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

Write the equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 and graph
Answer:
The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is: y=-x+3
Step-by-step explanation:
Given equation of line is:
[tex]y = x+2[/tex]
Comparing it with the general form of equation of line in slope-intercept form
[tex]y = mx+b[/tex]
The slope of given line is 1 as the co-efficient of x in the equation is 1.
When two lines are perpendicular, the product of their slopes is -1
Let m1 be the slope of new line
Then
[tex]m.m_1 = -1\\1.m_1 = -1\\m_1 = -1[/tex]
The equation of new line perpendicular to given line will be:
[tex]y = m_1x+b[/tex]
Putting the value of m1
[tex]y = -x+b[/tex]
To find the value of b, the given point will be put into the equation
So,
[tex]-1 = -(4)+b\\-1 = -4+b\\-1+4 = b\\b = 3[/tex]
The final equation of line is: y = -x+3
Hence,
The equation in slope-intercept form through the point (4, -1) and is perpendicular to the line y = x + 2 is:
[tex]y = -x+3[/tex]
Graph:(Attached)
The graph is made using the online graphing tool "Desmos". The red line in the graph represents the line y = x+2 and the blue line represents the line (y=-x+3) perpendicular to given line
Which ordered pair makes both inequalities true?
y > –2x + 3
y < x – 2
On a coordinate plane, 2 straight lines are shown. The first solid line has a positive slope and goes through (0, negative 2) and (2, 0). Everything to the right of the line is shaded. The second dashed line has a negative slope and goes through (0, 3) and (1, 1). Everything to the right of the line is shaded.
(0,0)
(0,–1)
(1,1)
(3,0)
Answer:
its D. (3,0)
Step-by-step explanation:
The ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that:
The inequalities are:
y > –2x + 3
y < x – 2
Plug the point in the above inequality:
(3,0)
The above point satisfy the inequality.
Thus, the ordered pair makes both inequalities true is (3,0) if the inequalities are y > –2x + 3, and y < x – 2.

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]

Jason downloaded 288 pictures from his camera. Of the pictures, 38% are of his family. About how many pictures are of his family? Use a rate per 100 to estimate.
Answer:
We can rewrite this problem as:What is 38% of 288?
"Percent" or "%" means "out of 100" or "per 100", Therefore 38% can be written as
38 /100
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of pictures we are looking for "p".
Putting this altogether we can write this equation and solve for p while keeping the equation balanced:
p = 38 /100 × 288
p = 10944 /100
p = 109

What is the equation of the circle with center (-3,1) that passes through the point (-5, 3)?
A)
(x - 3)2 + (y + 1)2 = 8
B)
(x + 3)2 + (y – 1)2 = 8
0)
(x + 1)2 – (y - 3)2 = 8
D)
(x + 3)2 - () - 1)2 = 8
Answer:
Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.
Step-by-step explanation:
The equation of a circle with center (h,k) and radius r is given by:
[tex](x-h)^2 + (y-k)^2 = r^2[/tex]
Given
Center = (h,k) = (-3,1)
=> h = -3
=> k = 1
The distance between the center of circle and the point through which the circle passes will be the radius.
The distance formula is given by:
[tex]r = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
Given
[tex](x_1,y_1) = (-3,1)\\(x_2,y_2) = (-5,3)[/tex]
Putting the values in the formula
[tex]r = \sqrt{(-5+3)^2+(3-1)^2}\\r = \sqrt{(-2)^2+(2)^2}\\r = \sqrt{4+4}\\r = \sqrt{8}[/tex]
Putting the values of h,k and r in general form of equation
[tex]\{x-(-3)}^2\} +(y-1)^2 = (\sqrt{8})^2\\(x+3)^2+(y-1)^2 = 8[/tex]
Hence,
Option B) (x + 3)^2 + (y – 1)^2 = 8 is the correct answer.

Juan made $253 for 11 hours of work. At the same rate, how many hours would he have to work to make $391?
Answer:
17 hours
Step-by-step explanation:
givens:
-he made $253 for 11 hours of work
-how many hours of work for $391
set a proportion
253 391
----- = ----
11 h h=hours
cross multiply
253h=391 times 11
253h=4301
divide 253 in both sides
4301/253
17 hours!
