Answer:
8 [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Find the LCD of the two fractions, which is six
3[tex]\frac{1}{2}[/tex] = 3 [tex]\frac{3}{6}[/tex]
---------------------------------------------------------------------------------------------------------------
5[tex]\frac{1}{6}[/tex] + 3 [tex]\frac{3}{6}[/tex] = 8[tex]\frac{4}{6}[/tex]
The next step is to reduce:

Answer:
x=8
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
16 = 1/2 (4) x
16 =2x
Divide each side by 2
16/2 = 2x/2
8 =x
The height is 8 units
factorise completely 15p^2 + 24pt
Answer:
3p(5p + 8t)
Step-by-step explanation:
15p^2 + 24pt
3(5p^2 + 8pt)
3p(5p + 8t)
The completely factored form of 15p^2 + 24pt is 3p(5p + 8t).
How to determine the factored formTo factorize the expression 15p^2 + 24pt using superscripts, we can follow the same steps as before.
First, let's find the GCF of the coefficients 15 and 24, which is 3:
GCF(15, 24) = 3
Next, we'll look for the GCF of the variables p^2 and pt, which is p:
GCF(p^2, pt) = p
Now, we can factor out the GCF from each term:
15p^2 + 24pt = 3p(5p + 8t)
Therefore, the completely factored form of 15p^2 + 24pt is 3p(5p + 8t).

[tex]P(New\ House) = \frac{1}{6}[/tex]
Step-by-step explanation:
Given
See attachment
Required
[tex]P(New\ House)[/tex]
This is calculated as:
[tex]P(New\ House) = \frac{New\ House}{Total}[/tex]
From the attachment, we have:
[tex]New\ House = 60^o[/tex]
[tex]{Total}= 360^o[/tex] --- total angle in a pie chart
Note that the measurements must be converted to degrees (if not already in degrees).
So, we have:
[tex]P(New\ House) = \frac{60}{360}[/tex]
Simplify
[tex]P(New\ House) = \frac{1}{6}[/tex]

The histogram shows the number of laps completed by swimmers on a team during practice.
A. which interval contains the most values?
B. How many swimmers are on the team?
C. What percent of the swimmers swam more than 14 laps? Round o the nearest tenth of a percent.
Explain.
Answer:
A) 10-14
B) 45
C) 6.7%
Step-by-step explanation:
A) The interval that contain the most values can be gotten by looking at the histogram and selecting the interval with the highest frequency. Hence the interval 10-14 contains the most values because it has a frequency of 20.
B)The total number of swimmers is gotten by summing all the frequency of each individual lap. Hence:
Total swimmers on team = 10 + 12 + 20 + 0 + 3 = 45 swimmers
C) The percentage of swimmers who swam more than 14 laps = (number of swimmers that swam more than 14 laps/total swimmers) * 100%
The percentage of swimmers who swam more than 14 laps = [(0 + 3)/45] * 100% = (3/45) * 100% = 6.7%

what is the range of the function graphed below?
i honestly have no idea please help
Answer:
C
Step-by-step explanation:
The range of a graph is how far the graph goes up and down. The lower boundary is easy, as we can see that the left side of the line goes down forever, so it is negative infinity. Looking at the top of the graph, we can see that the graph never goes past y=2. So the answer is:
-∞<y<2

Answer:
-3
Step-by-step explanation:
Pick two points on the line
(-1,0) and (0,-3)
You can find the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( -3-0)/(0- -1)
= (-3-0)/(0+1)
= -3/1
= -3

Answer and Step-by-step explanation:
The last answer choice is correct.
Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x
The process being used in the last answer choice is called Cross multiplication, and is used to find the unknown value in fractions.
