Step-by-step explanation:
change = 20 - (3.99(3) + 2.99(1) + 3.09(1) + 0.78)
= 20 - (11.97 + 2.99 + 3.09 + 0.78)

A and B are supplementary angles. If m A=(x-18)° and mB =(x-20),
find the measure of B
Answers
Answer:
89 degrees
Step-by-step explanation:
supplementary angles add up to 180 degrees, so we can add up A and B and make it equal to 180.
(x-18)+(x-20)=180
2x-38=180
2x=218
x=109
then, we plug in 109 for x in the mB equation.
mB=x-20
mB=109-20
mB=89 degrees
therefore, the measure of B is 89 degrees.
Answer:
B = 89
Step-by-step explanation:
Supplementary angles: A + B = 180
Simplify: x-18 +x -20 = 180
2x-38 = 180
2x = 218
x= 109
B = x-20
B = 89

Find the value of x in each of the following
a) 5x/2+ 1 = 11
b) 2x/7 – 3 = 2
Answers
Answer:
A) x=4
B) x=35/2
Step-by-step explanation:
calculate the product
A) 5x/2+1=11
multiply both sides of the equation by 2
5x+2=22
move the constant to the right hand side and change its sign
5x+22-2
now subtract the numbers
5x=20
now didvide both sides
5x=20
x=4
B)
calculate the product
2x/7-3=2
multiply both sides of the equation by 7
2x-21=14
move the constant to the right hand side and change its sign
2x=14+21
add the numbers
2x=35
now divide both sides of the equation by 2
x=35/2
On January 3rd, the Earth is 147,500,000 kilometers away from the Sun. On July 4th, the Earth is 152,500,000 kilometers away from the Sun. The Sun has a radius of about 865,000 kilometers.
Could the Earth's orbit be a circle with some point in the Sun as its center? Explain your reasoning.
Answers
Answer:
No
Step-by-step explanation:
It could not because in order for it to be a circle the number of kilometers would have to be constant, however in earth's orbit it is not constant, therefore it is an oval, not a circle.

write 843 in scientific notation.
Answers
a x 10b
Follow the steps below to see how 843 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 843New Number: 8.43Step 2
Now, to find b, count how many places to the right of the decimal.
New Number:8.43Decimal Count:12
There are 2 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.43
b = 2
Now the whole thing:
8.43 x 102
Step 4
Check your work:
102 = 100 x 8.43 = 843

Step-by-step explanation:
C is the correct answer. I see that you put a mark on that choice so you are right if you thought that. I hope this helps!
Answer:
C
Step-by-step explanation:
The 2 angles are same- side interior angles and are supplementary, thus
3x - 5 + 2x - 15 = 180, that is
5x - 20 = 180 ( add 20 to both sides )
5x = 200 ( divide both sides by 5 )
x = 40
Thus
3x - 5 = 3(40) - 5 = 120 - 5 = 115°
2x - 15 = 2(40) - 15 = 80 - 15 = 65°

The cost for each person attending is $3.50 for skate rental and $5.00 for food. Jezebel cannot spend more than $300. Which inequality could be used to find the greatest number of people, p, that can attend?
Answers
Answer:
The inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.
Step-by-step explanation:
From the information provided, you can write an inequality where total cost for people attending at the party should be less than or equal to $300:
3.50p+5.00p≤300
8.50p≤300
Now, you can solve for p:
p≤300/8.50
p≤35
According to this, the answer is that the inequality that could be used is 8.50p≤300 and the greatest number of people that can attend is 35.

The volume of a rectangular pool is the product of the pool's area and depth. Suppose a pool that is 12 feet deep has

square feet.
The area of the pool is the product of the pool's length and width. Suppose the pool's length is 24 ft. What is the
pool's width?
The pool's width is
feet
Answers
Answer:
The area of the pool is [tex]864\ ft^2[/tex]
The pool's width is 36 ft
Step-by-step explanation:
Volume and Area
The volume of a rectangular pool is the product of the pool's area and depth. We are given the pool's depth d=12 feet and the pool's volume V=10368 [tex]ft^3[/tex]
Since:
[tex]V= d*A[/tex]
Solving for A:
[tex]\displaystyle A=\frac{V}{d}=\frac{10368}{12}=864\ ft^2[/tex]
The area of the pool is [tex]864\ ft^2[/tex]
Now we calculate the pool's width, knowing the area is the product of the pool's length and width. Knowing the length is L=24 ft:
[tex]A=L*W[/tex]
Solve for W:
[tex]\displaystyle W=\frac{A}{L}=\frac{864}{24}=36[/tex]
The pool's width is 36 ft

Ojos del Salado is the highest mountain in Chile, with a peak at about 6900 meters above sea level. The Atacama Trench, just off the coast of Peru and Chile, is about 8100 meters below sea level (at its lowest point).
a. What is the difference in elevations between Mount Ojos del Salado and the Atacama Trench?
b. Is the elevation halfway between the peak of Mount Ojos del Salado and the Atacama Trench above sea level or below sea level?
Explain without calculating the exact value. c. What elevation is halfway between the peak of Mount Ojos del Salado and the Atacama Trench?
Answers
A) add the two elevations together:
6900 + 8100 = 15,000 meters.
B) Divide the total distance by 2:
15,000 / 2 = 7,500 meters.
Because the distance to the halfway point is larger than the elevation of Ojos del Salado, the elevation would be below seal level.
C Add the halfway point from part B to the lowest elevation:
-8100 + 7500 = -600 meters
