in a carton, 3 out of 10 glasses are cracked. what percent of glasses are not cracked?
Answers
Answer:
70%
Step-by-step explanation:
[tex]\frac{3}{10}[/tex] = [tex]\frac{30}{100}[/tex] = 30%
100 - 30 = 70
Answer:
70% are not cracked
Step-by-step explanation:
So 10 = 100%
So each bottle equals 10%
If 3 glasses are cracked it would be 30% cracked
So subtract 30 from 100 and you get 70%

Craig solves the following system of equations using the elimination method.
2x+4y=164x+8y=−16
He chooses to eliminate the variable y.
Which statement correct describes his process and solution?
A. Craig multiplies 2x + 4y = 16 by 2 and then adds the equations. He finds the result is an identity, so there are infinitely many solutions.
B. Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution.
C. Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is an identity, so there are infinitely many solutions.
D. Craig multiplies 2x + 4y = 16 by 2 and then adds the equations. He finds the result is a contradiction, so there is no solution.
Answers
Answer:
the answer is b. I know this because ima teacher.
Step-by-step explanation:
Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. The correct option is B.
What is system of equations?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between two or more variables.
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
Given equations are 2x+4y=16 and 4x+8y=−16. The equations will be solved as below,
2x+4y=16
4x+8y=−16
Multiply the first equation by 2 and solve,
4x+8y=16
4x+8y=−16
Therefore, Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. The correct option is B.

f(x) = x - 3 gives
1-3, 2-3, 3-3, 4-3 ..

The sequence represents the function f(x)=x−3, with a domain of natural numbers will be {-2,-1,0,1.............}. The correct option is C.
What is a function?
A function is defined as the expression that set up the relationship between the dependent variable and independent variable. The collection of possible inputs into a function, or the set of input values for which the function is defined, is known as the domain of the function.
The natural numbers are 1, 2, 3, and 4......
f(x) = x - 3 gives
f(1) = 1 - 3 = -2
f(2) = 2-3 = -1
f(3) = 3-3 = 0
f(4) = 4-3 = 1
The sequence is {-2, -1, 0, 1 ..}. Therefore, the sequence represents the function f(x)=x−3, with a domain of natural numbers will be {-2,-1,0,1.............}. The correct option is C.

3.9%
6%
Answers
Answer: 3.9%
Step-by-step explanation:
First, subtract the two values:
16 - 15.4 = 0.6
Now divide this to the actual area:
0.6 / 15.4 = 0.038961039
Multiply by 100:
0.038961039 * 100 = 3.8961039
So the percent error is approximately 3.9%

How many solutions does 8p + 1 = 4p +2 have?
Answers
Step-by-step explanation:
8p + 1 = 4p + 2
8p - 4p = 2 - 1
4p=1
4p/4p=1/4p
p=0.25
The equation 8p + 1 = 4p + 2 have one solution which is p = 0.25.
What is an Equation?Equations are mathematical statements where we write two expressions which is equal to each other. There will be a left hand side and a right hand side on either sides of an equation.
The main classes of equations in algebra are linear equations and polynomial equations. On these include quadratic equations, cubic equations, differential equations and so on.
We have the expressions 8p + 1 and 4p + 1 equal to each other.
8p + 1 = 4p + 2
Subtracting the term 4p on both sides, we get,
8p + 1 - 4p = 4p + 2 - 4p
4p + 1 = 2
Subtracting both sides with 1,we get,
4p + 1 - 1 = 2 - 1
4p = 1
Dividing both sides by 4, we get,
p = 1/4
p = 0.25
Hence there is one solution to the equation 8p + 1 = 4p + 2 which is p = 0.25.

Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in:
Answers
Answer:
the distance covered is 26.87 miles
Step-by-step explanation:
The computation of the distance covered is shown below:
As we know that
Speed = Distance ÷ Time
where
Speed is 8 2 ÷ 3 = 26 ÷ 3
And, the time required is 3 hours and 6 minutes i.e. 3 hours and 6 ÷ 60 = 3.1 hours
Now the distance covered is
= 26 ÷ 3 × 3.1
= 26.87 miles
hence, the distance covered is 26.87 miles

Equation 1;
3x + y = 9
y=9-3x
Equation 2:
5x-3y=1
5x+3(9-3x)=1
5x+27-9x=1
-4x=-26
x =6.5
Hence, solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions.
Hence, option B is correct.

What is a function?A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.
Given,
function f(x) = x³ - 3x² - 4x
The properties of the function f(x) = x3 - 3x2 - 4x are as follows:
1) Factors: x (x+1) (x-4)
2) Zeros/roots: x = 0, x = -1, and x=4.
3) Leading coefficient is positive.
4) The graph rises to -1 on the x-axis before descending to cross through 0. It turns up once more through 4, then finishes by turning toward positive infinity.
5) Its graph resembles an upside-down S.
