Answer:
$1.2- 48 lbs
$.7- 32 lbs
Step-by-step explanation:
80(1)= 1.2(x) *.7(80-x)
80=1.2x+56-7x
24=.5 x
X= 48, this is the total for $1.20
Subtract 48 from 80 to get 32 lbs for $.70

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.
$225 grows 3.2% in an account. How much money is in the account after the growth? Express your answer to two decimal places.
Answers
Answer:
To find out how much money is in the account after the growth, we can use the formula:
FV = PV(1+r)
Where FV is the future value of the account, PV is the present value of the account, and r is the rate of growth expressed as a decimal.
In this case,
PV = $225
r = 3.2% = 0.032 (as a decimal)
By substituting the values in the formula:
FV = PV(1+r)
FV = $225 * (1 + 0.032)
FV = $225 * 1.032
FV ≈ $232.7 (rounded to two decimal places)
Therefore, the account has $232.7 after the growth of 3.2%.
Answer: $232.20
Step-by-step explanation:
3.2%=0.032
225x0.032=7.2
225+7.2=232.2

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

Mean is the AVERAGE.

Answers
Answer:
1 1/5.
Step-by-step explanation:
To divide a fraction by another fraction you have to change the equation like "Keep, Switch, Flip".
For the problem 24/25 ÷ 4/5,
You KEEP the first fraction as is, so 24/25
Then, you SWITCH the sign from division to multiplication.
Finally, you FLIP the second fraction upside down, (the reciprocal). So it's 5/4.
The equation is now 24/25 * 5/4, which we can just multiply the numerators and denominators. (or cross cancel first)
24 * 5 = 120
25 * 4 = 100
the fraction is 120/100. Simplified, it can be divided by 10 to make 12/10, and finally divided by 2 to make 6/5, or 1 1/5.
One triangle has a weight of 6 grams. What is the weight of one square?
Answers
Set up an equation for the left side and the right side.
Left side: 3 triangles x 6 = 18 + 4 squares
Right side: 4 triangles x 6 = 24 + 2 squares
Set them equal to each other :
18 + 4 squares = 24 + 2 squares
Subtract 18 from both sides:
4 squares = 6 + 2 squares
Subtract 2 squares from each side
2 squares = 6
Divide both sides by 2
1 square = 3 grams
The answer is 3 grams

\(\frac{64x^{3}-{1} }{4x-1}\)
Answers
\( \bf{= \frac{64 {x}^{3} - 1 }{4x - 1} }\\ \\ \bf{= \frac{( \cancel{4x - 1})(16 {x}^{2} + 4x + 1) }{ \cancel{4x - 1}}} \\\\ \bf{= 16 {x}^{2} + 4x + 1}\)
Answer:
\(16x^2+4x+1\)
Step-by-step explanation:
Given expression:
\(\dfrac{64x^3-1}{4x-1}\)
Step 1Factor the numerator of the given expression.
Rewrite 64 as 4³ and 1 as 1³:
\(\implies (4^3)x^3-1^3\)
\(\textsf{Apply the exponent rule} \quad a^b \cdot c^b=(ac)^b:\)
\(\implies (4x)^3-1^3\)
\(\textsf{Apply the Difference of Cubes Formula} \quad x^3-y^3=\left(x-y\right)\left(x^2+xy+y^2\right):\)
\(\implies (4x)^3-1^3=(4x-1)\left((4x)^2+4x(1)+(1)^2\right)\)
\(\implies (4x)^3-1^3=(4x-1)\left(16x^2+4x+1\right)\)
Step 2Replace the numerator in the given expression with the factored numerator from step 1:
\(\implies \dfrac{64x^3-1}{4x-1}=\dfrac{(4x-1)\left(16x^2+4x+1\right)}{4x-1}\)
Cancel the common factor (4x - 1):
\(\implies 16x^2+4x+1\)
