KengaRu [80]

Answer:

$\$833.97$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=10\ years\\ P=\$650\\ r=2.5\%=2.5/100=0.025\\n=4$

substitute in the formula above

$A=650(1+\frac{0.025}{4})^{4*10}$

$A=650(1.00625)^{40}$

$A=\$833.97$

34kurt

Answer:

I believe it's 22/15

Step-by-step explanation:

17x -6 + 3x - 5 = 1x + 11 + 4x first you add the 17x and 3x and 1x and the 4x

which it would be: 20x - 6 -5 = 5x + 11;

20x - 11 = 5x + 11,

-5 -5

15x - 11 = 11

+11 +11

15x = 22

15 15 Divide

x = 22/15

This means for every 1 can of black paint there are 2 cans of white paint in the mix

Step-by-step explanation:

The constant of proportionality is the gradient of line which can be evaluated as follows;

Gradient = delta y / delta x

Gradient = (y2 – y 1) / (x2 – x1)

We shall pick two points on the line graph in (x,y) format;

(3. 6) and (1, 2)

We evaluate the gradient now be repalivn the points on the formula;

Gradient = (2 – 6) / 1 – 3

Gradient = - 4 / - 2

Gradeint = 2/1 = 2

= 2

This means for every 1 can of black paint there are 2 cans of white paint in the mix
