step-by-step explanation:

The equation is A = P(1+rt)

Substitute the numbers

3500 = 2500 (1+4r)

solve for r:

$3500/2500 = 1+4r$

$1.4-1 = 4r$

$0.4 /4 = r$

$r = 0.1$

Select the expression that is equivalent to: 3 root 1089

Delicious77 [7]

Answer:

$3\sqrt{1089}=3\sqrt{3^2(11)^2}$

Step-by-step explanation:

Given : Expression $3\sqrt{1089}$

To find : Select the expression that is equivalent to expression ?

Solution :

Re-write the expression as,

$3\sqrt{1089}=3\sqrt{3\times 3\times 11\times 11}$

$3\sqrt{1089}=3\sqrt{3^2\times 11^2}$

$3\sqrt{1089}=3\sqrt{(3\times 11)^2}$

$3\sqrt{1089}=3\sqrt{(33)^2}$

$3\sqrt{1089}=3\times 33$

$3\sqrt{1089}=99$

The above are the possible equivalent expressions.

Help I don't know how to do geometry

Nana76 [90]

the transformation (x, y) → (x, y- 4) , means the x-coordinate remains unchanged, while the y-coordinate has 4 subtracted from it, for example

the points on the diagram

A(1, 5 ) → A'(1, 5 - 4) → A'(1, 1)

B(4, 5) →B'(4, 5 - 4) → B'(4, 1)

C(4, 3) → C'(4, 3 - 4) → C'(4, - 1)

D(2, 2) → D'(2, 2- 4) → D'(2, - 2)
