Answer:
1/10
Step-by-step explanation:
(3/5) - (1/2)
3/5 = 3*2/ 5*2 = 6/10
1/2 = 1*5/ 2*5 = 5/10
(6/10) - (5/10)
= (6-5) / 10
= 1/10
Answer:
a. 80%
b. £34
c. £340
Step-by-step explanation:
a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.
b. 10% of Mrs Trent weekly wage:
If 20% = £68
10% = (10*68)/20 = £34
c. Let x represent weekly wage of Mrs Trent
Given that she spends £68 of x (weekly wage) on food, which is 20% of x.
This means that, 20% of x = £68
Let's find her weekly wage, x:


Divide both sides by 0.2
x = 340
Her weekly wage is £340.
Answer:
<em>550ft²</em>
Step-by-step explanation:
<em>Since we are not given the dimension of the rectangular prism. Let us assume;</em>
Length of the rectangular base L = 10ft
Width of the rectangular base W = 15ft
height of the prism H = 5ft
Total surface area of the prism = 2(LW + WH + LH)
Substitute the given values
Total surface area of the prism = 2{10*15 + 15*5 + 10*5}
Total surface area of the prism = 2(150+75+50)
Total surface area of the prism = 2(275)
<em>Total surface area of the prism = 550ft²</em>
Answer: x^2−xy+1
Step-by-step explanation:
simplify:
5+x^2−xy−4
5+x^2+−xy+−4
Combine Like Terms:
5+x^2+−xy+−4
(x^2)+(−xy)+(5+−4)
x^2+−xy+1
