Answer:
260 miles
Step-by-step explanation:
Given that:
Distance covered in 7 hours = 455 miles
Number of miles train will travel in 4 hours
Average travel speed per hour :
Distance traveled / time taken
455 miles / 7 hours
= 65 miles per hour
Number of miles traveled in 4 hours :
Average Speed per hour * time
(65 * 4) = 260 miles
In a population of spiders, there is a protein that is coded in the
DNA to make venom. In a particular spider, there was a protein
variation due to a change in the genetic code. This protein
variation caused the spider's venom to be stronger to kill its prey.
This genetic variation was passed down to offspring and was
favored due to the amount of time shortened to eat its prey.
What will likely happen to this population of spiders?
eventually all of the offspring will have the genetic variation
Step-by-step explanation:
the variation was passed down to its offspring, and was favored, so it is now just part of its genetics, meaning all of the offspring from the original spiders offspring, will also have the genetic variation. hope this helps :)

The game is also sold at the factory outlet for a net profit of $10.99 on each game. If 500 games are sold by the outlet, many more would have to be sold by the retailer in order for the profit to be about equal
Answer:
The number of games that need to be sold to the retailer in order for the profit to be about equal is approximately 555 games
Step-by-step explanation:
The given parameters are;
The net profit at which each game is sold to a retailer = $9.90
The net profit at which each game is sold at the factory outlet = $10.99
The number of units sold by the outlet = 500
The amount in profit from selling at the factory outlet = 500 × $10.99 = $5,495.00
The number of games that need to be sold to the retailer in order for the profit to be about equal is given as follows;
Let "x" represent the number of games that need to be sold to the retailer in order for the profit to be about equal
Therefore, we have;
x × $9.90/game = $5,495.00
x = $5,495.00/($9.90/game) = 555.[tex]\overline {05}[/tex] games ≈ 555 games
Therefore, the number of games that need to be sold to the retailer in order for the profit to be about equal = x ≈ 555 games.

answers for both boxes please
Answer:
x = -5 y = -3
Step-by-step explanation:
-3x + 2y = 9
multiply the 2nd equation by 3 to set it up for elimination
3(x - 3y)= 3(4)
3x-9y = 12
so now combine both to add
-3x + 2y = 9
3x - 9y = 12
Adding both gives you
-7y = 21
divide both by -7 and you get
y = -3
and you substitute y back into equation to get x
x - 3 (-3) = 4 gives you
x + 9 = 4
x = 4 - 9
x = -5
Find the measure of the missing angle.
Answer:
23º = x
Step-by-step explanation:
One straight line is ALWAYS 180º
(called a linear pair)
So your equation is
157º + x = 180
subtract x on both sides
and you get
23º
That is a question about angles.
The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.
So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:
[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]
Therefore, the missing angle is 23°.

Make b the subject of the formula a = vb + 6
Answer:
[tex]b = \frac{a -6}{v}[/tex]
Step-by-step explanation:
Given
[tex]a = vb + 6[/tex]
Required
Make b the subject
[tex]a = vb + 6[/tex]
Subtract 6 from both sides
[tex]a -6= vb + 6-6[/tex]
[tex]a -6= vb[/tex]
Divide both sides by v
[tex]\frac{a -6}{v}= \frac{vb}{v}[/tex]
[tex]\frac{a -6}{v}= b[/tex]
Reorder
[tex]b = \frac{a -6}{v}[/tex]

Mark and Jen me at the beach yesterday July 31. Might go to the beach every third day in Django ceviche before three. How many times will they be at the beach on the same day over the next 30 days?
Answer:
The number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.
Step-by-step explanation:
Every third day implies that they both go the beach and then have a two day break, and then go the beach on the day after.
Put simply, every third day implies one day in three days.
Based on the above, the number times both Mark and Jen will be at the beach on the same day over the next 30 days can be calculated by dividing 30 by 3 as follows:
Number times both Mark and Jen will be at the beach = 30 / 3 = 10
Therefore, the number times both Mark and Jen will be at the beach on the same day over the next 30 days is 10 times.

a first number plus twice a second number is 4. twice the first number plus the second number totals 26. find the numbers
Answer:
a = 16
b = -6
Step-by-step explanation:
a + 2b = 4
2a + b = 26
2a + 4b = 8
2a + b = 26
3b = -18
b = -6
a + 2(-6) = 4

Rahan is on holiday in the USA. He has $200 to spend on clothes.
Rehan buys. 1 pair of trainers costing $60. 3T. shirts costing $25 each.
He also wants to buy a jacket costing $80
Has Rehan got enough money to buy the jacket
Rahan doesn't have enough money that'll be required in buying the jacket.
Total Amount with Rahan = $200
Total amount of expenses = (1 × $60) + (3 × $25) + $80
= $60 + $75 + 80.
= $215
In this case, since Rahan has $200, then he doesn't have enough money that he'll use in buying the jacket.
