Chen rode his skateboard 3 1/4 miles in 1/2 of an hour. What was his average speed in miles per hour.
Answer:
6.5 MPH
Step-by-step explanation:
Since he rode his skateboard for half an hour, you must multiply 2, that way he rode 1 hour. Since you multiply the 1/2 hour, you must also multiply 3 1/4, to get 6 1/2, or 6.5. Even though we know he didn't ride a full hour, if he had, and at the same rate, he would have rode 6.5 miles per hour.
Hope this helps! ;)

Answer:
p = q/(2 -3q)
Step-by-step explanation:
[tex]\dfrac{2p}{3p+1}=q \qquad\text{given}\\\\2p=q(3p+1) \qquad\text{multiply by the denominator}\\\\ 2p=3pq+q \qquad\text{eliminate parentheses}\\\\ 2p -3pq = q \qquad\text{subtract $3pq$}\\\\ p(2-3q)=q \qquad\text{factor out $p$}\\\\ \boxed{p=\dfrac{q}{2-3q}} \qquad\text{divide by the coefficient of p}[/tex]
Rashid can do a piece of work in 8 days, which Tipu can finish in 12 days. If they work on alternate days with Rashid Beginning, in how many days, the work will be finished?
Answer: 9.6 days
Step-by-step explanation:
Rashid can do a piece of work in 8 days. Rashid work rate will then be:
= 1/8 owe day.
Tipu can finish in 12 days. Tipu's work rate will be: = 1/12 owe day.
Their work rate together will then be:
= 1/8 + 1/12
= 3/24 + 2/24
= 5/24
From the calculation, together they will finish the work in:
= 1 ÷ 5/24
= 1 × 24/5
= 24/5 days
= 4.8 days
Busy since they are working on alternate days, then this will be multiplied by 2 which will be:
= 4.8 × 2
= 9.6 days

Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
x = −1
(x + 7)^2 – 11 = 0
lesser =
greater =
Answer:
Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317
Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683
Step-by-step explanation:
I am assuming you are asking for the lesser x solution and greater x solution.
(x + 7)^2 – 11 = 0
(x + 7)^2 = 11
x+7 = ±[tex]\sqrt{11}[/tex]
x = ±[tex]\sqrt{11}[/tex] - 7
Lesser = -[tex]\sqrt{11}[/tex] - 7 = -10.317
Greater = +[tex]\sqrt{11}[/tex] - 7 = -3.683
Answer:
lesser= -14
greater= 0 (:
What is the slope of the line that passes through the points (-2, 2), and (-4, -2)
Answer:
Step-by-step explanation:
(-2 - 2)/(-4 + 2)= -4/-2= 2 is the slope
y - 2 = 2(x + 2)
y - 2 = 2x + 4
y = 2x + 6 is the equation
Answer:
The slope is 2

Which values of a and b make the following equation true?
Answer:
a=11 , b=7
Step-by-step explanation:
When integer multiply with integer, the base were same, then we just add both powers.
for example

An ordinary dice is rolled. What is the probability that the number
of dots on the upper face is -
(a) 3
(c) an even no
(b) less than 3
(d) 7
Answer:
A) 1/6
B) 1/3
C)1/2
D) 1/6
Answer:
1/6 , 1/3 , 1/2 , 0Step by Step Explanation:An ordinary die has numbers from 1 to 6
Number of dots on the face = number that face represent
Dots on face can be 1 , 2 , 3 , 4 , 5 , 6
1. Number of 3 DotsProbaility = 1/6
2. Number of Dots less than 3 = 1 or 2 DotsProbability = 2/6 = 1/3
3 . An even number = 2 , 4 , 6Probability = 3/6 = 1/2
4 7 Dots not possible HenceProbability = 0

What is the difference in finding the exact vs approximate volume?
Answer:
An exact number is one that has no uncertainty. An example is the number of tires on a car (exactly 4) or the number of days in a week (exactly 7). An approximate number is one that does have uncertainty. ... The number can be the result of a measurement.

Which number line represents the solution to the inequality x - 3 > 2
Answer: x > 5
Step-by-step explanation: To solve for x in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.
Since 3 is being subtracted from x, we add 3 to
both sides of the inequality to get x > 5.
When graphing x > 5, we have an open circle on 5 and the
open circle tells us that 5 is not part of our answer.
Then we draw an arrow going to the right to represent
all possible solutions to this inequality, any number greater than 5.

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.
It tells you they are similar. This means the angles are the same, and the sides are proportionate.
Look at the 12 and 4 at the very bottom. This tells you the ratio of the sides. Since 12 / 4 = 3, you can find y with 2 * 3 which is 6.
From that, you also know that 3z = 3y - 2. Substitute the value of y in and you can find z.
Corresponding angles are exactly the same. which means, (3x)° = 100°
You should get x = 33 1/3, y = 6, z = 5 1/3
3. Plot the points and then answer the questions:
(1, -3) (-3, 9) (2,-6)
