Triangle ABC has vertices A(–3, 1), B(–2, 3) and C(–1, 1). Find its image after a rotation of 90° counterclockwise about (0, –1)

Answer:

As the time increases, the distance from the floor decreases by 40 cm per second. You find 40 by taking (6,1140) and (9,1020). The slope formula is y2 - y1 over x2- x1. Plug in the variables and you get (1020-1140)/(9-6)= -120/3= -40.

Answer:

Step-by-step explanation:

To find the median, we need to arrange the data in ascending order:

70, 71, 72, 74

Since the data set has an even number of values, the median is the average of the two middle values. In this case, the two middle values are 71 and 72. Therefore, the median is:

(71 + 72) / 2 = 143 / 2 = 71.5

So, the median for the given set of data is 71.5.

Answer:

40/ or /80

Step-by-step explanation:

Because 400 is a lot and if it's 100% is 400 right so we do 80% what would that be? we don't know right.

What about 100 pages that would be (im pretty sure) 40% or 50%.

Answer:

the answer is D. 7 1/30

Step-by-step explanation:

first make them into improper fractions:

21/5 and 17/6

second find a common denominater (im using 30) and multiply so they have 30 as the denominater:

126/30 and 85/30

third add the improper fractions:

126/30 + 85/30 = 211/30 and as a mixed number it would be 7 1/30

Answer:

D. 7 1/30

Step-by-step explanation:

4 1/5 + 2 5/6=

The first thing we notice here are the fractions, whenever working with fractions, the first thing to do to make your life easier is to find the common denominator for the fractions. What's a common denominator?? a common denominator is when two fractions can have the same number on the bottom. We know that 5 times 6 gives you 30, so 30 can be our common denominator.

4 1/30 + 2 5/30 =

ok so, we changed our denominator, but now what? since we changed the denominator, this also affects the numerator (the numbers on the top). to fix this, we have to do the same to the numerator as we did to the denominator. to change 5 into 30, we multiplied it by 6, this means we also have to multiply 1 by six, 6/30. Don't forget the other fraction too! Since we multiplied 6 by 5 to get 30, we also have to multiply 5 by 5, 25/30.

4 6/30 + 2 25/30 =  

now that the fractions have the same denominator, we can just go ahead and add the digits and numerators!

we know that 4 + 2 = 6, so we can remove them and put 6 at the end of the equation

6/30 + 25/30 =  6

but we aren't done yet, now we add 6 + 25 which gives us 31, out of 30

wait! 31/30? that doesn't sound right. 30 out of 30 automatically gives us a 1, so we can add that to the 6 we got earlier, 6 + 1 = 7. Since we are left with 1/30 we will add this to the final answer: 4 6/30 + 2 25/30 =  7 1/30

Answer:

Jiri's age = 27

Step-by-step explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer:

Jiri is 27 years old.

Step-by-step explanation:

Step 1: Declare variables

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is \(\displaystyle{8+x}\) years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of \(\displaystyle{x+8+x=62}\) (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

\(\displaystyle{2x+8=62}\)

Step 4: Subtract both sides by 8

\(\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}\)

Step 5: Divide both sides by 2

\(\displaystyle{\dfrac{2x}{2}=\dfrac{54}{2}}\\\\\displaystyle{x=27}\)

Since Jiri’s age is defined as \(x\) years old. Therefore, Jiri’s age is 27 years old.

Step-by-step explanation:

The area of the circular shaded region is given as follows:

A = 50.24 square yards.

The area of a circle of radius r is given by the multiplication of π and the radius squared, as follows:

A = πr²

The radius of a circle represents the distance between the center of the circle and a point on the circumference of the circle, while the diameter of the circle is the distance between two points on the circumference of the circle, on a segment that passes through the center. Hence, the diameter’s length is twice the radius length.

The circumference of a circle of radius r is given as follows:

C = 2πr.

Hence the radius of the inner circle is given as follows:

6.28r = 18.84

r = 18.84/6.28

r = 3 yd.

The radius of the outer circle is of 3 + 2 = 5 yd, hence the area of the shaded region is given as follows:

A = 3.14 x (5² - 3²)

A = 50.24 square yards.
