Answer:
140 oranges
Step-by-step explanation:
From the Question, we know that the pyramid has 7 layers
The number of oranges in the first layer is = 1
Hence, the number of oranges in a pile is calculated as:
1² + 2² + 3² + 4² + 5² + 6² + 7²
= 1 + 4 + 9 + 16 + 25 + 36 + 49
= 140 oranges
46+34 = 80
62+51 = 113
80 + 113 = 193
Answer:
Step-by-step explanation:
Total she can make = 11
Amount she has already made = 3
Amount she still have to make = 11-3 = 8
% of the 20blanket she still have to make = 8/20×100
= 8×5
= 40%
Hence she Still need to make 40% of the 20blanket
Answer:
The southern lighthouse is 3.4 miles closer than the northern lighthouse
Step-by-step explanation:
From the figure we see that we need to find the distances AK and BK.
The measure of the third angle K is = 180- 25-35= 120 degrees
Using the sine ratios we can find the two distances
From the figure
The northern distance is given by
20/ sin 120 = kA/ sine 35
KA= 20 sine 35/ sine 120
KA= 13.25 miles
The southern distance is given by
20 /sine 120= KB / sine 25
20 sine 25/ sine 120 = KB
KB= 9.759=9.76 miles
Difference between the two miles =
13.25 miles - 9.76 miles = 3.49 miles
The southern lighthouse is 3.4 miles closer than the northern lighthouse
Option C is correct
The correct option that matches the graph is option A.
Graph is a fine representation of a network and it describes the relationship between lines and points. The length of the lines and position of the points don't count. Each object in a graph is called a knot.
The four introductory graphs used in statistics include bar, line, histogram and pie maps. The description of a graph is a illustration showing the connections between two or further effects. An illustration of graph is a pie map. noun. A wind or line showing a fine function or equation, generally drawn in a Cartesian match system.
Since it is upside down, it is the one with the negative sign in front of the x. The numbers will continue to increase in the negatives.

Hence, the equation on option A matches the graph.
