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
Yosemite Falls is the highest waterfall in North America and the fifth highest in the world. When viewed from the valley, it appears to be a single waterfall. However, it actually has three parts. The upper fall has the longest drop of 1430 feet. The middle cascade is 675 feet long, and the lower fall drops another 320 feet. What is the total length that the water falls?
Answer:
The water falls a total length of 2,425 feet
Step-by-step explanation:
In order to calculate the total length of the waterfall, we will find the sum of the three parts of the waterfall.
Length of upper fall = 1430 feet
Length of middle cascade = 675 feet
Length of lowe fall = 320 feet
Total length of fall = (Length of upper fall) + (Length of middle cascade) + (Length of lowe fall)
= 1430 + 675 + 320 = 2,425 feet
Total length that the water falls = 2,425 feet

Select the slope of the line
Answer:
Undefined.
Step-by-step explanation:
The line given on the graph is vertical.
All vertical lines have an undefined slope.
This is because that it has no horizontal (run) change.
If you used the slope formula for the points, the denominator of the fraction will be a zero, and and you cannot divide by zero.
Hope this helps!
Brainilest is appreciated.
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°.

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]

hey i got riddles for people
I am something people love or hate. I change peoples appearances and thoughts. If a person takes care of them self I will go up even higher. To some people I will fool them. To others I am a mystery. Some people might want to try and hide me but I will show. No matter how hard people try I will Never go down. What am I?
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.

Name an object that could be about the same length as each measurement. A. 4 inches b. 6 feet c. 1 meter d. 5 yards a. 6 centimeters b. 2 millimeters c. 3 kilometers
Answer and Step-by-step explanation:
A. 4 inches: An object that's 4 inches is about 2.54 centimeters or 25.4 millimeters. An business envelope is typically about 4 inches by 9 inches for example.
B. 6 feet: A 6 feet object is quite big when compared to just 4 inches. A feet is 12 inches hence 6 feet is 72 inches. A very tall human being is typically 6 feet.
C. 1 meter: A meter is about 39.37 inches hence it is quite big when compared to a feet. A baseball bat is one meter long.
D. 5 yards: A yard is 36 inches hence a bit smaller than a meter. A trampoline could be 5 yards for example
E. 6 centimeters: one centimeter is 0.394 inches hence smaller than an inch. A 6 centimeters object for example is pencil for writing.
F. 2 millimeters: a millimeter is 0.0394 inches hence smaller than a centimeter and an inch. An orange seed could be 2 millimeters long
G. 3 kilometers: one kilometer is 39370.079 inches hence a kilometer is bigger than inches, meter, feet, yards, centimeters, millimeters. A very big tree could be 3 kilometers long

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:
0.83

constant speed; 17.5 mi/h
O constant speed; 70 mi/h
constant speed; 35 mi/h
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.
