Answer:
0.82 m/s^2
Step-by-step explanation:
Given data
initial velocity=20m/s
Final velocity= 30m/s
Time = 12.2s
Applying the formula
a= v-u/t
a= 30-20/12.2
a= 10/12.2
a= 0.819
a=0.82 m/s^2

Two angles in a triangle measure 102° and 670. What is the measure of the third angle?
0 110
0789
1139
O 169°
Step-by-step explanation:
step 1. wow! 670° I think you mean 67°
step 2. the 3 internal angles of a triangle add up to 180°. let x be the third angle
step 3. x + 102 + 67 = 180
step 4. x + 169 = 180
step 5. x = 11°.

Lily wants to ride her bicycle 43 miles this week. She has already ridden 16 miles. If she rides for 6 more days, what is the average number of miles she would have to ride each day to meet her goal?
Answer:
43-16=miles left to go. divide that by the 6 days left.
43-16= 27 miles.
27÷6= 4.5 miles per day
Answer:
4 1/2 miles
Step-by-step explanation:
43 - 16 = 27 miles remaining
27/6 = 4 3/6 or 4 1/2
What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13
Have a nice day! :D

Answer:
x = 2.57
Step-by-step explanation:
6/x = 7/3
7x = 18
x = 2.57
check:
if x = 2.57
then:
2.57/6 = 3/7
0.4283 = 0.4283
that checks as correct
Sharlene wraps a cylindrical package that has a height of 15 inches and
a radius of 3 inches. What is the package’s surface area?
Answer:
339.3 cubic inches
Step-by-step explanation:
SA (cyl) = 2πr² + 2πrh
SA = 2(3²)π + 2(3)(15)π
SA = 18π + 90π
SA = 108π
SA ≈ 339.3 in³

Santosh spent $200, before tax, on a DVD player and DVDs. The player cost $120, new DVDs cost $15 and used DVDs cost $5. Santosh purchased the same number of new and uses DVDs. Write and solve an equation to find the number of each type of DVD Santosh purchased.
Answer:
Santosh purchased 4 new and 4 used DVDs.
Step-by-step explanation:
From the information given, as you know that Santosh spent $200 and that the DVD player cost $120, you can say that the new and used DVDs cost $80, which can be expressed as:
15x+5y=80, where:
x refers to the number of new DVDs
y refers to the number of used DVDs
Now, as the statement indicates that Santosh purchased the same number of new and used DVDs, this means that x is equal to y and you can replace y with x and solve for x:
15x+5x=80
20x=80
x=80/20
x=4
According to this, the answer is that Santosh purchased 4 new and 4 used DVDs.

Which ordered pair is a solution to the graphed inequality?
Given:
The graph of a system of inequalities.
To find:
The ordered pair which is a solution to the graphed inequality.
Solution:
The boundary lines are:
[tex]x-2y=4[/tex]
[tex]2x-y=4[/tex]
From the given graph it is clear that only point (3,1) lies in the shaded region.
Points (2,-1) and (4,0) lie on the boundary line [tex]x-2y=4[/tex] but the boundary line is dotted. It means the points on the line are not in the solution set.
point (0,-1) does not belong to the shaded region.
Therefore, the correct option is A.

The length of a rectangle is 7 centimeters greater than the width.
The perimeter is 54 centimeters. Find the length and width.
Answer:
length = 17cm, width = 10cm
Step-by-step explanation:
2L + 2w = 54
L = w + 7
Substitute:
2(w + 7) + 2w = 54
2w + 14 + 2w = 54
4w = 40
w = 10
L = 10 + 7 = 17

help me with this please
Answer:
Step-by-step explanation:
if 45+47=t and t=45+47 t would equal 92 in both
45+47<t than t<45+47
so basically its saying 92<t (92is less than t) and t<92 (t is greater than 92)
he is not right. When you have an equation like that the answer is 92. Its not going to be greater or less than 92. It is 92. It should be t=92
hope that masks some kind of sense. It after 1am here so I apologize if it doesn't sound right...
