Emy paid 24.50 for 4 baskets of apples. How much did she pay for each basket?

Bonus: How much will it be for 10 baskets.

Please help me it will be very much appreciated!
Due in one hour.

Answers

Answer:

6.125

Step-by-step explanation:

Divide 24.50 by 4!

Answer:

$6.13 for each basket.

Bonus: $61.30 for ten baskets.

Step-by-step explanation:

To solve this, we would divide the $24.50 by four, because there are four baskets. We now know that she paid $6.13 (rounded from $6.125) for each basket. To solve for 10 baskets, you would take the price per basket of $6.13 and multiply it by ten, resulting in $61.30 for all ten baskets.

Point F is on line segment EG. Given FG = 3x – 5, EF = x
, and
EG = 5x – 8, determine the numerical length of FG.

Answers

Answer:

3

Step-by-step explanation:

the whole line equals

5x-8 as well as x+3x-5

since it equals both we know the equation is

5x-8=x+3x-5 simplify to 4x-5

5x-8=4x-5

-5x.    -5x

-8=-1x-5

+5.     +5

-3= -1x

-/.     -/

3=x

we now can double check our work by putting 3 everywhere the x is

EG =7

FG= 4

making EF 3

Answer:

2/5

Step-by-step explanation:

Use the distance formula to determine the distance between two points.

Answer:

The distance is

3√10  or about 9.49 (rounded to nearest hundredth's place).

Step-by-step explanation:

The distance is

or about

9.49

(rounded to nearest hundredth's place).

Explanation:

The formula for the distance for 3-dimensional coordinates is similar or 2-dimensional; it is:

(

We have the two coordinates, so we can plug in the values for

(I wasn't sure if the

Now we simplify:

d

d=√90

d=3√10

If you want to leave it in exact form, you can leave the distance as

3√10

. However, if you want the decimal answer, here it is rounded to the nearest hundredth's place:

d≈9.49

5. Two blueberry farms are similar in shape. The ratio of the side lengths of
the farms is 5:6, and the smaller farm has a perimeter of 360 yards. The
cost to dig a trench is $0.75 per yard. What is the cost to dig a trench
around the larger blueberry farm?

Answers

Answer:It would cost $270 to dig

Step-by-step explanation:<!>Brainliest Apprecatied<!> :D

Answer: $324

Step-by-step explanation:

For this question, many people think the answer is 270, but that's wrong.

Since the ratio is 5:6 and the smaller farm perimeter we can put that into an ratio equation.

x will be the perimeter of the bigger farm

5/6=360/x

5x=2160

5x/5=2160/5

x=432 yards

That's the perimeter, now to find the cost it would be 432*0.75 which is $324.

The results of a recent survey indicate that the average new car costs $23,000 with a standard deviation on $3,500. The prices of the car are normally distributed. a. If someone buys a car for $32,000, what proportion of cars cost an equal amount or more than this? b. If someone buys a car for $16,000, what proportion of cars cost an equal amount or more than this?

Answers

Answer:

(a) 0.0051

(b) 0.9773

Step-by-step explanation:

Let X = prices of the car.

It is provided that [tex]X\sim N(23,000, 3,500^{2})[/tex].

(a)

Compute the value of P (X ≥ 32000) as follows:

[tex]P(X\geq 32000)=P(\frac{X-\mu}{\sigma}>\frac{32000-23000}{3500})[/tex]

                       [tex]=P(Z>2.57)\\=1-P(Z<2.57)\\=1-0.99492\\=0.00508\\\approx 0.0051[/tex]

Thus, the proportion of cars cost an equal amount or more than $32,000 is 0.0051.

(b)

Compute the value of P (X ≥ 16000) as follows:

[tex]P(X\geq 16000)=P(\frac{X-\mu}{\sigma}>\frac{16000-23000}{3500})[/tex]

                       [tex]=P(Z>-2)\\=P(Z<2)\\=0.97725\\\approx 0.9773[/tex]

Thus, the proportion of cars cost an equal amount or more than $16,000 is 0.9773.

The painting and frame together form a larger rectangle with length 25 \text{ cm}25 cm 25, start text, space, c, m, end text and width 20 \text{ cm}20 cm 20, start text, space, c, m, end text. Find the area of the frame.

Answers

Answer:

180cm²

Step-by-step explanation:

Area of the frame = area of the frame+ painting - area of painting.

Area of a rectangle = Length × Width

Area of the painting = 20cm×16cm

Area of the painting = 320cm²

Area of the paint+ frame = 25cm×20cm

Area of the paint+ frame = 500cm²

Area of the frame = 500cm²-320cm²

Area of the frame = 180cm²

Hence the area of the frame is 180cm²

Considering this in the equation 2:

s + 2*300 = 1400s = 1400 - 600s = 800

Substituting s in the equation 1:

A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3 4 pounds the first month and 11 5 8 pounds the second month. How much weight must be lost the third month for the goal to be achieved?

Answers

Given :

A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3/4 pounds the first month and 11 5/8 pounds the second month.

To Find :

How much weight must be lost the third month for the goal to be achieved.

Solution :

Let, weight lose in third month is x.

So, 8 3/4 + 11 5/8 + x = 26

[tex]\dfrac{32+3}{4}+\dfrac{88+5}{8}+x=26\\\\x = 26 - ( \dfrac{35}{4}+\dfrac{93}{8})\\\\x=5.625\ pounds[/tex]

Therefore, weight lose in third month is 5.625 pounds.

Hence, this is the required solution.

Answers

Answer:

x = -3

Step-by-step explanation:

Answer:

-3

Step-by-step explanation:

To find the value of x, you need to get rid of parentheses! So, 4*x=4x. 6*4=24. Now we have, -2x+6=4x+24. Then we want to get all the x on one side, and the other numbers on the other side. We can add -2x to make it 0, but to make it equal, you need to add it to the other side. So, 4x+2x=6x. You can subtract 24 too! After we do all that, we get: -18=6x. To get x, we need to divide by 6. 6x/6=x. -18/6=-3.
