During a record setting rainfall, 0.057 inch of rain fell every
minute for 35 minutes. How much rain fell in 10 minutes?

14.23n - 15 = 41.92

Explanation :

In mathematics "n" denotes any non-negative integer

as in this case "n" denotes the number of necklaces Christine bought

If 1 necklace costs $14.23

n no. of necklaces costs $14.23 × n = 14.23n

She used a coupon for $15 off

so the total amount spent

= the cost for n no. of necklace – $15

= 14.23n – 15

that's technically how the equation given in the question has been derived

total amount spent = $41.92 ( stated in question )

previously we derived an equation for the total amount spent which is = 14.23n – 15

14.23n - 15 = 41.92

14.23n = 41.92 + 15

14.23n = 56.92

n = 56.92 / 14.23

n = 4

no. of necklaces bought = n = 4 necklaces

hope this helped :)

Answer:

y-intercept is 3

The point where the line intercepts the y-axis is (0, 3)

Step-by-step explanation:

Slope-intercept form of a linear equation:  [tex]y=mx+b[/tex]

(where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept)

Given equation of line:  [tex]y=3-4x[/tex]

Rearrange:  [tex]y=-4x+3[/tex]

Therefore, the slope of the line is -4 and the y-intercept is 3.

FYI the line intercepts the y-axis when x = 0, so you can input x = 0 into the equation to find y ⇒ (0, 3)

Answer:

The y-intercept of the line is 3.

Step-by-step explanation:

Formula: y = mx + b

y = 3 - 4x

y = -4x + 3

On the formula, "b" means y-intercept. Therefore, the y-intercept of the line is 3.

Answer:

22.608 units

Step-by-step explanation:

Basically, the circumference of a circle is the distance around a circle, sort of like the perimeter of a figure. It has a unique formula which is [tex]C=2\pi r[/tex] where [tex]r[/tex] is the radius, which is the distance between the circle and its center. Using our given information, we can find the circumference:

[tex]C=2\pi r\\C=2(3.14)(3.6)\\C=22.608[/tex]

Therefore, the circumference of a circle with a radius of 3.6 units is 22.608 units.

Answer:

Circumference is...

Step-by-step explanation:

Multiply the radius by 2 to get the diameter.

Multiply the result by π, or 3.14 for an estimation.

That's it; you found the circumference of the circle.

Answer:

62

Step-by-step explanation:

step 1: find the height of half the yellow coloured triangle (right angled triangle). remember that the angle formed at the center is always 36° for a pentagon.

tan36° = opposite/ adjacent

tan36° = 3/h (h for height)

h × ( tan36°) = 3

h = 3 / tan36°

h = 4.13

step 2: calculate area of the right angled triangle

Area = 1/2 × b × h

= 1/2 × 3 × 4.13

= 6.195

step 3: calculate the area of a Pentagon

a Pentagon can be divided into ten right angled

triangle

6.195 × 10

total area = 61.95

rounded off = 62

Answer:

Volume for a cylinder in this case is

V=˜ πr^2h

So R being radius

H being height

V being volume.

We know the volume is 250π

The height is given in the diagram which is 10.

Plug in the infromation into the formula.

250π = πr^2*10

Simplify and solve for r (radius).

Let’s divide by π on both sides

250 = r^2 * 10

Divide by 10 to get rid of 10

25 = r^2

√25 = r

√25 = 5

The radius is 5

Answer:

4x

Step-by-step explanation:

x hours for 4 weeks = 4x

it's 4 times x

Step-by-step explanation:

Solve the problem step by step.

First,

Base area: 6 * 2.5 = 15

Then,

The area of the two smallersides:

2.5 * 4 = 10

10 * 2 = 20

After that,

The area of the two larger sides:

6 * 4 = 24

24 * 2 = 48

After all of the calculations, you add all of the sums up:

15+20+48

Which equals 83.

The equation form for this problem would be:

(6*2.5) + 2(2.5*4) + 2(6*4) = 83

Hope this helps and it wasn't too confusing!

Step-by-step explanation:

=> 3⁵÷3⁷

Note 3⁵ means multiplying 3 five times

And 3⁷ means multiplying 3 7 times

=> 3×3×3×3×3÷3×3×3×3×3×3×3

multiply the values and then divide

=> 243÷2,187

divide 243 by 2187

=> 0.111111111111111

The difference in the price per bag for 150 bags versus 50 bags is $0.15 per bag.

If 150 bags on the x axis is traced to the y axis, the price of the bag is $38.

If 50 bags on the x axis is traced to the y axis, the price of the bag is $20.

Price per bag:

150 bags = 38 / 150 = $0.25

50 bags = $20 / 50 = $0.4

The difference = $0.4  $0.25 = $0.15

Answer:

$57

Step-by-step explanation:

I'll assume the pool's dimensions are 18 x 40 x 6.

The total volume is (18 x 40 x 6) = 4320 ft^3.

Use the conversion factor (2.64 gallons/1 ft^3) to find the gallons of water in a full pool.  Full pool, cool.

Water (gal) = (4320 ft^3)*(2.64gallons/ft^3) = 11,405 gallons

At $0.005/gal, this would cost (11,405 gallons)*($0.005/gal) = $57.02

$57 to the nearest dollar.

Hopes this helps!

Step-by-step explanation:

look at a die, for example.

the probabilty to roll a 6 is 1/6 (if all numbers truly have the same probability due to a perfectly balanced die).

so, you expect as a mean value that you have to roll the die 6 times to get one 6.

now in our general example :

20% = 1/5

so, we expect event A to happen once as a mean value every 5 attempts.

now we do 40 attempts. that means 8×5 sets of attempts.

and we therefore expect to see event A 8 times.

Answer:

Depends on the pool you are pulling them from.

There are currently 11 different denomination accessible.

That would be 1 out of 11.

But considering that 4 of those bills are uncommon, the odds become 1 out of 7

Then to pull 2 of the same would mean you multiply 1/11 by 1/11 = 1/121

for the 1/7 it would become 1/49
