Answer 1

Answer:

Third option : 9^10 / 9^2

Step-by-step explanation:

9^2 . 9^6

Formula / Identity : -

a^m . a^n = a^( m + n )

Here,

a = 9

m = 2

n = 6

9^2 . 9^6

= 9^( 2 + 6 )

=9^8

9^10 / 9^2

Formula / Identity : -

a^m / a^n = a^( m - n )

Here,

a = 9

m = 10

n = 2

9^10 / 9^2

= 9^( 10 - 2 )

= 9^8

Therefore,

9^10 / 9^2 is equivalent to 9^2 . 9^6.

Answer 2
C because you need to subtract the powers in order to get the answer because when you have the same number but different power the power will stay the same the only thing that changes is the power your either adding or subtracting in this case your subtracting nine to the tenth power by 2 which is nine to the eighth power

A mortgage loan is termed as a loan that is used to purchase or maintain a home, land or other pieces of real estate.

The borrower agrees to repay the amount of loan to the lender over a period of time, usually in a series of regular installments divided into principal and interest. The property is used as security for the loan.

Calculation of the amount of mortgage is as follows:

[tex]\text{Interest}= \text{Mortgage amount} \times\frac{0.05}{12}\times3[/tex] = 1875

[tex]\text{Principal Pay }= 1000 \times3[/tex] = 3000

Total amount paid = Interest + principal pay = 1875 + 3000 = 4875

Initial balance = 150000

The remaining balance for the mortgage amount = initial balance - the total amount paid.

Amount of mortgage = $ 145125.

Therefore the closest to the mortgage balance after 3 months of payments is

(1) $145,165.

Answer: 55 Square inches

Step-by-step explanation:

You should find the area of the square and rectangle separately

To find the area you multiply length times width, so the area of the square is 4×4 which equals 16

Then you do the same to the rectangle, 13×3=39

To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55

55 square inches!!! I hope that the right answer ? But yea uh good luck lol

Hi if you answer please explain how you got the answer thanks! :) ​

Answers

Answer:

B: 60,000

Step-by-step explanation:

Since there was a total of 200,000 votes, we can create this equation, since we also know the ratio between the two candidates:

7x + 3x = 200,000

x can be seen as a common factor between the two candidates that can be used to express their difference

We can now further simplify this equation by combining like terms and solving for x:

10x = 200,000

x = 200,000/10

x = 20,000

Now, to find the total number of votes cast for Bob Tanks, we multiply x by 3, since it says that Julie Sanders won by a ratio of 7:3, which means she had 7 in the ratio and Bob had the 3.

3x = 3(20,000) = 60,000

The answer is B: 60,000.

Answer: 60,000

Step-by-step explanation:

The easiest way to solve this problem is to use equations

Since we know the ratio of Julie's votes to Bob's votes is 7:3 and the total is 200,000 we can use this equation 200,000 (number of votes)  = 7x(Julie's votes) + 3x(Bob's votes)

After you solve it you get x=20,000

Then,

You put that back into Bob's votes and you get 60,00

You bought an item for $25 on Ebay and plan on marking it up 65%. What price will you sell your item for to the nearest dollar?

Answers

Answer:

$41.25

Step-by-step explanation:

The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.

Let's make an equation.

65/100 • 25 = x

Multiply.

x = 16.25

Now we know how much you want to mark it up by.

Add this to your base of $25.

25 + 16.25

= 41.25

You want to sell it for $41.25.

Hope this helps!

Segment MN and Segment PQ intersect at R, as seen in the diagram at the right. Find x, m∠ MRQ, m∠ QRN, m∠ NRP, m∠ PRM.

A) x=10, m
B) x=20, m
C) x=15, m
D) x=18, m

Answers

Answer is 18

18 • 7 = 126
126 - 11 = 115
4 • 18 = 72
72 - 7 = 65

115 + 65 = 180

They are supplementary angles, which mean they together equal 180°

The value of x which is included in terms of both the angles ∠PRM and ∠NRP is given by: Option  D: x = 18

What are supplementary angles?

Two angels whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

Here, we're specified that:

m∠PRM = measure of angle PRM = (7x -11)°m∠NRP = measure of angle NRP= (4x -7)°

They are adjacent and line segments MR and RN are forming a straight line MN, so these angles are supplementary. That means:

(7x -11)° +  (4x -7)° = 180°

Opening the brackets, and solving in terms of magnitude, we get:

[tex]7x - 11 + 4x -7 = 180\\11x - 18 = 180\\11x = 180+18 \\\\x = \dfrac{198}{11} = 18[/tex]

Thus, the value of x which is included in terms of both the angles ∠PRM and ∠NRP is given by: Option  D: x = 18

Patio is in the shape of a parallelogram.

Formula for the area of a parallelogram is,

Area = [tex](\text{Base})(\text{Height})[/tex]

        = 16.2 × 12

        = 194.4 square feet

∵ 50 square feet area is covered by 1 bag of concrete mix.

∴ 1 square feet area will be covered by [tex]\frac{1}{50}[/tex] bag of concrete mix

∴ 194.4 square feet patio will require the concrete mix = [tex]\frac{194.4}{50}[/tex]

                                                                                           = 3.888

                                                                                           ≈ 4 bags

Therefore, 4 bags of concrete mix will be required by Dave to add a new patio.

Answers

Répondre:

AI = 32,36 m

IE = 30,78 m

Explication étape par étape:

Utilisation de Pythagore:

Cosθ = adjacent / hypoténus

AI = hypoténus

θ = 72 °

Adjacent = 10 m

Cos 72 = 10 / AI

0,3090169 = 10 / AI

AI = 10 / 0,3090169

AI = 32,36 m

De la trigonométrie;

IE = opposé

Adjacent = 10m

Tanθ = opposé / adjacent

Tan 72 = IE / 10

IE = Tan 72 * 10

IE = 3,0776835 * 10

IE = 30,78 m

You bought 7 raffle tickets. A total of 1302 raffle tickets were sold. If every raffle ticket has an equal chance at winning, what is your probability of not winning?

Answers

Answer:

the probability of not winning is 0.9946

Step-by-step explanation:

The computation of the probability of not winning is shown below:

The Probability of winning is

= 7 ÷ 1302

So, the probability of not winning is

= 1 - 7 ÷ 1302

= (1302 - 7) ÷ 1302

= 1295 ÷ 1302

= 165 ÷ 186

= 0.9946

Hence, the probability of not winning is 0.9946

N artist makes three types of ceramic statues (large, medium, and small) at a monthly cost of $760 for 210 statues. The manufacturing costs for the three types are $5, $4, and $3. If the statues sell for $26, $18, and $15, respectively, how many of each type should be made to produce $3,640 in monthly revenue?

Answers

Answer:

20, 90 and 100

Step-by-step explanation:

Total number of statues = 210

Assuming that a large statue = x, medium statue = y and a small statue = z

Then, x + y + z = 210........i

Also, we're told that the monthly cost is $760, so

5x + 4y + 3z = 760.........ii

Cost of selling is $3640, so then

26x + 18y + 15z = 3640.........iii

Solving i and ii simultaneously, we have

5x + 5y + 5z = 1050

5x + 4y + 3z = 760

Subtracting, we have

y + 2z = 290.........iv

Again, solving ii and iii simultaneously, we have

130x + 104y + 78z = 19760

130x + 90y + 75z = 18200

On subtracting, we have

14y + 3z = 1560.........v

And finally, solving iv and v simultaneously, we also have

14y + 28z = 4060

14y + 3z = 1560

On subtracting,

25z = 2500

z = 2500 / 25

z = 100

Substituting for z = 100 in iv, we have

y + 2(100) = 290

y + 200 = 290

y = 290 - 200

y = 90

Substituting for y = 90, and z = 100 in i

x + 90 + 100 = 210

x + 190 = 210

x = 210 - 190

x = 20

Therefore, large statues has to be 20, medium statues has to be 90, and small statues has to be 100

How much will Rosa pay after the discounts and 6% tax have been applied? Write and solve an equation to find the final price.

Answers

Answer:

$405,44

Step-by-step explanation:

Equation: 499.99 - (499.99 x 15/100) - 1/10[499.99-(499.99 x 15/100)] + 6/100{1/10[499.99-(499.99 x 15/100) = x

Steps: x = (15 x 499.99)/100 = $74.9985

499.99 - 74.9985 = $424,9915

x = (424,9915 x 10)/100 = $42,49915

424,9915 - 42,49915 = $382,49235

x = $22,949541

382,49235 + 22,949541 = $405,441891

That can be rewritten as $405,44.
