Answer:
176 tiles will be needed
Step-by-step explanation:
In this question, we are asked to calculate the number of tiles needed by Mrs Allen to rule the floor of her kitchen given that each of the tile has an area of 1 square feet and the kitchen is 11ft by 16 feet
To answer this question, firstly, we need to calculate the area of the whole floor .
since the floor is rectangular in shape according to the dimensions, the area of the floor of the kitchen would be L * B = 16 * 11 = 176 square feet
Now, each of the tiles to be fitted has an area of 1 square feet, this means that the number of tiles to be fitted will be the total area of the kitchen floor divided by the area of the individual tiles
That is 176/1 = 176
20 boys signed up
# of girls who signed up was 195% of the number of boys who signed up
Find 195% of 20:
1.95 * 20 = 39
So 39 girls signed up.
To find out what percent of girls who signed up for the play attended the auditions, divide 26 to the total number of girls who signed up:
26 / 39 = 0.666666667
Multiply by 100:
0.666666667 * 100 = 66.6666667%
So approximately 66.67% or 66 2/3%

of. <em>(</em><em>a-</em><em> </em><em>b</em><em>)</em><em>³</em>
A and B are complementary, that means m∠A+m∠B=90
Recall that sinA=cos(90-A), if sinA=8/9, cos(90-A) is also 8/9
therefore, cosB=cos(90-A)=sinA=8/9<span />
