Five people will equally share 2 pizzas.How much pizza will each person will receive?
Answer:
⅖ pizza
Step-by-step explanation:
Divide each pizza into five slices.
Then there will be 10 slices, and each person will get two slices.
Two slices = ⅖ pizza
Each person will receive ⅖ pizza.
Each of the five people will receive 2/5 of a pizza when two pizzas are shared equally amongst them.
Explanation:The student asked how much pizza each person will receive if five people are sharing two pizzas equally. To answer this, we divide the total number of pizzas by the number of people. Since there are 2 pizzas and each pizza is usually considered to be 1 whole, when split among 5 people, each person will get 2/5 of a pizza.

Gravity on the moon = 1.6 m/s^2 Gravity on Mars = 3.7 m/s^2
a) 1 kg object on earth
b) 2.75 lbm object on the moon
c) 1.25 lbf object on the moon
d) 15 N object on earth
e) 15 N object on Mars
The answer is C.) i think
Answer:
e) 15 N object on Mars
d) 15 N object on earth
b) 2.75 lbm object on the moon
a) 1 kg object on earth
c) 1.25 lbf object on the moon
Step-by-step explanation:
Mass is the amount of mass that a certain object has, it differs from its weight because the weight depends of the gravity or the force that is been applied to the object towards the planet.
To obtain the mass a 15N object on mars you have to divide the 15N by the gravity of mars this would be like this:
Mass:[tex]\frac{15}{3.7}[/tex]= 4.05kg
To obtain the mass of a 15 N objecto on the earth you divide 15N by 9.8 [tex]\frac{m}{s^{2} }[/tex] which is the gravity on earth.
Mass:[tex]\frac{15}{9.8}[/tex]= 1.53 kg
To calculate the mass of a 2.75 lbm object on the moon you just have to convert it to kg.
Mass in kg: 2.75*.453= 1.24 kg
Then the 1 kg mass object on the earth.
And last the 1.25 lbf object on the moon you just convert it to kilograms.
Mass in kg: 1.25*.138=.172kg

1. Preliminaries Remember the setup: We (the RAF in World War II) want to know the number of warplanes fielded by the Germans. That number is N. The warplanes have serial numbers from 1 to N, so N is also equal to the largest serial number on any of the warplanes. We only see a small number of serial numbers (assumed to be a random sample with replacement from among all the serial numbers), so we have to use estimation. Question 1.1 Is N a population parameter or a statistic? If we compute a number using our random sample that's an estimate of N, is that a population parameter or a statistic?
Answer:
N is a population parameter; the computation using an estimate of N is a statistic.
Step-by-step explanation:
A parameter is a measure of a population. The number of warplanes fielded total is N; this makes it the population. Thus N is a parameter.
A statistics is a measure of a sample. The number computed using an estimate of N would be based on a sample, since it is an estimate of N; this makes it a statistic.

What is the length of the missing side of the triangle in simplest radical form? the figure is not drawn to scale.
Answer:
option (c)
4√34
Step-by-step explanation:
Given in the question is a right angle triangle
height of triangle = 20 cm
base of triangle = 12 cm
To find the length of missing side of the triangle we will use pythagorus theorem
hypotenuse² = height² + base²hypotenuse² = 20² + 12²
hypotenuse² = 400 + 144
hypotenuse² = 544
take square root on both sides
√hypotenuse² = √544
hypotenuse = 4√34 cm
Hence, the length of missing side of the triangle is4√34 cm

Graph for [tex]f(x) = \frac{(2x+3)(x-6)}{(x+2)(x-1)}[/tex]
Answer:
The graph is attached below
Step-by-step explanation:
The function has three asymptotes. Before we can graph the function, we can find them.
Vertical asymptotes in the values that make the denominator zero.
The denominator becomes zero in:
[tex]x = -2\\x = 1\\[/tex]
Then the vertical asymptotes are the lines
[tex]x = -2\\x = 1\\[/tex]
The horizontal asymptote is found using limits
[tex]\lim_{x\to \infty}\frac{(2x+3)(x-6)}{(x+2)(x-1)}[/tex]
Then:
[tex]\lim_{x\to \infty}\frac{(2x^2-12x +3x -18)}{x^2-x+2x-2}[/tex]
We divide the numerator and the denominator between the term of greatest exponent, which in this case is [tex]x ^ 2[/tex]
The terms of least exponent tend to 0
[tex]\lim_{x\to \infty}\frac{(2\frac{x^2}{x^2}-0 +0 -0)}{\frac{x^2}{x^2}-0+0-0}\\\\\lim_{x\to \infty}\frac{2}{1} = 2\\\\[/tex]
The function has a horizontal asymptote on y = 2 and has no oblique asymptote

John picks 150 apples on the first day, 250 on the second day, 350 on the third day, and so on. How many apples does John pick on the 10th day?
1250
1150
1050
950
To determine the number of apples John picks on the 10th day, we use the formula for the nth term of an arithmetic sequence. Given the first day's pick at 150 apples and an increase of 100 apples each day, we find that John picks 1050 apples on the 10th day.
Explanation:An arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant difference to the preceding term.
In this case, the first term (the number of apples picked on the first day) is 150, and the common difference (the increase each day) is 100 apples.
To find the number of apples picked on the 10th day, we use the formula for the nth term of an arithmetic sequence, which is:
an = a1 + (n - 1) × d
Where an is the nth term, a1 is the first term, n is the term number, and d is the common difference. For the 10th day:
a10 = 150 + (10 - 1) × 100
a10 = 150 + 9 × 100
a10 = 150 + 900
a10 = 1050
Therefore, John picks 1050 apples on the 10th day.
Place the circles in order from the circle with the largest area to the circle with the smallest area.
a circle with a diameter
of 8 metersa circle with a radius
of 7 metersa circle with a circumference
of 37.68 metersa circle with a diameter
of 16 meters
Answer:
Diameter 16, radius 7, circumference 37.68, diameter 8
Step-by-step explanation:
Largest area will be in a circle with the largest radius. So let's find all radii.
d = 8, so r = 4;
r = 7;
circumference = 2pi*r = 37. 68, so r = 6
diameter 18, so r = 8
(6CQ) Evaluate the limit, or state that the limit does not exist. 2n+7n/13n

n will cancel out on both sides
so,
9/13 will remain

Explain how to determine if the number is a solution to the equation. 56 = 8 + 4n for n = 6
To determine if the number is a solution to the equation, we have to substitute n with the number given.
56= 8 + 4(6)
56= 8 + 24
56= 32
So no, the number is not a solution to the equation.
The number is a solution of a linear equation if both sides of the equation namely RHS and LHS are equivalent.
What is the solution to a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, the equation as 56 = 8 + 4n and to verify for n=6

Solve the system of equations using the substitution method. Y = 7x – 16, y = 2(2x – 5) What is the solution? ( , )
Answer is ( 2, -2 ) so x=2 and y=-2
Answer:
(2,-2)
Step-by-step explanation:
This pair of linear equations may be solved simultaneously by using the elimination method. This will involve ensuring that the coefficient of one of the unknown variables is the same in both equations. It may be solved by substitution in that one of the variable is made the subject of the equation and the result is substituted into the second equation.
Given that Y = 7x – 16, y = 2(2x – 5)
Equating both equations
7x - 16 = 4x - 10
7x -4x = 16 - 10
3x = 6
x = 2
Substituting the value of x into Y = 7x – 16
y = 7(2) - 16
y = 14 - 16
y = -2
hence
(x,y) = (2,-2)

Answer:
1. The area of the triangle PQR is 40 cm^2.
2. 321.4 cubic cm
Step-by-step explanation:
1. We are given two triangles, ABC and PQR, which are similar to each other.
Given that area of the triangle ABC is [tex]40cm^2[/tex], we are to find the area of the triangle PQR.
For that, we can use the ratio method:
[tex] \frac { P Q R } { 4 0 } = \frac { 6 } { 4 } [/tex]
Area of triangle PQR = [tex] \frac { 6 \times 40 } { 4 } = 60cm^2 [/tex]
2. We are given the diameter of a spherical model to be 8.5 cm so its radius will be 4.25 cm.
Finding the volume of the spherical model as we know that the volume of a sphere is given by:
