Three friends have a total of 6 identical pencils, and each one has at least one pencil. In how many ways can this happen?

Answer:

x=3y

Step-by-step explanation:

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer: 176

Step-by-step explanation:

To evaluate the equation we have to remove the parentheses and add 15 + 17...

1/2 (11)(15 + 17) =

= 11 * 32 * 1/2

Now, we have to turn it into a fraction and multiply it...

\(\frac{1*11*32 }{2}\)

= \(\frac{352}{2}\)

352 ÷ 2 = 176

I hope this helps!

Answer:

\(176\)

Step-by-step explanation:

\( \frac{1}{2} \times 11 \times (15 + 17) \\ \frac{1}{2} \times 11 \times 32 \\ \frac{352}{2} \\ = 176\)

Answer:

37.5%

Step-by-step explanation:

You need to convert this fraction into a decimal to start. After you do this you need to turn the decimal into its percentage form. Soo 0.375 = 3/8 = 37.5%

Answer:

shaded area = 3/8 of whole shape = 3/8 * 100 =37.5% to do this without a calculator =  To convert 3/8 so you can write it as a decimal, simply divide the numerator by the denominator, like this:

= 3/8

= 3 ÷ 8

= 0.375  or show long division  3/2  / 2 (/2 /2 ) = 1.5 / 2 (/ 2) = 0.75 /2 =  0.375

Answer:

IT IS  D

Step-by-step explanation:

Assign the numbers to the number line in the following order:

2.15=2.15

220%=2.2

9/4=2.25

*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:

2.15, 2.2, 2.25

Answer:

3x^2 +8x -10=-8

Step-by-step explanation:

A quadratic equation is

ax^2 + bx +c=0

has a formula

-b ± sqrt( b^2 -4ac)

--------------------------

  2a

We know a = 3   b = 8 and c = -2

3x^2 +8x -2=0

Subtract 8 from each side

3x^2 +8x -2 -8=0-8

3x^2 +8x -10=-8

That is choice C

Answer:

C.

Step-by-step explanation:

Consider equation C:

3x^2 + 8x - 10 = -8

3x^2 + 8x - 2 = 0

Here a = 3, b = 8 and c = -2

Applying the quadratic formula:

x  = [-b +/-  √(b^2 - 4ac)] / 2a

x = [-8 +/- √(4(3)(-2)] / 2(3)

- which is the one in the question.

So it is equation C.

Answer:

-4.416 repeating

Step-by-step explanation:

Answer:

-53/12 or 4 5/12 either works

Step-by-step explanation:

Let's turn the mixed fractions into improper fractions.

-7 2/3 = -23/3

-5 1/2 = -11/2

8 3/4 = 35/4

Now we need to find Least Common Denominator.

12 is the LCD because

3*4 = 12 is for -23/3

2*6 = 12 is for -11/2

4*3 = 12 is for 35/4

Now you will multiply the improper fractions by the 2nd number.

\(-\frac{23}{3}*(\frac{4}{4}) = -\frac{92}{12} \\\\-\frac{11}{2}*(\frac{6}{6}) = -\frac{66}{12} \\\\\frac{35}{4}*(\frac{3}{3}) = \frac{105}{12}\)

Now that they have the same denominators just put the numerators in the equation.

-92 + -66 + 105 = -53

-53/12 or -4 5/12

Hope this helps ya!

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

Simplifying:

V ≈ 1363.04 cubic inches

Answer:

Two expressions are equivalent if they can be simplified to the same third expression or if one of the expressions can be written like the other. In addition, you can also determine if two expressions are equivalent when values are substituted in for the variable and both arrive at the same answer.
