If 30% of a number is 15, what is 25% of the number?

Answers

Answer:

12.5

Step-by-step explanation:

Basically, the number was multiplied by .3 to get 15. So if you do 15/.3 you'll get your original number which is 50. Then you multiply by .25 and get 12.5.

Write the equation of a line with a slope of -7/2 passing through the point 2,-4

Answers

Answer:

y = -7/2x+3

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

y = -7/2 x+b

Substitute the point into the equation

-4 = -7/2(2) +b

-4 = -7+b

Solving for b

-4+7 = -7+b+7

3 = b

The equation is y = -7/2x+3

0
B. $30,170.36
C. $17.250.00
ОО
D. $26,250.45

Answers

Answer:

p=$15000

R=15%

t=5years

compound amount CI=?

Step-by-step explanation:

we have

CI=p(1+R/100)^t=$15000(1+15/100)^5=$15000×1/15^5=$30170.35

The total amount of $15,000 at 15% compounded annually for 5 years will be $30,170.36 so option (B) is correct.

What is compound interest?

Compound interest is applicable when there will be a change in principle amount after the given time period.

The rate at which compound interest accrues depends on the frequency of compounding.

For instance, if you offer someone $500 at a rate of 10% annually, $500 will be considered your principal sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.

Given

Principle amount = $15000

Rate of interest = 15%

The time period T = 5 years.

Compound interest formula

A = P  [tex][ 1 + R/100 ]^{T}[/tex]

A = 15000 [tex][ 1 + 15/100 ]^{5}[/tex]

A = $30,170.36 hence, the total amount after 5 year will be $30,170.36.

Answers

Answer:

The true statements are;

A. The point (0, -3) is on the line

C. The point (-6, -6) is a point on the line

Step-by-step explanation:

The question relates to the finding of the equation of a straight line graph

The x-intercept of the graph is (6, 0) and the graph passes through the point (2, -2)

Therefore, the slope of the graph is m = (-2 - 0)/(2 - 6) = 0.5

The equation of the graph in point and slope form is given as follows;

y - 0 = 0.5 × (x - 6)

∴ y = 0.5·x - 3

Therefore, the equation of the graph in slope and intercept form, y = m·x + c is also y = 0.5·x - 3

A. The y-intercept of the graph is (0, -3), therefore, the point (0, -3) is on the line

B. The equation of the graph, y = 0.5·x - 3, can be written as follows;

8·y = 8 ×0.5·x - 8 × 3 = 4·x - 24

∴ 8·y - 4·x = -24

C. When y = -6, 'x' is given as follows;

 y = 0.5·x - 3

-6 = 0.5·x - 3

0.5·x = -6 + 3 = -3

x = -3/0.5 = -6

x = -6

Therefore, when y = -6, x = -6, and (-6, -6) is a point on the line

D. When x = 0, 'y', is given as follows;

y = 0.5·x - 3

When x = 0, y = 0.5 × (0) - 3 = -3

Therefore the point (0, -3) is on the line and the point (0, -4) is not on the line

E. The point (-6, 0) represent an x-intercept of a line graph, however the x-intercept on the given line is (6, 0) and when y = 0 on the line, x = 6

Therefore, the point (-6, 0) is not on the line

F. The equation of the graph is 8·y - 4·x = -24, therefore, - 4·x + 8·y = 24 does not represent the equation of the graph
