Your friend claims that she has a bag of 30 coins containing nickels, dimes,
and quarters. The total value of the 30 coins is $3. There are twice as many
nickels as there are dimes. Is your friend correct?
9514 1404 393
Answer:
No
Step-by-step explanation:
If all 30 coins were nickels and dimes, there would be 10 dimes and 20 nickels, for a total value of $2.00. Trading a dime and 2 nickels for an equal number of quarters raises the value to $2.00 -0.10 -2(0.05) +3(0.25) = $2.55.
That is, each such trade adds $0.55 in value to the total amount. Since the original difference of $3.00 -$2.00 = $1.00 is not evenly divisible by $0.55, there cannot be twice as many nickels as dimes.
__
For 30 coins, possible numbers of {nickels, dimes, quarters} are ...
{21,2,7}, {18,6,6}, {15,10,5}, {12,14,4}, {9,18,3}, {6,22,2}, {3,26,1}, {30 dimes}
Note that we can have 1.5, 3, or 10.5 times as many nickels as dimes, but not 2 times as many.

1.The entry tickets at a community fair cost $5 for children and $10 for adults. On a certain day 1000 people entered in the fair and \$7,100is collected. How many adults and how many children were at the fair? Please answer
Answer:
The number of adult that were at fair are 480 adults
The number of children that were at fair are 580 children
Step-by-step explanation:
The given parameters are;
The entry tickets cost for children = $5
The entry ticket cost for adult = $10
The number of people that entered the fair on a certain day = 1,000
The amount collected for entry tickets sold = $7,100
Let 'x' represent the number of children that bought tickets and were at fair, and let 'y' represent the number of adults that bought tickets and were at the fair, we have;
x + y = 1,000...(1)
5·x + 10·y = 7,100...(2)
Making 'y' the subject of both equations gives;
For equation (1)
y = 1000 - x...(3)
For equation (2)
10·y = 7,100 - 5·x
y = (7,100 - 5·x)/10 = 710 - x/2
y = 710 - x/2...(4)
Equating both values of 'y' from equation (3) and equation (4), we have;
1000 - x = 710 - x/2
1000 - 710 = -x/2 + x = x/2
290 = x/2
x = 580
The number of children that bought tickets and were at fair = x = 580 children
From equation (3), y = 1,000 - x = 1,000 - 580 = 420
y = 480
The number of adult that bought tickets and were at fair = y = 480 adults.
Malik and Erin run the corn harvester for Mr. Avery. Malik and Erin harvest about 2 1/3 acres' worth of corn each day. They only have 10 1/22 days to harvest the corn. How many acres' worth of corn can they harvest for Mr. Avery?
Answer:
23 29/66
Step-by-step explanation:
If Malik and Erin harvest about 2 1/3 acres' worth of corn each day and they have 10 1/22 days to harvest the field, the total acres that can be harvested would be the product of 2 1/3 and 10 1/22
2[tex]\frac{1}{3}[/tex] x 10[tex]\frac{1}{22}[/tex]
Convert the mixed fractions to an improper fraction
[tex]\frac{7}{3}[/tex] x [tex]\frac{221}{22}[/tex] = [tex]\frac{1547}{66}[/tex]
Convert the improper fraction back to mixed fraction To do this, divide the numerator by the denominator, the number got would be the whole number of the mixed fraction. The remainder would be the numerator

Rose would be saving 50 dollars after 10 months. So you know that Rose got $10 in 0 months and $14 in the next month and again.This means that every month it adds up to another $4. If you want to find the total or 10 months keep on add 5 4 times which is 20. Then add 30 from the 0-5 months and which gives you $50. So Rose would be saving up 50 bucks in 10 months.

Three regular hexagons are put together to make a larger shape. The perimeter of one of the regular hexagons is 18cm. Find the perimeter of the larger shape.
Answer:
steps below
Step-by-step explanation:
2 kinds of larger shapes can be make
kind 1: 18 x 4 x 3 = 216 cm
kind 2: 18 x (5+5+4) = 252 cm
The perimeter of the larger shape formed by putting three regular hexagons together is 216 cm.
When three regular hexagons are put together to form a larger shape, they form a regular hexagon with an equilateral triangle at each end.
The perimeter of the larger shape can be calculated as follows:
Perimeter of larger shape = Perimeter of hexagon + Perimeter of equilateral triangle
Since the hexagon has six sides of equal length, its perimeter is [tex]\(6 \times 18 \, \text{cm} = 108 \, \text{cm}\)[/tex].
Each equilateral triangle has three sides of equal length, and each side of the equilateral triangle is equal to one side of the hexagon.
So, the perimeter of each equilateral triangle is [tex]\(3 \times 18 \, \text{cm} = 54 \, \text{cm}\)[/tex].
Since there are two equilateral triangles, the total perimeter contributed by the equilateral triangles is [tex]\(2 \times 54 \, \text{cm} = 108 \, \text{cm}\)[/tex].
Finally, to find the perimeter of the larger shape, add the perimeters of the hexagon and the two equilateral triangles:
Perimeter of larger shape = 108 cm + 108 cm = 216 cm
Thus, the perimeter of the larger shape is [tex]\(216 \, \text{cm}\)[/tex].

A model car has a scale factor of 1/64. The diameter of a tire on the model is 0.43 inches. So, the diameter of the tire on an actual car must be inches. Your answer must be correct to one decimal place.
Answer:27.52 inches
Step-by-step explanation:
Given
Scale factor [tex]\frac{1}{64}[/tex] i.e.
[tex]\dfrac{\text{Model}}{\text{Prototype}}[/tex]
The diameter of the model tire is 0.43 inches
Scale factor = [tex]\dfrac{\text{dia. of model}}{\text{dia. of actual car}}[/tex]
[tex]\frac{1}{64}=\frac{0.43}{D}\\D=64\times 0.43=27.52\ \text{inches}[/tex]

Police chases a driver. The police is 1 mile behind the driver. The speed of the police is 90 mph, and the speed of the chased car is 85 mph. How long will it take for the police to catch up with the car?
Answer:
0.20 hour
Step-by-step explanation:
According to the problem, computation of the given data are as follows,
Speed of police = 90 mph
Speed of chased car = 85 mph
Distance to be chased = 1 mile
So, we can calculate the time to catch by using following formula:
Time required = Distance between two cars ÷ (Speed of Car A - Speed of Car B)
= 1 ÷ ( 90 - 85)
= 1 ÷ 5
= 0.20 hour
