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:

Because they are both negative that means they are on the left side so -0.4 is closer to the 0 so less.

Answer:

69.08m

Step-by-step explanation:

Circumference of a circle = πd where

d is the diameter of the circle

Given

diameter = 22metres

circumference of the circle = 3.14(22)

circumference of the circle  = 69.08m

Hence the circumference of the circle is 69.08m

Answer:

9) 5/10

10) 4/5

Step-by-step explanation:

A terminating decimal is a decimal that stops eventually

2/3 = 0.6666666...

5/6 = 0.833333...

5/10 = 0.5

6/9 = 0.6666666...

5/10 has a result of a terminating decimal

8/9 = 0.888888...

1/7 = 0.142857...

4/5 = 0.8

4/11 = 0.36363636....

Answer:

[tex]x < - 21[/tex]

Step-by-step explanation:

1. Multiply both sides by 3.

[tex]x < - 7 \times 3[/tex]

2. Simplify 3 × 7 to 21.

[tex]x < - 21[/tex]

therefor, the answer is x < -21

Answer:

Step-by-step explanation:

For a function to have an inverse, it has to pass the horizontal and vertical line test, yes both of them. This function does, so we can continue. The first step for finding an inverse is replacing f(x) with y. Then switch the places of x and y.

[tex]x=\sqrt{y-1}[/tex]

Now the next step is to solve for this new y value, which is equivalent to f^-1(x). Square both sides to get rid of the radical.

[tex]x^2=y-1[/tex]

Add 1 to both sides and that is your inverse function

[tex]y=x^2+1[/tex]

Answer:

(-4,1)

Step-by-step explanation:

The answer is just where the two lines intersect

I'm rather tired so double check me on this but I'm getting about (-4,1) and it's asking for an approximation so think (-4,1) is fine

Answer:

It's around (-4. 5, 1.5). It's somewhere in that range.

Answer:

[tex]-452 \frac{6}{7}[/tex]

Step-by-step explanation:

You just subtract the new elevation from the original, [tex]-355 \frac{2}{7} - 97 \frac{4}{7} = -452 \frac{6}{7}[/tex]

Answer:

3

Step-by-step explanation:

To find the average rate of change, we can use the formula: (y2-y1) / (x2-x1).

Let (15, 45) be (x1, y1) and (29, 87) be (x2, y2).

So we have: (87-45) / (29-15)

This can be simplified to: 42/14, or 3.

Actually Welcome to the Concept of the Surface areas and Volume.

Since Box A is cube, it's volume is Side^3

hence taking the cube root of 512 , we get as,

Side length of Box A is 8 m.

hence diving 8/2 = 4 m

4 m is a side of Box B.

hence, Volume of Box B is = (4)^3 = 64 cubic metres.

Vol. Box B = 64 m^3

Answer:

The correct answer is D: 64 meters cubed

Step-by-step explanation:

You can take any example but let's say 128 times 2 times 2 which equals box A, now you must divide all dimensions by 2 and you will get 64 times 1 times 1 which adds up to 64, this will work with any example.

Answer:

x=37, Angle A is 74. Exterior angle B is 185

Step-by-step explanation:

I'm pretty sure this right but This is a triangle that is folded to the inside. This means that most likely there is a negative interior degree

angle. Using the interior theorem, we can add up all the non adjacent sides to find the exterior angle of the adjacent side. 79+2x+32=5x, 2x+111=5x, 111=3x, x=37. Then plug 37 in for x Angle A is 74 degree and B exterior angle Is 185 degree.

Answer:

y = 2

Step-by-step explanation:

m = (2 - 2)/(6 - (-6))

m = 0

there's no slope, so it's just 2

As you can see the 2 points have the same y coordinate that means the line passing through it is going to be a horizontal line with a consistent y level of -2.

The equation will be just what I said y=2

Hope this helped!
