Answer: Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
Step-by-step explanation:
Let x = number of slices
As per given,
Total monthly cost for x slices = (membership cost) +(discounted price) ×(x)
i.e. Total monthly cost for x slices = 5+1.5x
If x=20
Then, Nazim have to pay = 5+1.5(20)
= 5+30= $35
i..e Nazim have to pay $35 for 20 slices of pizza.
Monthly cost for x slices = 5+1.5x
300
divide 3000 by 10 to get a tenth of 3000
Answer:
65.4 cm²
Step-by-step explanation:
The volume of a cuboid is calculated by multiplying the length, base, and height together. Since a cube has equal sides, the formula for the volume of a cuboid can be simplified as shown below.
Volume of cube
= side ×side ×side
= side³
Given that the volume is 36 cm³, let's find the length of each side.
side³= 36
Cube root both sides:
side=![\sqrt[3]{36}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B36%7D)
Total surface area of a cube is the sum of the surface areas of its 6 identical square faces.
Area of a square
= side ×side
= side²
Surface area of 1 face= ![(\sqrt[3]{36})^2](https://tex.z-dn.net/?f=%28%5Csqrt%5B3%5D%7B36%7D%29%5E2)
Total surface area
= ![6(\sqrt[3]{36} )^2](https://tex.z-dn.net/?f=6%28%5Csqrt%5B3%5D%7B36%7D%20%29%5E2)
= 65.416 (5 s.f.)
= 65.4 cm² (nearest tenth)

Answer:
t = r + 11
Step-by-step explanation:
t - 5 = r + 6 ( add 5 to both sides )
t = r + 11
