Answer:

A) The value of a is <u>29</u>.

B) The value of b is <u>greater than 29</u>.

C) In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

D) The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

Step-by-step explanation:

Solving for Part A.

Given,

a-9=20

We have to solve for a.

a-9=20

By using addition property of equality, we will add both side by 9;

a-9+9=20+9\\a=29

Hence the value of a is <u>29</u>.

Solving for Part B.

Given,

b-9>20

We have to solve for b.

b-9>20

By using addition property of inequality, we will add both side by 9;

b-9+9>20+9\\b>29

Hence the value of b is <u>greater than 29</u>.

Solving for Part C.

In both part A and part B we have used a common property  which is addition property and that we have add 9 on both side of equation in both parts.

Solving for Part D.

The value of a in part A is equal to 29 whereas in part B the value of b is greater than 29.

The < is just like and equal sign just looks a little different think of it that was for the first couple steps. So you have 13-3y<-5. First do, -5+13=8. Now you have -3y<8. Then your want to do 8 divided by -3 and you get=-2.666666667 and that equals y.

-2.7=y then make that equal sign into the normal sign again. -2.7

Which is the approximate measure of this angle A. 30 b. 90 c 120 d 180
statuscvo [17]

Answer:

Answer is A. 30 degree

as we know that two prependicular lines have 90 degree angle between them

and similarly a horizontal line has angle zero degree.

the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines

but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.

Find the compound interest on ₹ 31,250 at 12% pa for 2 1/2 years
IRISSAK [1]

Answer:

42,183

Step-by-step explanation:

We will use the Continuous Compounding Interest since a regular interval was not stated.

P(t) = Pe^(rt)

We will plug in the variables to the formula

P(t) = 31250 * e^(.12 * 2.5)

We can simplify and evaluate the compound interest.

P(t) = 42183.08
