Answer:
a = 14.19 feet
Step-by-step explanation:
Given that,
The area of a square shaped yard is 201.5 ft²
We need to find the side length of this yard in feet.
The area of a square shaped object is given by :
A = a², a is the side length of the object
Put A = 201.5 ft² in above formula,
So, the side of the square yard is 14.19 feet.
Answer:
The answer would be C because b=+16 which means that it intercepts line y at 16, which is shown in the graph.
Step-by-step explanation:
The sum of a geometric sequence is:
s(n)=a(1-r^n)/(1-r) in our case:
s(n)=3(1-4^n)/(1-4)
s(n)=-(1-4^n)
s(n)=(4^n)-1 and s=1023
(4^n)-1=1023
4^n=1024
n ln4=ln1024
n=(ln1024)/(ln4)
n=5
You are given the X value, replace x with 2 in the first equation to solve for y:
y=2x +3
y = 2(2) +3
y = 4+3
y = 7
Now replace y with 7 and x iwth 2 in the second equation and solve for k:
y = -x +k
7 = -2 +k
Add 2 to both sides:
9 = k
so k = 9
The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.
K = 9
Answer:
- 45 large candles
- 53 small candles
Step-by-step explanation:
Let c represent the number of large candles Jane sold. Then 98-c is the number of small candles. Her revenue is ...
8c +5(98-c) = 625
3c + 490 = 625 . . . . . . eliminate parentheses, collect terms
3c = 135 . . . . . . . . . . . . subtract 490
c = 45 . . . . . . . . . . . . . . divide by 3
Jane sold 45 large candles and 98-45 = 53 small candles.
