Find the measure of angle A

Find The Measure Of Angle A

Answers

Answer 1

Answer:

45°

Step-by-step explanation:

The sum of interior angles in a triangle is equal to 180°

60 + x + 87 + x + 57 = 180 add like terms

2x + 204 = 180 subtract 204 from both sides

2x = -24 divide both sides by 2

x = -12

angle A is x + 57 so if we replace A with the value we found

(-12) + 57 = 45°

A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?

Answers

Answer:

t = 5 s

Step-by-step explanation:

The function that gives the height in feet of the ball t seconds after it is thrown is :

[tex]h(t)=-16t^2+48t+160[/tex]

We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.

So,

[tex]-16t^2+48t+160=0[/tex]

We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.

t = -2 s is not possible.

Hence, the ball will hit the ground before 5 seconds.

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs 20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in pounds can be represented by f(x) = 20x + 4.

Answers

Answer:

Range[4,24,44,64,84,104,124]

Step-by-step explanation:

CHECK THE COMPLETE QUESTION BELOW;

A set of weights includes a 4 lb barbell and 6 pairs of weight plates. Each pair of plates weighs

20 lb. If x pairs of plates are added to the barbell, the total weight of the barbell and plates in

pounds can be represented by f x( ) = 20x + 4.

What is the range of the function for this situation?

The range of a function can be defined as the difference between the maximum and minimum function. From the question, we can deduced that the minimum function of X is 0 and no plate is added, and the maximum is 6

The given function is

f(x) = 20x + 4 =

f(0) = 20(0) + 4

= 4

f(6) = 20(6) + 4

= 124

Which means the range is within 4 and 124.

But we are told from the question that Each pair of plates weighs 20 lb, which means there is difference of 20ib each between 4 and 24

Then we can compute the range as [4,124] or (4,24,44,64,84,104,124)

Tickets to the zoo cost $12 for adults and $8 for children. The school has a budget of $240 for the field trip. An equation representing the budget for the trip is 240=12x+8y. Here is a graph of this equation:

Answers

Answer:

18 children

Step-by-step explanation:

Given

[tex]240 = 12x +8y[/tex]

Required (missing part of the question):

Number of children that will be able to go to the zoo if 8 adult tickets are purchased

 

The graph is missing. However, the question can be solved without the graph.

From the question and equation, we can deduce the following:

x represents adultsy represents children

So, when 8 adult tickets were sold.

This means

[tex]x = 8[/tex]

Substitute 8 for x in [tex]240 = 12x +8y[/tex]

[tex]240= 12 * 8 + 8y[/tex]

[tex]240= 96+ 8y[/tex]

Subtract 96 from both sides

[tex]240 - 96 = 96 - 96 + 8y[/tex]

[tex]144 = 8y[/tex]

[tex]8y = 144[/tex]

Solve for y

[tex]y= \frac{144}{8}[/tex]

[tex]y= 18[/tex]

This means that 18 children will be able to go

Write the equation of the line that is perpendicular to y = 3x - r and that has the same y - intercept .

WILL MARK BRAINLIEST

Answers

Answer:

y= -(1/3)x -r

Step-by-step explanation:

a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.

In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.

The problem states the line has the same y-intercept so it has to still be -r.

So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

A softball team has 12 girls on it. The coach needs to arrange 9 girls for the batting order. If the lineup is selected at random, what is the probability that you will be the lead-off batter (the first person to bat)?

Answers

Answer: P = 1/12 = 0.083

Step-by-step explanation:

Out of the 12 girls, there will be only one that is the lead-off batter.

we can assume that this is the first being selected at random, then the probability that you will be the lead-off batter, is equal to the quotient between 1 (the outcome where you are selected) and 12 (the total number of outcomes)

Then the probability is:

P = 1/12 = 0.083

The fact that there will be an arrange of only 9 girls does not affect the probability of you getting the position of the lead-off batter.

find the gcf and use it to reduce 36/63​

Answers

Answer:

[tex]\frac{4}{7}[/tex]

Step-by-step explanation:

The greatest common factor of 36 and 63 is 9.

Thus, [tex]\frac{36}{63}[/tex] = [tex]\frac{4}{7}[/tex] since (36 ÷ 9 = 4) and (63 ÷ 9 = 7).

Answer:

4/ 7

Step-by-step explanation:

you list the factors of each number  so  factors of 36 are 1 2 3 4 6 9 12 18 36 and factors of 63 are 1 , 3 , 7 , 9 , 21 and 63  as the highest common factor in each number is 9 you do 36 ÷ 9 = 4 which will be the numerator and 63÷ 9 = 7 which will be the denominator so the simplest form of 36/63 is 4/7

i love these kind of questions :D

okay so lets write our problem down 1st:

(-3÷2)x-9=27

okay so you take one of your answers lets do A 1st and put is as x like this:

(-3÷2)-24x(-9)=27 now solve:

(think of PEMDAS)

P = perenthesis

E = exponents (which you dont have in this problem)

M = multiply

D = divide

A = add

S = subtract

do perenthesis 1st which would be (-3÷2)

(-1.5)-24x(-9)

now multiply 24x(-9)

(-1.5)-216 = (-214.5) does it equal -24 (which was what you plugged in for x)

no it doesnt so A cant be your answer. now do it for the rest of your answers :D

The slope is the same.

Parallel lines have completely opposite slopes!!
By this, positives become negatives, and negatives become positives, as well as being flipped.
3/7 would flip and become negative to become F, -7/3!

For future reference, this works with whole numbers too, like 3 becoming -1/3.

A recipe for blueberry muffins states that it yields 12 muffins, with 270 calories per muffin. You instead decide to make
mini-muffins, and the recipe yields 20 mini-muffins. If you eat 7 mini-muffins, how many calories will you consume?

Answers

Answer:

The calories you will consume are 1134 calories

Step-by-step explanation:

Let us solve the problem

∵ A recipe for blueberry muffins states that it yields 12 muffins, with 270

  calories per muffin

→ Find the total calories of the 12 muffins

∴ The total calories of them = 12 × 270

The total calories of them = 3240 calories

∵ You instead decide to make mini-muffins, and the recipe yields 20

   mini-muffins

→ That means the same amount of calories are in 20 mini-muffins, to find

   the calories of each one divide the total amount of calories by 20

∵ The calories per mini-muffin = 3240 ÷ 20

The calories per mini-muffin = 162 calories

∵ You will eat 7 mini-muffins

∴ The calories you consume = 7 × 162

The calories you will consume = 1134 calories
