Answer:
Measure of the arc = 14.32°
Step-by-step explanation:
Radius of a circle = 4 cm²
Area of the circle = πr²
Here, r = radius of the circle
Area of the circle = π(4)²
= 16π cm²
= 50.265 cm²
Since, area of a sector = [tex]\frac{\theta}{360}(\text{Area of the circle})[/tex]
Here, θ = Central angle subtended by the arc Or measure of arc
Area of the sector given as 2 cm²
2 = [tex]\frac{\theta}{360}(50.265)[/tex]
θ = 14.32°
Therefore, measure of the arc = 14.32°.
If you had a right triangle with legs measuring 40 yards and 100 yards long,
what would be the length of the hypotenuse? Round your answer to the
nearest yard if necessary. *
70 yd
92 yd
108 yd
146 yd
9514 1404 393
Answer:
(c) 108 yd
Step-by-step explanation:
For hypotenuse c and legs a and b, the Pythagorean theorem tells you the relation is ...
c² = a² +b²
Solving for c, we have ...
c = √(a² +b²)
c = √(40² +100²) = √(1600 +10000) = √11600
c ≈ 107.70 . . . . yards
The length of the hypotenuse is about 108 yards.
Please help thank you :)
Answer:
Step-by-step explanation:
Angle 1 is equal to angle 3 because they are opposite each other so
Angle 1=43 degrees
Angle 1 and angle 2 have a sum of 180 degrees because they are adjacent to each other.
angle 2=180-43=137 degrees.
angle 2 and 4 are opposite each other so they are equal
angle 4=137 degrees.
Answer:
Angle 1 = 43°
Angle 2 = 137°
Angls 4 = 137°
Step-by-step explanation:
To get angle 1, l and m intersect and there are two angles which cause vertical opposite angles. When there are vertical opposite angles, both angles have the same degree. For angle 2, you need to find angle 1 and 3, after that you deduct both angle 1 and 3 from 360° which is the angle of whole figure. 360 - 43 - 43 = 274° for angle 2 and 4, since they're also vertically opposite angles, both 2 and 4 have the same angle. All you need to do to find 2 and 4 is 274 ÷ 2 = 137°.

To make 12 ounces of hot chocolate, 3 tablespoons of cocoa are needed. How many tablespoons of cocoa are needed to make 72 ounces of hot chocolate?
Answer:
18
Step-by-step explanation:
Use calculator to find the measure of angle A to the nearest tenth of a degree.
5.) sin(A) = 0.9903
6.) cos(A) = 0.6428
8.) tan(A) = 1.2851
9.) cos(A) = 1.2608
10.) sin(A) = 0.7777
11.) sin(A) = 1.8330
Answer:
82° ; 50° ; 52° ;domain error ;51° ; domain error
Step-by-step explanation:
Using a calculator :
sin(A) = 0.9903
A = sin^-1(0.9903) = 82.01 = 82°
6.) cos(A) = 0.6428
A = cos^-1(0.6428) = 49.99 = 50°
8.) tan(A) = 1.2851
A = tan^-1(1.2851) = 52.111 = 52°
9.) cos(A) = 1.2608
A = cos^-1(1.2608) = domain error
10.) sin(A) = 0.7777
A = sin^-1(0.777) = 50.98 = 51°
11.) sin(A) = 1.8330
A = sin^-1(1.8330) = domain error

pythagorean theorem: FIND X
Answer:
X²=5²+12²
X²=25+144
X²=169
X²=13²
X=13
Answer:
x = 13
Step-by-step explanation:
The first step to finding x is to apply the numbers to the Pythagorean Theorem.
The formula for the Pythagorean Theorem is a^2 + b^2 = c^2.
1. Now we have to put the known values in place of the letters.
a = 12
b = 5
c = x
2. Since the formula is squaring a, b, and c, we have to square the numbers too.
a = 12^2
b = 5^2
c = x^2
12^2, or 12 squared, is 144.
5^2, or 5 squared, is 25.
3. Next we have to add those two numbers.
144 + 25 = 169
4. Lastly, we have to square root 169
√169 = 13
Therefore, your answer is 13.
Hope this Helps!
Can someone help me I’m having trouble finding the area of the shaded region in each figure and round the answer to two decimal places and I have to use 3.15:(
Answer:
Step-by-step explanation:
Area of a Semi Circle
Area = 1/2 pi r^2
r = d/2
r = 3/2
r = 1.5
Area = 1/2 3.14 * 1.5^2
Area = 1/2 * 3.14 * 2.25
Area = 3.5325
Area of Rectangle
L = 12 Yd
W = 4 Yd
Area = L * W
Area = 12 * 4 = 48
Total Area = 51.5325
How did you compute sums of dollar amounts that were not whole numbers?
Answer:
$7.34
Step-by-step explanation:
To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal
$6 + $1 = $7
Remaining decimal : $1.34 - $1 = $0.34
$7 + $0.34 = $7.34

A right triangle has side lengths d, e, and f as shown below.
Use these lengths to find tanx, sinx, and cosx.
Answer:
tan x = [tex]\frac{f}{e}[/tex]
sin x = [tex]\frac{f}{d}[/tex]
cos x = [tex]\frac{e}{d}[/tex]
Step-by-step explanation:
tan x = [tex]\frac{opposite}{adjacent}[/tex]
tan x = [tex]\frac{f}{e}[/tex]
sin x = [tex]\frac{opposite}{hypotenuse}[/tex]
sin x = [tex]\frac{f}{d}[/tex]
cos x = [tex]\frac{adajcent}{hypotenuse}[/tex]
cos x = [tex]\frac{e}{d}[/tex]

You have only $5 bills and $10 bills in your pocket. If you have ten bills totaling $70, how many of each do you have?
Video club A charges $10 for membership and. $4 per movie rental. Video club B charges $15 for membership and $3 per movie rental. For how many rentals will be cost be the same at both video clubs? What is that cost?
Answer:
5 rentals for $30
Step-by-step explanation: *using y = mx + b*
Info Given:
Video Club A-
$10 (would be your b)
$4 (would be your x)
Video Club B-
$15 (would be your b)
$3 (would be your x)
HOW TO SOLVE:
Video Club A - y = 4x + 10
Video Club B - y = 3x + 15
Set them equal to eachother to solve for x!
4x + 10 = 3x + 15
- 10 - 10
4x = 3x + 5
-3x -3x
x = 5 rentals
Plug in the x into both or just one equation to find the price!
y = 4x + 10
= 4(5) + 10
= 20 + 10
y = $30

Expand and simplify (x − 3)(2x + 3)(4x + 5)
Answer:
8x³ - 2x² - 51x - 45
Step-by-step explanation:
Given
(x - 3)(2x + 3)(4x + 5) ← expand second/third factors using FOIL
= (x - 3)(8x² + 22x + 15) ← distribute
= x(8x² + 22x + 15) - 3(8x² + 22x + 15) ← distribute parenthesis
= 8x³ + 22x² + 15x - 24x² - 66x - 45 ← collect like terms
= 8x³ - 2x² - 51x - 45
Answer:
8x^3-2x^2-51x-45
Step-by-step explanation:
(x − 3)(2x + 3)(4x + 5)
(2x^2+3x-6x-9)*(4x+5)
(2x^2-3x-9)*(4x+5)
= 8x^3-2x^2-51x-45

x-y=3
2x-3y=-1
A- 2x-2y=-6
2x-3y=-1
B 2x-2y=6
2x-3y=-1
C -2x+2y=-3
2x-3y=-1
D 3x+3y=9
2x-3y=-1
Answer:
Step-by-step explanation:
In order for us to be able to find our answer, we need to show our work.
-3(x-y=3) → -3x + 3y = -9
+2x - 3y = -1
____________________________
-1x = -10
-1 -1
We need to divide -1 both sides in order for us to be able to find our x-value but there's more to this than just solving for X.
x = 10
x - y = 3
10 - y = 3
-10 -10
_________________
-y = -7
-1 -1
We need to divide -1 both sides in order for us to be able to find our y-value. Please note that each y is equivalent to an invisible 1.
y = 7
As a result, your answer will be B.

Answer:
2h + 10
Step-by-step explanation:
The question gives one the height of Tree A (8h - 1) and the height of Tree B (6h - 11). The problem asks one to find how much taller Tree A is than Tree B. This problem can be modeled using a simple subtraction problem, the height of Tree A, minus the height of Tree B. Remember to distribute the subtraction sign outside of the parenthesis, and only combine like terms;
(Tree A) - (Tree B)
= (8h - 1) - (6h - 11)
= 8h - 1 - 6h + 11
= 2h + 10
Since there was no numerical value given for the variable (h), nor any value which this expression is equal, the final answer is (2h + 10).
Brooke has a cylinder metal tin where he keeps his coins. The radius of the base is 5.5 inches and the height is 4 inches what is the area of a vertical cross section of the cylinder through the center of the base?
Answer:
44 square inches.
Step-by-step explanation:
radius of the base = 5.5 inches
height of the cylinder = 4 inches
The shape of the vertical cross section of the cylinder through the center of the base would give a rectangle with length of 2r, and its width is the height of the cylinder.
Area of the vertical cross section = height x diameter
diameter of the cylinder = 2r
= 2 x 5.5
= 11 inches
The diameter of the cylinder is 11 inches.
Area of the vertical cross section = 4 x 11
= 44 square inches.
The area of a vertical cross section of the cylinder through the center of the base is 44 square inches.
