Estimate the quotient using compatible numbers. 63.52 Divided by 7.9

Answers

Answer 1

Answer: Alright, to get this answer, what we need to do first is round. Because 63.52 is close to 64, and 7.9 is close to 8, we can change this problem from 63.52 divided by 7.9 to 64 divided by 8, which is a far easier question to do without a calculator. When we do 64 divided by 8, we get 8, which should be pretty close to the answer of 63.52 divided by 7.9.

Answer 2

Answer: rounding 63.52 to whole numbers=64
rounding 7.9 to whole number=8
64 ÷8=8

Answer:

Hello my friend! The first step is to isolate the x and the 40 like this: x2 = 40.

Step-by-step explanation:

After you do that, you can perform the inverse operation of the x2, wich is the sqrt of 40. This way, you will have x=sqrt40 . X~=6.32

Which ordered pairs are in the solution set of the system is liner inequalities y>-1/3x+2 y<2x+3

Answers

Answer:

Option (1)

Step-by-step explanation:

Given linear inequalities in the graph are,

$y\geq -(1)/(3)x+2$

y < 2x + 3

Here shaded area above the solid line represents the inequality,

$y\geq -(1)/(3)x+2$

And shaded area on the right side of the dotted line represents the solution set of the inequality,

y < 2x + 3

And the solution set of the system of linear inequalities will be represented by the common area of these inequalities.

Therefore, ordered pairs (2, 2), (3, 1) and (4, 2) will lie in the common shaded area.

Option (1) will be the answer.

What is the measure of AC?
Enter your answer in the box. Enter only the numerical value.

Answers

Step-by-step explanation:

Angle BDC is an angle inscribed in a circle. As such it intercepts TWICE as many degrees of arc as its measure

so: 2 * (3x-1.5) = 3x+9

6x -3 = 3x+9

x = 4

then the arc AC = 3x+9 = 21 degrees

Jose has $178.74 in his checking account. He wrote checks for $36.52, $18.92, and $25.93. He also deposited $300.00, $100.00, and $205.16. What is the final balance in Bob's checking account?V

Answers

Answer:

$702.53

Step-by-step explanation:

Start with Jose's initial balance.

$178.74$

He wrote checks, so we have to subtract the total amount the checks were worth. Let's first add the three amounts.

$36.52+18.92+25.93$

Solve.

$81.37$

Subtract the total amount of the checks from Jose's initial balance.

$178.74-81.37$

Solve.

$97.37$

The amount above is now what is in Jose's checking account.

But, he also deposited money, meaning he put money in his checking account. Now, let's add the three amounts he deposited.

$300.00+100.00+205.16$

Solve.

$605.16$

The amount above is what Jose adds to his checking out.

Add the total value of the deposited money and his new balance.

$605.16+97.37$

Solve.

$605.16+97.37=702.53$
