jarptica [38.1K]

Answer:

m=7

Step-by-step explanation:

1 blue jar = 21 marbles

1 blue jar = 3 red jars

Therefor

21 marbles= 3 red jars

(Now let m=1 red jar)

21= 3m

(Then sine we have 3m dived both sides by 3 to isolate the m)

21/3= 3m/3

7=m

Help please and thank you!!!
max2010maxim [7]

Hello!

So, let's go over some information we know. We know that all the interior angles of a triangle add up to 180 degrees. We know that a line measures 180 degrees. We, therefore, know that angles which make up a line are supplementary, and must add up to 180 degrees.

So, first, we can find angle ABC. We can find this because angle ABC and ABT add up to 180 degrees, and we know the measure of ABT to be 125 degrees. Therefore:

ABC + 125 = 180

ABC = 55 degrees

Now, we can find angle ACB. We can find this as we have angle ABC and CAB, and angle ACB + ABC + CAB = 180 degrees (as they are the three interior angles of triangle ABC). ABC measures 55 degrees, and CAB 60 degrees. Therefore:

55 + 60 + ACB = 180

115 + ACB = 180

ACB = 65 degrees

Finally, we can find angle ACR based off of ACB, as ACB and ACR make up one line, and, therefore, add up to 180 degrees. ACB measures 65 degrees.

ACR + 65 = 180

ACR = 115 degrees

Therefore, your answer is choice 2, or 115 degrees.

Hope this helps!

Archy [21]

Answer:

12th Customer

Step-by-step explanation:

We have to find the lcm (lowest common multiple) of the number.

We do that by taking their multiples. Watch down below

3 x 1 = 3                4 x 1 = 4

3 x 2 = 6               4 x 2 = 8

3 x 3 = 9               4 x 3 = 12

3 x 4 = 12

See how they both have a 12 as their first lcm.

So the 12th customer gets both items.

Glad to help!

Two sides of a triangle have length 10 and 17. What is the range of the length of the 3rd side
andriy [413]

Answer:

13.7477270849 to 19.7230829233.

Step-by-step explanation:

1. Using the pythagorean theorem, a²+b²=c², we try different combinations of given lengths 10 and 17.

2. If 10 and 17 are legs and 10²+17²=√389 = 19.7230829233, then c=19.7230829233.

3. If 10 is a leg and 17 is a hypotenuse,

10²+b²=17²

100+b²=289

b²=189

b=13.7477270849

4. The case of 17 is a leg and 10 is a hypotenuse is not possible because the hypotenuse is the longest side.

5. The range of the length of the 3rd side is 13.7477270849 to 19.7230829233.
