Chris mixes 4 cups of cereal 3 cups of pecans and 2 cups of raisins. What are three ways to write the ratio of cups of cereal to cups of pecans?
1. 4 : 3 = 2 : 1.5
2. 2 : 4 = 3 : 6
3. 3 : 2 = 4 : 2.6
the quantity of x plus 16 all over 3 = 3x
Answer:x= 2
Step-by-step explanation:
X+16/3= 3x
3(x+16/3)=3(3x) [in order to cancel out the divided by 3]
X+16=9x
16=8x
2=x

m - n divided by 4 = - 3 /
Answer:
3
Step-by-step explanation:
PEMDAS means we divide first, and 8/4 is 2
then, we do the subtraction of 5 - 2, which is 3
Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answer: $84
Step-by-step explanation:
Price of smoke detector in Store A = $17
Price of smoke detector in Store B = $24
Total detectors bought = 12
Price of 12 detectors in Store A = $17 x 12 = $204
Price of 12 detectors in Store B = $24 x 12 = $ 288
Difference = $ 288 -$ 204 = $84
Hence, he will spend $84 less than if he purchased all the smoke detectors at Store B.

Step-by-step explanation:
Volunteers at the food bank package meals to feed a family of four. The table shows
the weight and serving size of each food. Each box can hold a maximum of 2,75
pounds, or 44 ounces.
Main Course
Side Dish
Food Serves Weight Food Serves Weight
Roast beef 4
16 OZ
Potato
1
3.8 oz
Chicken
2 12.6 oz Coleslaw
12.4 oz
Vegetable
42.6 OZ
Green salad
5.6 oz
bean soup
Lasagna
28 OZ
Baked beans 4 14.2 oz
Chill
8.6 oz Pasta
2. 5.2 oz
/point) 1: The food bank has 110.9 pounds or 1,774.4 ounces of chicken. To the
nearest
whole number, how many servings of chicken does this provide? Show your work
Answer:
The total number of servings of chicken the food bank can provide = 70 servings
Step-by-step explanation:
The given information from the table are;
The number of chicken contained in the main course of a serving of food = 2
The mass of each chicken served by the food bank = 12.6 oz
The quantity of chicken the food bank has = 110.9 pounds (1,774.4 ounces of chicken)
Therefore we have;
The mass of chicken per serving = 2 × 12.6 = 25.2 oz/serving
The total number of servings of chicken the food bank can provide = (The quantity of chicken the food bank has)/(The mass of chicken per serving)
∴ The total number of servings of chicken the food bank can provide = (1,774.4 oz)/(25.2 oz/serving) ≈ 70.413
Given that the servings are in whole numbers, we have;
The total number of servings of chicken the food bank can provide = 70 servings, to the nearest whole number.

The square shown is divided into five cells. Starting at any cell, how many paths can be drawn that move only to adjacent cells and that include all five cells?
Answer:
150 (not sure)
Step-by-step explanation:
Paths that only touch 5 points unrepeatedly:
I used a tree diagram to list all the workable paths, taking cell A as an example:
ABCDEABCEDABECDABEDCAEBCDAEDCBADCBEADCEBADEBCADECB2*(3x2 - 1) = 10
When you start at A you would have 3 choices, but after that only two, and since DB or BD can't happen and crossing B and D for the second step is the same, I double it.
Paths that touch 5 points and reapeat one of them:
2*(3x2x2 - 1x2) = 20
Paths that touch 5 points and repeat two of them:
2*(3x2x2x2-1x2x2) = 40
Paths that touch 5 points and repeat three of them:
2*(3x2x2x2x2-1x2x2x2) = 80
The sum of the answers in these 4 senarios is the final answer.

Step-by-step explanation:
first convert fraction to percentage, then into a decimal.
The line in a fraction that separates the numerator and denominator can be rewritten using the division symbol. So, to convert a fraction to a decimal, divide the numerator by the denominator. If required, you can use a calculator to do this. This will give us our answer as a decimal.

8x – 2 > -18
solve the inequality and graph the solution on the line provided.
Answer:
When solving inequalities you want to first group all like terms, so you'd first add 8 to both sides, and get rid of the extra number on the left side.
7x ≤ -7
Then you'd isolate the variable, so you should divide both sides by 7.
x ≤ -1
When graphing the equation the solution set includes -1 so you would put a closed circle (filled in). The variable "x" is less than and equal to -1 so you would put the arrow facing left <----.

If x varies directly as y, and x is 10 when y is 150, find the constant of variation. A. StartFraction 1 Over 150 EndFraction c. StartFraction 1 Over 15 EndFraction b. StartFraction 1 Over 1500 EndFraction d. One-fifth Please select the best answer from the choices provided A B C D
Answer:
c. StartFraction 1 Over 15EndFraction
= 1/15
Step-by-step explanation:
If x varies directly as y
This is expressed as:
x ∝ y
Constant of variation = k
Hence,
x = ky
To find k, divide both sides by y
x/y = ky/y
k = x / y
x is 10 when y is 150
Therefore,
k = 10/150
k = 1/15
Constant of variation = 1/15
Find the slope between the two points (1, -1) and (3, 7).
Answer:
the slope is 4
Step-by-step explanation:
You can solve this by using [tex]\frac{y2-y1}{x2-x1}[/tex] So in this case it's
[tex]\frac{7+1}{3-1}[/tex] due to the negative, you add instead of subtract. that becomes
[tex]\frac{8}{2}[/tex] Which is 4

Example of standard notation
45,000,000 ---> 4.5000000
Follow the example using the number 45,000,000. In this case, move the decimal point until it is after the first non-zero number. If moving to the left, go one additional space so that there is a whole number on the left and a mantissa on the right.
107⁷
The number of spaces the decimal point was moved becomes the exponent. If it was moved right, the exponent is negative. If left, the exponent is positive. If the exponent is zero, scientific notation isn't needed.
45,000,000 = 4.5 x 10⁷

Okay so I think by "standard notation" it means Regular notation/standard form so I'm answering in Regular notation/standard form. If I'm WRONG and It's asking for Scientific notation, tell me I can answer these in scientific notation also.

∠A and ∠ B ∠B are supplementary angles. If m ∠ A = ( 7 x + 15 ) ∘ ∠A=(7x+15) ∘ and m ∠ B = ( x + 13 ) ∘ ∠B=(x+13) ∘ , then find the measure of ∠ A ∠A.
Answer:
∠A = 148°
∠B = 32°
Step-by-step explanation:
We know that ∠A and ∠B are supplementary angles, this means that:
∠A + ∠B = 180°
And we also know that:
∠A = (7x + 15)°
∠B = (x + 13)°
Then we have a system of 3 equations.
To solve it, we can replace the second and third equations into the first one, and get:
(7x + 15)° + (x + 13)° = 180°
Now we can solve this for x, but first, let's remove the degree sign so it is easier to work:
7x + 15 + x + 13 = 180
(7 + 1)*x + 28 = 180
8*x = 180 - 28 = 152
x = 152/8 = 19
Now that we know x, we can find the values of ∠A and ∠B
∠A = (7x + 15)° = (7*19 + 15)° = 148°
∠B = (x + 13)° = (19 + 13)° = 32°
