Answer: 6 purple rectangles

Step-by-step explanation: We know that each scarf will have 5 rectangles and 2/5 of the rectangles will be purple: 2/5 * 5 = 2. It means that each scarf will have 2 purple rectangles. And for 3 scarves : 3 * 2 = 6. Answer: She needs 6 purple rectangles.

Answer:

Balin could bench press 256 pounds.

Step-by-step explanation:

Jasper was able to bench press 224 pounds, which is 7/8 of x, which is the weight that Balin was able to bench press. So, mathematically:

[tex]\frac{7}{8}x = 224[/tex]

[tex]7x = 224*8[/tex]

[tex]x = \frac{224*8}{7} = 256[/tex]

Balin could bench press 256 pounds.

Answer:

370 millimeters of compound B is needed for 666 millimeters of solution.

Step-by-step explanation:

Given that:

4 millimeters of compound A are used for every 5 millimeters of compound B.

The scientist wants to make 666 millimeters of solution.

Let,

x be the multiplier number of the compounds in the solution.

Then,

4x + 5x = 666

9x = 666

Dividing both sides by 9

[tex]\frac{9x}{9}=\frac{666}{9}\\x=74[/tex]

Millimeters of compound B = 5x = 5(74) = 370 millimeters

Hence,

370 millimeters of compound B is needed for 666 millimeters of solution.

Answer:

Positive

Step-by-step explanation:

There are a couple ways we can go about this.

First, we can see that as x increases, so does y, so that means its positive

For perspective, if x is the amount of time and y is the number of sales, we can see that the sales are going up and not going down or staying at the same place

If you wanna check your work on that, you can plot two points and find the slope using y1-y1/x1-x2 and the slope will be positive.

We can also use the process of elimination, we know it can't be zero because it's not a straight, horizontal line and we know its not undefined because it isn't a straight vertical line, so it's between negative and positive, and since the line is going up, that means that it's positive.

Answer:

2/23

Step-by-step explanation:

I think it's because there's 2 students out of 23 students who have a cat and a dog. So, I'm assuming the answer is 2/23

Answer:

2/12

Step-by-step explanation:

Step-by-step explanation:

The line is a vertical line of the form x = a, where a is a real constant.

Sincw the line passes through the point (-5, 0), the line equation is x = -5.

1. There are 26 letters in the alphabet. Only one of those letters is A. Thus, the probability of picking A is 1/26.

2. Out of the 26 letters, two are either A or B. Thus, the probability would be 2/26, or 1/13.

3. 1/26 letters in the alphabet are Z thus there is a 1/26 probability in picking this letter.

4. There are 5 vowels in the alphabet. Thus, the probability would be 5/26.

5. There are 21 consonants in the alphabet, thus the probability of selecting a consonant fron the alphabet would be 21/26.

6. 4/26, as there are 4 unique letters from the alphabet in the name Bryn.

7. 8/26, as there are 8 letters before I in the alphabet.

8. 5/26 because there are 5 letters in the alphabet following the letter U

9. 11/26 because there are 11 letters between I and U.

10. 0/26 because there are no numbers in the alphabet.

He sold cars from age 23 to 43, which is 20 years ( 43-23 = 20)

He started selling planes at age 43, so he sold cars for 20 years out of 43 years.

The fraction is number of years he sold cars / number of total years.

Fraction = 20/43

Answer:

77.6

Step-by-step explanation:

Given the data:

Weighting :

First exam = 20% ; second exam = 30% ; third exam = 50%

Scores :

First exam = 67 ; second exam = 84 ; third exam = 78

Weighted Average :

Σ(Weight * Score)

Σ[(0.2 * 67) + (0.3 * 84) + (0.5 * 78)]

13.4 + 25.2 + 39

= 77.6

Based on the weights assigned to these grades, Emily's weighted average in the class would be 77.6 marks.

= ∑ (Percentage of grade x Score in exam)

Solving gives:

= (20% x 67) + ( 30 % x 84) + (50% x 78)

= 13.4 + 25.2 + 39

= 77.6

Emily's weighted average is 77.6 marks.

Answer:

4.5m

Step-by-step explanation:

The set up is a right angles triangle

Height of the shed = opposite side = 6cm

Distance of the ladder from the shed = adjacent = 4.5m

Lenght of the ladder = Hypotenuse = x

Using pythegoras theorem to find the length of the ladder

hyp² = opp²+adj²

hyp² = 0.06² + 4.5²

hyp²= 0.0036+20.25

hyp² = 20.2536

hyp = √20.2536

hyp = 4.50m

Hence the length of the ladder is 4.5m

Answer:

$97 = (Original Price) - (35% of Original Price)

$97 = (Original Price) - (0.35 of Original Price)

$97 = (1 - 0.35) of (Original Price)

$97 = (0.65) of (Original Price)

$97 = 0.65 · (Original Price)

Divide each side by 0.65 .

$97/0.65 = Original Price

$149.23 = Original Price

Answer:

[tex](x,y) = (0,1)[/tex]

Step-by-step explanation:

Given

The above table

Required

Determine the coordinates of the y intercept

Represent points on the table as:

[tex](x_1,y_1) = (4,2)[/tex]

[tex](x_2,y_2) = (8,3)[/tex]

First, calculate slope (m):

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{3-2}{8 - 4}[/tex]

[tex]m = \frac{1}{4}[/tex]

For y intercept, the following coordinate point exist:

[tex](x_3,y_3) = (0,y)[/tex]

Because x = 0 at y intercept

Calculate the slope as:

[tex]m = \frac{y_3 - y_1}{x_3 - x_1}[/tex]

The equation becomes

[tex]\frac{1}{4} = \frac{y - 2}{0 - 4}[/tex]

[tex]\frac{1}{4} = \frac{y - 2}{- 4}[/tex]

Cross Multiply:

[tex]4(y-2) = -4 * 1[/tex]

Divide through by 4

[tex]y - 2 = -1 * 1[/tex]

[tex]y - 2 = -1[/tex]

Make y the subject:

[tex]y = 2-1[/tex]

[tex]y = 1[/tex]

Hence, the coordinates of the y intercept is:

[tex](x,y) = (0,1)[/tex]

Answer:m<k+m<k=180+167-133=100

Step-by-step explanation:

Answer:

The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. Genes provide rules for making particular energy, so mosquitos with different mixtures of genes will have different proteins in their cells that end up in different body sizes. Each parent randomly gives on one out of two of a gene for a characteristic, which is why each mosquito babies can have different mixtures of genes, even though they have the same parents.
