10). A boat traveled 27 miles in 2 hours. At
this rate, how many miles will the boat
travel in 0.5 hour?
Answer:
6.75 miles per 0.5 hours.
Step-by-step explanation:
The ratio 27/2 is equal to the ratio of 6.75/0.5. This can be shown by dividing the 2 in the denominator by 4, getting you 0.5, and dividing the numerator, 27, by 4 also, which gets you 6.75. Hope this helps!

Which expression represents the volume of this prism?
2 x 8 units
1 x 8 units
2 x 4 units
4x8 units
Answer:
Option AStep-by-step explanation:
We know that:
Volume of prism: L x B x HW = 8 unitsL = 2 unitsH = 1 unitSolution:
L x W x H=> 2 x 8 x 1=> 2 x 8=> 16 units³Looking at the options, we can see that our result matches with Option A.
Hence, Option A is correct.
We know for any prism the volume formula is
[tex]\\ \tt\hookrightarrow Area\:of\:base\times Height [/tex]
Area of base=1×2=2unitsVolume:-
[tex]\\ \tt\hookrightarrow 2(8)units^3[/tex]

Answer:
the answer for the fifth side would be 9 inches.
Step-by-step explanation:
if you know that two sides are 5 inches long and the other two sides are 4 inches long then add 5+5+4+4 which equals 18 so then subtract 27 from 18 and you get 9 which is the length of the last side. 9 inches. I hope this helps
Answer:
9 in
Step-by-step explanation:
The sum of the five sides = 27 in
We know that 2 sides are 5 in and 2 sides are 4 in
Let x be the length of the fifth (unknown) side
Therefore, 5 + 5 + 4 + 4 + x = 27
Combine like terms: 18 + x = 27
Subtract 18 from both sides: x = 9
Therefore, the fifth (unknown) side is 9 in long
Rip van Winkle fell asleep for a very long time. When he fell asleep, his beard was 8 millimeters long, and
each passing week it grew 2 additional millimeters.
Graph the relationship between the length of Rip van Winkle's beard (in millimeters) and time (in weeks).
Step-by-step explanation:
According to question, the initial value, the y-intercept is b = 8 and the rate of change, the slope is m = 2.
This gives us the equation:
y = 2x + 8Plot the y-intercept (0, 8) and one more point:
x = 1 ⇒ y = 2+ 8 = 10Connect the points to get the line.

The two triangles are similar. What is the scale factor from the smaller
triangle to the larger triangle?
8 cm
9 cm
10 cm
Smaller
18 cm
14.4 cm
16.2 cm
Larger
Answer:
The scale factor for the triangles (larger/smaller) = 6/2 = 3.
The area of the larger triangle equals the area of the smaller triangle times the square of the scale factor (32 = 9):
Area of Larger Triangle = Area of Smaller triangle * Scale Factor 2 = (3 cm2)*9 = 27 cm2.

For what value of X must ABCD be a parallelogram?
Answer:
x = 3
Step-by-step explanation:
A parallelogram must have two pairs of parallel sides.
For this to be true, the alternate exterior angles of the diagonal must be congruent.
Hence the equation,
10x + 4 = 13x - 5
Simplify.
9 = 3x
x = 3
The difference between two numbers is 40. Twice the first number plus three times the second number
is 100. Find the numbers. Provide a full solution.
Answer:
x = 44 and y = 4
Step-by-step explanation:
Given:
x - y = 40
2x + 3y = 100
Isolate for x in the first equation:
x = 40 + y
Sub x = 40 + y into the second equation and solve for y:
2(40 + y) + 3y = 100
80 + 2y + 3y = 100
5y = 20
y = 4
Sub y = 4 into the equation for x:
x = 40 + 4
x = 44
Therefore, x = 44 and y = 4
The recyclables have been sorted into plastic and glass. The number of plastic items is 30 less than nine times the number of glass items. The recyclables are 85% plastic. How many glass items are there?
PLEASE HELP ASAP
Answer:
B, 9
Step-by-step explanation:
Let g represent the number of glass items. Then the number of plastic items is (9g -30). If 85% of items are plastic, then 100%-85% = 15% of items are glass. The ratio of plastic to glass is ...
85%/15% = (9g -30)/g
17/3 = 9 -30/g . . . . simplify
30/g = 9 -17/3 = 10/3 . . . . . . add 30/g -17/3
g = 30(3/10) = 9 . . . . . . . . . . multiply by 3g/10
There are 9 glass items.
_____
Additional comment
The number of plastic items is 9(9) -30 = 51, and the total number of items is 51+9 = 60. The percentage of plastic items is 51/60 = 85%.
__
There are many other ways the equation(s) could be written, including using a system of two equations. For example ...
p = 9g -30p/(p+g) = 0.85 . . . . . plastic is 85% of the totalExplain how to determine if the number is a solution to the equation.
56 = 8n for n = 6
Answer:
Substitute 6 for the variable, n, using parentheses. Then simplify by multiplying 8 and 6. 8(6) = 48. So you have 56 = 48, which is not a true statement. 6 is not a solution to the equation.
Step-by-step explanation:
Answer:
False.
Step-by-step explanation:
Question: 56 = 8n for n = 6
8 *6 = 56
48 = 56
False, the solution to this equation is not applicable.Find the amount of money accumulated after investing a principle P for years t at interest rate r, compounded continuously. P = $3,200 r = 8% t = 4
