Answer:

33 2/3 %    (33.33%)

Step-by-step explanation:

Fraction = x/y

After decrease: (x - .5) / (y-.25)

Simplify :      .5x / .75y

                       = 2/3          

1 - 2/3 = 1/3 = .33 = 33 1/3 %

Hope this helps

A town has a population of 13,000 and grows at 5% every year what will the population be after 11 years to the nearest whole num
scoray [572]
This question is based on the concept of
amount of interest. Therefore, 22,234 would be
the population after 11 years, to the nearest
whole number.
Given:
A town has a population of 13000 and grows at
5% every year.
We need to determined the population after 11
years, to the nearest whole number.
We know that,
Formula =A = P(1+ r)
Where, p be the population. r is the rate and t is
the time.
P= 13000,
r= 5%
†= 11
Now put all these values in formula.
We get,
5
A = 13000(1 +
A
= 13000(1 + 0.05)11
A
= 1300022, 234.41(0.95)

The equation of circle having a diameter with endpoints (-2, 1) and (6, 7) is
densk [106]

Answer:

(x-2)^{2}+(y-4)^{2}=25

Step-by-step explanation:

step 1

Find the diameter of the circle

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

A(-2,1)\\B(6,7)  

substitute the values

d=\sqrt{(7-1)^{2}+(6+2)^{2}}

d=\sqrt{(6)^{2}+(8)^{2}}

d=\sqrt{100}

d=10\ units

The radius is half the diameter

so

r=10/2=5\ units

step 2

Find the center of the circle

the center of the circle is the midpoint between the endpoints of the diameter

so

The center is

(\frac{-2+6}{2},\frac{1+7}{2})

(2,4)

step 3

Find the equation of the circle

The equation of the circle is

(x-h)^{2}+(y-k)^{2}=r^{2}

substitute the values

(x-2)^{2}+(y-4)^{2}=5^{2}

(x-2)^{2}+(y-4)^{2}=25

Henry is making a recipe for biscuits. A recipe calls for 5/10 kilogram flour and 9/100 kilogram sugar.how much sugar and flour
Nonamiya [84]
So first find a common denominator which is 100 in this question. Then change 5/10 into a denominator of 100 which is 50/100 you don't have to change 9/100 because it has a denominator of 100. So then add the fractions and the answer is 59/100
