Answer 1

Answer: a)46. Take 42 and divide it by 3. Then multiply 14 by 4.
b)2:1. There are 2 wings for every 1 beak on a bird.
c)15 minutes. multiply 50 times 60 and that's how many times it beats per minute. Then divide 45000 by that number and that's how many minutes it should take.
d) 28%. You have to add all the students together, and you get 200. Then you divide 56 by 200.

Answer 2

Answer: for the first one:

You take the number of plain chips and divide it by 3, then multiply by four. You do this because there is a 4 to 3 ratio of hot to plain chips.

42 / 3 = 14, 14 x 4 = 56.

Second one:

Birds (usually) have two wings for each beak. Why? I don't know, ask Darwin. There is a 2:1 (two to one) ratio of wings to beaks.

Third:

50 flaps per second, 60 seconds in a minute. 50 x 60 = 3000.

45,000 / 3000 = 15 minutes.

Fourth:

56 + 120 + 24 = 200

56 / 200 = 28% of the students ate pasta

10^2 + 7^2 = c^2
100 + 49 = c^2
149 = c^2
Square root of 149 = square root of c^2 ( cancels out the ^2)
C= square root of 149

1. 12.2
2. 8.9
3. 21.7
4. 13.9

The formula is a2 + b2 =c2.

You plug in the numbers and solve. C is always the hypotenuse of the triangle. You can use the legs as either a or b.

1.
10^2 + 7^2 =C^2
100 + 49 = C^2
149 = C^2
Then square root both sides to get 12.20.

2.
19 ^2 + b^2 = 21 ^2
361 + b^2 = 441

Subtract 361 from both sides

b ^2 = 80
Square root both sides
b=8.94

3.
16 ^2 + b ^2 = 27 ^2
256 + b ^2 = 729

Subtract 256 from both sides

b ^2 = 473
Square root both sides
b=21.74

4.
5.3 ^2+ 12.8 ^2 = c ^2
28.09 + 163.84 = c ^2
191.93=c ^2
Square root both sides to get
C=13.85

Answers

area=(1/2)bh
b=legnth of base
h=legnth of height

we are given
b=3 and 1/4
area=12 and 2/5

covert everybody to improper fraction

b=3 and 1/4=3+1/4=12/4+1/4=13/4
area=12 and 2/5=12+2/5=60/5+2/5=62/5

area=(1/2)bh
62/5=(1/2)(13/4)h
62/5=(13/8)h
times 8/13 both sides (13/8 times 8/13=104/104=1)
496/65=h

D. 15/20 and 7/10

Answers

A. 4/9 and 16/45
16 / 4 = 4
45 / 9 = 5
Disproportional

B.5/12 and 25/144
25 / 5 = 5
144 / 12 = 12
Disproportional

C. 12/18 and 18/27
18 / 12 = 3/2
27 / 18 = 3/2
Proportional

D. 15/20 and 7/10
7 / 15 = 7/15
10 / 20 = 1/2
Disproportional

Answer: (c)

Let us check each of these.

A) 4/9 and 16/45
or, 1.44 and 1.355
1.44 ≠ 1.355    ( Wrong)

B) 5/12 and 25/144
or, 1.416 and1.17
1.416 ≠ 1.17    (wrong)

C) 12/18 and 18/27

or, 1.66 and 1.66
1.66 = 1.66    (Correct)

D) 15/20 and 7/10
=0.75 and 0.70
0.75 ≠ 0.70

Thus, the answer is (C)

Explain how to find the value of a line's y-intercept using its point-slope equation.

Answers

To find the value of a line's y-intercept using its point-slope equation, you can rearrange the equation to the form y = mx + b, where m represents the slope and b represents the y-intercept. The y-intercept is the value of y when x is equal to 0.

! To find the y-intercept of a line using its point-slope equation, you can substitute the coordinates of any point on the line into the equation and solve for the y-intercept. The point-slope equation is in the form y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope. Once you substitute the values and solve for y, the resulting value will be the y-intercept.
