Answers
Answer:
B, X = 2
Step-by-step explanation:
Since 55 divided by 5 parts is each x + 9, that means 5(x + 9) = 55. Distributing, we get 5x + 45 = 55, and subtracting 45 from each side gets us 5x = 10. Dividing each side by 5 gets us x = 2.
Step-by-step explanation:
(x+9) * 5 = 55
9 * 5 = 45
55-45 = 5
x = 1

b. 5 is 50% of what number?
c. 10% of what number is 300?
d. 5% of what number is 72?
e. 20 is 80% of what number?
Answers
B. 10
C. 3,000
D. 1,440
E. 16
The required solution of the given percentages is as follows,
a.12 is 150% of 8.
b. 5 is 50% of 10.
c. 300 is 10% of 3000.
d.72 is 5% of 144.
e. 20 is 80% of 400.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
here,
a. To find the number that 12 is 150% of, we can set up a proportion:
12 = 150% of x
We can convert 150% to a decimal by dividing by 100:
12 = 1.5x
Dividing both sides by 1.5 gives:
x = 8
Therefore, 12 is 150% of 8.
Similarly,
b. 5 is 50% of 10.
c. 300 is 10% of 3000.
d.72 is 5% of 144.
e. 20 is 80% of 400.

A curious patterns occurs in a group of people who all shake hands with one another. It turns out that you can predict the number of handshakes that will occur if you know the number of people. If we are in a room of 5 people, we can determine the number of handshakes by this line of reasoning: The first person will shake 4 hands (she won’t shake her own). The second person will shake 3 hands (he won’t shake his own of the hand of the first person, they already shook). The third person will shake 2 hands (same reasoning). The fourth person will shake 1 hand (that of the fifth person). The fifth person will shake 0 hands. So there will be a total of 1+2+3+4=10 handshakes
Answers
Missing part of the question
Determine the number of handshakes, i, that will occur for each number of people, n, in a particular room. (people)
Answer:
[tex]S_n = \frac{n}{2}(n - 1)[/tex]
Step-by-step explanation:
Given
For 5 people
[tex]\begin{array}{cc}{People} & {Handshakes} & {5} & {4} & {4} & {3} & {3} & {2} & {2} & {1} & {1} & {0} &{Total} & {10} \ \end{array}[/tex]
Using the given instance of 5 people, the number of handshakes can be represented as:
[tex](n - 1) + (n - 2) + (n - 3) + ........ + 3 + 2 + 1 + 0[/tex]
The above sequence is an arithmetic sequence and the total number of handshakes is the sum of n terms of the sequence.
[tex]S_n = \frac{n}{2}{(T_1 + T_n})[/tex]
Where
[tex]T_1 = n - 1[/tex] --- The first term
[tex]T_n = 0[/tex] --- The last term
So:
[tex]S_n = \frac{n}{2}(n - 1 + 0)[/tex]
[tex]S_n = \frac{n}{2}(n - 1)[/tex]

What is a resistor?A resistor is a two-terminal passive electrical component that uses electrical resistance as a circuit element.
The voltage of a circuit decreases when a resistor is present in the circuit, therefore, the options with the light bulbs are not the correct options. Since a 9V battery has more voltage than a 1.5V battery.
Therefore, the correct option is A.

A summer camp counselor wants to
calculate a length, x, in feet, across a pond
as represented in the sketch. Segments AC
and DE intersect at B, and AEB and CDB
have the same measure. What is the distance
across the pond? Round to the nearest
hundredth.
Answers
Answer: 1600
Explanation: If angles E and D are the same with the lines intersecting at B, then that means that A and C are also the same, as the opposite angles formed at point B are also the same, so you have two similar triangles.
Similar triangles have proportional lengths. So we know length CD is 800 ft and its similar leg on the other side (AE) is unknown.
So we need to find two known lengths, one on the large and one on the small, that are similar.
BE is 1400 ft and BD is 700 ft. Those are you two known similar legs. So now we can use them in a proportion to find AE.
We will do the line ending at B over the line that doesn't include B.
Large triangle:
x
1400
Small triangle:
800
700
Set them up in a proportion:
x
1400
=
800
700
Solve for x:
⇒7x=11200
⇒x=1600 ft

Write an equation that relates the number of tennis balls (y), with the number of cans (x). (Do not put spaces between numbers, variables, and operations)
Answers
Answer:
y = 3x
Step-by-step explanation:
Since, line given in the graph passes through origin (0, 0), relation between the number of tennis balls (y) and the number of cans (x) will be proportional.
y ∝ x
y = kx
Here 'k' = proportionality constant
Since the given line is passing through (1, 3),
3 = k(1)
k = 3
Therefore, equation of the line will be,
y = 3x
