Find the area of each round your answer to the nearest tenth

Answer:

105.12

Step-by-step explanation:

Find the area of the rectangle (8 x 10 = 80)

Find the area of the whole circle (3.14 x 4^2 = 50.24)

Divide the area of the circle by 2 since it is a semi circle (50.24 / 2 = 25.12)

Add the area of the two (25.12 + 80 = 105.12)

Answer:

$94.314

Step-by-step explanation:

Given data

Commission = 12%

Sale= $785.95

Let us find 12% of  $785.95

=12/100* 785.95

=0.12* 785.95

=$94.314

Hence she earns $94.314

Answer:

Step-by-step explanation:

y = 4 - 3x + x^2 is to be rewritten in standard form.  To do this, rearrange the terms in order of powers of x, from highest to lowest.

y = 4 - 3x + x^2 becomes y = x^2 - 3x + 4

Answer:

x=70

Step-by-step explanation:

All the angles in a triangle have to add up to 180. 40 degrees is already taken up so there is 140 degrees left. There are 2 remaining angles, so 140/2=70. x=70.

Hope this helps!

Answer:

70

Step-by-step explanation:

all the angles add up to 180

180= 40 +x +x

180-40=2x

140=2x

140/2=x

x=70

Answer:

x=80* y=20* and X=100*

Step-by-step explanation:

If we assume PQ || OR then by alternate interior angles x is equal to 80 degrees and y is equal to 20 degrees.

We know that a triangle adds up to 180 degrees.

Angle ROX and XRO add up to 100 degrees. Leaving RXO equal to 80 degrees. (180-100=80).

By opposite angles, QXP is equal to 80 degrees also.

Then we are left with solving for X.

Supplementary angles add up to 180 degrees.

Subtract angle OXR from 180 and we are left with angle OXP = X = 100 degrees.

Answer:

2nd and 4th are parallel

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3y + x = 5 ( subtract x from both sides )

3y = - x + 5 ( divide terms by 3 )

y = - [tex]\frac{1}{3}[/tex] x + [tex]\frac{5}{3}[/tex] ← in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

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

x - 3y = 12 ( subtract x from both sides )

- 3y = - x + 12 ( divide terms by - 3 )

y = [tex]\frac{1}{3}[/tex] x - 4 ← in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

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

y = 3x - 2 ← in slope- intercept form

with slope m = 3

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

6y - 2x = 7 ( add 2x to both sides )

6y = 2x + 7 ( divide terms by 6 )

y = [tex]\frac{1}{3}[/tex] x + [tex]\frac{7}{6}[/tex] ← in slope- intercept form

with slope m = [tex]\frac{1}{3}[/tex]

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

Parallel lines have equal slopes.

The 2nd and 4th have equal slopes and are parallel

The factorization of x2 - 6x + 5 is (x - 1)(x -5)

From the graph, the zeros of the function are:

x = 1 and x = 5

Set the zeros to 0

x - 1 = 0 and x - 5 = 0

Multiply the zeros

(x - 1)(x -5) = 0

Hence, the factorization of x2 - 6x + 5 is (x - 1)(x -5)

Answer:

The given table is

   6                 9.00

It means the points on the graph are (1,2), (2,3.50), (3,5), (4,6.50), (5,8) and (6,9).

The graph 1 represents all the above mentioned point, therefore option 1 is correct.

According to the graph 2, at quantity 6 the price of flower is 12, which is not correct. Therefore option 2 is incorrect.

The quantity of flower is always a whole number. So the graph is defined on the whole numbers only. It means the graph is a scatter plot instead of a curve of a straight line.

Step-by-step explanation:

(5/6) itself is less than 1 (but greater than 0).  Thus, anything multiplied by (5/6) will result in a smaller-by-magnitude quantity.

For example, (5/6)(3/4) is LESS than 3/4 because 5/6 is greater than zero but less than 1.

The fraction 5/6 is less than one anything multiplied to this number will be less than 1.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the fraction is 5/6.

5/6 is less than 1 on its own (but greater than 0). Anything multiplied by (5/6) will provide a magnitude-less result. Because 5/6 is more than 0 but less than 1, it can be shown that (5/6)(3/4) is less than 3/4.

Therefore, the fraction 5/6 is less than one anything multiplied to this number will be less than 1.

Answer:

the answer is given on the picture

The number of people like only coffee is 30 and the number of people like only tea is 55.

A Venn diagram is a diagram that helps us visualize the logical relationship between sets and their elements and helps us solve examples based on these sets. A Venn diagram typically uses intersecting and non-intersecting circles (although other closed figures like squares may be used) to denote the relationship between sets.

Let T=tea and C=coffee

n(T)=80

n(C)=55

n(T∩C)=25

People did not like both tea and coffee=30

ii) Number of people surveyed

n(T∪C)=n(T)+n(C)-n(T∩C)

= 80+55-25

= 110

Then,

n(∪)=n(TUC)+People did not like both tea and coffee

= 110+30

= 140

iii) Number of people like only Tea

=n(T)-n(T∩C)

=80-25

=55

iv) Number of people like only coffee

=n(C)-n(T∩C)

= 55-25

= 30

Therefore, the number of people like only coffee is 30 and the number of people like only tea is 55.

Explanation:

We have two similar triangles here, so we can set up the proportion below to solve for x

5200/(5200+6500) = 5600/x

5200/11700 = 5600/x

5200x = 11700*5600 .... cross multiply

5200x = 65,520,000

x = (65,520,000)/(5200)

x = 12,600 which shows why the answer is choice D

side note: 12,600 ft = 2.386 miles approximately

The plane’s distance from point A when it reaches point C is 12600 feet.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

From the figure,

The two triangles are similar.

This means,

The ratio of its corresponding sides is equal.

So,

(5200 + 6500) / 5200 = (5600 + BC) / 5600

Solve for BC.

(5200 + 6500) / 5200 = (5600 + BC) / 5600

(11700 / 5200) x 5600 = 5600 + BC

117/52 x 5600 = 5600 + BC

BC = 12600 - 5600

BC = 7000

Now,

The plane’s distance from point A when it reaches point C.

= AB + BC

= 5600 + 7000

= 12600 feet

Thus,

The plane’s distance from point A when it reaches point C is 12600 feet.

Answer:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \frac{ 1 }{ 2\sqrt{x } } [/tex]

Step-by-step explanation:

we want to differentiate the following by using limit:

[tex] \displaystyle \frac{d}{dx} \sqrt{x} [/tex]

derivative definition by limit given by

[tex] \rm \displaystyle \frac{d}{dx} = \lim _{\Delta x \to 0} \left( \frac{f(x + \Delta x) - f(x)}{ \Delta x} \right) [/tex]

given that,

f(x)=√x

so,

f(x+∆x)=√(x+∆x)

thus substitute:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{\Delta x \to 0} \left( \frac{ \sqrt{x + \Delta x}- \sqrt{x} }{ \Delta x} \right) [/tex]

multiply both the numerator and denominator by the conjugate of the numerator:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{\Delta x \to 0} \left( \frac{ \sqrt{x + \Delta x}- \sqrt{x} }{ \Delta x} \times \frac{ \sqrt{x + \Delta x} + \sqrt{x} }{\sqrt{x + \Delta x} + \sqrt{x}} \right) [/tex]

simplify which yields:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{\Delta x \to 0} \left( \frac{ (\sqrt{x + \Delta x}) ^{2} - x }{ \Delta x(\sqrt{x + \Delta x} + \sqrt{x})} \right) [/tex]

simplify square:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{ \Delta x \to 0} \left( \frac{ x + \Delta x - x }{ \Delta x(\sqrt{x + \Delta x} + \sqrt{x})} \right) [/tex]

collect like terms:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{\Delta x \to 0} \left( \frac{ \Delta x }{ \Delta x(\sqrt{x + \Delta x} + \sqrt{x})} \right) [/tex]

reduce fraction:

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \lim _{\Delta x \to 0} \left( \frac{ 1 }{ (\sqrt{x + \Delta x} + \sqrt{x})} \right) [/tex]

get rid of ∆x as we are approaching its to 0

[tex] \rm \displaystyle \frac{d }{dx} \sqrt{x} = \frac{ 1 }{ \sqrt{x } + \sqrt{x}} [/tex]

simplify addition:
