half of the flowerbed?

Answers

Answer:

Wait what

Step-by-step explanation:

Answer:

2 bags

Step-by-step explanation:

Circumference is:

C = πr

Then the radius:

r = C/π = 8.5/3.14 = 2.7 ft

The area:

A = πr² = 3.14*2.7²= 22.89 ft²

Half of the area:

22.89/2 = 11.445 ft² ≈ 12 ft² rounded up

Sasha paid $68 for a painting frame during a 20% sale event. Find the original price of the frame.

Answers

Answer:

$68.20

Step-by-step explanation:

Answer:

85$

Step-by-step explanation:

p = original price

68 = p - 20%p

68 = p - 0.20p

68 = 0.80p

85 = p

The original price was $85.

The original price is 100%. The sales price was 20% off - subtract. So the sale price was 100% - 20% = 80%.

Incase you wanna know how I came up with the 0.80p :)

Identify the vertex of the quadratic function

Answers

Answer:

(-2,-1)

Step-by-step explanation:

On the graph, the vertex is where the bottom of the U is. In general, it's always that same place on the U, but the U could be turned upside down or left or right. Looking at the bottom of the U, count on the x axis first (left 2, which is negative). That's your first number. Then count on the y axis (down 1, again, negative). That's your second number.

Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it. At the end of the 4 years, how much interest in dollars and cents did the account earn? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.

I tried, but I'm not a math whiz or anything.

The amount of interest is $1170.

What is the compound interest?

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].

Given that, principal =$6500, rate of interest =4.25% and time period = 4 years.

Here, Amount = 6500(1+4.25/100)⁴

= 6500(1+0.0425)⁴

= 6500(1.0425)⁴

= 6500×1.18

= $7670

Interest = Amount-Principal

= 7670-6500

= $1170

Therefore, the amount of interest is $1170.

can someone help me find the equation for this line please

Answers

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1

3y- 3x + 3 =15 solve for y.

Answer:

mode: none

median: 4

mean: 4.2

Step-by-step explanation:

when dealing with mean, median, mode the first thing you should do is arrange the numbers in order from least to greatest. Once you have done so the easiest thing to do first is see which number is in the very middle, this is your median. Mode is the number that appears the most. Mean is another word for average. To find the mean, add up all the numbers then divide the sum of all the numbers by how many numbers are listed. In this case, 2+3+4+5+7=21.

21 divided by 5 (how many numbers there are) = 4.2

What is the system of equations?

A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.

Let's use the given information to set up a system of equations to solve for Ryan's age.

We know that Ryan's age, y, is twice Chaise's age, x, so we can write:

y = 2x (Equation 1)

We also know that Ryan is 11 years older than Chaise, so we can write:

y = x + 11 (Equation 2)

Now we can substitute Equation 1 into Equation 2:

2x = x + 11

Simplifying, we get:

x = 11

So Chaise is 11 years old.

To find Ryan's age, we can use either Equation 1 or Equation 2. Let's use Equation 2:

y = x + 11

y = 11 + 11

y = 22

Therefore, Ryan is 22 years old.

If the circumference of a circle is 82p , then the value of ‘r’ is

(i) 41 cm
(ii) 82 cm
(iii) 21 cm
(iv) 20 cm​

Answers

Answer:

41cm

Step-by-step explanation:

The circumference of a circle is 82π

Therefore r can be calculated as follows

2 × π × r= 82× π

2πr= 82π

r = 82π/2π

r= 41

Hence r is 41cm

Audrey makes a certain shade of blue paint. She uses 3 1/2 quarts of blue paint with 5 quarts of white paint. Her cousin Evan will do the same. He will mix w quarts of white paint with b quarts of blue paint. Which of these equations represents the relationship between w and b ?

5 quarts of white

3 1/2 α 5

7/2 = 5k

Where k is the proportionality constant

k = 7/2 ÷ 5
