Answers

Answer 1

Answer:

The percentage of newborns who were boys is 65.71%.

Given that

At a local hospital, 35 babies were born.

There are 23 were boys.

We have to determine

What percentage of the newborns were boys?

According to the question

At a local hospital, 35 babies were born.

There are 23 were boys.

Then,

The percentage of the newborns were boys is determined by,

$\rm Percentage \ of \ new \ born \ boys = (Total \ number\ of \ boys * 100)/(Total \ number \ of \ babies)$

Substitute all the values in the formula.

$\rm Percentage \ of \ new \ born \ boys = (Total \ number\ of \ boys * 100)/(Total \ number \ of \ babies)\n\n\rm Percentage \ of \ new \ born \ boys = (23 * 100)/(35)\n\n\rm Percentage \ of \ new \ born \ boys = (2300)/(35)\n\n\rm Percentage \ of \ new \ born \ boys = 65.71 \ percent$

Hence, the percentage of newborns who were boys is 65.71%.

Answer 2

Answer: so the fraction would be 23/35 are boys. If you do the division (23 ÷ 35) the answer is around 0.657.

That converted into a percentage (×100) is 65.7%

The sides of a square are 2^4/9 inches long. what is the area of the square?A. 2^16/81 square inches
B. 4^16/81 square inches
C. 2^8/9 square inches
D. 4^8/9 square inches

Answers

The area of a square is the length of a side times itself:
2_4/9 * 2_4/9
Mixed numbers cannot be multiplied, so first convert to improper fractions:
(9*2)+4 = 18+4 = 22/9
22/9 * 22/9
Multiply straight across:
(22*22)/(9*9) = 484/81
Now turn this into a mixed number:
81 goes into 484 five times with 79 left over:
5_79/81 square inches
Since this is not one of the answer choices, I'm wondering if the given length of the side of the square is incorrect?

F(x) 5,450(1.024)^x The domain for the function that represents the amount of time the money will be in the college fund is _ the range for the function that represents the amount of money that is in the college fund is _

Answers

Answer:

1.) Domain X = all positive real numbers

2.) Range: F(x) > = 5450

Step-by-step explanation:

Given that

F(x) = 5,450(1.024)^x

Where the domain is the independent variable X and the range is the dependent variable Y or F(x)

Since the domain for the function represents the amount of time the money will be in the college fund, time cannot be negative, it will always be positive.

Therefore, domain x will be all positive real numbers.

The least domain x = 0

Substituting domain into the equation will give us a range of value:

F(x) = 5450 × ( 1.024 )^0

F(x) = 5450 × 1

F(x) = 5450

That is, the least value of range = 5450

Therefore, Range will be F(x) greater than or equal to 5450.

F(x) > = 5450

Write an equation to express the value of h + k

Answers

so since, they are the same distance from zero, they should be the oppposite of each other so in other words, k=-h and h=-k

so k+h=(subisute)k-k=-h+h=0 because they cancel

The answer you want is 0, let's say h=-1 that means k=1 so -1+1=0
