Answer:

b. 6¹⁰ / 7⁶

Step-by-step explanation:

(6⁵/7³)²

6 × 6 × 6 × 6 × 6 = 7776

7 × 7 × 7 = 343

(7776/343)²

7776²/343²

7776 × 7776 = <u>60.466.176</u>

343 × 343 = <u>117.649</u>

6¹⁰/7⁶

6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 × 6 = 60.466.176

7 × 7 × 7 × 7 × 7 × 7 = 117.649

6¹⁰ = 7776²

7⁶ = 343²

= <u>b</u><u>.</u><u> 6¹⁰ / 7⁶</u>

If a store had 330 video games, and 47% of the games were for Xbox, and 53% were for ps4, then how many xbox and ps4 games are i
Bingel [31]

Answer:

The number of games for Xbox is about 155

The number of games for PS4 is about 175

Step-by-step explanation:

Let us find the numbers of games for Xbox and for PS4 game

∵ There are 330 video games in the store

∵ 47% of them were for Xbox

- Multiply 47% by 330

∴ The number of games for Xbox = 47% × 330

∵ 47% = \frac{47}{100}

∴ The number of games for Xbox = \frac{47}{100} × 330

∴ The number of games for Xbox = 155. 1

∴ The number of games for Xbox ≅ 155

∵ 53% of them were for PS4

- Multiply 53% by 330

∴ The number of games for PS4 = 53% × 330

∵ 53% = \frac{53}{100}

∴ The number of games for PS4 = \frac{53}{100} × 330

∴ The number of games for PS4 = 174.9

∴ The number of games for PS4 ≅ 175

Which equation represents a line that has a slope of 1/3 and passes through point -2, one
tensa zangetsu [6.8K]

Answer: y= 1/3 x + 5/3

Step-by-step explanation:

1= 1/3(-2) + b where b is the y intercept

  1=   -2/3 + B

+2/3   +2/3

B = 5/3

so we know the slope and the y- intercept

y= 1/3x + 5/3   check:   1=1/3(-2) +5/3

                                    1 =1

A rectangle has length 127.3 cm and width 86.5 cm, both correct to 1 decimal place. Calculate the upperbound and the lowerbound
Mnenie [13.5K]

Answer:

Correct to 1dp

127.3 cm = 127.0 cm

86.5 cm = 87.0 cm

Upper limits:

127.0 cm = 127.05 cm

87.0 cm = 87.05 cm

Lower Limits:

127.0 cm = 126.95 cm

87.0 cm = 86.95 cm

upper limit of perimeter of rectangle:

P = 2(l+w)

= 2(127.05 + 87.05)

= 2(214.1)

= 428.2 cm

lower limit of perimeter of rectangle:

P = 2(l+w)

= 2(126.95 + 86.95)

= 2(213.9)

= 427.8 cm

therefore;

427.8 cm \leqslant perimeter < 428.2cm
