Beatrice built about 1/3 of a sandcastle. Linda built 4/7 of the same castle. What fraction of the sandcastle did they build tog

wlad13 [49]

Answer

Find out the what fraction of the sandcastle did they build together .

To prove

Let us assume that the fraction of the sandcastle they build together be x .

As given

$Beatrice\ built\ about\ \frac{1}{3}\ of\ a\ sandcastle.$

$Linda\ built\ \frac{4}{7}\ of\ the\ same\ castle.$

Than the equation becomes

$x = \frac{1}{3} +\frac{4}{7}$

L.C .M of (3,7) = 21

solving

$x = \frac{7 + 3\times4}{21}$

$x = \frac{19}{21}$

Therefore the fraction of the sandcastle did they build together be

$x = \frac{19}{21}$

Hence proved

In order to raise funds to attend upcoming competitions, the debate team is selling hot chocolate at a football game. They hope

konstantin123 [22]

Answer:

125 cups

Step-by-step explanation:

We're given a total of 250 as the goal, and the product being sold is 2 per, hence, we'll use the following inequality:

$2x\geq 250$

To find the amount of hot chocolate they need to sell to satisfy the inequality, we solve for x:

$2x=250\\x=125$

The debate team has to sell atleast 125 of the product to meet their goal.

Hope this helped! Have a good day.
