Lets find the missing sides first
big triangle, we apply the Pythagorean theorem a^2+b^2=c^2
a^=13^2-5^=169-25=144, Square root of a=square root of 144=12
a=12
smaller triangle
5^2-3^2=b^2
25-16=9
b=4
Elm trail is 13km+5km=18km
Dogwood trail=12+5+4+3=24km
correct choices are 2 and 5
Answer:
25
Step-by-step explanation:
If one box of rice feeds 5 students, then 5 boxes of rice will feed: 5 x 5 = 25 students
There is a totaly of 50 students, and only enough rice for 25 students. Therefore, the number of students who will not get rice = 50 - 25 = 25
Answer:
Step-by-step explanation:
The line passes through the origin, so its equation is of the form;
The graph also passes through .
We substitute this point to obtain;
We divide both sides by 2 to get;
We substitute the value of m into the equation to get;
The correct answer is A
Answer:
98π cm²
Step-by-step explanation:
A circle is a plane figure. A circle is the locus of a point such that its distance from a given point is always constant.
We can see that both circle C and circle D are equal with a radius of 7 cm.
Area of circle C = π* radius² = π * 7² = 49π cm²
Area of circle D = π* radius² = π * 7² = 49π cm²
The sum of the areas of circle C and circle D = Area of circle C + Area of circle D = 49π + 49π = 98π cm²
Answer:
a=21060
Step-by-step explanation:
A= B*W*H
A=36*39*15
A=1404*15
A=21060
