Step-by-step explanation:

I believe it is 6

The fraction of total interest owed after the fifth month of a 12-month loan is 64.1%

From the question, we have the following parameters

After the fifth month, the equation of the numerator is:

Numerator = (1+11)+(1+10)+(1+9)+(1+8)+(1+7)

Numerator = 50

The equation of the denominator is:

Denominator = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12

Denominator = 78

The fraction of total interest is then calculated using:

Fraction = Numerator/Denominator

This gives

Fraction = 50/78

Express as percentage

Fraction = 64.1%

Hence, the fraction of total interest owed after the fifth month of a 12-month loan is 64.1%

Answer:

No

Step-by-step explanation:

So, you can use the distributive property.

1/2(6x)=3x

1/2(-2)=-1

It is 3x-1, not 3-x

Answer:4/9 We know, Probability = Favorable Outcome / Total Outcome

Here, Favorable Outcome (Number of Green Marbles) = 8

Total Outcome = 6 + 4 + 8 = 18

P = 8 /18 = 4/9

In short, Your Answer would be 4/9 or 0.44

Hope this helps!

Answer:

13 / 8 in

Step-by-step explanation:

Longest ( 1 7/8)  - shortest ( 2/8) = 13/8 in

a) Substitute t = 2 into the formula

= 600e^0.1(2)

= 600e^0.2

= 732.84 million

Therefore, 732.84 million bacteria are present after 2 days

b) Substituting t = 4 days we get

= 600e^0.1(4)

= 600e0.4

= 895.09 million

Hence, 895.09 million bacteria are present after 4 days

c) 2 weeks = 14 days

Substituting t = 14 days we get

= 600e^0.1(14)

= 600e^0.4

= 2433.12 million

Thus, 2433.12 million bacteria are present after 2 weeks

Answer: 2/5

1/5 you will keep

you will CHANGE the division sign to multiplication, never change when it is multiplication.

1/5 X 1/2

You will FLIP  2/1 into 1/2. Now multiply numerator x numerator, denominator x denominator.

1/5 X 1/2= 2/5

Now you have gotten your answer but for the future, the numerator should never be greater than the denominator, if it is, divide.

Answer:

○ [tex]\displaystyle (x - 4)^2 + (y + 2)^2 = 25[/tex]

Explanation:

Accourding to one of the circle equations, [tex]\displaystyle (x - h)^2 + (y - k)^2 = r^2,[/tex]the centre of the circle is represented by [tex]\displaystyle (h, k).[/tex]Moreover, all negative symbols give you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must pay cloce attention to which term gets which symbol. Another thing you need to know is that the radius will ALWAYS be squared, so no matter how your equation comes about, make sure that the radius is squared. Now, in case you did not know how to define the radius, you can choose between either method:

Pythagorean Theorem

[tex]\displaystyle a^2 + b^2 = c^2 \\ \\ 4^2 + 3^2 = r^2 \hookrightarrow 16 + 9 = r^2 \hookrightarrow \sqrt{25} = \sqrt{r^2} \\ \\ \boxed{5 = r}[/tex]

Sinse we are dealing with length, we only desire the NON-NEGATIVE root.

Distanse Equation

[tex] \displaystyle \sqrt{[-x_1 + x_2]^2 + [-y_1 + y_2]^2} = d \\ \\ \sqrt{[-7 + 4]^2 + [-2 - 2]^2} = r \hookrightarrow \sqrt{[-3]^2 + [-4]^2} = r \hookrightarrow \sqrt{9 + 16} = r; \sqrt{25} = r \\ \\ \boxed{5 = r}[/tex]

Sinse we are dealing with distanse, we only desire the NON-NEGATIVE root.

Answer:

18.17 × pi in²

Step-by-step explanation:

there are many seemingly different formulas out there for this, but they are actually all the same and differ only by what values of the cone we know at the beginning (and the custodian values are converted into the values we need for the calculation).

do we know the base area and the height of the cone, or the radius and the height, or the base area and the slant height (the length of the "mantle" straight from the bottom to the top), ... ?

well, here we know the diameter (this means it is 2 times the radius) and the slant height.

this is one of the easiest exercises.

the formula for this case is

LA = pi × radius × slant height = pi × (4.6 / 2) × 7.9 =

= pi × 2.3 × 7.9 = 18.17 × pi in²

The measure of AB and EF for the similar triangle ABC and DEF are 4 and 12 respectively.

Similar triangles are triangles that have the same shape, but their sizes may vary.

In similar triangles, corresponding sides are always in the same ratio. The angles are congruent.

ΔABC is similar to ΔDEF. Therefore, the sides will form a ratio.

AC / DF = BC / EF = AB/DE

AC = 10

DF = 20

DE = 8

BC = 6

Hence,

10 / 20 = AB / 8

cross multiply

20AB = 80

AB = 80 / 20

AB = 4

Hence,

10 / 20 = 6 / EF

10EF = 120

EF = 120 / 10

EF = 12

Answer:

Area of rectangle = 65/8 yd²

Step-by-step explanation:

The area of the rectangle is the length multiplied by the width. In this case, we are given the length 3 1/4 yd and the width 2 1/2 yd wide. Therefore,

        ⇒ Area of rectangle = (L × B) = (3 1/4 × 2 1/2) yd²

It is suggested to convert the terms in the expression (3 1/4 × 2 1/2) to improper fraction. Therefore,

        ⇒ Area of rectangle = [(3 × 4) + 1]/4 × [(2 × 2) + 1]/2 yd²

        ⇒ Area of rectangle = [(12) + 1]/4 × [(4) + 1]/2 yd²

        ⇒ Area of rectangle = [13]/4 × [5]/2 yd²

        ⇒ Area of rectangle = 13/4 × 5/2 yd²

Simplify the expression on the right hand side to determine the area.

        ⇒ Area of rectangle = 65/8 yd²

Thus, the area of the rectangle is 65/8 yd².

Answer:

  $18.06

Step-by-step explanation:

The price the pawn shop charged for the DVD player was 40% more than what it paid, so was ...

  $12.00 + $12.00 × 0.40 = $12.00×(1 +0.40) = $16.80

__

The tax on the purchase is this price multiplied by the tax rate:

  tax = 0.075×$16.80 = $1.26

__

Then the total including tax is ...
