Hi There!
Answer:
A.) variables that were manipulated during the experiment
Least important to most important steps to include in a summary:
- variables that were manipulated during the experiment.
- list of all materials and equipment used in the experiment.
- number of scientists involved in the experiment.
- laboratory room number in which the experiment took place.
Hope This Helps :)
Answer:
The contribution margin it's determined by the total amount of Gross Profit divided by the total value of sales.
Profit = $405,000
Sales = 11,250×106 =$1,192,500
Therefore contribution margin ratio = ($405,000/$1,192,500) = 0.34
The Break Even point is given thus;
Fixed cost = 25 × 11250 =$281,250
Break-even point = Fixed costs ÷ contribution ratio
= $281,250/0.34 = $827,205.88
Answer:
B) BC'= 8, m A'= 28°
Step-by-step explanation:
When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.
To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':
- BC' = BC×1/2
- BC' = 16×1/2
- BC' = 8
The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.
Answer:
A
Step-by-step explanation:
Hi
The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse
so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.
b ) sin 45 = 1 / sqrt2 = sqrt2 / 2
c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2
