The two true statements are the second statement (both lines contain the point (0,0)) and the fourth statement (If the Wilson family buys 3 pizzas, they will get more slices than the Hernandez family).
Which is the correct statement?
First, we know that the Hernandez family orders 3 large pizzas, such that they cut each pizza in the same number of slices, getting a total of 24 slices.
Then the number of slices that they get for each pizza is:
24/3 = 8
So from each large pizza, they get 8 slices.
So the relation between the number of pizzas bought (x) and the number of slices (y) is:
y = 8*x
In the other hand for the Wilson family we have the relation:
y = 10*x
Where y and x are the same ones as the defined above.
Then the true statements are:
"If the Wilson family ordered 3 large pizzas from the same restaurant as the Hernandez family, they would have more slices than the Hernandez family after each family cut their pizzas into slices."
This is true because Wilson family cuts each pizza in 10 slices, while the Hernandez family cuts each pizza in 8 slices.
"For each family, a graph of the relationship between number of pizzas, x, and number of slices, y, goes through the point (0, 0) and is a straight line."
The point (0, 0) means that if they buy 0 pizzas, they get 0 slices, which is true, so both relations contain this point.

Which equation and graph show the number of days, d, as a function of the population
p, in thousands?
Answer: C. [tex]p = 2^{d}[/tex]

here is the histogram of a data distribution. All class widths are 1.
what is the median of the distribution?
The median of the data is 5 if the all class widths are 1, option (C) is correct.
What is the median?A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
In the histogram, 15 data values are given:
1, 2, 2, 3, 3, 3, 4, 5, 6, 6, 7, 7, 7, 8, 9
The mid-value is 5 which is on the 8th place
Thus, the median of the data is 5 if the all class widths are 1, option (C) is correct.

A spherical balloon is inflated with gas at the rate of 500 cubic centimeters per minute. How fast is the radius of the balloon increasing at the instant the radius is 70 centimeters
Using implicit differentiation, it is found that the radius is increasing at a rate of 0.0081 cm per minute.
What is the volume of a sphere?The volume of a sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
Applying implicit differentiation, the rate of change is given by:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
In this problem, we have that:
[tex]\frac{dV}{dt} = 500, r = 70[/tex]
Hence the rate of change of the radius is given as follows:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
[tex]19600\pi\frac{dr}{dt} = 500[/tex]

A 6-inch personal pizza has 570 calories. Determine the number of calories in the 14-inch pizza. Round your answer to the nearest calorie.
Answer:
3103 calories
Step-by-step explanation:
We presume the number of calories is proportional to the area of the pizza. The ratio of areas is the square of the ratio of the linear dimensions, so the number calories in the larger pizza is ...
(14/6)² × 570 calories = 3103 1/3 calories
There are about 3103 calories in the 14-inch pizza.

4
Answer:
y = (-1/4)x + (13/4)
Step-by-step explanation:
The general structure of an equation in slope-intercept form is:
y = mx + b
In this form, "m" represents the slope and "b" represents the y-intercept.
Remember that in a point (-3,4) you have an "x" and "y" value. As such, you have been given values for the "x", "y", and "m" variables. Therefore, you can plug these values into the general structure to find the value of "b".
y = mx + b <---- General structure
y = (-1/4)x + b <---- Plug (-1/4) in "m"
4 = (-1/4)(-3) + b <---- Plug in values from point
4 = (13/4) + b <---- Multiply (-1/4) and -3
(13/4) = b <---- Subtract (13/4) from both sides
Now that you know the value of "m" and "b", you can determine the formula.
y = (-1/4)x + (13/4)

Question:
A parallelogram fencing area is to be constructed for a general swimming pool area. The total perimeter of the parallelogram fence is 220m. If one of the lengths is 50m, determine the dimension of the other length and draw it out.
If you want more information let me know
Answer:
The other length is 60m.
Step-by-step explanation:
If you look at the shape of a parallelogram, you will see that a parallelogram has two parallel sides. So, if the total perimeter is 220m, then 50m and 50m together would be 100m, so 220- 100= 120m left to fill in both sides left. so, 120÷2= 60m. 60m is the other length.

We are asked to find the two integers, given that they are consecutive, and their sum is 65.
[tex]\triangle~\fbox{\bf{KEY:}}[/tex]
Consecutive integers are right next to each other, like 12 and 13. or 65 and 66.Let the first integer be x, and let the second integer be x+1.
Their sum is 65. Let's set up our equation:
[tex]\longmapsto\sf{x+x+1=65}[/tex]
Combine like terms:
[tex]\longmapsto\sf{2x+1=65}[/tex]
Subtract 1 from both sides of the equal sign:
[tex]\longmapsto\sf{2x=64}[/tex]
Divide both sides by 2:
[tex]\longmapsto\sf{x=32}[/tex]
To find the second integer, subtract the first integer from the sum of the two integers:
[tex]\longmapsto\pmb{65-32}[/tex]
[tex]\longmapsto\pmb{33}[/tex]
The integers are: 33 and 32.

The area of a rectangle is 44 square units. Its length measures 4 units. Find the length of its diagonal. Round to the nearest tenth of a unit.
Answer:
√(137)
Step-by-step explanation:
First, you will need to find the other side length.....then you can use the Pythagorean Theorem to find the diagonal:
L x W = 44
4 x W = 44
W =11
Now the Pythag, Theorem:
diagonal^2 = 4^2 + 11^2
d^2 = 16+121
d^2 = 137
d = √(137)
Answer:
about 11.7 units (Pls mark me as brainy)
Step-by-step explanation:
Find the width:
length⋅width= area
4w=44 Plug in known values.
4w/4=44/4 Divide both sides by 4
w=11
Find the diagonal:
(4)^2+(11)^2= c^2 Use the Pythagorean Theorem.
16+121= c^2 Simplify.
137=c^2 Simplify.
±√137= √c^2 Square root both sides.
11.704699...= c Simplify. Ignore the negative root, as the length must be positive.
11.7≈ c Round to the nearest tenth.
The length of the diagonal is 11.7 units.
