Answers

Answer 1

Answer:

Step-by-step explanation:

15)  point D=(3,1)

for AB we can see that there is an exact triangle of 2 and 5

so AD =  [tex]\sqrt{2^{2} +5^{2} }[/tex] = [tex]\sqrt{29}[/tex]  and 2(AD) = AB

AB = 2*[tex]\sqrt{29}[/tex]  ( this is an exact answer, leave it with the square root)

16) find CD  length  we know the points at each end so use the distance formula  P1=(-3,4)  P2=(3,1)

Dist. = [tex]\sqrt{(3-(-3))^{2} +(1-4)^{2} }[/tex]

Dist. =[tex]\sqrt{45}[/tex]   = [tex]\sqrt{9*5}[/tex]  = 3[tex]\sqrt{5}[/tex] ( exact answer leave the square root )

CD = 3[tex]\sqrt{5}[/tex]

17)  1/3 of the way along CD from D towards C is where the centroid is.. I just happen to know that from doing this too often.  :/

so that mean  [tex]\frac{1}{3}[/tex] * [tex]3\sqrt{5}[/tex]   is the distance from D to the centroid or [tex]\sqrt{5}[/tex]

also b/c I happen to know.. :/    c = [tex]\sqrt{1^{2}+ 2^{2} }[/tex] = [tex]\sqrt{5}[/tex]  off the top of my head I can see that the point (1,2) is our centroid for this object.. they made it really easy  ... okay..  relatively easy. .:D  

Centroid = (1,2)

PLZ I NEED HELP AND I DON"T KNOW THE ANSWER!!

Answers

Answer:

Step-by-step explanation:

$ 3750 = truck rental; $125 per ton of sugar transported

C is cost; S is number of tons transported

Equation relating C to S would be a linear equation like y = mx + b

C = 125S + $3750

This equation would be graphed in the first quadrant only

you would start with your y-intercept at (0, 3750)

As x increases by 1, your y increases by 125 yielding these points:

(1, 3875) (2, 4000) (3, 4125) etc.

This shows that for each increase by one ton of sugar, the cost goes up $125

1)Cost of 1 ton = $ 2000

Cost of 2 ton = $3500

Cost of 3 ton = $5000

$ 1500 increase for each of ton of sugar being transported.

2) (1 , 2000) ; (2 , 3500)

Slope =

= 1500

Which list of fractions is in order from smallest to largest? 1/6,1/3 ,1/2 ,1/2 ,1/3 ,1/6 ,1/6 ,1/2 ,1/3, 1/2, 1/6, 1/3

Answers

Answer:

The smallest order of fractions in that order would be,

Step-by-step explanation:

1/6, 1/3, 1/2

because the bigger the denominater, the larger the whole is, and in 1/2, it would be equivalent to half, but 1/6 would be smaller. Let's say if it were 3/6, it would be equivalent to 1/2 because its half right? so thats another way you can tell how one fraction is smaller than another.

1/6,1/3,1/2 is the  list of fractions is in order from smallest to largest.

What is Fraction?

A fraction represents a part of a whole.

The given three fractions are 1/6, 1/3 and 1/2.

We need to order them smallest to largest.

Let us make the denominator same for all the three fractions to compare which is larger and smaller.

1/6×2/2=2/12

1/3×4/4=4/12

1/2×6/6=6/12

So 1/6 is smaller, 1/2 is bigger.

We know Arranging numbers in increasing order, that is, from smallest to largest is known as ascending order.

by using ascending order we can order the fractions like 1/6,1/3,1/2.

Hence, 1/6,1/3,1/2 is the  list of fractions is in order from smallest to largest.

Answer:

blue point value is -10

Step-by-step explanation:

First lets find the difference between each point on the line,

The gap between 10 and 2 has 2 points

So 10 - 2 = 8 is the difference in value between point A(10) and point C(2), but we need to find difference between each point,

So 8/2 = 4 is the difference between each point from top to bottom.

There is 3 points after 2 to reach blue,

So 4 x 3 = 12, is the difference in value between point C(2) and point blue,

So, subtracting 12 from 2 will get us the value of blue, 2 - 12 = -10

Therefore the value of blue point is -10

The formula for the area of a trapezold with altitude k and bases m and n is A=k/2(m+n)
Solve for m.

Answers

Answer:

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.

Step-by-step explanation:

Given the expression

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Solving for 'm'

[tex]A=\frac{k}{2}\left(m+n\right)[/tex]

Flip the equation

[tex]\frac{k}{2}\left(m+n\right)=A[/tex]

Expanding by applying the distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\frac{1}{2}km+\frac{1}{2}kn=A[/tex]

Add (-1)/2 × kn to both sides

[tex]\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A[/tex]

simplify

[tex]\frac{1}{2}km=-\frac{1}{2}kn+A[/tex]

Divide both sides by k/2

[tex]\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}[/tex]

[tex]m=\frac{2A-kn}{k}[/tex]

Therefore,

[tex]m=\frac{2A-kn}{k}[/tex]

Hence, option C is true.
