Answer:

167.46

Step-by-step explanation:

V=\frac{1}{3} X  \pi r^{2} X h

\frac{1}{3} x  3.14 x 4^{2} x10

\frac{1}{3} X 50.24x 10

\frac{1}{3} x 502.4

V=167.46

On a fishing excursion, jeannie keeps 1/4 of the fish she catches and releases the remainder of the fish back into the lake. if
postnew [5]
To find 1/3 of 3/4 we divide the fraction by 3 which is equal to 1/4 or alternatively we can multiply the denominator by 3 which gives us 3/12 (1/4=3/12)
So 3/12 of the realesed fish are trout

To find 2/3 of 1/4 we need to first divide 1/4 by 3 which is equal to multiplying the denominator times 3 which gives us 1/12 and then we multiply by 2 which gives us 2/12
So 2/12 of the kept fish are trout

To find the total amount we add 2/12 and 3/12
3/12+2/12= 5/12

ANSWER:
5/12 of the fish she catches are trout

Does anyone know how to solve a system of linear equations using elimination? I am having a hard time on how to do it for differ
Mariana [72]
1. Multiply each equation so they end up with the same coefficient

2. Subtract your second equation from the first

3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)

4. Substitute the variable you found in the least step into one of the other equations and find a second variable.

5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))

I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)

Danielle earns a 7.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
sashaice [31]

Danielle earned $951.25

Step-by-step explanation:

Multiply her commission by her sales and add her base rate

x=7.25%($4500)+625 or x=0.0725(4500)+625

distribute

x=326.25+625

simplify

x=951.25

Draw a Hasse diagram of the partial order << of the set {2,3,4,6,8,9,10,12} where a << b iff b is divisible by a.
Ray Of Light [21]

Step-by-step explanation:

Consider the provided set {2,3,4,6,8,9,10,12}

Let the set is A.

A={(2 \prec 4), (2 \prec 6), (2 \prec 8), (2 \prec 10), (2 \prec 12), (3 \prec 6), (3 \prec 9), (4 \prec 8), (4 \prec 12), (6 \prec 12)}

Hence the required Hasse diagram is shown in figure 1:

In the Hasse diagram 2 and 3 are on the same level as they are not related.

The next numbers are 4, 6, 9, and 10. 4, 6 and 10 are divisible by both 2. 6 and 9 are divisible by 3. Then 8 and 12 are divisible by 4 also 12 is divisible by 6.

Hence, the required diagram of the partial order of the set {2,3,4,6,8,9,10,12} is shown in figure 1.

Which of the following recursive formulas represent the same arithmetic sequence as the explicit formula an=5+(n-1)2
sergey [27]

Answer:

Choice A:

a_1=5

a_{n}=a_{n-1}+2

Step-by-step explanation:

a_n=5+(n-1)2

means we looking for first term 5 and the sequence is going up by 2.

In general,

a_n=a_1+(n-1)d

means you have first term a_1 and the sequence has a common difference of d.

So it is between the first two choices.

The explicit form of an arithmetic sequence is: a_n=a_1+(n-1)d

An equivalent recursive form is a_n=a_{n-1}+d \text{ where } a_1 \text{ is the first term}

So d again here is 2.

So choice a is correct.

a_1=5

a_{n}=a_{n-1}+2
