1) Ratio - 4:1
thus, 4x + 1x = 20
5x = 20
thus, x = 20/5 = 4
thus, x = 4
and, 4x = 16
Thus, the answer is (C) 16 boys and 4 girls
2) According to distributivity, a(b+c) = ab + ac
Thus, the answer is (C)
Creditworthiness is the answer
Answer:
Step-by-step explanation:
200(1+r)⁵⁻³ = 200(1+r)² = 800
(1+r)² = 4
1+r = 2
r = 100%
800(1+r)⁷⁻⁵ = 800·2² = 3200
Answer:
The exponential equation is;
y = 0.1•0.5^x
Step-by-step explanation:
Here, we want to get the exponential function represented by the table
Mathematically, the general form of an exponential function is;
y = a•b^x
By getting a and b, we have the exponential function
We can use any of the points;
Let us start with (0,0.1)
0.1 = a•b^0
anything raised to zero is 1
0.1 = a * 1
a = 0.1
Now, we have a
Let us work with the second point to get b
The point is (1,0.05)
0.05 = 0.1•b^1
0.05 = 0.1b
b = 0.05/0.1
b = 0.5
Thus, we have the equation as;
y = 0.1•0.5^x
Answer:
x=32
Step-by-step explanation:
UVT is 90 degrees and a circle is 180 degrees so...
(180-90)-55=35
35-3=32
Answer: x=32
