a cone and a sphere have the same volume. the height of the cone is 96 units. what would be the values for the radius of the cone and the sphere?
Answer:
The radius = 24 units.
Step-by-step explanation:
I am assuming that the 2 radii are equal then:
1/3 pi r^2 * 96 = 4/3 pi r^3
then:
4/3 pi r^3 / 32 pi r^2 = 1
4/3r^3 / 32 r^2 = 1
4/3 r * 1/ 32 = 1
r = 32 * 3/4
= 24.
which expressions are equivalent to -90 - 60w
A : -30(3+2w)
B : (-9-6w) ⋅ 10
C : -3(30 - 20w)
D : (6 + 4w)×15
E : −20(4.5 + 3w)
Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Step-by-step explanation:
Using distributive property:
A : -30(3+2w) = -90 - 60w : equivalent to -90 - 60w
B : (-9-6w) ⋅ 10 = -90 - 60w : equivalent to -90 - 60w
C : -3(30 - 20w) = -90 + 60w : NOT equivalent to -90 - 60w
D : (6 + 4w)×15 = 90 + 60w : NOT equivalent to -90 - 60w
E : −20(4.5 + 3w) = - 90 - 60w : equivalent to -90 - 60w
Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Answer:
A, B and E.
Step-by-step explanation:
We have -90-60w. Both 90 and 60 are multiples of 30, so we can apply common factor -30:
-90-60w = -30(3+2w). Then option A is correct.
Now, 90 and 60 are also multiples of 10, so we can apply common factor 10:
-90-60w = 10(-9-6w). Then option B is correct.
Now, 90 and 60 are also multiples of 3, so we can apply common factor -3:
-90-60w = -3(30+20w). Then option C is incorrect.
Now, 90 and 60 are also multiples of 15, so we can apply common factor 15:
-90-60w = 15(-6-4w). Then option D is incorrect.
Now, 90 is not a multiple of 20 but we can apply common factor obtainig a decimal number. Applying common factor -20 we have
-90-60w = -20(4.5+3w). Then option E is correct.

Use the graph to write the factorization of x^2+4x-5
Answer: OPTION C
Step-by-step explanation:
By definition, the roots of the quadratic function are the interceptions of the parabol with the x-axis.
As you can see in the graph, the parabola intersects the x-axis at:
[tex]x=-5\\x=1[/tex]
Then these are the roots.
Therefore, this means that:
[tex]x=-5\\x+5=0\\\\x=1\\x-1=0[/tex]
So, the factorization is the following:
[tex](x+5)(x-1)=0[/tex]
ANSWER
[tex]y = (x + 5)(x - 1)[/tex]
EXPLANATION
From the graph, the x-intercepts are
[tex]x = 1[/tex]
and
[tex]x = - 5[/tex]
This implies that (x-1) and (x+5) are factors of the function represented by the graph.
Therefore we factor the function as
[tex]y = (x + 5)(x - 1)[/tex]

ason buys a pizza for $\$15.59$. He also buys $6$ sodas. Each soda costs the same amount. He spends $\$23.33$ on the pizza and the sodas.
Jason finds the cost of each soda by calculating $(23.33\ -\ 15.59)\ \div\ 6$. Tim finds the cost of each soda by solving the equation $15.59\ +\ 6c\ =\ 23.33$, where $c$ is the cost of each soda.
Which approach uses the sequence of operations necessary to find the cost of each soda: Jason’s, Tim’s, both, or neither? Explain why.
Answer:
Both because they're basically the same thing ;-;
Step-by-step explanation:
1) 23.33 - 15.59 = 7.29
7.74/6 = 1.29 So he bought 1 soda ;-;
2) 15.59 + 6c = 23.33 - Subtract 15.59 from both sides:
6c = 7.74 - Divide both sides by 6
c = 1.29 So he bought 1 soda again
The rest of the money is probably the tax so ;-;
Good luck and hopefully I helped!

Help me with this question
Answer:
A
Step-by-step explanation:
This is an even polynomial because both ends end up. This means the degree of the polynomial is even. This means b and c are not solutions since their degrees are odd.
To determine between A and D look at the x-intercepts. The x-intercepts of a polynomial graph have a special relationship with its equation. The x-intercepts are the solutions or roots of the factors. This means that when each factor is set equal to 0 and solved, its solution is an x-intercept. Here the x-intercepts are x = -1, 0,3. This means the factors are x(x+1)(x-3).
Notice at x = -1, the function touches but does not cross? This means the factor has an even exponent on it.
So the expression is likely x(x+1)^2 (x-3).
Since only one factor has an exponent, the answer is A.
A cake recipe calls for 425 grams of flour about how many pounds of flour do you need? use the conversion factors
1 ounce 1 pound
————- and —————
28.4 grams 16 ounces
To convert 425 grams of flour to pounds, you can set up a proportion and solve for X. The answer is approximately 1.898 pounds.
Explanation:To convert grams to pounds, we can use the conversion factor:
1 ounce 1 pound
————- and —————
28.4 grams 16 ounces
To convert 425 grams of flour to pounds, we can set up a proportion:
X pounds 425 grams
16 ounces 28.4 grams
To solve for X, we can cross-multiply and then divide:
X pounds = (425 grams x 16 ounces) / 28.4 grams
Calculating this, we find that X = 1.8978 pounds of flour.

Answer:
First choice: m = -4
Step-by-step explanation:
The second equation is already solved for n, so lets's use the substitution method and substitute m - 2 for n in the first equation.
m - 2n = 8
m - 2(m - 2) = 8
m - 2m + 4 = 8
-m + 4 = 8
-m = 4
m = -4
The second equation tells you what 'n' is. It's "m-2" .
So you can simply write "m-2" in place of 'n' in the first equation.
Then the first equation says [ m - 2(m-2) = 8 ], and you should have no trouble solving that.

Find the area of the shaded sector. Leave your answer in terms of pi.
Answer options:
18pi ft2
24pi ft2
32pi ft2
3pi ft2
Answer:
18π ft^2
Step-by-step explanation:
Area of Sector = [tex]\frac{\theta}{360}*\pi r^2[/tex]
Where
[tex]\theta[/tex] is the angle of the sector (in our case it is 45°), and
r is the radius (which is 12 ft)
So we plug these into the formula and get our answer to be:
[tex]A=\frac{\theta}{360}*\pi r^2\\A=\frac{45}{360}*\pi (12)^2\\A=\frac{1}{8}\pi*144\\A=18\pi[/tex]
This is our answer: 18π
Answer:
= 18 ft²
Step-by-step explanation:
The area of a sector is given by the formula;
Area = θ/360 × πr² ; where θ is the angle subtended by the arc to the center, r is the radius.
Therefore;
Area = 45/360 × π ×12²
= 18 ft²
Your gross income is $4,520.00/month. Your deductions are FICA (7.65%), federal tax withholding (11.75%), and state tax withholding (8.5%). Your fixed expenses are 30% of your realized income. You saved 5 months' worth in an emergency fund, placing 75% in a 60-day CD at a 5.25% APR and the rest in a regular savings account at a 3.8% APR. What is the total amount of your emergency fund? How much is in the CD and savings account? How much is the total interest earned between both accounts in 60 days?
The emergency fund total amount is [tex]$\boxed{\$11,413.78}$[/tex]. The amount in CD is [tex]$\boxed{\$8,557.334}$[/tex]. The amount in savings account: [tex]$\boxed{\$2,853.445}$[/tex]. Total interest earned: [tex]$\boxed{\$94.896695}$[/tex].
To solve this problem, we will follow these steps:
1. Calculate the total deductions from the gross income.
2. Determine the realized income after deductions.
3. Calculate the fixed expenses based on the realized income.
4. Compute the amount saved in the emergency fund.
5. Divide the emergency fund into the portions for the CD and the savings account.
6. Calculate the interest earned on both the CD and the savings account over 60 days.
7. Sum the interest earned from both accounts to find the total interest.
Let's begin:
1. Calculate Total Deductions:
Gross income = $4,520.00/month
FICA = 7.65% of gross income
Federal tax withholding = 11.75% of gross income
State tax withholding = 8.5% of gross income
Total deductions = FICA + Federal tax withholding + State tax withholding
Total deductions = 0.0765 × $4,520 + 0.1175 × $4,520 + 0.085 × $4,520
2. Determine Realized Income:
Realized income = Gross income - Total deductions
3. Calculate Fixed Expenses:
Fixed expenses = 30% of realized income
4. Compute the Amount Saved in the Emergency Fund:
Emergency fund = 5 months' worth of realized income after fixed expenses
Emergency fund = 5 × (Realized income - Fixed expenses)
5. Divide the Emergency Fund:
75% in a CD and 25% in a savings account
CD amount = 0.75 × Emergency fund
Savings account amount = 0.25 × Emergency fund
6. Calculate Interest Earned:
Interest on CD = CD amount × (5.25% APR / 12) × (60 / 30)
Interest on savings = Savings account amount × (3.8% APR / 12) × (60 / 30)
7. Calculate Total Interest Earned:
Total interest = Interest on CD + Interest on savings
Now, let's perform the calculations:
1. Total deductions = 0.0765 × $4,520 + 0.1175 × $4,520 + 0.085 × $4,520
Total deductions = $344.28 + $530.44 + $384.20
Total deductions = $1,258.92
2. Realized income = $4,520 - $1,258.92
Realized income = $3,261.08
3. Fixed expenses = 0.30 × $3,261.08
Fixed expenses = $978.324
4. Emergency fund = 5 × ($3,261.08 - $978.324)
Emergency fund = 5 × $2,282.756
Emergency fund = $11,413.78
5. CD amount = 0.75 × $11,413.78
CD amount = $8,557.334
Savings account amount = 0.25 × $11,413.78
Savings account amount = $2,853.445
6. Interest on CD = $8,557.334 × (0.0525 / 12) × 2
Interest on CD = $8,557.334 × 0.004375 × 2
Interest on CD = $76.640625
Interest on savings = $2,853.445 × (0.038 / 12) × 2
Interest on savings = $2,853.445 × 0.0031667 × 2
Interest on savings = $18.25607
7. Total interest = $76.640625 + $18.25607
Total interest = $94.896695

Each sheet cake requires 3 cups of flour and 2 cups of sugar. If a bakery has 75 cups of flour and 75 cups of sugar, how many sheet cakes can be made? Enter the number in the box.
Answer:
25
Step-by-step explanation:
Since we have the same amount of each ingredient, the first step is to find out what will be the limiting ingredient (of which we need more quantity per cake) that ingredient is flour.
So the cakes we can make with 75 cups of flour will be the total cakes we can make.
since we need 3 cups of flour per cake:
[tex]\frac{75 cups}{3cups/cake} =25 cakes[/tex]
we can make 25 cakes in total.
*sugar will be left over but because with 25 cakes the flour ends, this is the total amount of cakes we can make,
