Answer:
10p coins does he have 102
Step-by-step explanation:
given data
saves= 10p coins and 20p coins
total = 17 pounds
to find out
how 10p coins does he have
solution
we consider here no of 20p coin = x
so equation will be here
3 × 10 x +20 x = 1700
30 x + 20 x = 1700
x = 34
so that
10p coins = 3 time × 34 = 102
20p coins = 34
so that 10p coins does he have 102
Answer:
Volume of the similar sphere be 64 :343 .
Option (D) is correct.
Step-by-step explanation:
Formula

As given
The volumes of two similar spheres given that the ratio of their radii is 4:7 .
Let us assume that the x be the scalar multiple of the radi .
Radius of first sphere = 4x
Radius of second sphere = 7x
Putting the values in the formula




Thus


Therefore the ratio of the volume of the similar sphere be 64 :343 .
Option (D) is correct .
Answer:
B(x) is the better option
Step-by-step explanation:
Let's say that these functions represent the pay f(x) in hours, x. Function B would increase linearly on a greater scale because each X is being multiplied by 20.
You'll notice this trend for larger numbers, such as 10.
A(x) = 5(10) + 20 = 70
B(x) = 20(10) + 5 = 205
Therefore, your answer is B.
How to solve the equation Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
