67 miles
Step-by-step explanation:
An odometer measures the distance traveled by a vehicle.
To calculate the number of miles Mr Chin drove that day, subtract the reading of the odometer at the start of the day from the reading of the odometer at the end of the day.
Given information:
Starting odometer reading = 47 milesEnding odometer reading = 114 miles⇒ Number of miles driven = 114 - 47

So far, a storm has traveled 35 miles in half an hour. If it is currently 5:00 pm and the storm is 105 miles away, what time will the storm reach you? Explain how you solved the problem.
Answers
Answer:
It will reach you at 6:30.
Step-by-step explanation:
THe storm traveled at 35 miles in half an hour. It is 105 miles away.
Divide 105 by 35 to get how many half hours it will take to rach you.
105 ÷ 35 = 3.
So, it will be 3 half hours or one hour and a half.
Add that time to the current time, which is 5:00.
It will be 6:30 when the storm reaches you.

maria , an experienced shipping clerk, can fill a certain order in 12 hours. , a new clerk, needs 13 hours to do the same job. Working together, how long will it take them to fill the order
Answers
It would take them approximately 6.24 hours (or 6 hours and 14 minutes) to complete the order if they work together.
To solve this problem, we can use the formula:
Time = Work ÷ Rate
Time is the time it takes to complete the job, Work is the amount of work to be done, and Rate is the rate of work.
Let's assume that the amount of work to be done is 1 (it doesn't matter what unit we use as long as we are consistent).
Then, Maria's rate of work is 1/12 (she can do 1 job in 12 hours) and the new clerk's rate of work is 1/13 (he can do 1 job in 13 hours).
If they work together, their combined rate of work is the sum of their individual rates:
Rate = Maria's rate + New clerk's rate
Rate = 1/12 + 1/13
Rate = (13 + 12) / (12 x 13)
Rate = 25 / 156
So, their combined rate of work is 25/156 jobs per hour.
Now, we can use the formula to find the time it takes for them to complete the job together:
Time = Work ÷ Rate
Time = 1 ÷ (25/156)
Time = 156/25

A mountain bike is priced at $413. If the sales tax is 6.5 percent, what is the cost to purchase the mountain bike? Round to the
nearest cent if necessary.
$26.85
$28.91
$437.78
$439.85
Answers
answer: D) 439.85
Step-by-step explanation:
we are given the price of the bike which is $413.
we are also given the sales tax which is 6.5%.
sales tax is added to the original price to give us our total. so in order to find the total cost we need to find what the 6.5% sales tax is and add it to our original price. to find the sales tax number in dollars we need to set up our formula. The easiest formula is to use a proportion. X is out of 413 = 6.5% is out of 100%. X/413=6.5/100. We can then cross multiply then divide. 6.5 times 413=2,684.5. then divide 2684.5÷100= 26.845.
we need to round up to the nearest cent since we are working with dollars and cents 26.85. 26.85 is 6.5% of the price of the bike which is 413. Now we just simply add the tax to the original price and we get the cost. 413+26.85=439.85

Find the area, in square inches, of the composite figure.
A composite figure consisting of an isosceles right triangle, a rectangle, and an another isosceles triangle. The combined length of the right triangle and the rectangle is 25 inches. The length of only the rectangle is 14 inches. The base of the other isosceles triangle, which is the same as the width of the rectangle, is 2 inches plus 2 inches, and the height of the isosceles triangle is 3 inches.
Answers
The area of the composite figure is 122.5 square inches
How to find the area of the composite figure.Based on the problem statement, we have the following dimensions from the question
Isosceles right triangle: 11 inchesRectangle: 14 inches by 4 inchesAnother isosceles triangle; Base = 4 inches and Height = 3 inchsThe area of the composite figure is the sum of individual areas
So, we have
Area = Isosceles right triangle + Rectangle + Another isosceles triangle
By applying the formulas, we have
Area = 0.5 * 11 * 11 + 14 * 4 + 0.5 * 4 * 3
Evaluate
Area = 122.5

Find the measure of angle y. Round your answer to the nearest hundredth. (please type the numerical answer only)
Answers
Answer:
y° = 11.54
Step-by-step explanation:
Because this is a right triangle, we can find the measure of angle y using inverse trigonometry.When angle y is the reference angle:
the side that is 4 units long is the opposite side,and the side that is 20 units long is the hypotenuse (i.e., the side always opposite the right angle).Thus, we can use the inverse sine ratio, which is given by:
sin^-1 (opposite / hypotenuse) = θ, where
θ is the reference angle.Thus, we plug in 4 for the opposite side and 20 for the hypotenuse:
sin^-1 (4 / 20) = θ
sin ^-1 (1 / 5) = θ
11.53695903 = θ
11.54 = θ
Thus, the measure of y is 11.54.
You pick 7 digits (0-9) at random without replacement, and write them in the order picked. What is the probability that you have written the first 7 digits of your phone number? Assume there are no repeats of digits in your phone number. Give your answer as a fraction.
Answers
The probability of writing the first 7 digits of your phone number is 1/604,800.
Given data ,
To determine the probability of writing the first 7 digits of your phone number, we need to consider the total number of possible outcomes and the favorable outcomes.
Total number of possible outcomes:
When picking 7 digits without replacement from the set of 10 digits (0-9), the total number of possible outcomes is given by 10P7 (permutations of 10 objects taken 7 at a time):
10P7 = 10! / (10 - 7)! = 10! / 3! = 10 * 9 * 8 * 7 * 6 * 5 * 4 = 604,800.
Favorable outcomes:
To have written the first 7 digits of your phone number, you need to pick those specific digits in the correct order. Since the phone number has no repeated digits, there is only one specific order that satisfies this condition.
Therefore, the number of favorable outcomes is 1.
Probability:
The probability is given by the ratio of favorable outcomes to total possible outcomes:
Probability = Favorable outcomes / Total possible outcomes
= 1 / 604,800.
Hence, the probability is 1/604,800.

Complete the general form equation of the parabola that passes through (4,101) with vertex at (−3,3) .
f(x)=
Answers
Answer:
f(x) = 2x²+12x+21
Step-by-step explanation:
1. Start with Vertex Form: y = a(x-h)²+k; Vertex (h,k)=(-3,3):
y = a(x + 3)²+3
2. Replace x and y with (x,y)=(4,101) in your step 1 equation:
101 = a(4+3)²+3
3. Simplify the right side and solve for a:
101 = 49a+3
49a = 98
a = 2
4. Replace a with 2 in your step 1 equation:
y = a(x + 3)²+3 ⇒ y = 2(x + 3)²+3
5. Follow Order of Operations to convert step 4 equation to Standard Form: (x + 3)² = x²+6x+9
2(x²+6x+9) = 2x²+12x+18
2x²+12x+18 + 3 = 2x²+12x+21

Answers
The equation is correct, and the value on both sides of the equation is 40.
To verify if the equation 90 × 4/9 = 40 is true, we can perform the calculation on both sides and compare the results.
On the left side of the equation:
90 × 4/9 = (90 × 4) / 9 = 360 / 9 = 40
On the right side of the equation:
40
Both sides of the equation evaluate to 40, which means they are equal. Therefore, the equation 90 × 4/9 = 40 is indeed true.

Answer:
\(\sf \angle PDT \cong \angle XF\:\!K\)
\(\sf m\angle PDT = m\angle XF\:\!K\)
Step-by-step explanation:
From inspection of the given diagram, we can see that ∠NAZ is congruent to ∠YBR, since they are both labelled 47°.
We use identical tick marks to indicate congruent angles. Therefore, as ∠NAZ and ∠MCS both have one tick mark, this means they are congruent. So the measure of ∠MCS is also 47°.
The remaining two angles, ∠PDT and \(\sf \angle XF\:\!K\), do not have a tick mark. This indicates that these angles are congruent (and different to the other three angles).
The symbol ≅ is used to show congruency. If we want to represent angle PDT is congruent to angle \(\sf XF\:\!K\), we write it as \(\sf \angle PDT \cong \angle XF\:\!K\).
This literally means "angle PDT is congruent to angle \(\sf XF\:\!K\)".
If two angles are congruent, then their angle measures are equal.
When the angle measures are equal we write it as \(\sf m\angle PDT = m\angle XF\:\!K\).
The "m" means "measure", the "∠" means "angle", and "=" means "is equal to". So \(\sf m\angle PDT = m\angle XF\:\!K\) means "the measure of angle PDT is equal to the measure of angle \(\sf XF\:\!K\)".
