Answer:

15/20 : 2/20 : 3/20 or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher

Step-by-step explanation:

We know that there are 3 ingredients.

3/4 apple juice

1/10 orange juice

We want to know how much cranberry juice to apple juice to orange juice.

First, let's start with getting common denominators.

The LCD (least common denominator) between these two fractions is 40. (4 * 10)

So:

3/4 * 10/10  = 30/40

1/10 * 4/4 = 4/40

Now we know them with equal denominators. Now let's subtract them from the whole (40/40) to find out how much cranberry juice.

40/40 - 30/40 - 4/40 = 6/40

Cranberry juice = 6/40 of the whole.

Now we can find the ratio in its simplest form.

30/40 : 4/40 : 6/40

Can we simplify these fractions? yes.

The can all be simplified by 2

15/20 : 2/20 : 3/20

Since 2 can't be simplified by anything but 2 or 1, and 15 and 3 cannot be simplified by 2, this is your answer.

or you could put 3/4 : 1/10 : 3/20 but that's up to your teacher.

Answer:

6.4 = b     and     7.8 = a

Step-by-step explanation:

Using the formula:

a^2 + b^2 = c^2

we can find the length of b

for the first triangle

now we just plug in the lengths.

5^2 + 4^2 = b^2

simplify into :

25 + 16 = b^2

add

41 = b^2

now in order to get rid of the ^2, we just find the square root of 41.

√41 ≈ 6.4

6.4 = b

Now we just need to solve for A

since we know

a^2 + b^2 = c^2 that must mean

c^2 - b^2 = a^2

so this is the formula we will be using.

now we just plug in the lengths of the second triangle into this equation.

10.5^2 - 7^2 = a^2

simplifies into

110.25 - 49 = a^2

subtract

61.25 = a^2

now we just find the square root of 61.25.

√61.25 = 7.8

7.8 = a

you can check this by putting it back in the formula

a^2 + b^2 = c^2

I will do this quickly (only for the second triangle)

we know

a = 7.8

b = 7

c = 10.5

7.8^2 + 7^2 = 10.5^2

simplifys into

60.84 + 49 = 110.25

60.84 + 49 ≈ 110

110.25 ≈ 110

110 = 110

which proves that this is correct.

Answer:

x ≈ 5.3

Step-by-step explanation:

a²+b²=c²

c is always the hypotenuse in a right angle triangle.

6² + x² = 8²

36 + x² = 64

64 - 36 = 28

x² = 28

x = √28

Use calculator from here.

√28 = 5.29150262213

5.29150262213 ≈ 5.3

Because the number after 2, which is 9, is greater than 5, the nearest tenth is 5.3, not 5.2.

Step-by-step explanation:

area of the trapezoid = area of the 2 triangles +

area of the rectangle

i) area of triangle on left:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

ii) area of triangle on right:

a = ½ bh

a = ½ × 2 × 9

a = 9 in²

iii) area of rectangle = length × width

a = l × w

a = 12 × 9

a = 108 in²

iv) area of trapezoid = 9 + 9 + 108

= 126 in²

hope this helps you!

Answer:

84.9

Step-by-step explanation:

The distance between first and third base makes the hypotonus of a triangle where the lengths of the legs are each 60 feet. To find the hypotonus, add (60)^2 + (60)^2 to get 3600 +3600 = 7200. Then square root 7200 to get the distance between first and third as 84.9

Answer: Choice C and Choice D

========================================================

Explanation:

Answer:

[] Noah shares 7 grapes with 3 friends. He eats 1 and gives each friend the same number of grapes.

[] Andre studies 7 hours this week for end-of-year exams. He spends 1 hour on English and an equal number of hours each on math, science, and history.

Reasoning:

[✗] The first story, with Diego, does not work because the whole is $1 in the problem and $7 in the diagram.

[✗] The second story, with Elena, does not work because the 7 is ignored entirely and the x becomes a known value, 57.

[✓] The third story, with Noah, does work because he splits seven grapes equally among three friends (the x's) and eats one.

[✓] The fourth story, with Andre, does work because 7 hours were spent studying. One on English and the rest (three subjects) split evenly (x).

[✗] The fifth story, with Lin, does not work because the total is $3 when it should be 7.

Answer:

Any points across y=5. ex: (-2,5) (0,5) (1,5), (3,5) (4,5)

Step-By-Step Solution

(3y=15)/3 divide all by 3

and get y=5

any 5 points that gave y=5 will work

Answer: PART A.

y= remaining height of candle

x= rate the candle burns down in inches per hour

8= original height of candle

the function would be y=8- 0.5x because the candle starts at a height of 8 feet and loses half an inch per hour.

You can use this function to create ordered pairs by putting in number at x which indicates the time:

x=1

y=8- (.5×1)= 7.5

(1, 7.5)

you can then do this for other numbers and get:

(2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)

PART B.

This equation is a function because all of the x-values had different y-values as seen in the coordinates (1, 7.5) (2, 7.0) (3, 6.5) (4, 6.0) (5, 5.5) (6, 5.0)  

PART C.

If the rate was 0.4 inches an hour, it would still be a function because the rate is the only thing that changed making the new function y= 8- 0.4x.This equation would make coordinates of (0,8) (1, 7.6) (2, 7.2) (3, 6.8) and so on with each x value creating a different y value.
