a bag contains yellow marbles and blue marbles, 49 in total. the number of yellow marbles is 7 less than 3 times the number of blue marbles. how many yellow marbles are there ?

Answers

Answer 1

Answer: In short there are 35 yellow marbles and 14 blue marbles. For a long explanation, lol, keep on reading.

We know there are 49 marbles but we also know that there are only two colors, yellow and blue. So, we can assume that the yellow + blue marbles = 49. I'm going to use Y for yellow and B for blue. I'm going to rewrite the same equation with these variables. Y + B = 49. The problem continues with telling us that the yellow marbles are three times more than the blue ones with seven subtracted from that. I rephrased what they told us for better comprehension. So, we can assume that Y = 3B - 7. I gave Y that equation because of what the problem told us about Y. Continuing on, we know that Y + B = 49 and Y = 3B - 7. With this information, we can substitute Y into the Y + B = 49 equation. We now get, once we substitute Y into that equation, (3B - 7) + B = 49. We can add the B's together and get 4B - 7 = 49. Now, add the 7 and we get 4B = 56. Divide the B by 4 and we get B = 14. So, we now know what B is; we plug into the original equation to find Y. We plug in B = 14 into this equation, Y + B = 49. Once B is plugged in, Y + 14 = 49. Subtract 14 from 49 and we get Y = 35. Hope this helped. Good luck!

Find the lateral area of the right prism with height 0.3 dm, if the base of the prism is: Parallelogram with sides of 6 cm and 20 mm

Answers

The lateral area of the parallelogram prism is 0.048 m²

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

0.3 dm = 0.3 m, 6 cm = 0.06 m, 20 mm = 0.02 m, hence:

The lateral area of the right prism is given by:

Lateral area = 2(0.06 * 0.3) + 2(0.02 * 0.3) = 0.048 m²

The measure of central angle XYZ is 1.25 radians.

What is the area of the shaded sector?

Answers

Note that a sector is the area bounded by two radii and the included arc. When trying to calculate for the area of the sector, you’ll use the formula A=n/360 (pi)(radius)^2. Remember that the n in the formula refers to the measure of the central angle in degrees. Since the given data in the problem is in radians term, you can convert it by multiplying 1.25 to 180/pi. Then you can now input the converted value to the formula of finding the area of the sector.
