Area of circle:

2^2 = 4

4 x 3.14 = 12.56

Area of two circles:

12.56 x 2 = 25.12

Now we find circumference:

2 x 3.14 x 2 = 12.56

Now we multiply it by height:

12.56 x 8 = 100.48

Let's add the given areas now:

100.48 + 25.12 = 125.6 cm2 is your answer.

Step-by-step explanation:

Given

[tex]\angle W=90^{\circ}[/tex]

[tex]VW=32\ ft[/tex]

from the figure, we can write

[tex]\Rightarrow \tan v=\dfrac{UW}{VW}\\\\\Rightarrow \tan v=\dfrac{78}{32}\\\\\Rightarrow \tan v=2.437\\\Rightarrow v=\tan^-1(2.437)\\\Rightarrow v=67.68^{\circ}[/tex]

Answer:

2.5

Step-by-step explanation:

273/280 = 97.5%

2.5% are defective

If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects, There is a 2.5% chance of finding a defective headset.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

A manufacturer tests a certain number of the headsets that are produced each day.

If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,

The chance of finding a non-defective headset

= 273/280

= 97.5%

The chance of finding a defective headset

= 100% - 97.5%

= 2.5% are defective

The probability that the student will pick a ball that is either red, orange, or green is 0.75

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

Let the probability that the student will pick a ball that is either red, orange, or green be P

Now , the total number of balls in the container = 1000 balls

And , probability that the student will pick a ball that is either red, orange, or green can be calculated as the sum of the probabilities of picking a red ball, an orange ball, or a green ball. That is,

P(Red or Orange or Green) = P(Red) + P(Orange) + P(Green)

The probability of picking a red ball is 400/1000 = 0.4

The probability of picking an orange ball is 250/1000 = 0.25

And the probability of picking a green ball is 100/1000 = 0.1.

Therefore , P (Red or Orange or Green) = 0.4 + 0.25 + 0.1 = 0.75

Hence , the probability is 0.75

Answer:377 /4  = 94 and 1 / 4  =94.25

Step-by-step explanation:

Subtract

95 − 3 /4

 = 377 / 4

Convert integer to fraction

95 = 95 / 1

Find common denominator

95 over 1

− 3 over 4

= ( 95 × 4 ) over ( 1 × 4 )

 − ( 3 × 1 ) over ( 4 × 1 )

= 380 over 4

 − 3 over 4

4 is the least common multiple of denominators 1 and 4. Use it to convert to equivalent fractions with this common denominator.

Subtract

380 over 4

− 3 / 4

= ( 380 − 3 ) / 4

= 377 /4

Simplify

377 / 4

= 94 and 1 /494

Reduce fraction to lowest terms

1 is the greatest common divisor of 377 and 4. The result can't be further reduced.

Step 2 of 2: Simplify, sub-step b: Convert improper fraction to mixed number.

Convert improper fraction to mixed number

377 /4

= 94 1 /4

377 ÷ 4 = 94 remainder 1

By writing the whole number as a fraction, we will see that the solution is 377/4

Here we want to take the difference between a whole number and a fraction:

95 - 3/4

To do this, we need to write the whole number as a fraction, to do it, we multiply and divide it by 4:

95 = (4/4)*95 = 380/4

Now we rewrite our expression as:

95 - 3/4 = 380/4 - 3/4 = 377/4

This is the solution of the expression.

Answer:B) 150

Step-by-step explanation:

Area of rec= L×W

= 10×30= 300

Area of shaded area= 1/2 Base× Height

1/2×10×15=75

75×2 = 150

Area of unshaded part= 300-150= 150

Answer:

150 Square Units

Step-by-step explanation:

(Sorry if I become confusing)

The base of the triangles is 10 units.

The height of the triangles is 15 units.

The formula I used was A=[tex]\frac{1}{2}bh[/tex]

b=base and h=height A=area

A=[tex]\frac{1}{2}(10)(15)[/tex]

A=[tex]\frac{1}{2}(10)(15)[/tex]=75

A=75

Multiply by two to get the area for both triangles.

75·2=150

Answer: the answer is b

Step-by-step explanation:

Given:

The graphs of f(x) and g(x).

The function f(x) is given by:

[tex]f(x)=x^2[/tex]

The graph of g(x) passes through the point (2,12).

To find:

The function g(x).

Solution:

From the given graph it is clear that the vertex of both function f(x) and g(x) is at (0,0). It means the graph of f(x) is not translated. It means the graph of f(x) is only vertically stretched to get the graph of g(x). So,

[tex]g(x)=kf(x)[/tex]

Where, k is the stretch factor.

[tex]g(x)=kx^2[/tex]               ...(i)

The graph of g(x) passes through the point (2,12). Putting [tex]x=2, g(x)=12[/tex], we get

[tex]12=k(2)^2[/tex]

[tex]12=k(4)[/tex]

[tex]\dfrac{12}{4}=k[/tex]

[tex]3=k[/tex]

Putting [tex]k=3[/tex] in (i), we get

[tex]g(x)=3x^2[/tex]

Therefore, the correct option is A.

Answer:

A reflection in the line y = -2, then a translation 2 units right.

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserves the shape and size of the object. Rotation, reflection, translation are rigid transformation whereas dilation is not a rigid transformation.

Any transformation regarding dilation changes the side length of the object and hence the area.

From the question, only one option is right. The rest options are not right because they involve dilation. The correct option is:

A reflection in the line y = -2, then a translation 2 units right.
