Answer:

A. 9 vertically and -3 horizontally

Explanation:

shifts 9 ↑ vertically upwards so positive.

shifts -3 ← horizontally towards left so negative.

note: vertically is up ↑ and bottom ↓ , horizontal is right → and left ←

Answer:

9 vertical and -3 horizontal

Step-by-step explanation:

So, lets take a coordinate from block 1. Choice: (-2, -7)

Lets take the coordinate from the same point on block 2. Choice: (-5,2)

Now lets find the difference.

The difference between x1 and x2 is the difference between -2 and -5, which is -3.  Since to go from -2 to -5 you go down -3.

This is a horizontal translation of -3

The difference between y1 and y2 is the difference between -7 and 2, which is 9. Since to go from -7 to 2 you go up 9.

This is a vertical translation of 9

So the answer is:

9 vertical, -3 horizontal

Answer:

36%

Step-by-step explanation:

If there are 100 squares of equal size

There are 36 squares that are shaded

36 out of 100 as a percentage is 36%

Answer:

36%

Step-by-step explanation:

First, count how many squares there are. There are 36 shaded squares according to my count.

Then, since we are trying to find what percent 36 is out of 100, we divide the part (P) by the total (T).

36/100= 0.36

Multiply that number by 100 and you have your percentage!

Answer:

[tex]\dfrac{59}{15}=3 \frac{14}{15}[/tex]

Step-by-step explanation:

Convert the mixed number into an improper fraction:

[tex]3 \frac35=\dfrac{3\times5+3}{5}=\dfrac{18}{5}[/tex]

Now convert fractions so that their denominators are the same:

[tex]\implies \dfrac{18}{5}+\dfrac13=\dfrac{18\times3}{5\times3}+\dfrac{1 \times5}{3 \times 5}=\dfrac{54}{15}+\dfrac{5}{15}[/tex]

As the denominators are now the same, we can simply add the numerators:

[tex]\implies \dfrac{54}{15}+\dfrac{5}{15}= \dfrac{54+5}{15}=\dfrac{59}{15}[/tex]

Now convert back into a mixed number (if required):

[tex]\implies \dfrac{59}{15}=3 \frac{14}{15}[/tex]

Answer:

3 14/15

Step-by-step explanation:

Separate the numbers between their round numbers and fractions: 3 and 3/5, 0 and 1/3.

The round number parts: 3 + 0 = 3

The fraction parts:

3/5 + 1/3

= 3*3/5*3 + 5/5*3

= 9/15 + 5/15

= (9 + 5)/15

= 14/15

Combining the two parts: 3 3/5 + 1/3

= 3 14/15

Answer:

√3

Step-by-step explanation:

From the formula used in calculating Friction, we have:

Frictional Force = coefficient of Friction × Reaction

i.e Fr = μ × R

Resolving Frictional Force and Reaction of a body moving with on an Inclined plane,

Frictional Force = mass × g × sin a

where a = to the angle given

Reaction = mass × g × cos a

Therefore,

mass × g × sin a = μ × mass × g × cos a

mass and g cancels out on both sides.

Therefore,

sin a = μ × cos a

make "μ" subject.

μ = sin a/cos a

(recall: tan a = sin a /cos a)

μ = tan a

recall a = angle given = 60°

μ = tan 60°

μ = √3

or simply recall that

μ = tan a

μ = tan 60°

μ = √3

Answer:21:)

Step-by-step explanation:

Answer: The slope is undefined.

Step-by-step explanation:

The slope of a line is (y2-y1)/(x2-x1) given two points (x1,y1) and (x2,y2).

We can plug in the coordinates given.

= (-3-2)/(-1-(-1))

= -5/0

That value is undefined beacuse you cannot divide a value by 0.

Answer:

15 feet

Step-by-step explanation:

The area of a rectangle is length × width = area. We're given the area as 285 square feet, and the width as 19 feet.

Now, we divide 285 by 19.

Thus, the answer is 15 feet.

Answer:

You're right, it is 359!

Let's break down the problem.

The equation is...

21 - 359 / 26 = 13

Therefore,

The missing number, n, is 359.

Answer:

10 meters²

Step-by-step explanation:

Method 1 ~

This method adds the triangle with the two rectangles.

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

First find the area of the largest rectangle ~

Width = 4 meters - 2 meters = 2 meters

Length = 3 meters

Area = Width × Length = 2 meters × 3 meters = 6 meters²

Then find the area of the second rectangle ~

Width = 1 meter

Length = 2 meters

Area = Width × Length = 1 meter × 2 meters = 2 meters²

Then find the area of the triangle ~

Base = 3 meters - 1 meter = 2 meters

Height = 2 meters

Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²

Finally, add the triangle and the two rectangles together ~

6 meters² + 2 meters² + 2 meters² = 10 meters²

Method 2 ~

This method subtracts the triangle from the whole rectangle.

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

First find the area of the rectangle ~

Width = 3 meters

Length = 4 meters

Area = Width × Length = 3 meters × 4 meters = 12 meters²

Then find the area of the triangle ~

Base = 3 meters - 1 meter = 2 meters

Height = 2 meters

Area = [tex]\frac{bh}{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = [tex]\frac{4}{2}[/tex] = 2 meters²

Lastly, subtract the triangle with the rectangle ~

12 meters² - 2 meters² = 10 meters²
