Frank finds 9 coins on the floor of his car, and 3 of them are quarters. If he finds 15 more coins on the ground, at the same ratio as the coins found in the car, how many more coins will most likely be quarters?
Answer: 5 coins
Step-by-step explanation:
Frank found 9 coins on the floor of his car, and 3 of them were quarters. This means that 3 out of the 9 coins, or \(\frac{3}{9}\), were quarters.
Simplifying this fraction, we get \(\frac{1}{3}\) of the coins found in the car were quarters.
If Frank finds 15 more coins on the ground at the same ratio, then \(\bold{\frac{1}{3}}\) of these coins will also be quarters. To find out how many quarters he will most likely find, we need to find \(\bold{\frac{1}{3}}\) of 15:
\(\large \frac{1}{3} \times 15 = 5\)
Therefore, Frank will most likely find 5 more quarters on the ground, assuming he finds coins at the same ratio as he did in his car.

Bryan and his son, and Elton and his son all went fishing. Bryan caught as many fish as his son and Elton caught three times as many fish as his son. All together, they caught 25 fish. How many fish did Bryan catch?
Answer:
The answer is explained below
Step-by-step explanation:
This is a word problem, therefore to solve it the statement have to be writing in form of an equation and then solved.
Let the number of fishes caught by Bryan's son be x fishes. Since Bryan caught as many fish as his son, Bryan caught x fishes
Let the number of fishes caught by Elton's son be y fishes. Since Elton caught three times as many fish as his son, Bryan caught 3y fishes
All together, they caught 25 fish
Therefore it can be represented by the equation:
x + x + y + 3y = 25
2x + 4y = 25
2x = 25 - 4y
x = (25 - 4y)/2
The number of fish caught by Bryan is half of the difference between the total fish caught and four times the number of fish caught by Elton son
What does it mean to combine like terms?
Answer:
Combining like terms mean to solve those terms whose have same bases
Answer:
like terms would be like 15 and 24 or 5x and 3x.
as long as they don't have a different variable or on a different side of the = sign they are considered like terms.
3 and 5x are not like terms

What is the value represented by the letter A on the box plot of data?
5, 20, 40, 50, 50, 85
Answer:
The value represented by the letter A on the box plot of data is 5
Step-by-step explanation:
The set of data is
{5, 20, 40, 50, 50, 85}
In the given box plot,
A = Minimum value
B = First quartile
C = Median
D = Third quartile
E = Maximum value
Since the minimum value of the set is 5, therefore the value represented by the letter A on the box plot of data is 5.

A computer is programmed to generate a sequence of three digits, where each digit is either 0 or 1, and each of these is
equally likely to occur. Construct a sample space that shows all possible three-digit sequences of 0s and 1s and then find
the probability that a sequence will contain exactly one 0.
A. 000, 001, 010, 011, 100, 101, 110, 111; the probability is 7/8
B. 001, 011, 101, 111; the probability is 2/8
C. 000, 010, 011, 101, 111, the probability is 2/8
D. 000, 001, 010, 011, 100, 101, 110, 111, the probability is 3/8
Answer:
A
Step-by-step explanation:
on edge2021
The probability that a sequence will contain exactly one zero is true in options {B}, {C} and {D}.
We can write the formula for probability as -
P{Event} = (no. of favorable outcomes)/(Total no. of favorable outcomes)
For the sequence {A} -
000, 001, 010, 011, 100, 101, 110, 111
P{one zero} ≠ 7/8
For the sequence {B} -
001, 011, 101, 111
P{one zero} = 7/8
For the sequence {C} -
000, 010, 011, 101, 111
P{one zero} = 2/8
For the sequence {C} -
000, 001, 010, 011, 100, 101, 110, 111
P{one zero} = 3/8

The answer is 8 so its a direct proportion
I think...
The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

show that the (5,5),(5,0),and (0,0) are the vertices of an isosceles triangle.
An isosceles triangle has 2 sides that are equal.
I plotted these points. See attached screenshot.
The first side's distance is 5. You can just count those units along the x axis. (0,0) and (5,0) share the same y coordinate, so the difference in x coordinates is 5-0 = 5.
The next sides's distance is also 5. You can count that distance on the coordinate plane. (5,5) and (5,0) share the same x coordinate, so the difference in y coordinates is 5-0 = 5.
These two sides make a right triangle and are equal length. This is an isosceles right triangle.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.

Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A

what is the product of -16 x -5 x -11?
please give an answer and explanation
Answer: -880
Step-by-step explanation:
This is based on the fact that 2 negatives equals a positive and 1 negative + 1 positive equals a negative.
First, you would multiply two of the three numbers, I did -5 * -11 as it seemed like the easiest. Two negatives makes a Positive so that's: -5 * -11 = 55. Now you can do 55 * -16. One Negative and One Positive makes a Negative so the answer is -880. You can use column method or whatever method you use to multiply two digit numbers but I would always think of it as two different equations.
Hope this is an okay explanation!

If a value of 80.4° is added to the data, how does the range change?
The range decreases to 46°.
The range stays 48°.
The range stays 49°.
The range increases to 50°.
Answer:
The Range Stays 48°.
Step-by-step explanation:\
Since the value 80.4° is not the highest and not the lowest value on the list, it does not change the range.
Hope this helps!
Answer: B. The range stays 48
Step-by-step explanation:
The largest answer is 105 and the smallest answer is 57. The range is the range of numbers from smallest to largest so to find the range you subtract the largest and the smallest
Range = 105 - 57
Range = 48
The range will not change because if you put 80.4 in there, it's not the largest or smallest so it does not affect the range.
So answer is B. The range stays 48
0.2 ( 10 - 5c ) = 5c - 16
Answer: c = 3
Step-by-step explanation: Distribute 0.2 to (10-5c)
2-1c=5c-16
Then subtract 2 on both sides and subtract the 5c.
-1c=5c-18
-6c=-18
Then divide -6 to -18
-18/-6 = 3
