Answer:
20 + 1 + 0.9 + 0.07
Step-by-step explanation:
Given the number 21.97 ;
To wite in expanded form:
Tens ___ Unit ____ tenth ____ hundredth
2_______ 1 _______ 9_________ 7
2 = 20
1 = 1
9 = 0.9
7 = 0.07
Hence,
20 + 1 + 0.9 + 0.07
<span>Simplifying
2x + n = 3
Reorder the terms:
n + 2x = 3
Solving
n + 2x = 3
Solving for variable 'n'.
Move all terms containing n to the left, all other terms to the right.
Add '-2x' to each side of the equation.
n + 2x + -2x = 3 + -2x
Combine like terms: 2x + -2x = 0
n + 0 = 3 + -2x
n = 3 + -2x
Simplifying
n = 3 + -2x</span>
F(x) = 8.
This is a constant function. No matter the value of x, f(x) will always be = 8
Therefore when x = 10, f(x) = 8.
The order you apply the adjustments does make a difference because the percents that are applied will be applied to different amount.
For example, 80% of 100 = $80. The price would be $180.
Decreasing this by 25% 25% of 180 = $45; 180-45 = $135.
25% of 100 is not the same as 25% of 180.
Answer:
372 inches
Step-by-step explanation:
(1 yd = 36 in., and 1 ft = 12 in.)
1 yard stick = 24 in
This means , height of 36 inches casts a shadow of 24 Inches
At the same time a telephone pole casts a shadow of 20 ft 8 in
1 ft = 12 in
Hence,
Convey 20ft to inches
1 ft = 12 in
20 ft = 20 × 12 inches
= 240 inches
Total shadow of the telephone pole = 240in + 8 in = 248 = 248 inches
Hence,
Height/Length of shadow = Height/Length of shadow
36/24= x /248
Cross Multiply
24 × x = 36× 248
x = 36 × 248/24
x = 372 inches
The height of the telephone pole, to the nearest inch is 372 inches
