Answer:
2a. (360x +495)/(8x +11) = 45
2b. 2((8x+11) +45) = 16x +112
Step-by-step explanation:
a) The area is the product of length and width.
A = LW
We are given ...
W = 8x +11
A = 360x +495
The value of length can be found by solving for L:
L = A/W
L = (360x +495)/(8x +11)
The long-division solution to this is shown in the attachment.
L = 45 . . . . simplified expression for length
__
b) The perimeter of the tank is twice the sum of length and width:
P = 2(L +W)
Substituting the values for L and W, this is ..
P = 2(45 +(8x +11)) . . . . expression for length of edge seal
P = 2(8x +56)
P = 16x + 112 . . . . . . simplified expression for seal length
−[(−r) + 2p] = −(−r) − 2p

You are going on a long trip and want to calculate your Miles per gallon. When you start your trip your odometer read 95842 miles. At the end of your trip your odometer reads 95975 miles. You started with a full tank and to return to a full tank you put in 7 gallons of gas total. What is your miles per gallon?
Answer:
19 miles per gallon
Step-by-step explanation:
95975 - 95842 = 133
133 divided by 7 = 19
At 5:00pm the temperature read 10° above zero. At midnight it read 4 ° below zero. Find the change
in temperature.
A. 2
B. -2
C. 1/2
D. -1/2
Rate of change is the slope.
The slope is the change in Y over the change in X:
Slope = (5- -3) / (2 - -2)
Slope = 8/4
Slope = 2

If a + b = 20 and ab = 75, find the value of a? + b2.
Answer:
a² + b² = 250
Step-by-step explanation:
Given
a + b = 20 ( square both sides )
(a + b)² = 20² , that is
a² + b² + 2ab = 400 ( substitute ab = 75 )
a² + b² + 2(75) = 400
a² + b² + 150 = 400 ( subtract 150 from both sides )
a² + b² = 250

1) will yield consecutive odd integers.
2k+9, 2k+11, 2k+13
or
3k+2, 3k+3 , 3k+4
2)will yield consecutive integers.
k+6, k+8 , k+10
or
k+1, k+2, k+3
Answer:
Part A. Option a. is correct
Part B. Option a. is correct.
Step-by-step explanation:
Part A.
The numbers given by 2k + 9, 2k + 11, 2k + 13 will represent 11, 13 and 15 for k = 1, which are consecutive odd integers.
And the numbers given by 3k + 2, 3k + 3 and 3k + 4 will represent 5, 6, and 7 for k = 1 and they are not consecutive odd integers.
Therefore, option a is correct.
Part B.
The numbers given by k + 1, k + 2, k + 3 will represent 2, 3 and 4 for k = 1, which are consecutive integers.
And the numbers given by k + 6, k + 8, and k + 10 will give 7, 9, and 11 for k = 1 and they are not consecutive integers.
Therefore, option A is correct.

70° ? 127° 146° Can I get some help with this?
Answer:
93 degrees
Step-by-step explanation:
First, you would need to observe the image and see where to start off. You can see that there is a triangle below the "?" and you would be able to get the answer if you can find the measures of the small triangle(because of vertical angles) So,
180-127= 53.
180-146=34.
Since the angles of a triangle adds up to 180 degrees, 53+34+x=180.
x=93
Now, just flip the angle around and "?" = 93 degrees.
Answer: 93 degrees
===========================================================
Explanation:
Let x be the question mark angle we want to find.
Let y be adjacent to the 127 degree angle
Let z be adjacent to the 146 degree angle.
Refer to the diagram below.
Note that in the diagram, I have a second copy of 'x' because the two x angles are vertical angles. Vertical angles are always congruent.
Let's find angle y
127+y = 180
y = 180-127
y = 53
Do the same for angle z
z+146 = 180
z = 180-146
z = 34
Then notice how,
x+y+z = 180
x+53+34
x+87 = 180
x = 180-87
x = 93
Which is true when a negative number is subtracted from a positive number?
A. The difference is always zero.
B. The difference is always positive.
C. The difference is always negative,
D. The difference could be positive or negative
Answer:
D is the correct answer
Step-by-step explanation:
it honestly depends on what the numbers are
for example, 12 -6, you would get 6.
but if the question is something like 4 -8, you'd have -4

Sandi got 1/1/4 pounds of gummy worms if she left the store with 3 pounds of gunmys worms and skittles ,how many pounds of skittles did she get
Answer:
1 3/4 lbs of skittles
Step-by-step explanation:
Easy way: 3lbs - 1 1/4lbs = 1 3/4lbs
Complex way:
(I'm assuming "1/1/4" means "1 1/4")
This is simply ~Subtraction~
The total is 3lbs(t) and 1 1/4 of that 3lbs is gummy worms(g). What is left of the 3lbs is skittles(s).
So we need to know what added to 1 1/4 equals 3.
Equation: t= 1 1/4 + s
Equation: t= 1 1/4 + s
We can replace (t) with 3 because we know this variable.
1. 3= 1 1/4 + s
To isolate the variable (s) we need to subtract 1 1/4 on both sides of the equation
2. 3(- 1 1/4)= 1 1/4(- 1 1/4) + s
The right side cancels out = 0 and the left = 1 3/4
3. 1 3/4= s
Flip it around for the traditional view
4. s = 1 3/4
In word form: Skittles equal 1 3/4 (don't forget to add lbs or pounds back into the final answer)

An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?
Answer:
3.33%
Step-by-step explanation:
60 = theoretical/actual degree measure
62 = experimental/calculated degree measure
% error = (|actual - calculated|/actual)*100
In words, the absolute value of the actual value minus the calculated value is first calculated. Then, divide the difference by the actual value that you should have obtained. Since you want this converted to a percent, multiply the decimal value of your quotient by 100.
Three significant figures is 3.33 because none of these numbers are leading or trailing zeros. If you count how many numbers (that are not leading or trailing zeros) the value 3.33 has, you'll find 3 significant figures, which is why your final answer should be 3.33%.
