Answer:
125
Step-by-step explanation:
we have
x*.28= 35
we divide both sides by .28 and get
x= 125
and 28% of 125 = 35
Hope it helps !
Answer:
x = 30 in
Step-by-step explanation:
length of rectangle is (2/3)x + 10; width is (1/3)x + 5;
perimeter is 90 in; find x:
P = 90 in = 2(2/3)x + 2(10) + 2(1/3)x + 2(5), or
90 in = (6/3)x + 30 in
Solving for x, we get (2)x = 60 in, or x = 30 in
Answer:
8.0
Step-by-step explanation:
Sin theta = opposite /hypotenuse
sin 53 = x/10
Multiply each side by 10
10 sin 53 = x
7.9863551
To the nearest tenth
x = 8.0
Answer:
133,787 residents
Step-by-step explanation:
First thing we need to do here is calculate the number of 5 years between 2020 and 1990
That would be 2020-1990 = 30/5 = 6
Now to estimate the present population, we will be needing an exponential equation
P = I(1-r)^n
where P is the present population at 2020
I is the population at 1990 which is 182,000
r is the percentage decrease every 5 years which is 5% or simply 5/100 = 0.05
n is the number of 5 years between 1990 and 2020 which is 6
Plugging all these values we have;
P = 182000(1-0.05)^6
P = 182000(0.95)^6
P = 133,786.724
To the nearest whole number, P = 133,787 residents
