Find the area
Please help!!!
Answer:
area of the semicircle=
diameter²=9²+21.6²
=81+466.56
diameter² =547.56
diameter=√547.56
=23.4
radius of the semicircle=diameter/2=23.4/2
=11.7
area of the semicircle=1/2πr²
=1/2×3.14×11.7²
=214.9173m²
area of the triangle=1/2×9×21.6
=97.2m²
area of the shaded region=214.9173m²-97.2m²
=117.7173m²
round it as possible

Electoral votes
Which statement best compares the spreads of the data sets?
Answer:
The interquartile range (IQR) for Democratic electoral votes, 186.5, is very nearly equal to the IQR for Republican votes, 185.5.
Step-by-step explanation:
The correct statement is; The interquartile range (IQR) for Democratic electoral votes, 186.5, is very nearly equal to the IQR for Republican votes, 185.5.
How to find the interquartile range?IQR(interquartile range) is the difference between third and first quartile.
[tex]IQR = Q_3 -Q_1[/tex]
The lower quartile, also called first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.
The third quartile (also called upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.
From the given plots, we have:
Republican
[tex]IQR = Q_3 -Q_1[/tex]
IQR = 356 - 170.5
IQR = 185.5
Democratic
[tex]IQR = Q_3 -Q_1[/tex]
IQR = 367.5 - 181
IQR = 186.5
Hence, The interquartile range (IQR) for Democratic electoral votes, 186.5, is very nearly equal to the IQR for Republican votes, 185.5.

1,024(0.50)^x That is the answer......................................
Divide.
(2x2 + 13x + 9) = (x + 7)
I think the right question, should be like this,

Determine side x. Round to the nearest unit. 20 9 12 5
Answer:
12
Step-by-step explanation:
First, you will have to use trigonometry. Since the side of the triangleis the opposite of the angle 53 and the hypotenuse, you will use sin.
Sin 53 degrees = opposite side / hypotenuse side.
The opposite side is x and the hypotenuse side equals 15.
sin53= x/15
15 ( sin 53 ) =x
x= 11.97953
Round
x=12

x² + 10x - 24
factors of 24 are: 1x24, 2x12, 3x8, 4x6
the pair I would select would be 2 and 12 as they could result in 10
(x + 12)(x - 2) = 0
Carmella likes to hike for more than 4 hours but less than 6 hours. She hikes at a speed of 2 miles per hour.
If m is the number of miles Carmella likes to hike, which inequality is true?
A. 0.33
B 2.0
C 4.0
D 6.0
E 8.0
Answer:
Guys the answer is E. I just took the test.
Step-by-step explanation:
Short answer: Look at the inequalities and plug in either 10 or 8 for m and then you're all set :)
Long Answer:So what you should do first is calculate how long she hikes for and how many mph. It says that she likes the hike for more than 4 hours but less than six. She also hikes at least 2 mph. So if you were ever in first grade you would know that she hikes for at least 5 hours. Now 5 x 2 is 10. Now you can either plug 8.0 into the inequalities or 10 but either way its going to be more than whatever number is first in the inequality but less than 12.

One number is 2 more than another number. If the product of the two numbers is 35, what are the numbers? Please show the work
Answer: 5 and 7.
Step-by-step explanation: I’m sorry I don’t know what kind of equation to do but I’ll show how I got the answer if that’s what you mean.
First I made a list of numbers that when multiplied equal 35
Then I went through the list and took out all the options that were not one number being 2 more than the other.
The only option left is 5 x 7 (5*7)
what kind of equation do you want? Like 5*7 = 35 and 5 + 2 = 7?
The numbers are 5 and 7.
What is equation?A mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
let the first number be 'x'
another number = x+2
According to question,
x(x+2)= 35
x²+2x-35=0
x²+7x-5x-35=0
x(x+7)-5(x+7)=0
(x-5)(x+7)=0
x= +5, -7
Hence, the numbers are 5 (x) and 7 (x+2).

When sampling is done with replacement, then events are considered to be independent, meaning the result of the first pick will not change the probabilities for the second pick. Without replacement: When sampling is done without replacement, each member of a population may be chosen only once.
Which answer represents the series in sigma notation? −7+(−2)+3+8+13 ∑j=15(5j−12) ∑j=15(−8j+1) ∑j=15−5(15)j−1 ∑j=155j−1
Answer:
∑j=15(5j−12)
Step-by-step explanation:
For j = 1 up to j = 5
j = 1
(5j - 12) = (5(1) - 12) = 5 - 12 = - 7
j = 2
(5j - 12) = (5(2) - 12) = 10 - 12 = - 2
j = 3
(5j - 12) = (5(3) - 12) = 15 - 12 = 3
j = 4
(5j - 12) = (5(4) - 12) = 20 - 12 = 8
j = 5
(5j - 12) = (5(5) - 12) = 25 - 12 = 13
(-7 + (-2) + 3 + 8 + 13)

HELP ME ASAP!!! On a scale used on a map, 3/4 inch represents 8 feet. On the map, what is the length of a room with an actual length of 24 feet?
A
4 in.
B[tex]1 \frac{3}{4} [/tex]
C
[tex]4 \ \frac{1}{2} [/tex]
D
[tex]2 \ \frac{1}{4} [/tex]
Answer:
D. 2 1/4
Step-by-step explanation:
3/4 inch = 8 feet
24 divided by 8 = 3
(meaning you would multiply eight three times in order to get to 24)
So....
3/4 x 3 = 2 1/4
Answer: 2 1/4
Hope this helps :)
Answer: D - 2 1/4”
Step-by-step explanation:
8 feet goes into 24 feet 3 times
Eg. 24/8 = 3
If 3/4” = 8 feet, then 3 x 3/4” = 24 feet
3 x 3/4” = 2 1/4”

need cos A and tan A asap please
Answer:
[tex]\sin A=\frac{12}{37},\\\\\cos A=\frac{35}{37},\\\\\tan A=\frac{12}{35}[/tex]
Step-by-step explanation:
In a right triangle only, the sine of an angle is equal to the angle's opposite side divided by the hypotenuse of the triangle. (o/h)
The cosine of the angle is equal to the angle's adjacent side divided by the hypotenuse of the triangle. (a/h)
The tangent of the angle is equal to angle's opposite side divided by the adjacent side. (o/a)
In this case, angle A's opposite side is 12, its adjacent side is 35, and the hypotenuse is 37 (o=12, a=35, h=37).
Thus we have:
[tex]\sin A=\frac{12}{37},\\\\\cos A=\frac{35}{37},\\\\\tan A=\frac{12}{35}[/tex]
Answer:
Step-by-step explanation:
sin A=opposite/hypotenuse=12/37
cos A=adjacent/hypotenuse=35/37
tan A=opposite/adjacent=12/35
