Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $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 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.

Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.

Natasha uses the $25 off the repair cost coupon first. She then uses the 20% off the repair cost coupon on the remaining balance.

Which of the following is a factor of 21?

Answers

Answer:

The factors of 21 are 1, 3, 7 and 21. A factor is a number that can divide evenly into a given number. Because 21 can be divided by numbers other than itself and 1, it is called a composite number. Every number has 1 and itself as a factor. Numbers that have no other factors are called prime numbers.

Complete the equation of this circle:
(x - [ ? ])2+(y - [ ])2= []

Answers

The complete equation of the circle graphed is (x - 2)² + (y + 2)² = 9

Determining the equation of the circle graphed

From the question, we have the following parameters that can be used in our computation:

The circle

Where, we have

Center = (a, b) = (2, -2)

Radius, r = 3 units

The equation of the circle graphed is represented as

(x - a)² + (y - b)² = r²

So, we have

(x - 2)² + (y + 2)² = 3²

Evaluate

(x - 2)² + (y + 2)² = 9

Hence, the equation is (x - 2)² + (y + 2)² = 9

An object is thrown straight up from the top of a building h feet tall with an initial velocity of v feet per second. The height of the object as a function of time can be modeled by the function h(t) = –16t2 + vt + h, where h(t) is the height of the object (in feet) t seconds after it is thrown.

Step-by-step explanation:

A ball is thrown straight up from the top of a 128 foot tall building with an initial speed of 32 feet per second. The height of the ball as a function of time can be modeled by the function h(t) = –16t2 + 32t + 128. How long will it take for the ball to hit the ground?

Steven needed to mail a holiday envelope to his Aunt Linda. He used $0.02 stamps and $0.10 stamps to mail the gift. If he used 15 stamps worth $0.78, how many of each type of stamp did he use?

Answers

Answer:Steven used 9 $0.02 stamps and 6 $0.10 stamps

Step-by-step explanation:

let number of $0.02 stamp be =x

let number of $0.10 stamp be =y

so that the number of stamps used can be expressed as

x+y=15

and the total price of stamps used equaling $0.78 be expressed as

0.02x + 0.10y =0.78

Solving

x+y=15----1

0.02x + 0.10y =0.78---2

from equation 1 , x =15-y, putting the value of x into equation 2

0.02(15-y) + 0.10y =0.78

0.3 -0.02y + 0.10y = 0.78

0.3 + 0.08y=0.78

0.08y=0.78-0.3

y=0.48/0.08 =6

y =6 stamps

Putting bthe value of y =6 into equation 1

x+6=15

x=15-6 =9

Steven used 9 $0.02 stamps and 6 $0.10 stamps

Dairy cows provide 90% of the world's milk supply. The
table shows the amount of milk produced by a cow over
time. If the pattern in the table continues, how much milk
can a farmer get from a cow in 1 year (365 days)?

Answers

Answer:

9,125 L

Step-by-step explanation:

The computation of the milk that can a farmer would get from a cow in one year is shown below:

As in the table it is shown that

In 2 days, the amount of milk is 50 L

In 7 days, the amount of milk is 175

and so on

So if we can see that the number of days should be multiplied by 25 to get the liters

So for 365 days, the milk would be

= 365 days × 25

= 9,125 L

PLEASE HELP ASAP!!

Answers

SO you would have to first have the surface area of the cube which is 25 for each side so 25 x 6 = 150

Then you find the surface area for the other sides and It is 4 x 5 divided by two for each triangle on the side, so that would be 20 and you multiply then 6.4 x 5 to equal 32 for the rectangle. The last part is the bottom and it is 4 x 5 again which is 20 so then you add them all up but im not sure.

Some scientists seek answers in the depths of the sea. When Georg Steinhauser wanted answers, he looked within himself. Well, he looked within his bellybutton to be exact. The Austrian chemist spent three years researching the contents of his navel and the navels of others. He has solved one of life's greatest mysteries. We now know exactly what bellybutton lint contains!Steinhauser presented his findings in the online version of the journal Medical Hypotheses. The Vienna University scientist analyzed over 500 samples to determine the exact makeup of the lint. As suspected, most of the lint was made up of cotton from clothing. The fabric pieces are not alone, though. Steinhauser found that the average bellybutton also contained pieces of dead skin, sweat, dust, and fat.Steinhauser's notes also explained how lint accumulates. Stomach hairs tend to grow in a circular pattern around the bellybutton. The hairs act like small hooks, capturing and holding contents within. Shaving stomach hair can lead to a lint-free bellybutton, but don't act too hastily. Although the contents of your navel may be a nuisance, research suggests that lint has a purpose. It is nature's way of protecting your bellybutton from germs and unwanted objects. Add Audio Add VideoYou must check the box below prior to submitting your exam!
