Answer:

22 cards

Step-by-step explanation:

Set up a ratio.

[tex]\frac{34}{29+x} =\frac{2}{3}[/tex]

[tex]58+2x=102[/tex]

[tex]2x=44[/tex]

[tex]x=22[/tex]

Check: Add 22 to 39. 22+29=51

34/51 = 2/3

Have a great day

Answer:

c

Step-by-step explanation:

If a piece is equal to 1/10 of a pan , a pan would make 10 brownies

5 pans would make , 10 x 5 = 50 brownies

Answer: c

Step-by-step explanation: each pan is 10 slices so if you multiply that with how many pans you have which is 5 and 5 x 10 = 50

Answer: [tex]2\sqrt{22}[/tex]

Step-by-step explanation:

Pythagorean theorem: [tex]a^{2} +b^{2} = c^{2}[/tex], where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

[tex]9^{2} +b^{2} = 13^{2}[/tex]

[tex]81 +b^{2} = 169[/tex]

Since we don't know what [tex]b^{2}[/tex] is, we're going to isolate it by subtracting 81 on both sides

[tex]b^{2} = 88[/tex]

We have to square root both sides in order to find out b (or x in the problem).

[tex]\sqrt{b^{2}} = \sqrt{88}[/tex]

When you put this on a calculator it would result in [tex]2\sqrt{22}[/tex] which is the answer d in the problem.

Answer:

1. 37.5 metres.

2. 33.33 metres (May be wrong due to the answer but I used the correct solution to find the answer)

3. Refer to explanation.

Step-by-step explanation:

1. Find out how much Logan and Mila both swam.

1/3 of an hour =

60 minutes ÷ 3 = 20 minutes

Logan swam 750 metres for 20 minutes.

Mila swam 2/3 of Logan's distance.

Find out how much is 1/3 of Logan's distance in 1/4 of an hour.

3/3 = 750

1/3 = 750 ÷ 3 = 250

2/3 = 250 x 2 = 500

1/4 of an hour =

60 minutes ÷ 4 = 15 minutes

Mila swam 500 metres in 15 minutes.

To find out Logan's average swimming speed, here's the formula:

Total distance/total elapsed time

So it is 750/20 which is 37.5 metres.

2. Use the same formula I mentioned above in question 1 for average swimming speed, so it is...

500/15 = 33.33 metres

3. Other ways to compare Mila's and Logan's swimming speed is to find out the difference of the distance of how long they swam.

Use Mila's average swimming speed and find out how much metres she would swim if she swam for 20 minutes.

33.33 metres x 20 minutes = 666.6 metres

Answer:

The 2nd option:

1.339×10⁶

Step-by-step explanation:

To find the combined capacity, add the two values together so:

(8.12×10⁵ ) + ( 5.27 × 10⁵ )

It will be simpler to add if you change it out of its

standard form

812000+527000

= 1339000

Now you can write in back in standard form, which will be

1.339×10⁶

Answer:

18 children

Step-by-step explanation:

The computation of the more children went to scotland is as follows:

Given that

There is 200 children

out of which 18% went to wales i.e. = 200 × 18% = 36

And, 27% went to scotland i.e. = 200 × 27% = 54

So, the more children went to scotland is

= 54 - 36

= 18 children

Answer:

2k/5 + 1 + -k+1/3

Step-by-step explanation:

(2k - 7)/5  + 1 - 1 x (k - 1)/3

Simplify

Combine multiplied terms into a single fraction

2k - 7/5 + 1 - 1 x  k - 1/3

2k- 7/5 + 1 + -1(k - 1)/3

Distribute

2k - 7/5 + 1 + -1(k - 1)/ 3

2k - 7/5 + 1 + = -k + 1/3

Solution

2k - 7/5  + 1 +   -k + 1/3

Answer:

[tex]\frac{k-1}{15}[/tex]

Step-by-step explanation:

[tex]\frac{(2k - 7)}{5} + 1 - \frac{(k-1)}{3}[/tex]

[tex]\frac{3(2k -7)}{3 ( 5)} + \frac{15 * 1}{15 * 1} - \frac{5(k-1)}{5 * 3}[/tex]

[tex]\frac{6k - 21}{15} + \frac{15}{15} - \frac{5k - 5}{15}[/tex]

[tex]\frac{(6k - 21) + 15 - (5k - 5)}{15}[/tex]

[tex]\frac{(6k - 6) - (5k - 5)}{15}[/tex]

[tex]\frac{6k - 6 - 5k + 5}{15}[/tex]

[tex]\frac{k - 1}{15}[/tex]         <------This is your answer

Answer:

D

Step-by-step explanation:

D, it has a right angle and it shows us that the hypotenuse is congruent and the leg is also congruent.

Answer:

a3 + b3 = -7

Step-by-step explanation:

When the sequence is A.P

a1 =4 and a2= -2

Common difference,d = a2 - a1

= -2 - 4

d = -6

a3 = third term

a3 = a1 + 2d

= 4 + 2(-6)

= 4 - 12

= -8

a3 = -8

When the sequence is geometric

a1 =4 and a2= -2

Common ratio, r = a2/a1

= -2/4

r = -1/2

Or

r = -0.5

b3 = third term

b3 = ar²

= 4 * (-1/2)²

= 4 * 1/4

= 4/4

= 1

b3 = 1

a3 + b3 = -8 + 1

= -7

a3 + b3 = -7

Answer:

(x - 43)(x + 43)

Step-by-step explanation:

x² - 43² ← is a difference of squares and factorises in general as

a² - b² = (a - b)(a + b), then

x² - 43²

= (x - 43)(x + 43)

Answer:

(x - 43)(x + 43).

Step-by-step explanation:

This is the difference of 2 squares:

a^2 - b^2 = (a - b)(a + b) so here we have:

x^2 - 43^2 = (x - 43)(x + 43).
