Answer:

1. m∠B=110°

2. 560 cm3

3. Numerical data

4. 2000 cm3

5. 50%

Step-by-step explanation:

1. The explanation of part 1 is given in the attachment.

2. Given dimensions : 10 cm, 8 cm, and 7 cm.

Let Length of cuboid =10 cm

breadth/width of cuboid =8 cm

height of cuboid = 7cm

Volume of cuboid = length *width* height

=( 10 *8*7) cm3

=(560) cm3

3. Age, Birth date and weight are the types/examples of "Numerical Data" because these all are describe in terms of numeric values.

4. 1 liter = 1000 cm3 or 1 cm3 = 0.001 liter

1.5 liters =(1.5*1000) cm3 = (15*100) =1500 cm3

1 dm3 =1000 cm3

0.35 dm3 = (0.35*1000) cm3 = (35*10) cm3 =350 cm3

Given expression: 1.5 litre + 0.35 dm3 + 150 cm3 = cm3

1500 cm3 + 350 cm3 +150 cm3 = 2000 cm3

5. If A=(1/2)B, then B : A = 50 %

Ratio: B : A

B : (1/2) B

1: (1/2)

50 % (The value of A is half of the value of B)

Write these lengths in order of size, starting with the smallest. 0.043 km 433cm 4340mm 4.3m

Ahat [919]

The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.

To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:

1 km = 1000 m
1 cm = 0.01 m or 100 cm = 1 m
1 mm = 0.001 m or 1000 mm = 1 m

Conversion of units to m:

0.043 km * (1000 m/km)= 43 m
433 cm * (0.01 m/cm) = 4.33 m
4340 mm * (0.001 m/mm)= 4.34 m
4.3 m

Lengths in order of size starting with the smallest:

4..3 m
433 cm or 4.33 m
4340 mm or 4.34 m
0.043 km or 43 m

Help i dont know what im doing this is due today

Hunter-Best [27]

Answer:

$\frac{4}{5}$ x + 5 = -3

x=-10

-2x -4 +8x -12

2(3x - 8)

Step-by-step explanation:

Multiply both sides of the equation by 5: 4x + 25 = -15

Move the constant to the right-hand side and change its sign : 4x = -15 - 25

Calculate the diffrerence: 4x = -40

Divide both sides of the equation by 4 : x= -10

Collect like terms: 6x-4-12

Factor out 2 from the expression : 2(3x - 8)

During the eclipse on January 26, 2009, the moon's shadow traveled 14,500 kilometers and covered 0.9 percent of the surface area

vfiekz [6]

The area covered by the shadow is given by:
A = (512,000,000) * (0.9 / 100)
A = 4,608,000
Then, since the area is a rectangle we have:
A = (w) * (l)
Where,
w: width
l: long
Substituting we have:
4,608,000 = (w) * (14,500)
Clearing w we have:
w = (4,608,000) / (14,500)
w = 317.7931034
Round to the nearest kilometer:
w = 318 Km
Answer:
The width of such a rectangle would be:
A: 318km
