Answer:
B.
Step-by-step explanation:
Since we have a dotted line, our inequality must be either < or >, so A and D are out. We are left with B and C. Since our line is positive, our answer must be B and not C.
Alternatively, you can graph each equation and choose the best answer that matches the graph.
I believe that it’s the last one because it makes the most sence but then again i could be wrong
1) What is the slant height x of this square pyramid? Express your answer in radical form
sin 60=x/4--------> x=4*sin 60------> 4*(√3/2)-------> 2 √3 m
the answer Part 1) is 2 √3 m
2) The base of a regular pyramid is a hexagon. What is the area of the base of the pyramid?
[area of the base}=[area of hexagon]
[area of hexagon]=6*[area of triangle]
area of triangle
sin 60=a/14-------> a=(√3/2)*14-------> a=7√3 cm
cos 60=(b/2)/14--------> (b/2)=cos 60*14-----> (1/2)*14---------> (b/2)=7
base of triangle=2*7--------> b=14 cm
[area of triangle]=14*7√3 /2--------> 49√3 cm²
so
[area of hexagon]=6*[49√3]--------> 294√3 cm²
9 friends
23 2/5 bags of apples
23 2/5 = 23.4
23.4 / 9 = 2.6
each friend may take 2 3/5 bags
Answer:
Don is incorrect
Step-by-step explanation:
9 * 9 = 81
Even numbers are divisible by 2 but 81 is not.
Therefore, Don is incorrect in saying that 9*9 is an even number.
