Answer:
B ) c = 0.65n
Step-by-step explanation:
To find how much a single pound costs, divide the total cost by the total weight (2.60 ÷ 4). So, the cost (c), equals $0.65 per pound.
A child wants to fill up a box with snow he can only carry the box if it weighs under 30 pounds the dimensions of the box are 30in by 24 inches by 24 inches each cubic inch of snow weighs .004 pounds if the child fills the box entirely with snow will he be able to carry the box?
Answer:
As a rule of thumb, snow weighs approximately 20 pounds per cubic foot, or 1.25 pounds per inch of depth. Depending on moisture content, snow can weigh from 1 pound per cubic foot to over 21 pounds per cubic foot. NOTE: Any ice build-up on the roof would need to be added to this formula.

If b=10, evaluate 40/b A. b=10 B. b=30 C. b=2 D. b=4
Answer:
d
Step-by-step explanation:
substitute b for 10. you get 40/10. Now simplify it down. 20/5, which simplifies again to 4/1. 4 divided by 1 equals 4, which makes d true. hope this helps

A rectangle is covered by 24 unit squares. There are no gaps or overlap.
How can the area of the rectangle be found?
The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.
The area of the rectangle is half the number of unit squares that cover the rectangle. The area of the rectangle is 12 square units.
The area of the rectangle is double the number of unit squares that cover the rectangle. The area of the rectangle is 48 square units.
Answer: Choice A
The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.
=====================================================
Explanation:
Imagine drawing equally spaced grid lines to subdivide the rectangle. This splits the rectangle into smaller squares. In this case, each little square is 1 square unit. Having 24 of these squares leads to a total area of 24 square units.
We could have 8 rows and 3 columns of these squares to get 8*3 = 24 total. Or we could have 6 rows and 4 columns to get 6*4 = 24. Another configuration is 12 rows and 2 columns which leads to 12*2 = 24.

The expanded form of the expression y(0.25 +5) is 0.25y + 5y.
What are GCF and distributive property?The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.
We also know that distributive property states a(b + c) = ab + ac.
Expanded form or Distributive properties are the same in mathematics.
Given, An expression y(0.25 + 5).
So, applying distributive property a(b + c) = ab + ac to y(0.25 + 5) we have
0.25y + 5y.
= 5.25y.

Answer:
a) The acceleration between 20 and 40 seconds is equal to the slope in that range.
Remember that for aline that passes through the points (a, b) and (c, d) the slope is:
slope = (d - b)/(c - a)
In this case we can see the points:
(20s, 2m/s) and (40s, 4m/s)
Then the slope (and thus the acceleration) is:
slope = (4m/s - 2m/s)/(40s - 20s) = (2m/s/20s) = 0.1 m/s^2
The acceleration between 20 seconds and 40 seconds is 0.1 m/s^2
b) The total distance travelled is equal to the area under the curve.
So we could just count the number of squares, this is the easy way.
We can see that each square measures 10 seconds by 1 m/s, then the "area" of each square represents:
a = (10s)*(1m/s) = 10m
This means that each square represents a distance of 10 meters.
We can count that:
between 0s and 10s we have 1 whole square.
between 10s and 20s we have 2 whole squares.
between 20s and 30s we have 2 and half squares.
between 30s and 40s we have 3 and half squares.
Then the total number of squares under the curve is:
1 + 2 + 2.5 + 3.5 = 3 + 2.5 + 3.5 = 3 + 6 = 9
So we have 9 whole squares under the curve, and each square represents a distance of 10 meters, so the total distance traveled is:
Distance = 9*10m = 90m
c) We have an isosceles triangle where we know that one side measures 8.2 cm and another side measures 9.4cm
An isosceles triangle has two equal sides and one different.
So if we want to have the maximum perimeter, the two equal sides must have the longest side length (9.4 cm)
Then the (largest) perimeter of the triangle (the sum of the lengths of all 3 sides) is:
8.2cm + 9.4cm + 9.4cm = 27cm

Shown is a square garden with a triangular pond.
Find the area of the garden that is grass
The area of the garden that is grass is 30 square meters.
The square garden has a side length of 6 meters.
The triangular pond has a base of 4 meters and a height of 3 meters.
The area of the garden that is grass.
The area of the square garden is 6 x 6 = 36 square meters.
The area of the triangular pond is (1/2) x 4 x 3 = 6 square meters.
Therefore, the area of the garden that is grass is 36 - 6 = 30 square meters.
The area of the garden that is grass is 30 square meters.
Here are the steps in detail:
Calculate the area of the square garden: 6 m * 6 m = 36 square meters
Calculate the area of the triangular pond: (1/2) * 4 m * 3 m = 6 square meters
Subtract the area of the pond from the area of the square to find the area of the grass: 36 square meters - 6 square meters = 30 square meters
