А. 6.3 cm
В. 3.1 cm
с. 5.2 cm
D. 7.9 cm​

Answer:

t = 10n + 25

Step-by-step explanation:

At the end of n weeks, the total amount that Melissa would have can be found by the function, t = 25 + 10n.

Melissa made $25 from washing her mother's car and keeps it aside.

She then makes $10 every week. This means that in n number of weeks, the amount she would have made from chores is:

= Amount per week x number of weeks

= 10 x n

= 10n

The total she would then have in n weeks is:

= Amount saved from mother + Amount earned from chores in n weeks

= 25 + 10n

This total is t, so the total function is t = 25 + 10n.

Answer:

Kayla will not have enough because the total will be $225.67

Step-by-step explanation:

2 * 9.98 = 19.96

3 * 24.99 = 74.97

19.96 + 25.99 = 45.95

45.95 + 74.97 = 120.92

120.92 + 89.99 = 210.91

0.07 * 210.91 = 14.76

210.91 + 14.76 = 225.67

Kayla will not have enough because the total will be $225.67

Since there is a budget of $200. The sales tax rate is 7%

Also, the following items should be purchased

2 T-shirts, $9.98 each

1 pair of pants, $25.99

3 dresses, $24.99 each

1 pair of shoes, $89.99

So, the calculations should be

2 of 9.98 = 19.96

3 of 24.99 = 74.97

Now the total should be

19.96 + 25.99 = 45.95

45.95 + 74.97 = 120.92

120.92 + 89.99 = 210.91

0.07 of 210.91 = 14.76

And, finally

210.91 + 14.76 = 225.67

Therefore, Kayla will not have enough because the total will be $225.67

Answer:

There were 25 pizzas made last week.

Step-by-step explanation:

It is given that 64% of the pizzas had extra cheese and 16 pizzas had extra cheese. So it means that 64% is equals to 16 pizzas. In order to find how many pizzas were made, you have to find the remaining percentage of pizzas without extra cheese by subtracting 64% from 100% :

100 - 64 = 36 % of pizzas without extra cheese

64 % = 16 pizzas

1 % = 1/4 pizza

36 % = 9 pizzas

We have found out that 9 pizzas were made without extra cheese. The total pizzas were made last week is 25 pizzas (including extra cheese and no extra cheese) :

Total = Extra Cheese + No extra cheese

= 16 + 9

= 25 pizzas

The measure of angle VU is 240°.

Given that arc SV has a measure of **120°** and angle STV is **82°**, we can find the measure of angle VU.

1. The central angle STV is equal to the measure of arc SV. Therefore, ∠STV = 120°.

2. The sum of angles around a point (360°) is equal to the sum of the central angle and the inscribed angle. So, ∠VU + ∠STV = 360°.

3. Solving for ∠VU:

  - ∠VU + 120° = 360°

  - ∠VU = 360° - 120°

  - ∠VU = 240°

Therefore, the measure of angle VU is 240°.

Answer:

8 ads

Step-by-step explanation:

To start off, we know we have a budget of $500 which means we cannot go above that amount. Ads cost $75 each but in our case they are now 20% cheaper. Lets figure out the new price of the ads. Remember to change 20% into its decimal form (20% -> 0.2)

75 x 0.2 = 15

Now we subtract 15 from 75 to get our new ad price.

75 - 15 = 60

Now to figure out how many ads we can get with a budget of $500, we simply divide 500 by 60. Don't forget to round the answer to the nearest whole number since we cannot go over our budget.

500 / 60 = 8 ads

Answer: 9ft² and 12.25ft²

Step-by-step explanation:

The range of the possible areas will be 9 square feet and 12.25 square feet. Then the correct option is B.

Coordinate geometry is the study of geometry using the points in space.

On a coordinate plane, the x-axis is labeled Side length and the y-axis is labeled Perimeter or area.

A line representing the perimeter goes through points (0, 0), (1, 4), (2, 8), (3, 12).

Then the equation of line will be

y = [(12 – 8) / (3 – 2)]x

y = 4x

A curved line representing the area goes through points (0, 0), (2, 4), (3, 9), and (4, 16).

y = x²

Andrew wants to build a square garden, and needs to determine how much area he has for planting.

The perimeter of the garden is between 12 and 14 feet.

Then the value of the side length corresponding to 12 and 14 will be

For y = 12, we have

12 = 4x

 x = 3

Then the area will be

y = 3²

y = 9 square feet

For y = 14, we have

14= 4x

 x = 3.5

Then the area will be

y = 3.5²

y = 12.25 square feet

Then the range of the possible areas will be 9 square feet and 12.25 square feet.

Then the correct option is B.

There is 1 orange marble out of 7 total. The probability of picking an orange marble is 1/7. Let A = 1/7 which we'll use later.

The probability of flipping tails is 1/2 because 1 side is tails out of 2 sides total. Let B = 1/2

Multiply A and B

A*B = (1/7)*(1/2) = (1*1)/(7*2) = 1/14

This represents the probability of getting an orange marble and flipping tails.

Arnold will have to pay $689546.98 after 30 years of taking out a loan.

The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.

The given problem is the case of compound interest.

The values for different parameters are as follows,

P = 195000

r = 4.3%

And t = 30 years

Now, substitute all the corresponding values in the expression for amount given below as,

A = P(1 + r/100)ⁿ

   = 195000(1 + 4.3/100)³⁰

   = 689546.98

Hence, the total amount to be paid after 30 years is given as $689546.98.

Answer: The radius is 11.5 meters (to the nearest tenth)

Step-by-step explanation: The circle with center H has an arc TX that measures 24 meters, and also the angle subtended by YX equals 120°.

The length of an arc is given b the formula;

Length of arc = (∅/360) x 2πr

Where the length of the arc is 24 and ∅ is 120, the formula becomes;

24 = (120/360) x 2(3.14) r

24 = (1/3) x 6.28 r

By cross multiplication we now have,

(24 x 3)/6.28 = r

72/6.28 = r

11.4649 = r

r ≈ 11.5

Therefore, the radius is approximately 11.5 meters
