1.

= 84 / 3 = 28

= 2 * 28 = 56

= 1 * 28 = 28

2.

280 / 8 = 35

= 3 * 35 = 105

= 5 * 35 = 175

3.

2100 / 7 = 300

= 4 * 300 = 1200

= 3 * 300 = 900

4.

420 / 6 = 70

= 1 * 70 = 70

= 2 * 70 = 140

= 3 * 70 = 210

5.

360/8 = 45

45 * 5 = 225

45 * 1 = 45

45 * 2 = 90

6.

1000 / 25 = 125

jenny = 125 x 5 = 625

chris = 125 x 3 = 375

7.

3000 / 10 = 300

fred = 7 * 300 = 2100

freda = 3 * 300 = 900

Daniel and Edwin went to lunch. Daniel’s meal cost $20 and Edwin’s meal cost $18.50. They each left an 18% tip on the price of t
Neporo4naja [7]

Answer:

$45.43

Step-by-step explanation:

20 × 0.18 = 3.60

18.50 × 0.18 = 3.33

3.60 + 3.33 = 6.93

The total in tips is 6.93

20 + 18.50 = 38.50

The total meal cost is 38.50

38.50 + 6.93 = 45.43

The total of everything is 45.43

Zoe and Hannah share tips in the ratio 3:7. Last week, Zoe received £24. How much did Hannah receive last week?​
frozen [14]

Answer:

56

Step-by-step explanation:

If the ratio of Zoe; Hannah is 3:7 and Zoe got 24 than we have to divide the 24 by 3 so we can multiply it by 7. This is because since the Zoe is the 3 and it isn't a 1 it isn't the starting point for either of the ratios we cannot multiply the 24 by 7.

24 ÷ 3 = 8

Now we multiply the 8 by 7 so that we know have many tips Hannah made

8 × 7 = 56

Hannah made 56 in tips

Your friend claims that if a line has a slope less than 1, then any line perpendicular to it must have a positive slope. Is your
mezya [45]

Answer:

The friend's claim is not correct

Step-by-step explanation:

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)

Example

A given line has a slope of m_1=1/2  ---> (is less than 1)

the slope of the line perpendicular to the given line is equal to

m_1*m_2=-1

substitute

(1/2)*m_2=-1

m_2=-2

so

the perpendicular line don't have a positive slope

therefore

The friend's claim is not correct
