Which two numbers have a least common multiple of 60? A. 12 and 15 B. 6 and 10 C. 6 and 15 D. 6 and 12

1 answer:

5 0

The least common multiple is the littlest multiple that two or more numbers have in common (e.g 12 for 2, 3, 4 and 6).

A. 12, 24, 36, 48, 60; 15, 30, 45, 60

B. 6, 12, 18, 24, 30, 36, 42, 48, 54, 60; 10, 20, 30, 40, 50, 60

C. 6, 12, 18, 24, 30, 36, 42, 48, 54, 60; 15, 30, 45, 60

D. 6, 12, 18, 24, 30, 36, 42, 48, 54, 60; 12, 24, 36, 45, 60

The answer is A.

An ice cream factory makes 29 quarts of ice cream in 5 hours. How many quarts could be made in 48 hours ? What was that rate per

Vadim26 [7]

We can easily get the quarts per hour rate by dividing the number of quarts by the number of hours:

$\text{29 quarts in 5 hours} \implies \dfrac{29}{5} = 5.8 \text{ quarts in 1 hour}$

Now that we have the quarts per hour rate, we can easily address the question: the factory could make

$5.8\cdot 48 = 278.4$

quarts in 48 hours, with a daily rate of

$5.8\cdot 24 = 139.2$

quarts per day

raketka [301]

Answer:

(See explanation below for further details).

Step-by-step explanation:

Let be a parametric curve represented by $x = 3\cdot t - 5$ and $y = 5\cdot t + 1$ , where $t$ is the parametric variable.

The curve is represented graphically with the help of a graphing tool, whose outcome is included in the image attached below. The corresponding rectangular equation is found by eliminating t of each equation.

$t = \frac{x+5}{3}$ and $t = \frac{y-1}{5}$

$\frac{x+5}{3} = \frac{y-1}{5}$

$5\cdot (x+5) = 3\cdot (y-1)$

$5\cdot x +25 = 3\cdot y - 3$

$5\cdot x -3\cdot y = -28$

The parametric equations represents a linear function (first-order polynomial).
