Answer:
13.2
Step-by-step explanation:
Let 4x represent the chocolate chip cookies
Let 3x represent the spice cookies
Let 3x represent ginger cookies
4x + 3x + 3x = 33
10x = 33
x = 33/10
x = 3.3
Since 4x represents chocolate chip cookies
4 × 3.3
= 13.2
Hence there are 13.2 chocolate chip cookies

Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? If Isaac uses a coupon entitling him to a 25% discount off the purchase price before tax, how much will his bill be? Assume that a 7% sales tax is applied to the discounted price. Using words, explain how you found the discounted price.
What is the slope of the line perpendicular to the line with equation 4x-5y+13=0
Answer:
m = - 5/4
Step-by-step explanation:
If two lines are perpendicular, their slopes are negative reciprocals, which means that their product is -1
We can write the equation
4*x - 5*y + 13 = 0
as: 5*y = 4*x + 13 or
y = (4/5)*x + 13 (1)
Equation (1) is the equation of a straight line in its slope point form, 4/5 is the slope, according to this the slope of a perpendicular line is
-5/4

Sean mixes coconut oil with several other ingredients to make homemade toothpaste for his dog Rocky. He uses 1/2 cup of coconut oil to make 2/3 cup of toothpaste. How much coconut oil does Sean use per cup of toothpaste?
Answer:
3/4 cup of coconut
Step-by-step explanation:
Given:
[tex]\frac{1}{2}[/tex] cup of coconut for [tex]\frac{2}{3}[/tex] cup of toothpaste
Required
Determine how much oil for a cup of toothpaste
Represent Coconut with C and Toothpaste with T;
So,
When
[tex]C = \frac{1}{2}\ \ T = \frac{2}{3}[/tex]
We're to solve for
C when T = 1
This can be represented as:
[tex]\frac{1}{2} = \frac{2}{3}[/tex] --- 1/2 to 2/3
[tex]C = 1[/tex]
Cross Multiply:
[tex]C * \frac{2}{3} = \frac{1}{2} * 1[/tex]
[tex]\frac{2}{3}C = \frac{1}{2}[/tex]
Solve for C
[tex]C = \frac{1}{2}/\frac{2}{3}[/tex]
[tex]C = \frac{1}{2}*\frac{3}{2}[/tex]
[tex]C = \frac{3}{4}[/tex]
This means Sean needs 3/4 cup of coconut oil

Gary's pay is $15 per hour. He receives a 6% pay raise.
The question is incomplete, the complete question is;
Gary's pay is $15 per hour. He receives a 6% pay raise.
Which method can Gary use to correctly calculate his new hourly pay rate?
Choose Yes or No for each method.
Answer:
Multiply 15 by 0.06 and add the result to 15 is the correct method
Step-by-step explanation:
Now when you are told to obtain the percentage, it simply means to multiply the given percentage by the number.
Here is what i mean;
6% of 15 simply means
6/100 * 15
Or
0.06 * 15 = 0.9
Since his basic pay of $15 was increased by this percentage, we have to add $0.9 so we have;
15 + 0.9 = $ 15.9

Thomas can process a pile of paperwork in 4 hours less time than Frank. Together they can process the pile in 2.1 hours. How long would it take Frank to do the job alone?
Answer:
F = 7 hours
Step-by-step explanation:
Let the time taken by Frank to work alone be F.
Translating the word problem into an algebraic equation;
Thomas alone takes (F - 4) hours.
Combine time = 2.1 hours
Their individual work rate expressed in piles per hour are;
Frank = 1/F
Thomas = 1/(F - 4)
Combined rate = 1/F + 1/(F - 4)
Simplifying the equation, we have;
Combined rate = (F - 4 + F)/F(F - 4)
Combined rate = (2F - 4)/F(F - 4)
Combined rate = (2F - 4)/(F²- 4F)
Now to find the time taken when they work together is;
(2F - 4)/(F²- 4F) = 1/2.1
Cross-multiplying, we have;
2.1*(2F - 4) = F² - 4F
4.2F - 8.4 = F² - 4F
Rearranging the equation, we have;
F² - 4.2F - 4F + 8.4 = 0
F² - 8.2F + 8.4 = 0
Solving the quadratic equation by factorization;
Factors = -7 and -1.2
F² - 7F - 1.2F + 8.4 = 0
F(F - 7) - 1.2(F - 7) = 0
(F - 7)(F - 1.2) = 0
Therefore, F = 7 or 1.2 hours
The time taken by Frank alone would be 7 hours.

What is the approximate circumference of the circle shown below
Answer: A) 46.5 cm
Step-by-step explanation:
Circumference = 2 π r or Circumference = π d
In this case, they give us the diameter = 14.8 cm. Therefore the radius = 14.8/2 = 7.4 cm.
π ≈ 3.14.
We can use either equation above, but because the diameter was given, we will use c = πd for simplicity.
C = π d
= (3.14)(14.8)
= 46.47 cm, which rounds to 46.5 cm

Karen and James both had 30 stocking stuffer items on their shopping list. After black Friday shopping Karen had finished 35% of her shopping After black Friday shopping James had finished 60% of his shopping HOW MANY MORE items has James purchased than Karen?
Answer: 7.5 items
Step-by-step explanation:
Both Karen and James had 30 stocking items.
Karen bought 35% of her items;
= 35% * 30
= 10.5 items
James has bought 60%;
= 60% * 30
= 18 items
= 18 - 10.5
= 7.5 items
Given that f(x) = x^2 + 16x + 63 and g(x) = x + 9, find f(x) + g()
Answer:
f(x) + g(x) = x² + 17x + 72
If you want to factor that, then it comes out as:
f(x) + g(x) = (x + 8)(x + 9)
Step-by-step explanation:
[tex]f(x) + g(x)\\= x^2 + 16x + 63 + x + 9\\= x^2 + 17x + 72\\= (x + 8)(x + 9)[/tex]

How can I find the answer for number 1 and 4 with explanation?
Answer:
Concept: Sequences & Series
The hint here is to try to find the common factor, you asked us to solve 1 so see the solution below.
1,-3,9, -27 : We see a common base of 3 hence we can find that the series representation is [tex]( - 3) ^{n-1} [/tex]Next we can find the next 3 terms by just plugging in the values
We want the 6th, 7th, and 8th term
So we plug 6 in for n and 7 in for n and 8 in for n
So we get the 6th term=-243
The 7th term= 729
The 8th term= -2187
Answer:
Step-by-step explanation:
1) 1 , -3 , 9 , -27 , 81 ,...........
It is Geometric sequence
ratio = 2 term ÷ first term = -3 ÷ 1 = -3
1st term = 1
2nd term = 1 * -3 = -3
3rd term = -3 *(-3) = 9
4th term = 9 *(-3) = - 27
6th term = 81 *(-3) = -243
7th term = -243 *(-3) = 729
8th term = 729 *(-3) = -2187
Next 3 terms: - 243 , 729 , - 2187,....
4)
[tex]\frac{1}{2}, \frac{1}{2} , \frac{3}{8} , \frac{1}{4} ,\frac{5}{32},.....\\\\\\Rule = \frac{n}{2^{n}}\\Term1 = \frac{1}{2^{1}}=\frac{1}{2}\\\\Term2 = \frac{2}{2^{2}}=\frac{2}{4}=\frac{1}{2}\\\\Term3 = \frac{3}{2^{3}}=\frac{3}{8}\\\\Term4 = \frac{4}{2^{4}}=\frac{4}{16}=\frac{1}{4}\\\\Temr5 = \frac{5}{2^{5}}=\frac{5}{32}\\\\Term6 = \frac{6}{2^{6}} = \frac{6}{64} = \frac{3}{32}\\\\Term7 = \frac{7}{2^{7}}=\frac{7}{128}\\\\Term8 =\frac{8}{2^{8}} = \frac{8}{256}=\frac{1}{32}\\\\[/tex]
