Cia collected the most money
Jen collected the least money.
Step-by-step explanation:
Let Jen collected money = x
Mark collected money = 23x
while Cia collected money = 212 (23x)
So, we can observe that Cia and Mark collected more money than Jen as Jen money is multiplied by 23 to make Mark's money and Mark's money is multiplied by 212 to get Cia's Money.
So, Cia collected the most money
Jen collected the least money.
Answer:
cai has the most
jen has the least money

find the values of the following, giving your answers as fractions
4^(-1)
2^(-3)
3^(-4)
Fractions
The values are [tex]\frac{1}{4} , \frac{1}{8} , \frac{1}{81}[/tex]
Step-by-step explanation:
As we know the fractions whose numerators are 1 can be represented in exponents and vice versa provided that the power of the exponent is (-1) ,
like 1/a = a^(-1)
[tex]\frac{1}{a}[/tex] = [tex]a^{-1}[/tex]
so accordingly
a)
4^(-1) or [tex]4^{-1}[/tex] can be represented exponentially as ¼ .
⇒ [tex]\frac{1}{4}[/tex]
Part b)
2^(-3) or [tex]2^{-3}[/tex]
We can simplify the exponent so that the power should be equal to -1.
And, so [tex]2^{3}[/tex] = 8
So we can write the above the expression as 8^(-1) or [tex]8^{-1}[/tex]
So the fraction corresponding to it is [tex]\frac{1}{8}[/tex].
⇒ [tex]\frac{1}{8}[/tex]
Part c)
3^(-4) now we can simplify the exponent so that the power of the exponent is -1.
And thus , (3 ^4)^(-1) = 81^(-1) = [tex]\frac{1}{81}[/tex]
So the fraction obtained is [tex]\frac{1}{81}[/tex].
⇒ [tex]\frac{1}{81}[/tex]
The values are [tex]\frac{1}{4} , \frac{1}{8} , \frac{1}{81}[/tex]

Given:
The given expression is [tex]\left(\frac{3}{10}\right)^{3}[/tex]
We need to determine the value of the given expression.
Value of the expression:
Let us determine the value of the expression.
The value of the expression can be determined by simplifying the given expression.
Applying the exponent rule, [tex]\left(\frac{a}{b}\right)^{c}=\frac{a^{c}}{b^{c}}[/tex], we get;
[tex]\left(\frac{3}{10}\right)^{3}=\frac{3^{3}}{10^{3}}[/tex]
Since, the value of 3³ is 27 and the value of 10³ is 1000, substituting these values, we get;
[tex]\frac{27}{1000}[/tex]
Hence, the value of the expression is [tex]\frac{27}{1000}[/tex]
Thus, Option b is the correct answer.

Mark lives 5,000 feet away from school and walks at a steady rate of 250 feet per minute, so it takes him 20 minutes to walk to school.
Explanation:Step-by-Step Explanation
Mark lives 5,000 feet from school and walks at a steady rate of 250 feet per minute. To calculate the time it takes for Mark to walk to school, we divide the total distance by his speed:
Time = Distance \/ Speed
Time = 5,000 feet \/ 250 feet per minute
Time = 20 minutes
Thus, Mark takes 20 minutes to walk to school from his home.

Liam is making barbecue ribs over a fire. The internal temperature of the ribs when he starts cooking is 40°F. During each hour of cooking, the internal temperature will increase by 25%. The ribs are safe to eat when they reach 165°F.
Use the drop-down menus to complete an inequality that can be solved to find how much time, t, it will take for the internal temperature to reach at least 165°F.
Answer: You need to wait at least 6.4 hours to eat the ribs.
t ≥ 6.4 hours.
Step-by-step explanation:
The initial temperature is 40°F, and it increases by 25% each hour.
This means that during hour 0 the temperature is 40° F
after the first hour, at h = 1h we have an increase of 25%, this means that the new temperature is:
T = 40° F + 0.25*40° F = 1.25*40° F
after another hour we have another increase of 25%, the temperature now is:
T = (1.25*40° F) + 0.25*(1.25*40° F) = (40° F)*(1.25)^2
Now, we can model the temperature at the hour h as:
T(h) = (40°f)*1.25^h
now we want to find the number of hours needed to get the temperature equal to 165°F. which is the minimum temperature that the ribs need to reach in order to be safe to eaten.
So we have:
(40°f)*1.25^h = 165° F
1.25^h = 165/40 = 4.125
h = ln(4.125)/ln(1.25) = 6.4 hours.
then the inequality is:
t ≥ 6.4 hours.
Answer:
40 × 1.25 ^ t greater or equal to ( >) 165

What 2 pieces of mathematical information do a table, a graph, and an equation have in common?
Answer:
Trends:
In the graph or a table you easily can see trends in the data, for example, parts where if x increases also does y, or things like that.
Of course you, with some mathematical knowledge, also can notice those things when you have the equation, so this is a thing that the 3 have in common.
Range:
You usually can see the whole range (all the possible y values) of your equation by looking at the graph or the data set. And obviously, if you have the equation you can easily find the range of it.

When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
Answer:
B. x
Step-by-step explanation:
-3x+8y=-6
3x-2y=-12
if we add these
-3x+3x+8y-2y=-6-12
6y=-12 so x will be eliminated
Final answer:
When solving a system by elimination, the variable eliminated is the one with coefficients that add up to zero when equations are combined.
Explanation:
When solving the following system by elimination, which variable would be eliminated after adding the 2 equations together?
When adding the two equations together in a system, the variable that will be eliminated will be the one that has coefficients with additive inverse values. For example, if one equation has x and the other has -x, adding them would result in the elimination of the x variable.
After adding the two equations together, look for a pair of variables that will cancel each other out, resulting in the elimination of one variable.

using the numbers 0-6 once, make 2 equivalent ratios
Step-by-step explanation:
As we have to use the number 0-6 once to make 2 equivalent ratios.
so lets solve the problem.
Determining first equivalent ratio
as
5 times 2 = 10and
32 times 2 = 64so
Together will get 10/64Therefore, first equivalent ratio
[tex]\:\frac{5}{32}=\frac{10}{64}[/tex]
Determining second equivalent ratio
[tex]\frac{13}{65}=\frac{4}{20}[/tex]
as
[tex]\frac{13}{65}=\frac{1}{5}[/tex]
and
[tex]\frac{4}{20}=\frac{1}{5}[/tex]
Therefore, second equivalent ratio
[tex]\frac{13}{65}=\frac{4}{20}[/tex]
Both can be simplified to 1:2.
To create two equivalent ratios using the numbers 0-6 once, we first need to understand that a ratio compares two quantities and equivalent ratios can be simplified or expanded from one another by the same factor. Here, we select the numbers carefully to form such ratios.
Let's use the numbers 2, 3, 4, and 6. The ratio of 2:4 is equivalent to 3:6 because when both sides of the first ratio are multiplied by 2, the result is the second ratio. Therefore, the ratios 2:4 and 3:6 are equivalent because they express the same relationship between numbers, as both can be simplified to the ratio of 1:2.

Ernesto's Gardening Service hauls wood chips in a pickup truck. The pickup truck has a
rectangular bed with an area of 35 square feet. Ernesto fills the truck bed to a height of 2
feet with wood chips. What is the volume of wood chips in the pickup truck?
Answer:
Volume of wood chips in the pickup truck is [tex]70[/tex] cubic units.
Step-by-step explanation:
Given that,
The pickup truck rectangular bed with an area of [tex]35[/tex] square feet.
Height of wood chips is [tex]2[/tex] feet.
From the question,
The shape formed by combination of rectangular bed and wood chips is a cuboid shape.
So, Volume of cuboid is [tex]= l\times b\times h[/tex] cubic unit.
Then, Volume of wood chips [tex]=Area\times height[/tex]
[tex]= 35 \times 2=70[/tex] cubic units.
Therefore, Volume of wood chips in the pickup truck is [tex]70[/tex] cubic units.
The volume of wood chips in Ernesto's pickup truck is calculated by multiplying the bed's area of 35 square feet by the height of 2 feet, resulting in a total volume of 70 cubic feet.
To determine the volume of wood chips that Ernesto's pickup truck can carry, we start with the given area of the rectangular bed, which is 35 square feet. Knowing the bed area and that Ernesto fills the bed to a height of 2 feet, we can calculate the volume by multiplying the area by the height.
Here is a step-by-step explanation:
Identify the area of the truck's bed: 35 square feet.
Identify the height to which the wood chips are filled: 2 feet.
Calculate the volume by multiplying the area by the height: Volume = area * height = 35 ft² * 2 ft.
Therefore, the volume of wood chips that the truck can carry is 70 cubic feet.

Just chose Bedroom 3 because it has whole numbers, none of the other rubbish.
The interior surface area of the bedroom can be calculated by the formula:
2lw + 2wh + 2lh
The surface area is 816 feet squared.
Since we are painting the room twice, we can just double this value for the sake of the next step.
The cost per gallon of paint is $33.98.
Each gallon covers 400 ft^2.
The number of gallons required is (816*2)/400, which is 4.08 gallons. If we approximate that we require 4 gallons, then the total cost will be $33.98*4 = $135.92.
