You're planning on making 7 meatloafs for a party. You go to the store to buy breadcrumbs, and see they are sold by the canister. How many canisters do you need to buy? First, determine what information you need to answer this question, then click here to display that info (along with other info). How much breadcrumbs does the recipe call for? It calls for 1 1/4 cups of breadcrumbs. How many meatloafs does the recipe make? It makes 1 meatloaf. How many people can 1 meatloaf feed? It says it serves 8. How big is the canister? It is cylindrical, 3.5 inches across and 7 inches tall. What is the net weight of the contents of 1 canister? 15 ounces. How much does a canister cost? $2.19 How much does a cup of breadcrumbs weigh? I'm not sure, but maybe something from the nutritional label will help. Nutritional label showing the serving size is 1/3 cup (30g), and there are about 14 servings per container.

D. -0.2y and 2
E. -6 and -2
2y = -1x -8
rewrite each of the following equations in y= mc + b form
Answer: y=-1x-8
Step-by-step explanation:
The first step is to: Move the 'X' to the right side of the equation.
The second step is to: Divide the 'Y'
But since the 'X' is already on the right side you will just divide the 'Y'. If the 'X' was on the left then you will follow those steps that I gave you at the beginning in order to get it in the y=mx+b.
So it will look like this:
2y=-1x-8
y=-1x-8
y= -1(is the slope)x-8(is the Y-intercept)
So, if you have to graph this you will graph it starting with negative 8 as the y-intercept. Then you will go down one and over 1.

Answer:
1/3x - 2y - 5x + 8
Step-by-step explanation:
Given:
1/3x - 2y - 5x + 8
1. There are four (4) terms in the expression: 1/3x, -2y, -5x, 8
2. Like terms are terms which have the same thing in common such as 1/3x, -5x in the expression
3. A constant is a term without a variable. 8 is the constant in the expression
4. The variables in the expression are: x and y
5. The coefficients are; 1/3, -2, and -5

Answer:
6.7cm
Step-by-step explanation:
We apply Pythagoras Theorem twice.
First we find out the diagonal of the base of the cuboid.
The diagonal of the base = sqrt (2^2+4^2) = sqrt (20).
Then we find out AB by applying Pythagoras Theorem.
AB^2 = 5^2 + [sqrt (20)]^2
AB^2 = 45
AB = 6.7cm (correct to 1 decimal place)

Paula can spend no more than $500 for a photographer to take specialty photos for the dinner. Aerial photos from a drone cost $25 each, and wide-angle photos costs $50 each. Suppose the photographer takes 11 aerial photos. What is the maximum number of wide-angle photos that Paula can afford?
Answer:
4
Step-by-step explanation:
because 25×11= 275 and 500-275 =225
50x4=200
225-200=25 you can buy 4 and 25$ is left over

Solve the following system of equations:
y = 2x +1
y=-x+ 4
x=?
y=?
Answer:
x = 1, y = 3
Step-by-step explanation:
Given the 2 equations
y = 2x + 1 → (1)
y = - x + 4 → (2)
Substitute y = 2x + 1 into (2)
2x + 1 = - x + 4 ( add x to both sides )
3x + 1 = 4 ( subtract 1 from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into (1) and evaluate for y
y = 2(1) + 1 = 2 + 1 = 3
Then solution is x = 1, y = 3
Combine as indicated by the signs. 2x/y2-x2 - x/y-x
Answer: (2x - xy - x^2) / (y + x)(y - x)
Step-by-step explanation: *graded correct
First simplify: 2x / y^2 - x^2 = 2x / (y+x)(y-x)
Next subtract x / y-x: 2x / (y+x)(y-x) - x / y-x
Get: x(2-y-x) / (y+x)(y-x)
Simplify numerator : (2x - xy - x^2) / (y+x)(y-x)

Samantha plays a game in which she rolls two standard dice and finds the sum of the dots facing up. Which shows all the possible outcomes for each roll of the dice?
Answer:
Kindly check attached picture
Step-by-step explanation:
A standard dice has 6 faces numbered {1,2,3,4,5,6}
For 2 dice, n = 2 ; sample space = n² = 6² = 36
The sum of the 2 upward facing dots:
{(1,1) (1,2) (1,3) (1,4) (1,5) (1,6);
(2,1 ) (2,2),(2,3),(2,4),(2,5),(2,6) ;
(3,1)(3,2)(3,3)(3,4)(3,5)(3,6);
(4,1)(4,2)(4,3) (4,4)(4,5)(4,6);
(5,1)(5,2)(5,3)(5,4)(5,5)(5,6);
(6,1)(6,2)(6,3)(6,4)(6,5)(6,6)}
What should be subtracted from -8xy + 2x^2 + 3y^2 to get x^2 + 2
Answer:
x^2 - 8xy + 3y^2 - 2
Step-by-step explanation:
(-8xy + 2x^2 + 3y^2) - unknown = x^2 + 2
- unknown = x^2 + 2 + 8xy - 2x^2 - 3y^2
- unknown = -x^2 + 8xy - 3y^2 + 2
Unknown = x^2 - 8xy + 3y^2 - 2
Check:
(-8xy + 2x^2 + 3y^2) - (x^2 - 8xy + 3y^2 - 2)
= -8xy + 2x^2 + 3y^2 - x^2 + 8xy - 3y^2 + 2
= -8xy + 8xy + 2x^2 - x^2 + 3y^2 - 3y^2 + 2
= x^2 + 2

o figure out a special number, Tammi’s mother was supposed to double her age and then add 4. Instead, Tammi’s mother added 4 to her age and then doubled that number. Tammi’s mother thought the special number was 80. What was the special number supposed to be?
Answer:
40
her age was 36 she added 4nwhich made 40 then doubles makesn80
9514 1404 393
Answer:
76
Step-by-step explanation:
For age 'a', the special number was supposed to be ...
2a +4
Tammi's mother actually calculated it as ...
2(a +4) = 2a +8
a value that is (2a+8) -(2a+4) = 4 more than it was supposed to be.
The special number was supposed to be 80 -4 = 76.
harry purchased a 600$ savings bond if he has 1200 in total in the bank at the end of 10 years what was the simple interest rate
Answer:
R = 10%/year
Equation:
r = (1/t)(A/P - 1)
Solving our equation:
r = (1/10)((1200/600) - 1) = 0.1
r = 0.1
Converting r decimal to R a percentage
R = 0.1 * 100 = 10%/year
The interest rate required to get a total amount, principal plus interest, of $1,200.00 from simple interest on a principal of $600.00 over 10 years is 10% per year.
Step-by-step explanation:
so he has 600 $ saving then if he has 1,200 total in the bank
1x + 7 = 9x + 2 what is x
