b= -1.5

4/9=2/3 +1/3b

4/9= 6/9+1/3b

-2/9=1/3b

-2/9=3/9b

/-2/9

b= - 1.5

Answer:

Exact Form:

b = -2/3

Decimal Form:

b = -0.¯6

Answer:

The slope of line A is 2, because it goes up 2 units and over to the right 1, but you don't write the 1 in this case.

The slope of line B is -1/2, because it goes down 1 unit and over to the right 2 units.

For the last box: The slopes have opposite reciprocals.

Sorry if it didn't though.

The angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.

The given parameters;

The normal force on the larger weight (3 lb) is calculate as;

[tex]F_n = Mgcos(\theta)[/tex]

The net force on the larger weight is calculated as;

[tex]Mgsin(\theta) - T = 0[/tex]

where;

T = mg

[tex]Mgsin(\theta) - mg = 0\\\\(1.36\times 9.8)sin\theta \ - \ (0.91 \times 9.8) = 0\\\\13.328 sin(\theta) = 8.918\\\\sin(\theta) = \frac{8.918}{13.328} \\\\sin(\theta) = 0.669\\\\\theta = sin^{-1} (0.669)\\\\\theta = 42\ ^0[/tex]

Thus, the angle measure for the inclined ramp needed to keep the larger weight from sliding down the ramp is 42⁰.

Answer:

Step-by-step explanation:

to find this all you need to do is find the cos per full uniform by adding 1.25m for the blouse and 1.35m for the skirt. This will equal 2.6m per full uniform. you need to then multiply this by 12 to find the total fabric needed for the 12 uniforms which will equal 31.2. you then multiply this answer by the 50 cents per meter to get the cost which will be $15.60

Answer:

A Rational Number can be made by dividing an integer by an integer. (An integer itself has no fractional part.)

Answer:

Make a line using points (0,0) (1,6) and (-1,-6)

Step-by-step explanation:

Okay, so your first point will be (0,0) at the origin because in your equation there is no y-intercept.

For your next point, we have to use Rise/Run, or slope, to find our next point. In y=mx+b, m is the slope. So for y=6x, 6/1 is our slope.

So from the origin, we go up 6 and to the right once. This will give us the point (1,6)

Incase you need another point, we can also go down 6 and left 1. This gives us the point (-1,-6)

Answer:

they are 2 and 9

Step-by-step explanation:

Set up equation for two numbers a and b:

[tex]3a-b=-3[/tex] and [tex]a+b=11[/tex]

solve the system of equations:

add two equations together we get:

[tex]3a-b+a+b=-3+11[/tex]

[tex]4a=8[/tex]

[tex]a=2[/tex]

Since, a+b=11

thus  [tex]b = 9[/tex]

Answer:

2/5 are gold

Step-by-step explanation:

24 would be gold, and 24/60 can simplify to 4/10, and can them simplify again to 2/5.

:))

Answer:

[tex]\frac{2}{5}[/tex] of the stars are gold.

Step-by-step explanation:

No. of gold stars

= (60÷10)×4

= 6×4

= 24

Hence, fraction of stars that are gold = [tex]\frac{24}{60}[/tex] = [tex]\frac{2}{5}[/tex]

Answer:

The vertex is (-3,0)

Step-by-step explanation:

Insert the values into the given equation on the assignment in order to get the coordinates of the vertex.

The values are:

a = 1

b = 6

c = 9

For the x coordinate, insert the a and b values into the equation (-b/2a):

-6/(2*1) =

-6/(2) =

-3

So now we know the x value is 3, to find the y value insert the a, b, and c values into the equation -(b^2-4ac)/4a

-(6^2 - (4*1*9))/(4*1) =

-(36-(36))/4 =

-0/4 =

0

So the y value is 0 and the vertex is (x,y), so the vertex is (-3,0)

Answer:

unit price = 4$ a pound

Step-by-step explanation:

3 pounds for a total of 12$, but you need to know the price of 1 individul unit, so within those 3 lbs is 3 "individul units" (aka 1 pound)

total cost = 12$ for all 3 units so divide 12 by 3 (12/3) = 4  --> Giving you the cost of 1 unit  which is $4.00

Check you work : 3 units (3lbs) , you know 1 unit(pound) costs 4$ and your total you paid needs to be equal to 12$

SO: 3 (your pounds) x 4 (price PER unit) = 12  

12 = 12  

Youre done!

Answer:

? = 3x

Step-by-step explanation:

2(? + 5) = 6x + 10

You must plug in a number that will get the same value on both sides of the equal sign.

2*5 = 10

2*? = 6x

6x/2 = 3x

Answer:

1. 452.16 square centimeters

2. 150.72 square centimeters

3. 25.12 centimeters

Step-by-step explanation:

1. the area of the circle

The area of a circle can be calculated with:

[tex]a=\pi r^2[/tex]

The area of the given circle then, is:

[tex]a=\pi 12^2\\a=144\pi\\[/tex]

or just 452.16 square centimeters.

2. the area of the minor sector

There's a convenient formula for this, but I don't remember it and you don't really need it. A full circle is 360°, and 120° is exactly 1 third of that. 1 third of the size means 1 third of the area:

[tex]a=452.16*\frac{1}{3} \\a=150.72[/tex]

or 150.72 square centimeters

3. the area of the minor arc

You can do the same thing here. The circumference of a circle is:

[tex]u=2\pi r[/tex]

So the circumference of the given circle is:

[tex]u=2\pi (12)\\u=24\pi[/tex]

or about 75.36 centimeters.

One third of that:

[tex]u=75.36*\frac{1}{3} \\u=25.12[/tex]

25.12 centimeters.

Answer: 1.5 gallons

Step-by-step explanation:

(1/2) of a 2oz tube covers 0.25ft^2.  Make this into a conversion factor:

1 oz/0.25ft^2

4oz/ft^2

They have a 48 ft^2 mural.  Assuming no mistakes in painting, they will need:

(48 ft^2)*(1 oz/0.25ft^2) = 192 oz  [Note how the ft^2 units cancel]

There are 128oz/gallon.  Make this a conversion factor:

(gallon/128oz)

Convert 192 oz to gallons:  (192 oz)*(gallon/128oz) = 1.5 gallons

Answer:

484

Step-by-step explanation:

This is because 22 squared is 484.

When you take something out from under the square root symbol, you have to square it.

Thus, a number outside the square root to the left of the symbol was originally that same number squared under the square root symbol.

Thus as 22 is outside the symbol, it was originally 22 squared while under the symbol, and 22 squared is 484.
