DOES ANYONE KNOW THE ANSWER?????????

givi [52]

There's only information to answer question C.

We can only know that 32 marbles were chosen. (yellow and black)

Why?

To answer the first two questions (a and b), we need to know the total number of marbles, so, we can only answer the last question (c).

We know that 7/10 of the 20 yellow marbles were chosen.

So, calculating we have:

$\frac{7}{10}*20=14(yellow)$

Also, we know that 18 black marbles were chosen, so, the total of marbles chosen is equal to 32 (yellow marbles and black marbles)

$TotalMarbles=14(yellow)+18(black)=32marbles$

Have a nice day!

The larger of two numbers is 10 less than twice the smaller number. If the sum of the two

natka813 [3]

Answer:

Let the larger number = y and the smaller number = x.

The largest number is 10 less than twice the smaller number. Remember that less than means subtract the 10 from the other amount while twice means multiply by two. Therefore,

y = 2x - 10

The sum of the two numbers is 38. Remember sum means add the two numbers to get their result. Therefore,

x + y = 38

Since y = 2x - 10, we rewrite the lower equation as:

x + (2x - 10) = 38

Solving:

3x - 10 = 38

3x = 48

x = 16

The lesser number is 16 and the greater number is 2(16) - 10 or 22.

Question:

alexandr1967 [171]

Answer:

Part 1) The draw in the attached figure

Part 2) $m\angle ABD=50^o$

Step-by-step explanation:

Part 1) Draw the described circle

The draw in the attached figure

Part 2) What is the measure of angle ABD

step 1

Find the measure of arc AD

Remember that

$arc\ AD+arc\ DC+arc\ AC=360^o$ ----> by complete circle

substitute the given values

$arc\ AD+124^o+68^o=360^o$

$arc\ AD=360^o-192^o=168^o$

step 2

Find the measure of angle ABD

we know that

The measurement of the external angle is the half-difference of the arches that comprise

In this problem

The measure of angle ABD is an external angle

$m\angle ABD=\frac{1}{2} [arc\ AD-arc\ AC]$

substitute the given values

$m\angle ABD=\frac{1}{2} [168^o-68^o]=50^o$
