Answer:
b. 
Step-by-step explanation:
Here we are given 
and are asked to simplify it. We are going to apply the law of exponents which says that
Hence applying this rule in our problem we get, where a=y and n=3
Hence our C) Option is correct
Answer:
500 g flour = 600 g
6*1.2 g salt = 7.2 g
12*1.2 g yeast = 14.4 g
30 mL oil = 36 mL
360 mL water = 432 mL
Step-by-step explanation:
10 bread rolls requires 500g of flour.
Eli uses 600g of flour which is 1.2 times the amount needed for 10 bread rolls.
This means that 1.2 * 10 bread rolls are made which is 12 bread rolls.
Multiply the remaining ingredients by 1.2:
500 g flour = 600 g
6*1.2 g salt = 7.2 g
12*1.2 g yeast = 14.4 g
30 mL oil = 36 mL
360 mL water = 432 mL
Answer:
The equation of the line is 6y = 7x + 23
Step-by-step explanation:
We begin by calculating the slope of the line;
mathematically, the slope is given by;
m = (y2-y1)/(x2-x1)
That would be;
m= (5-(-2))/(1-(-5))
m = 7/6
So the equation becomes;
y = 7/6x + b
We below need to get the value of the y-intercept b
We get this by making a substitution for any of the two points
Let’s say we make the substitution for (-5,-2) in which case y = -2 and x = -5
Thus, we have
-2 = 7/6(-5) + b
-2 = -35/6 + b
b = -2 + 35/6
b = (-12+ 35)/6 = 23/6
So we have;
y = 7/6x + 23/6
let’s multiply through by 6
6y = 7x + 23
Answer:
-3/2
Step-by-step explanation:
here it goes. (-1)- (2) / (5)-(3)
Area tells us the size of a shape or figure. It tells us the size of squares, rectangles, circles, triangles, other polygons, or any enclosed figure.
In the real world it tells us the size of pieces of paper, computer screens, rooms in houses, baseball fields, towns, cities, countries, and so on. Knowing the area can be very important. Think of getting a new carpet fitted in a room in your home. Knowing the area of the room will help make sure that the carpet you buy is big enough without having too much left over.
Calculating Area
Area is measured in squares (or square units).
How many squares are in this rectangle?
example of rectangle with area of 15 square units
We can count the squares or we can take the length and width and use multiplication. The rectangle above has an area of 15 square units.
