A car is travelling with uniform acceleration along a straight road. The road has marker posts every 100m. When the car
passes one post, it has a speed of 10ms-and, when it passes the next one, its speed is 20ms-1.
What is the car's acceleration?
A 0.67ms-2
B 1.5ms-2
C 2.5ms-2
D 6.0ms?
Answer:
(B)
Step-by-step explanation:
v^2 = v0^2 + 2ax
a = (v^2 - v0^2) / 2x
= (20^2 - 10^2) / 200
= 1.5 m/s
Answer the questions below
Answer:
#1At the start the total number is 10, male fish = 6
P(m) = 6/10 = 3/5At the second time the total number is 9, male fish = 5
P(m) = 5/9Probability of two male fish is:
P(m and m) = 3/5*5/9 = 1/3#2a) The events are independentb) P(4 and A) = 1/6*1/4 = 1/24c) P(an even number and C) = 1/3*1/4 = 1/12d) P(2 or 5 and B or D) = (1/6 + 1/6)*(1/4 + 1/4) = 1/3*1/2 = 1/6#3P(both goals) = 0.8*0.8 = 0.64The length of each of the legs of an isosceles triangle is represented by the
expression 6x – 2 inches. The length of the base of the isosceles triangle is
represented by the expression 3x + 1 inches. The perimeter of the isosceles
triangle is 42 inches. What is the length of the base?
Answer:
10 inches
Step-by-step explanation:
6x-2+6x-2+3x+1=42
12x-4+3x+1=42
15x-3=42
15x=45
x=3
Plug x=3 into 3x+1
3*3+1
9+1=10
Length of base is 10 inches
Isabella is bouncing a rubber ball that has a density of 1.5 g/cm3 . The rubber ball has a volume of 113 cm³.
What is the mass of the rubber ball?
Answer:
The mass of the rubber ball is 169.5g
Step-by-step explanation:
we know that
The density is equal to the ratio of the mass by the volume
D=m/V
Solve for m
m=D*V
In this problem we have
V=113 cm^3
D=1.5 g/cm^3
substitute
m.1.5*113=169.5g

Paul and Tammy went out to dinner and the total of their meals was $37.85. Paul spent $12.55 less than what Tammy spent. How much did Paul spend?
Answer:
Paul spent $12.65
Step-by-step explanation:
Create a system of equations where p is how much Paul spent and t is how much Tammy spent.
p + t = 37.85
p = t - 12.55
Solve by substitution:
p + t = 37.85
(t - 12.55) + t = 37.85
2t - 12.55 = 37.85
2t = 50.4
t = 25.2
Find how much Paul spent by plugging in 25.5 as t into p = t - 12.55
p = t - 12.55
p = 25.2 - 12.55
p = 12.65
So, Paul spent $12.65

Find the equation of the line that goes through the point (4, -3) and has a slope of 0.
Answer:
y = - 3
Step-by-step explanation:
A line with a slope of 0 is horizontal and parallel to the x- axis with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (4, - 3 ) with y- coordinate - 3, then
y = - 3 ← equation of line

Answer:
1. 30 in
2. 273 mi
3. 248 m
Step-by-step explanation:
For the first circle, you are given the radius. Multiply that by 2 in order to get 30.
For the second circle, you are given the diameter. Divide that by 2 to get 273.
For the third circle, you are given the radius. Multiply that by 2 in order to get 248.
Explain how u got the answer
Answer:
rectangle = 2(50) +2(70) + 2(35) = 310
square = 2(32) + 2(12) + 2(24) = 136
Add
136 + 310 = 446 cm^2
SA = 446 cm^2

Answer:
80
Step-by-step explanation:
x + (2x-60) = 180
combine like terms
3x - 60 =180
add 60 to both sides
3x = 240
divide both sides by 3
x = 80
plug it back in to check
80 + (2(80) - 60 = 180
80 + (160 -60) = 180
80 + (100) = 180
180 = 180

From the figure below, Prove that segment JP is parallel to segment LM.
1. Slope of JP
(Write answer as a fraction. Ex 5/6. No spaces)
2. Slope of LM
(Write answer as a fraction. Ex 5/6. No spaces)
3. The two segments are Parallel or Perpendicular?
(spell out the correct
answer. No caps needed)
Answer:
1. Slope of JP is 2/3
2. Slope of LM is 2/3
3. The two segments are Parallel.
Step-by-step explanation:
1. Slope is easy to find out if you have a graph. Rise/Run is how I remember it. The only thing you have to do is count. If you count from P to J Down 2 unites, and left 3 units you get your answer.
2. Slope LM is the exact same as Slope PJ because they are parallel.
3They are parallel because they both have the same slope.
Which statement best explains conditional probability and independence?
When two separate events, A and B, are independent,
P(A and B) P(A).P(B)
P(BA)
P(B). This means that the
P(A)
P(A)
occurrence of event B first did not affect the probability of event A occurring next.
When two separate events, A and B, are independent,
P(A and B) P(A).P(B)
P(BA)
- P(B) This means that the
P(A)
P(A)
occurrence of event B first affected the probability of event A occurring next.
When two separate events, A and B, are independent,
P(A and B) P(A.P(B)
P(BA)
P(B)
P(A)
This means that the
PA
occurrence of event A first did not affect the probability of event B occurring next.
When two separate events, A and B are independent,
P(A and B) P(A).P(B)
P(BA)
P(B)
P(A)
P(A)
This means that the
Answer:
The answer of the question would be: C)
Step-by-step explanation:
When two separate events, A and B, are independent, P(A|B)=P(B). This means that the probability of event B occurring first has no effect on the probability of event A occurring next. Because of the evident independence.
