Answer:
40 children went on the cruise.
Step-by-step explanation:
This question can be solved by a system of equations.
I am going to say that:
x is the number of adults on the cruise
y is the number of children on the cruise.
57 tickets were sold:
This means that [tex]x + y = 57[/tex], and since we want the number of children y, [tex]x = 57 - y[/tex]
Each adult had to pay $22 for the cruise and each child had to pay $10. The company's total receipts were $774.
This means that:
[tex]22x + 10y = 774[/tex]
Since [tex]x = 57 - y[/tex]
[tex]22(57 - y) + 10y = 774[/tex]
[tex]1254 - 22y + 10y = 774[/tex]
[tex]12y = 480[/tex]
[tex]y = \frac{480}{12}[/tex]
[tex]y = 40[/tex]
40 children went on the cruise.
is 0.3 greater than 0.22
Answer:
Yes
Step-by-step explanation:
.3 is the same as .30, and 30 is greater then 22, therefore .3 is greater then .22

A spherical cantaloupe is cut in half. The visible cross-section has an area of 5252 in2. The volume of the cantaloupe is _____ cm3. Round your answer to the tenths place.
Answer:
V = 286319.465 cm3
Step-by-step explanation:
First, you have to find the radius to be able to find the volume of a sphere.
The equation for the area of a circle is pi r^2 so you have to so some algebra.
5252 = pi r ^2
5252/pi = r^2
1671.76352 = r^2
sqrt(1671.76352) = r
r = 40.8872048
then you do the equation for the volume of a circle which is 4/3 pi r^3
4/3 pi (40.8872048)^3
4/3 pi 68353.7373
4/3 214739.599
286319.465
V = 286319.465 cm3

Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.
What is circumference?A circumference gives the length around a circular object, it is the perimeter used for the circular objects.
Given that a circular tablecloth has a radius of 24 inches, we need to find the length around it,
So, the length around a circular object is its circumference,
We know that circumference of the circular object = π × diameter,
Diameter = 2 × radius = 48 inches.
So, the length around the circular cloth = π × 48
= 3.14 × 48
= 150.72
Hence Mrs. Lopez need to sew a piece of cloth whose length be 150.72 inches.

Solve for x. The polygons in each pair are similar.
Answer:
x = 9
Step-by-step explanation:
We need to find the value of x if the polygons in each pair are similar.
As they are similar, the ratio of their sides are equal.
The sides of first polygon are 6,12 and 4.8. On the other hand, the sides of second polygon are (2x-9) and 18.
So,
[tex]\dfrac{6}{2x-9}=\dfrac{12}{18}\\\\\dfrac{6}{2x-9}=\dfrac{2}{3}\\\\\dfrac{3}{2x-9}=\dfrac{1}{3}\\\\x=9[/tex]
So, the value of x is equal to 9.
