Answer: 2144.7 cm^3
Step-by-step explanation: You need to find the volume of a sphere with a radius of 8 cm if you want to know how much water Jack can hold.
V = 4/3 π r^3 = 4/3 * π * 8^3 ≈ 2144.7 cm^3
Answer:
Step-by-step explanation:
Let d be the number of days.
We have been that each day Katie finds 12 more seashells on beach, so after collecting shells for d days Katie will have 12d shells.
We are also told that Katie already has 34 seashells in her collection, so total number of shells in Katie collection after d days will be:
As Katie wants to collect over 100 seashells, so the total number of shells collected in d days will be greater than 100. We can represent this information in an inequality as:
Therefore, the inequality can be used to find the number of days, d, it will take Katie to collect over 100 seashells.
In order to find out when Katie will have over 100 seashells, we use the equation 34 + 12d > 100. After simplifying, the inequality is d > 5.5. So, it will take Katie over 5.5 days to collect over 100 shells.
The question states that Katie already has 34 seashells and finds 12 more each day. This can be represented by the equation 34 + 12d, where d represents the number of days. In order to find out when Katie will have more than 100 seashells, we need to set this equation greater than 100 and solve for d.
So, 34 + 12d > 100. If we subtract 34 from both sides, we get 12d > 66. Then, divide both sides by 12 to solve for d. d > 66/12. The value of d in this case turns out to be approximately 5.5.
This means it will take Katie slightly over 5.5 days to collect over 100 seashells, given that she can use fractions of days to find seashells.

Y=2x+3
Answer: y=13
Step-by-step explanation:
y=13
Step-by-step explanation:
given that,
x=5
to find,
y=2x+3, when x=5
substitute 5 in the place of "x" we get,
y=2×5+3
according to BODMAS rule( bracket of division multiplication addition and subtraction) first we have to multiply 5 with 2 and then add the product with 3 we get,
y=10+3
y=13
To solve the equation, subtract 10 from both sides and divide by 2 to find the value of x.
To solve this problem, we need to set up an equation using the given information. Let's assume the number is x. We can translate the phrase 'twice a number' into the expression 2x. The equation becomes:
2x + 10 = 36
Next, we can solve for x by subtracting 10 from both sides:
2x = 26
Finally, we divide both sides by 2 to isolate x:
x = 13

Answer:
y=3
Step-by-step explanation:
12(y+6)=36y
12y+72=36y
72=24y
y=3
Hope this helps! :)
Answer:
To find the value of y that makes the equation 12(y+6)=36y true, we need to solve for y. Let's break down the steps:
1. Distribute the 12 to both terms inside the parentheses:
12y + 72 = 36y
2. Next, we want to isolate the variable y. To do this, we'll move the 12y term to the other side of the equation by subtracting 12y from both sides:
72 = 24y
3. Now we have 24y on one side. To solve for y, we divide both sides of the equation by 24:
72/24 = y
4. Simplifying the left side gives us:
3 = y
Therefore, the value of y that makes the equation true is y = 3.

Answer: the first term is 5
Step-by-step explanation:
In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as
Sn = (ar^n - 1)/(r - 1)
Where
n represents the number of term in the sequence.
a represents the first term in the sequence.
r represents the common ratio.
From the information given,
S12 = 20475
r = 2
n = 12
Therefore,
20475 = (a × 2^(12) - 1)/2 - 1
20475 = (a × 4095)
20475 = 4095a
a = 20475/4095
a = 5
