Basically:
a.) All triangles' angles add up to 180°. Take all given values to set up an equation in which the sum is 180. Simplify and solve for x.
Result: x=12
b.) Insert the value of x into the given values of ∠A. Simplify.
Result: ∠A= 50°

When a quantity is increased or
decreased, what PERCENT describes the
original or starting value?
Answers
Answer:
100%
Step-by-step explanation:
The percentage that describes the original value we are calculating from is 100%
This represents the original value that we are working with.
For example if we are to decrease by 10%, it means we are to be left with 90%
If also we are to increase by 10%, it means that we are to be left with 110%

the volume of a large sphere (of radius R) is twice the volume of a smaller sphere (of radius r). form an equation linking r and R.
Answers
Step-by-step explanation:
radius of large sphere is R,
then volume is (4/3)*pie*R³
and
the radius of small sphere is r,
then volume is (4/3)*pie*r³
condition is,
volume of larger sphere is twice of the volume of smaller sphere.
then, (4/3)*pie*R³=2*(4/3)*pie*r³;
R³= 2r³
R=(2^⅓)*r

A T-shirt printing machine takes 80 minutes to print 1120 shirts. Consider the number of shirts printed per minute. Find the constant of proportionality in this situation. b. Write an equation to represent the relationship. How many shirts are printed in 30 minutes?
Answers
Answer:
Every minute there are 14 shirts made so there would be 420 shirts made in 30 minutes. Y=14x
Step-by-step explanation:
Divide 1120 by 80 to get 14 then you multiply 14 by 30 to get 420
Then to get an equation you write the number of shirts made per minute and then plug in how many minutes you want.

Answers
Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
Answer:
x = 20
Step-by-step explanation:
The 2 angles are vertical and congruent, thus
10x - 27 = 8x + 13 ( subtract 8x from both sides )
2x - 27 = 13 ( add 27 to both sides )
2x = 40 ( divide both sides by 2 )
x = 20

Answers
Answer: 1577.14
Step-by-step explanation:
From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.
To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:
= 2,417,760,000 / 1,533,000
= 1577.14 times

You are standing 500 meters from a SpaceXᵗᵐ Rocket that is preparing to take off. The angle of elevation to the top of the rocket is 8o. Find the height of the rocket. Round your answer to the nearest tenth The height of the rocket is meters
Answers
Answer:
70.3mStep-by-step explanation:
The set up will be a right angled tringle with angle of elevation of 8°.
The distance you are standing from the rocket (adjacent) = 500m
The height of the rocket (opposite) = x
Using the SOH CAH TOA trig identity;
According to TOA
tan(theta) = opp/adj
tan 8 = x/500
x = 500tan8
x = 500(0.1405)
x = 70.27
x = 70.3m (to the nearest tenth)
Hence the height of the rocket in meters is 70.3m

The school that Jeremy goes to is selling tickets to a play. On the first day of ticket sales the school sold 8 senior citizen tickets and 9 child tickets for a total of $188. The school took in $70 on the second day by selling 1 senior citizen ticket and 5 child tickets. What is the price of one senior citizen ticket and one child ticket
Answers
Answer:
x=$10
y=$12
Step-by-step explanation:
Step one:
given
let senior tickets be x
and child be y
8x+9y=188----1
also on the second day
x+5y=70-------2
the system of equation is
8x+9y=188-----1
x+5y=70---------2
x=70-5y, put this in 1
8(70-5y)+9y=188
560-40y+9y=188
-31y=-372
divide by -31
y=-372/-31
y=$12
put y= 12 in x+5y=70---------2
x+5(12)=70---------2
x+60=70
x=$10
