We have on the top of the figure one semircle, on the bottom of the figure another semicircle, to the left of the figure a line segment, and to the right of the figure another line segment, then we have a total of two semicircles and two line segments.
Answer: Fourth option: two semicircles and two line segments
Answer:
a. 10
b. -4
Step-by-step explanation:
For these problems, since we are given the x, we plug it into the expression and solve.
a.
3(4)-2 [multiply]
12-2 [subtract]
10
-------------------------------------------------------------------------------------------------------
b.
5(-2)+6 [multiply]
-10+6 [subtract]
-4
Answer:
The equal amount is 525
.
Step-by-step explanation:
Given that,
Eric and his two sister shared amount of money in ratio2:7 respectively.
Amount with Eric = 300
It means,
2x = 300
x = 150
So,
7x = 7(150)
= 1050
As the remaining amount shared equally among the sister. So, the equal amount is 525
.
Answer:
finding the number of equal-sized parts into which a number can be split
Step-by-step explanation:
Let us split the number 80 into 10 equal parts.
80 = 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8 + 8
= 8 + 8 + 8 +...to 10 times
= 8(10)
or 
So, if N is any number and p is one of its equal part, then the number of parts into which N is split by p is 
.
Hence, finding the number of equal-sized parts is best modeled with a division expression.
Medida do angulo central = medida do arco interceptado
arco = 25º e ângulo central = 25º
