Answer:
£15.7
Step-by-step explanation:
32 cans x 50P = 1600p
1600p to Pounds = £26.66 (1600 divided by 60)
Remaining cans = 18 (50 - 32)
18 cans x 20p = 360p
360p to Pounds = £6 (360 divided by 60)
£26.66 + £6 = £32.66
£32.66 (Profit) - £17 (Cost of cans) = £15.66
15.66 to 3SF = 15.7
Answer:
D) -122
Step-by-step explanation:
Given:
We need to find f(-4).
Now by substituting the value of x =-4 in above equation we get;
By using PEDMAS we will solve for exponential function first we get;
Now we know that 
So we get;
Now using PEDMAS we will solve division.
Now using PEDMAS we solve multiplication.
Finally by subtraction we get;
Answer:
20√3 cm
Step-by-step explanation:
Altitude of an equilateral triangle splits it into 2 equal right triangles, it bisects the base and the angle opposite to the base.
<u>Let the altitude be x. Then as per Pythagorean theorem:</u>
- x² = 40² - (40/2)²
- x²= 1600 -400
- x²= 1200
- x= √1200
- x= 20√3 cm
<u>Correct choice is</u> the second one
