Answer:
113
$1.13
Step-by-step explanation:
22x + 3 when x = 5 is written 22(5) + 3
You multiply first, 22(5) = 110 + 3 = 113
a nickel is worth .05 so you mulitply .05 x 22 which gets you 1.1 and 3 pennies is .03 and when you add the two together you get $1.13
Answer: The value of 22x+3 is 113. The amount of money that equals 22 nickels and 3 pennies. That answer is also 1113.
Step-by-step explanation:
For the first problem u want to basically do 22 times 5 and that gives you 110. Then after doing that u want to do 110+3 which equals 113.
For the second one since nickels equal 5 cents u want to do 22•5 which gives you 110 and then you do 110+3 and that gives you 113.

What is the domain of the function graphed ? F(x)=√x+4
A. x≤-4
B. x≥0
C. x≥-4
D. x≥4
The domain of the function F(x) = √(x+4) is all real numbers greater than or equal to -4, which corresponds to option C. x≥-4.
Explanation:The student has asked about the domain of the function F(x) = √(x+4). To determine the domain of this function, we need to consider the values of x for which the expression under the square root, x+4, is non-negative, since the square root of a negative number is not defined in the set of real numbers.
The expression x+4 is non-negative when x ≥ -4. Therefore, any number greater than or equal to -4 is part of the domain of the function.
This means the correct answer to the question is C. x≥-4.
What is standard form of 7x1+3x(1/10)+4x(1/100)
Answeuse a caculator then write it our
Step-by-step explanation:
The standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is 0.7304 x [tex]10^{1}[/tex].
Given,
7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 )
We need to write this large number in standard form.
What is a standard form?A standard form is a way of expressing a large number as a decimal number between 0 and 1 (including 1) and multiplied by a power of 10.
We have,
7 x 1 + 3 x ( 1 / 10 ) + 4 x ( 1 / 1000 )
7 + 0.3 + 0.004
7.304
Since we need a decimal point between 0 and 1.
We will multiply 7.304 by 10 / 10.
so we have,
7.304 x 10 / 10
(7.304 / 10 ) x 10
0.7304 x 10
Remember that a number to the power 1 is the number itself.
[tex]10^{1} = 10[/tex]
We see that in 0.7304 x [tex]10^{1}[/tex],
0.7304 is a decimal point between o and 1 and we have a power of 10.
It satisfies the standard form of a number.
Thus the standard form of 7 x 1 + 3 x ( 1/10 ) + 4 x ( 1 / 1000 ) is
0.7304 x [tex]10^{1}[/tex].

A pond is being drained through an outlet pipe, then will be filled through an inlet pipe. If the inlet pipe can fill the pond in 9 hours and the outlet pipe can empty the pond in 15 hours, how long would it take to fill the pond if the outlet pipe was left open?
Answer:
22.5 hours
Step-by-step explanation:
I am using "1 pond" to mean the volume of water that fits in the pond.
The inlet pipe fills the pond in 9 hours.
The filling rate is (1 pond)/(9 hours) = 1/9 pond/hour
The outlet pipe empties the pond in 15 hours.
The emptying rate is (1 pond)/(15 hours) = 1/15 pond per hour
The difference in rates is the net rate at which the pond is filling up.
1/9 pond/hour - 1/15 pond/hour =
= 5/45 pond/hour - 3/45 pond /hour
= 2/45 pond/hour
The pond is filling at a rate of 2/45 pond/hour.
To find the time it takes to fill the pond, we divide 1 pond by the rate.
(1 pond)/(2/45 pond/hour) = 45/2 hour = 22.5 hours

Answer:
SORRY DONT KNOW
Step-by-step explanation:
the measure of angle ∠21 must be 55 degrees for line b to be parallel to line a.
In order for line b to be parallel to line a, the measure of angle ∠21 must be 125 degrees. Corresponding angles are angles that are in the same position relative to two intersecting lines. Since lines a and b are parallel, we know that corresponding angles ∠1 and ∠21 are congruent. Therefore, we can set up the following equation to find the measure of ∠21:
∠1 + ∠21 = 180° (because they are supplementary angles)
Substituting 125° for the measure of ∠1, we get:
125° + ∠21 = 180°
Solving for ∠21, we get:
∠21 = 180° - 125°
∠21 = 55°

Hey there!
3(x - 4) = x + 4
3(x) + 3(-4) = x + 4

What are the solutions of the following equation?
4|x -9| +9 = -3|x -9| +9 4∣x−9∣+9=−3∣x−9∣+9
Answer:
x = 9
Step-by-step explanation:
4∣x−9∣+9 = −3∣x−9∣+9
cancel equal terms on both sides of the equation
4∣x−9∣+9 = −3∣x−9∣+9the statement is true but only if both sides equal 0
4∣x − 9∣= −3∣x − 9∣4 x | x - 9| = 0−3∣x − 9∣= 0solve the equation for x
4x |x -9| = 0divide both sides of the equation by 4
|x-9| = 0when the absolute value of x - 9 equals 0, then x - 9 = 0
x - 9 = 0move the constant to the right side and change it´s sign
x - 9 = 0x = 9so the answer would be x = 9

four times the difference of b and six is equal to b squared
Answer:
4(b-6)=b^2
Step-by-step explanation:
The difference would mean that it is subtraction and you multiply that difference by 4 and set it equal to b squared
According to the statement, the given equation is 4(b - 6) = b², and the value of b is 2 + 4.472i and 2 - 4.472i.
To solve the equation given: 4(b - 6) = b², we need to first expand and simplify.
4b - 24 = b²
b² - 4b + 24 = 0
b = 2 + 4.472i and 2 - 4.472i.

What is equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left-hand side = right-hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign. It will be regarded as a phrase.Mathematicians refer to equations with a degree of 1 as linear equations. The largest exponent of terms in these equations is 1, which equals. These can also be broken down into linear equations with one variable, two variables, three variables, etc. A linear equation with the variables X and Y has the conventional form aX + bY - c = 0, where a and b are the corresponding coefficients of X and Y and c is the constant.Given, the center is open for 11 hours each day and each party takes three hours. There are 4 rooms.
Therefore, 11 ÷ 3 = 3 (approx)
Each room can host 3 parties each day.

thank you for your time!
Step-by-step explanation:
In Mathematics, the order of operations (BOMDAS or BIDMAS) dictates that multiplication operations should be performed before addition. Hence, in the mathematical expression '80 + 80 equals 80 + 80 * 80 equals', the multiplication operation (80*80) is performed first, resulting in '80 + 6400 = 6480'. Therefore, 80 + 80 equals 6480.
Explanation:In Mathematics, the operation order matters, this order is known by the acronym BOMDAS or BIDMAS, which stands for Brackets, Orders, Multiplication and Division, and Addition and Subtraction. it is used to clarify which procedures should be performed first in a given mathematical expression.
In your question, '80 + 80 equals 80 + 80 * 80 equals', we have both addition and multiplication operations. According to BIDMAS rules, we perform multiplication first before addition. Hence, the given expression is equivalent to 80 + 80 equals 80 + (80 * 80), where (80*80) should be calculated first.
Putting this into practice, we get: 80 + (80 * 80) = 80 + 6400 = 6480. Therefore, 80 + 80 equals 6480, based on the principles of BIDMAS or BOMDAS.
