Answer:
The number of bags used is 2 bags
Step-by-step explanation:
The mass of the jellybeans in the jar = 2 lbs
The mass divided evenly into bags = 1 pound each
Therefore the operation applied to the jar of jellybean is a division by 1 lb/bag, therefore, we have;
The number of bags used = 2 lbs/(1 lb/bag) = 2 bags
Answer:
The loan was for 9 months only
Step-by-step explanation:
In this question, we are concerned with calculating the time taken for a loan om an interest to be paid back
To calculate this, we use the simple interest formula
Mathematically;
I = PRT/100
where P is the principal which is the amount borrowed and that is $500 according to the question
R is the rate which is 8% according to the question
Interest can be calculated by subtracting the principal from the amount paid back = 530-500 = 30$
We now plug these values into the equation
30 = (500 × 8× T)/100
100 × 30 = 4000T
T = 3000/4000
T = 0.75 (same as 0.75 × 12 months = 9 months)
The pyramid is shown in the diagram below.
The pyramid is built from four congruent triangles and one square as the base
We have the side of the square, so the area is = 10×10 = 100
We need the height of the triangle to work out its area. We can find out by using the height of the pyramid and half of the length of the side of the square.
Using the Pythagoras rule
Height of triangle =

Area of one triangle = 1/2×10×12=60
Surface area of the pyramid = 100 + (4×60) = 340 square inches
Answer:
rule is when x increases by 1, y decreases by 3000
Step-by-step explanation:
Step-by-step explanation:
Cost per pound, c = 25cents
number of cans per pound, n = 100/4 = 25cans
total cans collected, t = 330cans
payment for total cans collected,p
where p = (t/n)×c = (330/25)×25 = 330cents
