chosen student took Form B and did not pass? Show ur work/explain in words what you did
A. 0.055
B 0.195
C. 0.305
D. 0.390

Answer:

36% of 240

=36/100*240

=6640/100

=86.4

Step-by-step explanation:

Answer:

£86.40

Step-by-step explanation:

36% = [tex]\frac{36}{100}[/tex] = 0.36 , then

0.36 × £240 = £86.40

Answer:

4/18

Step-by-step explanation:

Answer:

Option B

Step-by-step explanation:

Equation of the graph,

f(x) = x²

If the graph is translated 5 units to the right,

g(x) = f(x - 5)

Therefore, g(x) = (x - 5)²

If the function 'g' is translated 3 units up,

h(x) = g(x) + 3

Therefore, h(x) = (x - 5)² + 3

If the function 'h' is vertically compressed by a factor of [tex]\frac{2}{3}[/tex],

Then the new function will be,

k(x) = [tex]\frac{2}{3}(x-5)^2+3[/tex]

Option B will the correct option.

Answer:

Step-by-step explanation:

11 = 1

10 = 1

01 = 0

It is a puzzle.  It just take the term on the left side of the two digits.

Example : 24 = 2

               36 = 3

               49 = 4

Answer:

Step-by-step explanation:

(√10)²=10

1. (2 1/2)²=(5/2)²=25/4=6.25

2. (3 1/5)²=(16/5)²=256/25=10.24

3. 3²=9

4. (1/10)²=1/100=0.01

we see 10.24 is near to 10

so 3 1/5 is closest.

Step-by-step explanation:

keep in mind that, to get the inverse expression of any relation, we start off by doing a quick switcheroo on the variables, and then solve for "y", so let's do so,

Answer:

[tex]y = \frac{\sqrt{x+4} }{3}, \ y = -\frac{\sqrt{x+4} }{3}[/tex]

Step-by-step explanation:

To  find inverse we replace  and y first.

[tex]y = 9x^2 - 4 \ becomes \ x = 9y^2 -4[/tex]

[tex]Then \ solve \ for \ y\\\\9y^2 = x+ 4\\\\y^2 = \frac{x+4}{9}\\\\y = \pm \sqrt{\frac{x+4}{9}} \\\\y = \pm {\frac{\sqrt{x+4}}{3}[/tex]

Answer:

Step-by-step explanation:

Numbers 1 and 4 are perimeter questions so all you do is add up all the sides and the label is cm. For #2, this is an area problem and the area for a rectangle is length times width, so multiply the 2 together and the label is inches squared. For #3, the volume formula for a cube is side*side*side and the label for this is feet cubed. For #5, the area for a triangle is .5 times the base times the height, and the label is mm-squared. That should help you get all the answers on your wn. Very, very simple.

Answer:

[tex]IQR = 15[/tex]

Step-by-step explanation:

Given

I will answer this question with the attached plot

Required

The interquartile range (IQR)

This is calculated using:

[tex]IQR = Q_3 - Q_1[/tex]

On the second attachment, I identified Q1 and Q3 on the plot.

So, we have:

[tex]Q_3 = 40[/tex]

[tex]Q_1 = 25[/tex]

[tex]IQR = Q_3 - Q_1[/tex]

[tex]IQR = 40 - 25[/tex]

[tex]IQR = 15[/tex]

Answer:

[tex]y=x[/tex]

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]y=mx+b[/tex]

We're given that the slope of the line is 1. Plug this into the above equation

[tex]y=1x+b\\y=x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=x+b[/tex]

Plug in the given point (-7,-7)

[tex]-7=-7+b[/tex]

Add 7 to both sides to isolate b

[tex]-7+7=-7+b+7\\0=b[/tex]

Therefore, the y-intercept is 0. Plug this back into [tex]y=x+b[/tex]

[tex]y=x+0\\y=x[/tex]

I hope this helps!

Answer:

What is the value of x, if the area of ΔABC is 12√3 square cm ...

Step-by-step explanation:

maybe this link  helps you

Answer:

15 x 20 x 4 = 1,200

6 x 4 = 24, 24 divided by 2 ( x 1/2 ) = 12

12(area of 1 triangle) x 12(width) = 144

Formula area of a triangle:

B(base) x H(height) x 1/2(basically just dividing by 2)

Formula volume of a rectangular prism:

L x W x H

Answer:

1) 1200

2) 144

Step-by-step explanation:

1:

Volume Of A Cube: L * W * H

Substitute: 25 * 20 * 4

2:

Volume Of A Triangular Prisism: 0.5 * B * A * H

Substitute: 0.5(6 * 4) * 12

Answer:

Length of short side is 62 cm and length of long side is [tex]62\sqrt{3}[/tex] cm

Step-by-step explanation:

There's specific "rule" for 30-60-90 triangle

short leg will be x

long leg will be [tex]x\sqrt{3}[/tex]

hypotenuse will be 2x

So, when you know hypotenuse is 124 (2x)

To find short leg, you divide 124 by 2

short leg will be 62 (x)

To find long leg, you plug in the x (in this case it's 62)

long leg will be [tex]62\sqrt{3}[/tex]

Answer:

It is an Arithmetic sequence

Common difference = 3/4

Step-by-step explanation:

Determine whether the given sequence could be geometric, arithmetic, or neither. If possible identify the common ratio or common difference 1/2,5/4, 2, 11/4..

We are given the sequence:

1/2, 5/4, 2, 11/4.

We are to determine if this is an Arithmetic or Geometric sequence

Hence:

To determine if this is an Arithmetic sequence, we find the Common difference

Common difference = Second term - First term

= 5/4 - 1/2

Lowest Common Denominator = 4

= 5 - 2/4 = 3/4

or Third term - Second term

2 - 5/4

Lowest Common Denominator = 4

2/1 - 5/4

8 - 5/4

= 3/4

We have the same common difference.

To determine if this is an Geometric sequence, we find the Common ratio

Common ratio = Second term / First term

= 5/4 ÷ 1/2

5/4 × 2/1

= 5/2 = 2 1/2

or Third term /Second term

2 ÷ 5/4

2 × 4/5

= 6/5

= 1 1/5

It is not a geometric sequence

Therefore , the above sequence in the Question is an Arithmetic sequence.

Answer:

6558.75

Step-by-step explanation:

total value of 100 logs = total value of an average log x 100 total value of an average log = length of an average log x price per board foot

8.25 x 7.95 = 65.5875

65.5875 x 100 = 6558.75

Answer:

The absolute value function:

f(x) = |x|

is defined as:

f(x) = x              if x ≥ 0

f(x) = -x             if x < 0.

Then, knowing that the elevation of the diver is -380 ft

We can write the absolute value of the distance as:

|-380ft| = -(-380ft) = 380ft

This means that the diver is at a distance of 380 ft from sea level. (And because we know that the sign is negative, we can conclude that he is 380ft below sea level).

Answer:

you would be..80

Step-by-step explanation:

All you have to do is an addition equation

60 + 20 = 80

Step-by-step explanation:

angle 6 = 61° (definition of vertical angles)

angle 3 = 61° (definition of alternate interior angles)

angle 1 = 61° (definition of vertical angles)

angle 7 = 119° (definition of supplementary angles)

angle 5 = 119° (definition of supplementary and vertical angles)

angle 4 = 119° (definition of consecutive interior angles)

angle 2 = 119° (definition of vertical angles)

Answer: [tex]40h[/tex]

Step-by-step explanation:

Given

Speed of car is [tex]40\ mph[/tex]

We know, distance is given by

[tex]\text{Distance=}\text{speed}\times \text{time}[/tex]

Let h represents the number of hours

So, the distance traveled with speed [tex]40\ mph[/tex] in 'h' hours

[tex]\Rightarrow d=40\times h\\\Rightarrow d=40h[/tex]

So, the expression is given by [tex]40h[/tex]
