Answer:
QR = 82.38 to nearest hundredth.
Step-by-step explanation:
As they are similar corresponding sides are in the same ratio.
So MN / QR = LM / QR
13/51 = 21/ QR
`3QR = 51*21
QR = 51*21/13
QR = 82.38
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

Which of the following is a factor of x2 + 10x -24
Answer:
b) (x + 12)
Step-by-step explanation:
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

How much money would you have if you invested $3000 at 6.25% annual interest, compounded daily for 2 years?
Answer:
[tex]A\simeq3399.41[/tex]
Step-by-step explanation:
The amount formula in compound interest is:
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
where:
P = principal amount
r = annual interest
n = number of compounding periods
t = number of years
We already know that:
P = $3000
[tex]r = 6.25\% = \frac{6.25\%}{100\%}=0.0625[/tex]
t = 2
n = 365
Then,
[tex]A=3000(1+\frac{0.0625}{365} )^{(365)(2)}\\\\A=3000(1+\frac{0.0625}{365} )^{730}\\\\A=3399.408982\\\\A\simeq3399.41[/tex]
pay:11.71 per hour
hours:11 hours per week
Answer:
$128.81 per week
$515.24 per month
$6182.88 per year
Step-by-step explanation:
[tex]\frac{11.71}{y} :\frac{1}{11}[/tex]
y = 128.81
[tex]\frac{128.81}{y} :\frac{1}{4}[/tex]
y = 515.24
[tex]\frac{515.24}{y}: \frac{1}{12}[/tex]
y = 6182.88
Divide.
(2x2 + 13x + 9) = (x + 7)
I think the right question, should be like this,
= 2x² + 13x + 9/x + 7
So, the quotient is 2x - 1 and the remainder is 16, you can find answer there in attachment.

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).

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.

The diagram shows a triangle.

The value of B is =31 .
the value of b is 31
Basic Ratio Right Triangle Trigonometry Find the missing side X and Y.
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
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
