Answer:

A, [tex]\sqrt{17}[/tex]

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + b^2 = 9^2

64 + b^2 = 81

b^2 = 17

b = [tex]\sqrt{17}[/tex]

Answer:

by pythagoras theorem

9² = 8² + x²

x² = 81 - 64

x² = 17

x = root 17

option A

Answer:

Exact form: [tex]\frac{512}{343}\\[/tex]

Decimal Form:1.4927

Mixed Number Form: 1 [tex]\frac{169}{343}[/tex]

Answer:

Variance is the difference between a Budgeted Amount and the Actual Amount. In terms of expenses, if the Budgeted amount is more than the Actual amount, the variance is Favorable because less was spent than was supposed to be spent.

The reverse is true.

Variance = Budgeted Amount - Actual amount

= 255 - 225

= $30

Percentage = Variance / Budgeted amount

= 30/255

= 11.76%

The variance is FAVORABLE because the actual amount was less than the budgeted amount.

Answer:

x=-2

Step-by-step explanation:

R=1

Y=1

So the equation is

4x+9=1

4x=1-9

4x=-8

x=-8/4

x=-2

Answer:

x=-2

Step-by-step explanation:

R=1

Y=1

So the equation is

4x+9=1

4x=1-9

4x=-8

x=-8/4

x=-2

Answer: I think its 131.19, but not too sure.

Step-by-step explanation:

To find the speed, you would do distance/time, so I added 300 and 7. I got 307, then I divided 307 (distance) from 2.34 (time). I got 131.19

Do you want the speed of both cars? then the answer would be:

(300)- first car= 128.20

(307)- second car= 131.19 (if you need to round this answer, it would be 131.2)

Answer:

side DA = side CB = slope is Undefined

side DC = side AB = slope is 0

Step-by-step explanation:

To find the slope we use the following

m = [tex]\frac{(y2 - y1)}{(x2 - x1)}[/tex]

The slope for side DA is the same as side CB; also their value for x value will be the same on the line; leaving the bottom of the slope equation at 0.

That means that side DA = side CB = slope Undefined

The slope for side DC is the same as side AB; also their value for y value will be the same on the line; leaving the top of the slope equation at 0.

That means that side DC = side AB = slope 0

Answer:

The answer should be y = -[tex]\frac{3}{2}[/tex][tex]x[/tex] + 8, but its not one of the answers, so check the question again.

Step-by-step explanation:

If the second line is parallel, then the gradient will be the same:

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

Find what c is (y-intercept) by inputting the given point into the equation (4,2):

2 =  (-[tex]\frac{3}{2}[/tex] x 4) + c

2 = -6 + c

c = 8

Answer:

34-5x

Step-by-step explanation:

Answer:

1.) 3:2 → length = 3cm ; width = 2cm

2.) 6:4 → length = 6cm ; width = 4cm

3.) 9:6 → length = 9cm ; width = 6cm

Step-by-step explanation:

The ratio 3:2 is length:width. This means that if you were to simplify the values by a common factor, the result would always be [tex]\frac{3}{2} = \frac{length}{width}[/tex].

To find three dimensions, pick any random three numbers and multiply one by one to both numerator and denominator:

[tex]1,2,3\\\\\frac{3}{2}(\frac{1}{1} )= \frac{3}{2} \\\\\frac{3}{2} (\frac{2}{2} )=\frac{6}{4}\\\\\frac{3}{2} (\frac{3}{3} )=\frac{9}{6}[/tex]

Convert the given ratios to length and width:

1.) 3:2 → length = 3cm ; width = 2cm

2.) 6:4 → length = 6cm ; width = 4cm

3.) 9:6 → length = 9cm ; width = 6cm

If you were to simplify each, the result would be 3:2.

Answer:

[tex]y=\frac{7-3x}{j}[/tex]

Step-by-step explanation:

First, subtract 3x. This leaves you with jy=7-3x. Then, divide by j, leaving you with [tex]y=\frac{7-3x}{j}[/tex] .

Answer:

4.8 x 10^12

Step-by-step explanation:

Move the decimal to the second space so:

4.800000000000

Then count how many spaces the decimal moved so:

12

Then get rid of the 0s and add the x 10^12 so: 4.8 x 10^12.

Step-by-step explanation:

4,800,000,000,000 = 4.8 x 10^12

This is a conversion to standard form question. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)

Answer:

no, it is rational

Step-by-step explanation:

a rational number is one that can be expressed as division of an integer by a nonzero integer. So it is rational, not irrational.

Answer:90

Step-by-step explanation:Hi.

Here is your answer---

Let the number of Students in a school be x.

Thus,Number of Girls = 3/7 of the total Students

= 3/7 of x

= 3x/7

We know,

Number of Boys + Number of Girls = Total Students.

64 + 3x/7 = x

64 = x - 3x/7

64 = (7x - 3x) /7 [Taking L.C.M.]

64 × 7 = 4x

x = 60 × 7

x = 420

Total number of Students in a school is 420.

Thus, Number of Girls = 3/7 × x

= 3/7 × 420

= 90

Thus, the number of Girls in a school is 90.

Find full question attached

Answer and explanation:

The perimeter of a rectangle is the sum of all the sides of the rectangle.

From the question(attachment) we can see the length and width of the rectangle given. Therefore, to find the perimeter of the rectangle we add up the length(2 sides) and the width(2 sides).

The width = 6x +1

The length = 2x-5

Therefore the equation of the perimeter 120 :

6x-1+6x-1+2x+5+2x+5 =120

Also same thing as

2(6x-1)+2(2x+5)=120

Hence, correct option is C
