Answer:

405

Step-by-step explanation:

Don't be confused about setting up the proportion. White has to go with white which is 4 and brown goes with 5.

The total is 9.

so proportion will look like this.

4/9 = 180/x          Cross Multiply

Before I solve this, notice that the white data is on top of the fraction, and the total is on the bottom of the fraction on either side of the proportion.

4x = 180 * 9

4x = 1620

x = 1620 / 4

x = 4 0 5

Notice that the brown is going to be bigger than the white but not by much

White                            180

Brown       405 - 180 = 225

Total                              405

Answer:

She spent $5.05 for her total purchase.

Step-by-step explanation:

First, you should convert the fractions into decimals to make it easier, which would make it, 1.5, .25, 1.

Second, multiply 1.5 by 2 because there are 1.5 pounds which are payed for $2.00. Do the others fractions corresponding with the number of pounds and the cost this same way. 1.5 multiplied by 2 is 3. .25 multiplied by 1.60 is 0.4, 1 multiplied by 1.65 is 1.65.

Lastly, Add it all up, 3+0.4+1.65=5.05

Answer:

Step-by-step explanation:

The vertex has a rotation (3,-2) --> (2,3).

or in x and y coordinates, (x,y) --> (-y,x).

the rotation that has this said rule is  r0, 90°. and  90° is equal to –270°.

the answers are:

r0, 90°

r0, –270°.

The transformations could have taken place are 270°or -90°.

A point, line, or geometric figure can be transformed in one of four ways, each of which affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.

We have,

Before rotation V(3, -2)

and, After rotation V'(2, 3)

Then, the possible transformations from V to V' are:

90 degrees counterclockwise rotation

270 degrees clockwise rotation

If the there is 90 degrees counterclockwise rotation (R0, -90) is given as:

(x, y) - > (-y, x)

Then we have (3, -2) -> (2, 3)

and, if 270 degrees clockwise rotation

(x, y) - > (-y, x)

Then we have (3, -2) -> (2, 3)

Thus, the transformation are 270°or -90°.

Answer:

[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]

Step-by-step explanation:

Represent white paint with w and black with b

Given

When w = 3; b = 1

Required

Determine the two equations

To get a gray paint, the w and b are needed in the following proportion:

[tex]3 * w = 1 * b[/tex] -----(1)

Solve for b

[tex]3 * w = b[/tex]

Reorder

[tex]b = 3 * w[/tex]

[tex]b = 3w[/tex] ---- This is an equation

To get another equation,

Recall that

[tex]3 * w = 1 * b[/tex]

Solve for w

[tex]3*w = b[/tex]

[tex]3w = b[/tex]

Make w the subject

[tex]w = \frac{1}{3}b[/tex]

Hence, the equations that show the relationship between w and b are:

[tex]w = \frac{1}{3}b[/tex] and [tex]b = 3w[/tex]

x= -1, y= 6

Step-by-step explanation:

9x + 7y =33---a

-6x = y---b

Put b into a,

9x + 7(-6x) = 33

9x - 42x = 33

-33x = 33

x = -1----c

put c into b,

-6(-1) = y

y=6

Answer:

The answer is (-1, -6)

Step-by-step explanation:

To get y by itself, you switch sides of the Y and the -6x

9x+7y=33

y= -6x

You then put the -6x where the y is

9x+ 7(-6x) = 33

9x -42x =33         9 -42 = -33

-33x = 33

It's now a one-step equation

x= -1

Now you put  the x value (-1) where the x is in y= 6x

y= 6 (-1)    y=-6

Answer:

g(3) = 6*2 = 12

Step-by-step explanation:

In this problem you're given more information than is necessary to solve it.  

g(x) = f(x)*h(x) is the product of functions f and h.

If x has the value 3, then:

f(x) = f(3) = 6, h(x) = h(3) = 2.  Thus, when x = 3 we have g(x) = g(3) = 6*2 = 12

The value of g(3) using g(x) = f(x)·h(x) is 12.

Given that, g(x) = f(x)·h(x).

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Put x=3 in g(x) = f(x)·h(x), we get

g(3) = f(3)·h(3)

⇒ g(3) =6×2

= 12

Therefore, the value of g(3) using g(x) = f(x)·h(x) is 12.

Answer:

The first riddle is Age. Some people love their age, some people hate their age. Age can change appearances and thoughts because as you mature you view things differently. If you take care of yourself, you will become die older than most people. Some people are fooled by age, they think someone is older or younger than they really are. Some people don't know someone's age, so it is a mystery. Some people try and hide their age. Age never decreases.

The second riddle is a shadow. A shadow is only one color, but it can be any shape or size. Shadows are stuck at the bottom, but it easily moves. Shadows appear in the sun, but not when it is raining because of the clouds. Shadows do no harm, and they can't feel anything.

Answer:

40.9 ft

Step-by-step explanation:

Perimeter is the sum of lengths of all outer sides of the shape. Since the rectangle has two pairs of parallel lines of the same length... It is safe to assume that the unmarked side length is 10 ft (just like it's parallel counterpart)

Now it is a simple matter of adding all of the outer sides.

8ft + 10 ft + 10 ft + 8.9 ft + 4 ft = 40.9 ft

Answer:

0.83

First, we convert the fraction to a decimal number by dividing the numerator by the denominator:

5 / 6 = 0.833

There are two parts to the decimal number above:

Integer Part: 0

Fractional Part: 833

Now, we will make the Fractional Part just two digits (nearest hundredth) by using our rounding rules.*

In this case, Rule I applies, so 5/6 (or 0.833) rounded to the nearest hundredth in decimal format is:
