For the first one to find the total area you have to first find the area of the triangle 1/2(10x12.5)=62.5 and then the square (13.4x12.5)=167.5 which is 10468.75 totaled

Problem 2

<h3>Answer:  230 square meters</h3>

------------

Work Shown:

Area of triangle = 0.5*base*height

Area of triangle = 0.5*10*12.5

Area of triangle = 62.5

Area of rectangle = base*height

Area of rectangle = 13.4*12.5

Area of rectangle = 167.5

Total area = (area of triangle)+(area of rectangle)

Total area = 62.5+167.5

Total area = 230 square mm

As an alternative, you can use the trapezoid formula to get the same answer.

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

Problem 3

<h3>Answer: 200 square mm</h3>

------------

Work Shown:

A = area of smaller square

A = side*side

A = 5*5

A = 25 square mm

B = area of larger square

B = side*side

B = 15*15

B = 225 square mm

C = area of shaded region

C = B - A

C = 225 - 25

C = 200

How do you describe a sequence of rigid motions?
Burka [1]

See the explanation

<h2>Explanation:</h2>

Rigid motions are transformations we perform on a figure in order to move it without changing the size or shape of it. They are also called <em>congruence transformations </em>because we can map one figure onto other figure so they will maintain every condition in order to be congruent.

Rigid motions are the following:

  • Reflections: Here we reflect the figure across a line
  • Translations: Here we move the figure either horizontally or vertically
  • Rotations: Here we turn the figure either counterclockwise or clockwise.

So sequence of rigid motions could be any combination we get from the mentioned transformations. For instance:

Perform the transformation of triangle ΔABC following this sequence:

1. Translate the figure 2 units right and 4 units down

2. Reflect the figure across the x-axis

3. Rotate the figure 90 degrees in clockwise direction

When graphing an ordered pair, what is the first number and what does it tell you to do?
TEA [102]
The answer is D. In an ordered pair, the x-value, which tells you to move left or right, comes first, followed by the y-value, which tells you to move up or down.

Rachel has $80 in a savings account.The interest rate is 10%per year and is not compounded. How much interest will she earn in 1
erma4kov [3.2K]

Answer:

I = $ 8.00

Equation:

I = Prt

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 10%/100 = 0.1 per year,

then, solving our equation

I = 80 × 0.1 × 1 = 8

I = $ 8.00

The simple interest accumulated

on a principal of $ 80.00

at a rate of 10% per year

for 1 years is $ 8.00.

The average winter snowfall in City A is 105 cm. City B usually gets 2.8 m of snow each winter. Compare the yearly snowfall in t
Inessa [10]
We see that city A gets 105 cm of snow while city B gets 2.8 m. The first thing we do is make both measurements equal to each other. This can be done by either converting city A's 105 centimeters to meters or city B's meters to centimeters. But the question specifically calls for both, so we get both measurements.

City A: 105 centimeters OR 1.05 meters
City B: 280 centimeters OR 2.8 meters

Now that we know the measurements, let's look at the first problem. (A) asks for the difference in one year in meters. The difference of course means subtraction. Now it's here where I personally am confused on what it asking for in terms of which city is it asking for us to subtract from, but using an educated guess, I'll say we're subtracting from city B because if we were to subtract from city A, we'd have a negative, and you can't have a negative amount of snow, only 0 snow.

So once again, for question (A), we subtract 1.05 from 2.8 (2.80 - 1.05) and we get 1.75 meters of snow.

Question (B) asks for the difference during two years in centimeters, so we multiply both measurements by 2 and use the centimeter measurements. (105 x 2 = 210) (280 x 2 = 560) Subtract 560 from 210 (560 - 210) and we get 350 centimeters.

So your answers are: (A) 1.75 meters (B) 350 centimeters

I hope this helps!
