Answer:

x = 12

Step-by-step explanation:

The two marked angles are a linear pair, so are supplementary.

(8x -20)° +(8x +8)° = 180°

16x -12 = 180 . . . . . . . . . . . divide by °, collect terms

16x = 192 . . . . . . . . . . . add 12

x = 12 . . . . . . . . . . . divide by 16

In the center of a growing city is an old church and a high-rise office building separated by a plaza. Two surveyors are collaborating on the job of determining how high the tip of the church spire is above the plaza. Each surveyor has a theodolite mounted on a tripod. One surveyor is in the entrance way of the high-rise. The top of his tripod is 165cm above plaza level. The second surveyor is directly above the first, and (amazingly) the top of her tripod is exactly 100m above the top of her colleague's tripod. The first surveyor measures the angle of elevation of the tip of the spire as 50∘. The second surveyor measures the angle of depression of the tip of the spire as 30∘. (The diagram on the right is not drawn to scale. Points A and F are at plaza level. You'll have to supply all the necessary measurements on the diagram for yourself.)

Correct to 2 decimal places, how high is the tip of the spire above the plaza?

m∠ABU = 70°

Step-by-step explanation:

By applying angle addition postulate,

m∠ABC = m∠UBC + m∠ABU

145° = 75° + m∠ABU

m∠ABU = 145° - 75°

m∠ABU = 70°

Therefore, measure of angle ABU is 70°.

60 is 0.4% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 60 , slightly less than 60 , slightly greater than 60 , or a lot greater than 60 ? Explain.

Answers

Answer:

15000

Step-by-step explanation:

0.4%=0.004

0.004x=60

x=60/0.004

x=15000

The number 60 is 0.4 percentage of the number 15,000

Given data ,

To find the number that 60 is 0.4% of, we can set up the equation:

60 = 0.4 percentage of x

To solve for x, we need to convert 0.4% to its decimal form, which is 0.004:

0.004 * x = 60

Now we can solve for x by dividing both sides of the equation by 0.004:

x = 60 / 0.004

Dividing 60 by 0.004 gives us:

On simplifying the equation , we get

x = 15,000

Therefore, 60 is 0.4% of 15,000.

Since 0.4% is a very small percentage (less than 1%), we would expect the answer to be a lot greater than 60. This is because when a small percentage is applied to a number, the result will be significantly larger than the original number. In this case, the number that 60 is 0.4% of is 15,000, which is a lot greater than 60.

Anthony is a high school basketball player. How many points would Anthony score in a game if he made 8 three point shots and 2 two point shots? How many points would Anthony score in a game if he made xx three point shots and yy two point shots?

Answers

Answer:

try 6

Step-by-step explanation:

because it says 8 three point shots and 2 two point shots so its 3 times 2 ig

Answer:

Anthony would score 28 points.

If he made x 3 point shots and y 2 point shots = x*3 + y*2

Step-by-step explanation:

With Anthony making 8, 3 point shots you take 8 and multiply it by 3. This gives you 24. The 2, 2 point shots he made gives you 2 multiplied by 2 which gives you 4.

So taking x*3 + y*2, plug 8 into the x and 2 into the y. This gives you 8*3 + 2*2 = 24

Which type of function is represented by the equation 6y=2(x−5)

Answers

The type of the function that is represented by 6y = 2(x - 5) is a linear function

What are linear functions?

Linear functions are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

How to determine the type of the function?

The equation of the function is given as

6y = 2(x - 5)

Divide both sides of the equation by 6

So, we have

y = 1/3(x - 5)

Open the bracket

y = 1/3x - 5/3

The form of the above equation is

y = mx + c

The equation represented by y = mx + c is a linear function

Hence, the type of the function that is represented by 6y = 2(x - 5) is a linear function

Aiko is selling books for $12 each. She wants to make more than $180 in book sales. The inequality 12b > 180 can be used to determine the number of books, b, she must sell in order to meet her goal. Which number line best represents the solution to the inequality?For which equation is x=5 a solution?

Answers

The third number line shows the inequality.

What is Inequality?

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

Aiko is selling books for $12 each. She wants to make more than $180 in book sales.

and, the inequality 12b > 180 can be used to determine the number of books, b.

Now, solving the inequality

12b > 180

b > 180/12

b > 15

Hence, the third number line shows the inequality.
