When as rate, 100 miles in 5 hours would be ????? miles per hour
Answer:
20
Step-by-step explanation:
5 divided by 100 = 20
Answer:
20 miles per hour (20 mi/h)
Step-by-step explanation:
100 miles/5 hours = 20 miles/ 1 hour
(simplify the proportion)
Consider the following formula s=d/t, with
s being the speed, d as the distance, and t as the time.
this is because miles per hour is a measurement of speed.
In this case, 100 miles is the distance. 5 hours is the time, and we are solving for s.
s = 100/5, s = 20/1, s = 20 which is 20. So the rate or the speed is 20 miles per hour.
Anything multiplied or divided by 1 will remain the same.
Write the equation of the line that passes through (3, -2) and is parallel to y= 4x+1
Answer:
it should be y=4x-14
Step-by-step explanation:
since the line is parallel to y=4x+1 than the slope should be the same but the y intercept is different. and so u put the coordinate on a graph and use the slope and coordinate to fine the equation.
FIND THE DISTANCE BETWEEN EACH PAIR OF POINTS. ROUND TO THE NEAREST TENTH. (-4, 5) (4, 0)
Answer:
+9.4 to the nearest tenth
Step-by-step explanation:
(-4, 5) (4, 0)
Refering to the x-coordinates and the y-coordinates of these two points, we see that x changes from -4 to 4, a change of 8, which forms the horizontal leg of a right triangle. Simultaneously, y changes from 5 to 0, a change of 5, which forms the vertical leg. Now use the Pythagorean Theorem to determine the length of the hypotenuse of this triangle; this hypotenuse is the distance between the two points:
distance = +sqrt(8^2 + 5^2) = +sqrt(64 + 25) = + sqrt( 89) = +9.43 to the nearest hundredth and +9.4 to the nearest tenth.

|8x+3|=12 what’s the answer
Answer:
x= 9/8 , -15/8
Step-by-step explanation:
Answer:
x = 1.125 , x = 9/8
Step-by-step explanation:
|8x+3| = 12
=> 8x + 3 = 12
=> 8x = 12-3 = 9
=> 8x = 9
=> x = 9/8
As 9/8 is a fraction let's make it a decimal.
9/8 * 125/125 (To make it into a power of ten so that we can convert)
=> 1125 / 1000
=> 1.125

#2) A 12-ounce bag of marbles contains 64 marbles. Assume the relationship between weight and number of marbles is proportional. How much would you expect a bag of 160 marbles to weight (in ounces)? *
Answer:
Step-by-step explanation:
a 12 ounce bag = 64 marbles
So first you want to find out how much each marble weighs. To do this divide 12 ounces by 64.
1 marble = [tex]\frac{12}{64} = \frac{3}{16} ounces[/tex]
To find the weight of 160 marbles, you just multiply the weight of 1 marble by 160.
160 marbles = [tex]\frac{3}{16}[/tex] ×[tex]160[/tex] = 30 ounces.

Sam made a 70% on his test. If there were 80 questions on the test, how many did he get right?
Answer: He got 56 questions right.
Step-by-step explanation:
Answer:
Sam got 56 questions correct.
Step-by-step explanation:
If there were 80 questions on the test, sam got 56 correct in order to get a 70%.
To find this, you must find 70 percent of 80 questions. You first must turn 70% into a decimal, making it 0.70. You multiply this decimal by the 80 questions on the test. You then get 56. Meaning they got 56 right. I hope this helps!
