An Orchestra has twice as many woodwind instruments as brass instruments. There are a total of 150 brass and wood instruments.
How would I write and two different addition equations to describe this situation? Please help!

Answer:

There are 8 and 12 balloons for groups A and B, respectively.

Step-by-step explanation:

The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:

Group A

[tex]n_{A} = \frac{2}{2+3}\cdot (20)[/tex]

[tex]n_{A} = 8[/tex]

Group B

[tex]n_{B} = \frac{3}{2+3}\cdot (20)[/tex]

[tex]n_{B} = 12[/tex]

There are 8 and 12 balloons for groups A and B, respectively.

Given:

Elise is making punch for the party that requires 2 parts of fruit juice for every 5 parts of ginger ale.

To make the punch, she uses 18 ounces of fruit juice and 3 containers of ginger ale.

To find:

The number of ounces in each container of ginger ale.

Solution:

Let n be the number of ounces in each container of ginger ale.

According to the question, the ratio of fruit juice and ginger ale is 2:5. it means,

[tex]\dfrac{\text{Fruit juice}}{\text{Ginger}}=\dfrac{2}{5}[/tex]

[tex]\dfrac{18}{\text{Ginger}}=\dfrac{2}{5}[/tex]

[tex]5\times 18=2\times \text{Ginger}[/tex]

[tex]90=2\times \text{Ginger}[/tex]

Divide both sides by 2.

[tex]45=\text{Ginger}[/tex]

So, ginger required for punch is 45 ounces.

Number of containers = 3

Number of ounces in each container of ginger ale = n

Number of ounces in 3 containers of ginger ale = 3n

Now,

[tex]3n=45[/tex]

Divide both sides by 3.

[tex]n=15[/tex]

Therefore, 15 ounces are in each container of ginger ale.

Answer:

  x = 3

Step-by-step explanation:

Each line shows you the output value for a given input value. If you want a particular input value to give the same output for both functions, then you need to find the point where the lines cross. This question asks for the input value at that point, the x-coordinate.

The lines cross at (x, y) = (3, -1), so x = 3 produces the same output from both functions.

Answer:

Step-by-step explanation:

A + B + C = 180

x + x - 24 + 68 = 180

2x - 24 + 68 = 180

2x + 44 = 180

2x = 180 - 44

2x = 136

x = 68

A = 68

B = 44

C = 68

Answer:

solution given:

A=l w

now

dividing both side by w ,we get

[tex] \frac{A}{w} [/tex]=[tex] \frac{lw}{w} [/tex]

l =[tex] \frac{A}{w} [/tex]

Answer:

The answer should be about $81.20

Step-by-step explanation:

$14.50 x 5weeks = $72.50

A school week is usually 5 days.

The middle of the week is Wednesday, so that's 3 whole days.

$14.50 / 5days = $2.90 per day

$2.90 x 3days = $8.70

$72.50 + $8.70 = $81.20

Answer:

−30a−6

Step-by-step explanation:

Let's simplify step-by-step.

−9a−10−6a+7−9a−10−6a+7

=−9a+−10+−6a+7+−9a+−10+−6a+7

Combine Like Terms:

=−9a+−10+−6a+7+−9a+−10+−6a+7

=(−9a+−6a+−9a+−6a)+(−10+7+−10+7)

=−30a+−6

Answer:

(-6, 6)

Step-by-step explanation:

The coordinates of B to start with is

(-2, 2)

To dilate this by a factor of 3....

-2 * 3 = -6

2 * 3 = 6

The new coordinates of B' would be

(-6, 6)

A few things to know:

- The number 3 is called a "scale factor"

- Dilation means we are multiplying all the (X, Y)'s by the scale factor

- If the scale factor is greater than 1, the size of the shape overall increases

- If the scale factor is less than 1, the size of the shape overall decreases

- If the scale factor is negative, the shape size stays the same. The shape just rotates 180 degrees and moves to the opposite quadrant.

Answer:

She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.

Step-by-step explanation:

She switched the divisor and the dividend when creating an equation to model the problem in step 1.

She replaced both the divisor and the dividend with their reciprocals when changing division to multiplication in step 2.

She multiplied the two numerators and the two denominators to generate her product in step 3.

She reduced the improper fraction incorrectly when getting her final answer.

5/16 = 1/3h

Correct steps

Step 1:

h = 5/16 ÷ 1/3

Step 2:

h = 5/16 × 3/1

Step 3:

h = (5*3) / (16*1)

= 15/16

h = 15/16

Incorrect steps:

Step 1: StartFraction 5 Over 16 EndFraction divided by one-third = h

5/16 ÷ 1/3 = h

Step 2: StartFraction 16 Over 5 EndFraction times StartFraction 3 Over 1 EndFraction = h

16/5 × 3/1 = h

Step 3: StartFraction 48 Over 5 EndFraction = h Answer: 9 and three-fifths = h

48/5 = h

9 3/5 = h

Answer:

part.a  11.75

part.b 1.50

part.c 10.25

Step-by-step explanation

first you do is add your original prices first

then you go back to your percentages and sense the ground beef doesn't have a coupon off its the original price for that

and your coupons added up deduct from the price and 10.25 is your new answer

c is your answer

Answer:

B

Step-by-step explanation:

Expanding the products using FOIL , noting that i² = - 1

A

(2x - 4i)(x - 2i)

= 2x² - 4ix - 4ix + 8i²

= 2x² - 8ix - 8 ≠ 2x² + 8

B

(2x - 4i)(x + 2i)

= 2x² + 4ix - 4ix - 8i²

= 2x² + 8 ← True

C

(2x - 2i)(x + 6i)

= 2x² + 12ix - 2ix - 12i²

= 2x² + 10ix + 12 ≠ 2x² + 8

D

(2x + 4i)(x + 2i)

= 2x² + 4ix + 4ix + 8i²

= 2x² + 8ix - 8 ≠ 2x² + 8

Thus

(2x - 4i)(x + 2i) = 2x² + 8 → B

Answer:

In word form, 5.004 is five and four thousandths.

Step-by-step explanation:

The part to the left of the decimal is simple - it's just five.

The part to the right of the decimal is a bit more complicated. The digit one place to the right of the decimal is the tenths place. The digit to the right of the tenths place is the hundredths place. The digit to the right of the hundredths place is the thousandths.

With that in mind, you should find that the number 4 is in the thousandths place. So, your answer is five and four thousandths.

Hope this helped!

Answer:

£3591

Step-by-step explanation:

Brian buys a computer for £3600. It depreciates at a rate of 5% per year. How much will it be worth in 2 years? Give your answer to the nearest penny where appropriate.

The formula for Depreciation rate =

P = Po × e^-rt

P = Amount after depreciation

Po = Initial amount = £ 3600

r = depreciation rate = 5% = 0.05

t = time in years = 2

Hence:

P = £3600 × e ^ -0.05 × 2

P =£ 3600 × e-0.0025

P = £ 3591.0112406

Approximately = £3591

Answer:

x = 12

Step-by-step explanation:

Let the number be x.

9 added to twice a number is the same as 27 reduced by 4 times the number

If we add 9 to the number = (9+x)

If 27 reduced by 4 times the number = (4x-27)

ATQ,

(9+x) = (4x-27)

Taking like terms together,

x-4x = -27-9

-3x = -36

x = 12

Hence, the number be 12.

Answer:

  linear

Step-by-step explanation:

The slope of the line between the first pair of points is ...

  m = (y2 -y1)/(x2 -x1)

  m = (3 -2)/(1 -0) = 1/1 = 1

The slope of the line between the second pair of points is ...

  m = (4 -3)/(2 -1) = 1/1 = 1

The slopes are the same, so the points are on the same line. The graph is that of a linear function.
