Answer: 1/3 and t/9

there are 3 trombones in the orchestra

Step-by-step explanation: it says the ratio of trombones to violas is 1/3 so that’s ur first one and it says there’s 9 violas so there’s ur 2nd one. 9 divided by 3 is 3 so you would multiply 1 by 3 and the answer is 3, making it 3 trombones in the orchestra

The correct answer is 3/9 and t/9

Mr. Townsend needs to make 13 pairs of butterfly wings for costumes for a pay. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.

You'll apply properties of multiplication in the following questions to find the total cost of the fabric.

2. Multiply the amount of fabric by the price per yard to find an expression for the total cost. Show your work.

Answers

1 pair of wings = 3/4 yd. To find the price of one pair of wings, you get 3/4 of $8 which is $6. Mr. Townsend needs 13 wings.
$6/pair x 13 pairs =
$78 for 13 pairs of wings.

13 wings is $78

If each wing is 3/4 a yard and a yard is $8 you do .75x8=$6 so it costs $6 per wing

Then to find how much for 13 wings do 13x6=78

An architect plans a courtyard with a length of 16.4 yards, then learns its width must change by −2.3 yards. What is its new width?

Answers

Answer:

The answer is 14.1

Step-by-step explanation:

16.4+-2.3=14.1

-2.3 isnt large enough to make 16.4 a negative.

The new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

What is a rectangle?

It is defined as two-dimensional geometry in which the angle between the adjacent sides is 90 degrees. It is a type of quadrilateral.

It is defined as the area occupied by the rectangle in two-dimensional planner geometry.

The area of a rectangle can be calculated using the following formula:

Rectangle area = length x width

It is given that:

An architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards.

Let new width be x:

x = old width + (change in width)

Change in width = -2.3

x = 16.4 + (-2.3) = 14.1 yards

Thus, the new width is 14.1 yards if the architect plans a courtyard with a width of 16.4 yards, then learns its length must change by -2.3 yards option (B) 16.4 + (-2.3) is correct.

Hey there!

Let's write this as a ratio/proportion.

The sum of this basic ratio is 4.25.

To figure out how much of each we have for 34, we divide this 34 by 4.25, our sum of the two ingredients. This will give us a factor we can multiply our two ingredient measurements by.

34/4.25=8

Now, we multiply our two ingredients by eight.

2.75(8)=22

1.5(8)=12

Note that these two add up to make 34 tablespoons.

Therefore, we have...

22 tablespoons of olive oil and 12 tablespoons of balsamic vinegar were used in the 34 tablespoons of bread dip.
