The admission fee at a small fair is $1.50 for children and $4.00 for adults. On a certain day, 2200 people enter the fair and $5050 is collected. How many children and how many adults attended?
Answer:
Let x be the number of children that attended.
Let y be the number of adults that attended.
x+y=2200
1.5x+4y=5050
Solving this system, our answer is:
x=1500
y=700
1500 kids attended and 700 adults attended.

Ian Duncan drove from Kajiado to Nairobi at a distance of 180km in one hour. What was the speed in m/s?
9514 1404 393
Answer:
50 m/s
Step-by-step explanation:
Ian's rate was ...
(180,000 m)/(3600 s) = 50 m/s
__
There are 1000 meters in a kilometer, and there are 3600 seconds in 1 hour. To find meters per second, divide meters by seconds.
Find the surface area of the rectangular prism. 5ft tall 5 feet long 2 feet wide
Answer:
46.25 feet squared
Step-by-step explanation:
base area = 5x2 = 10
you need to find how tall the faces of the prism are now. You can do this using the pythagorean theorem: a^2+b^2=c^2
5^2+2.5^2=c^2 and 5^2+1^2=c^2
(since it is a rectangular pyramid)
c= 5.60 and c= 5.01
now be can find the surface area of the 4 triangles
SA= 5.60x2 and SA= 5.01x5
SA=11.2 and SA= 25.05
add all the components (11.2, 25.05, 10) together to get the final surface area: 46.25
Is there anyone that can help me with this problem?
Answer:
A
Step-by-step explanation:
mnp=wxy
Answer:
1. MNP-WXY
Step-by-step explanation:
Line up each angle with the one that corresponds with it on the other triangle. (so M=W, N=X, P=Y)
Then, look at each equation and see it each one is in the right spot on each side. (So M and W should be in the same spot, N and X should be in the same spot, and P and Y should be in the same spot)
So the possible statements could be: MNP-WXY, NPM-XYW, PMN-YWX, PNM-YXW, MPN-WYX, and etc.
Sometimes, the triangles aren't lined up with each correct angle in the corresponding spot and to fix that, just flip the triangle.
(hope this helps...and makes sense :P)

1. Isaiah and Ron work together on their
math homework. Isaiah says that 3(x + 3) is
equivalent to 3x + 9. Ron says that the two
expressions are not equivalent. Sketch a model
of each expression to show who is correct.
Answer:
Step-by-step explanation:
They are equivalent. Use the distributive property.
3(x+3)
the 3 on the outside of the parenthesis is multiplied by the variable(the letter) and thenthe constant(number) inside the parenthesis.
makes and equivalent equation 3x+9

Answer:
I. p = 7
II. 17 litres
Step-by-step explanation:
I. Determination of the value of p
Mean = 17.7
p =.?
Let the number of litre be L
Let the number of motorist be M
Mean = summation LM / summation M
Summation of LM = (16×11) + (17×10) + (18×p) + (19×4) + (20×8)
= 176 + 170 + 18p + 76 + 160
= 582 + 18p
summation M = 11 + 10 + P + 4 + 8
= 33 + p
Mean = summation LM / summation M
17.7 = 582 + 18p / 33 + p
Cross multiply
17.7(33 + p) = 582 + 18p
584.1 + 17.7p = 582 + 18p
Collect like terms
584.1 – 582 = 18p – 17.7p
2.1 = 0.3p
Divide both side by 0.3
p = 2.1 / 0.3
p = 7
II. Determination of the median number of litre.
Let the number of motorist be M (i.e the frequency)
summation M = 11 + 10 + P + 4 + 8
p = 7
summation M = 11 + 10 + 7 + 4 + 8
summation M = 40
The median is the middle term i.e
Median = (summation M / 2)ᵀʰ motorist
Median = (40 / 2)ᵀʰ motorist
Median = 20ᵀʰ motorist
Considering the table in the question above, the 20ᵀʰ motorist has 17 litres.
Therefore, the median number of litres is 17 litres.

The diameter, D, of a sphere is 6.4 mm. Calculate the sphere's volume, V.
Use the value 3.14 for pi and round your answer to the nearest tenth. (Do not round any intermediate computations.)
Answer:
Volume of sphere = 1.3 * 10^-7 cubic meters.
Step-by-step explanation:
Given the following data;
Diameter, D = 6.4 mm to meters = 6.4/1000 = 0.0064 meters.
But, Radius = diameter/2
Radius = 0.0064/2 = 0.0032 meters.
π = 3.14
To determine the volume of sphere, we would use the formula;
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Substituting into the equation, we have;
[tex] V = \frac {4}{3} * 3.14 * 0.0032^{3} [/tex]
[tex] V = 4.186666667 * 3.2768 * 10^{-8} [/tex]
Volume of sphere = 1.371886933 * 10^-7 cubic meters.
To the nearest tenth;
Volume of sphere = 1.3 * 10^-7 cubic meters.
750 ml bottle of medicine costs $ 1.80 A 1.4 litre of the same medicine costs $3.50
a) Work out the cost for each bottle , in cents per milliliter .
b) Which bottle is better value for money ?
Answer:
The 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.
Step-by-step explanation:
Given that 750 ml bottle of medicine costs $ 1.80, while 1.4 liter of the same medicine costs $ 3.50, to work out the cost for each bottle in cents per milliliter, and determine which bottle is better value for money, the following calculations must be done:
1.80 / 750 = 0.0024
3.50 / 1,400 = 0.0025
Thus, the 750-milliliter bottle costs $ 0.0024 per milliliter, while the 1.4-liter bottle costs $ 0.0025 per milliliter, making the 750-milliliter bottle a better value.

Which of the following options have the same value as 40% of 84?
Answer:
33.6
Step-by-step explanation:
84(0.4) = 33.6
.....
Answer:
40% of 84 is 33.6
Step-by-step explanation:
No following options are listed, but I will solve for 40% of 84
First set these up into an equation
40/100 = x/84
Cross multiply
40 × 84 = 100 × x
3360 = 100x
Divide both sides by 100 to isolate the variable
33.6 = x

los conjuntos numericos se relacionan entre si, los irracionales son caso aparte de los conjuntos numericos, cual sera la razon por lo que esto sucede?
Answer:
Los conjuntos numéricos que se relacionan entre sí son:
Naturales, enteros y racionales.
Los números naturales son aquellos números que se pueden escribir como sumas de 1.
Los números enteros son todos los números naturales, y agregamos el número cero y los números negativos.
Los números racionales son aquellos números que se escriben como cociente de dos números enteros. Acá también podés notar que:
7 = 7/1
entonces todo número entero se puede escribir como el cociente de dos enteros, lo que implica que el conjunto de los números racionales también engloba al conjunto de los enteros.
Entonces si N es el conjunto de los números naturales, Z es el conjunto de los números enteros, y Q es el conjunto de los números racionales, tenemos que:
N ⊂ Z ⊂ Q.
Ahora por otro lado, el conjunto de los números irracionales es aquel que no se puede escribir como cociente de dos números enteros. Con esto ya podemos concluir que no existe ningún elemento compartido entre ninguno de los conjuntos anteriores y este conjunto, y esto se debe a la definición de número irracional, como no se puede construir como el cociente de números enteros, entonces no hay forma de relacionarlo con ninguno de los otros conjuntos.
