Answer:
biconditional
Step-by-step explanation:
Given the conditional statement : p -> q
Its reverse is: q -> p
written in the "if and only if" is: p <-> q
gives us a biconditional statement.
A biconditional statement is defined to be true whenever both parts have the same truth value.
You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
Part A: Which equation can you use to solve for x , your normal hourly rate?
Part B: What is your normal hourly rate?
Equation that represents the given situation is 40x + 6 *1.5x = 612.50.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given, You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
First, define the variables. Let’s let x = his regular pay.
For first 40 hours pay = 40x
Over time pay = 1.5x
Since he worked 46 hours
Thus his over time pay = (46 -40) *1..5x
Thus his over time pay = 6 * 1.5x
Since, You worked 46 hours this week and earned $612.50.
linear equation that represents the given situation
40x + 6 *1.5x = 612.50
Normally hourly rate:
40x + 9x = 612.50
49x = 612.50
x =12.5
Therefore, Equation that represents the given situation is 40x + 6 *1.5x = 612.50.

Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
For the first equation,
h-3=9, we need to put all the knowns (numbers) on one side and all the variables on the other side. because equations are like a scale, if we do the same thing to both sides of the equation, the equation will still be true. for this equation, if we add 3 to both sides, we will get:
h-3+3=9+3
this can be simplified to:
h=12
this is your answer.
For the second equation,
we can apply the same principle for the first equation to the second equation.
1/2 x h = 10
can also be written as:
1/2 of h = 10
we can multiply both sides by 2 to get:
1h=20
or
h=20

The constant of Proportionality is 8.
What is constant of Proportionality?If the ratio of one variable to the other is constant, then there is a proportional relationship between the two variables. If x and y are in a proportional relationship, then the ratio of y to x is the constant of proportionality. We can also express it as x is to y at times.
Given:
Total Baseball Caps= 30
Total amount of Cap= $240
let the number of caps sold be c.
Then, the equation is
30 c= 240
and, c= 240/30
c= 8
Hence, the constant of Proportionality is 8.

Answer:
y=72
x=53
there are 72 packages
Step-by-step explanation:
3.5x+2.25y=347.5
x+y=125
Thereby y=125-x
so
3.5x+2.25(125-x)=347.5
3.5x-2.25x+281.25=347.5
1.25x=66.25
x=53
53+y=125
y=72
Answer:
60 rolls

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
\(8 \times 2 = 3 \times x.\)
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

The following scatterplot shows the number of hits and home runs from 20 baseball players who had at least 10 hits during the season. Using the scatter plot predict how many home runs a person who hit 125 times would have.
A) About 12
B) About 11
C) About 20
D) About 18
Answer:
\(\huge\boxed{\text{(D) About 18}}\)
Step-by-step explanation:
Using this scatterplot, a line has been graphed using linear regression. We can use this line as our reference point and ignore the rest of the points on the graph.
We can examine this graph and find approximately what value of y is given when we provide an x value.
Since the number of hits is the x value, we can look at the graph to find how high the graph goes at that x value.
125 is right between 100 and 150, so we can start there and move up.
When we move up, we get a line that's in between 10 and 20. We can also see it's in the top half of that box. That means that the value of y for this will be more than 15.
Since it's not lying directly on 20, the only option left is 18.
Hope this helped!

Maxwell invested a total of $100,000. He invested his money in three different accounts. He invested $35,000 at 10% annual interest rate, $42,000 at 8% annual rate, and the remainder at 14% interest rate. How much interest did Maxwell receive in one year?
Step-by-step explanation:
Sure! Here's the step-by-step calculation:
1. Calculate the interest earned on the first investment:
$35,000 * 10% = $3,500
2. Calculate the interest earned on the second investment:
$42,000 * 8% = $3,360
3. Calculate the amount invested in the third account:
Total investment - (First investment + Second investment)
$100,000 - ($35,000 + $42,000) = $23,000
4. Calculate the interest earned on the third investment:
$23,000 * 14% = $3,220
5. Add up the interest earned from all three investments:
$3,500 + $3,360 + $3,220 = $10,080
Therefore, Maxwell received $10,080 in interest in one year.

Which equations have a greater unit rate than the rate represented in the table? x y 3 2 6 4 9 6
Answer:
Any equation with a slope greater than ²/₃
Step-by-step explanation:
Given table:
\(\begin{array}{| c | c |}\cline{1-2} x & y \\\cline{1-2} 3 & 2 \\\cline{1-2} 6 & 4 \\\cline{1-2} 9 & 6 \\\cline{1-2} \end{array}\)
The unit rate is a ratio that compares the first quantity to one unit of the second quantity. The unit rate is also the slope of a linear equation.
Linear equation
\(y = mx + b\)
where:
m is the slopeb is the y-interceptTo find the slope, take two ordered pairs from the table:
\(\sf let \: (x_1,y_1)=(3,2)\)
\(\sf let \: (x_2,y_2)=(6,4)\)
Substitute them into the slope equation:
\(\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-2}{6-3}=\dfrac{2}{3}\)
Therefore, the unit rate is ²/₃.
Any equation with a slope greater than ²/₃ is an equation with a greater unit rate than that represented in the given table.
Slope of table
(3,2)(6,4)Slope
m=4-2/6-3m=2/3Any equation having slope greater than 2/3 has higher unit rate than that of table
