Answer:
4 hours
Step-by-step explanation:
f the circumference of the circular garden =63 yards
Circumference of a Circle =2πr=πd (d=diameter)
Therefore:
πd= 63
diameter of the circular garden =63/3.14=20 yards
If he digs at a rate of 5 yards per hour, the time required to dig across the garden will be:
20 yards/5 yard per hours = 4 hours
It will take him 4 hours to dig across the circular garden.
Answer:
1. 40.00 sq units
2. 37.5 sq units
Step-by-step explanation:
1. Given slant height as 3 and the square base side as 4,
-The surface area of a right squared pyramid is calculated by summing the areas of the 4 triangles and the square base:
Hence, the area of the square pyramid is 40.00 sq units
2. The surface area of a cube is equivalent to 6 times the side of one face.
-Given the dimension of the sides as 2.5, surface area is obtained as:
Hence, the surface area of the cube is 37.5 sq units
I am pretty sure it is 30. Hope it helps!!

multiply first equaiton by 2
2x+6y=10
add to second equiaotn
2x-2x+6y-6y=10-10
0=0
this is true so therfor they are the same equaiton
so solve
x+3y=5
3y=-x+5
y=-1/3x+5/3
subsituter values for x and get valuse for y
if x=2 then y=1
Given: in the previous year, the table shows the prices of various amount of maize bushels in the same store.
A diagram displays the number of x-axis bussels and the price of maize in y axis dollars for 2012.
Search: The rate of change in this year's maize bushel, Part B: How many dollars is the present year's price of a maize bushel higher than in the previous year's maize bushel
Finding:
Earlier Year Panel
Bushel Number Corn prices
Shift rate of the previous year's maize bushel = (20-10)/(4 – 2) = = 10/2 = 5 Graph 2, 14, 4, 28, 6, 42 and 8, 56 and 10, 70, and 12, 84 Current year This year's rate of adjustment of the maize bushel, = (28 - 14)/(4 -2) = 14/2 = 7 7 - 5= 2 USD is more than the price of the maize bushel in the current year than the pre-year price of the maize bushel.
