19 Students
basically I learned this trick at school, you take the percent, in this case it’s 95/100 and then you write it next to the fraction of what your unit is, so x/20 students
then you multiply 95 and 20 then divide by 100.
convert both dimensions to feet
1 mile = 5280 feet so 1/2 mile = 5280/2 = 2640 ft
1 yard = 3 ft so 600 yards = 600*3 = 1800 feet
now calculate area = 2640*1800 = 4752000 square feet
acres = square feet / 43560 so 475200/43560 = 109.09 acres
Answer:
[ 0 ]
Step-by-step explanation:
The order of the matrix [ 3 1 1 ] is 1 by 3 and the order of the other matrix is 3 by 1 so this means that the order of the answer matrix is 1 by 1. So we multiply matrices row by columns.
[ 3 1 1 ] × | 2|
| -6|
| 0|
[ 3 × 2 + 1 × -6 + 1 × 0 ]
[ 6 - 6 + 0 ]
[ 0 ]
Answer:
8
Step-by-step explanation:
Here, we want to use the inequality to know the number of pizza that can be bought
We simply proceed to solve the inequality recently and we have the following;
9.25x + 25 ≤ 105
9.25x ≤ 105-25
9.25x ≤ 80
x ≤ 80/9
x ≤ 8.65
Since we cannot have fractional pizzas, what he can afford is rather written as 8
