Answer:
0.4444444
Step-by-step explanation:
2/3 x 2/3 = 0.4444 repeating!
Hope this helps!
There are five parts to the ratio:
18 ÷ 5 is 3.6.
Therefore you need 10.8l of white paint and 7.2l of blue paint.
10.8l * 2.80 = £30.24
7.2l * 3.50 = £25.20
The total is <span>£55.44</span>
Answer:
x/3= $12.85
Step-by-step explanation:
x/3= $12.85
multiply 3 on both sides to get x= $38.55
Answer: 2,125,764
Step-by-step explanation:
You can use the equation y=ar^n-1 to find the 13th term where a is the starting term, r is the common ratio, and n is the nth term
The next number is 12/4=3 times greater than the first. So if this sequence is a geometric one, then the next term must be 12*3=36. This is true, and the next term must be 36*3=108, which is also true. Therefore this sequence is a geometric one and its common ratio is 3. Therefore the equation is:
y=4*3^(n-1)
Substitute 13 for n:
y=4*3^(13-1)
y=4*3^12
y=2125764
Therefore, the 13th term of this geometric sequence is 2,125,764
Answer:
Explanation:
The given points are:
- (0, 275)
- (1, 220)
- (2, 165)
- (3, 110)
- (4,55)
- (5, 0)
Since a <em>straight line joins</em> all the points, the equation that models the <em>relationship</em> is linear and you can find the slope-intercept equation which has the general form:
Where:
is the slope
is the y-intercept
<u>1. Find the slope</u>
You can use any two ordered pairs.
- m = rise/run = Δy/Δx = [220 - 275] /[1 - 0] = - 55
<u>2. Find the y-intercept</u>
The y-intercept is the value of y when x = 0; thus it is 275.
<u>3. Substitute in the slope-intercept equation</u>
That is the last option.
