Answer:

610 feet

Step-by-step explanation:

From the question :

1 scarf = 2.5 yards of yarn

84 scarves = x yards

Cross Multiply

1 scarf × x yards = 84 × 2.5 yards

x yards = 210 yards

Hence, 84 scarves require 210 yards

Converting yards to feet

1 yard = 3 feet

210 yards = x feet

x feet × 1 yard = 210 yards × 3 feet

x feet = 210 yards × 3 feet/1 yards

x feet = 610 feet

Hence, if Janet wants to make 84 scarves, she need to buy 610 feet of yarn

Step-by-step explanation:

so to figure out how much more you grab 20 and multiply by .15 as percent and you will get 3 dollars more so 23

Step-by-step explanation and answer:

The 6 sides of the die are numbered 1,2,3,4,5,6

There are 3 odd and 3 even numbers

probability of an odd number on 1st roll is:

3/6=1/2

When you want A AND B probabilities, you multiply

the events A and B

The number less than 3 are 1,2, so the probability is:

2/6=1/3

so the probability of both events are going to be:

(1/2) *(1/3)=1/6

Answer: D.Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles.

Step-by-step explanation: 24 times 20 is 480. That is how many she made all together.

Lindsay makes 480 candles. She divides 480 by 15 to get 32. She does not make enough candles and this can be determined by using the arithmetic operations.

Given :

The following steps can be used in order to determine whether Lindsey makes enough candles to reach her goal:

Step 1 - The arithmetic operations can be used in order to determine whether Lindsey makes enough candles to reach her goal.

Step 2 - According to the given data, Lindsey makes 24 candles each day for 20 days. So, the total number of candles she makes at the end of 20 days is:

[tex]=24\times 20[/tex]

= 480 candles

Step 3 - Also it is given that Lindsey’s goal is to sell at least 35 candles at each of 15 craft fairs. So, the total candles required is:

[tex]=35\times 15[/tex]

= 525 candles

Therefore, the correct option is D).

Answer:

The new temperature is 13 degrees Fahrenheit

Step-by-step explanation:

Answer:

Let's define:

A = # of students in group A

B = # of students in group B

C = # of students in group C.

"The total number of students who could attend a field trip is represented by the variable t."

This can be written as:

A + B + C = t.

"The number of students in Group A is less than the number in Group B."

Here we have a strictly "less than", then this is written as:

A < B.

"Group A has 6 students more than 1/4 the total number of students"

A = t/4 + 6

"Group B has 3 less than the total number of students"

B = t - 3.

Then we have the equations:

A + B + C = t.

A = t/4 + 6

B = t - 3.

A < B.

We could replace the second and third equatio in the fourth one, to get:

t/4 + 6 < t - 3.

t/4 + 9 < t

9 < t - t/4

9 < t*(4/4 - 1/4)

9 < t*(3/4)

(4/3)*9 < t

12 < t.

Then we found an inequality that defines the minimum possible value of t,

Answer: 11718.75 I think.

Answer:

$11,718.75

Step-by-step explanation:

If $1,875,000 is the median salary, it means that was the top salary for all the 160 games

So, the answer is simply given by:

sry if im wrong :)

The amount after 4 years will be equal to $9,724.05

The interest earned on savings that are computed using both the original principal and the interest accrued over time is known as compound interest.

Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-

Given that Mr.Turner invested $8,000 in an account for his daughter’s college education. The account pays 5% interest, compounded yearly.

The amount after 4 years will be calculated as:-

[tex]A = P ( 1 + \dfrac{r}{100})^{nt}[/tex]

[tex]A = 8000 ( 1 + \dfrac{5}{100})^{4}[/tex]

A =  9724.05

Therefore, the amount after 4 years will be equal to $9,724.05.

Answer:

y = 1/2 x + 3

Step-by-step explanation:

mid point of line BC = (2, 4)

slope of the line containing median (m) = 1/2

y intercept (b)= 3

since y = mx + b

y = 1/2x + 3

The median of a triangle is the line segment joining the any of the vertex to the mid-point of the opposite side of that vertex. The equation of the median through point A is given by y = 1/2x + 3.

A median of a triangle is a line segment joining one of the vertex of the triangle to the mid-point of the opposite side.

The median of an equilateral triangle also an angular bisector.

Given that,

The coordinates of A = (-2, 2)

The coordinates of B = (4, 10)

The coordinates of C = (0,-2)

Thus the coordinate mid-point of BC is given by (4+0)/2,(10-2)/2 = (2,4).

Now, to find the equation of median through A there are two points (-2,2) and (2,4).

Thus the equation of median an be written as,

(y-2)/(x+2) = (4-2)/(2-(-2))

=> y - 2 = 1/2(x+2)

=> y = 1/2(x+2) + 2

=> y = 1/2 x + 3

Hence, the equation of the line is y = 1/2 x + 3.

Answer:

Bruno = 15 years

Mother = 8 + 2(15) = 38 years

Father = 38 + 3 = 41 years

Step-by-step explanation:

Given that :

Let

Bruno's age = x

Mothers age = 8 + 2x

Father's age = 8 + 2x + 3 = 2x + 11

x + 8 + 2x + 2x + 11 = 94

5x + 19 = 94

5x = 75

x = 75 /5

x = 15

Bruno = 15 years

Mother = 8 + 2(15) = 38 years

Father = 38 + 3 = 41 years
