Hare $50 among Terry, Leroy and Johnson in the ratio 1:3:6. How much money does Johnson get? 1 point

nlexa [21]

Answer:

His share is $30

Step-by-step explanation:

Here, we are interested in knowing the amount of money that Johnson get.

From the ratio, we can see that Johnson’s ratio is the largest at 6

so to calculate his share of the $50, we add all the ratios together = 1 + 3 + 6 = 10

Now his share would be his ratio over the total * 50

= 6/10 * 50 = $30

This diagram is a straightedge and compass construction. A is the center of one circle, and B

Serhud [2]

Answer:

Correct choices are a, b, e

Step-by-step explanation:

As per diagram, the circles are equal.

Since the distance AB is the radius of both circles:

AB = AC = BC = BD = AD = r

So the answer choices:

a. AC = BC

Correct, both equal to r

b. AC = BD

Correct, both equal to r

C. CD = AB

Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3

d. ABCD is a square

Incorrect. ACBD is rhombus

e. ABD is an equilateral triangle

Correct, all three sides are equal to r

f. CD = AB + AB

Incorrect as CD = AB√3
