The distance along a scenic route between two cities is 704 miles. One group of tourists left from the western end of the route at an average speed of 39 miles per hour. Another group left from the eastern end of the route at the same time, traveling in the opposite direction, with an average speed of 49 miles per hour. How long will it be before the two groups can expect to meet?
9514 1404 393
Answer:
8 hours
Step-by-step explanation:
The gap between the two groups is closing at the rate of (39 +49) = 88 mph.
At that rate, the 704-mile gap will be closed in ...
time = distance/speed
time = (704 mi)/(88 mi/h) = 8 h
The two groups will meet in 8 hours.
_____
Additional comment
Their meeting point will be (39 mi/h)(8 h) = 312 mi from the western end of the route.
length of the ribbon is 120 M. what is the length of 7/15 of the ribbon?
Answer:
56 M
Step-by-step explanation:
Reduce fractions to their lowest terms equivalents
Multiply the numerators and denominators of the fractions separately
[tex]\frac{7}{15}[/tex] * 120 = convert to fraction
[tex]\frac{7}{15}[/tex] * [tex]\frac{120}{1}[/tex] = convert to fraction
[tex]\frac{7 * 120}{15}[/tex] = apply fraction rule [tex]\frac{a}{b}[/tex] * [tex]\frac{c}{d}[/tex] = [tex]\frac{a * c}{b * d}[/tex]
[tex]\frac{7 * 120}{15 *1}[/tex] = apply rule a * 1 = a 15 * 1 = 15
[tex]\frac{120}{15}[/tex] = 8 divide the numbers
7 * 8 = 56 multiply the numbers

A circle has a Diameter of 8 what is the perimeter and area
Answer:
Area is 16 pi or about 50.27
Perimeter/circumference is 8 pi or about 25.13
Perimeter of a circle is basically the circumference. the formula of the circumference is 2 pi r. 2r = diameter
that means the circumference is 8pi or about 25.13
The formula for the area of a circle is pi r^2
The radius, or r is half the diameter. so 8/2 = 4 . The radius is 4
pi * 4^2
4^2 = 16
16 pi is the area or about 50.27

What is the value of x?
Enter your answer, as a decimal, in the box.
ft
Answer:
67.5 ft.
Step-by-step explanation:
Length of MA = 71.5 - 22 = 49.5 ft.
Length of BP = 97.5 - x.
So we have the equation:
22 / 49.5 = (97.5- x) / x
Cross multiply:
22x = 49.5(97.5 - x)
22x = 4826.25 - 49.5x
22x + 49.5x = 4826.25
71.5x = 4826.25
x = 4826.25/71.5
x= 67.5 ft.

Mark this and return
Answer:
The monthly net pay is [tex]\$1555[/tex].
Step-by-step explanation:
Step 1 :
Quintina decided to increase the deduction percentage of her federal income tax rate from [tex]14\%[/tex] to [tex]16\%.[/tex]
Quintina gross pay per month is [tex]\$2,100[/tex]
[tex]16\%[/tex] is written in the decimal form.

[tex]=0.16[/tex]
Federal income tax
[tex]=0.16[/tex] × Gross pay
[tex]=0.156[/tex] × [tex]2100[/tex]
[tex]=336[/tex]
Step 2:
Monthly net pay = Gross pay- Federal income tax - State Income Tax – social Security- Medicare.
[tex]=2100-336-89-85-35[/tex]
[tex]=2100-545[/tex]
[tex]=\$1555[/tex]
Therefore, the monthly net pay is [tex]\$1555.[/tex]

Answer: f(x+3) = -5x -9
Step-by-step explanation: Start by substituting (x+3) for x. When you do this, you'll get the answer
f(x + 3) = -5 (x + 3) + 6
When you multiply out the (x + 3) by the -5, you'll get an answer of (-5x -15), which gives you the full equation
f(x + 3) = -5x -15 +6
Now, you just have to combine the like terms of -15 and +6, or, 6-15, to get -9.
