Answer:

BG = 3

GE = 6

Step-by-step explanation:

The ratio of lengths on BE is 2:1 and all centroid crossing median lines.

9 if broken in a 2:1 ratio is 6:3

BG is the shorter one (from centroid to midpoint on the line) so its 3

GE is the longer one (centroid to vertex) so its 6

Jamal works as an electrician’s apprentice. He rewired 4 electrical outlets in 1 1/2 hours. If he works at the same pace for 7.5

RSB [31]

This can be solve by first solving the proportionality constant

Number electic outlets rewired is directly proportional to time spent

4 = (1 ½)a

Let be the proportionality constant

A = 8/3

O = (8/3)(7.5)

o = 20 outlets will jamal rewired if he works for 7.5 hrs

from 2002 to 2012, the number of a particular make of cars sold at a dealership yearly declined to 500. The number is expected t

Alinara [238K]

To determine the number of cars that will be sold by the year 2020, we will use the equation,

N = (N1)(1 - r)^(t)

where N1 is the starting number of cars, r is the rate of the decrease, and t is the number of years from 2012. Substituting the konwn values,

N = (500)(1 - 0.028)^(8)
N = 398.38

The closest integer to the calculated value is 398. Thus, the answer is 398 cars.

Solve each equation. Check your solution.<br><br><br> 3x 32 = 7x + 28

skad [1K]

Answer:

x= 28 /89

Step-by-step explanation:

3x(32)=7x+28

Step 1: Simplify both sides of the equation.

96x=7x+28

Step 2: Subtract 7 from both sides.

96x 7x+28

−7 −7

89x=28

Step 3: Divide both sides by 89.

89x /89 = 28 /89

Answer:

Step-by-step explanation:

Because the lines that the transversals are cutting through are parallel:

$\dfrac{24}{32}=\dfrac{k}{64} \\\\\\k=64 \cdot \dfrac{24}{32}=48$

The speed of a car after accelerating for 8 seconds is inversely proportional to its weight. The car weighs 1600 kg and accelera

STatiana [176]

Answer:

With 800 extra kg load: speed = 66.667 km/h

With 2400 extra kg load: speed = 40 km/h

Step-by-step explanation:

Let's call the weight of the car W = 1600 kg, and its speed after accelerating for 8 seconds with this weight S = 100 km/h

If we load the car with 800 extra kg, the total weight will be:

W2 = W + 800 = 2400 kg

The relation between the weights is:

W2 / W = 2400 / 1600 = 1.5

If the weight increased 1.5 times, the relation between the speeds will be 1/1.5 (as they are inversely proportional), so:

S2 / S = 1 / 1.5

S2 = S / 1.5 = 66.667 km/h

If we load the car with 2400 extra kg, the total weight will be:

W3 = W + 2400 = 4000 kg

The relation between the weights is:

W3 / W = 4000 / 1600 = 2.5

If the weight increased 2.5 times, the relation between the speeds will be 1/2.5, so:

S3 / S = 1 / 2.5

S3 = S / 2.5 = 40 km/h
