Answer:

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Step-by-step explanation:

Formula for the simple interest is,

Interest = [tex]\frac{P\times r\times t}{100}[/tex]

Here, P = Principal amount

r = rate of interest  

t = Duration of investment

Let Phyllis invested amount (at 5.25% rate of interest) = $x

Therefore, Interest on this amount,

Interest = [tex]\frac{5.25\times x}{100}[/tex]

             = $0.0525x

If he invested the rest amount $(13000 - x) at the rate of 5%,

Interest earned on this amount = [tex]\frac{(13000-x)\times 5\times 1}{100}[/tex]

                                                    = $(650 - 0.05x)

Interest earned on total amount = $672

Therefore, $0.0525x + $(650 - 0.05x) = $672.5

0.0025x + 650 = 672.5

0.0025x = 22.5

x = $9000

Rest amount = 13000 - 9000

                     = $4000

Phyllis invested $9000 at the rate of 5.25% and $4000 at the rate of 5%.

Answer:

100th term = 962

Step-by-step explanation:

You need  to find the first term of the sequence

The formula to use is

[tex]a_{n} = a_{1} + (n - 1)d[/tex]    In your problem, n = 14.  So,

[tex]102 = a_{1} + (14 - 1)10\\102 = a_{1} + 130\\a_{1} = -28\\\\[/tex]

Now you can find the 100th term.  n = 100, first term = -28 and d = 10

[tex]a_{100} = -28 + (100 - 1)10\\ = -28 + 990\\ = 962[/tex]

100th term = 962

According to order of operations, multiplication comes before addition.

4(– 7) + 8 =

-28 + 8 =

-20

An expression equivalent to 4(– 7) + 8 would be:

8 + 4(-7)

This is true because of the commutative property which states that a+b=b+a

Answer:

-20

Step-by-step explanation:

It is very simple!

There are 60 students in the Environmental club.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

There are 240 students in the seventh grade,

and 25% are in the Environmental Club.

That means,

students are in the Environmental Club,

= 240 x 25/100

= 60

Answer:

4

Step-by-step explanation:

We are asked to find a slope whilst given a graph.

To solve for slope, we must pick two coordinate points that are not decimals and following the formula of rise over run, which in basic terms y over x.

So based on what I see, I can see (1, 1) and (2, 5).

The rise over run is as followed :

[tex]\frac{y2 - y1}{x2 - x1}[/tex]

2 and 1 meaning the first and second number within the coordinate, so substitute :

[tex]\frac{5 - 1}{2 - 1}[/tex]

[tex]\frac{4}{1}[/tex]

Divide :

[tex]4[/tex]

4 is our slope.

Answer: D. x=72

Step-by-step explanation:

With the equation x/8-6=3  we can start solving by first moving the "-6"

                 x/8-6(+6)=3(+6)

                 x/8=9             <-- Rewrite equation after adding "6" to both sides

                 x/8(*8)=9(*8)  <--- Multiply both sides by 8

                 x=72              <-- After multiplying, solution is found
