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.

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

Answer:

-4742

Step-by-step explanation:

-17 + -68+(+56) -5333+620

-5418+58+620

-5418+676

-4742

:) Hope this helped

Answer:

-4742

steps :

-17 - 68 = -85

-85 + 56 = 29

29-5333= -5304

-5304+620 = -4742

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.

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.

Hope it helps.

Answer:

[tex]a_{n}[/tex] = 5[tex]a_{n-1}[/tex]

Step-by-step explanation:

The sequence has a common ratio r between consecutive terms, that is

r = 10 ÷ 2 = 50 ÷ 10 = 250 ÷ 50 = 5

Thus the sequence is geometric with recursive formula

[tex]a_{n}[/tex] = 5[tex]a_{n-1}[/tex]

Answer:

A. (9,-5)

Step-by-step explanation:

Translation down is -2 to the y coordinate, which is (5,-5). Then you translate it right 4 units, which is +4 to the x coordinate, so the final coordinate is (9,-5).

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.

Answer:

Step-by-step explanation:

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.

Step-by-step explanation:

for 1 year it will charge 100$ and if you rent 20 toys in that year the toys will cost 100$ as well so if you add 100+100 you get 200 so the answer is 200$

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.

Answer:

Addition expression: 58+(-27)

Subtraction expression: 58-27

First, we'll solve A.

2 x2 = 4

3 x2 = 9

3x2=6, not 9.

So it is not A.

5 x2 = 10

7 x2 = 11

7x2=14, not 11.

So B. is out too.

It isn't D. because 12/9 is improper and 3/4 isn't.

So C. is left.

4 x2 = 8

6 x2 = 12

hope it helps!

===============================================

Explanation:

Let's go through the answer choices

-----------

Choice A.

Assume that the given equation here is correct. If so, then we can cross multiply to get

2/3 = 4/9

2*9 = 3*4

18 = 12

The last equation is false, so the first equation is also false. Choice A is not the answer.

-------------

Choice B.

We could do the similar trick as with choice A, but I'll use another method.

Use your calculator to find that

5/7 = 0.714 approx

10/11 = 0.909 approx

We get different decimal values for each fraction, so there's no way the two sides are the same. Choice B is crossed off the list.

-------------

Choice C.

I'll use another method here. Note how the denominators are 6 and 12, and how 6*2 = 12. If we multiply top and bottom of 4/6 by 2, then

(4/6)*(2/2) = (4*2)/(6*2) = 8/12

meaning that 4/6 = 8/12 is a true equation. We can see it through cross multiplication

4/6 = 8/12

4*12 = 6*8

48 = 48

or we could use our calculator to find that

4/6 = 0.667 approx

8/12 = 0.667 approx

Another calculator trick you can use is type in "4/6 - 8/12" without quotes and you should get 0 (or very close to it) as a result. This is using the idea that if x = y, then x-y = 0.

Choice C is the answer

----------------

Choice D.

Since we found the answer, we technically don't need to check choice D. But let's do so anyway.

Right off the bat, we know that 3/4 is less than one, while 12/9 is greater than one. So there's no way 3/4 = 12/9 could be true.

Answer:

we know that, 1miles/hour = 0.45m/s

or, 1meters/second = 1/0.45

1m/s = 2.22222222222

Step-by-step explanation:

Then,

72.0 meters/second = 72.0*2.22222222222

                                  =160 miles per hour.
