Step-by-step explanation:
A car travels at 180.0 km/h for 2.8 hours, at 65.0 km/h for the next 3.5 hours, and finally at 100.0 km/h for 2.0 hours. What is the car's average velocity for the entire journey?
Answer:
v = ~122.23 m/s
Step-by-step explanation:
180(2.8) + 65(3.5) + 200 = 931.5
931.5/(2.8 + 3.5 + 2) = 122.2289 ≈ 122.23 = va

Answer:
(-18,9)
Step-by-step explanation (work shown in picture attached):
1) The first step in solving by substitution is to isolate the y-term in one of the equations if it is not already isolated. Isolate y in the first equation by dividing both sides by -2. This leaves us with the equation [tex]y = \frac{-x}{2}[/tex]
2) Now, substitute [tex]\frac{-x}{2}[/tex] for the y in the second equation. Simplify and isolate x. (You can multiply everything by -2 to get rid of the fraction.) This leaves us with x = -18.
3) We've found the x-value of the solution, -18. Now, substitute -18 for x back into one of the original equations (I chose the first one because it was simple) and isolate y. This gives us y = 9. Thus, in point form, the answer is (-18,9).

Answer:
95 cm^2
Step-by-step explanation:
perimeter(p)=39cm
L=3x-1
B=2x+3
Now,
p=2(l+b)
39=2(3x-1+2x+3)
39=6x-2+4x+6
39=10x+4
39-4=10x
x=35/10
x=3.5
Putting the value of x
L=3x-1; =3×3.5-1; =10.5-1; =9.5cm
B =2x+3; =2×3.5+3; =7+3; =10cm
Again,
A= L×B
=9.5×10
=95cm^2
What is the solution to ther equation 2(x-4)squared=50
Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4

The length of AB is 5 units. What is the length of the image of the line segment after a dilation with a scale factor of 5/2 Enter your answer in simplest form in the box.
Answer:
12 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Put 5 in fraction form ( [tex]\frac{5}{1}[/tex] ) and multiply it by [tex]\frac{5}{2}[/tex]
[tex]\frac{5}{1}[/tex]×[tex]\frac{5}{2}[/tex] = [tex]\frac{25}{2}[/tex] now simplify to 12 [tex]\frac{1}{2}[/tex]
A bird feeder is in the shape of a cylinder. It has a volume of about 100 cubic inches. It has a radius of 2 inches. What is the approximate height of the bird feeder? Use 314 for pi.
Answer:
8 in approx
Step-by-step explanation:
Given data
volume = 100 cubic inches
radius= 2 inches
The expression for the volume of a cylinder is given as
v=πr^2h
substitute
100= 3.14*2^2h
100= 12.56h
h= 100/12.56
h=7.9 in
Hence the height is 8in approx

PLEASE GEOMETRY HELP WILL MARK BRAINLIEST!!!
Answer:
Step-by-step explanation:
71+42+BAD=180
BAD=67
Answer:
m<BAD = 67
Step-by-step explanation:
The given figure is a parallelogram. Consecutive angles in a parallelogram are supplementary, meaning that their angle measures sum up to 180 degrees. Using this, one can say,
m<D + m<A = 180
Substitute,
m<ADB + m<BDC + m<A = 180
71 + 42 + m<A = 180
113 + m<A = 180
Inverse operations,
113 + m<A = 180
-113 -113
m<A = 67

1. {MCC.7.G.6) The area of the base of an 8-inch-tall cylinder is 36T
square inches. What is the volume of this cylinder (rounded to the
nearest whole cubic inch)?
Answer:
[tex]Volume = 144in^3[/tex]
Step-by-step explanation:
Given
[tex]Base\ Area = 36in^2[/tex]
[tex]Height =8[/tex]
Shape: Cone
Required
Determine the volume
Volume is calculated using:
[tex]Volume = \frac{1}{3}\pi r^2h[/tex]
Where
[tex]Base\ Area = \pi r^2 = 36[/tex]
[tex]Height = h = 8[/tex]
So:
[tex]Volume = \frac{1}{3} * 36 * 8[/tex]
[tex]Volume = 144in^3[/tex]
Throughout Lewis Carroll's book, Alice's Adventures in Wonderland, Alice's size changes. Her normal height is about 50 inches tall. She comes across a door, about 15 inches high, that leads to a garden. After drinking a potion, Alice's height changes to 10 inches so she can visit the garden. How tall would the door have been in Alice's normal world? Justify your answer and provide mathematical evidence.
Answer:
The answer is 75 inches.
Step-by-step explanation:
If Alice is 10 inches, she is 2/3 as tall as the door. At her regular height, to be 2/3 as tall as the door the door would have to be 75 inches high.

Step-by-step explanation:
Please give me the correct answer.Only answer if you're very good at math.Please don't put a link to a website.
Answer:
there are infinitely many solutions
LEFT SIDE/ LEFT EQUATION: if you multiply 1 and (b + 14) together, the result becomes the numerator of the fraction (with 2 being the denominator).
Once you do that, you will notice that both sides/both equations are exactly the same.
Thus, if you put in ANY number for variable b, the solution of both sides/both equations will always be the same and work.
The answer is: "There are infinetly many solutions"

To track the reptile population around a lake, researchers marked 36 turtles. A few weeks later, they counted 400 turtles, of which 20 were marked. To the nearest whole number, what is the best estimate for the turtle population?
Answer: 720
Step-by-step explanation:
From the question, we are informed that cthe researches counted 400 turtles, of which 20 were marked. This implies that 20/400 = 1/20 were marked.
If the researchers wanted to track the reptile population around a lake, and the researchers marked 36 turtles, the estimate of the total population will then be:
1/20 × x = 36
x/20 = 36
x = 20 × 36
x = 720
The turtle population is 720
Factor: 36x^2-64

A stadium is divided into 4 sections. Each section is laid out in rows.
Section
Number of Rows
A: 42
b:50
c:36
D:16
There are 8 seats in each row of Section C. Which of the following equations can you use to find the number of seats in Section C? Select all
that apply.
S = 8 + 36
S = 36 + 36 + 36 + 36 + 36 + 36 + 36 + 36
S = 42 + 50 + 36 + 16
S = 8 x 36
S = 8 x 42
Part B
How many seats are in Section C? Enter your answer in the box.
Answer:
Both S=8x36 and S=36+36+36+36+36+36+36+36 apply
There are 288 seats in section C

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
122° is an exterior angle to both triangles , then
∠ 1 + 75° = 122° ( subtract 75° from both sides )
∠ 1 = 47°
and
∠ 2 + 88° = 122° ( subtract 88° from both sides )
∠ 2 = 34°
