4 ft by 8 ft

Step-by-step explanation:

Answer:

D. 4ft by 10ft

Step-by-step explanation:

Since each square represents 4 feet and the door is 2 blocks plus a bit up it can't be 8 ft since 8ft would only be 2 blocks exactly, this also rules out B since 12 ft would need to be 3 blocks high. this leaves A and D. The third square is only half of a normal square which means its half of 4, 2. You add this to 8 to get 10.

An employee at a homemade wooden toy store earned $860 over the past week. The employee needs to pay 14% for Federal Income Tax and 3% for State Income Tax, both on the initial amount he earned. How much will the employee earn after paying both taxes?
$

Answers

Answer:
$713.8

Explanation:
14%of 860 = 120.4

3% of 860 = 25.8

so, subtract the sum of the above 2 values from 860.

860 - (120.4+25.8) = 860-146.2 = 713.8

Hope this helps

Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

What is percentage?

Percentage is a "number or ratio that can be expressed as a fraction of 100".

According to the question,

An employee earned $860 over the past years. The employee needs to pay 14% for income tax and 3% for state income tax

Find an employee needs to pay in Federal income tax:

[tex]\frac{14}{100}[/tex] × 860 = 120.4

Find an employee need to pay in State income tax:

[tex]\frac{3}{100}[/tex] × 860 = 25.8

In order to find an  employee earn after paying both taxes only if we sum the amount of taxes paid by an employee and subtract from earned amount by past years.

860 - (120.4  + 25.8) =713.8

Hence, Using Percentage, the employee earn after paying Federal income tax and state income tax is $713.8.

Which parent function is represented by the graph?
5+
A. Linear parent function
A
B. Quadratic parent function
C. Absolute value parent function
D. An exponential parent function

Answers

Answer:

quadratic parent function

Step-by-step explanation:

squares cannot be negative no matter what you cannot square a number into a negative number which is why there are no negative y values because y is a function of X

The parent function is represented by the graph is an exponential parent function, the correct option is D.

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

Linear function is a function whose graph is a straight line

We are given that;

The graph of function

Now,

To identify which parent function is represented by the graph, we can look at the shape and features of the graph. The graph shows a curve that starts from the lower left quadrant and rises rapidly as x increases. The graph passes through the point (0, 1) and has a horizontal asymptote at y = 0. These are the characteristics of an exponential parent function with a base greater than 1.

Therefore, the function will be an exponential parent function.

Solve the simultaneous equations
x + 5y = 16
x + 3y = 10

Answers

Answer: x=1 and y=3

Step-by-step explanation: hope this help

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The linear equations are given below.

x + 5y = 16        ...1

x + 3y = 10        ...2

Subtract equation 2 from equation 1, then we have

x + 5y - x - 3y = 16 - 10

2y = 6

y = 3

Then the value of the variable 'x' will be given as,

x + 5(3) = 16

x + 15 = 16

x = 1

The solution of the linear equations x + 5y = 16 and x + 3y = 10 will be (1, 3).

More about the solution of the equation link is given below.
