13/11,24/13,11/13,11/24
Answer:
65:55, 55:65, 55:120
Step-by-step explanation:
Fiberglass boats are = 65 because 120-55=65
Fiberglass to wood means that there is a 65:55 ratio because there are 65 fiberglass boats and 55 wood boats
wood to other, this is kind of a trick question, but its 55:65 because there are 65 other boats and 55 wooden boats
wood to total, this is 55:120 there are 55 wood boats and 120 total boats.
Use the expression 5a – 2b – 3 + 2b – 6a.
Part A
Simplify the expression.
–4
2a – 4b
–a – 3
a – 3
Part B
Which of the following is an equivalent expression?
–(3 + a)
–a + 3
–(a – 3)
–3 + a
Answer:
5a + (-6a) + (-2b) + 2b + (-3) = -a -3 or -(a + 3) so first answer is correct because -(a + 3) is the same as -(3 + a)

a reflection of the pink triangle is shown. which transformation makes this reflection
Answer:
A reflection is a transformation representing a flip of a figure. Figures may be reflected in a point, a line, or a plane. When reflecting a figure in a line or in a point, the image is congruent to the preimage. A reflection maps every point of a figure to an image across a fixed line.

Tell whether the ratios form a proportion. 30/75, 24/60
Given:
The ratios are [tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex].
To find:
Whether the ratios form a proportion or not.
Solution:
If two ratios represent the same relationship then they form a proportion.
We have,
[tex]\dfrac{30}{75}[/tex] and [tex]\dfrac{24}{60}[/tex]
Write the given ratios in the simplified forms.
[tex]\dfrac{30}{75}=\dfrac{15\times 2}{15\times 5}[/tex]
[tex]\dfrac{30}{75}=\dfrac{2}{5}[/tex]
And,
[tex]\dfrac{24}{60}=\dfrac{12\times 2}{12\times 5}[/tex]
[tex]\dfrac{24}{60}=\dfrac{2}{5}[/tex]
Since [tex]\dfrac{30}{75}=\dfrac{24}{60}=\dfrac{2}{5}[/tex], therefore the ratios form a proportion.
A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
Answer:
8 batches
Step-by-step explanation:
A recipe for cookies calls for 2/3 of a cup of sugar. Elena used 5 1/3 cups of sugar to make multiple batches of cookies. How many batches did she make?
From the above question, 1 recipe = 1 batch of cookies
Hence:
2/3 cup of sugar = 1 batch of cookies
5 1/3 cups of sugar = x batches of cookies
Cross Multiply
2/3 cup × x batches = 5 1/3 cup × 1 batch
x batches = 5 1/3 cup × 1 batch/2/3 cup
x batches = 16/3 ÷ 2/3
x batches = 16/3 × 3/2
= 8 batches
Therefore she made 8 batches

18 rice cakes weigh a total of 130 g. There are 329 calories in 100 g of rice cakes. How many calories are there in one rice cake?
Answer:
1 rice cake has 23.761 calories
Step-by-step explanation:
18 rice cakes weigh a total of 130 g.
There are 329 calories in 100 g of rice cakes.
Step 1
We calculate the number of calories is 18 rice cakes
18 rice cakes = 130g
Hence,
100g = 329 calories
130g = x
Cross Multiply
100g × x = 130g × 329 calories
x = 130g × 329 calories/100g
x = 427.7 calories
Therefore, 18 rice cakes had 427.7 calories
Step 2
How many calories are there in one rice cake?
18 rice cakes = 427.7 calories
1 rice cake = x
Cross Multiply
18 × x = 1 × 427.7
x = 427.7/18
x = 23.761111111 calories
Approximately = 23.761 calories
Therefore, 1 rice cake has 23.761 calories

Find the mean of 65, 67, 69, 67, 63, 60,60
Answer:
64.428
Step-by-step explanation:
well to find the mean we add all of the numbers up and then divide it by the amount of numbers in the sequence
so if we add all of the numbers up it will give us
451
then if we divide that by the number of numbers in the sequence which is 7 then that will leave us with
around 65 or exactly it would be
64.428
