We need to find the average termperature change per hour during January 2008.

We have the information that Minnesota fell from 41 degrees to -13 degrees over 24 hours.

Then, 41 degrees to -13 degrees, there is a difference of 41+13 = 54 degrees over 24 hours.

If the difference is over 24 hours, then:

54 degrees / 24 hours =2.25 F is the rate of change.

However, the termperature is decreasing, so the rate of change must be negative.

Hence, the rate of change = -2.25 F.

The correct answer is the third option.

To determine the post image coordinates after a dilation centered about the origin, we will simply multiply each of the coordinates by the given scale factor of 1/3.

Step-by-step explanation:

rate(time) of one pipe + rate(time) of the other pipe = 1 job

The rate would be the the number of jobs over the time

The rate of the first pipe is 1/5 and the rate of the second pipe is 1/8.

Together:

1/5t + 1/8t = I job

t(1/5 + 1/8) = 1

t(8/40 + 5/40) = 1

t(13/40) = 1  multiply each side by 40/13

t(40/13)(13/40) = 1(40/13)

t = 40/13

t = 3 1/13

Step-by-step explanation:

This question is asking us to find the points of intersection, which means its asking to find the x-intercept abd y-intercept.

To find the x-intercept, we know that y = 0.

Therefore we can substitute y = 0 into the line equation:

[tex]0 = - \frac{1}{4} x + 2 \\ - \frac{1}{4} x = - 2 \\ x = - 2 \div - \frac{1}{4} \\ = 2 \times 4 \\ = 8[/tex]

Therefore the point of the x-intercept is (8,0).

Likewise to find the y-intercept, we know x = 0.

Therefore we can substitute x = 0 into the line equation:

[tex]y = - \frac{1}{4} (0) + 2 \\ = 0 + 2 \\ = 2[/tex]

Therefore the point of the y-intercept is (0,2).

Answer:

x-intercept:  (8, 0)

y-intercept:  (0, 2)

Step-by-step explanation:

Given equation:

[tex]y=-\dfrac{1}{4}x+2[/tex]

The graph intersects the y-axis when x = 0.  

To find the graph's y-intercept, substitute x = 0 into the equation and solve for y:

[tex]\begin{aligned}x=0 \implies y&=-\dfrac{1}{4}(0)+2\\y&=0+2\\y&=2\end{aligned}[/tex]

Therefore, the coordinates of the point of intersection with the y-axis are:

The graph intersects the x-axis when y = 0.  

To find the graph's x-intercept, substitute y = 0 into the equation and solve for x:

[tex]\begin{aligned}y=0\implies \-\dfrac{1}{4}x+2&=0\\-\dfrac{1}{4}x&=-2\\x&=8\end{aligned}[/tex]

Therefore, the coordinates of the point of intersection with the x-axis are:

Since we have that y = 10, then:

Then

In the first part, we need to sum 15 to both sides of the equation.

In the second part, we divide both sides by 5.

Then, x = 19.

The value of the function f(7/3)-h(-2) is 30

Functions are simply defined as theorems, laws, equation or rules that holds true for the relationship between two variables in a given expression.

The variables are known as;

Given the functions as;

To determine f(73), substitute the value as x in the function, we have;

f(7/3) = 3(7/3) - 1

expand the bracket

f(7/3) = 7 -1

f(7/3) = 6

For h(-2), substitute the value as x in the function, we have;

h(-2) = -2(-2)² + 3(-2) - 9

expand the bracket

h(-2) = -8 -6 - 9

Subtract the values

h(-2) = -23

Now, f(7/3)-h(-2) = 7 --23

f(7/3)-h(-2) = 30

Given:

Ethan is 23 years older than Evan

So, let Ethan is (x) years old

And Evan is (y) years old

So, the difference between them is 23 years old

so, x - y = 23

And the sum of Ethan and Evan's age is 43

so, x + y = 43

So, we have the following system of equations:

add the equations to eliminate (y):

Now, substitute with (x) into the second equation to find (y):

So, the answer will be:

From the figure given in the question, we are asked to find the area and perimeter.

(a) Area:

Since the figure is a trapezoid, the formula for the area of a trapezoid is:

Area = (a + b)h

2

Where:

a = 2

b = 5

h = 4

Area = (2 + 5)4

2

Area = 7/2 * 4

Area = 3.5 * 4

Area = 14 cm²

(b) Perimeter:

To get the perimeter, we will have to add all the side length.

But we will have to find the missin side length first.

Using pythagoras:

a² + b² = c²

Where:

a = 4

b = 3

c² = 4² + 3²

c² = 16 + 9

c² = 25

Taking square of both sides:

c = √25

c = 5

Since we have gotten the missing side length as 5cm, we can now add all the given side length to get the perimeter.

Perimeter = 4 + 2 + 5 + 5

Perimeter = 16 cm

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign.

Given:

2m -3 = 3/10 (5m - 12)

Now, cross multiplying

10( 2m -3)= 3( 5m -12)

20m -30 = 15m - 36

20m- 15m= -36 + 30

5m = -6

Divide both side by 5

m= -6/5

Verification:

LHS = 2m-3

=2(-6/5)-3

=-12/5-3

=-27/5

and, RHS

= 3/10( 5m -12)

=3/10(5 x (-6/5) -12)

The values of x and y are 26° and 54° respectively.

Consider the triangle with x is triangle 1

Triangle with y is triangle 2

In triangle 1

Since it is a right angled triangle one angle is already known

Another angle is 64°

We know the sum of interior angles of a triangle is equal to 180

Hence 90 + 64 +x = 180°

154 + x = 180°

x= 180 - 154

x = 26°

From triangle 2 it is evident that x and y are complementary angles which means they sum up to 90°

Hence  x + y = 90°

26 + y = 90

y = 90 - 26

y = 54°

Hence the value of x and y are 26° and 54° respectively

Answer: Slope of 1.

Step-by-step explanation:

    First, we will put the equation into slope-intercept form.

x - y = 4

x = y + 4

y = x - 4

    Our slope, when the line is written as y = mx + b, is the m value. Our m value here is one, so the slope of a line parallel to the line whose equation is x - y = 4 is 1.

A fraction, which derives from Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal pieces. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of particular size there are when stated in ordinary English. A common, vulgar, or simple fraction is one that has a non-zero denominator that is displayed below (or after) line on which the numerator is shown. Compound fractions, complicated fractions, and mixed numeral fractions are the examples of uncommon fractions that use numerators and denominators.

The numerator and the denominator of positive common fractions are both natural integers. The denominator shows how many of numerator's equal parts make up a unit or whole, and the numerator reflects the number of equal parts. Since there can never be zero components in a whole, denominator cannot be zero. For instance, numerator 3 in the fraction 3/4 denotes that the fraction is made up of 3 equal parts, while denominator 4 denotes that the fraction is made up of 4 parts altogether.

Let, [tex]\frac{3}{8} x[/tex] animals are dogs,

Hello there. To solve this question, we'll have to remember some properties about scatter plots and slope of a line.

Given the scatter plot of the data information, we have to determine the slope of the line.

For this, we could determine it numerically using the least squares method, if we knew the data (the coordinates of the points we're plotting the best fit).

In this case, we simply need to find, by inspection, two points contained in the line and use the slope formula.

Given two points (x0, y0) and (x1, y1) that a line L passes through, then the slope m of this line is given by:

By inspection, we can easily spot the points (16, 12) and (28, 20).
