Does anyone know the answer?

Helen [10]

The answer would be 60, if you add 13,15, and 12 up you get 40. Those numbers would be considered 2/3 of all the marbles. Divide 40 by 2 to get how many marbles is 1/3. You would get 20 being a third if the marbles. Add that to the original 40 and you’ll get a total of 60.

the length and width of a rectangle are consecutive integers. If the area of the rectangle is 90cm^2 , what is the primeter of t

Genrish500 [490]

Answer:

Step-by-step explanation:

Let length and width of a rectangle be x, x+1

Area = 90 sq.cm

length * width = 90

x * (x + 1) = 90

x² + x = 90

x² + x - 90 = 0

x² + 10x - 9x - 9 * 10 = 0

x ( x + 10 ) - 9 (x + 10 ) = 0

(x + 10 ) (x - 9) = 0

x + 10 = 0 or x - 9 = 0

x = -10 { impossible . as length cannot be negative} ;

x = 9

Length = 9 , width = 10

If triangle XYZ’s points are X (-2, 1), Y (-4,-3), and Z (0,-2) what are the new coordinates of X’, Y’, and Z’ if the triangle i

8090 [49]

Answer:

The coordinates of image are X'(-3,4), Y'(-5,0) and Z'(-1,1).

Step-by-step explanation:

The vertices of triangle XYZ are X(-2,1), Y(-4,-3) and Z(0,-2).

It is given that the triangle translated by rule

$(x,y)\rightarrow (x-1,y+3)$

The coordinates of image of XYZ are

$X(-2,1)\rightarrow X'(-2-1,1+3)$

$X(-2,1)\rightarrow X'(-3,4)$

$Y(-4,-3)\rightarrow Y'(-4-1,-3+3)$

$Y(-4,-3)\rightarrow Y'(-5,0)$

$Z(0,-2)\rightarrow Z'(0-1,-2+3)$

$Z(0,-2)\rightarrow Z'(-1,1)$

Therefore coordinates of image are X'(-3,4), Y'(-5,0) and Z'(-1,1).

How much will you need to invest at 2.5% to have earned $900 in interest in 5 years

Evgen [1.6K]

Answer:

we need $7200 to earn $900 in 5 years.

Step-by-step explanation:

Simple Interest formula: $\frac{PRT}{100}$ .......where p is principal, r is rate of interest, t is time

Using the formula:

$\frac{p*2.5*5}{100} =900$

${p*2.5*5} =900*100$

$12.5p =90000$

$p = 90000/12.5$

$p=7200$
