Answer:
A.
Using the given formula, the calculated surface area would be in cubic units instead of square units.
Step-by-step explanation:
64 divided by 16= 4
3x4=12
if Mckenzie uses 64 tea bags she will need to use 12 cups of sugar
Answer:
The correct option is;
C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2
Step-by-step explanation:
The area of the square frame is the area of the inner square subtracted from the area of the outer square
Which gives;
52.2² - 47.8² = 440
Therefore;
Option A. 52.2² - 47.8² is a correct way of finding the area of the square frame
Option B. 2 × ((52.2×2.2) + (47.8×2.2)) = 440, is a correct way of finding the area of the square frame
Option C. 52.2 × 4.4 × 2 + 47.8 × 4.4 × 2 = 880, is not a correct way of finding the area of the square frame
The error is the thickness is 2.2 not 4.4
Option D. 100×(52.2 - 47.8) = (52.2 + 47.8) × (52.2 - 47.8) = 52.2² - 47.8² = 440, is a correct way of finding the area of the square frame
Answer:
8 cups of water : 1 cup of cleaner
Step-by-step explanation:
To find the ratio, divide one value by the other. 12÷1½=8, so the ratio is 8 cups of water : 1 cup of cleaner.
2x - 3y < 12
-3y < -2x + 12...change the inequality sign because ur dividing by a negative number
y > 2/3x - 4
u have a slope of 2/3.....u have a y intercept of -4 or (0,-4)
to find the x int, sub in 0 for y and solve for x....disregard the inequality sign ....
y = 2/3x - 4
0 = 2/3x - 4
-2/3x = -4
x = -4 / (-2/3)
x = -4 * -3/2
x = 12/6
x = 2......and ur x int is 2 or (2,0)
so go ahead and plot ur intercepts (0,-4) and (2,0)....so start at (0,-4)...and since u have a slope of 2/3......go up 2 spaces and to the right 3 spaces...plot that point....then up 2 and to the right 3...plot that point...keep doing this and u will cross the x axis at (2,0)......now just draw a dashed line connecting ur plotted points
ur line will be a dashed line (because there is no equal sign in the problem)....ur shading will be above the line because it is greater then
