Answer:
B
Step-by-step explanation:
1) use a proportion to find how many students chose pizza
30 : 100 = x : 80
x = (80 x 30)/100 = 24
2) use a proportion to find how many students chose salad
10 : 100 = x : 80
x = (80 x 10)/100 = 8
3) solve the question
24 - 8 = 16
Answer:
12 STUDENTS CHOSE HAMBURGERS
24 STUDENTS CHOSE PIZZA
16 STUDENTS CHOSE SANDWHICHES
20 STUDENTS CHOSE HOT DOGS
8 STUDENTS CHOSE SALAD
24 = PIZZA
8 = SALAD
8 - 24 = 16 SO B

Hannah just put a 36-foot long
fence around her rectangular
garden. What is the length of the
garden if it is 12 feet wide?
Answer:
perimeter=sum of all sides
p=2(L+W)
36=2(L+12)
36-24=2L
12=2L
L=6
A rectangle is a 2-D shape with 4 angles. The length of the garden if it is 12 feet wide is 3 feet
How to calculate the perimeter of a rectangle?A rectangle is a 2-D shape with 4 angles. The formula for calculating the perimeter of a rectangle is expressed as:
P = 2(length + width)
Given
Perimeter = 30 feet
width = 12 ft
Substitute
30 = 2(l + 12)
15 = l + 12
l = 3 feet
Hence the length of thegarden if it is 12 feet wide is 3 feet

Pythagorean theorem: find the perimeter
What is the perimeter?
Answer:
5
Step-by-step explanation:
Lets recall what the pythagroens theorm is:
A^2+B^2=C^2. A and B are the side lengths(adjacent and opposite), while C is the longest sloped length(hyotenouse).
Lets plug in our values for each, and solve for the missing one:
12^3+b^2=13^2
Square each value(except for unknown):
144+b^2=169
Now get b alone(subtract 144 from both sides):
b^2=25
Now root both sides(removes the ^2):
b=5
This is your answer!
Hope this helps! :)
The product of two positive numbers is 84. The larger number is 2 more than twice the smaller number. What is the larger number?
Answer:
44. (Sorry if im incorrect. I don't clearly understand the question)
Step-by-step explanation:
Answer:
14 or -12
Step-by-step explanation:
Start by writing an equation for this.
84 = x * (2x + 2)
This expression works because 84 is the product of the number (x) and twice the number plus 2.
Using the equation, solve for x.
84 = x * (2x + 2)
First, simplify.
84 = 2x^2 + 2x
Subtract 2x^2 + 2x to make the equation equal to 0.
84 - 2x^2 + 2x = 0
Factor:
−2(x − 6)(x + 7) = 0
Set factors equal to 0.
x − 6 = 0 or x + 7 = 0
x = 6 or x = -7
x represents the smaller number. The larger number is 2x + 2.
So double x and add 2.
2(6) = 12 and 12 + 2 = 14 so that's one of the options
2(-7) = -14 and -14 + 2 = -12 so that's the other.
Check:
14 * 6 = 84
-12 * -7 = 84

MUST SHOW WORK!!!
Answer:
The variable c=9 is the answer the varibles
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
c = −15.8571428571
Step-by-step explanation:
-42 = 5(2c + 9) - 3(c + 8)
-42 = 10c + 45 - 3c + 24
-42 = 10c - 3c + 45 + 24
-42 = 7c + 69
-7c -7c

-7c - 42 = 69

Write an explicit formula for a_na n , the n^{\text{th}}n th term of the sequence 5, -25, 125,
The explicit formula for the given geometric sequence is [tex]a_n=5\times(-5)^{n-1}[/tex].
The given sequence is 5, -25, 125,.......
Here, the common ratio is -25/5 = -5 and 125/(-25) = -5.
We know that, the explicit formula for an geometric sequence is [tex]a_n=ar^{n-1}[/tex].
Where, a = first term of the sequence, r= common ratio and n = number of terms.
Substitute, a=5 and r=-5 in [tex]a_n=ar^{n-1}[/tex], we get
[tex]a_n=5\times(-5)^{n-1}[/tex]
Therefore, the explicit formula for the given geometric sequence is [tex]a_n=5\times(-5)^{n-1}[/tex].

What is the INTERQUARTILE RANGE for the data: , 3, 4, 4, 6, 7, 7, 9,
Answer:
The interquartile range for this data set is 3.
Step-by-step explanation:
We are given the data set : 3, 4, 4, 6, 7, 7, 9
In order to find the interquartile range, we can create a box plot for this data set. Each box plot contains a minimum, lower quartile, median, higher quartile, and maximum. Let's find the minimum and maximum before the others as it is the easiest one to identify. The minimum here would be 3 since that's the lowest number here in this data set. The maximum here would be 9 since that's the highest number here in this data set. Before we find the lower and higher quartile, let's find the median first since that way, we don't get mixed up between so many numbers. To find the median, you need to find the value that lies at the middle point throughout the data set. Since there are 7 values in this data set which is a odd number, all we need to do is cross out the first and last value as each set goes by.
3, 4, 4, 6, 7, 7, 9
4, 4, 6, 7, 7
4, 6, 7
6
The work above shows each set of the first and last value getting shorter and shorter, so the median of the data set would be 6. The values, 3, 4, and 9 have already been used. Now that we know the median, the second lowest number here is 4 (lower quartile) and the second highest number here is 7 (higher quartile). In order to find the interquartile range, you need to find the difference between the lower quartile and higher quartile, which means to subtract.
7 (higher quartile) and 4 (lower quartile) = 3 (interquartile range)
Therefore, the interquartile range for this data set is 3.

Answer:
592
Step-by-step explanation:
Surface area of a rectangular prism = 2lw + 2lh + 2wh
where w = width, h = height and l = length
These are the given dimensions...
length = 12 cm
width = 8 cm
height = 10 cm
To find the surface area we plug in the given values into the formula
[tex]SA=2(12)(8)+2(12)(10)+2(10)(8)\\12*8=96\\96*2=192\\12*10=120\\120*2=240\\10*8=80\\80*2=160\\160+240+192=592[/tex]
Hence, the surface area of the rectangular prism is 592
