are my answers correct if not can you explain why please?

Answer:

ok i did one of these before it was the 2nd or 3rd one

Answer:

I also just noticed that is saying construct a segment of the lenght of both of them so after you have both lenght measure them draw AB close point get CD and trace it over start from B and there you have the big segment which is made of both of them AB + CD

:)

Step-by-step explanation:

So basically get your compass and start by these steps

first get the total lenght of AB lets say its 100

when you go to make CD angle all you have to do

its trace same line and there you got both points same sizes

I hope that helped.

28 * 2 = 56.

Answer:

0.03213586

Step-by-step explanation:

Answer:

The amount between each. Since you didn't attachment any further information like the amount of M, N, and P or a graph chart- I'll only be able to give an example.  

Let's say M is equal to 3, N is equal to 1, and P is equal to 2. All together these spaces add up to 6 which can be evenly space out or distributed unevenly.  

Like M:N= 3:1 or N:P = 1:2. As you can tell all together (all you have to do is add 3&1 or 1&2) you'll get the result of 4 or 3 and they aren't similar. Let me know if this helps!  I know sometimes seeing technically terms and numbers can be difficult so I tried to explain with words as best I could. Good luck to you.

Answer:

28,500,000 into scientific notation is 2.85 x 10⁷

2.85 x 100 in scientific notation is 2.85 x 10²

if you mean the multiplication symbol, it just means to multiply. otherwise, there i don't see an x anywhere else

Answer: a=4b/5

Step-by-step explanation:

To solve for a, we want to use algebraic properties to isolate a.

3a+2b=6b-2a               [add both sides by 2a]

5a+2b=6b                     [subtract both sides by 2b]

5a=4b                           [divide both sides by 5]

a=4b/5

Now, we have found that a=4b/5.

Answer:

33.634 ; 134.536 ; d = √[(50t)² + (45t)²]

Step-by-step explanation:

Given the following :

Toyota Prius = East at 50mph

Dodge Circuit = South at 45mph

Distance apart after 30 minutes :

Distance = speed * time

Distance moved by Prius = ( 50mph × 0.5hr) = 25 miles

Distance moved by Circuit = ( 45mph × 0.5hr) = 22.5 miles

Hence Displacement after 30 minutes :

d = √(25² + 22.5²)

d = √625 + 506.25

d = √1131.25

d = 33.634 miles

Distance apart after 2 hours :

Distance = speed * time

Distance moved by Prius = ( 50mph × 2hr) = 100 miles

Distance moved by Circuit = ( 45mph × 2hr) = 90 miles

Hence Displacement after 2 hours :

d = √(100² + 90²)

d = √10000 + 8100

d = √18100

d = 134.536 miles

Distance d in miles after t hours :

d = √[(50t)² + (45t)²]

Answer: 0.1587

Step-by-step explanation:

Given : The distribution of number of purchases per hour is approximately normal with mean 1,200 purchases and standard deviation 200 purchases.

i.e. [tex]\mu=1200,\ \ \sigma=200[/tex]

Let X denotes the number of purchases per hour.

Then ,

[tex]P(X>1400)=P(\dfrac{X-\mu}{\sigma}>\dfrac{1400-1200}{200})\\\\=P(Z>1)\ \ \[Z=\dfrac{X-\mu}{\sigma}]\\\\=1-P(Z<1)\ \ \ [P(Z>z)=1-P(Z<z)]\\\\\ =1-0.8413\ \ [\text{By p-value table}]\\\\= 0.1587[/tex]

So, the proportion of hours will the number of purchases at the online store exceed 1,400 =0.1587

To find the zero of a function, we have to set f(x) equal to 0

0 = -3x + 1

Subtract 1 from both sides.

-1 = -3x

Divide both sides by -3

1/3 = x

The requried, expression to find the value of the given expression when x =-2 and y = 5 is 3²(-2)⁶/5⁴. Option A is correct.

In order to remove pointless terms, factors, or operations from an expression, arithmetic, and algebraic principles are applied. The objective is to get an expression that is simpler to use, manipulate, or solve. For instance, factoring, merging like terms, or applying the distributive property can all be used to simplify an algebraic statement.

Here,
Given expression,
= (3x³y⁻²)²

To find the solution of the above expression given value of x and y,
= (3(-2)³(3)⁻²)²
= (3²(-2)⁶/3⁴)

Thus, the required expression to find the value of the given expression when x =-2 and y = 5 is 3²(-2)⁶/5⁴. Option A is correct.

Answer:

2.555555 ....

Step-by-step explanation:

2 5/9 is a mixed number.  

Use your calculator to divide 9 into 5, to find the value of 5/9.  Then add 2 to the result:

5/9 = 0.5555555 (repeating fraction)

Adding 2, we get:

2.555555 .... (repeating fraction)

Answer:

A' (3, - 7 )

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ) , thus

A(3, 7 ) → A'(3, - 7 )

Answer:

(i) 2197

Step-by-step explanation:

(i) 13^3

=  (10+3)^3

=  10^3 + 3^3 + 3(10)(3) (10+3)

=  1000 + 27 + 90(13)

=  1027 + 1170

= 2197

Answer:

Greatest common factor (GCF) of 60: 223

Greatest common factor (GCF) of 108: 22333

The Greatest Common Factor (GCF) is:   2 x 2 x 3 = 12

Step-by-step explanation:

To get the Greatest Common Factor (GCF) of 60 and 108 we need to factor each value first and then we choose all the copies of factors and multiply them.
