Isaac finished eight of the ten homework problems. Phil has finished of the homework. How many more problems did Isaac finish?
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.
The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?
Answer:
As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.
Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.
Subtract the 2 hours from 10am:
= 10 - 2
= 8am
Subtract the 15 minutes from 45:
= 45 - 15
= 30
Put that together:
= 8:30 am
They left their house at 8:30 am using this scenario.

if r = 1 and 0 = 7pi /6 what is the approximate arc length
0 = theta
A.)1.75
B.)5.498
C.)21.991
D.)7.330
Answer:
[tex]l = 3.66[/tex]
Step-by-step explanation:
Given
[tex]r =1[/tex]
[tex]\theta = \frac{7\pi}{6}[/tex]
Required
The arc length (l)
This is calculated as:
[tex]l= r\theta[/tex]
So, we have:
[tex]l = 1 * \frac{7\pi}{6}[/tex]
[tex]l = \frac{7\pi}{6}[/tex]
So, we have:
[tex]l = \frac{7*3.14}{6}[/tex]
[tex]l = 3.66[/tex]

What is the distance to the nearest tenth of a unit between point H ( -4,6 ) and point I ( 2,-3 )
Answer:
10.81 units
Step-by-step explanation:
Given data
point H ( -4,6 ) and point I ( 2,-3 )
x1= -4
y1=6
x2= 2
y2=-3
The formula for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(-3-6)²)
d= √(2+4)²+(-9)²)
d= √(6)²+(-9)²)
d= √36+81
d=√117
d= 10.81 units
Hence the distance between the points is 10.81 units

Alice is searching online for tickets to a knicks game. Two weeks ago, the cost was $30. Now the cost is $39. What is the percent increase
Given:
Two weeks ago, the cost of tickets = $30
Now, the cost of tickets = $39
To find:
The percent increase.
Solution:
We have,
Initial value = $30
New value = $39
Formula for percentage increase is:
[tex]\%\text{increase}=\dfrac{\text{New value - Initial value}}{\text{Initial value}}\times 100[/tex]
Using this formula, we get
[tex]\%\text{increase}=\dfrac{39-30}{30}\times 100[/tex]
[tex]\%\text{increase}=\dfrac{9}{3}\times 10[/tex]
[tex]\%\text{increase}=3\times 10[/tex]
[tex]\%\text{increase}=30[/tex]
Therefore, the percent increase in the cost of tickets is 30%.

Jayna used the distributive property to simplify the expression 4(a + 2) and got(4a + 2). Do you agree with Jayna?
Answer:
No
Step-by-step explanation:
I would not agree with Jayna because using the distributive property, you can get:
4(a + 2) = 4(a) + 4(2) = 4a + 8
Jayna did not get the right answer because she did not distribute the 4 to the 2 in a + 2 and she only multiplied a by 4.

What is the surface area of this composite solid?
Use 11.3 meters for the slant height of the triangular prism.
Enter your answer in the box.
__m²
Composite made up of a rectangular prism surmounted by a triangular prism. The rectangular prism has dimensions of 16 meters wide by 20 meters long by 12 meters high. The triangular prism has dimensions of 16 meters wide by 20 meters long with a triangular altitude of 8 meters high.
Answer:
1764 m²Step-by-step explanation:
Refer to attached picture.
All given dimensions are given on the picture (not to scale).
Since altitude of the triangle and slant height is given, we can find the base of the triangle using Pythagorean:
[tex]b/2 = \sqrt{11.3^2-8^2} = \sqrt{64} = 8m, \\b = 16 m[/tex]It has 9 faces and the total surface area is:
S = 16*20 + 2(20*12) + 2(20*11.3) + 2(16*12) + 2(1/2*8*16) = 1764 m²Daryl can jump 2 1/2 yards. Sarah can jump 8 feet and Michelle can jump 72 inches.Which statement is true?
