Answer:
1/10 as a percent is 10%
1/5 as a percent is 20%
Step-by-step explanation:
You need to multiply the bottom numbers to 100 because usually all percentages are out of 100. The result is the top number.
Answer:
v . w= -13
Step-by-step explanation:
Evaluate the expression: v ⋅ w Given the vectors: r = <8, 1, -6>; v = <6, 7, -3>; w = <-7, 5, 2>
Solution
Given the vectors:
r = <8, 1, -6>
v = <6, 7, -3>
w = <-7, 5, 2>
If you're asking about the dot product.
The dot product is a scalar. It is the sum of the product of the corresponding components.
v.w = (6*-7) + (7*5) + (-3*2)
= -42+35-6
= -13.
Given :
Mo spends £15 on ingredients to make 40 cookies.
He sells all 40 cookies for 50p each.
To Find :
The Mo's percentage profit.
Solution :
We know, 1 £ = 66.09 p.
So, total income is :
T = 40 × 50 p
T = 2000 p
T = £2000/66.09
T = £30.26
So, total profit is, P = £( 30.26 - 15 ) = £15.26 .
Hence, this is the required solution.
Well if you buy only 1 of each, it would cost you 7.85 in total. if you subtract that from 20, it equals 12.15.
you can also make it a linear equation if you want more or less than 1 fruit and or sandwich
s=sandwich
f=fruit
5.7f+2.15f=20
