Answer:

1: 24 girls

2: 640

3: 300

4: 3/10

5: 42

Step-by-step explanation:

1: 2/5 × 40

80÷ 5

16

girls = 40- 16

= 24

2: 1/3 × 960

960 ÷3

= 320

Left = 960 - 320

= 640

3: 3/8 × 480

1440 ÷ 8

= 180.

Left = 480 - 180

= 300

4: 2/5 × 3/4

= 6/20

= 3/10

5: 2/5 × x = 18

2x = 28 × 5

2x = 140

x = 70

70 - 28

= 42

Calculate JK if LJ=45, JM=60 and LM=75
aliina [53]

Answer:

JK = 20

Step-by-step explanation:

Angle Bisector Theorem: an angle bisector of a triangle divide the opposite side into two segments that are proportional to the other two sides of the triangle

LK / JK = LM / JM

(45 - JK) / JK = 75 / 60 = 5 / 4

5 JK = 4 (45 - JK)

5 JK = 180 - 4 JK

9 JK = 180

JK = 20

Hello!

998 rounded to the nearest 10 is 1000. It is also 1000 when rounded to the nearest 100.

274 rounded to the nearest 10 is 270. 274 rounded to the nearest 100 turns it into 300.

533 to the nearest 10 is 530. It is 500 when rounded to the nearest 100.

I hope this helps you!

How do you Estimate the Product of Decimals and Whole
PtichkaEL [24]

Answer:

1) 8.5

2) 60

3) 69.3

4) 6.8

5) 3.6

6) 10.5

Step-by-step explanation:

Take out the decimal of the estimated factors and multiply. Count how far to left the decimal is in the factors. In the product, put the decimal as many to the left as it was in the factors. (ex. 6.93 x 42, 6.93 rounds to 6.9, 42 rounds to 40, 69 x 40 = 2,760, move the decimal over one for correct place value,            6.9 x 40 = 276.0 <em>or </em>276)
