Answer:
Width = w
Length = 4w + 6
Area = 130 in2
Area = W X L = 130
So, w X (4w + 6) = 130
4w2 + 6w = 130 by distributing
-130 -130
4w2 + 6w - 130 = 0
Step-by-step explanation:
Answer:
Area = 6L² - 4L
Step-by-step explanation:
Let length be L
Given Width, w is 4 less than 6 times length :
That is ,
6 times length = 6 L
4 less than 6 times length means = 6L - 4
Therefore Length = L
Width = 6L - 4
Area = Length x Width
= L x ( 6L - 4)
= 6L² - 4L
At the beginning of the school year, Liya's goal was to earn an A on
at least 85% of her 60 quizzes for the year. She earned an A on 35 of the first 40
quizzes. If she is to achieve her goal, on at most how many of the remaining
quizzes can she earn a grade lower than an A?
A: 1
B: 2
C: 3
D: 4
E: 5
Answer:
4
Step-by-step explanation:
If 15% of quizzes don't have to be A's, that means that its 9 quizes that can be lower than an A. She already lost 5 which means she has four left.
Answer:
D; 4
Step-by-step explanation:
Step 1:
Let us figure out exactly how many As Liya has to earn for the year. We must find 85% of 60:
[tex]85 \%\ of\ 60=\\\frac{85}{100}*\frac{60}{1}=\\\frac{85}{5} *\frac{3}{1} =\\17*3=\\51[/tex]
Liya must earn 51 As this year to reach her goal. This also means that she can earn 9 grades lower than an A to still reach her goal ([tex]60-51=9[/tex]).
Step 2:
So far, Liya has earned 35 As out of 40 tests in total. This means that so far, Liya has earned 5 test grade lower than an A:
[tex]40-35=5[/tex]
In total, Liya can only have 9 grades lower than an A. Therefore:
[tex]9-5=\fbox{4}[/tex]
Liya can only earn [tex]\fbox{4}[/tex] grades lower than an A in the remaining quizzes.

Tommy has a rectangular-shaped swimming pool. He wants to know the volume of water in the pool, but he is not sure what the width of the
pool is. He knows the relationship between the width and the length and height of the pool. He used this relationship to come up with the
following equation to find the volume of the pool when the width is w meters.
A. Z
B. X
C. Y
D. W
Answer:
it is x
Step-by-step explanation:
The volume of a shape is the amount of space in it.
The graph that satisfies the above condition is the (b) graph X:
The volume of a rectangular-shaped swimming pool is
[tex]\mathbf{V=l \times w \times h}[/tex]
Where:
[tex]\mathbf{l,w,h \ge 0}[/tex] ---all the dimensions are greater than 0
[tex]\mathbf{l,w,h \ge 0}[/tex] means that:
The graph of V must have three x interceptsThe graph of V must not pass through the origin (0,0)From the given graphs, the graph that satisfies the above condition is the graph X:
This is so because it crosses the x-axis three times, and it does not pass through the origin

One evening the Scotts went to the Chalet Restaurant for
dinner. The bill was $67.65. Mr. Scott paid with four $20 bills.
How much change should he have received?
Given:
Total bill = $67.65
Mr. Scott paid with four $20 bills.
To find:
The amount of change he have received.
Solution:
It is given that, Mr. Scott paid with four $20 bills. So, the total amount paid by him is:
[tex]\$20\times 4=\$80[/tex]
Total bill = $67.65
Now,
Amount of change = Total amount paid - Total bill
= $80 - $67.65
= $12.35
Therefore, he should have received $12.35.

Supplementary Angels means the angles are added up to 180 degrees.
So , <1 + <2 = 180
Given that,
<1 = 2x +6
Now lets find the size of <2.
We know that,
Angles in a Straight line is also added up to 180 degrees.
So,
<2+ < 3 = 180
Let's Solve.
[tex] < 2 + < 3 = 180 \\ < 2 +( 3x - 6) = 180 \\ < 2 = 180 - (3x - 6) \\ < 2 = 180 - 3x + 6 \\ < 2 = 186 - 3x[/tex]
Now we know the size of <2
lets find out the value of x
[tex] < 1 + < 2 = 180 \\ 2x + 6 + 186 - 3x = 180 \\ 186 + 6 - 180 = 3x - 2x \\ 12 = x[/tex]
Let's check whether the answer is correct.
We know that <1 =<3 (Alternative Angles)
[tex] < 1 = < 3 \\ 2x + 6 = 3x - 6 \\ 2 \times 12 + 6 = 3 \times 12 - 6 \\ 24 + 6 = 36 - 6 \\ 30 = 30[/tex]

A board 180 cm long is cut into two pieces such that 3 times the length of the larger piece is 85 cm longer than 4 times the length of the smaller piece. How long are the two pieces of board?
Answer:
smaller piece is 65cm
larger piece is 115cm
Step-by-step explanation:
let 's' = smaller piece
let '180-s' = larger piece
3(180-s) = 85 + 4s
540 - 3s = 85 + 4s
540 = 85 + 7s
455 = 7s
s = 455/7 which is 65cm
larger piece = 180-65 or 115cm

Answer:
c(x) = 16x + 22736
R(x) = -2x^2 + 524x
[ -2x^2 + 508x - 22736] = 0
Factored: f(x) = -2(x - 196)(x - 58)
58 to break even
Step-by-step explanation:
Your cost is the amount it cost you to "make" stuff.
You have fixed and variable costs (cost of oven is fixed cost of flower and sugar is variable to make cupcakes)
your cost is c(x) = 16x + 22736
"your oven and building cost $22736 per month and you use $16 worth of sugar butter flour to make one cupcake ( it must be a huge one) ...
your revenue is the amount of money that "comes into your business"...
the amount of money in the cash register.... Note: this is only money IN you still have to pay for the building, sugar flour etc.
R(x) = -2x^2 + 524x
Note: the minus and the square basically say that the more you charge the less cupcakes you will sell...
Profit is the money in minus the money out
P - R - E [ -2x^2 + 524x ] - [16x + 22736]
the break even point is where the two functions are the same
in other words where C=R or R-C=0
[ -2x^2 + 524x ] = [16x + 22736]
[ -2x^2 + 508x - 22736] = 0
Factored: f(x) = -2(x - 196)(x - 58)
Answer:
Step-by-step explanation:
C(x)=16x+22736
R(x)=-2x²+524x
P(x)=R(x)-C(x)
=-2x²+524x-16x-22736
=-2x²+508-22736
when profit is zero then no gain or loss.
so -2x²+508x-22736=0
or x²-254x+11368=0
196+58=254
196×58=11368
x²-54x-196x+11368=0
x(x-54)-196(x-54)=0
(x-54)(x-196)=0
x=54,196
so x=54 is the smallest number of bins to break even.
