A food store makes a 11-lb mixture of oatmeal, crispies, and chocolate chips. The cost of oatmeal is $1.50 per pound, crispies cost $2.00 per pound, and chocolate chips cost $1.00 per pound. The mixture calls for twice as much oatmeal as crispies. The total cost of the mixture is $17.00. How much of each ingredient did the store use?
Answer:
6 pounds of oatmeal, 3 pounds of crispies and 2 pounds of chocolate chips were used.
Step-by-step explanation:
Let,
x be the pounds of oatmeal used
y be the pounds of crispies used
z be the pounds of chocolate
According to given statement;
1.50x+2.00y+1.00z = 17.00 Eqn 1
x+y+z = 11 Eqn 2
x = 2y Eqn 3
Putting x=2y in Eqn 2
2y+y+z = 11
3y+z = 11 Eqn 4
From Eqn 4
z = 11 - 3y Eqn 5
Putting value of x and z from Eqn 3 and Eqn 5 in Eqn 1
1.50(2y) + 2.00y + 1(11-3y) = 17.00
3y+2y+11-3y=17
[tex]2y=17-11\\2y=6\\\frac{2y}{2}=\frac{6}{2}\\y=3[/tex]
Putting y = 3 in Eqn 3
x= 2(3)
x= 6
Putting in Eqn 2
6 + 3 + z = 11
z = 11-9
z= 2
Hence,
6 pounds of oatmeal, 3 pounds of crispies and 2 pounds of chocolate chips were used.

Fiona works part time for a legal firm. She can work a maximum of 30 hours
per week.
Let hours = x
She can work a maximum of 30 hours so x can be any number from 30 or below.
The inequality would be: X <= 30
Answer:
Let the maximum time be x
She can work 30 hrs or below ( maximum of 30 hrs)
Therefore, the equation is
[tex] \huge \boxed{x \leqslant 30 \: hours}[/tex]

Answer:
x = 11, CD = 74, DE = 74, and CE = 37
Step-by-step explanation:
9x-25 = 6x+8
3x - 25 = 8
3x = 33
x = 11
CD = 9x - 25 = 99 - 25 = 74
DE = 6x+8 = 66 + 8 = 74
CE = 10x - 73 = 110 - 73 = 37

Answer:
One solution
Step-by-step explanation:
maybe
Answer:
There is only one solution to the equation.
x = 0
Step-by-step explanation:
Let rewrite the following equation so that x will be separated from the other numbers. So we do the following......
[tex]\frac{x+4}{4} = \frac{x +3}{3}[/tex]
[tex]12(\frac{x+4}{4}) = 12(\frac{x +3}{3})[/tex]
[tex]3(x +4) = 4(x+3)[/tex]
[tex]3x +12 = 4x +12[/tex]
[tex]12 = 4x - 3x +12[/tex]
[tex]0 = x[/tex]

The product of two numbers decreased by six is less than 30. Write an algebraic expression, but do not solve. *
Answer:
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6
xy < 36
Step-by-step explanation:
Let us represent:
First number = x
Second number = y
The product of two numbers decreased by six is less than 30.
The algebraic expression is given as
(x × y) - 6 < 30
xy - 6 < 30
xy < 30 + 6
xy < 36
Find the nth term of this quadratic sequence.
3, 11, 25, 45
Answer:
3 , 11, 25, 45
Diff 8 14 20
Diff 6 6
The second differences are the same. The sequence is quadratic and will contain an n^2 term. The coefficient of n^2 is always half of the second difference. In this example, the second difference is 6. Half of 6 is 3 so the coefficient of n^2 is 3
therefore 3n^2
3 11 25 45
3n^2 3 12 27 48
Remainder 0 -1 -2 -3
Difference -1 -1 -1
linear sequence with nth term -n+1
so nth term of quadratic sequence in 3n^2-n+1

Here is a story: Lin bought 4 bags of apples. Each bag had the same number of apples. After eating 1 apple from each bag, she had 28 apples left. А. 28 1.

Step-by-step explanation:
17 apples and 12 oranges cost $10.44. 3 apples and 4 oranges cost $2.84. How much does 1 orange cost?
Answer:
0.48$
Step-by-step explanation:
Cost of 1 Apple = A
Cost of 1 Orange = O
Six apples and three oranges cost $3.36 equivalent to:
6A + 3O = 3.36 (1st equation).
Two apples and five oranges cost $3.04 equivalent to:
2A + 5O = 3.04 (2nd equation).
Now we have to solve the 2 equations with 2 uknowns (the cost of 1 Apple = A, and the cost of 1 Orange = O).
6A + 3O = 3.36 (Equation 1)
2A + 5O = 3.04 (Equation 2), multiplying this equation by 3 we get:
6A + 3O = 3.36 (Equation 1)
6A + 15O = 9.12 (Equation 2), Now equation 2 minus equation 1 we get:
6A-6A +15O -3O = 9.12-3.36 equivalent to:
12O = 5.76 => O = 5.76/12 = 0.48 ( the cost of one Orange is 0.48$)
Go back to equation 1 and solve for the cost of 1 apple:
6A + 3x0.48 = 3.36 =>
6A + 1.44 = 3.36 =>
6A = 1.92 =>
A = 1.92/6 = 0.32 ( the cost of one apple is 0.32$)
Summary: The cost of one apple is 0.32$ and the cost of one orange is 0.48$.
Find all possible solutions for x and y such that △ABC is congruent to △DEF.
△ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.
△ABC ≅ △DEF when x is ___ and y is ___.
Answer:
Step-by-step explanation:
it means the ABC And DEF have side lengths of 15,19, 25
so 3x-3 = 15
x = 6
5-y = 19
so y = -14
Find the next three terms of the following arithmetic sequence. -10, -3, 4, 11, (Three missing numbers)
Answer:
You can find the difference of two numbers easier if you take the absolute value of them (which is canseling out the negative or positive of them, and figuring out how far away from 0 they are) |-10| = 10, |-3| = 3, the difference between 10 and 3 is 7. The only problem that arises is now we are dealing with and negative and a positive, for this one you must see that to get from -3 to zero, you need to add 3, and to get from 0 to 4, you need to add 4, if you add 3, and then 4, you get 7
The difference between 10 and 3 is 7
The difference between -3 and 4 is 7
So naturally, the next number will be 4 + 7 = 11

1. The list of ordered pairs represents a function: (12,6) (3,1) (2,-2) (5,10) (-8,-4) ( _, _)
Which of the following could be the missing ordered pair?
A. (2,1)
B. (12,7)
C. (-8,8)
D. (-3,-4)
2. Rita works at a gym where she gets paid $450 each week plus $15.50 for any new gym membership she sells. If y represents the total pay per week and x represents the number of new memberships sold, which of the following equations represents a higher rate per membership sold.
A. y =31/3x + 500
B. y =15x + 425
C. y =33/2x + 425
D. y =15.05x +475
Answer:
1. D
2. y = 15.50x + 450
Step-by-step explanation:
1. Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice.
2. x > (y - 450)/ 15.50
i) Rita gets paid $450 per week.
ii) She gets $15.50 for every new membership she sells.
iii) let y represent the total pay per week.
iv) let x represent the number of new memberships sold.
v) the equation representing total pay is y = 15.50x + 450.
vii) therefore the equation that represents a higher rate of membership sold is given by x > (y - 450)/ 15.50

The base of 40-foot ladder is 8 feet from the wall. How high is the ladder on the wall (round to the nearest foot)
Given:
The base of 40-foot ladder is 8 feet from the wall.
To find:
How high is the ladder on the wall (round to the nearest foot).
Solution:
Ladder makes a right angle triangle with wall and ground.
We have,
Length of ladder (hypotenuse)= 40 foot
Base = 8 foot
We need to find the perpendicular to get the height of the ladder on the wall.
Let h be the height of the ladder on the wall.
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Base^2+Perpendicular^2[/tex]
[tex](40)^2=(8)^2+(h)^2[/tex]
[tex]1600=64+h^2[/tex]
[tex]1600-64=h^2[/tex]
[tex]1536=h^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{1536}=h[/tex]
[tex]\pm 39.1918358=h[/tex]
Height cannot be negative. Round to the nearest foot.
[tex]h\approx 39[/tex]
Therefore, the height of the ladder on the wall is 39 foot.
