Answer:

16)

q / 12 = sin 20
q = 12 sin 20
q = 4.1

p / 12 = cos 20
p = 112 cos 20
p = 11.3

17)

x / 44 = tan 39
x = 44 tan 39
x = 35.6

35.6 / y = sin 39
y = 35.5 / sin 39
y = 56.4

18)

14 / b = sin 57
b = 14 / sin 57
b = 16.7

a / 16.7 = cos 57
a = 16.7 cos 57
a = 9.1

Please help me I dont know the answer

Okay so the range is the largest number - the smallest number.

So 25 - 11 = 14

The Absolute Mean Deviation is going to be a bit harder to explain, just go with it.

So we first calculate the mean.

119 ÷ 7 = 17

Now we calculate the distance each value is from 17. (SEE ATTACHMENT)

What happens next is that you take those values that are the distance from 17 and you add those up and calculate the mean of that.

28 ÷ 7 = 4

The Absolute Mean Deviation is 4.

I'll figure out the bottom in a minute. But this is all I got for you so far.

Vocabulary How can you tell when an equation in one variable has infinitely many solutions or no solution? When you solve for th

mart [117]

Answer: Choice C) When you solve for the variable, you will end up with a false statement, like 0 = 2, for an equation with no solution. You will end up with a true statement, like 2 = 2 for an equation with infinitely many solutions.

For example, let's say we had the equation x = x+2. Subtracting x from both sides leads to 0 = 2 which is a false statement. No matter what we replace x with, the equation x = x+2 is always false. That's why we don't have any solutions here.

For an equation like x + 2 = x + 2, subtracting x from both sides leads to 2 = 2 which is always true. A true equation is one where the same number is on both sides. No matter what we replace x with, the equation will be true. Therefore, there are infinitely many solutions.

I don’t get it! It says “Match each division expression to it’s quotient.” So can anyone help with 1/12 / 1/6 ? Please!

natta225 [31]

We have two fractions being divided. When we divide two fractions, we flip the second fraction and multiply

1/12 divided by 1/6 = 1/12 * 6/1

-------

From here we multiply straight across.

The numerators multiply to get 1*6 = 6

The denominators multiply to 12*1 = 12

We end up with 6/12 which reduces to 1/2 when you divide both parts by the GCF 6

<h3>Final Answer: 1/2</h3>

PL has endpoints P(4, −6) and L(−2, 1). The segment is translated using the mapping (x, y) → (x 5, y). What are the coordinates

cestrela7 [59]

The coordinates of P' is (9, -6) and L' is (3, -1).

<h2>Given that</h2>

PL has endpoints P(4, −6) and L(−2, 1).

The segment is translated using the mapping (x, y) → (x + 5, y).

<h3>We have to determine</h3>

What are the coordinates of P’ and L’?

<h3>According to the question</h3>

PL has endpoints P(4, −6) and L(−2, 1).

The segment is translated using the mapping (x, y) → (x + 5, y).

The coordinates of point P after translation using mapping is,

$\rm P(x, \ y) - P'(x+5, y)\\
\\
P(4, -6) - P'(4+5, \ -6)\\
\\
P(4, -6) - P'(9, -6)\\$

And the coordinates of point L after translation using mapping is,

$\rm L(x, \ y) - L'(x+5, y)\\\\L(-2, 1) - L'(-2+5, \ -1)\\\\L(4, -6) - L'(3, -1)\\$

Hence, The coordinates of P' is (9, -6) and L' is (3, -1).

Hardy has three times as many tennis balls as kerns. They have 940 tennis balls in all. How many tennis balls does Hardy have th

topjm [15]

Answer:

Hardy has 470 more tennis balls than Kerns.

Step-by-step explanation:

Given that:

Total number of tennis balls = 940

Let,

x represents the number of tennis balls Hardy has.

y represents the number of tennis balls Kerns has.

According to given statement,

x+y=940 Eqn 1

x = 3y Eqn 2

Putting x = 3y in Eqn 1

3y+y=940

4y=940

Dividing both sides by 4

$\frac{4y}{4}=\frac{940}{4}\\y=235$

Putting y=235 in Eqn 2

x = 3(235)

x = 705

Difference = Hardy's tennis balls - Kerns' tennis balls

Difference = 705 - 235 = 470

Hence,

Hardy has 470 more tennis balls than Kerns.
