Answer:
-2
Step-by-step explanation:
If Issac has finished 8/10 problems in the homework, and Phil has completed all of it, it can be concluded that Phil completed 10/10. 10/10 would equal a whole, or in this case, the entire homework. If Issac completed 8 problems, and Phil completed 10, subtract both values to find that Issac completed -2 more problems than Phil.
*correct me if I'm wrong, or If I didn't fully understand your question, because I am a little confused with how much homework Phil has finished.

Write an equation for the sine wave. What is the amplitude and period?
Answer:
Amplitude is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat. Using this equation: Amplitude =APeriod =2πBHorizontal shift to the left =CVertical shift =D.
why is this true 7a+4-2a=7a+ -2a+4
Answer:
Step-by-step explanation:
Notice that both sides involve 7a - 2a, and both involve 4. By the associative property the order in which the addends appear is immaterial; the left side therefore equals the right side.
Answer:
7a + 4 - 2a = 7a - 2a + 4
5a + 4 = 5a + 4
Step-by-step explanation:
7a + 4 - 2a = 7a - 2a + 4
7a + 4 - 2a
Rearrange the terms.
7a - 2a + 4
Combine like terms.
5a + 4
The left side simplifies to 5a + 4.
7a - 2a + 4
5a + 4
The right side also simplifies to 5a + 4.
Find the values of x and y
Answer:
x = 54, y = 63
Step-by-step explanation:
117° and the left base angle are adjacent and sum to 180°
base + 117° = 180° ( subtract 117° from both sides )
base = 63°
Since the triangle is isosceles ( congruent legs ) then the 2 base angles are congruent , so y = 63
and x = 180 - (63 + 63) ← sum of angles in a triangle
x = 180 - 126 = 54
you spin the spinner shown below once. each sector shown has an equal area. what is P(ladybug)
Answer:
1/5 or 20%
All sectors have an equal area, so that means that all have an equal chance of being landed on. There is only 1 sector containing a ladybug out of all 5 sectors. That means you have a 1 out of 5 chances of landing on the ladybug if you spin once.

Answer:
The equation for the speed of the train is: 162 = 3x
I think the speed of the train is 54 miles per hour
Step-by-step explanation:
We know that:
y = distance in miles
x = speed of train (miles/hour)
t = time traveled from the departing station (hours)
The equation: y = xt is given, we can therefore substitute the give values:
y = xt or tx
162 = 3x (This would be the equation)
Now we can find x by diving 3 on both sides of "="
162/3 = x
54 = x (This would be the speed of train)
Hope this helps!

Round 8.157 to the nearest hundredth.
Answer:
I believe the answer is 8.16 pardon me if it's wrong.
Answer:
8.18
Step-by-step explanation:
First, note that 8.175 has two parts. The integer part to the left of the decimal point and the fractional part to the right of the decimal point:
Integer Part: 8
Fractional Part: 175
To round 8.175 to the nearest hundredth means to round the numbers so you only have two digits in the fractional part.
We use the following rules to round 8.175 to the nearest hundredth:
A) If the last digit in the fractional part of 8.175 is less than 5, then simply remove the last the digit of the fractional part.
B) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is less than 9, then add 1 to the second digit of the fractional part and remove the third digit.
C) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is less than 9, then add 1 to the first digit in fractional part and make the second digit in fractional part 0. Then remove the third digit.
D) If the last digit in the fractional part of 8.175 is 5 or more and the second digit in the fractional part is 9, and the first digit in the fractional part is 9, then add 1 to the integer part and make the fractional part 00.
With 8.175, rule B applies and 8.175 rounded to the nearest hundredth is:

.) A store receives 8 boxes of picture frames to sell. Unfortunately, 3 of the frames are broken and cannot be sold. There are 45 frames left that can be sold. The store manager wants to know how many frames are in each box. ) Write an equation
Answer:
There are 6 boxes
Step-by-step explanation:
We know there are 45 frames and 3 broken ones, so there are 48 frames in total.
We know there are 8 boxes that have the frames.
let x equal the amount of picture frames in a box
8x=48
8x/8 = 48/8

(4pq+3q)² - (4pq - 3q)²
Answer:
48pq².
Step-by-step explanation:
(4pq+3q)² - (4pq - 3q)²
This is the difference of 2 squares so we can use the identity
a^2 - b^2 = (a - b)(a + b):
(4pq+3q)² - (4pq - 3q)²
= (4pq + 3q - (4pq - 3q)(4pq + 3q + (4pq - 3q)
= (4pq + 3q - 4pq + 3q)(4pq + 3q + 4pq - 3q)
= 6q * 8pq
= 48pq².
Answer:
48pq²
Step-by-step explanation:
As we know,
(a + b)² = a² + 2ab + b²
and
(a – b)² = a² – 2ab + b²
So,
(4pq+3q)² - (4pq - 3q)²
= [(4pq)² + 2 X 4pq² X 3q + (3q)²] – [(4pq)² - 2 X 4pq² X 3q + (3q)²]
= (16p²q² + 24pq²+ 9q²) – (16p²q² – 24pq²+ 9q²)
= 16p²q²+ 24pq²+ 9q² – 16p²q²+ 24pq² – 9q²
= 24pq² + 24pq²
= 48pq²
I need help on this
Answer:
1200
Step-by-step explanation:
Step 1 convert pounds to ounces
1 pound = 16 ounces
So to convert pounds to ounces we multiply by 16
1500 * 16 = 24000
So there are 24000 ounces in 1500 pounds
Step 2 Find how many 20 ounce containers he can fill.
To find out how many 20 ounce containers he can fill we divide the total amount of ounces of butter that he has by 20
So answer = 24000/20
24000 / 20 = 1200
Therefore he can fill 1200 20 - ounce containers
