you ride your bike at an average of 12 miles per hour on the way to school, and at an average of 15 miles per hour on the way home. The total ride time is 22 minutes. How far away is school? Round your answer to the nearest hundredth of a mile
Answer: 2.44 miles.
Step-by-step explanation:Answer:
2.44 miles
Step-by-step explanation:
Give the following :
Average miles to school = 12 miles per hour
Average Miles from school = 15 miles per hour
Total ride time : ( time to school + time from school) = 22 minutes = (22/60) = 0.3667
Recall:
Speed = distance / Time
Time = distance / speed
Let distance = d
For the scenario described :
d/12 + d/15 = 0.3667
(5d + 4d) / 60 = 0.3667
5d + 4d = 22
9d = 22
d = 22/9
d = 2.44 miles

Which of the following is the equation of a line in slope-intercept form for a
line with slope = 1/4 and y-intercept at (0, -1)?
O A. y = 1/4 x -1/4
O B. y= 4x - 1
O C. y= 1/4x+1
O D. y = 1/4x-1
Answer:D
Step-by-step explanation: answer D. 1/4x-1
slope = 1/4 so the coefficent (number attatched to x) is going to be 1/4
y=-1 when x=0
A. =-1/4
B= -1 but the coefficent is not 1/4
C=1
D=-1
D is the correct answer

Please... Solve this: the bearing of a tree from a house is 295°. Find the bearing of the house from the tree.
Given parameters:
Bearing of the tree from the house = 295°
Unknown:
Bearing of the house from the tree = ?
Solution:
This is whole circle bearing problem(wcb). There are different ways of representing directions from one place to another. In whole circle bearing, the value of the bearing varies from 0° to 360° in the clockwise direction.
To find the back bearing in this regard, simple deduct the forward bearing from 360°;
Backward bearing = 360° -295°
= 65°
The bearing from house to the tree is 65°

Given a regular square pyramid with RS = 6 and PX = 4, find the following measure.
QS =
Answer:
The volume of a prism is given by ...
V = Bh
Step-by-step explanation:
Here, the base is an equilateral triangle with side length 3 in. The area of such a triangle is given by
A = (√3)4*s²
where s is the side length.
Your triangular prism has a base area of ...
B = (√3)/4*(3 in)² = (9/4)√3 in²
so the volume is
V = ((9/4)√3 in²)(6 in)
V = (27/2)√3 in³
V ≈ 23.383 in³

{2, 4, 5}
{2, 4, 5}
9514 1404 393
Answer:
{1, 5, 7}
Step-by-step explanation:
For x=0, y = 2·0 +1 = 1
For x=2, y = 2·2 +1 = 5
For x=3, y = 2·3 +1 = 7
The range is the list of y-values, so is {1, 5, 7}.
∠C and ∠D are complementary.

Complementary angles have sum 90°
[tex]\\ \rm\Rrightarrow 5x+7x-6=90[/tex]
[tex]\\ \rm\Rrightarrow 12x-6=90[/tex]
[tex]\\ \rm\Rrightarrow 12x=96[/tex]
[tex]\\ \rm\Rrightarrow x=8[/tex]
Answer:
x = 8
Step-by-step explanation:
Complementary angles are two angles with measures that sum to 90°
Given:
m∠C = (5x)° m∠D = (7x − 6)°⇒ m∠C + m∠D = 90°
⇒ 5x + 7x - 6 = 90
⇒ 12x - 6 = 90
⇒ 12x = 96
⇒ x = 8

What is 3/7 of $56
I am not sure
Answer:
$24
Step-by-step explanation:
1. MULTIPLY: 3 x 56 = 168
2. DIVIDE: 168 / 7 = $24
I hope this helps!
Based on multiplication we have found that 3/7 of $56 is equal to $24.
We are given that the expression 3/7 of $56
To determine 3/7 of $56, we can multiply 3/7 by $56.
Multiply 3/7 by $56:
(3/7) x $56 = (3 x $56) / 7
Calculate the numerator:
3 x $56 = $168
Divide the numerator by the denominator:
$168 / 7 = $24
Therefore, 3/7 of $56 is equal to $24.

Hello!!! Princess Sakura here ^^

Ok so since this is an area question we should begin with writing the correct formula for it. This says it's rectangular pool so we'll be using our rectangle formula, which is...

Now we plug in what we know...
[tex]length=30\frac{1}{3} \\width=12\frac{1}{2}[/tex]
Now we solve...

at the movies, la quinta paid for drinks and popcorn for herself and her two children. she spend twice as much on popcorn as on drinks. if her total bill came to $17.94, how much did she spend on drinks and how much did she spend on popcorn?
Answer:
Step-by-step explanation:
let the amount spent on popcorn be x and amount spent on drinks be y
If the total bill paid is $17.94, then x+y = $17.94
If she spend twice as much on popcorn as on drinks, then y = 2x
Substitute y = 2x into the original equation
x+y = $17.94
x + 2x = $17.94
3x = $17.94
x = $17.94/3
x = $5.98
Since y = 2x
y = 2($5.98)
y = $11.96
Therefore she spent $5.98 on popcorn and $11.96 on drinks

Answer:
[tex]x = 2 \sqrt{2} i \: or \: x = - 2 \sqrt{2} i[/tex]
Step-by-step explanation:
• Add 7 to both sides.
[tex]3x {}^{2} - 7 + 7 = - 31 + 7[/tex]
• Simplify
[tex]3x {}^{2} = - 24[/tex]
• Divide both sides by 3
[tex] \frac{3x {}^{2} }{3} = \frac{ - 24}{3} [/tex]
• Simplify
[tex]x {}^{2} = - 8[/tex]
• Find the solution
[tex]x = \sqrt{ - 8} \: and \: x = - \sqrt{ - 8} [/tex]
• Simplify
[tex] \sqrt{ - 8} = 2 \sqrt{2i} [/tex]
[tex] - \sqrt{ - 8} = - 2 \sqrt{2i} [/tex]

A random sample of 200 shoppers at a local grocery store found that 135 of the 200 sampled
would be willing to use self-checkout kiosks if the store installed them (ộ = 0.675).
Assuming you believe the initial results to be reasonable, how many samples would be required if
you wanted to re-do the sample, construct a 95% confidence interval, and reduce the margin of
error to 3%?
Round your answer to the nearest whole number. Remember: with sample sizes we always round
up!
Using the z-distribution, as we are working with a proportion, it is found that samples of 937 should be taken.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.The margin of error is given by:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In this problem, we have that:
The estimate is of [tex]\pi = 0.675[/tex].The margin of error is of M = 0.03.95% confidence level, hence[tex]\alpha = 0.95[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.95}{2} = 0.975[/tex], so [tex]z = 1.96[/tex].Then, we solve for n to find the minimum sample size.
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.675(0.325)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.675(0.325)}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.675(0.325)}}{0.03}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96\sqrt{0.675(0.325)}}{0.03}\right)^2[/tex]
[tex]n = 936.4[/tex]
Rounding up, it is found that samples of 937 should be taken.
