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]

= 5C2 * 7C3
= 10 * 35
= 350.
Hence there are 350 possible ways.
P.S.
5C2 = 5! / (2!3!) = 120 / (2 * 6) = 10.
7C3 = 7! / (3!4!) = 5040 / (6 * 24) = 35.

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.

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.

m<3 is a vertically opposite angle to the 95° given. therefore must = 95°
m<4 180° in a triangle. have just established m<3 as 95° have been given 47°. 180 - 95 - 47 = 38°
m<5 is vertically opposite to the 47° given so therefore = 47°
m<7 180° on a straight line 180 - 121 = 59°
m<6 180° in a triangle have previously established that m<5 = 47° and m<7 = 59°
180 - 47 - 59 = 74°

cos sec² a - cot²a=1
Answer:
We want to prove the relation:
cosec(a)^2 - cot(a)^2 = 1
where:
cosec(a) = 1/sin(a)
cot(a) = 1/tg(a) = cos(a)/sin(a)
We can start with the relationship:
cos(a)^2 + sin(a)^2 = 1
Now, let's divide by sin(a)^2 in both sides:
(cos(a)^2 + sin(a)^2)/sin(a)^2 = 1/sin(a)^2
cos(a)^2/sin(a)^2 + sin(a)^2/sin(a)^2 = (1/sin(a))^2
(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2
and remember that:
cosec(a) = 1/sin(a)
cot(a) = 1/tg(a) = cos(a)/sin(a)
Then we can write:
(cos(a)/sin(a))^2 + 1 = (1/sin(a))^2
as:
cot(a)^2 + 1 = cosec(a)^2
1 = cosec(a)^2 - cot(a)^2
And this is the relation we wanted to prove.

A theater group sells tickets to a play. If an adult ticket costs $12.50 and a child ticket costs $8.75, then how much money will the group collect by selling 70 adult tickets and 15 child tickets?
Answer:
$1,006.25
Step-by-step explanation:
If you sell 70 adult tickets at $12.50 each, use the equation
12.5*70=875
By using the same equation for kids tickets,
8.75*15=131.25
Then add the sums
875+131.25=1006.25

A monkey is swinging from a tree. On each swing she travels along an arc that is 75% as long as the previous swing arc. The total length of the arcs from her first 4 swings is 175m.
Answer:
The first swing is 64m
Step-by-step explanation:
The complete question asks for how long the first swing is.
The monkey is swinging from the tree with each swing being along an arc, where each arc is 75% of the previous arc. Also, given that its first four swings is 175cm, we can denote her first swing as y.
This means the second swing would be = 0.75y
The third would be = 0.75(0.75y) = 0.5625y
The fourth would be = 0.75(0.5625y) = 0.421875y
Since the total is 175, we have
y + 0.75y + 0.5625y + 0.421875y = 175
2.734375y = 175
y = 175/2.734375
y = 64m
