Answer:

Step-by-step explanation:

so basically when we write all three of the expressions in one fraction we get the same answer for all three multiplications.

a. (3/4)*7=(3*7)/4

b. 7*(3/4)=(7*3)/4

c. 3*(7/4)=(3*7)/4

when we change the place of the values that are being multiplied the value of the multiplication does not change, that's why they will be have the same answer and when we multiply all the operations, we get the same value as the answer.

1) Rotation    

2) Reflection

3)Dilation

4) Rotation

5) Reflection

6) Translation

7) Rotation

Step-by-step explanation: :

 Reflection is a flip.

Rotation turns a figure through an angle about a fixed point called the center.

Translation "slides" an object a fixed distance in a given direction.

Dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

28 + 35 + 42 + 49 + 56 + 63 + 70 = 343

Answer:

343

Step-by-step explanation:

28+35+42+49+56+63+70          We are asked to find the sum, so we add all the numbers in the series.

28+35+42+49+56+63+70 = 343

Answer:

A. y = -⅓x + 3

Step-by-step explanation:

Find the equation of the graph bin slope-intercept form, y = mx + b. Where,

m = slope = ∆y/∆x

Using two points on the line, (0, 3) and (3, 2),

Slope (m) = (2 - 3)/(3 - 0) = -1/3

m = -⅓

b = y-intercept = 3 (the y-coordinate of the point where the line crosses the y-axis)

✅To write the equation, substitute m = -⅓ and b = 3 into y = mx + b

Thus:

y = -⅓x + 3

Answer:

x - y + y =x is your answer hope it helps

Answer:

12.8

Step-by-step explanation:

imagine a right triangle in the middle,

base: 16 ÷ 2 = 8 cm, height: 10 cm, side: s

10² + 8² = s²

=> s = √(10² + 8²)

=> s = √(100 + 64)

=> s = √164

=> s ≈ 12.8

Answer:

The 4th cone

Step-by-step explanation:

Hello, the answer to your question is the 4th cone; the cone with its bottom half facing skyward.  If you are familiar with plane symmetry, this question is fairly simple.  Since the topmost cone has its bottom half facing downward, it would only be logical to choose the cone that forms mirror halves (superimpose) when paired.  

Hope this helps.

Answer:

The answer is "0.0023 and Choice a"

Step-by-step explanation:

In point a:

The central limit theorem:

[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]

In point b:

The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

Answer:

a) x = 8y

b) x = 32 + 4y

c) 8y =  32 + 4y

Step-by-step explanation:

-4y     -4y

8y = 32 + 4y

÷4    ÷4

4y = 32

y = 32

The expression represents the cost for a non-member to attend y classes is x=8y.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class.

Let y represent the number of karate classes attended.

a) The cost for a non-member to attend y classes is

Non-members pay $8 per class.

So, the expression is 8y

b) The cost for a member to attend y classes is

Club members are charged a one-time membership fee of $32 and pay $4 per class.

Now, the expression is 32+4y

c) Set the two expressions equal to each other, that is

8y =32 + 4y

8y-4y=32

4y=32

y=8

Therefore, the expression represents the cost for a non-member to attend y classes is x=8y.

Answer:

7. [tex]c = 15.81[/tex]

8. [tex]b = 16[/tex]

Step-by-step explanation:

Required

Determine the third sides

(7): We have

[tex]b = 5[/tex]

[tex]a = 15[/tex]

[tex]c=??[/tex]

To find c, we make use of Pythagoras theorem

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

[tex]c^2 = 5^2 + 15^2[/tex]

[tex]c^2 = 250[/tex]

[tex]c = \sqrt{250[/tex]

[tex]c = 15.81[/tex]

(8): We have

[tex]c = 20[/tex]

[tex]a = 12[/tex]

[tex]b = ??[/tex]

To find c, we make use of Pythagoras theorem

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

[tex]20^2 = 12^2 + b^2[/tex]

[tex]400 = 144 + b^2[/tex]

[tex]b^2 = 400 - 144[/tex]

[tex]b^2 = 256[/tex]

[tex]b = \sqrt{256[/tex]
