Answer:225 tiles

Step-by-step explanation:

area of floor=number of  tile * area of each tile

side*side= x *(side*side)

300*300=x * (20*20)

300/20*300/20=x

15*15=x

225=x

Answer:

122ft

Step-by-step explanation:

(Note that this is just a logical guess, I do not remember learning how to do this)

We are given the length of the pole and the length of the guy wire after the pole. This gives us a right angle triangle where we know two of the sides. We can the other two sides into the Pythagorean theorem to solve for the diagonal side

recall:

[tex]{a}^{2} + {b}^{2} = {c}^{2} [/tex]

plugged in 12ft and 2ft we get:

[tex] {(12)}^{2} + {(2)}^{2} = 148[/tex]

to solve for the diagonal side we take the square root of 148

[tex] \sqrt{148} = 12.17[/tex]

so now we know that 12.17 ft of wire is equivalent to 2 feet on the ground.

[tex] \frac{12.17ft \: wire}{2 \: ft \: ground} [/tex]

We have a total of 20 feet, so we multiply this proportion by 20:

[tex] \frac{12.17}{2} \times 20 = 121.7[/tex]

we are asked to give to the nearest foot so we round up to 122ft

Rotation involves moving a point around a center

The coordinates of M" are (-2,-3)

The pre-image M is given as:

M =(-3,-2)

The rule of 270 degrees counterclockwise rotation is:

[tex](x,y) \to (y,-x)[/tex]

So, we have:

M' = (-2,3)

The rule of reflection over the x-axis is:

[tex](x,y) \to (x,-y)[/tex]

So, we have:

M" = (-2,-3)

Hence, the coordinates of M" are (-2,-3)

Answer:

get the inequality first ! x<44

Step-by-step explanation:

3/4x+8<41 ( subtract 8 from both sides. 8 cancels out. and 41-8=33 )

3/4x<33 ( multiply both sides by 4/3)

3/4 ×4/3 = 1

33×33 =44

x<44

and to graph it your line should have a open circle on 44 and point to the left.

Answer:

yes it can be scaline triangle

Answer:

the equation is y = 8x

Step-by-step explanation:

so rn we know that the y-intercept 0 so we can write:

y = mx

now to find the slope we need to use the equation y2 - y1/ x2 - x1

lets use the points

(2, 16) and (-2, -16) sooo

16 - (-16) / 2 - (-2)

32/4

8

1. Eight more than a number 14 -> 14 + 8 = 22
2. Number decreased by 12 is 9 -> 9 + 12 = 21
3. 20 subtracted from walters age is 24 -> 24 + 20 = 44
4. Ten more than twice as jose's age is 24 -> (24-10)/2 = 7
5. x + 15 = 2x -> x = 15

Answer:

yes

Step-by-step explanation:

For the lengths to be the sides of a triangle.

The sum of any 2 must be greater than the third.

8 + 11 = 19 > 14

8 + 14 = 22 > 11

11 + 14 = 25 > 8

Then the 3 lengths can form the sides of a triangle

Answer:

Yes, it can be the sides of a scalene triangle.

Step-by-step explanation:

Because the sides and the angles of a scalene triangle are different.

Answer:

Step-by-step explanation:

Answer:

angle(2) = 118 degree

angle(3) = 118 degree

angle(4) = 62 degree

Step-by-step explanation:

To find angle 2 :

[tex]62 + angle{2} = 180 \\ angle{2} = 180 - 62 = 118 \: degree[/tex]

The rule (head to head):

angle(2) = angle(3) = 118 degree

And the last one is angle(4) which is the same thing:

angle(4) = angle(1) = 62 degree

The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA

SOH = Sin is OPPOSITE / HYPOTENUSE

CAH = Cos is ADJACENT / HYPOTENUSE

TOA = Tan is OPPOSITE / ADJACENT

For example if we were to solve question 5

Sin T = 6 root 2 / 19

Cos T = 17 / 19

Tan T = 6 root 2 / 17

Repeat the steps for question 6

For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1

for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so

cos x = 9 / 18

to find x plug: cos^-1 (9/18) in the calculator

C) [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

Slope can be found using the change in y over the change in x

-> See attached, it is difficult to type out here

[tex]\frac{-5--2}{3--1} =\frac{-5+2}{3+1} =\frac{-3}{4}[/tex]

Giving us an answer of C) [tex]\frac{-3}{4}[/tex]

Answer:

[tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

The equation for slope is:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can plug the given coordinates into the equation:

[tex]Slope=\frac{-5-(-2)}{3-(-1)}=\frac{-5+2}{3+1}=\frac{-3}{4}=-\frac{3}{4}[/tex]

Known information:

Let us set up some variables for our terms:

Let us set up some equations in terms of our known information

Let us set up everything in terms of L, because in the first equation, we will be able to get rid of all the other variables but L allowing us to solve the equation:

              (S + M) + L = 24 --->   L + L = 24

              2L = 24

              L = 12

Since L = 12, we know that S = L - 2:

              S = L - 2 = 12 - 2 = 10

Since now we know that L = 12, and S = 10, and L = S + M:

              L = S + M

              12 = 10 + M

               M = 2

So our answer is 2, 10, 12

Hope that helps!
