Step-by-step explanation:
This assumes you were given the mass of mars to be [tex]6.39*10^2^3kg[/tex] the mass of the sun to be [tex]1.99*10^3^0kg[/tex] and the gravitational force between the two to be [tex]3.72*10^3^5N[/tex].
I used the formula: (G is the gravitational constant [tex]6.67*10^-^1^1[/tex])
[tex]F=G\frac{m_1m_2}{r}[/tex]
and solved for r
[tex]3.72*10^3^5=6.67*10^-^1^1\frac{6.39*10^2^3(1.99*10^3^0)}{r}[/tex]
[tex]r=\frac{8.48*10^4^3}{3.72*10^3^5}[/tex]
[tex]r=2.28*10^8km[/tex]

acer
Answer:
Total percent: 3.7%
Step-by-step explanation:
(2000 x 0.01) + (4240 x 0.05) = $232
X/100 = 232/6240
= 23200/6240 = 3.7%

Susie has read 52 pages of an 80- page book. What is the percentage of the pages that susie has not read?
Answer:
35%
Step-by-step explanation:
52/80=0.65
0.65x100=65
65% is the percent that she has read.
100%-65%= 35%
She has not read 35% of the pages.
Answer:
She hasn't read 35% of the book
Step-by-step explanation:
1st way: Since 80 pages represent 100%
52 pages represent 100 * 52 / 80 = 65% pages read
100 - 65 = 35 pages page not read.
2nd way: 80 - 52 = 28 pages not read
28 pages represent 100 * 28 / 80 = 35% pages not read
1.2) Raflte tickets cost $6 for 5 tickets
How many tickets can you get for $90
-5x+35=40
what are the steps?
Answer:
Step-by-step explanation:
-5x + 35 = 40
Subract 35 from both sides -5x + 35 - 35 = 40 - 35 = (-5x = 5)
Divide -5 from both sides -5x / -5 = 5 / -5 =
x = -1
Answer:
x= -1
Step-by-step explanation:
First subtract 35 from both sides to get -5x by itself:
-5x+35=40
-35 -35
-5x=5
Then divide by -5:
[tex]\frac{-5x}{-5}[/tex] = [tex]\frac{5}{-5}[/tex]
x=-1

Answer:
He runs 1 1/2 miles per practice.
Explanation:
First, you need to find the slope. This can be done by finding two points on the graph. Then you count the distance between the two y-values, and then the distance between the two x-values. Then you create a fraction with the numerator being the distance of y-values and the denominator the distance of x-values. For example, I chose the points (4,8) and (2,5) The distance between those two is 3/2. This simplifies to 1 1/2. Therefore, the slope of the graph is 1 1/2.
Hope this helped and have a great day,

Travel agents collected data from recent travelers about their modes of transportation for their vacations, They found that 37% traveled by airplane, 8% traveled by train, and 7% traveled by airplane and train. Let A be the event that the mode of travel was airplane and let T be the event that the mode of travel was train.
Using Venn probabilities, it is found that the probability is [tex]P(A \cap T^{c}) = 0.3[/tex]
In this problem, the events are:
Event A: Traveled by airplane.Event T: Traveled by train.Event [tex]T^{c}[/tex]: Did not travel by train.The desired probability is:
[tex]P(A \cap T^{c}) = P(A) + P(T^{c}) - P(A \cup T^{c})[/tex]
The probabilities are:
37% traveled by airplane, hence [tex]P(A) = 0.37[/tex]8% traveled by train, hence [tex]P(T^c) = 1 - 0.08 = 0.92[/tex]37% traveled by airplane, 62%(100 - [37 + 8 - 7]) did not travel, hence [tex]P(A \cup T^c) = 0.37 + 0.62 = 0.99[/tex]Then:
[tex]P(A \cap T^{c}) = P(A) + P(T^{c}) - P(A \cup T^{c})[/tex]
[tex]P(A \cap T^{c}) = 0.37 + 0.92 - 0.99[/tex]
[tex]P(A \cap T^{c}) = 0.3[/tex]

Answer:
Down 3 unitsStep-by-step explanation:
Given functions:
f(x) = ∛x and g(x) = ∛x - 3The g(x) is a translation of f(x) down 3 units, as g(x) = f(x) + b is a vertical shift b units (up if b > 0, down if b < 0)

What is the 5th term of the linear sequence? 1,7,13,19,25,...
Answer : 31
Explanation : Every numbers have a gap of 6 as you can see:
1 + 6 = 7
7 + 6 = 13
13 + 6 = 19
19 + 6 = 25
So,

Answer: No, they don't have enough money.
==========================================================
Explanation:
Let's find the area of the shape given. It's composed of two rectangles.
larger rectangle area = 8*9 = 72 sq meterssmaller rectangle area = 6*7 = 42 sq metersThe two rectangle areas add to 72+42 = 114 sq meters. This is the total floor area.
---------------------
Let x be the number of tins of polish the caretaker buys.
One tin covers 12 m^2 of floor area. Buying x of them covers 12x square meters of space. We need to cover 114 square meters.
Solving 12x = 114 leads to x = 9.5 when you divide both sides by 12.
Since the caretake cannot buy half a tin, we must round up to the nearest whole number. This means s/he must buy 10 containers of polish.
---------------------
Each bottle of polish costs £19
Ten of them cost 10*19 = 190 pounds. This is before the discount.
If you save 30%, then you save 0.30*190 = 57 pounds and the final price is 190-57 = 133 pounds.
Or put another way: if you save 30%, then you pay the remaining 70% and that final price is 0.70*190 = 133 pounds.
This final price is 3 more pounds than what the caretaker has, so they don't have enough money.

4. How long would it take sound waves traveling through air that is 68°F to
travel 1,372 meters? Use an equation to solve the problem.
Answer:
2.7 seconds
Step-by-step explanation:
[] Temp of air: 68°F -> 20°C
[] Velocity of sound in air:
[tex]v=331.3\sqrt{1+\frac{T}{273.15} }[/tex]
[tex]v=331.3\sqrt{1+\frac{68}{273.15} }[/tex]
v ≈ 370.25 m/s
[] Last,
t = [tex]\frac{d}{v}[/tex]
t = [tex]\frac{1,372}{370.25}[/tex]
t ≈ 3.7056 ≈ 2.7 seconds

Answer
your equation in part c is wrong
Step-by-step explanation:
part c

11=2m+c-----------(1)
15=3m+c----------(2)
(2)-(1)
15-11=(3m+c)-(2m+c)
4=3m-2m+c-c
m=4
substitute in (1)
2m+c=11
2*4+c=11
8+c=11
c=3
so equation should be y=4x+3
