What is the area of the circle 24m

Answer: 40 cm.

Step-by-step explanation: Perimeter involves adding all the sides of a shape to get the perimeter.  So far, two sides of the scrapbook have been given, which are both 37 cm.  37 x 2 = 74, so that leaves us with two sides left, which are the lengths of the scrapbook.  The total perimeter is 154, so if we subtract 74 from 154, we get 80.  However, we have to split the 80 in half because we have two sides left.  Therefore, the scrapbook's length is 40 cm for one side.  I hope this isn't too confusing.

Have a great day! :)

Answer:

  350 adult tickets

Step-by-step explanation:

If x is the number of adult tickets sold, then x-57 is the number of student tickets sold (57 fewer). The total number sold is ...

  x +(x -57) = 643

  2x = 700 . . . . . . . . collect terms, add 57

  x = 350 . . . . . . . divide by 2

There were 350 adult tickets sold.

Answer:

B

Step-by-step explanation:

It's 18! Obviously it's not 180 because it's too big. It can't be 36 because 36 doesn't go evenly into 90. 6 is too small, so the answer is 18.

Answer:

There are 8 oz of soup per can  :  True

In 8 cans, there are 21 oz of soup  : False

There are 2 oz of soup in 16 cans  : False

In 1/8 of a can, there is 1 oz of soup  : True

Step-by-step explanation:

To start, we know we have 168 oz of soup and 21 cans that are all the same size. To find how much is each can, (We know that they will all have the same amount since it says equally sized cans.) we can simply divide the amount we have of soup in oz by the amount of cans we have.

168 / 21 = 8.

This means that all the cans will be filled with 8 oz of soup. Making the first statement true.

Since there are 8 oz in each can, we can do 8 cans * 8 oz to find how many oz are in 8 cans of soup.

8 * 8 = 64 oz.

There are 64 oz of soup in 8 cans. Making the second statement false.

Now again, since there are 8 oz in each can, we can do 16 cans * 8 oz to find how many oz are in 16 cans of soup.

16 * 8 = 128 oz.

There are 128 oz of soup in 16 cans. Making the third statement false.

For the last question, to find 1/8 of a can of soup, we can take 8 oz (8 oz in one can) and divide it by 8.

8/8 = 1

Meaning 1/8 of a can of soup is 1 oz of soup. Making the fourth statement true.

Answer:

-Dilate circle A by scale factor of 2

Got it right on the test (see picture)

Circle A is translated using the rule (x + 1, y - 1). Then the correct option is B.

It is a locus of a point drawn an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Circle A has a center of (2,3) and a radius of 5, and circle B has a center of (1,4) and a radius of 10.

Circle B is translated as 1 unit leftward in the x-direction and 1 unit upward in the y-direction.

Then circle B is dilated by a factor of 2.

A -- She saves 200₤.

B -- She will have 28₤ after buying presents.

Step-by-step explanation:

If two boxes = 20 then one box will be 10. Now we count all boxes. There are 20 boxes... 20 x 10 = 200, so she saves 200₤. If she spends 172₤ on Christmas presents she will have 28₤. (200 - 172 = 28).

Answer:

15 years old

Step-by-step explanation:

Start by defining the variables that we are going to use throughout our working:

Let the current age of Wei Ling and Wei Xuan be L and X years old respectively.

Next, form equations using the given information.

5 years ago

Wei Ling: (L -5) years old

Wei Xuan: (X -5) years old

Given that the ratio of Wei Ling's age to that of Wei Xuan's is 2: 5,

[tex] \frac{ L - 5}{X - 5} = \frac{2}{5} [/tex]

Cross multiply:

2(X -5)= 5(L -5)

Expand:

2X -10= 5L -25

2X= 5L -25 +10

2X= 5L -15 -----(1)

9 years time

Wei Ling: (L +9) years old

Wei Xuan: (X +9) years old

Given that the ratio of Wei Ling's age to that of Wei Xuan is 3: 4,

[tex] \frac{L + 9}{X + 9} = \frac{3}{4} [/tex]

Cross multiply:

3(X +9)= 4(L +9)

Expand:

3X +27= 4L +36

3X= 4L +36 -27

3X= 4L +9 -----(2)

Let's solve using the elimination method.

(1) ×3:

6X= 15L -45 -----(3)

(2) ×2:

6X= 8L +18 -----(4)

(3) -(4):

6X -6X= 15L -45 -(8L +18)

0= 15L -45 -8L -18

0= 7L -63

7L= 63

L= 63 ÷7

L= 9

Substitute L= 9 into (1):

2X= 5(9) -15

2X= 45 -15

2X= 30

X= 30 ÷2

X= 15

Thus, Wei Xuan is 15 years old now.

Answer:

45.27 miles

Step-by-step explanation:

Pythagorean theorem

23^2 + 39^2 = d ^ 2

d = 45.27 miles

If  a person drives 23 miles south and make a turn to east and drive 39 miles then the distance between starting point and person is 45.27 miles.

Pythagoras theorem applies in a right angled triangle. It says that in a right angled triangle the square of hypotenuse is equal to sum of squares of perpendicular and base of that triangle.

[tex]H^{2} =P^{2} +B^{2}[/tex]

When person drives towards south and then east , it forms a right angled triangle. We have to find the distance of person from the starting point. If we see the figure then we will come to know that we are require to find hypotenuse of triangle.

H=[tex]\sqrt{P^{2} +B^{2} }[/tex]

Distance=[tex]\sqrt{23^{2} +39^{2} }[/tex]

=[tex]\sqrt{1521+529}[/tex]

=[tex]\sqrt{2050}[/tex]

=45.27

Hence the distance of person from starting point is 45.27 miles.

By applying the Newton's law of cooling and performing the neccessary calculations, the time of death of the body is about 4 hours ago.

According to the Newton's law of cooling;

T(t) = T(s) + (To - Ts)e^-kt

T(t) = temperature at time t

T(s) = temperature of the surroundings

To = Initial temperature

k = cooling constant

t = time taken

Substituting the values;

T(t) = 60 + (98.6 - 60)e^- 0.1947t

To find the time taken to attian a temperature of 78°F;

78 = 60  + (98.6 - 60)e^- 0.1947t

78= 60 + 38.6e^- 0.1947t

78 - 60 = 38.6e^- 0.1947t

18/38.6 = e^- 0.1947t

0.466 = e^- 0.1947t

ln0.466 = lne^- 0.1947t

ln0.466 =- 0.1947t

t = ln0.466 /- 0.1947

An additional interest of $ 4.08 is earned in year 5 by using compound interest and in comparison with simple interest method.

Simple interest (C) is the amount of money gained and solely related to the initial capital ([tex]C_{o}[/tex]), in monetary units. The money earned by simple interest is determined by the following formula:

[tex]C = \frac{C_{o}\cdot r\cdot t}{100}[/tex]     (1)

Where:

Compound interest (C) takes into account the capital throughout time and its formula is presented below:

[tex]C = C_{o}\cdot \left[\left(1+\frac{r}{100} \right)^{t}-1\right][/tex]

Now we proceed to determine the simple and compound interest: ([tex]C_{o} = 1000[/tex], r = 2, t = 5)

C = [(1000) · (2) · (5)]/100

C = $ 100

C = (1000) · {[1+(2/100)]⁵-1}

C = $ 104.08
