Step-by-step explanation: I just did it and got it right

They have the same amount of tokens after t = 7.6 hours.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Since Gavin initially has 50 token and rides the roller coaster three times per hour, he uses 3 token per hour.

So, a number of token he losses after t hours is 3 token per hour × t hours = 3t.

Thus, the number of tokens left after t hours is T = 50 - 3t

Since Gibson initially has 12 tokens and find two tokens on the ground per hour, he gains 2 tokens per hour.

So, number of token he gains after t hours is 2 token per hour × t hours = 2t.

Thus, the number of tokens he has after t hours is T' = 12 + 2t

To find the time t when they will have the same tokens, T must be equal to T', that is T = T'.

So, 50 - 3t = 12 + 2t

Now collecting like terms, we have

50 - 12 = 3t + 2t

38 = 5t

Then dividing both sides by 5, we have

t = 38/5

t = 7.6 hours

Hence, they have the same amount of tokens after t = 7.6 hours.

Step-by-step explanation:

Each triangle has a total degree of 180° so you know that one triangle has degrees of 90°&55° then you can subtract that from 180 to find out. But since they are similar they have to have the same angles and the first triangle tells you the missing angle.

Answer: 16 m

Step-by-step explanation:

Using the Pythagorean theorem you can find the height of the mast.

The formula is;

a² + b² = c²

a is one side of the triangle such as the width

b is another side such as the height

c is the hypotenuse which is the longest side.

c will therefore be 20m.

a will be 12m

12² + b² = 20²

b² = 400 - 144

b² = 256

b = √256

b = 16m

Answer:

Sarah is 13 years old

Step-by-step explanation:

Represent Sarah's age with S

Her first brother's age with F

Her second brother's age with B

So, we have:

From the first statement, we have:

[tex]S - F = 5[/tex] ---- (1)

From the second, we have:

[tex]S - B = 8[/tex] ---- (2)

The product of their ages is 40.

First, we make F the subject in (1) and B the subject in (2)

[tex]F = S - 5[/tex]

[tex]B = S - 8[/tex]

Their product is represented as follows:

[tex]F * B = 40[/tex]

Substitute values for F and B

[tex](S - 5) * (S - 8)=40[/tex]

Open bracket

[tex]S^2 - 5S -8S + 40 = 40[/tex]

[tex]S^2 - 13S + 40 = 40[/tex]

Subtract 40 from both sides

[tex]S^2 - 13S = 0[/tex]

Factorize:

[tex]S(S - 13) = 0[/tex]

Split:

[tex]S = 0[/tex] or [tex]S - 13 = 0[/tex]

But Sarah's age can't be 0 because she has two younger brothers.

So, we stick to

[tex]S - 13 = 0[/tex]

Make S the subject

[tex]S = 13[/tex]

Hence, Sarah is 13 years old

Answer/Step-by-step explanation:

✔️Slope of the first graph:

Using two points on the line, (0, 1) and (3, 2),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{3 - 0} = \frac{1}{3} [/tex]

Slope = ⅓

✔️Slope of the second graph:

Using two points on the line, (0, 0) and (1, 1),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 0}{1 - 0} = \frac{1}{1} = 1 [/tex]

Slope = 1

✔️Slope of the third graph:

Using two points on the line, (0, 1) and (2, 2),

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 1}{2 - 0} = \frac{1}{2} [/tex]

Slope = ½

The correct slopes of the graphs are as follows:

1.   m = 1 / 3

2. m = 1

3. m = 1 / 2

slope = m = y₂ - y₁ / x₂ - x₁

1.

(0, 1)(6, 3)

m = 3 - 1 / 6 - 0 = 2 / 6 = 1 / 3

2.

(0, 0)(3, 3)

m =  3 - 0 / 3 - 0 = 3 / 3 = 1

3.

(0, 1)(4, 3)

m = 3 - 1 / 4 - 0 = 2 / 4 = 1 /2

Required:

The thermometer reading

let us find 2% of 350°F

2/100*350°
