Amy received a $80 gift card for a coffee store. She used it in buying some coffee that cost $8.17 per pound. After buying the coffee, she had $55.49 left on her card. How many pounds of coffee did she buy?

Answer:

[tex]\sqrt{16} < \sqrt{17} < \sqrt{18}[/tex]

Step-by-step explanation:

Answer:

[tex]4 < \sqrt{17} < 5[/tex]

Step-by-step explanation:

Mumble. The square root is something called "monotonic", which means that [tex]a > b \Leftrightarrow \sqrt a > \sqrt b[/tex]

A neat trick to solve this will be: go back from 17 till you find a perfect square, then add 1 to it:

In our case it's easy to do it, since the number before 17 is a perfect square already ([tex]16=4^2[/tex]), so we can pick it as the lower bound, and then add 1 to the base to find the next one ([tex]4+1= 5)[/tex]

Answer:

8 cm

Step-by-step explanation:

We first want to draw a diagram with the given information.

I am unsure if the image shows below, or if it is an attachment.

We then see we have a right triangle. What is a theorem that is commonly associated with right triangles?

So we use the pythagorean theorem to find the missing leg of the triangle has a length of 4 cm. But how does this help us? Well, when finding the distance from the center of a circle to a chord, we always find the line that is perpendicular to the chord and divides it in half (and passes through the center), and find the length.

So, the leg of length 4 we just found? That's half of our answer.

Since 4 × 2 = 8, we know that the length of AB is 8 cm.

Answer:

18cm

Explanation

2πr

2×22/7×6=38cm

4l=14×4=56

The difference=56-38=18cm

Answer:

Point H is (1,3)

Step-by-step explanation:

The x co - ordinate lies to the right and the y co-ordinate lies above . We are given  H is 3 units above and 1 unit to the right of the origin  so the co-ordinates of H  are ( 1,3).

As this particular order (x,y) is used to represent the the point it is called ordered pair.

The ordered pairs of the other points are

Point A is (4,5)

Point  C is (5,4)

Point H is (1,3)

Point K is (3,1)

Point N is (2,0)

Answer:

+ 4

Step-by-step explanation:

The pattern of the expression is +4 as you see it goes 5 to 9

5 + 4=9

And if i'm correct the number after 9 will be 13 and it is

9 + 4=13

next it will be a 17 because 13 + 4=17

The next following numbers of the pattern will be 21  25  29  33  37 41 45

Hope it helps have a great day:)

Step-by-step explanation:

Answer:

  A = 72

  B = 16

Step-by-step explanation:

Ratio problems can often be worked by considering them in terms of "ratio units." Here, the difference in ratio units is 9-2 = 7. The difference between the actual numbers is A -B = 56. This means each ratio unit stands for an actual number value of 56/7 = 8

Then the ratio of actual values is ...

  A : B = (9·8) : (2·8) = 72 : 16

Check: These actual values of A and B have a difference of 72-16 = 56.

  (A, B) = (72, 16)

The number of feet a person on the carousel travels in 8 revolutions is 1004.80 feet

The circumference of a circle is the distance round the circle. It is the perimeter of the circle.

circumference of a circle = 2πr

2 x 20 x 3.14 = 125.60 feet

Number of revolutions = 8 x 125.60 feet = 1004.80 feet

Answer:

n = 6 probably

Step-by-step explanation:

10 + I 10n + 6 I+ = 76

since " I   I " means it will always be positive we can kinda just ignore it

10 + 10n + 6 = 76

16 + 10n = 76

10n = 76 - 16

10n = 60

n = 6

3 huts are built by 5 people in 21 days.

So 1 hut is built by 5 people in 7 days.

That is to say, 1 hut requires 5*7 = 35 man-days.

Which means 6 huts need 6*35 = 210 man-days.

If the time available is 15 days, 6 huts will need 210 man-days/15 days = 14 people.

Answer = 14 people.

Answer:

x = 8

Step-by-step explanation:

Since this is a rectangle, we know that each corner's angle is 90 degrees. (The box thing at the bottom right shows this.)

Since the two angles that make up angle E sum up to 90, we can make an equation:

(9x - 6) + (2x + 8) = 90

11x + 2 = 90

11x = 88

x = 8

Answer:

It rained 3/8 cm more on Tuesday than Monday.

Step-by-step explanation:

What I first did is convert the fraction 3/4 into 6/8 (multiply both sides by two) so I could get a common numerator to solve the two fractions. Then, I gave one whole from the 2 wholes in 2 1/8 to 1/8 to make it easy to subtract with 6/8 (I wuldn't like to do 1/8-6-/8) and made it into 9/8. Then it's simple subtraction (oh yes and don't forget to turn the 2 into 1 since it lost a whole) and voila! 3/8 cm

Answer:

43.185

Step-by-step explanation:

43.185.is the upper bound of 43.18 which is corrected to 2 decimal places.

An element greater than or equal to all the elements in a given set

We need to find the upper bound of 43.18 cm correct to 2 decimal places

2 decimal place = 0.01

0.01 ÷ 2 = 0.005

So now add 43.18 and 0.005.

43.18 + 0.005 = 43.185.

Therefore 43.185.is the upper bound of 43.18 correct to 2 decimal places.

Answer:

A) 60 girls B)80 boys

Step-by-step explanation:

Pretend that the ratio is a fraction. If there are 4 boys for every 4 girls, than pretend that you add the 4 and the 3 together, thus giving you 7 as your denominator. Start with the girls, giving you a fraction of 3/7, multiply by 140, you get 60 as the number of girls. 140-60=80, giving you 80 boys.
