Find cos x by dividing both sides of this equation by 4:

cos x = 3/4 = 0.75

Using a calculator's inverse cosine function, find x:

The measures of the three angles of a triangle are given by x+4,x, and 2x. What is the value of x

Answers

Answer:

x = 44°

Step-by-step explanation:

The sum of all the interior angles of a triangle = 180°

so:

(x+4) + x + 2x = 180°

reducing:

4x + 4° = 180°

4x = 176°

x = 44°

3) A drawer contains 10 blue pens, and 10 red pens. Without looking, Mrs.
Stanton is going to take one pen from a drawer, use it, and then put it back in
the drawer. Then he is going to take another pen from the drawer to use. What
is the probability of Mrs. Stanton taking a red pen first and then taking a blue
pen? P(red, then blue)?

Answers

The probability is 1/2 because he has an even amount of both colored pens so there are 50% blue and 50% red the odds are like flipping a coin in the air. There is a 50% chance that it will land on either heads or tails in other words 50/100 which is also 1/2 same thing applies with the pens.

Answer: 1/2

20% of _____ is 11

_____% of 60 is 21

(fill the blank)
(they're both seperate questions)

Answers

the first one is 55 and then the second one would be 35%

The first is 55, the second is 35%

Percent (as a decimal) x whole = part
0.2 x w = 11
w = 11/0.2
w = 55

p x 60 = 21
60p = 21
p = 0.35 = 35%

Giorgio is learning to play the piano. By the end of each month, he has learned 3 new songs.

Part A Graph 5 points on the coordinate plane below that show the total number of songs Giorgio has learned by the end of each month from month 1 to month 5.

Which equation represents the relationship between the independent variable, x , and the dependent variable, y?

Answers

Answer: y = 3x

Step-by-step explanation:

The answer is y=3x because every month Giorgio learns a new song. so for the first month they learned 3 songs and in the second month they learn 3 more that adds up to 6 song total, so if you just times the month by 3 you will get your answer.

Answer

the way you have it there is right for the giorgio and for the second one it will be x=3x

find the value of x.

Answers

x = 31

180 = 3x + 25 + 2x
180 = 5x + 25
-25. -25
155 = 5x
x = 31

Answer:

x=31

Step-by-step explanation:

Hello there!

the shown angles are supplementary meaning that the sum of the two is 180

so we create an equation

180=3x+25+2x

step 1 combine like terms

3x+2x

now we have

180=25+5x

step 2 subtract 25 from each side

180-25=155

now we have

155=5x

step 3 divide each side by 5

155/5=31

5x/5=x

we're left with x=31

A trampoline park costs $12 for the first hour and $6 for each additional hour. Flynn pays $30 at the trampoline park. Select the equation that represents the given situation and find the number of additional hours Flynn stays at the trampoline park after the first hour.
A. 12x + 6 = 30; 3 hours
B. 6x + 12 = 30; 3 hours
C. 6x + 12 = 30; 2 hours
D. 12x + 6 = 30; 2 hours

Answers

Answer is B. 12 dollers for 'admission' and then you have 6 per hour of time

The equation that represents the given situation is 12 + 6x = 30.

The number of additional hours is 3.

Option B is the correct answer.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

A trampoline park costs $12 for the first hour and $6 for each additional hour.

Amount paid at the park = $30

Now,

12 + 6x = 30

x is the number of hours.

Solve for x.

12 + 6x = 30

6x = 30 - 12

6x = 18

x = 3

Thus,

The equation is 12 + 6x = 30.

The number of hours is 3.

Write an equation in point-slope form of the line that passes through the point (5, 1) and has a slope of -3

Answers

Answer:

y - 1 = -3(x - 5)

Step-by-step explanation:

An equation in point-slope form of the line that passes through the point (x₁,y₁) and has a slope of m:

y - y₁ = m(x - x₁)

m = -3

(5, 1) ⇒ x₁ = 5, y₁ = 1
