Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter
Answer:
a. 3 in.
Step-by-step explanation:
C = 6 π in
As you know circumference C= π d so d = 6
r = d/2 = 6/2 = 3
A° = 1/2 (90) = 45°
b° = 1/2[360 - (110 + 90)]
b° = 1/2(160)
b° = 80°
a° + b° = 45° + 80° = 135°
Answer
135°
Answer:
(x+3)(x+3)(x-4)
Step-by-step explanation:
I find a graphing calculator immensely helpful for factoring problems. Of course the constant in the binomial factor is the opposite of the x-intercept value. The x-intercept at -3 just touches the axis, so has even multiplicity. It will give rise to a repeated factor.
The x-intercepts of -3, -3 and +4 mean the factorization is ...
f(x) = (x +3)(x +3)(x -4)
