Answer:
<em>£</em><em>1</em><em>9</em>
Step-by-step explanation:
Cheryl = 7 + 5 = £12
this means ova and eva also have £12 at the end
EVA'S ORIGINAL AMOUNT : X -7 =12
X = £19
Answer:
Initial value = 4
Growth factor = 1.6
Step-by-step explanation:
Function representing the exponential growth is given by,
f(x) = Initial value(1 + growth rate)ˣ
Here x = time or duration for growth
(1 + growth rate) = Growth factor
Given function is,
f(x) = 4(1.6)ˣ
By comparing both the functions,
Initial value = 4
Growth factor = 1.6
Answer:
Area = 960 cm^2
Step-by-step explanation:
Perimeter (P) = 2 (l + w)
P = 2l + 2w
Let the length be 5x
Let the width be 3x
From the question, P = 128.
Therefore:
128 = 2l + 2w
Divide both sides by 2.
l + w = 64
Recall we said:
l = 5x
w = 3x
So then:
5x + 3x = 64
8x = 64
Divide both sides by 8
x = 64/8
x = 8.
Since x = 8
Length = 5x = 5*8 = 40cm
Width =3x = 3 * 8 = 24cm
Area of a RECTANGLE:
Area = length * width
Area = 40 * 24
Area = 960 cm^2
Answer:
sin 60 = opp/hyp = f/(6√2)
f = 6✓2 × sin 60 = 6✓2 × (✓3/2)
= 3✓6
Answer:
y = 3/4x + 6
Step-by-step explanation:
6-3 3
------- = ------
0--4 4
y = mx + b
take coordinates for y and x out of (-4, 3) or (0,6)
6= 3/4 * 0 + b
6 = 0 + b
b = 6
