Answer:
The answer is 9/2
Step-by-step explanation:
3/4 = x/6
or, 4x = 18
or, x = 18/4
or, x = 9/2
x = 9/2
Janice wants to find the area of a square tabletop.She uses the formula for the area of a square: A=s2, where s is the length of one side of the square.If s= 3 feet what is the area of the tabltop
Answer:9
Step-by-step explanation:
You said that the areas is one side multiplied by 2. If one side (S) is 3, then 3 x 3 = 9.
Mr. Shaw graphs the function f(x) = -5x + 2 for his class. The line contains the point (-2, 12). What is the point-slope
form of the equation of the line he graphed?
Oy - 12 = -5(x + 2)
Oy - 12 = 2(x + 2)
O y + 12 = 2(x - 2)
O y + 12 = -5(x - 2)
Answer:
The first choice is correct. y-12=-5(x+2)
Step-by-step explanation:
Point-Slope Form of a Line
The point-slope form of the equation of a line is:
y-k=m(x-h)
Where m is the slope and (h,k) is a point through which the line passes.
The equation of the line in slope-intercept form is:
y=mx+b
Where b is the y-intercept.
Mr. Shaw graphs the function y=f(x)=-5x+2
The coefficient of the x can be identified as the slope m=-5. We are given the point (-2,12) to build the point-slope form of Mr. Shaw's line as follows:
y-12=-5(x+2)
The first choice is correct. y-12=-5(x+2)

translations: 1 unit left and 4 units up
F(2,-2), G(3,0), H(4,3)
Answer:
F(-1,2), G(2,4), H(3,7)
Step-by-step explanation:
When you move left to right, it changes the x in (x,y)
When you move up and down, it changes the y in (x,y)
So, if it moves 1 unit to the left, the x decreases by 1
And if it goes 4 units up, the y increases by 4
Are this two triangles similar?
Yes

======================================================
Explanation:
Focus on triangle ABC. Let's find the missing angle
A+B+C = 180
113+B+22 = 180
B+135 = 180
B = 180-135
B = 45
Between the triangles, have two pairs of angles that are congruent
A = D = 113
B = E = 45
Which is enough to prove the triangles are similar through the angle angle (AA) similarity theorem. This must mean that C = F = 22
Since we have A pair with D, and B pair with E, this means that [tex]\triangle ABC \sim \triangle DE F[/tex]
The order of the letters is important so we know how the angles pair up. The first letters pair up together, the second letters pair up, and so on.
Consequently, this means sides BC and EF pair up and AC and DF pair up
We can then say...
BC/EF = AC/DF
18/12 = x/4
18*4 = 12*x

Eleanor was looking to save money and make her home more energy efficient. She heard about LED
light bulbs but wanted to calculate the actual cost per year before buying them. Eleanor found that
incandescent bulbs cost $0.01 per hour in electricity, while LED's cost $0.0022 per hour. If the average
home has 65 light bulbs and has their lights on for 4 hours per day, what is the savings for 1 year for
Eleanor to switch all of her light bulbs to LED's?

A kennel owner has 400 feet of fencing to enclose a rectangular dog exercise pen. Express the area of the exercise pen, A, as a function of one of its dimensions, x. A(x) = x(x - 200) A(x) = x(x - 200) A(x) = x(400 - x) A(x) = x(400 - x) A(x) = x(200 - x) A(x) = x(200 - x) A(x) = (200 - x)2
Answer:
A(x) = x(200-x)
Step-by-step explanation:
400 feet of fencing to enclose a rectangular dog exercise pen means the perimeter of rectangle is 400 feet
If x is length and y is breadth. Perimeter is given by :
P = 2(x+y)
400 = 2(x+y)
⇒ (x+y) = 200 .....(1)
y = 200-x
Area of a rectangle is given by :
A = xy
A(x) = x(200-x)
Hence, the area as a function of length of rectangle is x(200-x).

The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by latex of the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?
Complete question :
The temperature at 5:00 a.m. was –6 °F. By 3:00 p.m., the temperature had risen to a high of 36 °F. If the temperature at 8:00 p.m. decreased from the high by the change in temperature in Fahrenheit degrees from 5:00 a.m. to 3:00 p.m., what was the temperature at 8:00 p.m.?
Answer:
-6°F
Step-by-step explanation:
Temperature at 5am (t1) = - 6°F
Temperature at 3pm (t2) = 36°F
Change in temperature, between 5am and 3pm:
(t2 - t1) = (36 - (-6)) = (36 + 6) = 42°F
Hence, temperature at 8:00 pm:
High temperature - change in temperature between (5am - 3pm)
36°F - 42°F = - 6°F

convert .932 into a fraction
Answer:
932/1000
Step-by-step explanation:
To write .932 as a fraction you have to write .932 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.932 = .932/1 = 9.32/10 = 93.2/100 = 932/1000
And finally we have:
.932 as a fraction equals 932/1000

The Montanez family is a family of four people. They have used 3,485.78 gallons of water so far this month. They cannot exceed 7,250.50 gallons per month during drought season. Write an inequality to show how much water just one member of the family can use for the remainder of the month, assuming each family member uses the same amount of water every month.
Answer: yes
Step-by-step explanation:
this month 3485.78/4 = 871.445 gallons per person
Drought month 7250.50/4 = 1812.625
difference 7250.50 - 3485.78 = 3764.72
slope (M)= rise/run=y/x=(y2-y1)/(x2-x1)

Which inequality is represented by this graph?
Answer: C
Step-by-step explanation:
The height, hh, of a plant (in inches) ww weeks since it was planted is represented by the equation h=1.2w+3h=1.2w+3. How many weeks ( round up to the nearest whole number) will it take the plant to reach one foot? ( Hint: convert feet to inches.) Answer value
Answer:
It will take 8 weeks for the plant to reach one foot.
Step-by-step explanation:
The equation is:
[tex] h = 1.2w + 3 [/tex]
Where:
h: is the height = 1 foot
w: is the time in weeks =?
We can convert feet to inches as follows:
[tex] 1 feet = 12 inches [/tex]
[tex] h = 1 ft*\frac{12 in}{1 ft} = 12 in [/tex]
Hence, the number of weeks is:
[tex] w = \frac{h - 3}{1.2} = \frac{12 - 3}{1.2} = 7.5 = 8 [/tex]
Therefore, it will take 8 weeks for the plant to reach one foot.
I hope it helps you!

Angle ABC is a right angle. The measure of angle ABD is 65 degrees. The measure of angle DBC is x degrees. What is the value of x?
Answer:
25 degrees
Step-by-step explanation:
Angle ABC is a right angle. This means it has a value of 90 degrees. When you add that to angle ABD, which has 65 degrees, you get 155 degrees. To find the measure of angle DBC you subtract 155 from 180. Your answer is 25 degrees.
Answer:
25 degrees
Step-by-step explanation:
Took the test
Your friend says that there is an angle whose measure is the same as the measure of the sum of its supplement and its complement.
Is your friend correct? What is the measure of the angle?
Let's check:
Let the angle be x
It's complement is 90-x
It's supplement is 180-x
x = 90 - x + 180 - x
x = 270 - 2x
3x = 270
x = 90
So the angle is 90, it's complementary is 0 and it's supplementary is 90... so 90 = 0 + 90
