Answer:
11/24
Step-by-step explanation:
Just add 1/3 and 1/8 to get the answer. To add or subtract any pair of fractions they must have the same denominator. To change them, find the least common multiple of the two denominators (3 and 8). The least common multiple of 3 and 8 is 24. Now multiply the denominator by a number that’ll make it into the least common multiple. The 3 in 1/3 should be multiplied by 8 to make it into 24. The 8 in 1/8 should be multiplied by 3 to make into 24. The number that you use to multiply each denominator should also be used to multiply the numerator of that fraction. 1/3 for example, becomes 8/24. 1/8 becomes 3/24. Finally add the numerators of both numbers and keep the same denominator which equals 11/24.
If ∠4 ≅ ∠5 then ∠5 ≅ ∠4.

Find the percent of increase
6. from 44 to 66 7. from 6 to 6.5
Find the percent decrease. Where necessary round to the nearest tenth of a percent
8. from 56 to 36 9. from 72 to 18
Answer:
6. 33% increase
Step-by-step explanation:
Equation of increase/decrease: (Final value-initial value)÷(Initial Value)
6. (66-44)÷(66)=0.33
-Multiply by 100 to get 33% increase
7. (6.5-6)÷(6)=0.083
-Round and multiply by 100 to get 8.0% increase
8. (56-36)÷(56)=0.357
Round and multiply by 100 to get 36% decrease
9. (72-18)÷72=0.75
Multiply by 100 to get 75% decrease
Answer:
from 44 to 66 7 from 6 to 6.5
1415.9090909091%

Fill in the gaps to factorise this expression
12+2x= 2(_+_)
The complete expression will be written as 12+2x = 2( 6 + x).
What does a mathematical expression mean?
A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.
This mathematical operation may be addition, subtraction, multiplication, or division.
Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,
2( 6 + x)
= 12 + 2x
12+2x = 2( 6 + x)
Therefore, the complete expression will be written as 12+2x = 2( 6 + x).

What is the first step to solving the following equation?5x –11 = 42
Answer:
add the 11 to both sides to cancel it out.
Step-by-step explanation:
so basically
5x - 11 + 11 = 42 +11
5x = 53
The required first step of solving the given expression is to add 11 on both sides.
Given that,
The first step for the solution of the given expression 5x - 11 = 42 is to be determined.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
5x - 11 = 42
Add 11 on both sides to reduce the equation as
5x = 53
Thus, the required first step of solving the given expression is to add 11 on both sides.

On a test Jenna gets 85% of the questions correct, Linda get 32 out of 40 questions correct, Karl gets 7/8 correct, and julie gets 0.83 of the questions correct. List the students in order from lowest to higest.
Answer:
Linda, Julie, Jenna, Karl
Step-by-step explanation:
Here, we want to list the students in order from lowest to highest
The key here is to have the scores in the same form, let us say decimals for ease of comparison
Jenna: 85% = 85/100 = 0.85
Linda’s= 32/40 = 80% = 0.8
Karl = 7/8 = 0.875
Julie = 0.83
So from lowest to highest, we have;
Linda, Julie, Jenna, Karl
Lucille has an aquarium with 9 gallons of water which weighs 85 pounds. The stand holding the aquarium can hold no more than 112 pounds. She wants to add 2.5-pound rocks, r, her tank. Complete the inequality to show how many rocks she can add. R≤
Answer:
[tex]r\leq 10.8[/tex]
OR
[tex]r\leq 10[/tex]
Step-by-step explanation:
Given that:
Amount of water in the aquarium = 9 gallons
Weight of water in the aquarium = 85 pounds
Total weight that aquarium can hold = 112 pounds
Weight of each rock = 2.5 pounds
To find:
The inequality to find the number of rocks, [tex]r[/tex] that can put in her tank.
Solution:
First of all, let us find more weight that the aquarium can hold after putting the water in the aquarium.
Additional weight that can be put in the aquarium = Total weight - Weight of water = 112 - 85 = 27 pounds
This 27 pounds can be of rocks.
Let the number of rocks that can be put in the aquarium = [tex]r[/tex]
Total weight of [tex]r[/tex] number of rocks = Weight of one rock multiplied by [tex]r[/tex]=2.5[tex]r[/tex]
Now, this weight of rocks must be lesser than or equal to 27 pounds.
Therefore, the in equality is:
[tex]2.5r\leq =27\\\Rightarrow r \leq 10.8\\OR\\\Rightarrow r \leq 10[/tex]
The weights of dogs at a kennel are Normally distributed with a mean of 18 pounds and a standard deviation of 3.5 pounds.In which percentile is a dog who weighs 25 pounds?
Answer:
P(x=25)=P(z=2)=0.9972 or 99.72%
Step-by-step explanation:
Mean = 18 pounds
Standard Deviation = 3.5 pounds
x= 25
We need to find P(x=25)
First, we need to find z-score using formula: [tex]z-score=\frac{x-\mu}{\sigma}[/tex]
Finding z-score when x=25
[tex]z-score=\frac{x-\mu}{\sigma}\\z-score=\frac{25-18}{3.5}\\z-score=2[/tex]
So, we need to find P(z=2)=P(x=25)
Looking at z-score table we can find P(z=2)
P(z=2)=0.9972 or 99.72%
So, P(z=2)=0.9972 or 99.72%
Answer:
97.5th percentile

The formula for the volume, V, of a shape is given by V = Ah. A is the area and h is the height.
(a) Find the volume of the shape if A = 40 and h = 8
(b) Find the area of the shape if V= 800 and h = 20
Answer:
Step-by-step explanation:
a) V= A*h V=40*8=320
b) V=800 and h=20
A=V/h=800/20=40
Answer:
see explanation
Step-by-step explanation:
Given the formula
V = Ah
with A = 40 and h = 8 , then
V = 40 × 8 = 320 units³
(b)
Given V = 800 and h = 20, then
800 = 20A ( divide both sides by 20 )
A = 40 units²
