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.

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

= 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.

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.

Answer:

105 degrees

Step-by-step explanation:

The angle of a straight line is 180 degrees. Since we need to find the angle for 3, it is 180-75 which is 105 degrees.

Answer:

m<1 51°

m<2 34°

m<3 95°

m<4 38°

m<5 47°

m<6 74°

m<7 59°

m<1 there are 180° on a straight line. 180-129= 51°

m<2 there are 180° in a triangle. we have been given 95° and have just established that m<1 is 51° 180- 95- 51 = 34°

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°

The number of well-done burgers the restaurant served will be 24.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

John's burgers cook its burgers either well done or medium. The restaurant served 80 burgers last night, 30% of which were well done.

Then the number of well-done burgers the restaurant served will be given as,

⇒ 30% of 80

⇒ 0.30 x 80

⇒ 24

The number of well-done burgers the restaurant served will be 24.

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

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.
