For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 390 miles in 6 hours, how many
miles does it travel in 5 hours?

Answer:3:1

Step-by-step explanation:

Given

There are 27 solid spheres of  radius x cm

The volume of a sphere is [tex]\frac{4}{3}\pi r^3[/tex]

The volume of 27 old spheres is the same as the volume of a new sphere

The volume of the old spheres is

[tex]V_o=\dfrac{4}{3}\pi x^3[/tex]

The volume of a new sphere is

[tex]V_n=\dfrac{4}{3}\pi y^3[/tex]

Now,[tex]V_o=V_n[/tex]

[tex]\Rightarrow 27\times \dfrac{4}{3}\pi x^3=\dfrac{4}{3}\pi y^3\\\\\Rightarrow (\dfrac{x}{y})^3=27\\\\\Rightarrow \dfrac{x}{y}=3[/tex]

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°

Answer:

450

Step-by-step explanation:

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

The value of set of models is equivalent to the expression 2 x 4/6 is,

⇒ 4 / 3

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

⇒ 2 × 4/6

Now, We can simplify as;

⇒ 2 × 4/6

⇒ 8/6

⇒ 4 / 3

Thus, The value of set of models is equivalent to the expression 2 x 4/6 is,

Answer:

49[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

I'm going to assume the number on the right side of the equation is 5.5, just to make things easier.

Now, to begin to solve this, first isolate the variable.

1/8y - 2/3 = 5 1/2

We do this by adding 2/3 to both sides.

1/8y = 5 1/2 + 2/3

Now, we just wipe off the coefficient that is stuck to the variable by dividing both sides by 1/8, which can be easier done by multiplying by the reciprocal (I converted the mixed number into an improper fraction before solving to facilitate the process).

y = (37/6) · 8

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

Answer:

B will the correct answer.

Step-by-step explanation:

1/2 + 2/3 = 7/6 = 1 1/6

1/3 + 1/8 = 11/24

3/4 + 3/5 = 27/20 = 1 7/20

4/5 + 7/10 = 15/10 = 1 1/2

1 1/6 > 1

11/24 > 1

1 7/20 > 1

1 1/2 > 1

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.

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

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
