richard is walking around his neighborhood. if he walks 1/3 mile in 1/6 hour, how fast is richard walking, in miles per hour?
Answers
Answer:
2 miles per hours
Step-by-step explanation:
You divide 1/3 mile by 1/6 hour
Use the reciprocal.
1/3 x 6/1 = 2/1
Simplify
2/1 = 2
You can also solve it this way:
If 1/6 hour is 10 minutes, and it takes 10 minutes to walk 1/3 a mile, then it would take 30 minutes to walk a mile.
30 x 2 = 60
Either way, Richard walks 2 miles per hour.
Richard is walking at an average speed of 2 miles per hour which is the correct answer would be option (B).
What is Average speed?Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.
To determine how fast is Richard walking, in miles per hour
We have to calculate the average speed which is the ratio of the total distance traveled by a body to the total time
Total distance traveled by Richard = 1/3 mile
The total time taken = 1/6 hour
Average speed = the total distance / the total time
Average speed = (1/3) / (1/6)
Reciprocal the denominator term, and we get
Average speed = (1/3) × 6
Average speed = 2 miles per hour
Therefore, he is at an average speed of 2 miles per hour

Find the value of x.
x=
Answers
Answer:
x = 14
Step-by-step explanation:
These angles are complementary angles, meaning they have a sum of 90°.
4x + 1 + 2x + 5 = 90
6x + 6 = 90 (Added like terms.)
6x = 84 (Subtracted 6 on both sides.)
x = 14 (Divided 6 on both sides.)
[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]
It has a sum of 90 as the given angles are complementary angles.[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]
[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]
[tex]\sf \longmapsto6x + 6 = 90[/tex]
[tex]\sf \longmapsto6x = 90 - 6[/tex]
[tex]\sf \longmapsto \: 6x = 84[/tex]
[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]
[tex]\sf \longmapsto \: x = 14[/tex]

The slope is 3 true or false?
Answers
Answer:
The slope IS NOT 3.
So the statement is FALSE.
Step-by-step explanation:
y = mx + b
If we change the graph shown into the format shown above it would be:
y = 1x - 3
mx = slope
Slope = 1x
b = y-intercept
b = -3
To find the slope you must do:
[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]
y = rise
x = run
In the graph shown, the points are going up and shift to the right 1 unit.
So the slope is: 1x
Therefore, the statement, "The slope is 3" is actually false.

Step-by-step explanation:
We can use the slope formula to find the slope

y=8-X and y=5X-40
Answers
Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )

Lets solve your equation step-by-step
2(x+3)=x-4
Step 1 :Simplify both sides of the equation
2(x+3)=x-4
(2)(x)+(2)(3) =x+-4 (distribute)
2x+6=x+-4
2x+6=x-4
Step 2: Subtract x from both sides
2x+6-x=x-4-x
x+6=-4
Step 3: Subtract 6 from both sides
x+6-6=-4-6

Answers
Answer:
4w +7 = 5
Step-by-step explanation:
Have a nice day.
Answer:
4w + 7 = 5
Step-by-step explanation:
"sum" means addition (+), so we're to add two items:
item 1 to be added
"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).
Therefore, 4 x w = 4w
item 2 to be added
This is the number 7
The sum
4w + 7
Now, the sum, equals(=) the number 5, therefore answer:
4w + 7 = 5

The dimensions of a rectangular monitor screen are such that it's length is 5 in. More than it's width. If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in^2. What are the length and width of the screen?
Answers
Given:
Length of a rectangular monitor screen is 5 in more than it's width.
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
To find:
The length and width of the screen.
Solution:
Let width of the screen be x inches.
Length of a rectangular monitor screen is 5 in more than it's width. So,
Length of screen = (x+5) inches
Area of screen is
[tex]Area=length\times width[/tex]
[tex]A_1=(x+5)\times x[/tex]
[tex]A_1=x^2+5x\text{ in}^2[/tex]
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
New length = 2(x+5) inches
New width = (x-1) inches
So, new area is
[tex]A_2=2(x+5)(x-1)[/tex]
[tex]A_2=(2x+10)(x-1)[/tex]
[tex]A_2=2x^2+10x-2x-10[/tex]
[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]
Area increased by 170 in².
[tex]A_2-A_1=170[/tex]
[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]
[tex]2x^2+8x-10-x^2-5x=170[/tex]
[tex]x^2+3x-10=170[/tex]
Subtract 170 from both sides.
[tex]x^2+3x-10-170=0[/tex]
[tex]x^2+3x-180=0[/tex]
Splitting the middle term, we get
[tex]x^2+15x-12x-180=0[/tex]
[tex]x(x+15)-12(x+15)=0[/tex]
[tex](x+15)(x-12)=0[/tex]
[tex]x=-15,12[/tex]
Width cannot be negative. So, x=12.
Width = 12 inches
Length = 12+5 = 17 inches
Therefore, the length of screen is 17 inches and width is 12 inches.

Basic math equations and calculations play an important role in many jobs tasks. If you were working at a grocery store and your cash register was not automatically calculating the 20% off sale on someone's cereal--how would you solve this issue from the options listed below? If the cereal was normally $2.88, I would... 1 point Take $2.88 and times it by 80 for a sale price of $2.30. Subtract $0.20 for a sale price total of $2.68. Divide 20 from $2.88 for a sale price total of $0.15.
Answers
Given :
Price of cereal without off, C = $2.88 .
Percentage off, P = 20% .
To Find :
Price after applying 20% off.
Solution :
Final price = Initial price - 20 % of initial price
[tex]F = 2.88 - 2.88\times \dfrac{20}{100}\\\\F=2.88-0.576\\\\F=\$ 2.304[/tex]
Therefore, final price after sale is $2.304 .
Hence, this is the required solution.
