If you think of the equation as an equation for a line.

you can see the slope of the graph is 5/9

, which means that for an increase of 1 degree Fahrenheit, the increase is 5/9

of 1 degree Celsius. Therefore, statement I is true.

This is the equivalent to saying that an increase of 1 degree Celsius is equal to an increase of 9/5

On the other hand, statement III is not true, since a temperature increase of 9/5

The final answer is D.

Answer:

1. 18

2. 5

3. 8

4. 6

5.-12

Step-by-step explanation:

im not really sure how to explain it to you but the first one that were positive numbers you can just subtract them and get the answer which i gave the forst five to you and when you are this is just an example of the adding the negative numbers 4. -15 + n = -9 you can subtract it and you'll get -15 - (-9) = -6

but if you put negative six it's gonna be the wrong answer sooo you just switch it to a positive number 6 because if you put -15 + (-6) = -21 and when its like this -15 + n = -9 the answer is smaller that the bigger number sooo the only right thing to do it put the positive 6

i hope i got you understanding it a little more if i didnt im soory i tried but the 5 answers i gave you correct

Answer:

C. 10

Step-by-step explanation:

5+5=10

10+10=20

10+20=30

Answer:

The other is 10 yards long

Step-by-step explanation:

For a given rectangle

Perimeter (P) = 30 yards

and one of rectangle is 5 yards

Now,

Perimeter of rectangle

P = 2l + 2b

30 = 2(5) + 2b

30 = 10 + 2b

30 - 10 = 2b

20 = 2b

b = 20 ÷ 2

b = 10 yards

Thus, The other is 10 yards long

Answer:

length = 5 mm

Step-by-step explanation:

area = width x length

20 mm² = 4 mm x length

divide both sides of the equation by 4 mm:

length = 5 mm

Answer:

lenght 5

Step-by-step explanation:

Answer:

Volume = 120 cubic cm

Step-by-step explanation:

We would apply the formula for determining the volume of a square bases pyramid which is expressed as

Volume = 1/3 x base area x height

From the diagram,

length of square base = 6 cm

The base area = 6^2 = 36

height = 10

Thus,

Volume = 1/3 x 3/6 x 10

Volume = 120 cubic cm

I hope this help you! :)

Answer:

The ratio of boys to girls is 4:5. So let 4x be the number of boys and 5x be the number of girls. Then 4x+5x = 9x is the total number of students. Then the fraction of boys in the class is 4x/9x = 4/9.

Answer:

2 inches would be left

Step-by-step explanation:

Answer/Step-by-step explanation:

1. B = 180 - (90 + 58) (sum of triangles)

B = 32°

Let's find a and b using trigonometric ratios:

Reference angle = 58°

Opposite = a = ?

Hypotenuse = c = 27

Adjacent = b = ?

✔️To find a, apply SOH:

Sin 58 = Opp/Hyp

Sin 58 = a/27

a = 27*Sin 58

a = 22.8972986 ≈ 22.9 (nearest tenth)

✔️To find b, apply CAH:

Cos 58 = Adj/Hyp

Cos 58 = b/27

b = 27*Cos58

b = 14.3 (nearest tenth)

2. B = 180 - (90 + 63) (sum of triangles)

B = 27°

Let's find a and b using trigonometric ratios:

Reference angle = 63°

Opposite = a = 11

Hypotenuse = c = ?

Adjacent = b = ?

✔️To find b, apply TOA:

Tan 63 = Opp/Adj

Tan 63 = 11/b

b = 11/Tan 63

b = 5.6 (nearest tenth)

✔️To find c, apply SOH:

Sin 63 = Opp/Hyp

Sin 63 = 11/c

c = 11/Sin 63

c = 12.3 (nearest tenth)

Answer:

$16,750

Step-by-step explanation:

It took a lot of plugging in and guessing

The formula used was 16750(1+.04)^1

That equaled 17420

17420-16750 is 670

Answer:

f(- 5) = 25

Step-by-step explanation:

To evaluate f(- 5) , substitute x = - 5 into f(x) , that is

f(- 5) = - (- 5)² - 10(- 5) = - 25 + 50 = 25

Step-by-step explanation:

Answer:

The y-int represents the base price of $200 for airfare from NYC

The slope represents a cost of 30 cents per mile traveled

If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x

If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x

Answer:

a^7 b^3

Step-by-step explanation:

The question can be interpreted as

[(a^9)( b ^10)] / [(a^2 )×( b ^7)]

Then we can bring the denominator up, which means the power on the denominator will become (-ve) once it comes to the numerator side. Then we have

a^(9-2) × b^(10-7)

We can simplify by performing substraction on the power

= a^7 b^3

Step-by-step explanation:

-0.01 (65)+110 = 109.35

It was the predicted value of the 65 year old's vision score.

Since the equation has an equal sign

y (=)

And not more than nor less than, answer choices C and D are eliminated.

The exact value for the 65 year old's vision score is 102. So, A isn't right.

Answer:

x = 21

Step-by-step explanation:

ALL triangles add up to 180 degrees

180 = 22 + 57 + (5x - 4)

180 = 79 + (5x - 4)

101 = 5x - 4

105 = 5x

21 = x

Answer:

A = 2x² + x - 45

Step-by-step explanation:

The area (A) of a rectangle is calculated as

A = length × breadth , thus

A = (2x - 9)(x + 5) ← expand using FOIL

   = 2x² + 10x - 9x - 45 ← collect like terms

    = 2x² + x - 45
