Tristan's forecast for income next year is $3,876.

The forecast income can be determined using the mathematical operation of multiplication.

First, the total number of hours worked next year is determined as 204.  This is a product of 17 weeks and a 12-hour week.

Lastly, the above product multiplies the hourly pay rate at $9.50 by two semesters, to determine the expected income for next year.

The average hours of work by Tristan per week = 12 hours

Hourly pay rate = $9.50

The total number of weeks to work = 17 weeks

The total number of hours to be worked = 204 hours (17 x 12)

Expected earnings for each semester = $1,938 ($9.50 x 204)

Expected earnings for two semester = $3,876 ($1,938 x 2)

Thus, Tristan should expect to earn $3,876 for next year.

The scale rectangular of the pool must be 3 x 8 inches.

According to the question,

Given that,

a rectangular pool yard is 150 ft. × 400 ft,

create a scale drawing with a scale factor of 1 to 600, the following calculation must be followed :

[tex]\frac{150}{600} = \frac{1}{4} = 0.25[/tex]

[tex]\frac{400}{600} = \frac{2}{3} = 0.6667[/tex]

1 foot = 12 inches

12 x 0.25 = 3

12 x 0.666 = 8

Then, the scale drawing of the pool must be 3 x 8 inches.

“If you are going to build a model, you have to use a scale. You shrink down the real dimensions so that you can actually build a model that everyone will be able to see, think about it, Everest is 29,035 feet high, you can’t build that using the real dimensions,

First, let’s think about our unit scale.

1 inch = 3 feet

If we have a building 24 feet long, that is the actual dimensions. We need to represent the dimensions using our unit scale.

We can say that 8 inches = 24 feet. This is our answer.

First, let’s make a note of the unit scale.

1 inch = 8 feet

We have been given the scale dimension and not the actual dimension. We are going to need to solve for the actual dimension. Let’s write a proportion to do this.

scale dimension actual dimension=1 in8 ft=5 inches

We can see that one times five is equal to five. We can do this to the actual dimension as well. Eight times five is equal to forty.

The actual length of the building is 40 feet.

In this question, we have been given a statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.'

We need to check whether given statement is true or false.

The bank raised its interest rate on savings accounts from 2% to 2.8%

We find the percent increase.

Here the absolute increase is: |2.8 - 2| = 0.8

The relative increase is: absolute increase / original value

= 0.8 / 2

= 0.4

The percent increase is: relative increase × 100

= 0.4 × 100

= 40%

Therefore, given statement 'My bank raised its interest rate on savings accounts from 2% to 2.8%, which was a 40% increase.' is True.

Answer: Rate of tree's height per year = 0.275 m per year.

Rate of tree's trunk per year = 0.025 m per year.

Step-by-step explanation:

Given data,

Exactly 120 years​ ago, students planted a tree in front of their school

Since​ then, the tree has grown 33 meters taller

The distance around the trunk has increased by 3 meters.

Define Unit rate :

A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.

So, we can write,

There are 2 various unit rates in this:

The increase of the tree's height per year

The increase of the tree's trunk per year

Let us assume,

The increase of the tree's height per year = x

The increase of the tree's trunk per year = y

we can solve it :

Rate of tree's height per year x = 33m / 120 years

                                                x = 0.275 m per year.

Rate of tree's trunk per year y = 3m / 120 years

                                              y = 0.025 m per year.

Therefore,

Rate of tree's height per year = 0.275 m per year.

Rate of tree's trunk per year = 0.025 m per year.

Step-by-step explanation:

the slope of a line is always the factor of x, and it is defined as ratio (y coordinate change / x coordinate change) when going from one point to another on the line.

in that sense it is y/x.

the perpendicular slope turns that ratio upside-down and flips the overall sign.

so, in our case, the original slope is 3 = 3/1.

the perpendicular slope is then -1/3.

so, now, we have the slope and a point, and we can start with the point-slope form of the line equation :

y - y1 = a(x - x1)

"a" being the slope, (x1, y1) being the point.

y - 1 = -1/3 × (x - 9) = -x/3 + 3

y = -x/3 + 4

and that is the usual slope-intercept form

y = ax + b

"a" is again the slope, "b" is the y-intercept (the y value when x = 0).

The lenght of the side b is 5 units

According to the given information the triangle is an right angled triangle with sides a,b, c where a and b are the two legs of the triangle and c is the hypotenuse the measurments of the side a and c are given 12 and 13 respectively . For finding the value of  b we need to use pythagoras theorem that is (Hypotenuse)² = (base)² + (height)²

Here we are going to use the same theorem for finding the value of the side b

According to the question:

hypotenuse = c = 13 units

height = a = 12 units

base = b = ?

As per  the theorem : hypotenuse ² = base ² + height²

∴ (13)² = b² + (12)²

=> 169 = b² + 144

=> b² = 169 - 144

=> b² = 25

=>b = √√25 = ±5

b = 5 [∵ lenght cannot be negative ]

If we want the two ratios to be equivalent, then we need to use x = 15 and y = 33.

Let's say that we have a simple ratio between two amounts, it is A:B

If we multiply both of these amounts by the same scalar, k, we will get:

k*A and k*B

And the ratio between the new amounts k*A: k*B is equivalent to the first ratio, A:B

So we will use this to solve the problem, here we have two ratios:

5:2:11 = x:6:y

Note that in the first ratio the first value is 2, and in the second case it is 6 so let's find the value of k such that:

2*k = 6

k = 6/2 = 3

Then if we multiply the correspondent values in the first ratio by 3, we will get:

x = 5*3 = 15

y = 11*3 = 33

Then we can see that the ratios:

5:2:11 and 15:6:33 are equivalent.
