Answer:

1. About 9 left. 2. £21 left

Step-by-step explanation:

First, you do 65 ÷ 3 = 21.7 if rounding to the tenths, 21.67 if to the hundredths, and so on. Then you do 21.67 - 12 = 9.67. But since it is cards, I would say about 9 left.

First you add the £20 to the £70 to get £90. then you multiply 7×3 to get £21 spent on books. After that, multiply 12×4 to get £48 spent on games. then do 48 + 21 = 69. 90-69= 21.

Here is the equation....

(70+20)-[(7×3)+(12×4)] = £21

25m + 100 - 24m - 75 = 68.
Maksim231197 [3]

25m+100−24m−75=68

Step 1: Simplify both sides of the equation.

25m+100−24m−75=68

25m+100+−24m+−75=68

(25m+−24m)+(100+−75)=68(Combine Like Terms)

m+25=68

m+25=68

Step 2: Subtract 25 from both sides.

m+25−25=68−25

m=43

Answer:

m=43

Gary has 7 suits. In how many different ways can he arrange the suits in his wardrobe?
Svet_ta [14]
If Gary has seven suits, he can choose which of the seven he will place first. He can choose from the remaining six which one he will place next. This goes on until all the suits are placed in his wardrobe. In short, he can arrange his suits in 7! (7 factorial) ways in his wardrobe. 
 
                                  7! = 5040

Thus, Gary can arrange his suits in 5040 ways.

50 POINTS!! Drag each label to the correct location on the image. Not all labels will be used. The values of a, b, and c in scie
serg [7]

Answer:

\boxed{a*b = 1.60 * 10^2}

\boxed{a/b = 7.53 * 10^{-14}}

\boxed{c/a = 1.59 * 10^{13}}

Step-by-step explanation:

a = 3.47 * 10^{-6}

b = 4.61 * 10^7

c = 5.52*10^7

<u><em>Finding a*b:</em></u>

a*b =( 3.47 * 10^{-6} )*( 4.61 * 10^7)

= (3.47*4.61) * (10^{-6}*10^7)

When bases are same, powers are to be added

= 15.997 * 10^{-6+7}

= 15.997 * 10^1

= 159.97

Rounding it off

=> 1.60 * 10²

<u><em>Finding a/b:</em></u>

=> \frac{3.47*10^{-6}}{4.61*10^7}

Using rule of exponents a^m/a^n = a^{m-n}

=> 0.753 * 10^{-6-7}

=> 7.53*10^{-1}*10^{-13}

=> 7.53 * 10^{-1-13}

=> 7.53 * 10⁻¹⁴

<u><em>Finding c/a:</em></u>

=> \frac{5.52 * 10^7}{3.47*10^{-6}}

=> 1.59 * 10^{7+6}

=> 1.59 * 10¹³
