PLEASE HELP Jax is surveying the number of children in restaurants. One restaurant has 7 children and a total of 42 customers. The next restaurant has 60 customers. Based on his survey, how many can he predict will be children?
A. 25
B. 10
C. 360
D. 5
Answer:
B.10
Step-by-step explanation:
42÷7=1. 1 child for every 6 customer. 60÷6= 10
Answer:
B
Step-by-step explanation:
If the first restaurant had 7 children within 42 customers, then we can divide 42 by 7 to get 6, which means 1 in 6 customers are children. If we apply this to the next restaurant, we will divide 60 by 6 to get 10.
This means there are 10 children in the second restaurant, so the answer is B.

Answer:
The asteroids are mostly found in the broad space between Mars and Jupiter, a region of the solar system called the asteroid belt. Asteroids are too small to be seen without a telescope; the first of them was not discovered until the beginning of the nineteenth century.
Discovery and Orbits of the Asteroids
In the late 1700s, many astronomers were hunting for an additional planet they thought should exist in the gap between the orbits of Mars and Jupiter. The Sicilian astronomer Giovanni Piazzi thought he had found this missing planet in 1801, when he discovered the first asteroid (or as it was later called, “minor planet”) orbiting at 2.8 AU from the Sun. His discovery, which he named Ceres, was quickly followed by the detection of three other little planets in similar orbits.

Dale polled the 2 fastest swimmers on the swim team.
Is this sample of the swimmers on the swim team likely to be representative?
Answer as Yes or No
Reason:
Dale is biased toward the two fastest people in the group, but is leaving out the rest of the swimmers who may not be so fast. The people left out may be very distant from the top two swimmers. Therefore, Dale has not picked a representative sample.
As an example with numbers, let's say we had these average speeds in mph: {1, 2, 3, 4, 20, 30}. Of course these are just hypothetical examples and not based on actual realistic speeds; however, the example should still suffice.
That data set shows the average is closer to 2 and 3 than it is to 20 and 30. Dale polling the fastest people greatly skews the mean larger than it should be.
To get a better more representative sample, Dale should randomly pick 2 people regardless if they are the top two swimmers or not. He can pick the names out of a hat, or use a computer program to generate random numbers.

Step-by-step explanation:
Find the mean temperature of both cities (the workings would take up too much space but to find the mean add the average daily temperature for each month together then divide the answer by 12. This means that the mean for city A is 46.5 degrees Fahrenheit and for City B it is 64.9 degrees Fahrenheit.For the range, you subtract the lowest daily average temperature in the month from the highest one, therefore for City A it is 90-2=88 degrees Fahrenheit and for City B it is 88-30=58 degrees Fahrenheit.From finding out the mean temperature and range for both cities, that allows you to rule out all the statements as false except for C and DWhoever answers correctly can have brainliest

Write the number for nine million seven hundred thousand
Answer:
9,700,000.
Explain:
9 goes in the 1,000,000th place, and 700 would be placed right behind the 9's comma. Therefore, 9,700,000
Answer: 9,700,000
In order to answer this you should start by writing out one million. By doing this, you can find out where you ones, hundreds, thousands, and millions place is. Then input what you know. The nine would go in the millions place, then the 7 would go in the thousands place.

Solve 5x-10=3x+2. Explain.
Answer:
6[tex] \: [/tex]
Step-by-step explanation:
It is given an equation and we are to find the value of x.
[tex] \: [/tex]
Given Equation :
[tex] \\ {\longrightarrow \qquad{ \sf{5x-10=3x+2}}} \\ \\ [/tex]
Subtracting 3x from both sides we get :
[tex]\\ {\longrightarrow \qquad{ \sf{5x-10 - 3x=3x - 3x+2}}} \\ \\ [/tex]
[tex] {\longrightarrow \qquad{ \sf{2x-10=2}}} \\ \\ [/tex]
Adding 10 to both sides we get :
[tex] \\ {\longrightarrow \qquad{ \sf{2x-10 + 10=2 + 10}}} \\ \\ [/tex]
[tex] {\longrightarrow \qquad{ \sf{2x=12}}} \\ \\ [/tex]
Dividing both sides by 2 we get :
[tex] \\ {\longrightarrow \qquad{ \sf{ \frac{2x}{2} = \frac{12}{2} }}} \\ \\ [/tex]
[tex] {\longrightarrow \qquad{ \frak{ \pmb{x=6}}}} \\ \\ [/tex]
Therefore,
The value of x is 6.Answer:
= 6-
Step-by-step explanation:

What is the solution to this inequality?
−4x − 8 > −20
Question 7 options:
x > −3
x < −3
x > 3
x <3
Answer:
[tex]\boxed{\sf{D. \quad x < 3}}[/tex]Step-by-step explanation:
It is necessary to isolate the term of x from one side of an inequality to find its solution.
-4x-8>-20First, add by 8 from both sides.
[tex]\sf{-4x-8+8 > -20+8}[/tex]
Solve.
-20+8=-12
Rewrite the problem down.
[tex]\sf{-4x > -12}[/tex]
Multiply by -1 from both sides.
(-4x)(-1)<(-12)(-1)
Solve.
Multiply the numbers from left to right.
(-12)(-1)=12
4x<12
Divide by 4 from both sides.
4x/4<12/4
Solve.
Divide the numbers from left to right.
12/4=3
x<3
Therefore, the correct answer is D. x<3 (last option).I hope this helps you! Let me know if my answer is wrong or not.
Answer:
Option D.
Why is this the case, though?These equations prove it true.
[tex]-4 * 2 - 8 = -16 > -20[/tex]
[tex]-4 * 1 - 8 = -12 > -20[/tex]
The only reason these two equations are correct, is because on the number line it shows: Any negative number further to the right than the last negative number is greater than that number.

Answer:
(b) Find the volume of the box using the formula .
Answer:
(c) Find the volume of the box using the formula .
Answer:
(d) How does using the volume formulas to find the volume of a rectangular prism compare to counting unit cubes? Compare your answers in parts (b) and (c) your answer in part (a) to answer the question.
Answer:
Answer:
The volume is 160
Step-by-step explanation:
Explanation: To find the volume of the rectangular prism you need to multiply 8x20. The reason is because there are 20 cubes in each row (i'm sorry if i'm not good at explaining math very well). The way I found the volume was to count the amount of cubes on the side and multiply it by how many rows there were on top. So that brings me to 160. The product of 8x20. (I hope this helps, math isn't my best subject)
Answer:
V = 160 cubic inches
Given that,
Length, width and height of prism are 8 inches, 4 inches and 5 inches
The formula for the volume of a rectangular prism is given by :
So, the volume of the prism is 160 cubic inches.
