Answer: The answer is A because the area is all the points added together so you need to times it by Y and you get the area which is 4.9

Answer 2

Answer: A and B. A is xy=A (4.9) : 2.5*y=4.9 and B is A/x=y so 4,9/2,5=1,96 which is correct

40 percent of the 35 male guests wear glasses. Write the number of male guests who wear glasses as a fraction of the 56 guests. Give your answer in its simplest form.

Answers

First off, to find the number of male guests who wear glasses, you multiply the number of guest (35) by 40% (.4).
$35(.4)=14$

Now just put the number of male guests wearing glasses (14) in fraction form over the total number of guests (56) and simplify.
$(14)/(56) = (7)/(28) = (1)/(4)$

$(1)/(4)$ of the guests are males who wear glasses.

Final answer:

Out of 35 male guests, 40% wear glasses. So, the number of male guests who wear glasses is 14. As a fraction of the total 56 guests, this can be represented as 1/4.

Explanation:

To find the number of male guests who wear glasses as a fraction of the total guests, we need to first calculate the number of male guests who wear glasses.

Out of the 35 male guests, 40% wear glasses.

40% of 35 is calculated as 0.4 * 35 = 14.

So, there are 14 male guests who wear glasses.

Now, to express this as a fraction of the total 56 guests, we write it as 14/56. This fraction can be simplified to 1/4 by dividing the numerator and denominator by 14.

108.66 degrees

Answer:

$\theta=108.66\°$

Step-by-step explanation:

Let

$\theta$ -------> the angle

we know that

$cos(\theta)=-0.32$

using a calculator

$arccos(-0.32)=cos^(-1)(-0.32)= 108.66\°$

Jenny filled 12 pitchers with equal amount of lemonade in each. The total amount of lemonade in the 12 pitchers was 41.4 liters. How many liters of lemonade would be in 7 pitchers

Answers

Answer:

24.15 liters of lemonade would be in 7 pitchers.

Step-by-step explanation:

The total amount of lemonade was 41.4 liters.

Jenny filled 12 pitchers with equal amount of lemonade in each.

So dividing total amount of lemonade by number of pitchers will yield amount of lemonade in each pitcher.

Hence,

$\text{Amount of lemonade in each pitcher}=\frac{\text{Total lemonade}}{\text{Number of pitchers}}$

$=(41.4)/(12)$

$=3.45\ lit$

Then the amount of lemonade in 7 pitchers will be,

$=3.45* 7=24.15\ lit$

24.15 liters of lemonade would be in 7 pitchers

Comparison is an effort to compare two or more objects in terms of shape or size, or number

Proportional Comparisons / Directly proportional are comparisons of two or more numbers where one number increases, the other numbers also increase at the same rate

Can be formulated

$\displaystyle \frac {x1} {y1} = \frac {x2} {y2}$

so that if:

x = 2

then

$\displaystyle y ={ \frac {y} {x} * \: 2}$

While the reversal value comparison / inversely proportional is the comparison of two or more numbers where one number increases, the other number decreases in value

or when one value decreases at the same rate that the other increases

Can be formulated

$\displaystyle \frac {x1} {y2} = \frac {x2} {y1}$
