Please help me with my homework please
Solution:
1)Distance covered by cyclist=3.75 miles.
Time =0.3 hours.
Speed= Distance ÷Time
Speed =3.75÷0.3=12.5 miles per hour.
2) Speed = 12.5 miles per hour, Distance = 4.5 miles .
Time = Distance ÷Speed.
Time = 4.5÷12.5=0.36 hours.
Time taken to cover 4.5 miles is 0.36 hours.
Answer:
a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.
b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.
Remember: Speed=Distance/TimeWhat is the value of x? Enter your answer in the box.
Answer:
I believe the answer is 128 degrees.
Step-by-step explanation:
x is congruent to 128 because they are vertical angles.

Mrs. Sanders can clean the windows of her house in
3 hours. Her daughter can clean the windows in 6 hours.
How long will it take them to clean the windows if they
work together?
9514 1404 393
Answer:
2 hours
Step-by-step explanation:
Mrs. Sanders cleans 1/3 of the windows per hour. Her daughter cleans 1/6 of the windows per hour. Working together, they clean 1/3 +1/6 = 1/2 of the windows per hour.
It will take them 2 hours to finish when they work together.

After charging for LaTeX: \frac{1}{3} of an hour, a phone is at LaTeX: \frac{2}{5} of its full power. A) How long will it take the phone to charge completely? B) Write a multiplication and division equation for this situation.
Answer:
Find the solution below
Step-by-step explanation:
A) Let the complete power of the phone be 1
If after charging 1/3 of an hour, a phone is at 2/5 of its full power, we can write;
1/3 hr = 2/5 of its full power
To determine the time it will take to phone to charge completely, we will say;
x hr = 1
Divide both expression
(1/3)/x = 2/5
1/3x = 2/5
Cross multiply
1 * 5 = 3x * 2
5 = 6x
x = 6/5
x = 1.2
Hence it will take 1.2 hour for the phone to charge completely
B) From the expression in A
1/3x = 2/5
Multiply both sides by 3
1/3x * 3= 2/5 * 3
x = 2/5 * 3
Hence the multiplication equation is x = 2/5 * 3
Also divide both sides by 1/3
recall 1/3x = 2/5
1/3x ÷ 1/3 = 2/5÷1/3
x = 2/5÷1/3
Hence the division equation is x = 2/5÷1/3

At Adam's Hats, there are 52 baseball caps and 13 other hats. What percentage of the hats are baseball caps?
Total hats = 52 + 13 = 65
Percentage that are baseball = number of baseball/ total hats x 100.
52/65 = 0.8 x 100 = 80%
80% are baseball hats
Answer: 80%
Step-by-step explanation:
First, you would add 52 and 13 together. That would be 65. Then you would divide 52 by 65. The answer is 0.8. That is equal to 80%.

A local grocery store conducted a random survey on the types of yogurt customers bought. The chart shows the survey results. Based on the survey, which percent of yogurt sold at the grocery store should be Greek yogurt?
The chart relating to the question can be found in the picture attached below :
Answer:
40%
Step-by-step explanation:
Yoghurt __________ No of responses
Low Fat ___________ 15
Greek_____________24
Whipped __________ 10
Regular ___________ 11
Total number of responses :
(15 + 24 + 10 + 11) = 60
Number of responses for Greek yogurts = 24
Percentage % :
(Greek Yoghurt responses / total responses) * 100%
= (24 / 60) * 100%
= 0.4 * 100%
= 40%

9514 1404 393
Answer:
C
Step-by-step explanation:
The problem statement tells you that cost is a function of x minutes. We plot the independent variable (x) on the horizontal axis, so this statement tells you the horizontal axis will be labeled "Minutes." (matches A and C)
When x=0 (no minutes), the function value is ...
c(0) = 3·0 +2 = 2
For each additional minute, the cost goes up by 3, so we know these things about the line:
the y-intercept c(0) is 2the slope is 3 = rise/runThe graph of A has a y-intercept of 3, so is incorrect. It also has a slope of 2, so is incorrect on that basis, as well.
The graph of C is the correct choice.
Someone please help iff your good at math:)
Identify the function shown in this graph.
O A. y = 3x - 1
O B. y = x +1
O c. y = 3x + 1
O D. y=-3x+1
Answer:
C. y=3x + 1
Step-by-step explanation:
What is the slope of the line?
Answer:
the slope is -2
Step-by-step explanation:
When using rise over run you must divide the Y (in this case it's 2) by the X (which is 1), and in this problem 2 divided by 1 equals 2, but it's a negative line because it's going down which means your answer is -2

Kevin drove 871 miles in 13 hours. At the same rate, how many miles would he drive in 11 hours?
Answer:
737 miles
Step-by-step explanation:
So we know that he drove 871 miles in 13 hours so first you want to do 871 divided by 13 and get 67 which means he drove 67 miles in one hour. Finally you just have to multiply 67 by 11 and get 737.
Answer:
737 miles
Step-by-step explanation:
Since the distance is gonna be less it's gonna be..
11 x 871/ 13
Determine the intercepts of the line.
y + 5 = 2(x+1)
y-intercept:
X-intercept:
Answer:
Y intercept: -3
X intercept: 1.5
Step-by-step explanation:
Find the y intercept by setting x equal to 0 and solving for y:
y + 5 = 2(x + 1)
y + 5 = 2(0 + 1)
y + 5 = 2(1)
y + 5 = 2
y = -3
Find the x intercept by setting y equal to 0 and solving for x:
y + 5 = 2(x + 1)
0 + 5 = 2(x + 1)
5 = 2(x + 1)
5 = 2x + 2
3 = 2x
1.5 = x
So, the y intercept is -3 and the x intercept is 1.5

Answer:
[tex]y=\frac{9\sqrt{3} }{2}[/tex] or 7.79 x= 9/2 or 4.5
explanation:
This is a special right triangle; a 90-60-30 triangle.
The side labelled y = a, side labelled x is equal to [tex]a\sqrt{3}[/tex], and the hypotenuse equals 2a.
First solve for a. [tex]9\sqrt{3}=2a[/tex] [tex]a=\frac{9\sqrt{3} }{2} =y[/tex] and that gives you y.
Then use a to find x. [tex]a\sqrt{3} =x[/tex] so [tex]\frac{9\sqrt{3} }{2} *\sqrt{3} = 9/2=4.5[/tex]
1/2x-7=1/3(x-12) can someone please help me I have a math test dueeee
Answer:
The correct answer is,
[tex]x = 18[/tex]
Answer:
x = 18
Step-by-step explanation:
So first you want to get rid of the fractions, which are 1/2 and 1/3. To do this you can multiply both sides of the equation by 6, so you would get:
3x - 42 = 2(x - 12).
Next, on the right side of the equation you can distribute the 2.
3x - 42 = 2x - 24
You want to get all the x variables on one side so you can subtract 2x from both sides.
x - 42 = -24
And finally you add 42 to both sides
x = 18
