The asteroid are separated by 383,000 km.
The asteroid moves 99,500 km toward the planet.
Let F = how far does the asteroid need to travel before reaching the planet.
F = 383,000 km - 99,0m500 km
F = 283,500 km

In a diagram of a landscape plan, the scale is 1 cm = 10 ft. In the
diagram, the trees are 4.2 cm apart. How far apart should the actual trees
be planted?
Answer:
42 ft
Step-by-step explanation:
4.2/1=4.2
4.2*10=42 ft
PLS GIVE BRAINLIEST
Answer:
42
Step-by-step explanation:
1 cm=10ft on the diagram
so the only thing we have to do is multiply.
4.2x10=42 make sure your answer is in FT not CM
so for example
42ft. Units are important XD

The sum of infinity of the series 2/3 – 4/3² + 2/3³ + 4/3⁴ is
Answer:
[tex] \frac{3}{4} - \frac{2}{4} = \frac{1}{4} [/tex]
Answer:
7/20Step-by-step explanation:
It seems there are two patterns in the series:
2/3, 2/3³, ... with a₁ = 2/3 and r = 1/9- 4/3², 4/3⁴, ... with a₁ = -4/9 and r = -1/9Using sum of infinity of the geometric series formula:
S∞ = a₁/(1 - r)Applying this to both patterns:
S₁ = 2/3÷(1 - 1/9) = 2/3 ÷ 8/9 = 2/3×9/8 = 3/4S₂ = -4/9÷(1 - (-1/9)) = -4/9÷10/9 = -4/9×9/10 = - 2/5Sum of the two results:
3/4 + (-2/5) = 5/5*3/4 - 4/4*2/5 =15/20 - 8/20 = 7/20Seats in commercial airplanes are designed so most passengers are comfortably seated. To design an airplane, an engineer at Bombardier Aerospace uses the normally distributed height of Québec adults, which has a mean of 170 cm and a standard deviation of 12 cm
a. The designer will design the seating so 98% of passengers are comfortable. What is the height of someone who is taller than 98% of all other Québec adults?
b. The airplane can hold up to 110 passengers. What is the probability that the average height of passengers is smaller than 100 or larger than 190 cm?
c. If we market this airplane to the American market for which the mean height of adult Americans is 185 cm with a standard deviations of 16 cm, what proportion of American adults would be taller than the height found in (a)? Would this be a problem for Bombardier when it tries to sell the plane to American airline companies?

3 kg of beef costs £51
Max buys 2 kg of beef.
Work out how much Max pays
Find the rate:
51 ÷ 3 = £17
1 kg of beef = £17

Answer:
C.
Step-by-step explanation:
Its C becase, A is not a viable answer because the some of the outputs are not positive. And not B because one input yields 1 output not multiple so its not B. And its not D because as you can see the 'y' side has 2 of the same numbers so its not D. Therefore, the answer is C!

Question 2 options: A consumer advocate group selects a random sample of 205 snack foods and finds that 174 of them contain more fat grams than what is indicated in the snack's nutritional information. Create a 90% confidence interval for the population proportion for snack foods that contain more fat grams that what is indicated in the snack's nutritional information.
Answer:
156 snack foods.
Step-by-step explanation:
205 - 174 = 31
To find 90% of 174, multiply 174 by 0.90.
174 x 0.90 = 156
The answer is 156 snack foods.
How do you do this question?
Answer:
-1
Step-by-step explanation:
dy/dt = y² − 1 = (y + 1) (y − 1)
At t = 0, y = 0, and dy/dt = -1. Therefore, y is initially decreasing.
As y decreases, dy/dt increases. When y = -1, dy/dt = 0 and changes signs from negative to positive.
As y increases above -1, dy/dt again becomes negative. So y continues to approach -1 as t approaches infinity.

Given that k-5, k+7, k+55 are three consecutive terms in a geometric sequence, solve for k
Answer:
[tex]k = 9[/tex]
Step-by-step explanation:
Given:
Consecutive Terms: k-5, k+7, k+55
Required:
Determine the value of k
To do this, we make use of the concept of common ratio.
The common ratio (r) of a geometric sequence is:
[tex]r = \frac{T_{n}}{T_{n-1}}[/tex]
In other words:
[tex]r = \frac{T_3}{T_2} = \frac{T_2}{T_1}[/tex]
Where 1, 2 and 3 represents the terms of the progression/sequence
So:
[tex]r = \frac{T_3}{T_2} = \frac{T_2}{T_1}[/tex] becomes
[tex]\frac{k+55}{k+7} = \frac{k+7}{k-5}[/tex]
Cross Multiply:
[tex](k+55)(k-5) = (k+7)(k+7)[/tex]
Open Brackets
[tex]k^2 + 55k - 5k - 275 = k^2 + 7k + 7k + 49[/tex]
[tex]k^2 + 50k- 275 = k^2 + 14k + 49[/tex]
Collect Like Terms
[tex]k^2 - k^2 + 50k-14k = 275 + 49[/tex]
[tex]36k = 324[/tex]
Solve for k
[tex]k = 324/36[/tex]
[tex]k = 9[/tex]

Step-by-step explanation:
The Los Angeles area experiences many earthquakes. In 1994, the Northridge earthquake measured 6.7 on the Richter scale. In 2014, Los Angeles experienced an earthquake that measured 5.1 on the Richter scale. Compare the intensities of the two earthquakes. Use a logarithmic model to solve. Round to the nearest whole number.
Answer:
The intensity of the 1994 earthquake was about 40 times the intensity of the 2014 earthquake.
Step-by-step explanation:
1994 earthquake:
6.7I=logI=106.7
2014 earthquake:
5.1I=logI=105.1
Form a ratio of the intensities.
intensity for 1994intensity for 2014
Substitute in the values and divide by subtracting the exponents to find
106.7105.1101.6≈40.
The intensity of the 1994 Northridge earthquake in the Los Angeles area was about 40 times the intensity of the 2014 earthquake.

Complete the blank with either ∈ or ∉ so that the resulting statement is true. −2__{−6,−3,−5,−1}
Answer:
−2 ∉ {−6,−3,−5,−1}
Step-by-step explanation:
Given
Set = {−6,−3,−5,−1}
Element = -2
Required
The interpretation of the question is to state if -2 is an element of the given set or not
The first thing to do is to check through the set to count the number of occurrence of -2
Looking through Set = {−6,−3,−5,−1}, we have that the occurrence of -2 is 0
This implies that -2 is not an element of the given set and this is represented by the symbol ∉
Hence:
−2 ∉ {−6,−3,−5,−1}
