what is 3/4÷ 1/8? with a explanation
Answer:
The answer is 6.
Step-by-step explanation:
you have 3/4 divided by 1/8, first you find a common denominator, which is 8. Second you do 3 x 2 and 4 x 2, you should get 6/8 divided by 1/8, and 6 divided by 1 is still 6.
Answer:
6
Step-by-step explanation:
3 /4 × 8 /1 =
3×8/4×1=24/4
3x8 is the numerator 4x1 is the denominator
24/4=6
3/4÷1/8=6

A circle has a diameter of
18
m. Find the area of the sector
whose central angle is 135°
Answer:
[tex]\boxed {\boxed {\sf \frac{ 243}{8} \pi , 95.3775, or \ 95.42587686 \ m^2 }}[/tex]
Step-by-step explanation:
When given the central angle in degrees, the formula for sector area is:
[tex]A=\frac{ \theta}{360} * \pi r^2[/tex]
where θ is the central angle and r is the radius.
We are given the diameter, so we must calculate the radius. The radius is half the diameter.
r= d/2The diameter is 18 meters.
r= 18 m/2 r= 9 mNow we know all the variables:
θ=135 r= 9 mSubstitute the values into the formula.
[tex]A=\frac{ 135}{360} * \pi (9)^2[/tex]
Solve the exponent first.
(9)²= 9 m *9 m= 81 m²[tex]A=\frac{ 135}{360} * (81 \ m^2) \pi[/tex]
Solve the fraction.
[tex]A=\frac{ 3}{8} * (81 \ m^2) \pi[/tex]
Multiply the two rational numbers.
[tex]A=\frac{243}{8} \pi \ m^2[/tex]
The answer can be left like this, in terms of pi, or can be multiplied.
Using 3.14 as pi[tex]A=\frac{243}{8} *3.14 \ m^2[/tex]
[tex]A= 95.3775 \ m^2[/tex]
Using the pi button as pi[tex]A= 95.42587685 \ m^2[/tex]
The area is 243/8 π, 95.3775, or 95.42587685 square meters.

The area of a square carpet is 5476 sq.cm. Find the length of its side.
Answer:
Area of square = (side)^2 = 5476 sq.cm
side = √5476 sq.cm
side = √(74 cm)^2
side = 74 cm
Step-by-step explanation:
Answer:
74
Step-by-step explanation:
Since it's a square, all the sides are the same. Just square root 5476.
Hardy was given the scale drawing of the enlargement to find the scale factor and missing lengths. His work is shown below. Side A corresponds with 1.5, side B corresponds with 4, and a side with length 30 corresponds with a side with length 6. 1. Scale factor = StartFraction Scale drawing dimension over original dimension EndFraction = StartFraction 30 over 6 EndFraction = 5. Side A = 1.5 + 5 + 6.5. Side B = 4 + 5 = 9. Analyze Hardy’s work to determine if he is correct. If he is incorrect, what is his error? Yes. Hardy is correct. No. Hardy should have used the ratio of the original to the scale drawing to find the scale factor. No. Hardy should have multiplied by the scale factor to find the missing length. No. Hardy should have divided by the scale factor to find the missing length.
C. No. Hardy should have multiplied by the scale factor to find the missing length.

The value of the acceleration due to gravity is 9.8 m/s^2.
What is the acceleration due to gravity?Now we know that the acceleration due to gravity is the slope when you plot the graph of velocity against time for motion under gravity.
Now we must look at the data given and use;
v = u + at
Given that the object was dropped, u = 0 hence
v = at
at t = 1 s and v = 9.8 m/s
a = 9.8 m/s/ 1 s
a = 9.8 m/s^2
This value remains the same irrespective of the time that you pick hence it is the value of the acceleration due to gravity.

The time X it takes Hattan to drive to work on a randomly selected day follows a distribution that is approximately Normal with mean 15 minutes and standard deviation 6.5 minutes. Once he parks his car in his reserved space, it takes 5 more minutes for him to walk to his office. Let T = the total time it takes Hattan to reach his office on a randomly selected day, so T = X + 5. Describe the shape, center, and variability of the probability distribution of T.
Answer:
Shape: Approximately Normal
Center: 20 minutes
Variability: 6.5 minutes.
Using statistical concepts, it is found that the distribution is normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.
When a constant is added to a normal variable, the distribution remains normal and the standard deviation remains constant, while the constant is added to the mean.
In this problem, a constant of 5 minutes is added to a normal variable with mean of 15 minutes and standard deviation of 6.5 minutes, hence, the distribution is:
Normal, with mean (center) of 20 minutes, and standard deviation of 6.5 minutes.

Which statement best predicts the weather for Denver, Colorado on day 3.
Answer:
Denver should be experiences balmy weather on day 3. Temps vary depending on the month, but overall no storms, and fairly clear weather should be present.
Step-by-step explanation:
A higher pressure system is moving closer to Denver, making for sunnier and calmer weather. It also seems like the nice H should stick for around 2-5 days if the low and high pressure systems continue in what seems to be a slight loop, the low pressure system will probably be moving to the Northeast soon. Overall Denver should be experiencing nice weather, perhaps a bit colder because of the cold front that seems to have sweeped through before Day 1.
