Answer:
14.4 square units
Step-by-step explanation:
Keep in mind that the area here is a fraction of the area of a full circle of radius 8.
(area of sector) = (fraction)(pi)(8)^2
The fraction is the given central angle (pi over 7) divided by 2pi:
pi 1
--------- * ----------- = 1/14
7 2pi
Multiply the formula (fraction)(pi)(8)^2 found above by this fraction:
area of sector = (1/14)(pi)(8)^2 = 14.4 square units
one angle of a right triangle measures 80 degrees. what is the measure of the other acute angle
Answer:
10 degrees
Step-by-step explanation:
Since a right angle is 90 degrees in total, to find the missing degree subtract 80 from 90.
90-80=10 degrees

3.5(10n + 2n - 9) = 178.5
Answer:
n= 5
Step-by-step explanation:
3.5 (10n + 2n-9) = 178.5
Divide 3.5 on both sides
10n + 2n -9 +51
Add like terms to get 12n
12n - 9 = 51
12n = 51 + 9
Add 51 and 9 to get 60
12n + 60
Divide 60 by 12 to get 5
n=5
find the distance between each pair of points (-3,4) (2,6)
Answer:
≈ 5.4 units
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 3, 4) and (x₂, y₂ ) = (2, 6)
d = [tex]\sqrt{(2+3)^2+(6-4)^2}[/tex]
= [tex]\sqrt{5^2+2^2}[/tex]
= [tex]\sqrt{25+4}[/tex]
= [tex]\sqrt{29}[/tex]
≈ 5.4 ( to 1 dec. place )
How do you do the Pythagorean Theorem? Also how do you do it with one leg and hypotenuse? Also how do you do it with 2 legs and no hypotenuse?
Answer:
Pythagorean Theorem = a^2 + b^2= c^2
Step-by-step explanation:
(3)^2+ (4)^2 = C
3^2= 9
4^2= 16
9+16=25
(2 legs no hypotenuse)
9^2+ b^2=7^2
9^2 = 81
7^2= 49
81-49= 32
(you have to sqaure root it because the oppsite of sqaured is sqaured root)
32 squared = 5.657
and rounded is 5.7

Question 3 (10 points) (08.03/08.05 MC) A pair of equations is shown below:
y = 7x - 8
y = 5x – 2
Part A: Explain how you will solve the pair of equations by substitution or elimination. Show all the steps and write the solution. (5 points)
Part B: If the two equations are graphed, at what point will the lines representing the two equations intersect? Explain your answer. (5 points)
Answer:
part A) rearrange the equations to form simultaneous equations:
y-7x=8
y-5x=-2
now eliminate the y values by minusing the two equations:
(y-7x=8)-(y-5x=-2)
to get:
-2x=-6
x=3
now substitute x into one of the equations to get y:
y=5x-2
y=15-2
y=13
[tex]x = 3 \\ y = 13[/tex]
part B) the lines will intercept at (3, 13)

Step-by-step explanation:
[-1, 0] times [0, -3, 5]
[0, -1] [0, 1, 2]
hopefully this makes sense.
The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
How to rotate the triangle?The coordinates of the triangle are given as:
[tex]\left[\begin{array}{ccc}0&-3&5\\0&1&2\end{array}\right][/tex]
The rotation is given as:
180° counterclockwise about the origin.
The rule of 180° counterclockwise about the origin is:
(x,y) ⇒ (-x,-y)
Using the above rule, we have:
[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]
Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

To find the monthly difference in median income find the median income of a woman with a bachelor's degree and one without it then subtract. To find the hourly difference find the hour income of women and men with an advanced degree and then subtract.
What is the median?The median refers to the value that is placed right in the middle of other values. For example, if the values are 5, 9, 4 the median is 9.
How to solve the first question?This question requires you to:
Find the median of a woman with a bachelor's degree and one with only high school and some college. To do this look for the values placed in the middle.Subtract both values.How to solve the second question?This quetion requiers you to:
Find the hourly income of a man and a woman with an advanced degree. To do this divided the week or monthly income into the number of hours they work.Subtract the two results to find the difference.Note: This question is incomplete because there is no information provided about women's income; due to this, I answered based on general knowledge.

In the figure to the right, if AC = 21 and BC = 18, what is the
radius?
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82

Sia sells large candles for $3 each and small candles for $2 each. She sold 17 candles for $46.00. How many of each size candle did she sell? 4 small and 13 large candles 5 small and 12 large candles 12 small and 5 large candles 13 small and 4 large candles
Answer:
The number of large size candles sells are 12 and the number of small size candles are 5 .
Step-by-step explanation:
As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y. Equation becomes
x + y = 17
3x + 2y = 46
Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .
3x - 3x + 2y - 3y = 46 - 51
-y = - 5
y = 5
Put in the equation x + y = 17 .
x + 5 = 17
x = 17 - 5
x = 12
Therefore the number of large size candles sells are 12 and the number of small size candles are 5

Terry has 3 pairs of pants (black, khaki, and brown) and 4 shirts (yellow, red, blue, and white). He does not care which colors he wears together. How many different outfits can Terry make
Answer: 12 different outfits
===========================================================
Explanation:
We simply multiply the values given to us. Think of a table that has 3 rows and 4 columns. The rows represent the different colors of pants Terry can wear. Each column is a different color shirt. Since we have 3 rows and 4 columns, we have 3*4 = 12 cells inside the table. Each cell represents a combination of pants and shirt colors. This means there are 12 different outfits possible.
Answer:
12
Step-by-step explanation:
if he has 3 pairs of pants and doesn't care what colors he wears then each shirt can go with the pants once and since there a 4 shirts and three pants then 3 times 4 =12

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?
Answer:
$135
Step-by-step explanation:
Given data
Amount paid for new surfboard= $81
Percentage of the savings paid= 60%
Let the amount of the savings be x
Hence
60% of x= 81
60/100*x= 81
0.6x=81
x= 81/0.6
x=$135
Hence his savings was $135
