Answer:
Mr. Jenkins has 12 cups.
Step-by-step explanation:
Consider the provided information.
Mr.Jenkins has 48 paintbrushes and 60 tubes of paint to put into cups.
It is given that The greatest common factor for the number of paint brushes and the number of tubes of paint is equal to the number of cups Mr.Jenkins has.
First find the greatest common factor of 48 and 60.
48 = 2×2×2×2×3
60 = 2×2×3×5
Hence, the greatest common factor is 2×2×3=12
Therefore, Mr. Jenkins has 12 cups.
The attached diagram is a useful tool for working mixture problems. It shows the desired mix is
.. 1 kg of 30% gold
.. 3 kg of 10% gold
Step-by-step explanation:
u should:
7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8
and another one is:
2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»
» 2u + 21 = u + 36 » 2u - u = 36 - 21 » u = 15
Answer:
Step-by-step explanation:
Answer:
5√13
Step-by-step explanation:
We know that PQWV is a square because its given. A square has all congruent sides. Therfore, VW is 10. The. length of VU is fifteen because the length of PU is 25 since PRSU is a square. We know that m<PVW is 90 degrees because PQWV is a square. Therefore, we can say the m<UVW is 90 degrees because of a straight line. Using the pythagorean therom (a^2 +b^2=c^2 (where a and b are the legs and c is the hypotenuse)) we can say that √(10^2+15^2). This equals to √325. This can be simplified to 5√13.
