The chart shows the sizes and prices of different sized boxes of Alex's favorite cereal.
Step-by-step explanation:
Compare the rates
Whichever has the smaller rate is the best deal.
remember, to be able to compare both cereal boxes they must have the same unit of measure (grams with grams, ounces with ounces, etc.)
Answer:
Price of box of cereal #1
---------------------------- = $ per ounce(or other unit)
Size of box #1 (in ounces,
or some other unit)

$ 350 is shared in the ratio 2:5. The SMALLER share is
Answer:
$100
Step-by-step explanation:
sum the parts of the ratio, 2 + 5 = 7 parts , then
$350 ÷ 7 = $50 ← value of 1 part of the ratio , then
2 parts = 2 × $50 = $100 ← smaller share

1) 1.7 ÷ 8.5
We need to change them to whole numbers by shifting the decimal points one place to the right to get; (17/85)
2) 50 ÷ 0.1
Shift decimal one place to the right to get;
500/1
Quotient = 500
3) 0.86 ÷ 0.02
The dividend is usually the numerator. Let us shift both numerator and denominator by two decimal places to the right to get; 86 ÷ 2
Thus, new dividend = 86
4) 6.9 ÷ 0.3
Move decimal points one place to the right to get;
69 ÷ 3 = 23
5) 75.64 ÷ 0.61
Move decimal points two places to the right to get;
7564 ÷ 61
Numerator written as a factor of denominator gives;
(124 × 61)/61
Quotient = 124
6) 7.26 ÷ 0.22
Move decimal points two places to the right to get;
726/22
Numerator written as a factor of denominator gives;
(33 × 22)/22 = 33
7) 5.12 ÷ 0.10
Move decimal points two places to the right to get;
512/10 = 51.2
8) A 0.75 m pink ribbon was cut into 0.25 m strips. Thus;
Number of pieces = 0.75/0.25
Move both decimals 2 places to the right to get;
75/25 = 3 pieces
9) A bottle contains 27.5 ounces
You take 1.65 ounces for each dose.
Number of doses per bottle = 27.5/1.65
Move decimal points two places to the right; 2750/165
Number of doses per bottle = 16.67 doses
10) She earned Php256.25 for gardening.
She worked 20.5 hours the month.
Amount earned per hour = 256.25/20.5
move decimal places two points to the right to get;
Amount earned per hour = Php 12.5
11) 5.26 times 10
move decimal place two points to the right to get;
(526 × 1/100) × 10 = 52.6
12) 59 ÷ 7
Nearest multiple of 7 to 59 is 8.
Thus, 59 ÷ 7 = 8³/₇
⇒ 8.43
13) The one that gives a quotient of 6.78 is;
61 ÷ 9
14) How many 7 does 86 have?
This is; 86 ÷ 7
Nearest multiple of 7 to 86 is 84 which is 12 × 7
Thus, there are 12 numbers of 7 in 86.
15) Remainder if you divide 59 by 9
Nearest multiple of 9 to 59 is 54 which is 9 × 6.
Remainder = 59 - 54 = 5
16) When divisor is bigger than the dividend, it means the denominator is bigger than the numerator and so the quotient is an improper fraction which is a decimal.
17) 4 ÷ 9 = 0.444
Approximating to one decimal place = 0.4
18) The correct mathematical sentence with never ending decimal is;
24 ÷ 27

the line passes through the point (6,1) and has a slope of -1/2 what is the point slope form and slope intercept form
Hi there! :)
We are given the slope of the line and a point that it passes through.
Using this information, we can write the equation in point-slope form:
y-y1=m(-x1)
y-1=-1/2(x-6)
y-1=-1/2x+3
Now, move -1 to the right, using the opposite operation:
y=-1/2x+3+1
y=-1/2x+4
And that's our equation. Hope it helps.

How do the 2s in 12.5 and 0.912 compare?
A The value of the 2 in 12.5 is 11,000 the value of the 2 in 0.912.
B The value of the 2 in 12.5 is 1100 the value of the 2 in 0.912.
C The value of the 2 in 12.5 is 10 times the value of the 2 in 0.912.
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912.
Answer:
D The value of the 2 in 12.5 is 1,000 times the value of the 2 in 0.912
Step-by-step explanation:
The value of a digit in a number can be found by setting the other digits to zero.
The value of 2 in 12.5 is 2.
The value of 2 in 0.912 is 0.002.
The ratio of values is 2.000/0.002 = 2000/2 = 1000.
The value of 2 in 12.5 is 1000 times the value of 2 in 0.912.

D
Step-by-step explanation:
The answer is D
In the figure, what would be represented by c^2
A the sum of the lengths of legs a + b
B the area of the rectangle with diagonal
c the length of the hypotenuse of the triangle
D the area of a square constructed on the hypotenuse
Answer:
D
Step-by-step explanation:
We can go through each answer to see if it's right
A
In a right triangle, with c opposite the right angle, we know that
a²+b² = c²
The answer is stating that a+b = c². Unless both a and b are either 0 or 1, this is incorrect
B
The area of a rectangle is equal to length * width, or in this case, a* b. Compare this with our equation of
a²+b² = c² and this is incorrect
C
The hypotenuse, or the side opposite the right angle, is c. The answer is stating that c = c². This is incorrect unless c = 1 or c = 0
D
The square constructed on the hypotenuse would have a side length of c. The area of a square is length², or in this case, c². c² = c² so this is correct

Step-by-step explanation:
Multiply the cost of the number of pairs of jeans by the sales tax amount, 7%.
cost of 2 pairs: 48 + 7/100 x 48 = $51.36
cost of 3 pairs: 72 + 7/100 x 72 = $77.04

0/35-31/35-2/35= Reduce if possible
Hi!
I will write it like this to make it easier to see:
[tex]\frac{0}{35} - \frac{31}{35} - \frac{2}{35}[/tex]
Seeing this, we can right away take the [tex]\frac{0}{35}[/tex] away to make it easier, because 0/35 is 0. Now, we are left with:
[tex]-\frac{31}{35} - \frac{2}{35}[/tex]
Since the denominators (the 35s) are the same, we do not have to mess with those. We simply subtract the numerators (-31 - 2) and we get -33. Therefore, your answer is :
[tex]-\frac{33}{35}[/tex]
Hope this helps! Have a great day! :D
What is the distance between (5,2) and (0, -2)
Step-by-step explanation:
the distance between 2 points can be seen as the Hypotenuse of a right-angled triangle with the legs being the x and y coordinate differences.
and so, we use Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
distance² = (5 - 0)² + (2 - -2)² = 5² + 4² = 25 + 16 = 41
so, the distance is sqrt(41) = 6.403124237...
Yesterday, there were 100 problems assigned for math homework. Pablo got 60 problems correct and 40 problems incorrect. What percentage did Pablo get correct?
(2x + 3y)^2– (2x – 3y)^2
Hi,
(2x + 3y)² - (2x - 3y)²
(a + b)² = a² + 2ab + b²(a - b)² = a² - 2ab + b²= [(2x)² + 2x*3y + (3y)²] - [(2x)² - 2x*3y + (3y)²]
= (4x² + 6xy + 9y²) - (4x² - 6xy + 9y²)
= 4x² + 6xy + 9y² - 4x² + 6xy - 9y²
= 12xy

a room that needs to be tiled is 12 1/2 feet wide by 14 feet long. tiles that mesure 2x2 are $0.79 per tile. Tiles that measure 3x3 are 1.25 per tile. which size tile should be used for this project to save the most money? How many tiles would be needed? How much would you spend on them? HELP PLEASE!
Answer:
Step-by-step explanation:
Area of the room is 12.5(14) = 175 ft²
2x2 tiles are 4 ft²
175 /4 = 43.75 tiles so 44 will be needed
44($0.79) = $34.76
3x3 tiles are 9ft²
175/9 = 19.4444... so 20 will be needed
20($1.25) = $25.00
the larger tiles will cost $9.24 less than the smaller tiles.
Obviously some of the tiles will need to be cut to fit as the length and width of the room are not always a uniform number of tiles for either side.
