Hey there! I'm happy to help!
Let's call this number n. We can create the following equation.
(n+45)/2=5
Let's solve. We multiply both sides by 2.
n+45=10
We subtract 45 from both sides.
n=-35.
Have a wonderful day! :D
Answer:
n=-35

an air plane is travaling at 400 miles per hour. which equation can be used to find the total distance the plane will travel in h hours?
Answer:
I think 400+24=424
Step-by-step explanation: i think its that equation because there are 24 hours in a day so if you put that with 400 you'll get 424

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 90
miles per hour. The westbound train travels at 80 miles per hour. How long will it take for the two trains to be 408 miles
apart?
Do not do any rounding.
x = # of hours
80x + 90x = 408
Combine like terms.
170x = 408
Divide both sides by 408
x = 2.4 hours
It will take the trains 2.4 hours to be 408 miles apart.
The two trains will travel their 408-mile distance in around 2.4 hours.
To determine the time it will take for the two trains to be 408 miles apart, we can use the concept of relative motion.
Since the two trains are moving away from each other in opposite directions,
their speeds are added to calculate the rate at which the distance between them is increasing.
Let's consider the time it takes for the trains to be 408 miles apart:
Distance = Rate × Time
For the eastbound train:
Distance = 90 miles/hour × Time
For the westbound train:
Distance = 80 miles/hour × Time
Since the trains are moving away from each other, their distances traveled add up to the total distance between them:
90 miles/hour × Time + 80 miles/hour × Time = 408 miles
Combining like terms:
170 miles/hour × Time = 408 miles
To solve for Time, isolate it by dividing both sides of the equation by 170 miles/hour:
Time = 408 miles / 170 miles/hour
Now we can calculate the time:
Time = 2.4 hours
Therefore, it will take approximately 2.4 hours for the two trains to be 408 miles apart.

Rock climbing. I am out rock climbing, and the rock face has 4 easy, 7 challenging, and 3 extreme routes to get to the top. The routes are poorly marked, so I just choose one at random, with all routes equally likely. What is the probability that I do not choose an extreme route
Answer:
0.7857
Step-by-step explanation:
Given the following :
Number of Easy faces = 4
Number of challenging faces = 7
Number of extreme faces = 3
Total number of faces or route = (4 + 7 + 3) = 14
If one route is chosen at random, the probability of not choosing an extreme route will be :
Probability = (required outcome / Total possible outcomes)
P(not choosing an extreme route) = 1 - P(choosing an extreme route)
P(choosing an extreme route) = 3 / 14 = 0. 2143
Hence,
P(not choosing an extreme route) = 1 - 0.2143
= 0.7857

how to calculate total ouput
Answer:
measure aggregate output by adding up the total expenditures by households. Then, if we assume that one person's spending is another person's income, an equivalent measure of the value of total output would be the total income reported by individuals.

There are 4,200 butterflies. 800 are orange, 200, purple, 400 are yellow and the rest are blue. What fraction of the butterflies are blue ?
Answer:
2/3 is the answer
Answer:
2/3
Step-by-step explanation:
First you add all the colors. Then you subtract that number from 4200 to get the total number of blue buterfiles. After that, you put the total number of blue butterflies in the numerator and the 4200 would go in the denominator. Then you reduce until u get the final fraction.

What is the length of the given segments EF and GH?
Answer:
[tex] EF = 5 [/tex]
[tex] GH = 5 [/tex]
Step-by-step explanation:
Length of EFis the distance between E(-4, -3) and F (-1, 1).
[tex] EF = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]
Let,
[tex] E(-4, -3) = (x_1, y_1) [/tex]
[tex] F(-1, 1) = (x_2, y_2) [/tex]
[tex] EF = \sqrt{(-1 -(-4))^2 + (1 -(-3))^2} [/tex]
[tex] EF = \sqrt{(3)^2 + (4)^2} [/tex]
[tex] EF = \sqrt{9 + 16} = \sqrt{25} [/tex]
[tex] EF = 5 [/tex]
Distance between G(-2, -3) and H(3, -3)

[tex] H(3, -3) = (x_2, y_2) [/tex]
[tex] GH = \sqrt{(3 -(-2))^2 + (-3 -(-3))^2} [/tex]
[tex] GH = \sqrt{(5)^2 + (0)^2} [/tex]
[tex] GH = \sqrt{25 + 0} = \sqrt{25} [/tex]

You are baking and run out of an important ingredient. Rather than fire up the car, you decide to use a bicycle. The store is 1/2 mile away. Assume your car gets 30 miles to the gallon. If every driver on the planet made a similar decision once per week for a year, approximately how much gas would be saved for that year
Answer:
approximately 1.213 billion gallons of fuel will be saved per year.
Step-by-step explanation:
Distance to the store = 1/2 mile
If my car gets 30 miles to one gallons, then for 1/2 mile my car will use
1/2 ÷ 30 = 1/2 x 1/30 = 1/60 gallons
Statistics puts the number of cars users on Earth to be about 1.4 billion = 1.4 x 10^9 cars
If every driver makes this decision once a week for a year, that will be 52 times a year since there are 52 week in a year.
Total gas that will be saved in one week = 1/60 x 1.4 x 10^9 = 23333333.3 gallons
In a year that will be = 23333333.3 gallons x 52 = 1.213 x 10^9 gallons
that is approximately 1.213 billion gallons of fuel saved per year

Write the sentence as an inequality. A number x is no less than –8.
x ≥ -8
Answer choice D is correct
x ≥ -8 represents the given inequality. Option C is correct.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here.
A number x in no less than -8,
Implies that the number x must be equal to -8 or more,
Applying the greater equal to sign(≥) between the x and -8
x ≥ -8
Thus, x ≥ -8 represents the given inequality. Option C is correct.

What is the value of x in the equation LaTeX: \frac{3}{2}\left(4x-2\right)-3x=5-\left(x+2\right) 3 2 ( 4 x − 2 ) − 3 x = 5 − ( x + 2 ) ?
Answer:
3/2
Step-by-step explanation:
Given the equation 3/2(4x-2)-3x = 5-(x+2)
Open the parenthesis
3/2(4x) - 3/2(2) -3x = 5-x-2
6x-3-3x = 3-x
3x-3 = 3-x
Collect like terms
3x+x = 3+3
4x = 6
Divide both sides by
4x/4 = 6/4
x = 3/2
Hence the value of x is 3/2
1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is the interst rate and t is the time. Sometimes it can be tricky to know what value to use when calculating t. A. What would you plug into the simple interest formula for t if you were given a time of 3 years? B. What would you plug into the simple interest formula for t if you were given a time of 4 months? C. What would you plug into the simple interest formula for t if you were given a time of 45 days?
Step-by-step explanation:
To determine simple interest, we use the formula
[tex]I=Prt[/tex]
where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years
When the times is 3 years , then we plug in 3 for 't' directly
[tex]I=Pr(3)\\[/tex]
we know that 1 year = 12 months
Suppose, the time is given in months then we divide time 't' by 12
When the times is 4 months , then we plug in 4 for 't' and divide by 12
[tex]I=\frac{Pr(4)}{12}[/tex]
we know that 1 year = 365 days
Suppose, the time is given in days then we divide time 't' by 365
When the times is 45 days , then we plug in 45 for 't' and divide by 365
[tex]I=\frac{Pr(45)}{365}[/tex]

A regular polygon of n sides has its sum of interior
angles as 900° What is n?

D. 8
Answer:
C. 7Step-by-step explanation:
n is the number of sides of the polygon
[tex](n - 2) \times 180 = 900[/tex]
Divide both sides of the equation by 180
[tex] \frac{(n - 2) \times 180}{180} = \frac{900}{180} \\ n - 2 = 5 \\ n = 5 + 2 \\ n = 7[/tex]
