Answer:

Q1.

AC is the greatest side, therefore is hypotenuse. AB and BC are legs.

B is 90 deg as the two legs cross at this point.

<u>Ratios:</u>

  • sin = opposite / hypotenuse
  • cos = adjacent / hypotenuse
  • tan = opposite / adjacent

BC is opposite to A and adjacent to C

AB is adjacent to A and opposite to C

  • sin A = cos C = 8/10 = 4/5
  • cos A = sin C = 6/10 = 3/5
  • tan A = cot C = 8/6 = 4/3
  • tan C = cot A = 6/8 = 3/4

The area of a rectangle is 42 square inches. the length is 7 inches.what is the perimeter of the rectangle?
andrew11 [14]

In order to find the perimeter, we need to have the length and the width. We are told that the area of the rectangle is 42. We will use that in the area formula, length times width, to solve for w. 42 = 7w so w = 6. The length is 7 and the width is 6. The perimeter formula for a rectangle is P = 2L + 2W. We have both the length and the width now, so we fill in accordingly. P = 2(7) + 2(6). And P=14+12. The perimeter then is 26 inches.

The family size bottle of sunscreen holds 12121212 fluid ounces (fl oz)(\text{fl oz})(fl oz)(, start text, f, l, space, o, z, en
Musya8 [376]

Answer:

The regular bottle holds 9 fl oz less

Step-by-step explanation:

Given

Family Size =  12 fl oz

Required

Determine the size held less by the regular bottle

From the question, we have that the regular bottle holds 75% less;

Regular\ Size = 75\% * Family\ Size

Substitute 12 fl oz for Family Size

Regular\ Size =75\% * 12\ fl\ oz

Convert percentage to fraction

Regular\ Size = \frac{75}{100} * 12\ fl \oz

Regular\ Size = \frac{75 * 12\ fl\ oz}{100}

Regular\ Size = \frac{900\ fl\ oz}{100}

Regular\ Size = 9\ fl\ oz

<em>Hence, the regular bottle holds 9 fl oz less</em>
