Find the sin, cosine, and tangent of angle A. Give your answers as fractions in simplest forms.
Find BC
AC^2=AB^2+BC^2
20^2=16^2+BC^2
400=256+BC^2
BC=√(400-356)
BC=12
Use SOHCAHTOA
Sine A=12/20=3/5
COS A=16/20 =4/5
TAN A=12/16 =3/4
Find the diameter of the circle with a circumference of 80 feet. Use 3.14 for pi. Round your answer to the nearest tenth.
12.7 ft
25.5 ft
40.0 ft
50.9 ft
Answer:
Option B = 25.5 ft
Step-by-step explanation:
Circumference = 80 ft
C = 2πr
80 = 2 * (22/7) * r
80 = (44/ 7) * r
So, Radius (r) = 80 * (7/44)
= 12.72 Feet
--> Diameter = 2r = 2 * 12.72
= 25.45 Feet
Therefore, Answer = Option B = 25.5 Feet (Round off)

In the first year of a 10,000 investment the interest rate was 6%. All earned interest remained invested for the second year, and the interest rate increased to 7%. What was the percent increase of the entire investment after two years?
Answer:
13.4%
Step-by-step explanation:
First year:
$10,000*6% = $600
New balance = $10,600
Second Year:
$10,600*7% = $742
$10,600+ $742 = $11,342
Total Return:
Final Balance - Initial balance
$11,342 - $10,000 = $1,342
$10,000*x ÷ $1,342
x = $1,342/$10,000
x = 0.1342
0.134 = 13.4%
For 50 consecutive days, a process engineer has measured the weight of a component after it has been coated with special paint. Each day, she takes a sample of 10 components. The average across all 500 components is 45.343019 grams. The average range across all parts is 0.0076382 grams. When constructing an X-bar chart, what would be the centerline, and what would be the upper and lower control limits
Answer:
UCL (X-bar) = X mean+ (A2 x R-bar)
LCL (X-bar) = X mean -(A2 x R-bar)
Center line = Mean
A2 for sample size of 10 = 0.308
X mean = 45.343019
R bar = Average of range = 0.0076382
UCL (X-bar) =45.343019+(0.308*0.0076382) = 45.3453715656 grams
LCL (X-bar) = 45.343019-(0.308*0.0076382) = 45.3406664344 grams
Center line = Mean = 45.343019
Solve for the system of equations using elimination
Answer:
(-1,5)
Step-by-step explanation:
Solve the following system:
2 y + x = 9 | (equation 1)
2 y + 3 x = 7 | (equation 2)
Subtract equation 2 from equation 1:
( 2 y + x ) - ( 2 y + 3 x ) = 9 - 7
- 2 x = 2
x = - 1
Substitute into question 1:
2 y - 1 = 9
y = 5
Answer: x = -1 , y = 5

Chrissy buys a pack of candy and eats 2 pieces per day. Find how many she eats in two weeks
Answer:
In two weeks she eats 28 pieces
Step-by-step explanation
Lets say she ate one per day, if its asking you how many you ate in two weeks, that would be 14 candies. But if she ate 2 per day all you have to do is add 14+14 to find out how many she ate in two weeks.
Answer:28 candies
Step-by-step explanation:
So Chrissy eats 2 each day and we need to find how many candies she eats in two weeks also in weeks there is 7 days plus another week would be 14 basically convert the 2 weeks into days (7+7).Now we need multiply since she eats 2 each day how many candies she eats in two weeks also in week so 2 x 14 =28
Verified answer!Therefore,she eats 28 candies in 2 weeks

Answer:
=−1/2
=3/2
Step-by-step explanation:
Answer:
x = -1/2
x = 3/2
Step-by-step explanation:
4x² - 4x = 3
Subtract 3.
4x² - 4x - 3 = 0
Factor by grouping.
(2x + 1)(2x - 3) = 0
2x + 1 = 0
2x - 3 = 0
x = -1/2
x = 3/2

Step-by-step explanation:
given
6n - 10
Take 2 as common then
2 ( 3n - 5 )
hope it helps :)
Answer:
2(3n-5)
Step-by-step explanation:
You need to find the highest common factor (2 in this case).
When the word factorise is mentioned that means there has to be brackets in your answer.
After the highest common factor is found then divide the numbers by it. for example, 6÷2 and -10÷2.

Carpet is installed in the hallways of a building. The cost of carpet and installation is $32.50 per square yard. A total length of 432.0 feet of carpet 5.0 feet wide is required. What is the total cost of carpet and installation? (Number of square feet = length in feet × width in feet)
Answer:
[tex]Total = \$7800[/tex]
Step-by-step explanation:
Given
[tex]Cost = \$32.50[/tex] per square yard
[tex]Length = 432.0ft[/tex]
[tex]Width = 5.0ft[/tex]
Required
Determine the cost of carpet and installation
First, calculate the area of the carpet
[tex]Area = Length * Width[/tex]
[tex]Area = 432.0ft * 5.0ft[/tex]
[tex]Area = 2160ft^2[/tex]
Convert to square yard
[tex]Area = \frac{2160yd^2}{9}[/tex]
[tex]Area = 240yd^2[/tex]
The cost is then calculated as:
[tex]Total= Area * Unit\ Cost[/tex]
[tex]Total = 240 * \$32.50[/tex]
[tex]Total = \$7800[/tex]

Here's my previous one if you wanna see it though:
Answer:
A = 1280 in²
Step-by-step explanation:
We know that the volume of a cube is A = a³, where a is the length of one of the edges.
So, to find a:
a³ = 4096
a = ∛4096
a = 16 in
Now, we need to find the surface area of the square on the cube, where:
A = 6a², because we are making a box (that is empty inside).
However, we need to change the formula to:
A = 5a², because the problem says that there is no top (so there are only 5 squares)
A = 5(16)²
A = 1280 in²

For the given triangle the statement that is true for length x is -
x < 9
What are triangles?
Triangles are a particular sort of polygon in geometry that have three sides and three vertices. Three straight sides make up the two-dimensional figure shown here. An example of a 3-sided polygon is a triangle. The total of a triangle's three angles equals 180 degrees. One plane completely encloses the triangle.
The length of 1 side is = 5 units
The length of second side is = 4 units
A key geometrical concept that connects the lengths of a triangle's sides is the triangle inequality theorem.
It stipulates that the length of the remaining side must be greater than the sum of the lengths of any two sides of a triangle.
The triangle inequality theorem can be written out as follows if a, b, and c are the lengths of a triangle's sides:
b + c > a
a + c > b
b + a > c
Since the sum for the given triangle is 5 + 4 = 9
So, the third side must be less than 9.
Therefore, the inequality is x < 9.
