Answer:
Step-by-step explanation:
∠1 = ∠2 = 70 {Corresponding angles}
2x +2 y = ∠1
2x + 2y = 70 --------------(I)
2x + y = ∠2
2x +y = 70 --------------(II)
Subtract equation (II) from (I)
(I) 2x + 2y = 70
(II) 2x + y = 70
<u>- - - </u> {subtract}
y = 0
Plugin y= 0 in equation(I)
2x + 0 = 70
2x = 70
x = 70/2
x = 35
x = 35 ; y = 0
Answer: c
Step-by-step explanation: 54% of people with internet access prefer text messaging, while only 31% of people without internet access prefer text messaging.
There should be 50 displays about nuclear power
30% of 150 is 45
45+25=70
.2% or 20% of 150 is 30
70+30=100
So there are 50 left over which are the nuclear powers
Answer:
(a)Initial Value: $29,900
(b)Value after 12 years: $1516.37
Explanation:
Given the dollar value v(t) of a certain car model that is t years old as:
(a)Initial Value
At initial value, that is, when the car was just purchased, t=0
The initial value of the car is $29,900.
(b)The value after 12 years.
When t=12
The value of the car after 12 years is $1516.37.
