Answer:
9/4
Step-by-step explanation:
(-3/2)^2=9/4
Step-by-step explanation:
A. this is a geometric sequence.
according to y-coordinates =>
3, 6, 12, 24
have a T1 = 3 and ratio = 6/3 = 2
B. the formula = Tn = r. T(n-1)
T5 = 2. T4
= 2. 24 = 48 minutes
C. the formula : Tn = T1 . r^(n-1)
T9 = 3. 2^(9-1)
= 3. 2^8
= 3. 256
= 768 munutes
Answer:
(x, y)=(4,-8)
Step-by-step explanation:
9x+y=28
3x+3y=-12 /:(-3)
9x+y=28.......(1)
-x-y=4......(2)
9x+y=28
(1)+(2): 8x=32
9x+y=28
x=32/8
9x+y=28
x=4
9*4+y=28
x=4
36+y=28
x=4
y=28-36
x=4
y=-8
x=4
(x, y) =(4,-8)
Answer:
$19.50 + $14.20x < $110
Step-by-step explanation:
only one pair of jeans and the rest shirts but it can also equal to $110
The weight of the circle that is double the weight of the triangle is 20 grams.
<h3>How to find weight ?</h3>
The weight of the rectangle is 80 grams.
The weight of the triangle is double the weight of the weight of the circle.
A rectangle is made up of 2 triangles. Therefore,
weight of each triangle = 80 / 2 = 40 grams
Since, the weight of the triangle is double the weight of the circle, the weight of the circle can be calculated as follows:
weight of circle = 40 / 2
Therefore,
weight of the circle = 20 grams.
