Answer:
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
Step-by-step explanation:
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
She need 3 pounds of Chocolate chip cookies and Walnuts
Let us represent
Number of bags of chocolate chip cookies = x
Number of bags of walnuts = y
She need 3 pounds of Chocolate chip cookies and Walnuts
Hence,
We have to convert oz (ounces) to pounds
For chocolate chip cookies
1 oz = 0.0625 pound
12 oz = x
Cross Multiply
x = 12 × 0.0625 pound
x = 0.75pound
For Walnuts
1 oz = 0.0625 pound
4 oz = x
Cross Multiply
x = 4 × 0.0625 pound
x = 0.25pound
Hence,
0.75 pound = $3
0.25 pounds = $2
She can only spend $15
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
Hence,
0.75x + 0.25y = 3..... Equation 1
3x + 2y = 15.... Equation 2
Multiply Equation 1 by 2 and Equation 2 by 0.25
1.5x + 0.5y = 3... Equation 3
1.5x + 4y = 30.... Equation 4
Subtract Equation 3 from 4
3.5y = 27
y = 27/3.5
y = 7.7 bags
Solving for x using Equation 2
3x + 2y = 15.... Equation 2
3x + 2(7.7) = 15
3x + 15.4 = 15
3x = 0.4
x = 0.4/3
x = 0.133 bags
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags

Kelly rides the bus to work d days each month. She pays a fare of $2.25 each time. On t of those days, she pays an additional fare of $0.75 to transfer onto another bus. The expression shown can be used to find her total cost for bus fare for the month.
d × 2.25 + t × 0.75
Which statement explains how to find Kelly’s total bus fare for the month?
Answers
Answer: A: find the product of D and $2.25 and the product of t and $0.75. Then find the sum of the two products.
The total fare for the bus can be found by first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
The total fare for the bus can be calculated using the expression
d × 2.25 + t × 0.75
Here d is the total days that Kelly worked in a month.
On each of these days, she pays a fare of $2.25.
Total fare now = d × 2.25
Find this product.
There is also an additional fare of $0.75 to transfer onto another bus on t of these days.
Additional fare = t × 0.75
Find this product.
Add the resultant both products.
Hence the statement which explains how to find Kelly's total bus fare for the month is first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.

how many solutions will this quadratic equation x^2+8x+16 has?
Answers
Answer:
one solution
Step-by-step explanation:
to find out how many solutions a quadratic equation (with the equation ax²+bx+c) will have, we need to find the discriminant, which is b²-4ac
first, we can label the coefficients as a, b, and c
a=1 (1 is in front of x²)
b=8
c=16
now substitute into the formula
D=(8)²-4(1*16)
D=64-64
D=0
the discriminant is 0
when the discriminant is 0, that means the quadratic equation only has one solution.

Answers
Answer:
$131.85
Step-by-step explanation:
First, we need to find the net price (after discount and tax) It's a 15% discount, so just find 85% (100-15=85) of the original price. You'll get $373.15.
For tax, multiply by 1.06, since it's a 6% tax (1+.06). You'll get $395.539.
You're paying over 3 months time, so to find payment each month just divide by 3.
395.539/3 = 131.8463333
Round to 131.85
Your answer is $131.85 dollars per month

What are two numbers that when multiplied equal -30 and when added together equal 1?
Answers
Answer:
5 and 6
Step-by-step explanation:
-5 x 6 = -30
-5 + (6) = 1
x2 + 1x - 30 = 0
(X - 5 ) (X + 6)
To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:
x2 + 1x - 30 = (X - 5 ) (X + 6)
Jameson and Quincy each deposit $7,000 into accounts that earn 6% interest, but Jameson earns annual simple interest while Quincy earns annual compound interest. Assuming neither one of them makes any deposits or withdrawals for 5 years, which of the following is a true statement?

Jameson will have about $267.58 less in his account than Quincy.
Jameson will have about $2,367.58 more in his account than Quincy.
Jameson will have about $2,100 more in his account than Quincy.
Answers
Answer:
$267.58
Step-by-step explanation:
Jameson: simple interest
6% =.06 .06 x 5 = .3 .3 x 7000 = 2,100 = interest
6% =.06 .06 x 5 = .3 .3 x 7000 = 2100 2100 + 7000 = 9,100 = total
Quincy: compound interest
6% =.06 .06 x 5 x 1 = .3 x 7000 = 2100
6% =.06 .06 x 5 x 1 = .3 x 7000 = 2100 + 7000 = 9100
.06 x 5 x 1 x 9100 = 2730 + 9100=11830
repeat five times u would get a interest of 2,367.58
and a total of 9,367.58
the total amounts 9,367.58 - 9,100 = 267.58
the interests 2,367.58 - 2,100. = 267.58

Jensen has an above ground pool in the shape of a regular octagon. Opposite sides are 25 feet apart and each side is 10.4 feet long. It requires 7.5 gallons to fill one cubic foot. How much water is need to fill the pool with 3 feet of water.
A. 3900
B. 5850
C. 1560
D. 11700
Answers
Answer:
D
Step-by-step explanation:
To solve this question we can use the area formula for an octagon.
It is as follows:
A=2(1+√2)a^2
where "A" is the total area and "a" is the length of a side.
Plug in our side length a=10.4
A=2(1+√2)10.4^2
≈522.24268
Alternatively, you can split the octagon into 8 equal triangles.
The base of each triangle would be 10.4 and the height would be 12.5 since opposite sides are 25 feet apart. (25/2)
The area of a triangle would then be:
A=1/2bh
where "b" is base and "h" is height
A=125*10.4*1/2
=65
Since there are 8 we multiply that by 8 for the area of an octagon
65*8=520
The area of the octagon base is 520 square feet.
I'll use this value to do my calculations as it is more exact.
Now, using this area, we need to find the volume of the pool we are meant to fill.
To do this, we simply multiply the area of the base by the height.
520*3=1560
Now, we know that the volume of the pool is 1560 cubic feet.
Each cubic foot takes 7.5 gallons to fill.
1560*7.5=11700
Therefore, the pool takes 11700 gallons of water to fill.

512 cm3252 cm2Step-by-step explanation:
The first dimension to measure is length. Length is always the longest side of the box that has a flap. The next dimension is width. The width side also has a flap but is always the side shorter than the length. Measure the height of the package. Height is the only dimension without a flap.Area of a square = side times side. Since each side of a square is the same, it can simply be the length of one side squared. If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches. (Square inches can also be written in2.)Perimeter of the rectangle = PQ + QR + RS + SP
= b +l + b + l
= 2b +2l
Again,
ABCD is a rectangle. We know that the opposite sides of a rectangle are equal.
Perimeter of a Rectangle
AB = CD = 5 cm and BC = AD = 3 cm
So, the perimeter of the rectangle ABCD = AB + BC + CD + AD = 5 cm + 3 cm + 5 cm + 3 cm = 16 cm
It can be written as 5 cm + 5 cm + 3 cm + 3 cm
= (2 × 5) cm + (2 × 3) cm
= 2 (5 + 3) cm
= 2 × 8 cm
= 16 cm
We add length and breadth twice to find the perimeter of a rectangle.

The average mass of 5 man basketball team is 70Kg. Four of team members have a mass of 50kg, 62kg, 81kg, and 84kg What is the mass of the fifth player???? 15 POINTS!!!
Answers
Answer:
The mass of the fifth player is 73 kg
Step-by-step explanation:
Since the average mass of the 5 players is 70kg
what this mean is that the total sum of all the masses of the players is equal to the product of 5 and 70 kg
we have this as 5 * 70kg = 350 kg
So, by adding the masses of all the players, we get 350kg
Thus, for us to get the mass of the 5th player, we have to subtract the sum of the remaining 4 from the total 350kg
Mathematically, we have this as;
350 - ( 50 + 62+ 81 + 84) = 73 kg

Answers
Mary got 9.37%. discount .
What is percentage discount?A percentage discount is a reduction in the price of a good or service that is expressed as a number of hundred. A 20 percent reduction, for instance, would result in an item that was originally $100 costing $80.Given ,
discount = 11%
So,
((8000x0.110) + (17000x0.086)) = 2342
⇒ 2342 / (8000+17000) = 2342/25000
= 0.0937 or 9.37% discount.
The percentage discount allowed all together was 9.37%.
