From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.
Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute
Determining the number of minutes she will have to take in order to reach school,
Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes
Adding this to the initial time,
Final time = 8:25 am + 20.52 minutes
= 8:45 am and 31.2 seconds.
She will reach the school on time even without increasing her speed.

Answer:
[tex]A=2x^2+3x-5[/tex]
Step-by-step explanation:
Given that,
Length = (2x+5) cm
Width = (x-1) cm
We need to find the area of a rectangle. The formula for the area of rectangle is given by :
A = lb
[tex]A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5[/tex]
So, the required area is equal to [tex]2x^2+3x-5[/tex].

How many hours of service do the services cost the same?
Answers
Answer:
2.5 hours
Step-by-step explanation:
70x+25=50x+75
step 1 subtract 25 from each side
25-25 cancels out
75-25=50
Now we have
70x=50x+75
step 2 subtract 50 from each side
70x-50x=20x
50x-50x cancels out
now we have
20x=50
step 3 divide each side by 20
20/20 cancels out
50/20=5/2 or 2.5
so we can conclude that it will take 2.5 hours of service for the services to cost the same
Round to the nearest hundredth:7.884
Answers
Answer:
7.88
Step-by-step explanation:
Hope this helps :D
When rounding to the nearest hundredth, the number 7.884 becomes 7.88.
To round 7.884 to the nearest hundredth, we look at the digit in the thousandth place, which is 8.
Now, If the digit to the right is less than 5, you simply drop all the digits to the right and keep the desired decimal place unchanged.
If the digit to the right is 5 or greater, you round up the desired decimal place by increasing it by one. Drop all the digits to the right.
Since 8 is greater than or equal to 5, we round up the digit in the hundredth place.
Therefore, when rounding to the nearest hundredth, the number 7.884 becomes 7.88.

Hey There!
If you didnt know the given angles in the triangle added together equal the missing triangles supplement aka z+50
So all we have to do is set up an equation
z+50=30+6x-45
step 1 combine like terms
30-45=-15
now we have
z+30=6x-15
step 2 add 15 to each side
-15+15 cancels out
30=15=45
now we have
z+45=6z
step 3 subtract z from each side
z-z cancels out
6z-z=5z
now we have
45=5z
step 4 divide each side by 5
5/5 cancels out
45/5=9
z=5
so we can conclude that z=9

Given the function f(x) = 2 x + 61 - 4, for what values of x is f(x) = 6?
O x= -1, x = 11
Ox=-1, x = -11
O x= 14 = -26
O x= 26, x=-14
Answers
Answer:
[tex]x = -1[/tex] or [tex]x = -11[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 2|x+6| - 4[/tex]
Required
Find x when
[tex]f(x) = 6[/tex]
Substitute 6 for f(x)
[tex]6 = 2|x+6| - 4[/tex]
Add 4 to both sides
[tex]4+6 = 2|x+6| - 4+4[/tex]
[tex]10 = 2|x+6|[/tex]
Divide both sides by 2
[tex]5 = |x + 6|[/tex]
Rewrite as:
[tex]|x + 6| = 5[/tex]
This can be split to:
[tex]x + 6 = 5[/tex] or [tex]-(x + 6)=5[/tex]
Solve for x in both cases
[tex]x = 5 - 6[/tex] or [tex]x + 6 = -5[/tex]
[tex]x = -1[/tex] or [tex]x = -6 - 5[/tex]
[tex]x = -1[/tex] or [tex]x = -11[/tex]

philip has 11 coins that equal a total of 82 cents. His coins include at least 1 quarter 1 dime 1 nickel and 1 penny. how many of each coin does he have
Answers
Answer:
Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.
Step-by-step explanation:
Given that Philip has 11 coins that equal a total of 82 cents, and his coins include at least 1 quarter 1 dime 1 nickel and 1 penny, to determine how many of each coin does he have the following calculation must be performed:
Quarter = 0.25
Dime = 0.10
Nickel = 0.05
Penny = 0.01
0.82 - 0.25 - 0.10 - 0.05 - 0.01 = 0.41
0.41 = 0.10 x 4 + 0.1 (5 coins + 4 previous coins = 9 coins).
0.41 = 0.10 x 2 + 0.05 x 4 + 0.01 (7 coins + 4 previous coins = 11 coins).
0.25 + (3 x 0.1) + (5 x 0.05) + (2 x 0.01) = X
0.25 + 0.30 + 0.25 + 0.02 = X
0.82 = X
Thus, Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.
