Answer:
Figure 1:
Area: 30m^2
Perimeter: 23.6m
Figure 2:
Area: 98.8km^2
Perimeter:56.5km
Step-by-step explanation:
Area is base x height.
To get the perimeter, add up all the sides.
Figure 1:
Area:
6x5=30m^2
Perimeter: 6+5.8+6+5.8=23.6m
Figure 2:
Area:
7.6x13 = 98.8km^2
Perimeter:7.6+15+20+13.9=56.5km
The sum of the 9th square number and 3rd cube number is 108
Answer:
C, 15
Step-by-step explanation:
i looked it up
Nice, already in vertex form
y=a(x-h)^2+k
(h,k) is vertex
therfor since (-3,6) is vertex
we are looking for something like
y=a(x-(-3))^2+6 simplified to
y=a(x+3)^2+6
A is ansre
Answer: 77 seeds
Step-by-step explanation:
Given: The germination rate for zinnia seeds =78%
Let x be the total number of seeds he planted, then
The seeds germinated= 78% of x
⇒The seeds germinated= 0.78x
If James wants 60 zinnia plants for his yard, then it will give the equation

Hence, he should plant 77 seeds .
