D: (x,y) → (x +1, y - 8)

Step-by-step explanation:

The red shape, KHIJ, is similar to the blue shape, KHIJ.

Looking at the shapes from the points K, Blue K is forward on the x-axis by 1, Hence x + 1.

Lokkin at the same points, but on y-axis this time. Red K is up 2 and Blue K is down 6. 2 + 6 = 8. Since the blue shape is down, make the 8 into -8. Now you have y -8.

A total of $8000 is invested: part at 6% and the remainder at 10 %. How much is invested at each rate if the annual interest is $750?​

Answers

Answer: $400 was invested

Step-by-step explanation: Based on the scenario in the question, our calculation goes thus:0.11x + 0.06(8000 - x) = 5000.11x + 480 - 0.06x = 5000.11x - 0.06x = 500 - 4800.05x = 20x = 20/0.05x = 400

$400 was invested at 11% Also, 8000 - 400 = 7600 invested at 6%

If the measure of angle 1 is (3 x minus 4) degrees and the measure of angle 2 is (4 x + 10) degrees, what is the measure of angle 2 in degrees?

Answers

Answer:

its 58

Step-by-step explanation:

The measure of angle 2 is 58 degrees

How to determine the measure of angle 2?

The figure that completes the question is added as an attachment

The given parameters are:

Angle 1 = 3x - 4Angle 2 = 4x + 10

Both angles add up to 90 degrees.

So, we have:

3x - 4 + 4x + 10 = 90

Evaluate the like terms

7x = 84

Divide both sides by 7

x =12

Substitute x =12 in Angle 2 = 4x + 10

Angle 2 = 4 * 12 + 10

Evaluate the expression

Angle 2 = 58

Hence, the measure of angle 2 is 58 degrees

According to these three facts, which statements are true?

Circle W has center (−3, 0) and radius 8.
Circle V is a translation of circle W, 2 units down.
Circle V is a dilation of circle W with a scale factor of 2.


Select each correct answer.

The radius of circle V is 16.

The center of circle V is (−5, 0).

Circle V and circle W have the same center.

Circle V and circle W are similar.

Answers

a.

Circle W centre is (-3,0) - (0,-2)* = (-3,-2)

*note that the centre of the circle W is going down by 2 units this only affects the y axis hence the substraction

A dilation of a factor of 2 does not change the centre of the circle rather the radius ( the size of the circle decreases and hence the radius)

So now the radius becomes 8 UNITS/2 = 4UNITS

Mira buys a telescope that costs $180. She has to pay 4% sales tax. how much will she pay in all

Answers

$187.2 Explanation: the total before take is $180 which is 100% tax is 4%. The total plus 4% sales tax is 104% of the original $180. If you shift the numbers two places(as you do when converting % to decimals) you get 1.04. 180 x 1.04 = 187.2

Mira would pay $187.2

What is the formula for tax rate?

"Tax rate = (Tax amount / Price before tax) × 100% "

What is the formula for tax amount?

"Tax amount = Final price - Price before tax"

For given question,

Mira buys a telescope that costs $180.

⇒ Price before tax = $180

sales tax = 4%

Let 'm' be the tax amount.

Using the formula of tax rate,

⇒ Tax rate = (Tax amount ÷ Price before tax) × 100%

⇒ 4% = ([tex]\frac{m}{180}[/tex]) × 100%

⇒ 0.04 × 180 = m

⇒ m = 7.2

Using the formula for the tax amount,

⇒ Tax amount = Final price - Price before tax

⇒  Final price = Tax amount + Price before tax

⇒  Final price = 7.2 + 180

⇒  Final price = $187.2

Therefore, Mira would pay $187.2

The population of a village has increased this year by 8 percent.This year it's population is 10,800.How much was it's population last year?​

Answers

Answer:

SOLUTION:-

Let,last year population be x.We have last year population+Increased population=10,800

[tex]x + 8\% \: of \: x = 10800[/tex]

[tex]\displaystyle{x + \frac{8x}{100} = 10800 }[/tex]

[tex]\displaystyle{ \frac{100x + 8x}{100} = 10800}[/tex]

[tex]\displaystyle{ \frac{108x}{100} = 10800}[/tex]

[tex]108x = 10800 \times 100[/tex]

[tex]108x = 1080000[/tex]

[tex]x = \displaystyle{ \frac{1080000}{108} }[/tex]

[tex]x = 10000[/tex]

Therefore,required last year population=10000

Answer:

The Correct Answer is 10,000.

Step-by-step explanation:

Becuase The Question itself is providing us that this year it increased by 8%. Then the said that the total population for this year is 10,800. So, that tells us that the 8% equal 800. 10,000+800=10,800.

10,800-800=10,000

The correct answer is 10,000.

invests $6,688 in a savings
account with a fixed annual interest rate of
2% compounded 6 times per year. What
will the account balance be after 5 years?

Answers

Answer:

$7,390.15

Step-by-step explanation:

A = $7,390.15

A = P + I where

P (principal) = $6,688.00

I (interest) = $702.15

First, convert R as a percent to r as a decimal

r = R/100

r = 2/100

r = 0.02 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 6,688.00(1 + 0.02/6)^(6)(5)

A = 6,688.00(1 + 0.0033333333333333)^(30)

A = $7,390.15

Summary:

The total amount accrued, principal plus interest, with compound interest on a principal of $6,688.00 at a rate of 2% per year compounded 6 times per year over 5 years is $7,390.15.
