The value of y is directly proportional to the value of x. If y = 45 when x = 140, what is the value of y when x = 70?
Answers
Step-by-step explanation:
Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX
"K" is the constant of proportionality and must be determined from the initial information.
If Y = 45 when X=140 means 45 = 140K
K = 45/140 = 0.32
Now that we know the value of K, we can use it to calculate the value of Y when X=70
Y = (0.32)(70) = 22.4

statistical question Len could ask?
O A. How tall is a red kangaroo?
O B. Are there red kangaroos in Asia?
• C. Are red kangaroos an endangered species?
O D. What iS the tallest red kangaroo ever recorded?
Answers
Answer:
A statistical question Len could ask is "How tall is a red kangaroo?"
Step-by-step explanation:
A statistical question is something that we can ask and test hypotheses about using collected data. There will not be a specific answer, but rather multiple answers and we can average them in a sampling distribution.
Let's examine each question:
"How tall is a red kangaroo?"
There is not a specific height for each kangaroo, so we can take the averages of many different samples and find the "true mean" in the sampling distribution. This is a good example of a statistical question because data can be collected on red kangaroos and means can be calculated."Are there red kangaroos in Asia?"
"Are red kangaroos an endangered species?"
What is the tallest red kangaroo ever recorded?"
These are all examples of non-statistical questions. They are "yes" or "no" questions, and we cannot take multiple samples to determine the answer. Rather, there is a single answer that we do not need to test hypotheses or perform any statistical calculations.Calculate the area of the red triangle to find the area of the garden. Show your work.

How many times as many grams of rice does each

States> Round your answer to the nearest tenth.
Answers
Using proportions, it is found that each person consumes 3.57 times as many rice in Brazil and they do in the United States.
What is a proportion?A proportion is a fraction of a total amount.
In this problem, we have that:
The rate in Brazil is of [tex]5 \times 10^4[/tex].The rate in the United States is of [tex]14000 = 1.4 \times 10^4[/tex].Hence, the rate between the consumption in Brazil and in the United States is given by:
[tex]r = \frac{5 \times 10^4}{1.4 \times 10^4} = 3.57[/tex]
Each person consumes 3.57 times as many rice in Brazil and they do in the United States.

f(x)=−2x+16

please give me the intersection points
Answers
Answer:
(1, 14)Step-by-step explanation:
The intersection is when both functions have same coordinates
f(x) = g(x)Substitute to get
- 2x + 16 = 4x + 104x + 2x = 16 - 106x = 6x = 1The y- coordinate is
y = - 2(1) + 16 = -2 + 16 = 14So the intersection point is (1, 14)
Answer:
(1, 14)
Step-by-step explanation:
Given functions:
[tex]\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}[/tex]
Substitute the function notation for y to create a system of equations:
[tex]\begin{cases}y=-2x+16\\y=4x+10\end{cases}[/tex]
To find the points of intersection of the given functions, solve the system of equations.
Multiply the first equation (function f(x)) by 2:
[tex]\implies 2y=-4x+32[/tex]
Add this to the second equation (function g(x)) to eliminate x:
[tex]\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}[/tex]
Solve for y:
[tex]\implies 3y=42[/tex]
[tex]\implies y=14[/tex]
Substitute the found value of y into one of the equations and solve for x:
[tex]\implies 4x+10=14[/tex]
[tex]\implies 4x=4[/tex]
[tex]\implies x=1[/tex]
Therefore, the point of intersection of the given functions is (1, 14).

The equation of the line in point-slope form is y - 2 = -4(x + 5).

Use the point-slope equation: [tex]y-y_1=m(x-x_1)[/tex].
Substitute the point (-5, 2) and the slope m = -4 into the equation.
[tex]y-(2) = -4(x - (-5))[/tex][tex]y-2=-4(x+5)[/tex]If we stop here, this is the equation of the line in point-slope form.

Step-by-step explanation:
Area of Rectangle: Area = Length * Width
Given information:
Area = 22 in^2Length = 2x - 1Width = x - 4Put that into the Formula.
Area = Length * Width
22 in^2 = (2x - 1) * (x - 4)
Solve.
22 in^2 = (2x - 1) * (x - 4)
[tex]22 = (2x^2 - 9x + 4)\\2x^2 - 9x - 18 = 0[/tex]
Factor it.
(2x^2 - 9x - 18) = 0
(2x + 3)(x-6) = 0
[tex]x=-\frac{3}{2} ,6[/tex]
Plug that into the Length and Width to find the actually Length and Width.
Length:
[tex]2x - 1\\2*-\frac{3}{2}-1\\ -3-1\\-4\\[/tex]
Width:
[tex]x - 4\\-\frac{3}{2}-4\\ -\frac{11}{2}[/tex]
Area = Length * Width
Area = - 4* -11/2
Area = 22
Length:
[tex]2x - 1\\2*6-1\\ 12-1\\11\\[/tex]

Area = Length * Width
Area = 11 * 2

We use the distributive property to go from 7(r+4) to 7*r+7*4
Multiply the outer 7 by each term inside.
Then the -3 tags along without any changes to it

Since they are supplementary they form a straight angle, or 180 degrees so the angle AED is 112
Answer:
112
Step-by-step explanation:
∠AED and 68 are Linear pair angles.
That is their sum will be equal to 180,
∠AED + 68 = 180
∠AED = 180 - 68
∠AED = 112
