Answer: 72.9 in^3
Step-by-step explanation:
The softball is a sphere, and we know that the volume of a sphere is:
V = (4/3)*pi*r^3
where pi = 3.14 and r is the radius.
We also know that the radius is half the diameter, and the diameter is 5.2 in
r = 5.2in/2 = 2.6in
Then the volume is:
V = (4/3)*pi*(2.6in)^3 = 72.9 in^3
The correct answer is 73.6 in^3
How is the graph of log (x – 2) + 1 translated from the graph of log x?
Answer:
See the two translations described below
Step-by-step explanation:
Start with the graph of y = log x. This graph passes through (1, 0) and exists only for x > 0. The line x = 0 is its vertical asymptote.
Translating this graph 2 units to the right results in h(x) = log (x - 2).
Translating the graph of h(x) = log (x - 2) upward by 1 unit results in the graph of log (x – 2) + 1.
Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 18% each week. The following function represents the weekly weed growth: f(x) = 86(1.18)x. Rewrite the function to show how quickly the weeds grow each day. f(x) = 86(1.02)x; grows approximately at a rate of 0.2% daily f(x) = 86(1.18)7x; grows approximately at a rate of 1.8% daily f(x) = 86(1.02)7x; grows approximately at a rate of 2% daily f(x) = 86(1.187)x; grows approximately at a rate of 0.18% daily
Answer:
A.f(x) = 86(1.04)x; grows approximately at a rate of 0.4% daily

Step-by-step explanation:
Write an expression for the situation described. Each person's share if 'p' people share 8 slices of pizza equally.
Answer:
The expression that represent each person's share is: [tex]y(p) = \frac{8}{p}[/tex]
Step-by-step explanation:
To divide a pizza, or anything else, equally among a certain number of people, we need to divide the total of pizza available by the number of people who will eat the pizza. In this case there are 8 slices and 'p' people, therefore:
[tex]y(p) = \frac{8}{p}[/tex]
In order to validate the expression, we can see that if 8 people eat the pizza, each gets one slice, because 8 divided by 8 is 1, while if 4 people eat the pizza each get 2 and so on.
The expression that represent each person's share is: [tex]y(p) = \frac{8}{p}[/tex]

Answer:
x + x+12 + 3(x+12) = 123
x = 15
Step-by-step explanation:
Jamil : x
Kiera : x+12
Luther : 3 ( x+12)
x + x+12 + 3(x+12) = 123
Distribute
x + x+12 + 3x+36 = 123
Combine like terms
5x+ 48 = 123
Subtract 48 from each side
5x+48-48 = 123-48
5x =75
Divide by 5
5x/5 = 75/5
x = 15
Answer:
Equation:
123 = x + 12 + x + 3(12 + x)
Solution:
x = 15
Step-by-step explanation:
Jamil: x
Kiera: 12 + x
Luther: 3(12 + x)
Total: 123 badges
Equation:
123 = x + 12 + x + 3(12 + x)
Solve:
123 = x + 12 + x + 3(12 + x)
123 = x + 12 + x + 36 + 3x
123 = 5x + 48
-48 -48
75 = 5x
/5 /5
15 = x
Therefore, the value of x is 15.

URGENT: At what annual rate of simple interest must $12,000 be invested to earn $135 in interest each quarter? (I will give brainliest)
Answer:
4.5%
Step-by-step explanation:
Firstly we should understand that a quarter is every three months.
So if $135 is earned each quarter, then 4 * 135 = $540 is earned per annnum
We use the simple interest formula to get the rate.
Mathematically;
I = PRT/100
where P is the amount deposited = 12,000
R is what we are looking for which is the rate
T is the time which is 1 year
I is the interest which is 540
We can rewrite the simple interest formula to be:
100I = PRT
R = 100I/PT
Thus substituting the values we have;
R = (100 * 540)/(12,000 * 1) = 4.5%
Answer:
4.5%Step-by-step explanation:
Using the simple interest formula to tackle this question.
[tex]SI = \frac{PRT}{100}[/tex]
P = principal = $12,000
R = rate (in %) = ?
T = Time(in years) = 1/4 years
135 = [tex]\frac{12000*R}{100*4}[/tex]
[tex]135 = \frac{12000R}{400}\\ 54000 = 12000R\\R = \frac{54000}{12000}\\ R = 4.5\ %[/tex]
The annual rate of simple interest is 4.5%

You bought a magazine for $3 and two notepads. You spent a total of $13. How much did each notepad cost? *
Answer:
$5
Step-by-step explanation:
We want to find the cost of a notepad considering a magazine costs $3 and we buy 2 notepads and the total cost of the magazine and the 2 notepads is $13 so we can set up an equation to represent this situation. Let 'n' be notepads and that's the value we are solving for so,
⇒ Form the equation
→ 2n + 3 = 13
⇒ Minus 3 from both sides to isolate 2n
→ 2n = 10
⇒ Divide both sides by 2 to find the cost of one notepad
→ n = 5
The cost of one notepad is $5 considering that a magazine cost's $3 and two notepads and total is $13.

plz help me how would you solve 4x + 2y = 18, 3x - 5y =20 by elemination
Answer: x = 5, y = -1
Step-by-step explanation:
Equation 1: 4x + 2y = 18
Equation 2: 3x - 5y = 20
In order to eliminate one of the variables , find the LCM of either x or y.
I chose to eliminate y. The LCM of 2 & 5 is 10.
Multiply the entire equation so the coefficient of the variable equals the LCM.
Then add the equations and solve for the remaining variable.
5(4x + 2y = 18) --> 20x + 10y = 90
2(3x - 5y = 20) --> 6x - 10y = 40
26x = 130
÷26 ÷26
x = 5
Next, input x = 5 into either of the equations to solve for y.
Equation 1: 4x + 2y = 18
4(5) + 2y = 18
20 + 2y = 18
-20 -20
2y = -2
÷2 ÷2
y = -1

Answer:
6/15 * 2/14 = 12/210
Step-by-step explanation:
This is compound probability. To calculate compound probability, you need to multiply the probabilities of each event happening together.
In this example, the events are selecting a pineapple cake, then a strawberry cake.
Let's find the probabilities!
There are 2 strawberry cakes, 6 pineapple cakes, and 7 chocolate cakes. This means that he has 15 cakes in total.
Therefore, the probability of selecting a pineapple cake is 6/15.
Now, if we assume that he has selected a pineapple cake already, there are now 14 cakes.
Next, the probability of selecting a strawberry cake is now 2/14. This is because he already took a pineapple cake, and now he has to pick a strawberry cake out of the remaining 14 cakes.
Multiply these two probabilities to find the compound probability: 12/210 ( this could be further simplified, but that's how they give it to you! )
Hope this helps! Please feel free to contact me if you have any further questions :)

What is corresponding angles ?the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal
According to the question,
Given the diagram we have to find the angles which are corresponding angles with ∠12.
Those angles which are on the same side of traversal called corresponding angles.
By definition of corresponding angles the angles which are corresponding to ∠12 are ∠8 and ∠16. These angles lie on same side of traversal line.

The true statement about the degree of the sum and difference of the polynomials 3x⁵y - 2x³y⁴-7xy³ and -8x⁵y +2x³y⁴ + xy³ is "the sum has a degree of 6, but the difference has a degree of 7."
What is a polynomial?An expression that consists of variables, constants, and exponents that is combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a polynomial.
Given:
There are two polynomials,
3x⁵y - 2x³y⁴-7xy³ and -8x⁵y +2x³y⁴ + xy³.
The sum of the polynomials,
= 3x⁵y - 2x³y⁴-7xy³ -8x⁵y +2x³y⁴ + xy³.
= 5x⁵y -6xy³.
And the degree is 6.
The difference of the polynomials,
= 3x⁵y - 2x³y⁴-7xy³ + 8x⁵y - 2x³y⁴ - xy³.
= 13x⁵y - 4x³y⁴-8xy³.
And the degree is 7.

What are the foci of the hyperbola represented by the equation (x^2)/64 - (y^2)/32 =1
Answer:
x = √2y^2 + 64 or x = √2y^2 + 64
Step-by-step explanation:
Solve for x.
x^2/64 - y^2/32 = 1
Step 1: Add 1/32 y^2 to both sides.
1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2
Step 2: Divide both sides by 1/64.
1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64
x^2 = 2y^2 + 64
Step 3:
x = √2y^2 + 64 or x = √2y^2 + 64
Answer:
x = √2y^2 + 64
Step-by-step explanation:
= 1/64 x^2 + -1/32 y^2 + 1/32 y^2 = 1 + 1/32 y^2
= 1/64 x^2/ 1/64 = 1/32 y^2 + 1/ 1/64
= x^2 = 2y^2 + 64
= x = √2y^2 + 64
