PLEASE HELP ME! I need this for a grade.

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

Answer: D) 12

Step-by-step explanation:

As you can see side A is 6 and side B is also 6 so side C must be 12

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

The value of B is =31 .

the value of b is 31

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

Answer:

1,024 ÷ by how many number of rounds= x

Answer:

1,024(0.50)^x That is the answer......................................

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.

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]

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]

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

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.

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).

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

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.

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.
