Suppose while at a store, you ask for change for five dollars. You get in return exactly twenty-four coins, all of which are nickels and quarters. How many nickels and quarters did you receive?
Answer: 5 nickels and 19 quarters
Step-by-step explanation:
Let represent the number of nickels and let represent the number of quarters.
From the problem we can write these two equations:
+ = 24; (0.05) + (0.25) = 5.00
Isolate in the first equation: = 24 − .
Substitute 24 − for and solve for :
(24 − )(0.05) + (0.25) = 5.00
24(0.05) − (0.05) + (0.25) = 5.00
1.20 − 0.05 + 0.25 = 5.00
1.20 + 0.20 = 5.00
0.20 = 3.80
= 19
Use = 19 to find :
+ = 24; + 19 = 24; = 5
Answer: 5 nickels, 19 quarters
Hope this helps!
Answer:
19 quarters and 5 nickles
Step-by-step explanation:
19 * .25 = 4.75 .05 * 5 = .25 4.75+.25= 5

Jim paid a gym membership fee of $50, plus $20 per month. Jim has paid a total of $290 to thegym. Which equation matches this situation?
Answer:
50+20x=290 or 50+(20x12)=290
Step-by-step explanation:
Answer:
50 + 20m = 290
Step-by-step explanation:
The answer is 50 + 20m = 290, because Jim paid a membership fee that was $50. Then each month he paid $20 because of his new membership. Jim never paid $50 a month, that was only his starter fee, but then gradually paid $20 every month so it would be 20m. Hope this helped.

how do you solve for x
the similarity statement is abc~ xyz
Answer:
m<X= 36.87 degrees
Step-by-step explanation:
Since the triangle abc and xyz are similar, hence;
m<C = m<Y
90 = x - 5
Add 5 to both sides
90+5 = x-5+5
95 = x
Swap
x = 95
m<Y = x - 5
m<Y = 95 - 5
m<Y = 90
Find m<X
Using the SOH CAH TOA
Opposite to m<X = YZ = 6
Adjacent = 8
Tan M<X = opp/adj
Tan m<X = 6/8
m<X = arctan(6/8)
m<X= 36.87 degrees

Felipe is a software salesman. His base salary is $2200, and he makes an additional $70 for every copy of English is Fun he sells. Let P represent his total pay in dollars), and let N represent the number of copies of English is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 26 copies of English is Fun.
Multiplying N by what he makes for each one and add to his salary:
P = 70N + 2200
Replace n with 26 and solve:
P = 70(26) + 2200
P = 1820 + 2200
P = 4020
He earns $4,020
Answer:

Step-by-step explanation:
A rectangular goat pen has an area of 32 square meters and a perimeter of 24 meters. What are the dimensions of the pen?
Answer:
Breadth is 4 m and length is 8m
Step-by-step explanation:
Area of the rectangle = Length * breadth
Area of the rectangular goat pen= 32 square meters
Perimeter of the rectangular goat pen = 24 meters
Perimeter of the rectangle = 2(length + breadth)
24= 2(l+b)
12= length + breadth
12- breadth = length ----------- equation A
Area = l*b
32= l*b
32= (12- b) *b
32= 12b- b²
b²-12b+32= 0------------------- equation B
Solving the quadratic equation by factorization
b²- 8b- 4b+32= 0
b(b-8) -4(b-8)= 0
(b-8) = 0
(b-4)= 0
b= 8 or b=4
As breadth is usually smaller than length then putting b= 4 in equation A
gives
12- breadth = length
12-4= length
length = 8
Hence breadth is 4 m and length is 8m

Felix drew two box-and-whisker plots to compare the same sets of data:
In the form of a paragraph, use complete sentences to describe some of the differences in the prices of the two sets of books. Refer to the box and whisker plots to justify your answer.
Answer:
In the first data set, there is little variation in the prices. Half of the books cost between $3 and $7, with one-fourth of the books priced between $5.40 and $7. This is easy to read from the graph, since the medians divide the data into 4 equal groups.
In the second data set, there is a large range of prices. There is no simple description of the data. Looking at the graph, there are 3 "halves" of the data: $7 to $66 or $59, $26.80 to $81.40 or $54.50, and $66 to $99 or $33. This range of values does not give much information about general book prices.

Linda is 3 1/years younger than Rose. Joahn is 8 1/3years older than Linda. To the nearest year, what is the difference in Rose's age and Joahn's age?
Answer: 5 years
Step-by-step explanation:
Given
Linda is [tex]3\ \frac{1}{3}\ yr[/tex] younger than Rose
Johan is [tex]8\ \frac{1}{3}\ yr[/tex] older than Linda
Suppose the age of Rose is [tex]x[/tex]
So, Linda's age
[tex]x-\dfrac{3\times3+1}{3}=x-\dfrac{10}{3}[/tex]
Johan's age
[tex]x-\dfrac{10}{3}+\dfrac{8\times3+1}{3}=x+\dfrac{-10+25}{3}\\\\x+\dfrac{15}{3}=x+5[/tex]
Difference between the Rose's and Johan's age is
[tex]\Rightarrow x+5-x=5\ yr[/tex]

Equation C: y = 6x + 9 Equation D: y = 6x + 2 How many solutions are there to the given set of equations?
Answer:
No solution
Step-by-step explanation:
Equation C :
y = 6x + 9
Equation D :
y = 6x + 2
By comparing both the equations with slope-intercept form of the equation,
y = mx + b
Where, m = Slope of the line
And b = y-intercept
Slopes of both the lines C and D are common as 6,
Therefore, both the lines will be parallel.
And the set of parallel lines has no solution.
Therefore, given set of equations have no solution.

Answer:
Read answer below :)
Step-by-step explanation:
So you know that the height is 12 cm, and the base is 27 cm at full. When they show you half, that's 13.5. So, having three sides in the entire base-length of 27 cms, you'll divide 27 by 3, in which case you get 9. Each the the base lengths are 9.
So the formula for volume is length * width * height. Knowing the width (13.5), the length (9), and height (12), multiply them. Your final answer is 1458 for all of it. For one side, divide by 6.
Hope this helps
