30 points! The equation y=1.55x + 110,419 approximates the total amount, in dollars, spent by a household to raise a child in the United States from birth to 17 years, given the household’s annual income, x.



What is the approximate average yearly cost of raising a child in a household with an annual income of $33,000

Answer:

t=9.48n+119.88

Step-by-step explanation:

where t is the total cost of 12 t-shirts, and n is the number of words in the design

0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design

t=12(0.75n+9.99)

where t is the total cost of t-shirts, and n is the number of words in the design

When simplified, this becomes t=9.48n+119.88

Answer: 6(x+5)=y

Step-by-step explanation: This is because to represent two different factors (in this case, addition and multiplcation.), it is easier to put parenthesis around a part of that expression.

Answer:

Step-by-step explanation:

let the total number of students be x

45% of x is 135

that is

=(45/100)*x=135

0.45x=135

x= 135/0.45

x= 300students

Therefore the total number of students is 300

Step-by-step explanation:

Answer:

Part 1: 61 degrees Part 2: 90 degrees

Step-by-step explanation:

m<a = 180 - m<b - m<c - 29

m<c = 29

m<b = 90-29

m<b = 61

m<a = 180 - 61 -29 -29

m<a = 61 degrees

m<c + m<b = 29 + 61

m<c + m<b 90 degrees

Step-by-step explanation:

Answer:

4.9

Step-by-step explanation:

first step is to add up 44 and 77, to get 121

the goal is to get a value of 180 degrees, so taking the info we have gathered lets do 180-121 to give us 58

58 minus 9 is 49 and divide by ten the decimal gives us

4.9

10 times 4.9 is 50 plus 9 makes 58

Answer:

a+2

Step-by-step explanation:

The simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is 1/2 (2a+4). The expression will be solved as below,

E = 1/2 (2a+4)

E = (2a / 2 ) + ( 4 / 2 )

E = a + 2

Therefore, the simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.

Answer:

23/3 OR 7 and 2/3

Answer:

Step-by-step explanation:

Since no information is given how much an animal will consume per day so we will suppose that each animal will have at least two meals per day so in two weeks which is 14 days will have 28 meals in it so we will make an equality that

Let X be the amount they consume in each meal

for lion

[tex]28*X \leq 10[/tex]

which will give us 0.375 ponds each meal for the lion

similarly for the peacock

[tex]28*X\leq 5[/tex]

that gives us 0.1785 ponds of seed each meal

we can also make the meals once a day and in 14 days we can make 14 meals and in that case the meal will be

for lion it will be 0.750 pounds

for peacock it will be 0.375

Answer:

12 feet

Step-by-step explanation:

when you have c (the hypotenuse) and a (the opposite side) but you need to find b (the base) you have to flip around the theorm from a^2 + b^2 = c^2 to c^2 - a^2 = b^2.

then you plug in your numbers: 20^2 - 16^2 = b^2

then you solve the exponents: 400 - 256 = b^2

and subtract: 144 = b^2

lastly you square root both sides to get your answer: 12 = b

Answer:

Substituting a = x and b = 3 into the formula yields: x 3 + 27 = (x + 3) (x 2 − 3 x + 9).

Step-by-step explanation:

Answer: only x=3 is a solution and only x=1 is an extraneous root

For the given expression (x/x-1) - (3/x) = 1/x-1 both x=3 and x=1 are solutions. The correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is  (x/x-1) - (3/x) = 1/x-1. Check the solution of the expression,

(x/x-1) - (3/x) = 1/x-1

( 3 / 3 - 1 ) - ( 3 / 3 ) = 1 ( 3 - 1 )

( 3 / 2 - 1 ) = 1 / 2

1 / 2 = 1/2

For x = 1 the value is the same.

Therefore, both 3 and 1 are solutions to the given formula (x/x-1) - (3/x) = 1/x-1.

Answer:

The probability mass function of X is:

[tex]p_{X}(x)={n\choose x}(p)^{x}(1-p)^{n-x};\ x=0,1,2,...n[/tex]

Step-by-step explanation:

A Binomial experiment has the following properties:

• There are a fixed number of trials (n).

• Each trial are independent of the others.

• Each trial has only two outcomes: Success and Failure

• Each trial has the same probability of success (p).

If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.

Then the probability mass function of X is known as binomial probability distribution.

The probability mass function of X is:

[tex]p_{X}(x)={n\choose x}(p)^{x}(1-p)^{n-x};\ x=0,1,2,...n[/tex]

Answer:

350 hamburgers

Step-by-step explanation:

x = hamburgers

y = cheeseburgers

x + y = 750

y = x + 50

Using substitution:

x + (x + 50) = 750

2x + 50 = 750

2x = 700

x = 350

y = 350 + 50 = 400
