BD=16 and ÁT is the<br> perpendicular bisector of BD. Y=?

iren2701 [21]

Answer:

$y= 5$

Step-by-step explanation:

Given

$BD = 16$

$BC = 2y - 2$

$CD = y + 3$

Required

Find y

$BD = BC + CD$

So, the expression becomes

$16 = 2y - 2 + y + 3$

Collect like terms

$16 = 2y + y- 2 + 3$

$16 = 3y+1$

Collect like terms

$3y = 16 - 1$

$3y = 15$

Make y the subject

$y= 15/3$

$y= 5$

an object accelerates from rest to a velocity of 4.om / s over a distance of 20m . what was it's acceleration

AfilCa [17]

Acceleration is the change in velocity over time. There's are formula's for such problems which are called kinematics equations. Look em up. One of them doesn't have t (time) in them you would normally use that one to solve this problem. 16/2/20=a=0.4m/s^2

I did it for you but please look it up, understand and memorize it ;)

a museum employee surveys a random sample of 350 visitors to the museum. Of those visitors, 266 stopped at the gift shop. Based

Naddika [18.5K]

1748 people are expected to stop at the gift shop out of 2300.

Step-by-step explanation:

Given,

Number of random sampled people = 350

Number of people who stopped at shop = 266

Percentage = $\frac{People\ stopped}{Total\ people}*100$

Percentage = $\frac{266}{350}*100=76\%$

Therefore,

76% people would stop at the gift stop.

Number of people = 2300

Expected number = 76% of total

Expected number = $\frac{76}{100}*2300$

Expected number = 1748

1748 people are expected to stop at the gift shop out of 2300.
