Find the mean: 60, 67, 71, 76, 80
Answer:
The mean is 70.8.
Step-by-step explanation:
Finding the arithmetic mean, or average, can be found by adding up all the numbers divided by the total count of those numbers.
So, we have :: 60, 67, 71, 76, 80.
These numbers added together = 354.
There are 5 numbers listed.
354 / 5 = 70.8.
find the measure of angle A
Step-by-step explanation:
The sum of angles in a triangle = 180°
Therefore,
(7x - 6)° + (5x - 10)° + 52° = 180°
Collect the like terms and add
7x + 5x - 6 - 10 + 52 = 180°
12x + 36 = 180°
12x = 180 - 36
12x = 144
x = 144 / 12
x = 12°
From the above diagram,
Angle A = 7x - 6
A° = 7(12) - 6
A° = 84 - 6
A = 78°

what is (-11/21)+9/21 simplified
Explanation:
Ignore the denominators for now.
The numerators -11 and 9 add up to -11+9 = -2
Then we place that result over the common denominator 21 to get the final answer -2/21
This trick only works if the denominators are all the same. If not, then you'll need to find the LCD first before you can add the fractions. Luckily, all of the denominators were the same at 21.
(-11/21)+9/21
= (-11+9)/21
= -2/21.ans...

Find the approximate side length of a square game board with an area of 173 in.
Answer:
13.15 in
Step-by-step explanation:
We know that to get area for a square is
Side x side = side ^2
(normally we would put an algebra for it, but i just write i like this so that it is easier to understand)
OK therfore I can say
Area = side ^2
173 = side ^2
When u bring a square over, it becomes square root
So...
Square root 173 = side
Side = 13.15in
Answer:
13.15 in
Step-by-step explanation:
the side length = √173 = 13.1529464..= 13.15 in.
Find the area of the shaded part of the figure if a = 7, b = 10, c = 3
Answer:
65
Step-by-step explanation:
First lets find the area of the bottom rectangle
area of the rectangle = length × breadth
= 10 × 3
= 30
now lets find the area of the the above triangle
area of triangle = [tex]\frac{1}{2}[/tex] × base × height
= [tex]\frac{1}{2}[/tex] × 10 × 7
= [tex]\frac{1}{2}[/tex] × 70
= 35
now add area of rectangle + area of tringle
= 30 +35
= 65
Write the equation for each of the following statements (Each one is worth 10 points): 1) Xavier is nine years younger than Yolanda. 2) Yolanda is seven years older than Zed. 3) The sum of the ages of Xavier and Yolanda is twenty-five.
9514 1404 393
Answer:
X = Y -9Y = Z +7X +Y = 25Step-by-step explanation:
We can let X, Y, and Z represent the ages of Xavier, Yolanda, and Zed, respectively.
1) X = Y -9 . . . . . . Xavier is 9 years younger than Yolanda
2) Y = Z +7 . . . . . Yolanda is 7 years older than Zed
3) X +Y = 25 . . . . the sum of ages of Xavier and Yolanda is 25
_____
Additional comment
The first equation can be substituted into the last to give 2Y-9=25 ⇒ Y=17. The other ages are easily computed once you know this. X=8, Z=10.

Hey there!
Random: The symbol “±” means plus-or-minus
2x(9^2 ± 1)
= 2x(9^2) ± 2x(1)
= 2x(81) ± 2x(1)
= 162x ± 2x
= 164x or -164x
Therefore, your answer is: 164x or -164x
