=Mr.Lehmans hourly rate for labor is 20$

=30+40=70-50=20

Answer:

The Answer is 15$

You'd need to get the slope

it tells us how he charges with respect to Time

So picking any Point on the graph. Let's say (0,10) and (2,40)

m(slope) = y2-y1/x2-x1

= 40-10/2-0

=30/2

= 15$

Picking other points would still give this value

Answer:

126.5 cm2

Step-by-step explanation:

First, the equation to find the area of a trapezoid is A= 1/2(b1 + b2)h  , where b1 is the first length and b2 is the second length and h is the height. For these measurements, you would simply factor them into the equation-  A= 1/2(8 + 15)11. Then using pemdas, 8+15= 23... multiplied by 1/2 equalling 11.5. Then multiply 11.5 by 11 to get your answer of 126.5 then add the units.

Answer:

y=4/5x-3 - (-5, -7)

Step-by-step explanation:

So to solve this, lets just plug in each value for x, and see if the y value we get is equal to one of our answers.

So we have (-10, 5)

Well plug in -10 for 4/5x we get:

-40/5=-8

Next we take that value and solve:

y=-8-3

y=-11

The answer for this was 5, not -11.

Ill skip a few steps:

(10, -11):

Plug in 10 we get:

y=8-3 which is y=5. This is not right, for it needed to be -11.

Next we have (5, -1)

This gets us y=4-3 this is y=1 which is not -1. So thats not right.

Finally we have (-5, -7):

This gets us y=-4-3 this is y=-7. What was our y value? -7!

So the answer is (-5, -7)

I hope this helps! :)

Step-by-step explanation:

(25-10) ÷ 5 × 8

15 ÷ 5 × 8

3 × 8

24

Answer:

24

Step-by-step explanation:

Any work inside parentheses must be done first:  (5^2 - 10).  Also:

Exponentiation is done before addition/subtraction:  5^2 - 10 = 25 - 10 = 15

 So now we have 15 / 5 * 2^3 and recognize exponentiation again:

                               15 / 5 * 8

Then, since multiplication and division have the same order of priority,

carry out the division in 15/5 and then multiply the result (3) by 8

to obtain 24 (final answer)

198.5 is the answer

50X4-(3÷2)=198.5

Answer: 198.5

Step-by-step explanation:

= 50x4-(3 divided by 2)

= 50x4-(3/2)

= (50 x 4) - ( 3/2 )

= (200) - (3/2)

= 200 - 1.5

Answer:

80 teaspoons

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Teaspoon capacity = 0.015 L

Total quantity = 1.2L

So, we can calculate the number of teaspoons in 1.2L oil by using following formula,

Number of teaspoons = Total quantity ÷ Teaspoon capacity

By putting the value of following, we get

Number of teaspoons = 1.2 ÷ 0.015

= 80 teaspoons

Hence, there are 80 teaspoons of oil in 1.2L.

The radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

A circle's or sphere's radius is any line segment that connects the object's centre to its perimeter in classical geometry; in more contemporary usage, it is also the length of those line segments.

The word "radius" is derived from the Latin word "radius," which also refers to the spoke of a chariot wheel. Use the equation  [tex]r =\frac{D}{2}[/tex]  to determine the radius, which is equal to half the diameter. This is the same process used to determine a circle's radius from its diameter.

A hemisphere's volume is equal to  [tex]\frac{2}{3} \pi r^3[/tex]  cubic units. Where is an estimated constant with a value of [tex]3.14[/tex]. The hemisphere's radius is denoted by "r."

Required calculations are:

V = r

r = radius.

Given, V = 38153 in³

[tex]38153 = \frac{2}{3} \pi r^3[/tex]

[tex]r^3 = \frac{3 \times 38153}{2 \times \pi }[/tex]

[tex]r = 3\sqrt{\frac{3 \times 38153}{2 \times \pi }}[/tex]

r =26.3 in

Therefore, the radius of a hemisphere with a volume of [tex]38153[/tex] in", to the nearest tenth of an inch is [tex]26.3[/tex].

Answer:

a. Volume 120km^2

Surface area 168km^2

Step-by-step explanation:

When the root of x²-bx+c = 0 is decreased by 2, the resulting equation is x²-2x+1, then b = 2 and c = 1

The values of variables satisfying the given quadratic equation are called its roots.

if the roots of a quadratic equation ax²+bx+c = 0 are alpha and beta

alpha + beta = -b/a and

alpha × beta = c/a

when the roots are reduced by 2

alpha-2+ beta-2 = -b/a

(alpha+beta)-4 = -b/a

alpha+ Bata = -b/a + 4

the resulting equation is x²-2x+1 = 0

a = 1, b = -2 and c = 1

therefore alpha +beta = -b/a = -(-2)/1 = 2

therefore 2 = -b/a+4

a = 1

2 = -b+4

b = 4-2 = 2

alpha×beta = c/a = 1/1

(alpha -2)× ( beta -2) = (alpha)( beta) -2(alpha+beta) + 4 = 1-2(2)+4 = 1

therefore b = 2 , c = 1

Answer:

2/3

Step-by-step explanation:

Slope = rise / run = 2 / 3

Because points A, B, C, and D are collinear (meaning on the same line), the slope for line segment AB is the same as the slope for segment DC.

Answer:

2/3.

Step-by-step explanation:

The 2 triangles are similar so their corresponding sides are in same ratio.

The sides BA and CD are collinear so theire slopes are the same.

Slope of BA = rise/run = 2/3 so slope of DC is also 2/3.

Explanation:

A full circle of radius 5 inches would have a perimeter or circumference of...

C = 2*pi*r

C = 2*3.14*5

C = 31.4

This value is approximate because pi = 3.14 is approximate.

The distance around a full circle with radius 5 inches is roughly 31.4 inches, but we only want a quarter of this. Therefore, the distance around the curved portion of the quarter circle is roughly C/4 = (31.4)/4 = 7.85 inches.

Choice A would be the answer if your teacher only cared about the curved portion. However, don't forget about the straight line portions that also make up the quarter circle. Choice A might have been put there as a trick answer.

We'll add on the two copies of the radius 5 inches to get a total perimeter of 5+5+7.85 = 10+7.85 = 17.85 = 17.9 inches, which points to choice C as the answer.

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

Side note:

If we used a more accurate version of pi, say the version stored in your calculator, then the perimeter is roughly

5+5+(2*pi*5)/4 = 17.8539816339744

Rounding to the nearest tenth leads to the same answer of 17.9 inches

$46,320

Step-by-step explanation:

Given that

The rate of interest is 6.1%

The amount is $71,000

And, the time period is  7 years

We need to find out the invested amount

As we know that

In the compounded continously, the following formula should be used

Amount = Invested amount × e^(rate × time period)

$71,000 =  Invested amount × e^(6.1% × 7)

$71,000 =  Invested amount × e^0.427

$71,000 =  Invested amount × 1.5326

So, the investment amount is

= $71,000 ÷ 1.5326

= $46324,912
