Answer:
14,334 actually that might not be the answer im just thinking that because the 4 is in the tenths place and ur rounding that u would make it into a whole number
27.5% of x=11 x is the number of people 27.5%=.275 x=11/.275=40 people in the survey participated
Length of one edge is 10cm
And the surface area is 600cm2
Answer:
A for first one and C
Step-by-step explanation:
Given that Macy wants to construct an isosceles triangle, with the unique angle being 40° it implies that for the triangle to be isosceles, the base angles should be the same. The size of the base angles will be:
(180-40)/2=70
given that that the base is 6 cm, Macy can only form 1 triangle with these dimensions.
The length of the other sides will be found using sine rule
a/sin A=b/sin B
a=6 cm
A=40°
b=?
B=70
hence:
6/sin 40=b/sin 70
b=(6sin 70)/sin40
b=8.77 cm
