Answer:
t = [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
10t - 19 = 7t - 14
Subtract 7t from both sides;
3t - 19 = -14
Add 19 to both sides;
3t = 5
Divide both sides by 3;
t = [tex]\frac{5}{3}[/tex]

At a food festival, 3/8 of the dishes were from china. Another 12.5% of the dishes were from japan. What percent of the dishes were from the other countries?
Answer: 50%
Step-by-step explanation:
Let x = Total dishes.
Dishes from China = [tex]\dfrac38x[/tex]
Dishes from Japan = [tex]12.5\% \text{ of }x= 0.125x[/tex]
Total dishes from China and Japan = [tex]\dfrac38 x+0.125x=0.375x+0.125x=0.5x[/tex]
Dishes from other countries [tex]= x- 0.5x= 0.5x[/tex]
Percent of dishes from other countries= [tex]\dfrac{0.5x}{x}\times100\%= 50\%[/tex]
Hence, dishes from other countries = 50%
The volume of a box is 120 cubic feet, the width and length are equal to x, the height is y. Find the dimensions that use the least amount of material. V=x^2 * y
Answer:
The answer is below
Step-by-step explanation:
The volume of box = width * length * height
120 = x * x * y
120 = x²y
y=120/x²
The surface area (SA) = sum of the area of all faces side
SA = x² + x² + xy + xy + xy + xy
SA = 2x² + 4xy
substitute y =120/x²
SA = 2x² + 4x(120/x²)
SA = 2x² + 480/x
Taking the derivative:
SA' = 4x - 480/x²
making SA' = 0:
0 = 4x - 480/x²
480/x² = 4x
4x³ = 480
x³ = 120
x = 4.93 feet
y = 120 / x² = 120 / 4.93² = 4.93
Hence the width, length and height is 4.93 feet.

Domain is the set of x-values that can be inputted into function f(x).Step-by-step explanation:
Step 1: Define function
f(p) = 4p + 1000
Step 2: Analyze
We note down that we are not given a restriction or an interval with the function. We also note down that we can plug in any number x and it would give us an output.
Therefore, our domain is All Real Numbers or (-∞, ∞)

Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How much money did the West Raise?
9514 1404 393
Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.

Randy collected two different data sets and labeled them data set Q and data set R. Data set Q has a correlation coefficient of −0.87,
and data set R has a correlation coefficient of −0.96.
Part A: Which data set has a stronger linear relationship?
Part B: How do you know this?
Select two answers, one for Part A and one for Part B
Answer:
Part A: Data set R
Part B: The correlation coefficient ranges from -1 to 1, where -1 represents a strong negative correlation and 1 represents a strong positive correlation. Data set R has a correlation coefficient of -.96, which has an absolute value that is closer to 1 than Data set Q's -.87, which means that it has a stronger linear relationship.
The data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
We have:
Correlation coefficient for data set Q = -0.87
Correlation coefficient for data set R = -0.96
The data set R has a stronger linear relationship because the value of correlation coefficient is -0.96 which is close to -1.
As we know the correlation coefficient varies between -1 to +1 when the value of correlation coefficient is close to -1 or +1 the relationship is strong.
Thus, the data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.

Which equation represents the line that is perpendicular to y= 1/6 and passes through (-8,-2)?
We want to find a line that is perpendicular to y = 1/6 and that passes through (-8, -2), that line will be x = -8.
Working with perpendicular linesSo we want to get a line, we know it must be perpendicular to y = 1/6.
Notice that y = 1/6 is a horizontal line, then our line must be vertical, this means that our line is something like x = constant.
Now if we want our line to pass through the point (-8, -2), the constant must be equal to the x-value of the point, this is:
x = constant = -8
x = -8
This is the equation of the line perpendicular to y = 1/6 and that passes through (-8, -2)
