Answer:
SA = 250 pi
SA = 785 in^2
Step-by-step explanation:
Givens
d = 10
h = 20
r = d/2
Formula
r = d/2
r = 10/2
r = 5
SA = 2*pi*r^2 + pi*d*h
Solution
SA = 2 * pi * 5^2 + pi * 10 * 20
SA = 2 * 25 *pi + pi * 200
SA = 50 pi + 200 pi
SA = 250*pi
This is one answer.
The second is 250 * 3.14
SA = 785 in^2

Find the area of the shaded sector. Leave your answer in terms of pie
ANSWER
The area of the shaded sector is
[tex]Area =\pi \: {in}^{2} [/tex]
EXPLANATION
The area of a sector is calculated using the formula,
[tex]Area = \frac{central \: angle}{360 \degree} \: \times \pi \: {r}^{2} [/tex]
Fro the diagram, the central angle is 90°
The radius of the circle is 2 in.
[tex]Area = \frac{90 \degree}{360 \degree} \: \times \pi \: {2}^{2} {in}^{2} [/tex]
[tex]Area = \frac{1}{4} \: \times \pi \: 4 {in}^{2} [/tex]
This finally simplifies to
[tex]Area =\pi \: {in}^{2} [/tex]
Answer:
Area of shaded region = 3.14 in²
Step-by-step explanation:
Formula:-
Area of circle = πr²
Where 'r' is the radius of circle
It is given a circle with radius 2 in.
To find the area of circle
Here r = 2 in
Area = πr² = 3.14 * 2² = 12.56 in²
To find the area of shaded region
Here central angle of sector = 90°
area of sector= (90/360) * area of circle
= (1/4)12.56 = 3.14 in²
d) What is the measure of ∠H? Explain. (1 point)
Answer:
105 degrees
Step-by-step explanation:
The measure of angle H from the given figure is 67.5 degree.
What is vertical angle theorem?Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.
Given that measure of angle F is 67.5°
The angles formed when two lines cross each other are known as vertical angles. Vertically opposite angles are the opposing angles created by these lines.
In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines.
From the given figure,
∠F=∠H (Vertically opposite angles are equal)
Angle F= Angle H=67.5°
So, angle H is 67.5 degree
Therefore, the measure of angle H is 67.5 degree.

Answer:
A. $3,992.50
Step-by-step explanation:
Pavi has a credit limit of $8,000.
The credit statement says that the current balance is $4,007.50.
The margin Pavi has is the limit ($8,000) minus the current balance ($4.007.50), so 8000 - 4007.50 = 3992.50
It could have been guessed easily, because the balance is roughly half of the credit limit... so what's left is roughly half of the credit limit. And the first answer is the only one close to that half-limit number ($4,000).
A farmer sells carrots and squash. A customer buys 1 pound of carrots and 1.5 ponds of squash for $7.00. Another customer buys 4.5 pounds of carrots and 1.75 pounds of squash for $14.00. Enter the price in dollars for 1 pound of carrots
Answer:
$1.75
Step-by-step explanation:
1 pound of carrot and 1.5 pounds of squash cost $7.00.
1c + 1.5s = 7 ----------------- [ 1 ]
4.5 pounds of carrot and 1.75 pound of squash cost $14.00.
4.5c + 1.75s = 14 ----------------- [ 2 ]
[ 1 ] x 4.5:
4.5c + 6.75s = 31.5 ----------------- [ 1a ]
[1a] - [2]:
5s = 17.5
s = $3.50
Sub s = 3.5 into [ 1 ]:
1c + 1.5 (3.5) = 7
1c + 5.25 = 7
1c = $1.75
By setting up and solving a system of linear equations based on the purchases made by two customers, we calculated the price of carrots to be $2.00 per pound.
Explanation:To determine the price per pound for carrots, we can set up a system of linear equations based on the provided information and solve it. Let 'c' represent the cost per pound of carrots and 's' represent the cost per pound of squash.
Equation 1: c + 1.5s = $7.00 from the first customer's purchase.Equation 2: 4.5c + 1.75s = $14.00 from the second customer's purchase.Multiplying Equation 1 by 3 gives us:
3c + 4.5s = $21.00Now, let's subtract Equation 2 from this new equation to eliminate 's' and solve for 'c'.
3c + 4.5s - (4.5c + 1.75s) = $21.00 - $14.00-1.5c + 2.75s = $7.00-1.5c = $7.00 - 2.75sSince 4.5c + 1.75s = $14.00, let's solve for 's'.1.75s = $14.00 - 4.5cs = ($14.00 - 4.5c) / 1.75Now we replace 's' in the -1.5c term:-1.5c = $7.00 - 2.75(($14.00 - 4.5c) / 1.75)-1.5c = $7.00 - (2.75 × $8.00) / 1.75 + (2.75 × 4.5c) / 1.75-1.5c + (2.75 × 4.5c) / 1.75 = $7.00 - $8.00c(4.5 × 2.75 / 1.75 - 1.5) = -$1.00c = -$1.00 / (4.5 × 2.75 / 1.75 - 1.5)Calculate the right side to find the price per pound for carrots.After calculating, we find that c = $2.00 per pound for carrots.
Which function is linear? A) f(x) = 8x2 + 2 B) f(x) = 8 x + 2 C) f(x) = 8x2 − 2 D) f(x) = x 8 − 2
Answer with Step-by-step explanation:
A linear function is of the form ax+b
A) f(x) = 8x² + 2
The above expression is not of the form ax+b
hence, it is not linear
B) f(x) = 8 x + 2
The above expression is of the form ax+b
hence, it is linear
C) f(x) = 8x² − 2
The above expression is not of the form ax+b
hence, it is not linear
D) f(x) = [tex]x^8-2[/tex]
The above expression is not of the form ax+b
hence, it is not linear
Hence, function which is linear is:
B) f(x) = 8 x + 2
Answer:
B)
Step-by-step explanation:
Assuming the numbers following the variables are exponents, (ex: 8x2, x8), the only function that is linear would be option B. This is because linear functions do not have exponents following their variables. If graphed, t are a straight line.

Boats from all along the Atlantic coast were moored at a busy marina one summer day. Of the 14 boats at the marina, 7 were from Rhode Island.
What is the probability that a randomly selected boat will be from Rhode Island?
Simplify your answer and write it as a fraction or whole number.
P(Rhode Island) =
The probability of selecting a boat from Rhode Island is 7 out of 14, which simplifies to 1/2, or 50%. There's an equal chance of picking a boat from Rhode Island as not.
Explanation:The probability of selecting a boat from Rhode Island at the marina is calculated by dividing the number of Rhode Island boats by the total number of boats.
There are 7 boats from Rhode Island and 14 boats in total.
Therefore, the probability is 7 out of 14, which simplifies to 1/2 when reduced.
This can also be written as a decimal, 0.5, or a percentage, 50%, indicating that there is an equal chance of selecting a Rhode Island boat as there is of selecting a boat from another place.
Thus, there's an equal chance of picking a boat from Rhode Island as not.
Final answer:
The probability that a randomly selected boat will be from Rhode Island is 1/2.
Explanation:
To calculate the probability that a randomly selected boat at the marina is from Rhode Island, we use the basic probability formula:
Probability (P) of an event = (Number of favorable outcomes) / (Total number of possible outcomes)
Given that there are 7 boats from Rhode Island and a total of 14 boats at the marina, the probability (P) that a randomly selected boat is from Rhode Island is:
P(Rhode Island) = 7 / 14 = 1/2.
Therefore, the simplified fraction representing the probability is 1/2.

Which of the following describes the parabola with the equation y=-x^2-3x+6
Step-by-step explanation:
use photomath for math problems and it give you step by step
Parabola defined by the equation y = -x² - 3x + 6 will be represented by the picture attached.
Equation of the parabola given in the question is,
y = -x² - 3x + 6
Convert this equation in the vertex form, [y = a(x - h)² + k, here (h, k) is the vertex of the parabola]
y = -x² - 2(1.5)x - (1.5)² + (1.5)² + 6
= -(x + 1.5)²+ (1.5)² + 6
= -(x + 1.5)² + 2.25 + 6
= -(x + 1.5)² + 8.25
From this equation vertex of the parabola will be (-1.5, 8.25).
Leading coefficient 'a' = -1 (negative)
y - intercept of the equation → y = -(0 - 1.5)² + 8.25
y = 6
x- intercept of the equation → 0 = -(x - 1.5)² + 8.25
(x - 1.5) = √8.25
x = 1.372, -4.372
Therefore, parabola will open downwards (a is negative), y-intercept (0, 6) and x-intercepts as (-4.372, 0), (1.372, 0) and vertex as (1.5, 8.25).

[tex]\frac{4}{4}total[/tex]
[tex]\frac{4}{4} - (\frac{2}{4} + \frac{1}{4} )[/tex]
[tex]\frac{4}{4} - \frac{3}{4} = \frac{1}{4}[/tex]
[tex]\frac{1}{4}[/tex] of the candy bar is remaining
1/4 of the candy bar is left.
First, let's add up the fractions of the candy bar that Jim and his brother ate:
Jim ate = 1/4
his brother ate = 2/4.
To find out how much they ate in total, we add these fractions:
1/4 + 2/4
= 3/4
So, they ate a total of 3/4 of the candy bar.
Now, to find out how much of the candy bar is left, we subtract the total amount they ate from 1 (the whole candy bar):
1 - 3/4
= 1/4
So, 1/4 of the candy bar is left.

Step-by-step explanation:
The length of side AC can be found by counting the squares between AC: 8.
The length of side BC can be found using the Pythagorean Theorem. B is 3 units to the right of C and 4 units above C. Thus:
|BC| = √(3² + 4²) = √25 = 5.
|AC| has the same length: 5.
Thus, the perimeter of this triangle is 5 + 5 + 8, or 18.
