Answer:

62.5 : 37.5

Step-by-step explanation:

When we divide 100 into 5:3 ratio the parts we make need to add up to 100

5parts +3 parts = 8 parts

100/8 parts = 12.5 are in each part

12.5*5 : 12.5*3

62.5 : 37.5

check our answer 62.5+37.5 = 100 ✅

In a certain year, the probability that a randomly selected vehicle would be involved in a deadly tire-related accident was appr

solmaris [256]

Answer:

The probability that a vehicle would be involved in a tire-related accident is $P(TRA)=8x10^{-5}$

Step-by-step explanation:

We need to calculate the probability that a vehicule would be involved in a tire-related accident.

We know that, given a tire-related accident (TRA), the probability of it being deadly (D) is 0.05. That is:

$P(D|TRA)=0.05$

We also know that the probability of being involved in a deadly tire-related accident is 0.000004 . We can express that as the probability of having a TRA multiplied by the probability of it being deadly:

$P(D|TRA)*P(TRA)=0.000004$

Merging the two expressions we have:

$P(TRA)=0.000004/P(D|TRA)=0.000004/0.05=0.00008=8x10^{-5}$

- 26 = 8 + 5(a + 2)

yawa3891 [41]

Answer:

-44/5 = a

Step-by-step explanation:

- 26 = 8 + 5(a + 2)

Subtract 8 from each side

- 26-8 = 8-8 + 5(a + 2)

-34 = 5(a +2)

Distribute

-34 = 5a +10

Subtract 10 from each side

-34-10 = 5a +10-10

-44 = 5a

Doivide each side by 5

-44/5 = 5a/5

-44/5 = a

The entire class held hands forming a big circle if the circle was 40 feet across the center then it was how many feet around ro

Virty [35]

The circle was 126 meters around.

Step-by-step explanation:

Step 1; It is given that the big circle was 40 feet across the center. This implies the distance from any particular point on the circle to any other point is 40 feet. This means the diameter of this given circle is 40 feet. Any given circle's radius is 0.5 times the diameter of that same circle. So we divide 40 by 2 to get the circle's radius. So the radius is 40/2=20 feet. So the radius of this given circle is 20 feet.

Step 2; To find how many feet around means we need to find perimeter and not area. Area means the region inside the circle whereas perimeter is how long the circle is i.e how long the circle around is. So the distance around this circle is 2 multiplied with pi and its radius. The distance around any given circle = 2πr.

Perimeter of this circle = 2 × 3.141592 × 20 = 125.6637 feet.
