Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is \$100$100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for \$25$25 off the repair cost and the other coupon is for 20\%20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20\%20% off the repair cost coupon first. She then uses the \$25$25 off the repair cost coupon on the remaining balance. Natasha uses the \$25$25 off the repair cost coupon first. She then uses the 20\%20% off the repair cost coupon on the remaining balance.

Answer:

32,322,237 million or 3.23million

Step-by-step explanation:

Nevada has the fastest-growing population according to the U.S. Census bureau. In 2004, the population of Nevada was 2.62 million and increasing at an annual rate of 3.5%. What is the expected population in 2010? Apply the population growth formula N=Noe^rt

Applying the formula given above

N=Noe^rt

No = 2.62 million

r = 3.5% = 0.035

t = 2010 - 2004 = 6 years

N = 2.62 × e^6 × 0.035

N = 3.2322365171 million

= 32,322,237 millon

Approximately = 3.23 millon

The volume of the cone is 1592.6 cm³

Volume is defined as the space occupied within the boundaries of an object in three-dimensional space. It is also known as the capacity of the object.

The right circular cone's vertex is immediately above the base's centre. The line connecting the vertex with the centre point of the base is perpendicular to the cone's radius. A cone, on the other hand, can have its vertex anywhere.

Given that, a right circular cone with the height of 19.4 cm and a base with a diameter of 9.9 cm. we need to find the volume,

Volume of cone = 1/3 × π × radius² × height

= 1/3 × 3.14 × (9.9/2)² × 19.4

= 1592.6 cm³

Hence, the volume of the cone is 1592.6 cm³

Answer:

12

Step-by-step explanation:

The Pythagorean theorem is

a^2+b^2 = c^2  where a and b are the sides and c is the hypotenuse ( the side opposite the right angle)

a^2 + b^2 = c^2

Substitute the known values

5^2 + b^2 = 13^2

25+b^2 = 169

Subtract 25 from each side

25+b^2-25 =169-25

b^2 = 144

Take the square root of each side

sqrt(b^2) = sqrt(144)

b=12

Answer:

Given:

To find:

missing side b

Solution:

Using Pythagorean theorem,

(Hypotenuse² = base² + perpendicular²)

b² = c² - a²

= 13² - 5²

= 169 - 25

= 144

b = √144

= 12

Answer:

Ben will roll an even number about 560 times if the number cube is rolled 1,000 times.

Answer:

H = .298

Step-by-step explanation:

First lets plug in 1.5 for R and  16 for Surface area to get the following

2*pi*1.5^2+2*pi*h = 16  We are solving for H or height

Lets simplify this out a bit to get

16 = 14.13+6.28h

Subtract 14.13 from both sides

1.87 = 6.28h

h= .298

To check our answer lets plug the height into the equation

2*pi*1.5^2+2*pi*.298 = 16

Yes the height or H is .298

To check your answer just plug back what you got before into the equation

Answer:

Brittany is 15 years old

Step-by-step explanation:

The way we get the answer is by getting the age of Alyssa 45-15=30 as, Jazmin is 15 years older than Alyssa and then we can see that Alyssa is twice as old as Brittany so we divide Alyssa's age by two. 30÷2=15 and we get Brittany's age which is 15 years old.

Answer:

360°

explanation:

the sum of interior angles of all quadrilaterals (polygons with four sides) is 360°. If you put a pen at any of the four corners and try to draw a line to any other corner, you'll find you can only make two triangles. And since the angle sum of triangles is 180°, 180 times 2 = 360

Answer:

27.5%

Step-by-step explanation:

Hi!

To do this problem, we have to set up a percent proportion:

[tex]\frac{3.3\\}{x}[/tex] = [tex]\frac{12}{100}[/tex]

In this problem, the denominators are the percent values and the numerators are the numerical value.

x = [tex]\frac{3.3*100}{12}[/tex]

x = [tex]\frac{330}{12}[/tex]

x = 27.5%

the solution of the Awnser is (x | x>2)

Step-by-step explanation:

Let's solve your inequality step-by-step.

5x+7>17

Step 1: Subtract 7 from both sides.

5x+7−7>17−7

5x>10

Step 2: Divide both sides by 5.

5x5>105

x>2

y < -12

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−2y − 8 > 16

Step 2: Add 8 to both sides.

−2y − 8 + 8 > 16 + 8

−2y > 24

Step 3: Divide both sides by -2.

−2y/−2 > 24/−2

y < −12

Answer:

y < −12

Step-by-step explanation:

                                                     −2(y + 4) > 16      

                                                               ↓

                                                      −2y − 8 > 16

Answer:

area of shaded portion = 226.09 m²

Step-by-step explanation:

area of circle = πr² = (3.14)(18.6²) = 1086.314 m²

area of 123° segment = (123/360)(1086.314) = 371.157 m²

cos 61.5° = height/18.6 = 8.875

height of triangle = 8.875 m

sin 61.5° = 1/2base/18.6 = 16.346,   base = 32.692 m

base of triangle = 32.692 m

area of triangle = 1/2bh = 1/2(8.875)(32.692) = 145.071 m²

area of shaded portion = 371.157 - 145.071 = 226.09 m²

Answer:

We know that Kant's sister has 150 red marbles and 360 pink marbles.

She separates the marbles in rows, such that each row must have the same number of marbles.

The least number of rows she can make is when she puts N marbles in each row, such that N is the greatest common factor between 150 and 360.

To find the greatest common factor between 150 and 360 we can write them as the product of prime numbers.

150 = 15*10 = (3*5)*(2*5)

360 = 36*10 = (6*6)*(2*5) = (2*3*2*3)*(2*5)

Here we can see that the factors: 2, 3, and 5 appear (at least) one time in each number, this means that the greatest common factor between 150 and 360 is the product of these 3 factors:

GCF = 2*3*5 = 30

This means that we need to make rows with 30 marbles each.

and we will have:

150/30 = 5 rows of red marbles

360/30 = 12 rows of pink marbles.

A total of 5 + 12 = 17 rows.

Answer:

Slope = 3

Y-intercept = -2

Step-by-step explanation:

Points on the line: (0, -2) and (1,1)

Slope:

m=(y2-y1)/(x2-x1)

m=(1+2)/(1-0)

m= 3/1

m = 3

Slope-intercept:

y - y1 = m(x - x1)

y + 2 = 3(x - 0)

y + 2 = 3x

y = 3x - 2

y = mx + b, where

m = slope

b = y-intercept

Answer:

she has a total of 216 inches of ribbon

Step-by-step explanation:

1 foot is equal to 12 inches.

if she has 3 feet per ribbon, and each foot is 12 inches, then 3 × 12 would be 36, making each ribbon 36 inches.

But, she has 6 pieces of ribbon, so that's 36 inches 6 times. 6 × 36 is 216, so she has a total of 216 inches of ribbon.

Answer:

y - 2 = (-1/4)(x - 8)

Step-by-step explanation:

The slope of the given line is 4.  The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.

Use the point-slope formula:

y - k = m(x - h), where (h, k) is the given point.

Then:  y - 2 = (-1/4)(x - 8)
