Answer:

At 5% amount invested = $7,500

At 7% amount invested = $3,500

Step-by-step explanation:

We shall create an equation for this.

Let the amount invested with 5 % interest = "x"

Then remaining amount = 11,000 - x, Since total amount invested = $11,000

(x \times 5%) + ((11,000-x) \times 7%) = $620

0.05 x + 770 - 0.07 x = 620

770 - 620 = 0.07 x - 0.05 x

150 = 0.02 x

\frac{150}{0.02} = x

$7,500 = x

Therefore, amount invested at 5% = $7,500

At 7% = $11,000 - $7,500 = $3,500

A pyramid has a base area of 124 in² and a height of 25.2 in. What is the volume of the pyramid?
xeze [42]

Answer:

1041.6

Step-by-step explanation:

The volume of a pyramid is V=b x h x 1/3 . b is the area of the base and h is the height. V=124 x 25.2 x 1/3 This can simplify to V=3124.8 x 1/3 . You could also just divide by 3. You will get 1041.6

What is the area of a semi circle that has a diameter of 1 1/2?
SVEN [57.7K]

Answer:

A=0.8836

Step-by-step explanation:

Area of circle:

\pi r^2

By using the area of a circle, we can get the area of a semicircle:

\frac{\pi r^2}{2}

Let's convert the mixed fraction to an improper fraction and then a decimal:

1\frac{1}{2} = \frac{3}{2} = 1.5

Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:

\frac{1.5}{2} =0.75

Now we have the radius, so we can plug in our values and find the area:

\frac{\pi0.75^2}{2} = 0.88357293

A=0.88357293
