Find the area of each sector

Mathematics
1 answer:
Bas_tet [7]3 years ago
7 0

First, let's take a look at the formula of a sector: θ/360° x 兀r^2

In this case:

=90°/360° x 兀13^2

=1/4 x 169兀

=169/4 兀

=42.25兀 sq. ft

Therefore the answer is 42.25兀 sq. ft.

Hope it helps!

Slav-nsk [51]

The regression equation based on the information given about the sugar contents will be 0.18x - 20.84.

<h3>How to explain the regression?</h3>

It should be noted that from the information, the accompanying data are the caloric contents and the sugar contents of 11 high-fiber breakfast cereals.

The sugar content will be:

a. 160 calories

= 0.18x - 20.84.

= 0.18(160) - 20.84

= 7.96

b. 90 calories

= 0.18x - 20.84.

= 0.18(90) - 20.84

= -4.64

c. 175 calories

= 0.18x - 20.84.

= 0.18(175) - 20.84

= 10.66

d. 208 calories

= 0.18x - 20.84.

= 0.18(208) - 20.84

= 16.6

Therefore, the sugar contents is illustrated above.

Paul bought a 15-year treasury bond for a face amount of $600. The 2.5% interest will be compounded quarterly. What will the fut
Alika [10]
First, we convert the interest such that it is compounded annually. The formula would be:

ieff = (1 + i/m)^m - 1
where m = 4, since there are 4 quarters in a year
ieff = (1 + 0.025/4)^4 - 1
ieff = 0.0252

Then we use this for this equation:
F = P(1 + i)^n, where F is the future worth, P is the present worth and n is the number of years
F = $600(1 + 0.0252)^15
F = $871.53

PLEASEPLEASE ANSWER
IRINA_888 [86]

Answer:

x = 7

Step-by-step explanation:

A triangle's total interior angle measurement will equal 180°.

Set all measurements equal to 180:

(82) + (9x - 6) + (6x - 1) = 180

Simplify. Combine like terms:

(82 - 6 - 1) + (9x + 6x) = 180

(82 - 7) + (15x) = 180

(75) + 15x = 180

Next, isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, Subtract 75 from both sides of the equation:

15x + 75 = 180

15x + 75 (-75) = 180 (-75)

15x = 180 - 75

15x = 105

Next, divide 15 from both sides of the equation:

(15x)/15 = (105)/15

x = 105/15

x = 7

7 is your value for x.

Michael thought he could read 23 pages of his book in class. He was only able to read 20. what is his percent error
Cerrena [4.2K]
Percent error is calculated using

((Actual - predicted) / actual) * 100

In this case, the actual value of the number of pages he read is 20. The expected value was 23. So simply plug in:

((20 - 23) / 20) * 100 = -15%
