Answer:
1.5 per hour : 1.2 per hour
Step-by-step explanation:
The computation of the ratio is shown below:
For norma, the one pool would be
= 12 pools ÷ 8 hours
= 1.5 per hour
And for albert, the one pool would be
= 9 pools ÷ 7.5 hours
= 1.2 per hour
So the ratio between them is
1.5 per hour : 1.2 per hour
Given:
Jason buys three shirts with a listed price of $20 each.
He uses a coupon that provides "Buy Two, Get One Free".
To find:
The total final price Jason pays.
Solution:
Total number of shirts he buys = 3
Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.
Cost of 1 shirt = $20
Cost of 2 shirts = 2 × $20
= $40
Therefore, total final price Jason pays is $40.
Answer:
Look below.
Step-by-step explanation:
39.
10+ = 149 times x
3 - 9 = 143 times x
40.
2(w times 1.5 + w)
The question is not clear but I will solve it for all the possible conditions.
If cosФ = - √37 ÷ 6
Which means,
Adjacent = - √37
Hypotenuse = 6
This is not possible because hypotenuse cannot be smaller.
If cosecФ = - √37 ÷ 6
Which means,
Opposite = 6
Hypotenuse = - √37
Using Pythagoras theorem,
Adjacent = (Hypotenuse)² - (Opposite)²
Adjacent = √{(- √37)² - (6)²}
Adjacent = √{(37 - 36}
Adjacent = √{(1}
Adjacent = 1
Now we have all the three sides of a right triangle, therefore, we can find out the value for cotФ.
That is;
cotФ = adjacent ÷ opposite
cotФ =
