How do I figure out the area and perimeter of these shapes and how do you figure out the unknown side? Q9

Answer: I believe is is C, rotations and translations

Step-by-step explanation:

This is because a congruent figure is one that has the same side lengths and angle measures.

Stretches and dilations are non-rigid transformations which change the length of the sides of a shape. While rotations, transformations, and reflections are rigid transformations which preserve angle measure and side length.

So, while a shape can be similar using stretches and dilations, they cannot be congruent.

Answer:

$7.25 + $4.25 + 6.00 = $17.50

Step-by-step explanation:

7.25 + 4.25= 11.50 + 6.00= 17.50

Answer:

I think they should be taught first so that later on they can use it, and also just in case they forget to know how to multiply or divide they can sorta use addition and subtract for it.

Another reason is that it is easier and since they are teaching it to younger kids it would be helpful to start off a bit easy.

Answer:

Between 8 and 9

Step-by-step explanation:

We know that the equation for the volume of a cone is V = 1/3(pi)r^2h

So,

V = 1/3(pi)r^2h

150pi = 1/3(pi) r^2 h --> the pi's cancel out and then we are left with...

3(150) / h = r^2

Plug in values and simplify --> r = sqrt.(450/6) and you end up getting 8.66025403784.

Answer:

13 is a solution.

Step-by-step explanation:

[tex]7w = 94 \\ \frac{7w}{7} = \frac{94}{7} \\ w = 13.42 \\ [/tex]

13.42 ≈ 13

Step-by-step explanation:

F = 9(11) + 19 [ z = 11]

= (9 × 11) + 19

= 99 + 19

= 118

H = 11(11) - 3 [z = 11]

= 11 ×11 - 3

= 121 - 3

= 118

Answer:

Angle F and H are equal, and Angle E and G are equal. EFGH is a parallelogram because opposite angles are congruent.

Step-by-step explanation:

Step 1:

Insert z=11 into (9z+19), angle F,  and (11z-3), Angle H,  to find the angle lengths.

9(11)+19=118

11(11)-3=118

We see that they are the same angles! In step 2, we see the same thing happen. Note that the definition of parallelograms is that opposite sides and angles are equal.

Sentence completion: Angle F and H are equal (We see that in step 1), and  Angle E and G are equal (Shown in step 2, which is done for you.) EFGH is a parallelogram because opposite angles are congruent. Hope this helps!

Answer:

0.16

Step-by-step explanation:

2.88 divided by 18 = .16

Answer:

0.16

Step-by-step explanation:

2.88/18 = 0.16

because you divide the total cost of the box of dog biscuits with the total amount of biscuits that are in the box and then that gives you 0.16.

So each dog biscuit cost $ 0.16

How to find the area in terms of pi?

Answer: First divide the circumference by Pi to give the diameter of the circle (27 divided by 3.14 = 8.59...). Now halve the diameter to give the radius (8.59 divided by 2 is 4.29...). Now use Pi*r^2 to find the area of the circle (Pi times 4.29^2 = 58.0 cm^2 to 1 decimal place)

The given measure of the angle in standard form, -17•π/6, gives;

A. The terminal side of the angle, -17•π/6 is located in the third quadrant

B. The reference angle is 150°

C. The values of the six trigonometric functions are;

Trigonometric ratios relates an angle to the ratio of the sides of a right triangle containing the angle.

A. The given measure of the angle is -17•π/6

2•π radians = 360°

π radians = 180°

-17•π/6 = -(2+(5/6))•π

Therefore, the terminal side makes one complete revolution clockwise starting from the x–axis, it then makes a further -(5/6)•π, clockwise, which is -(5/6)×180° = -150°

The terminal side therefore moving clockwise, passes the fourth quadrant and stops at the third quadrant at -150°, which is equivalent to 210° clockwise rotation from the x–axis

B. The reference angle is the acute angle between the terminal side and the x–axis

Therefore;

C. The six trigonometric functions are;

cosine, sine, tangent, cotangent, secant, and cosecant

The solution to the system of equation is (4, 0)

Given the system of equation expressed as:

y=-x+4

y=x-4

Equate both expressions to have;

-x + 4 = x - 4

collect the like terms

-x - x = -4- -4

-2x = -8

x = 4

Since y = x - 4

y = 4-4

y = 0

Hence the solution to the system of equation is (4, 0)
