square root of 2025 by prime factorisation​

Answers

I can give you the easy answer of 45, but let's use prime factorization.

What number looks like it divides into 2025 easily?

Your first answer was probably 5.

2025 divided by 5 is 405.

What number looks like it divides into 405 easily?

It was probably 5 again.

405 divided by 5 is 81.

Now hopefully you know that the square root of 81 is 9.

We can bring these all out of the radical.

[tex]\sqrt{2025}[/tex]

[tex](9*5)\sqrt{1}[/tex]

We know that [tex]\sqrt{1}=1[/tex], so we can simplify this whole expression down to the outside terms, which multiply to 45.

Brad and Nora both went bowling last weekend, but not together. Brad went during open bowling time, paying $2 for shoe rental and $3 per hour. Nora went on family night, when each hour was $1 and shoe rental was $6. As it turned out, they played for the same number of hours and spent the same amount. How many hours did each one bowl?

Answers

Brad paid $2 for shoe rental. This variable stays the same. If he bowled for two hours it would be $3x2hr. That would be (3x2)+2=$8. Nora paid $6 for shoe rental. This variable stays the same. If she bowled for two hours that would be $2. 2+6=$8. The answer is that they each bowled for two hours. (:

Answers

Answer:

Answer: Option D.

Step-by-step explanation:

Hey there!!

Here, To find the equation of a st.line passing through point (3,1) is :

[tex](y - 1) = m1(x - 3)[/tex]

It is the first equation.

Given, Another equation is:

[tex]y = \frac{2}{3} x + 1[/tex]

It is 2nd equation.

Comparing the 2nd equation with y = mx+c we get,

Slope (m2) = 2/3.

As per the condition of parallel lines,

m1 = m2 = 2/3.

Putting, the value of m1 in equation 1st we get,

[tex](y - 1) = \frac{2}{3} (x - 3)[/tex]

or, 3 (y-1) = 2(x-3)

or, 3y - 3 = 2x - 6

[tex]y = \frac{2x - 6 + 3}{3} [/tex]

[tex]y = \frac{2}{3} x - 1[/tex]

Diving-3/3 = -1.

Therefore, y = 2/3 x - 1 is the required equation.

Jason has 144 feet of material to build a fence around a rectangular garden on his property. If the width of the fence must be 9 feet, what is the length of the fence in yards if he uses all 144 feet of material

Answers

Answer:

Length = 63 feet

Step-by-step explanation:

concept used:

perimeter of rectangle = 2( length + width)

____________________________________________

Given that Jason has 144 feet of material and all is used in building fence.

It means that perimeter of fence is 144 feet.

2. Width of fence = 9 feet

let the length be x

perimeter of rectangle = 2( length + width)

then perimeter of fence will be = 2(9+x)

As given above perimeter of fence is 144 feet.

2(9+x)  = 144

=> 9 + x = 144/2 = 72

=> x = 72 - 9 = 63

Length = 63 feet.

What is the absolute value of |5+8a|=53?

Answers

Answer:

a = 6 or a = -58/8

Step-by-step explanation:

I think you meant to ask us to solve for a.

There are two cases to solve for:

5 + 8a = 53 or -(5 + 8a) = 53

8a = 48 or 5 + 8a = -53

a = 6 or 8a = -58

a = 6 or a = -58/8

Slope of line AB:
Slope of line CD:
Are the lines parallel (yes or no):

Answers

Step-by-step explanation:

Hey there!!

Let me simply clear you.

Given,

AB: 2y+2x =8.

Let's take the equation in slope intercept form.

2y = -2x +8

[tex]y = \frac{ - 2x}{2} + \frac{8}{2} [/tex]

[tex]y = - 1x + 4[/tex]

Comparing the equation with y= mx+c, we get;

Therefore, slope of AB is -1.

Now,

Again, the another equation is,

y + x = 2

y = -x+2

Comparing, the equation with y = mx + c.

Therefore, slope of CD = -1

For parallel lines, m1=m2.

slope of AB (m1) = -1

slope of CD(m2)= -1

As m1= m2 {True}.

Therefore, They are parallel to eachother.

Tiana has already taken 1 page of notes on her own, and she will take 1 page during each hour of class. In all, how many hours will Tiana have to spend in class before she will have a total of 43 pages of notes in her notebook?

Answers

Answer:

42 Hours.

Step-by-step explanation:

As an equation where y is the total pages and x is hours of class:

y=1+1x since she started with 1 page and does 1 page per hour.

Setting the total pages she needs as 43 (y=43) we get:

43=1+1x

Subtract one on both sides

42=1x

The 1 doesn't need to be written so

x=42

Therefore, it'll take her 42 hours to write all those notes.

Two angles form a linear pair. the measure of one angles is 15° less than 2/3 the measure of the other angle. Write and solve an algebraic equation to find the measure of each angle. I need help! someone plz help me!

Answers

Answer:

First angle = 117 degrees.

Second angle = 63 degrees.

Step-by-step explanation:

If two angles are a linear pair, then their measures must add up to 180°. A straight line has a measure of 180°.

If we let one angle = x, then the other angle is (2/3)x - 15

Now we can form the following equation:

x + (2/3)x - 15 = 180

(5/3)x = 195

5x = 585

x = 117

Therefore, one angle is 117 degrees, and the other angle is (2/3 * 117) - 15 = 78 - 15 = 63 degrees.
