Margie bought 1 1/2
pounds of tomatoes for $2.00 per pound,
1/4 pound of onions for $1.60 per pound, and 1 pound of apples for $1.65 per pound. How much did she pay for her total purchase?
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

9x + 7y = 33
-6x = y
Answer:
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
Solve for y: -5y + 6 = 16

Pablo mixes 3 units white paint and 1 unit black paint to make gray paint. What two equations show the relationship between units of white paint, w, and units of black paint, b? Show your work.
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]
What is the perimeter of this shape
Answer:
40.9
Step-by-step explanation:
8+10+8.9+10+4=40.9
hope this helps :3
if it did pls mark brainliest
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

If two line segments have the same length, which of the
following must be true?
A. They form a right angle.
B. They are congruent.
ht
C. They are equal.
O D. They share an endpoint.
Suppose that
g(x) = f(x)•h(x),
f(3) = 6,
h(3) = 2,
h'(6)=4,
h'(3)=15 and
f'(3) = 8.
Find g(3).
(A) 32
(C) 106
(B) 8
(D) 60
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).
What is the function?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.

variable speed; 70 mi/h
Answer: it’s 35 mi/h
Step-by-step explanation:
The constant speed is 35 miles per hour. Therefore, option C is the correct answer.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
The slope of rate of change of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
From the graph,
Constant speed = 35 miles/1 hour
= 35 miles per hour
Therefore, option C is the correct answer.

The ratio of brown tiles to white tiles in Mrs.Harris kitchen in 4 to 5. There are 180 white tiles in the kitchen. What is the total number of tiles in mrs. Harris kitchen
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

what is 5/6 rounded to the nearest hundredth?
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:

Write an expression that is equivalent to 1/2a - 4
The expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)
Given the expression 1/2a - 8, to get the equivalent expression, we will factor out 1/2 from the expression to have:
1/2 (a - 8 (2))Note that we will need to multiply the second term by the denominator of the fraction to neutralize the fraction.
Simplify to have:
1/2 (x - 8 (2))1/2 (x - 16)Hence the expression that is equivalent to 1/2a - 4 is 1/2 (a - 16)

One vertex of a polygon is located at (3, –2). After a rotation, the vertex is located at (2, 3).
Which transformations could have taken place? Select all options.
Group of answer choices
90°
180°
270°
-270°
-180°
–90°
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°.
What is Transformation?
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°.

Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?
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.
