Answer:

20.5714285714

Step-by-step explanation:

multiply 48×3÷7=144÷7=20.5714285714

Answer:

If $1: 1500 items

If $20: 75 items

If those answers are not applicable, divide 1500 by whatever the cost of the shoes he is selling — that will be how many he will need to sell.

Step-by-step explanation:

So first lets set up an equation to figure this out.

So we know that he makes 20% based off of sales, so we’ll convert this to a decimal:

20% -> .20

Next we’ll make an equation to see what is needed to get at least $500.

0.20x + 200 = 500

Next we’ll have to get x by itself.

[tex]0.20x + 200 = 5000.20x = 300[/tex]

Next divide both sides:

[tex]X = 1500[/tex]

So if he is making sales of $1 he will need to sell 1500 items.

If he is selling them at $20, he will need to sell 75 items.

What ever the price value is for the items, divide that from 1500.

Answer:

The value of x=34 will make parallelogram ABCD a rhombus.

Answer: x is 13

Step-by-step explanation:

90 - 67 is 23. Then you figure out what times 2 minus 3 is 23. Which would be 13. 13 times 2 is 26 minus 3 is 23. 67 + 23 is 90 ( right triangle)

Answer:

x=13

Step-by-step explanation:

The two angles are complementary, meaning that they both add up to 90°.

So, since we know that one of the angles is 67°, we can find the other one by subtracting 67 from 90.

90-67=23

So the equation is equal to 23.

2x-3=23

Add 3 to both sides.

2x=26

Divide both sides by 2.

x = 13

Answer:

Step-by-step explanation:

[tex]9x + 1 + 5x + 12 + 10x - 37 = 360[/tex]

[tex]24x - 24 = 360[/tex]

Add 24 to both sides

24x/24=384/24

[tex]answer = 16[/tex]

Answer:

8km/h

Step-by-step explanation:

The computation of the average speed is shown below:

In the case of upstream, the speed is

= 9 - 3

= 6km/h

And, the time would be

= 1.5km ÷ 6

= 0.25h

In the case of downstream, the speed is

= 9 + 3

= 12

The time would be

= 1.5km ÷ 12

= 0.125h

Now the average speed is

= 3 ÷ (0.25 + 0.125)

= 8km/h

Answer:

24 in long by 12 in wide.

Step-by-step explanation:

l=2w

288=(2w)×w

288=2w^2

144=w^2

12=w

use w=12 to solve for l

l=2(12)

l=24

Eli will bike 20.5 miles in 2 hours

Firstly ,

We know 1 minute = 60 seconds

Then 15 feet / seconds = 15*60 = 900 feet

Eli bikes 900 feet in one minute

Now, We know

1 hour = 60 minutes

900*60=54000 feet

In 1 hour Eli bikes 54000 feet

In 2 hours Eli bikes 54000*2 = 1,08,000 feet

Now for converting feet into miles

1 mile = 5.280 feet

For 1,08,000 feet

1,08,000 / 5.280

= 20.4545 ≈ 20.5

Hence In 2 hours Eli bikes 20.5 miles

C) 50

Step-by-step explanation:

50

Answer:

C: 50

Step-by-step explanation:

The inner diamond has congruent sides

Half of the line segment on the left is 25.

The other half of the left line segment is also 25

Together, the left line segment is 50 units

The inner diamond has both 90 degree angles and 18 unit long sides

Thus, we know that both sides are congruent

Finally, the right side is the same length as the left side

The right side is 50 units long

Step-by-step explanation:

We will have the following

*First: We have that the area of a sector of a circle is given by the expression:

A = r²a/2

Here r is the radius and alpha is the central angle.

*Second: We determine the central angle as follows:

[tex]36\pi =[/tex]

(12)²a/2 ➡️ a = 36í•2/(12) ²➡️

[tex]a = \frac{1}{2} \pi[/tex]

So, the central angle has a measurement of 1/2 pi.

Third: We determine the perimeter of the sector as follows:

First: we determine the arc length with two times the radius, that is:

p = 2(12) +

[tex]6\pi[/tex]

➡️ p = 24 +

[tex]6\pi[/tex]

So, the perimeter of the sector is 24+ 6pi meters [ Approximately 43 meters].

Answer:

0.83

Step-by-step explanation:

(a) z = (x - mean) / sd = (4000 - 3750) / 300 = 0.83

This corresponds to 0.7967 from the z-table, which represents how many last less than 4000 hours, so the answer is 1 - 0.7967 = 0.2033

(b) It will be P(x<4000) - P(x>3600) = 0.7967 - whatever the corresponding value is.

(c) same procedure as (b).

(d) 2% above corresponds to 0.02 which is a z-score of -2.05

-2.05 = (x - 3750) / 300

x = 3135

Answer:

67

Step-by-step explanation:

(90÷18)-(18÷6)-(6÷3)= 72-3-2= 67

Answer:

∠3 = 18°

∠4 = 144°

∠2 = 36°

∠1 = 72°

Step-by-step explanation:

From the concept of alternate interior angles,

∠3 = 18°

Since the diagonal divides the rectangle into 4 parts with 2 of the rectangles being similar.

Then, the triangle with ∠3 & ∠4 is an Isosceles triangle and as such;

∠4 = 180 - 2(∠3)

∠4 = 180 - 2(18)

∠4 = 180 - 36

∠4 = 144°

∠2 = 180 - ∠4 (because sum of angles on a straight line is 180°)

∠2 = 180 - 144

∠2 = 36°

Like it was done for angle ∠4 above;

∠1 = (180 - 36)/2

∠1 = 144/2

∠1 = 72°
