Answer:
The answer is "2.2 h"
Step-by-step explanation:
Speed of Train B:
[tex]= \frac{3}{2} \times 70 \ mph \\\\= 105 \ mph[/tex]
Train B is then moving on:
[tex]= \frac{200 \ miles}{ 105 \ mph} \\\\= 1.905 \ h\\[/tex]
Then it takes Train A to the left:
[tex]\to 1.905\ h + 20 \ min \\\\= 1.905 \ h +0.333 \ h \\\\= 2.238 \ h[/tex]
To get train B to the reference point of train A = 2.2 h
Help it’s due tomorrow I’ll mark you as the brainless but please help
Answer:
The slope of a line is
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Get 2 points off each line
(x1, y1)
(x2, y2)
And sub them into the formula.
The y intercept is where the line cuts the y axis (the vertical line)
From what I can make out the y intercept for the first part in question 12 is (0,-2) and for the third part is (0,0) but I can't see the second one.
It might help if you took a clearer photograph I'm so sorry but I can't really see it.
sam can make 18 burritos in 8 min write the ratio that compares the time to the number of burritos simplify if possible
Answer:
Ratio time to the number of burritos = 4:9
Step-by-step explanation:
Given:
Number of burritos make = 18
Total time taken = 8 min
Find:
Ratio time to the number of burritos
Computation:
Ratio time to the number of burritos = Total time taken / Number of burritos make
Ratio time to the number of burritos = 8 / 18
Ratio time to the number of burritos = 4 / 9
Ratio time to the number of burritos = 4:9
You want to go to the movies with your friends and your parents offer to pay for everyone.
If each movie ticket is $13.50 and you plan on splitting a giant popcorn and drink that cost
$19.95 total, what is the maximum number of tickets you can buy if your parents give you
$75?
Answer:
4 tickets
Step-by-step explanation:
1. make an equation representing the situation. x is the number of how many tickets you buy
13.5x + 19.95 = 75
2. subtract 19.95 from both sides
13.5x = 55.05
3. divide by 13.5 on both sides
x = 4.08
now, you can't buy 0.08 of a ticket, so you have to round to the nearest whole number, which in this case is 4.
Answer:
4 tickets
Step-by-step explanation:.
13.5x + 19.95 = 75
13.5x = 55.05
x = 4.08
Now, you have to round to the nearest whole number, which in this case is 4.

How would I find the answer to this
Answer:
answer is 108
Step-by-step explanation:
You would divide 28 by 7 which is 4 so the bigger triangle is 4 times the size of the smaller rectangle. in order to find the perimeter you would multiply each side of the smaller triangle by 4 and add up all the sums. except the one you were given so 28+(12times4)+(8times 4)+108
hope this helps you out :)
Write an equation in point-slope form of the line that passes through (2,7) and has the slope m=4
Answer: y-7=4(x-2)
Step-by-step explanation:
Point-slope form is y-y₁=m(x-x₁). Since we are given the point and slope, we can directly plug them in.
y-7=4(x-2)
Now, we know that y-7=4(x-2) is the equation.
Solve for x.
4x +15 > 23
Answer: x > 2
Step-by-step explanation:
First, you need to isolate the variable by subtracting each side by 15.
4x + 15 > 23
-15 -15
= 4x > 8
To get the value for the variable, divide each side by 4.
4x/4 = x 8/2 = 2
x>2
Answer:
Step-by-step explanation:
4x + 15 > 23
4x > 8
x > 2

From 2010 to 2011, the population of Queens increased by 16,075. Brooklyn’s population increased by
11,870 more than the population increase of Queens.
a. Estimate the total combined population increase of Queens and Brooklyn from 2010 to 2011.
(Round the addends to estimate.)
b. Find the actual total combined population increase of Queens and Brooklyn from 2010 to 2011.
c. Assess the reasonableness of your answer in (b). Use your estimate from (a) to explain.
Answer:
The population of Queens increased by 16,075.
The population of Brooklyn increased by 11,870 more than that, then the population of Brooklyn increased by:
16,075 + 11,870 = 27,945
a) The total combined population increase is (when we round the addens)
I will round in the thousands place.
To do it, we must look at the hundreds place, if the decimal is 5 or larger, we round up.
If the decimal is smaller than 5, we round down.
16,074 ≈ 16,000
27,945 ≈ 28,000
16,000 + 28,000 = 44,000
b) Now using the actual numbers:
16,075 + 27,945 = 44,020.
c) now let's compare our two results:
Let's see the difference between them
a = 44,000
b = 44,020
a - b = 44,000 - 44,020 = -20.
This means that our estimated from (a) is 20 units smaller than the actual number.
But this is insignificant compared with the 44,020.
Why?
we can calculate the relative error as:
100%*(estimate value - real value)/(real value)
100%*(-20/44,020) = -0.05%
So the error is on the -0.05%, which is despreciable.
From this, we can conclude that the estimation in (a) is a really good estimation.

-5+2a=4a-4-3a help plz and thank you
Answer:
a=1
Step-by-step explanation:
To make this easier, combine like terms first.
-5+2a=4a-4-3a
-5+2a=a-4
Then, add 5 on both sides.
-5+2a=a-4
+5 +5
2a=a+1
Now, subtract a on both sides.
2a=a+1
-a -a
a=1

PLS HELP I CANT DO THIS
Answer:
The answer would be 5
Step-by-step explanation:
2x2x2=8
Lets use the other 5 since it is already given to us.
so 8x5=40
no we must get 200 with the 40
so 200/40=5
Thus the missing number will be 5

Answer:
D - 43°
E - 43°
Step-by-step explanation:
In squares all sides are equal, which means one of these angles are given and neither one leave the square, so 43° would be the degree of each angle inside this square.

Consider function h.
What is the approximate range of function h?
(blank) (blank) y (blank) (blank)
Options: 3, 6, -2, -∞, 12, ∞
<, ≤
Answer:
Range : (-∞, 12] Or -∞ < x ≤ 12.
Step-by-step explanation:
Domain of function is represented by the x-values (input values) of the function given in the graph.
Similarly, Range of the function is define by the y-values (output values) on the graph of a function.
Since y-values on the graph are between 12 and negative infinity (Including 12),
Therefore, range of the function will be (-∞, 12] or -∞ < x ≤ 12
Answer:
-∞ < y ≤ 12
