A round garden has a circumference of 15.7 feet. Calculate the area of
the garden

Answers

Answer:

The area of a circle with circumference 15.7 is 19.62

Step-by-step explanation:

If this helped May I have brainliest Im trying to rank up.

Have a great day!

The area of the garden is 19.64 feet²

The garden has the shape of a circle.

The area of a circle = πr²

Where:

π= pi = 22/7

r = radius

In order to determine the area of the garden, the radius has to be determined first. The radius would be determined from the circumference of the circle.

Circumference of the circle = 2πr

15.7 = 2 x (22/7) x r

r = 15.7 ÷ ( 2 x 22/7)

r = 2.50 feet

Area of the garden = (22/7) x (2.5²) = 19.64 feet²

Answers

Answer:

112 calories per cup

Step-by-step explanation:

Let x = unit rate for calories per cup,

Then (3/4)*x = 84

and x = 84*(4/3) = 112 calories per cup

Answer:

1 cup =  128 calories

Step-by-step explanation:

you simply have to reverse the fraction and multiply it by that. 96×[tex]\frac{4}{3}[/tex]=128

Mary, John, and Stacy were paid $360 for working around , the house in a ratio of 3:6:9. How much more did Stacy make than John?

Answers

Answer:

$60

Step-by-step explanation:

Let the work done by Mary, John and Stacy be 3x,6x and 9x.

ATQ,

3x+6x+9x=360

18x = 360

x = 20

Mary's amount = 3x = 3(20) = $60

John's amount = 6x = 6(20) = $120

Stacy amount = 9x = 9(20) = $180

Difference in amont of Stacy and John = $180-$120 = $60

Hence, Stacy make $60 more than John's amount.

#3.) What is the domain and range the C to D part of the roller coaster?

Answers

Let's see what to do buddy....

_________________________________

1) Go...

We have the following equation for finding the slope of the line by using two points :

[tex]slope = m = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Where a and b are the points which the line through them.

We have points C and D here ,

So :

[tex]slope = m = \frac{y(d) - y(c)}{x(d) - x(c)} \\ [/tex]

D = ( 7 , 12 ) and C = ( 0 , 0 )

Now just need to put the coordinates in the above equation :

[tex]slope = m = \frac{12 - 0}{7 - 0} = \frac{12}{7} \\ [/tex]

_________________________________

2) Go...

We have the following equation to find the point-slope form of the linear functions :

[tex]y - y(o) =(slope) \times ( \: x - x(o) \: ) \\ [/tex]

Where o is one of the given points.

So we must choose one of the points ,

I choose : D = ( 7 , 12 )

Then we have :

[tex]y - 12 = \frac{12}{7}(x - 7) \\ [/tex]

It's point-slope form, so we need to simplifies it to find slope-intercept form.

Look:

[tex]y - 12 = \frac{12}{7}x - 12 \\ [/tex]

Both sides plus 12

[tex]y = \frac{12}{7}x \\ [/tex]

Now we have the slope-intercept form of the CD line.

3) Go...

Domain = [ 0 , 7 ]

Range = [ 0 , 12 ]

In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept:
Sale No Sale Row Total
Aggressive 255 325 580
Passive 472 108 580
Column Total 727 433 1160
Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa-passive approach, S-sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on.
A) Compute P(S), P(S | A), and P(S | Pa).
B) Are the events S-sale and Pa-passive approach independent? Explain.
A. Yes. P(S) P(S | Pa).
B. Yes. The two events can occur together.
C. No. The two events cannot occur together.
D. No. P(S)-P(s i Pa).
C) Compute P(A and S) and P(Pa and S).
D) Compute P(N) and P(N/A).

1. L  || m - Given in the question

2. ∠ 1 ≅ ∠ 3 -  Since L || m, we can see in the image that ∠1 is corresponding to ∠3 since corresponding angles are the angles which occupy the same relative position at each intersection where a straight line crosses two others

3. ∠1 ≅ ∠2  -  From the image, we can see that ∠1 is vertically opposite to ∠2, Hence ∠1 ≅ ∠2

4. ∠2 ≅ ∠3 -  From the image, we can see that ∠2 and ∠3 are alternate angles, since alternate angles are angles that are in opposite positions relative to a transversal intersecting two lines.

can you write an equivalent fraction for 5/9 and 1/10 using the least common denominator?

Answers

Answer: Yes

Step-by-step explanation:  

Rewriting input as fractions if necessary:

5/9, 1/10

For the denominators (9, 10) the least common multiple (LCM) is 90.

LCM(9, 10)

Therefore, the least common denominator (LCD) is 90.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

5/9 = 5/9 × 10/10 = 50/90

1/10 = 1/10 × 9/9 = 9/90

Cooper is a salesperson who sells computers at an electronics store. He makes a base pay amount of $ 60 per day regardless of sales and he earns a commission of 1.5% of the dollar amount of all sales that he makes. Write an equation for P, in terms of x, representing Cooper's total pay on a day on which he sells z dollars worth of computers.

Answers

Answer:

P = 0.015x + 60

Step-by-step explanation:

Since Cooper's base pay is $60, he would earn $60 even for selling $0 worth of computers, meaning P= 60 when x=0, which is the y-intercept.

(0,60) is a point on the graph

Since Cooper makes a commision of 1.5% for all sales, the amount of money earned in a given day increases $0.015 for each $1 of sales made (multiply 1 by 0.015). This means the slope of P is equal to 0.015.
