5/18 pounds per person.
he problem already says what to do, we need to divide because that's what Karen is doing, she is spliting or dividing the pounds of candy for 3 people. So, we just need to divide 5/6 by 3,
[tex]\frac{5}{6} \div 3 = \frac{5}{6} \times \frac{1}{3} =\frac{5}{18}[/tex]
5/18 per person.Which answer is it? A B C D
Answer:
answer:
I think the answer is B
Answer:
Hello!
Step-by-step explanation:
D is incorrect because the number in trees don't change, especially at a park.
C is incorrect because the identical beads can change.
B is incorrect because playing baseball doesn't really prove the constant rate of change.
The answer is A

joe buys groceries for his grandfather the groceries cost $42 plus 5% tax joe wants to know the total cost of the groceries including tax how much sales tax does joe pay on the groceries
its on iready
====================================================
Work Shown:
5% = 5/100 = 0.05
5% of 42 = 0.05*42 = 2.10
tax = $2.10
total cost including tax = $42 + $2.10 = $44.10
----------
An alternative is to multiply 42 by 1.05 to get
1.05*42 = 44.10
We get the same answer. The 1.05 refers to 1 + 0.05 where the "1" is 100% and the 0.05 is 5%, so the two combine to 105%, meaning the total cost is 105% of the cost before tax is considered.

What is an exponential function?An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.
For example, exponential functions can be used to calculate changes in population, loan interest charges, bacterial growth, radioactive decay or the spread of disease.
Given that,
The exponential function is given as, y = abˣ, we need to find the value of a and b,
When x = 0, ab⁰ = 4
a=4 (since, b⁰ = 1)
When x = 1, ab¹ = 2
4b = 2
b = 1/2
Hence, The values of a and b are a = 4 and b = 1/2

The volume of a cylinder is approximately 72ft3. Which is the best approximation of the volume of a cone with the same base and height as the cylinder?
Answer:
24 ft^3
Step-by-step explanation:
Cylinder:
Volume = (pi)r^2h
Cone:
Volume = (1/3)(pi)r^2h
When using r and h for both a cylinder and a cone, the only difference is the factor of 1/3 for the volume of the cone.
A cone with the same radius and height as a cylinder has 1/3 the volume of the cylinder.
volume of cylinder = 72 ft^3
volume of cone = (1/3) * 72 ft^3 = 24 ft^3
Answer:
The volume of cone is 24 ft³
Step-by-step explanation:
Given that volume of cylinder = 72 ft³
Volume of cylinder = πr²h
Volume of cone = [tex]\frac{1}{3}[/tex][tex]\pi[/tex]r²h
Volume of cone = volume of cylinder/3
= 72/3
= 24 ft³

What is the perimeter of this shape?
Answer:
87 feet
Step-by-step explanation:
Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:
30+9+12+9+9+9+9=87 feet
Hope this helps!
Answer:
The perimeter of this shape is 87 ft.
Step-by-step explanation:
Given that all side lengths are added together in order to find perimeter. So the perimeter is :
[tex]perimeter = 9 + 9 + 9 + 12 + 9 + 30 + 9[/tex]
[tex]perimeter = 45 + 30 + 12[/tex]
[tex]perimeter = 87 \: feet[/tex]
Need a bit of help with this question:
Firstly let's find hypotenuse(let it will be "n" of smaller triangle
Let use Pythagorean theorem
[tex]a^{2} + {b}^{2} = {n}^{2} \\ {20}^{2} + {10}^{2} = {n}^{2} \\ n = \sqrt{500} [/tex]
Now we need to find hypotenuse(x) of bigger triangle
[tex] {c}^{2} + {n}^{2} = {x}^{2} \\ {9}^{2} + { \sqrt{500} }^{2} = {x}^{2} \\ x = \sqrt{581} [/tex]
The value of x must be rounded to 1 DP, so
[tex] \sqrt{581} = 24.1039... \\ \sqrt{581} \simeq \: 24.1[/tex]

and drawing a 7, 8, or 9
1/3
3/8
C
1/9
d
1/12
Answer:
The required probability is option [tex]C)\ \dfrac{1}{9}[/tex]
Step-by-step explanation:
There are a total of 9 cards.
Total number of cases = 9
Let A be the event of choosing 1, 2 or 3.
Total number of favorable cases for event A = 3
Let B be the event of choosing 7, 8 or 9.
Total number of favorable cases for event B = 3
Formula for finding probability of an event E is:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
Finding P(A), using the formula:
[tex]P(A) = \dfrac{3}{9}\\\Rightarrow \dfrac{1}{3}[/tex]
Now, it is given that the card is replaced, so again total number of cases are 9.
For finding P(B), using the formula:
[tex]P(B) = \dfrac{3}{9}\\\Rightarrow \dfrac{1}{3}[/tex]
To find the probability that events A and B both happen, we can simply multiply P(A) and P(B) because these are independent events.
[tex]\text{Required probability = }P(A) \times P(B)\\\Rightarrow \dfrac{1}{3} \times \dfrac{1}{3} \\\dfrac{1}{9}[/tex]

Answer:
1 / (99 - 40x).
Step-by-step explanation:
The whole of g(x) is input to f(x), so:
we replace the x in f(x) by g(x).
f(g(x)) = 1 / [8(12 - 5x) + 3]
= 1 /( 96 - 40x + 3)
= 1 / (99 - 40x).

The solution is, g^36 power is equivalent to the expression (g-12)-3.
What is an exponent in math?An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.
here, we have,
given expression is,
g^(-12)(-3)
=g^(12*3)
=g^36
Hence, The solution is, g^36 power is equivalent to the expression (g-12)-3.

Do these side lengths make a right triangle? 3, 4, 5 *
Answer:
This is a right triangle
Step-by-step explanation:
We can check if this is a right triangle by using the Pythagorean theorem
a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse
3^2+4^2 = 5^2
9+16 = 25
25=25
This is true so it is a right triangle

What is the first step in solving the equation? 2(3k + 1) = 4k + 32
Answer:
The first step is to expand it to get rid of brackets .
Step-by-step explanation:
The first step, you have to eliminate brackets by expanding :
[tex]2(3k + 1) = 4k + 32[/tex]
[tex]2(3k) + 2(1) = 4k + 32[/tex]
[tex]6k + 2 = 4k + 32[/tex]
Next you have to collect like terms by making the same variable to one side and lastly, solve it :
[tex]6k - 4k = 32 - 2[/tex]
[tex]2k = 30[/tex]
[tex]k = 30 \div 2[/tex]
[tex]k = 15[/tex]
Answer:
Use the distributive Law on the left side of the equation.
Step-by-step explanation:
The first step is to distribute the 2 over the parentheses:
2(3k + 1) = 4k + 32 Distributing:
2*3k + 2*1 = 4k + 3
6k + 2 = 4k + 3
2k = 1
k = 1/2.
