Answer:
- yes
- no
Step-by-step explanation:
When a number of similar calculations are required, a spreadsheet can reduce the tedium.
1. The price is a constant $1.88 per pound, so is proportional to the weight.
_____
2. The price is not proportional to the number of toppings.
__
The cost of the pizza is $8.99 plus $1.50 per topping. The base cost being non-zero ensures that the overall cost is not proportional to the number of toppings.
Answer:
parallel = same slope (-2x)
so it's y=-2x + b
let's find b by plugging in 1 for x and 3 for y (the coordinates)
3 = -2*1 + b
3 = -2 + b
5 = b
there you have it:
y = -2x +5
brainliest would really be appropriated (possible when someone else also leaves an answer)
its the first one
Step-by-step explanation:
because per pertains to to x
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
Volume of A= πR².H ==> V(A)=4π m³
Volume of V =πR².H ==>V(B)=8π m³
.Ratio of A to B =(4π) /(4π) = 1/2
