Answer:

I Think The Answer Is 22 Feet???

Step-by-step explanation:

11. Angle A and B are supplementary (add to 180)

And measure of Angle A is 2x+30 and measure of angle B is 6x-12. All you have to do is make an algebraic expression.

180= (2x+30) + (6x-12)

Then just combine like terms and you get

8x+18=180.. Subtract 18 and you get

8x=162 then divide by 8 and you get

X=20.25

Then plug in the number and you get

180=(2*20.25+30)+(6×20.25-12)

Which is is transferred to

180=(70.5) +(109.5)

Which is 180=180.

The measure of angleA is 70.5°

You can try the other's if you want if not then

9. Value of x is 33.5

10. Measure of angleB 90°

12. Measure of angleA 24°

Answer:

Step-by-step explanation:

This is going to give you a preposterous answer. The width is into the millions.

density = 9000 kg / m^3

mass = 0.45 kg

V = density / mass

V = 9000 / 0.45 = 20000 m^3

V = L *w * h

L = 0.5 m

h = 0.01 m

w = ?

20000 = 0.5 * 0.01 * w

20000 / (0.5 * 0.01) = w

w = 4000000 m

Answer:

2/7

Step-by-step explanation:

Probability=number of names chosen/total number of names

p=2/7

Here in this question order is mentioned so we will use permutation.

and the formula is P(n,r) = [tex]\frac{n!}{(n-r)!}[/tex]

When the order of selecting something doesn't matter we use combination and when order of selection matters we use permutation.

In the given question number of unique names (n) = 7 and we are taking 2 names at a time.So the permutation of 7 names takes 2 at a time is P(7,2) =

[tex]\frac{7!}{(7-2)!}[/tex] = [tex]\frac{7!}{5!}[/tex] = [tex]\frac{7*6*5*4*3*2*1}{5*4*3*2*1}[/tex] = 7x6 = 56.

So, the number of ways of selecting is 56.

Answer:

[tex]\boxed {\boxed {\sf d=10}}[/tex]

Step-by-step explanation:

The distance between two points can be calculated using the following formula.

[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

In this formula, (x₁, y₁) and (x₂, y₂) are the two points. We are given the points (-9, -2) and (-3,6). If we match the value with the corresponding variable we see that:

Substitute the values into the formula.

[tex]d= \sqrt {(-3 - -9)^2 + (6 - -2)^2[/tex]

Solve inside the parentheses. Remember that 2 back to back negative signs become a plus sign.

[tex]d= \sqrt{ (6)^2 + (8)^2[/tex]

Solve the exponents. Multiply the number by itself.

[tex]d= \sqrt{(36)+(64)[/tex]

Add.

[tex]d= \sqrt{100[/tex]

Take the square root of the number.

[tex]d= 10[/tex]

The distance between the points (-9, -2) and (-3, 6) is 10.

Answer:

Step-by-step explanation:

The revenue function is given to you, it's just not given in equation form. In equation form, the function is

R(p) = p(120 - 4p)

If we are looking for the number of tickets that causes the revenue to be $0, we replace R(p) with 0 and solve for p.

0 = p(120 - 4p). That means, by the Zero Product Property, that

p = 0 or 120 - 4p = 0 which gives us, when we solve each one of those equations, that

p = 0 or

120 = 4p and

p = 30. The reasoning is the bold statement up above.

The equation we would use to determine the number of tickets needed to sell for the revenue to be $600 will be

600 = p(120 - 4p)

Answer:

3-gallon jug of water for $10.92, is the better buy

Step-by-step explanation:

First let's do the 3 gallon jug -

We need to find the unit rate (The cost per gallon/quart)

$10.92 / 3 = $3.64

$8.64 / 8 = $1.08

1 Gallon = 4 Quarts, therefore the 3-gallon jug of water is the better buy.

Answer:

see below

Step-by-step explanation:

To find the conjugate of a+bi take the opposite of bi so it would be a - bi

7-3i, the conjugate is 7 + 3i

8+2i  the conjugate is 8 -2i

The product of a number and its conjugate is

(a+bi) (a-bi) = a^2 +abi-abi -b^2 i^2 = a^2 - b^2 (-1) = a^2 + b^2

( 4-i) ( 4+i) = 4^2 + 1^2 = 16+1 = 17

( 6+3i)(6-3i) = 6^2 + 3^2 = 36+9 = 45

Answer:

14810 votes

Step-by-step explanation:

The canidate won, so that means that they were the 7 instead of the 5.

Then you divide 20734 by 7, to see how many votes were for each "1". That's 2962.

Now you know that every "1" is worth 2962. Since the other candidate got 5, you multiply 5 by 2962 which is 14810.

The other candidate got 14810 votes.
