Scott invested a total of $5900 at two separate banks. One bank pays simple interest of 12% per year while the other pays simple interest at a rate of 6% per year. If
Scott earned $540.00 in interest during a single year, how much did he have on deposit in each bank?
Scott had $ 2,800 on deposit at the bank that payed 12% interest.

Answers

Answer:

$3100 at 12%$2800 at 6%

Step-by-step explanation:

Let x represent the amount on deposit at 12%. Then 5900-x is the amount deposited at 6%, and the total interest earned is ...

  12%·x +6%·(5900 -x) = 540

  0.06x + 354 = 540 . . . . . . . . eliminate parentheses

  0.06x = 186 . . . . . . . . . . . . . . subtract 354

  x = 3100 . . . . . . . . . . . . . . . . . divide by 0.06

Scott invested $3100 at 12% and $2800 at 6%.

_____

Quick sanity check

The average interest earned is $540/$5900 ≈ 0.0915 ≈ 9.15%. This is more than the average of 12% and 6%, which is (12+6)/2 = 9 percent. Hence more than half of the money must be deposited at 12%.

A town’s population of children increased from 376 to 421 during the past year.
Which equation shows how to find the percent increase?
A. p=421−376
376
B. p=421−376
421
C. p=376
421−376
D. p=376+421
376

Answers

The equation shows how to find the percent increase:

[tex]Percent\ increase = \frac{421-376}{376} \times 100[/tex]

Solution:

Given that,

A town’s population of children increased from 376 to 421 during the past year

To find: percent increase

The percent increase is given by formula:

[tex]\text{Percent increase} = \frac{\text{Final value - initial value}}{\text{initial value}} \times 100[/tex]

From given,

Initial value = 376

Final value = 421

[tex]Percent\ increase = \frac{421-376}{376} \times 100\\\\Percent\ increase = \frac{45}{376} \times 100\\\\Percent\ increase = 11.968 \%[/tex]

Thus the equation is found and solved

What is the volume of the cone to the nearest whole number?
A) 31 m3
B) 94 m3
C) 188 m3
D) 283 m3

Answers

Answer:

It is 94

Step-by-step explanation:

The volume of a cone with a height of 10 meters and a radius of 3 meters is

94 m³.

What is a cone?

A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreasing to a certain point.

The volume of a cone is (1/3)πr²h.

The total surface area of a cone is πr(r + l).

The curved surface area is πrl.

Given, A cone has a radius of 3 meters and a height of 10 meters.

Therefore, The volume of this cone is,

= (1/3)π(3)²×10 m³.

= 30π m³.

= 30×3.14 m³.

= 94.2 m³ or 94 m³.

b) Cite evidence to support your claim.

c) Explain your thinking.

Answers

Answer:

a) I think Aaron is correct.

Step-by-step explanation:

Aaron and Blake are having a disagreement during math class. Aaron says 0.3838 is a terminating decimal while Blake says it's a repeating decimal.

a) I think Aaron is correct.

b) If we convert the decimal into fraction then this will give

[tex]0.3838 = \frac{3838}{10000} = \frac{1919}{5000}[/tex]

c) So the fraction [tex]\frac{1919}{5000}[/tex] has an exact value of 0.3838 and this does not repeat. Hence, this is a terminating decimal. (Answer)

Answers

Answer:

(2,8) and (8,32)

Step-by-step explanation:

ratios can be written as x:y or x/y

so look at what is given

(4,16)....4/16 reduces to 1/4

(6,24)...6/24 reduces to 1/4

so the pattern is  ur either dividing y by 4 and getting x....or ur multiplying x by 4 and getting y

and since ur other 2 points given dont have y, we will multiply x by 4 to get y.

(2,y).....lets multiply x, which is 2, by 4......2 * 4 = 8

so ur point is (2,8)

(8,y).....multiply x, which is 8, by 4.....8 * 4 = 32

so ur point is (8,32)

Determine whether each number could be the probability of an event. Explain your reasoning.

1.5

Answers

Answer:

1.5--> Not a probability

1---> Can be a probability

Step-by-step explanation:

The range of the probability of an event is given by 0≤P(E)≤1

The probability of an event E, P(E) cannot be greater than 1.

This means P(E)≠1.5

P(E)=1 could be a probability of an event because it falls within the range.

Probability of an event being 1, means the event is certain to happen.
