The label on a juice carton says there are 50 calories in a 4-ounce serving of juice.

Scrat [10]

The answer is D
Because, if there is 50 calories in 4 ounce serving of juice, then you do how many times 4 equals 12. 3 times 4 equals 12. so you will use 3 to multiply by 50 and you get 150 calories in 12 ounces.

a child lies on the ground and looks up at the top of a 14-ft tree nearby. the child is 7 ft away from the tree. what is the ang

iragen [17]

Answer:

63°

Step-by-step explanation:

From the diagram, the angle of elevation from the child to the top of the tree can be calculated using the tangent ratio.

Recall SOH-CAH-TOA from your Trigonometry class.

The tangent is opposite over adjacent.

$\tan(A) = \frac{14}{7}$

$A = \tan^{ - 1} ( 2)$

$A = 63.43 \degree$

The angle of elevation is 63° to the nearest degree.

a kitten weighs four whole pounds and 2/3 of a fifth pound which mixed number represents the kittens weight?

Aneli [31]

Given that a kitten weighs four whole pounds and 2/3 of a fifth pound.

In this type of problem it is always best to break the given statement into smaller pieces then writing expression for each piece will be more easy.

"fifth" means 1/5.

so 2/3 of a fifth means product of 2/3 and 1/5 which is

$\frac{2}{3}*\frac{1}{5}=\frac{2*1}{3*5}=\frac{2}{15}$

Now total weight is given by

4 whole pounds and 2/3 of a fifth

$= 4 + \frac{2}{15}$

$= 4*\frac{15}{15} + \frac{2}{15}$

$= \frac{60}{15} + \frac{2}{15}$

$= \frac{60+2}{15}$

$= \frac{62}{15}$

Hence required fraction for the answer is $\frac{62}{15}$ .
