Estimate 151% of 72.

Answer:

Step-by-step explanation:

all three angles must equal 180 bc theyre on a straight line

so add 76 + 63 to get 139

then subtract that from 180

180 - 139 = 41

so x = 41

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant

Step-by-step explanation:

Answer: This is a fraction equal to

48 kilometers ÷ 3 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 3

48 kilometers ÷ 3

3 hours ÷ 3

=  

16 kilometers

1 hour

=  

16 kilometers

[tex]y=2x-3[/tex]

Step-by-step explanation:

1. Using the point of intersections, we use the substitution method to find the coordinates of the line parallel to [tex]2x-y-9=0[/tex]

[tex]5x+y+4=0[/tex]

[tex]y= -4-5x[/tex]

substituting the value of y in [tex]2x+3y=1[/tex]:

[tex]2x +3(-4-5x)=1\\\\2x-12-15x-1=0\\-13x=13x\\x= \frac{13}{-13}= -1[/tex]

substituting x=-1 in y= -4-5x:

[tex]y= 1[/tex] (upon solving, you should get this)

[tex](x,y)= (-1,1)[/tex]

2. Using y=mx+c and making y the subject of the formula 2x-y-9=0 and using the coordinate we found earlier, we will find the equation of the parallel line. (We make y the subject of the formula to find the gradient)

[tex]2x-y-9=0\\2x-9=y\\y= 2x-9[/tex]

[tex]y= mx+c\\[/tex]

-1= 2 x 1 +c

-3=c

11. Slope of the line is 7/10.

12. Slope of the line is [tex]-\frac{1}{3}[/tex]

Step-by-step explanation:

11. Given points are:

(-6, 1) and (4, 8)

Slope of a line is given by the formula;

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m = [tex]\frac{8-1}{4-(-6)}[/tex]

m = [tex]\frac{7}{4+6}[/tex]

m = [tex]\frac{7}{10}[/tex]

Slope of the line is 7/10.

12. Given points are:

(2, -3) and (5, -4)

Slope of the equation is;

m = [tex]\frac{-4-(-3)}{5-2}[/tex]

m = [tex]\frac{-4+3}{3}[/tex]

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

Hence,

Slope of the line is [tex]-\frac{1}{3}[/tex].

Answer:

Step-by-step explanation:

60x500/3=10,000

To earn $10,000 in one day Mark needs 60 clients in one day.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given that, Mark makes a total of $500 for every 3 clients she acquired.

∴ To find how many clients he needs to earn $10,000 in a day we have to divide the earnings wanted by earnings per client which is,

= (10000)÷(500/3).

= 10000×3/500.

= 100×3/5.

= 300/5.

= 60.

[tex]y+2=-3(x-2)[/tex]

Step-by-step explanation:

The point-slope form of the straight line is given as

[tex]y-y_1=m(x-x_1)[/tex]

Here [tex]m=-3[/tex] and [tex](x_1, y_1)=(2, -2)[/tex]

[tex]y+2=-3(x-2)[/tex]

So I answered one of your rounding questions before. I am going to give you some math rules so that you can do it on your own.

If you are rounding to the hundreds place and the number in the tens place is 4 or less, the number in the hundreds place stays the same and the other places are 0.

If you are rounding to the hundreds place and the number in the tens place is 5 or more, the number in the hundreds place increases by 1 and the other places are 0.

The answer to your question is 400.

Answer:

Step-by-step explanation:

1. The slope of the given line is the x-coefficient, 7. The slope of the perpendicular line is the negative reciprocal of this: -1/7. Since the line goes through the origin, the y-intercept is zero.

  y = -1/7x

__

2. The first part of this problem is to find the solution to the given system of equations. We can substitute for x to do that:

  3(5 -y)-2y = 10

  15 -5y = 10 . . . simplify

  -3 +y = -2 . . . . divide by -2

  y = 1, x = 4 . . . add 3 to find y; subtract y from 5 to find x

__

The second part of this problem requires we note the slope of the parallel line. It is the x-coefficient, 2. The y-intercept can be found from ...

  b = y -mx = 1 -2(4) = -7

So, the desired line in y=mx+b form is ...

  y = 2x -7

Answer:

The answer is 84.

Step-by-step explanation:

The given equation is

4x*2 + 2x -5 = 0

Here a= 4, b= 2, c= -5

Since Discriminant= b*2 -4ac

Putting values

Discriminant= (2)*2 - 4(4)(-5)

= 4 + 80

= 84

Since our Discriminant(84) is >0 and is not a perfect square so the roots of the given equation are unequal and irrational(real).

Answer:

The following system of equation has no solution.

Step-by-step explanation:

since both of them are equal to y, set them equal to each other:

3x+1=3x+7

if you subtract both sides by 3x, you get 1=7. That is a contradiction, so this has no solutions.

This equation has no solution.

An inconsistent system is a system that has no solution in any case scenario.

Given this system of equations y=3x+1,  y=3x+7.

on comparing both equations multiples of x and y are equal therefore, there will be no solution for a given equation.

Answer:

Step-by-step explanation:

Volume= L*H*W

1*1*1= 1

So the volume is 1

I hope this helps!!!

The volume of cube is 1 feet³.

Volume = a³, where a is the length of the cube's sides or edges, is the formula for the cube's volume.

The basic formula for volume is length x  breadth x height, as opposed to length, width, and height for the area of a rectangular shape.

Given:

Edge length of cube= 1 feet.

So, Volume of cube = l³

                                  = (1)³

                                  = 1 x 1 x 1

                                  = 1 ft³

Hence, the volume is 1 feet³.

Answer:

$0.86

Step-by-step explanation:

Let's say the cost of the apples is A and the cost of the pears is P.

3A+6P=7.44

4A+10P=11.58

Now our best bet is elimination. We have to multiply the equations (Dont' forget about both sides, otherwise it does not work!) by the least common multiple.

We want to keep the variable A, meaning we'll have to target B. The least common multiple is 30, so now we'll multiply both equations like so:

15A+30P=37.20

12A+30P=34.74

Now we subtract the second equation from the first one. We get:

3A=2.46

And we divide both sides by 3, leaving us with

A=$0.86 or 86 cents.
