Coach Posey has $10,000 to invest. He can go to Bryant Bank that pays 5% simple interest or Hornets Bank that pays 4% interest c

Zinaida [17]

Here's what we know: Coach Posey has $10,000, and will be hypothetically investing in Bryant Bank for 12 years at 5% simple interest.

We can calculate the interest with the formula I = prt, where I is the interest, p is the principal (starting amount), r is the rate, and t is the amount of time.

I = $10,000(0.05)(12)
I = $10,000(0.6)
I = $6,000

He started with $10,000, and earned $6,000 interest, so he has $10,000 + $6,000, or $16,000.

Write 5(6x+4)-2(5x-2) in the form a(bx+c) where a,b and c integers and a>1

Pavel [41]

Answer:

4(5x + 6)

Step-by-step explanation:

To start, let's expand things out, as we cannot learn anything from this form. We get 30x + 20 - 10x + 4, or 20x + 24. To find the GCD (Greatest Common Divisor), we take the terms and try to find the number (or term) that divides them. It must be a constant, because of the 24, and 4 goes into 20 and 24. So, our final answer is 4(5x + 6).

The density of gold is about 20 g/ cm^3 . The density of sand can be estimated at 2.5 g/cm^3. The gold statue can be modeled as

pantera1 [17]

Answer:

The mass of the bag of sand must be equal to $m=12,000\pi\ g$

Step-by-step explanation:

<u><em>The complete question is</em></u>

In the opening scene of the movie Raiders of the Lost Ark, Indiana Jones replaces a golden statue with a bag of sand. The platform on which the statue is placed is designed to detect the mass of the statue. If the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues.

The density of gold is about 20 g/ cm^3 . The density of sand can be estimated at 2.5 g/cm^3. The gold statue can be modeled as a cylinder with height 25 cm and radius 8 cm.

In terms of pi, what is the mass of sand Indiana Jones needs to avoid triggering the mechanism?

step 1

Find the volume of the gold statue

The volume of a cylinder is equal to

$V=\pi r^{2}h$

substitute the given values

$V=\pi (8)^{2}(25)$

$V=600\pi\ cm^3$

step 2

Find the mass of gold

Remember that the mass is equal to multiply the density by the volume

$m=(20)600\pi\\m=12,000\pi\ g$

step 3

what is the mass of sand Indiana Jones needs to avoid triggering the mechanism?

we know that

The mass of the bah of sand must be equal to the mass of the statue

therefore

The mass of the bag of sand must be equal to

$m=12,000\pi\ g$

The sum of the roots of 8x^2- 2x

Andrews [41]

Answer:

1/4

Step-by-step explanation:

To find the roots of the expression, factor the expression by GCF.

$8x^2 - 2x\\2x(4x-1)$

The roots are the factors set equal to 0 and solved for x.

2x = 0

x=0

4x-1 = 0

x = 1/4

The sum is the addition of the two roots 0 + 1/4 = 1/4
