If a 130 mile trip takes 2 hours, what was the speed?
How long does a 35 mile trip at 70 mph take?
Answers
Answer:
Question 1's answer is 75 mph
Question 2's answer is 30 minutes
Step-by-step explanation:
Answer:
1. 65mph
2. 1/2 hour
Step-by-step explanation:
1. The equation is D=R×T. Since the distance was 130 miles and the time was 2 hours, rewrite the equation as 130=2R. Divide both sides by 2 and you get R=65
2. Using the equation, write 35 miles as distance and 70 mph as rate: 35=70T. Divide both sides by 70: T=0.5, which is equal to 1/2 hour, or 30 minutes.

help me plzz!
Answers
Answer: 1.5
Step-by-step explanation: Given:
A=1/10×5 + 11²
B= 5 - 11²
If c = A + B
c = ( 1/10×5 +11²) + ( 5 - 11² )
= ( 5/10 + 121) + ( 5 - 121)
= ( 121.5) + ( -120)
= 121.5 - 120

Answer:
I think e no answer is correct
Anything within parenthesis completed first. So 6(20+1) is equal to 6(21).
A isn’t right because 21-1=20. 6(20) is not equal to 6(21)
C isn’t right because 20-1=19. 6(19) and 6(21) aren’t equal.
E and D aren’t right because 3+2=5. 5(22) and 5(21) are not equal to 6(21).

A monkey is swinging from a tree. On the first swing, she passes through an arc of 10 m. With each swing, she passes through an arc 9/10 the length of the previous swing.
What is the total distance the monkey has traveled when she completes her 25th swing? Round your final answer to the nearest meter.
Answers
The total distance the monkey has traveled when she completes her 25th swing is 92.82 m if the monkey is swinging from a tree.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have:
A monkey is swinging from a tree. On the first swing, she passes through an arc of 10 m. With each swing, she passes through an arc 9/10 the length of the previous swing.
In first swing = 10 m
In second swing = (9/10)10 m = 9 m
In the second swing = (9/10)9 =81/10
10, 9, 81/10,..
This is the geometric sequence with the first term being 10 and the common ratio being 9/10.
a = 10
r = 9/10
The sum of geometric sequence up to 25th terms:
S = a(1 - rⁿ)/(1 - r)
S = 10(1 - (9/10)²⁵)/(1 - 9/10)
S = 92.82 m
Thus, the total distance the monkey has traveled when she completes her 25th swing is 92.82 m if the monkey is swinging from a tree. On the first swing, she passes through an arc of 10 m. With each swing, she passes through an arc 9/10 the length of the previous swing.

5. Rectangle ABCD is graphed in the coordinate plane. The following are vertices of the rectangle: A(-1,-6), B(-1,-7), C(1,7), and D(1,-6). Given these coordinates, what is the length of side AB in this triangle? On the lines below, provide the length of the side as well as your reasoning for how you arrived at your answer.
Answers
Answer:
The legnth of side AB would be 3 units
Step-by-step explanation:
First, you would determine that both point A and point B would have the same y-coordinate of 1. Then you would determine the difference between the x values of points A and B. Since 5 (the x-value for B) minus 2 (the x-value for A) is 3, the legnth of side AB would be 3 units.

William has a 26-liter glass tank. First, he wants to put some marbles in it, all of the same volume. Then, he wants to fill the tank with water until it's completely full. If he uses 85 marbles, he will have to add 20.9 liters of of water.
What is the volume of each marble?
How much water is necessary if William uses 200 marbles?
Answer: 0.06/marble | 14 liters
Answers
The volume of the marbles is 26-20.9 = 5.1 l and there ar e85 marbles
5.1/85 = .06 l/marble
then 200 marbles would requrie .06 l/marble x 200 marbles = 12 liters
so he would only need 26-12= 14 liters of water to fill the tank !

14 marbles

PLEASE HELP! If 2580 people watched one show and 2920 people watched another show. How many people need to watch the third show for there to be a 3000 people average attendance per show?
Answers
Answer:
3480
Step-by-step explanation:
Set it up so it looks like this.
(2580 + 2930 + x )/3 = 3000 Combine the terms on the left
(5510 + x) / 3 = 3000 Multiply by 3
5510 + x = 9000 Subtract 5510
x = 9000 - 5510
x = 3490
Does that really work?
2580 + 2930 + 3490 = 9000
Which says it does work.
1st show=2580
2nd show=2920
Add(+)=5,500
1st and 2nd show=5,500
Average ppl=3000
Subtract (-)= 2,500
Answer:2,500 people

Find the slope of the line that passes through the points A(–3, 1) and B(2, –5).
PLZ ANSWER ACCURATELY AND QUICKLY WILL MARK BRAINLIEST
Answers
Answer:
- 6/5
Step-by-step explanation:
To find the slope
m = ( y2-y1)/(x2-x1)
= ( -5-1)/(2- -3)
= (-5-1)/(2+3)
- 6/5
Answer:
-6/5 or -1 1/5
Step-by-step explanation:
The formula to find the slope with any 2 points of a line is rise/run, or
(y2-y1)/(x2-x1)
In this case, y2 is -5, y1 is 1, x1 is -3, and x2 is 2.
So, the slope is:
(-5-1)/(2-(-3))
-6/5 which, as a mixed number, is -1 1/5.
You can also graph out the points on a coordinate plane, draw the line between the points, and count the rise/run, but that might take a minute or two, which is not the best if you have a timed test.
