The total number of marbles times the probability of red marbles = number of red marbles

total * 7/10 = 42

Multiply each side by 10/7

total * 7/10 * 10/7 = 42*10/7

total

Pavel [41]

Answer:

6

Step-by-step explanation:

Radius of the given circle is 6 units.

Given equation of circle is:

${(x + 5)}^{2} + {(y - 7)}^{2} = 36 \\ \: equating \: it \: with \\ {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\ {r}^{2} = 36 \\ \huge \red{ \boxed{r = 6 \: units}}$

Ollie Drank 3/4 of a 16 oz bottle of juice. How many oz of juice is left in the bottle?

Alenkinab [10]

3/4th of the bottle of juice would be splitting up the 16 oz bottle into 4th, so 16 divided by 4 equals 4. Then because he only drank 3/4th of the bottle multiply the 4 by 3 equaling 12. Then subtract 12 from 16 and you get a total of 4 oz left!!!

In triangle ABC, a = 4, b = 7, and c = 10. Find A.<br> 18°<br> 34°<br> 56°<br> 162°

marusya05 [52]

Answer:

18°

Step-by-step explanation:

The law of cosines tells you ...

a² = b² + c² -2bc·cos(A)

Solve for cos(A) and fill in the numbers. Note that the value of cos(A) is very close to 1, so the angle will be fairly small. This by itself can steer you to the correct answer.

cos(A) = (b² +c² -a²)/(2bc) = (49 +100 -16)/(2·7·10) = 133/140

A = arccos(133/140) ≈ 18.2° ≈ 18°
