Answer:
Send me a clarity question.
Answer:
Step-by-step explanation:
<u>Let the number be x</u>
- 380% of x is 99
- x*3.8 = 99
- x = 99/3.8
- x = 26 rounded to the nearest whole number
Given:
Right triangles:
To find:
The value of c and value of d
Solution:
<u>In the first right triangle:</u>
θ = 45°
Opposite side to θ = 5
Hypotenuse = c
The value of sin 45° =
Do cross multiplication, we get
<u>In the second right triangle:</u>
θ = 60°
Opposite side to θ = 4
Adjacent side to θ = d
Do cross multiplication, we get
The value of and .
Answer:
Roots (It has a solution)
Step-by-step explanation:
One method to find out whether or not this equation has a solution or not is to try to solve for x..
As we could find a solution, it has a root.
Answer:
1.5
Step-by-step explanation:
The sequence given is a geometric progression (G.P). For a G.P where the first term is a, the common ratio (which is the ratio between successive terms), the nth term of the GP is given as
Tn = ar^n-1
From the sequence given
a = 1536
r = 768/1536
= 1/2
= 0.5
Hence the 11th term of the sequence
T11 = 1536 (1/2)^11-1
= 1536 (1/2)^10
= 1536/1024
= 1.5
