Answer:

$ 2155.62

Step-by-step explanation:

regular pay rate = 11.10

overtime pay rate = 1.8 * 11.10

142 *  $11.10        +         29 * ( 1.8 * $ 11.10)        =   $  2155.62

Answer:

Movie: 1:35pm

Soccer Game: 1:05pm

Concert: 1:50pm

Step-by-step explanation:

Movie:

Starting at 11:20am and ends in 2 hours and 15 minutes

hours : minutes

2 hours after 11am is 1pm

15 minutes after 20 is 35

so the movie will end at 1:35pm

Soccer Game:

Starting at 11:35am and ends in 1 hour and 30 minutes

hours : minutes

1 hour after 11am is 12pm

30 minutes after 35 is (65) 5 minute of the next hour (1 hour and 5 mins total)

so the soccer game will end at 1:05pm

Concert:

Starting at 12:15pm and ends in 1 hour and 35 minutes

hours : minutes

1 hour after 12pm is 1pm

35 minutes after 15 is 50

so the concert will end at 1:50pm

Answer:

1:35pm

Soccer Game: 1:05pm

Step-by-step explanation:

Answer: five times two times four plus three plus four

Step-by-step explanation:

5[2(4) + 3 +4]

whenever you have a number next to a bracket, like [ or ( ,it always means multiply. So thats how i know 5[2(4) means "five times two times four" as a verbal expression. The last part is "3+4" which translates to "three plus four"

I hope this is correct!!!

Answer:

-2

Step-by-step explanation:

if you divide 8 by -2 you get -4

Answer:

The solution of a number divides by 8 equals to 4.

Step-by-step explanation:

This statement does not match the condition discussed above.

Answer: A

Step-by-step explanation:

Let's fact check all the answer choices:

A. He used the commutative property

Well, the commutative property states that you can put the equation in any order and the result doesn't change. In step1, andrew makes the equation  -5.7+2.2 into 2.2-5.7. Both of these equations equal -3.5, so yes, he used the commutative property.

B.He used the distributive  property.

We know this is wrong because the distributive property involves multiplication. An Example of an equation that involves the distributive  property is 3(2+1), or 3x(2+1).

C. He used the associative property.

This is wrong because the associative  property involves grouping the equation into different parentheses , which doesn't happen.

D.  The answer is incorrect

Using a calculator , we know this is wrong.

Hope this helps :)) Also if i could have brainliest id really appreciate it :D

Answer:

4.6

Step-by-step explanation:

Answer:

1. 96%

2. $6000

3. 176

4. 20%

Step-by-step explanation:

1. 1/5 of 80% is 16%. 80+16=96

2. 25% of 8000 is 2000. 8000-2000= 6000.

3. 10% increase of 200 is 20. 20+200=220. 20 percent of 220 is 44. 220-44=176

4. if you increase the original salary by 20%, then decreasing it by 20% of the new salary will give you the old salary.

Answer:

B)2

Step-by-step explanation:

We want to figure out the 415th digit of this repeating decimal.

[tex] \dfrac{2}{7} = 0. \overline{285714}[/tex]

Obviously it's almost impossible and absurd to find the answer by writing down all the 415 digits. So instead we're going to use some tricks to do so.

There're 6 repeating digits. dividing 415 by 6 yields 69.17. Now multiplying 69 by 6 yields 414 which means that the 414th digit of the repeating decimal would be the last digit of the repeating digits, that is,4 and hence The 415th digit of the repeating decimal is gonna be 2. Hence the answer is B

Answer:

There are 60 different outcomes.

Step-by-step explanation:

For each of these possibilities, there are four remaining possibilities for second place-we then multiply five and four. For third place, we have three remaining possibilities for each of the preceding results--calculate the product of five, four, and three, which is 60.

4*3*5=60

Answer:

  500 cm³

Step-by-step explanation:

Using the given values in the given formula, we find the volume to be ...

  [tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}(3)(5\text{ cm})^3 = 4(125\text{ cm}^3) = \boxed{500\text{ cm}^3}[/tex]

The volume of the sphere is about 500 cubic centimeters.

_____

Additional comment

The actual value of pi would add about 4.72% to this figure, bringing the estimate to about 523.6 cm³.

Step-by-step explanation:      

Step 1: Formula

Solve for: Volume

Formula: V=4/3 πr^3

Explanation in words (Short Form)

-  The first step is to use the formula and simplify it. So first we will use the formula which is V = 4/3 π and then divide it by 3, 3 times.

- The second step is to solve and at the end the answer will result as 523.59. Here is the full explanation and how I solved it.

V = 4/3 π r³ = 4/3 × π × 5³ = 523.59878

Answer:  

V≈523.6

Full Answer: 523.59878 OR 500

Answer: G.

Step-by-step explanation:

The formula for a circle's circumference is C = 2[tex]\pi r[/tex]

r = radius

We know the rectangle ABCD has a perimeter of 72 cm.

The rectangle is divided into 6 perimeter sides: AP, PB, BC, CQ, QD, and DA.

If we divide 6 sides to the rectangle's perimeter, we can calculate the length of one side.

72 / 6 cm = 12 cm

A side of the perimeter of the rectangle ABCD is equal to 12 cm, which means PQ, the radius of the circle is equal to 12 cm.

C = 2[tex]\pi r[/tex]

radius = 12 cm

C = 2[tex]\pi[/tex] * 12 cm

C = 2 * 12 * Pi cm

C = 24[tex]\pi[/tex]

Answer = G.

Hope I Helped!

Answer:

24pi (G)

Step-by-step explanation:

This question might seem hard at first, but we know one crucial piece of information- line PQ- is the circle's radius. We also know that Q "fits perfectly" on line DC, and that angle QPB is a right angle. Since the line is straight and passes through THE MIDDLe of the rectangle, we can assume that line PQ divides the rectangle into two squares. Since squares have 4 corresponding sides, or sides with the same length, we can rewrite the equation as x+x+2x+2x, which is 6x = 72. Apply and find your answer.

EASIER EXPLANATION:

the radius is at a right angle, meaning it divides the rectangle into two squares.

It is stated that the perimeter of the rectangle is 72, meaning if we write it into an equation where x = short sides and y = long sides.

x+x+y+y = 72

However, the long sides really equal 2x, so we can rewrite the equation

x+x+2x+2x = 72

Simplify

X+x+x+x+x+x = 72

Simplify more

6x = 72

solve

x = 12

We also know that 2x is the dimeter, which is 24.

Apply to the circumference equation

C= Dpi

Since all our answeres are in pi form, we don't need to solve

ANSWER= 24

Split the integrand into partial fractions.

[tex]\dfrac{9x+2}{x^2+x-6} = \dfrac{9x+2}{(x-2)(x+3)} = \dfrac a{x-2} + \dfrac b{x+3}[/tex]

[tex]\implies 9x+2 = a(x+3) + b(x-2) = (a+b)x + (3a-2b)[/tex]

[tex]\implies \begin{cases}a+b=9 \\ 3a-2b=2\end{cases} \implies a=4,b=5[/tex]

Then we have

[tex]\displaystyle \int \frac{9x+2}{x^2+x-6} \, dx = 4 \int \frac{dx}{x-2} + 5 \int \frac{dx}{x+3} \\\\ = \boxed{4\ln|x-2| + 5\ln|x+3| + C}[/tex]

which follows from the result

[tex]\displaystyle \int \frac{dx}x = \ln|x|+C[/tex]

Answer: I would say A or C bc they are similar but C seems more reasonable.

Step-by-step explanation:

Answer:

c = 14.6

Step-by-step explanation:

[tex]\textrm {Applying the Pythagorean Theorem : }[/tex]

⇒ a² + b² = c²

[tex]\textrm {Here, we are given :}[/tex]

⇒ a = 4

⇒ b = 14

[tex]\textrm {Solving :}[/tex]

⇒ c² = 4² + 14²

⇒ c² = 16 + 196

⇒ c² = 212

⇒ c = √212

⇒ c = 14.6 [tex]\textrm {(nearest tenth)}[/tex]

Answer:

Step-by-step explanation:

Answer:  No

Explanation:

Replace p with 2 and simplify

8 ≠ 3p + 2

8 ≠ 3(2) + 2

8 ≠ 6 + 2

8 ≠ 8

We get a false claim, so the original inequality 8 ≠ 3p + 2 is false when p = 2. Meaning that p = 2 is not a solution.

If the "not equal" sign was changed to an equal sign, then we would have a solution.

Answer:

no / false

Step-by-step explanation:

If we set the "p" in this equation to be equal to 2 (p = 2), we can test this inequality:

8 ≠ 3p + 2

8 ≠ 3(2) + 2

8 ≠ 6 + 2

8 ≠ 8

FALSE STATEMENT

so, p = 2 is not a solution to this inequality

(no)
