Answer:
Step-by-step explanation:
4:12= 1:3
33 photos in a 4x to 7x ratio
4x + 7x = 33
11x = 33
x = 3
33 photos can be put in a 4(3) to 7(3) ratio
which is a 12 to 21 ratio
so 12 photos on one side, and 21 on the other side to get the ratio of 4 to 7

Answer: 1875km 840m
Step-by-step explanation:
From the question, we are informed that Gupty travelled 75km 800m by car and travelled 1800km 40m by aeroplane.
The distance that she travel altogether will then be:
= 75km 800m + 1800km 40m
= 1875km 840m
Answer:
The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.
Step-by-step explanation:
We are given the following information in the question:
A spherical balloon is designed to pop at the instant its radius has reached 3 centimeters.
The balloon is filled with helium at a rate of 10 cubic centimeters per second .

We have to find fast the radius is growing at the instant it pops.
Volume of spherical balloons =

Differentiating, we get,

Putting the values, we get,

The radius is growing at the rate of 0.09 centimeter per second at the instant it pops.
We let C be the cost
x be the number of loaves
cost = overhead cost+ cost to bake - selling price
cost = 90 + 0.60x - 1.50x
cost = 90 - 0.90x
