Your answer is going to be: 21.

Step-by-step explanation:

In this problem, we're going to be using PEMDAS.

Answer:

8π units²

Step-by-step explanation:

Area of the circle can be defined as pi 'π' times  the radius squared 'r²'

A= πr²

radius given is 4 (see attachment for the figure)

r=4

A = π4²

A= 16π

Now, if you look at the figure, you can see that the shaded area of the circle is 'half' of the whole circle.

We will half the Area which we have found it above in order to determine the area of shaded sector

Therefore,

area of the shaded sector =  16π/2 => 8π units²

Answer: OPTION 1

Step-by-step explanation:

For this exercise you need to remember that, by definition, the Arc length can be calculated with the following formula:

[tex]arc\ length=rC[/tex]

where "C" is the central angle of the arc in radians and "r" is the radius.

Since you need to find the Central  angle, you have to solve for "C" from that formula, as following:

[tex]C=\frac{arc\ length}{r}[/tex]

According to the information given in the exercise, you can identify that:

[tex]arc\ length=100\ m\\\\r=60\ m[/tex]

Therefore, the final step is to substitute these values into the formula and evaluate, in order to find the value of "C":

[tex]C=\frac{100\ m}{60\ m} \\\\C=\frac{5}{3}\ rad[/tex]

Answer:

The projected cost of a gallon of oil by next june is $19.60.

Step-by-step explanation:

Given:

Oil prices are projected to increase by 100% by next june.

A quart of oil currently costs $2.45.

Now, to find the cost of a gallon of oil next june.

So, to get the projected cost of a quart of oil by next june:

Cost of one quart of oil currently = $2.45.

Rate of oil prices projected to increase by = 100%.

[tex]100\%\ of\ \$2.45+\$2.45\\\\=\frac{100}{100}\times 2.45+2.45\\\\=2.45+2.45\\\\=\$4.90.[/tex]

Now, to get the projected cost of a gallon of oil by next june we use conversion factor:

4 quart = 1 gallon.

If, 1 quart oil price = $4.90.

Then, 4 quarts oil price = [tex]\$4.90\times 4[/tex] = [tex]\$19.60.[/tex]

Thus, 1 gallon oil price = $19.60.

Therefore, the projected cost of a gallon of oil by next june is $19.60.

Step-by-step explanation:

f(4)= 16.

The answer is **C) 16**.

Here's how to evaluate the piecewise function f(4):

1. **Identify the appropriate rule:**

  - Since 4 is greater than 2 (4 > 2), we'll use the second rule of the function: f(x) = 5x - 4.

2. **Substitute x = 4:**

  - f(4) = 5(4) - 4

3. **Simplify:**

  - f(4) = 20 - 4 = 16

Therefore, f(4) = 16.

The other options are incorrect because they either use the wrong rule (A and D) or miscalculate the result (B).

Answer:

B(5,2)

Step-by-step explanation:

The mathematics question involves proving two triangles congruent in geometry, likely using congruence criteria such as SSS, SAS, or ASA, with the given information that line QR is parallel to PT.

The subject of this question is Mathematics, specifically it involves geometry and the proof of congruent triangles. The statement 'QR I PT' suggests that line QR is parallel to line PT. To prove triangles APQR and ATSR are congruent, one would need to demonstrate that they satisfy the criteria for congruence such as side-side-side (SSS), side-angle-side (SAS), or angle-side-angle (ASA). The angles mentioned, such as ∠QPR and ∠QRP, are likely parts of the required congruence criteria. However, additional information and a specific criteria of congruence need to be applied in a step-by-step explanation.

Answer:

d = 5

Step-by-step explanation:

The common difference d is the difference between consecutive terms in the sequence

- 29 - (- 34) = - 29 + 34 = 5

- 24 - (- 29) = - 24 + 29 = 5

- 19 - (- 24) = - 19 + 24 = 4

Thus the common difference is d = 5

The common difference between consecutive terms in the given sequence is 5.

The given sequence is {-34, -29, -24, -19, ...}

To find the common difference, we need to look for a pattern between consecutive terms. So, let's observe the differences between consecutive terms:

-29 - (-34) = 5

-24 - (-29) = 5

-19 - (-24) = 5

As we can see, the common difference between consecutive terms is 5.

The question is about calculating the price of guitar lessons after a 10% discount and the answer explains the steps to calculate the discounted price.

The subject of this question is Mathematics and the grade level is High School.

To calculate the amount after the discount, subtract 10% of $70 from $70. 10% of $70 is $7, so the discounted price is $70 - $7 = $63.

Therefore, Yoona gives a 10% discount to students which means the price per session is $63.

Answer:

12^3/12^7= 1/12^(7-3)= 1/12^4

Step-by-step explanation:

The solution to the problem '12 to the power of 3 over 12 to the power of 7' is 12 to the power of negative 4 or written as a fraction, it is 1 over 12 to the power of 4 or 1 over 20736.

The expression 123 over 127 refers to the mathematical concept of 'division of exponentials with the same base'. The rule in this case is to subtract the exponents. Therefore, 123 over 127 simplifies to 12-4. This can be understood as 1 over 124, or further simplified, 1 over 20736 if you multiply out the exponent.

Answer:

$115.50

Step-by-step explanation:

Answer:

width is 25 inches

length is 31 inches

Step-by-step explanation:

We will need the formula for perimeter of a rectangle:

P = 2(l + w)

"l" is length, "w" is width

If the length exceeds the width by 6, then:

l = w + 6       <= Substitute this into the equation

P = 2(l + w)

P = 2(w + 6 + w)

Remember we also know the perimeter is 112:

112 = 2(w + 6 + w)

Collect like terms:

112 = 2(2w + 6)

Start isolating "w" to find width.

56 = 2w + 6             Divided both sides by 2

50 = 2w                    Subtracted 6 from both sides

25 = w                      Divided both sides by 2

w = 25                      Variable on left for standard formatting

The width is 25 inches.

Find the length using "length exceeds width by 6".

l = w + 6

l = 25 + 6            Substitute the width

l = 31

The length is 31 inches.

∴ The length is 31 inches and the width is 25 inches.

Check your answer with the perimeter formula.

P = 2(l + w)

112 = 2(31 + 25)      Substitute all the variables.

112 = 2(56)

112 = 112               Same answer

LS = RS                Left side equals right side

The answer is correct.

Answer:

2.26 meters

Step-by-step explanation:

so the volume for a cylinder is

v= π r² x h

now just substitute in the numbers you know:

180= π r² x 11.25

now rearrange the formula:

180= r² x 11.25π

(rearranging allows you to do this next bit with ease)

now divide by 11.25π on both sides to get

[tex]\frac{180}{11.25\pi }[/tex]= r²

to maintain accuracy, don't divide yet

now you know what r² is but you want r, so square root it:

[tex]\sqrt{\frac{180}{11.25\pi } }[/tex]=r

Answer:

(x+11) by (x+10)

Step-by-step explanation:

We know that Area = Length x width

Given: Area = x²+9x+20

Lets sort this out first

Area = x²+5x + 4x + 20

Area = x(x+5) + 4(x+5)

Area = (x+5) (x+4)

Therefore, it is concluded that:

Length 'l' = (x+5) feet

Width 'w' = (x+4) feet

if a 3-foot walkway is built around the fountain, we'll add 3 feet on both sides

Therefore,

Outer Length = (x+5+3+3) = (x+11) feet

Outer Width = (x+4+3+3) = (x+10) feet

Answer:

The fountain is (x+5) by (x+4).  

dimensions of the outside border of the walkway are (x+11) by (x+10)
