If 2 inches on a map represents 75 miles how many does 8 inches represents
Answer:
Using a simple step-step expression we can identify that the right answer would be aprox 300 miles.
step-by-step explanation:
Make the problem into an expression.
2in=75miles
2/75=8/x
75*8=600
600=2x
x=300
Yesterday, Grace drove 38 1/2 miles. She used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallon is 30 3/5
miles per gallon
Step-by-step explanation:
To get the unit rate for miles per gallon, we simply divide the number of moles by the amount of gallons
Number of miles is 38 1/2 which is 77/2 miles
Number of gallons = 1 1/4 = 5/4
So unit rate will be;
77/2 divided by 5/4
= 77/2 * 4/5 = 154/5 = 30 3/5 miles per gallon

Write an equation that is parallel to y=4/5x+1?
Answer:
y=4/5×
Step-by-step explanation:
its parallel. U just have to leave the slope alone but find a different y intercept.
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y=\frac{4}{5}(x)[/tex]
Given :
Given the equation is [tex]y=\frac{4}{5}x+1[/tex]
the given equation is in the form of y=mx +b
where m is the slope and b is the y intercept
[tex]y=\frac{4}{5}x+1\\slope =\frac{4}{5}[/tex]
when two lines are parallel to each other then the slopes are equal
slope of parallel line = slope of given line
slope of parallel line =[tex]\frac{4}{5}[/tex]
When parallel lines passes through origin (0,0) the the equation of line parallel to [tex]y=\frac{4}{5}x+1[/tex] is
[tex]y-0=\frac{4}{5}(x-0)\\\y=\frac{4}{5}(x)[/tex]

2. Which part of the triangle is always directly
opposite the right angle?
Answer:
So BASically
A triangle has 3 sides
One is the hypotenuese
The other is the Base
and the last one is perpendicular
Step-by-step explanation:directly
opposite the right angle is The HYPOTENUESE
For any triangle, the longest side is always opposite the largest angle. The largest angle of a right triangle is always the 90 degree angle. If you had any larger angle, then the triangle wouldn't be a right triangle and instead it would be obtuse.
In a right triangle, the longest side is given the special name hypotenuse. The other sides of a right triangle are called the legs.

Find the measure of the angle.
I
[tex]4x - 5 = x + 16[/tex]
Subtract the sides of the equation plus 5
[tex]4x = x + 16 + 5[/tex]
[tex]4x = x + 21[/tex]
Subtract the sides of the equation minus x
[tex]3x = 21[/tex]
Divided the sides of the equation by 3
[tex] \frac{3}{3} x = \frac{21}{3} \\ [/tex]
[tex]x = 7[/tex]
So the measure of the angle equals :
[tex]4(7) - 5 = 28 - 5 = 23 [/tex]

At the end of the day, Mr. Díaz drains the pool. The equation
y = -50x + 300 can be used to find y, the number of gallons of
water left after draining the pool for x minutes. Graph the
equation. How long does it take to drain the pool? Explain.
Answer: 6 minutes.
Step-by-step explanation: You can use a graphing calculator to see the exact graph, but you're trying to figure out what value of x gives you a y of 0. -50 times 6 is 300, plus 300 equals 0.
The graph of the equation y = -50x + 300 is a straight line, and plotted below. The time it take the pool to drain, according to this equation, is 6 minutes.
How do we make graph of a function?Suppose the considered function whose graph is to be made is f(x)
The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values f(x) are plotted on the vertical axis.
They are together plotted on the point
(x,y) = (x, f(x))
This is why we usually write the functions as:
y = f(x)
For this case, we're specified that:
y = the number of gallons of water left after draining the pool for x minutes.The relationship between x and y given is: y = -50x + 300Take two different values of x, let it be 0 and 1.
Then, the value of y we get is:
Case 1: x = 0:[tex]y = -50x + 300\\y = -50 \times 0 + 300\\y = 300[/tex]
Thus, one point on the equation y = -50x + 300 is (0,300)
Case 2: x = 1:[tex]y = -50x + 300\\y = -50 \times 1 + 300\\y = 300 - 50 = 250[/tex]
Thus, another point on the equation y = -50x + 300 is (1,250)
Plot these points taking x on horizontal and y on vertical axis. Then join those two points by a straight line. This is the graph of the considered equation as equation of type [tex]y = mx +c[/tex] is a straight line's equation and for straight line, two of its points are sufficient to plot it.
The graph is given below.
Since we know that:
y = number of gallons of water left after draining the pool for x minutes,
so when the pool drains of fully, there will be no water left, or y = 0.
Putting y = 0 in the equation y = -50x + 300, we get:
[tex]y = -50x + 300\\0 = -50x + 300\\\\\text{Adding 50x on both the sides}\\\\50x = 300\\\\\text{Dividing both the sides by 50}\\\\x = \dfrac{300}{50}= 6[/tex]
Thus, when y= 0, we get x = 6, so when the fully filled pool is drained for 6 minutes, the whole pool gets drained (for this case).
Thus, the time it take the pool to drain, according to this equation, is 6 minutes. The graph of the equation y = -50x + 300 is given below.

I NEED HELP WITH THIS ASAP!!! FOR BRAINLIEST LASTQ
Answer:
A.
Step-by-step explanation:
It's literally the same equation written in reverse, which according to the commutative property, can be done.
Answer: A
Step-by-step explanation:
For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.
We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.
We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].
We can eliminate D because (-1×-7) given you 7, not -7.
Therefore, A is the right answer.
brainlllyy i need an answer what’s the slope of this line
Answer:
4/5
Step-by-step explanation:
The slope of the line is 4/5.
To find out the slope of a line, you must remember rise over run. Using that, you count up from whenever the line meets an actual whole number, which in this case it is -2, and then count up 4, and then you start counting right to meet the point (3, 4). The number of spaces you go to the right is 5, making the slope 4/5.
Hope this isn't too confusing and that it helps :)
