Snail will have to travel shortest distance of (C) 11 cm
The shortest distance between vertex A and vertex B will be the line directly joining the two points. This line is called diagonal and is related with length, width and height by the formula -
Diagonal = ✓(l² + w² + h²), where l represents length, w represents width and h represents height. Keep the values in formula -
Diagonal = ✓(4² + 4² + 10²)
Taking square of the number
Diagonal = ✓(16 + 16 + 100)

5. Charnita Jones earns $304.80 per week as a sales assistant. Next week she will be
promoted to assistant manager. She will then earn $332.50 per week. She is single
and claims 1 allowance. How much more will she pay in federal income tax?
Charnita Jones will have to pay $5 more in federal income tax.
According to the question we have been given that Charnita Jones
As sales assistant she earned = $304.80
After promotion as assistant manager she will earn = $332.50
Number of allowance she claims = 1
We need to find how much more she will pay in federal income tax.
For that we will first calculate how much she paid when her earning was $304.80. For this we will use the table for single persons-weekly payroll period. In that table, first we will choose the row of wages from the column number 1. We look to that row where $304.80 will lie that is the row will be $300-$310. then we will look for allowance that is 1. Thus the tax she will pay will be in column of allowance 1 and in the row of $300-$310 is $22.
In similar way we will find out the tax she will pay when she earn $332.50 which is $27.
Difference = $27 - $22 = $5
Hence she will have to pay $5 more in federal income tax.

What do you mean by the unitary method?The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
As a result, multiplying by 2, the man travels 3.5 miles in one hour.
The distance the man walks in 7 hours, multiplied by 7, comes out to be 24.5 miles. Alternatively, you might divide the man's distance traveled by 7, or X, to get 7 (x/7). It equals the time needed to travel X miles, which is 2 hours (7/2), divided by the time needed to go X miles, which is 7 hours. X, therefore, equals 24.5 miles.

The Perimeter of the polygon = 22.43 units.
How to Determine the Perimeter of a Polygon?Given the vertices of the polygon as:
U(-2,4)V(3,4)W(3,-4)The perimeter of the polygon is the sum of all its sides, UV + VW + UW.
Apply the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find the length of each of the three sides of the polygon as shown below:
UV = √[(3−(−2))² + (4−4)²]
UV = √[(5)² + (0)²]
UV = √25
UV = 5 units
VW = √[(3−3)² + (4−(−4))²]
VW = √64 = 8 units
UW = √[(−2−3)² + (4−(−4))²]

You average 55 miles per hour while driving to a relative's house. On the return trip, you average 50 miles per hour because of bad weather. The total driving time is 5 hours and 15 minutes. How long does each trip take?
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.
How long does each trip take?
Remember the relation:
Distance = Speed*Time.
Here the total distance of the trip is 55mi + 50mi = 105mi
And the total time is 5 hours and 15 minutes, remember that:
60 min = 1 hour
Then; 15 min = 0.25 hours.
So the total time is 5.25 hours, with that we conclude that the average speed is:
S = 105mi/5.25 h = 20 mi/h
The first trip is 55 miles long, then the time in which it is travelled is:
T = (55 mi)/(20 mi/h) = 2.75 hours
The second trip is 50 miles long, then:
T' = (50mi)/(20 mi/h) = 2.5 hours.
We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

An airplane leaves Los Angeles and travels 5 hours to New York City. The return trip travels along the same route and takes 6 hours because the plane travels 99 mph slower due to a headwind. Find the distance the plane flies between the two cities.
Using the relation between velocity, distance and time, the distance of the plane ride between Los Angeles and New York is of 270 miles.
What is the relation between velocity, distance and time?Velocity is distance divided by time, hence the following equation is built to model the relationship between these variables:
v = d/t.
For the Los Angeles to New York trip, we have that the time is of 5 hours, hence:
v = d/5.
v = 0.2d.
For the return trip, we have that the time is of 6 hours, while the velocity is 99 mph slower, hence:
v - 99 = d/6.
From the first equation, we have that:
v = 0.2d.
Replacing on the second:
0.2d - 99 = d/6.
d(0.2 + 1/6) = 99
0.3667d = 99
d = 99/0.3667
d = 270 miles.
The distance of the plane ride is of 270 miles.

a) y=-x+5
b) y=-x-2
c) y= 4x + 2
d) y=-4x-4
Answer: Any line with slope of -3/4
Reason:
Let's calculate the slope of the line through those two points
[tex](x_1,y_1) = (1,3) \text{ and } (x_2,y_2) = (4,7)\\\\m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}\\\\m = \frac{7 - 3}{4 - 1}\\\\m = \frac{4}{3}\\\\[/tex]
The slope of the line is 4/3
Anything perpendicular to this has a slope of -3/4. I flipped the fraction and flipped the sign (from positive to negative).
So for example, the answer may be something like [tex]y = -\frac{3}{4}x+5[/tex] or [tex]y = -\frac{3}{4}x-2[/tex]. All that matters is the -3/4 out front of the x.
Side note: the original slope 4/3 and perpendicular slope -3/4 multiply to -1

Pls answer asap 100 points
Step-by-step explanation:
To tell if something is longer than another object is to find the difference between the two objects.
If the difference is < 0, then the object is shorter
If the difference is = 0, then the objects are equal in length
If the difference is > 0, then the object is longer
[tex]6.5 * 10^{-9}[/tex] - [tex]4.75 * 10^{-9}[/tex] = [tex]1.75*10^{-9}[/tex]
The difference is > 0, so the wavelength is longer.

If the grid and tanya start typing at the same time, tanya have typed 14.67 pages.
What is the ratio?A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.
Now it is given that,
Pages typed by Ingrid = 3
Pages typed by Tanya = 4
So, the ratio of pages, Ingrid : Tanya = 3 : 4
So, If the grid and tanya start typing at the same time Ingrid has typed 11 pages
Thus, dividing the ratio be 3 we get,
3 : 4 = 1 : 1.33
Now for 11 pages multiplying 1.33 with 11 we get,
