Answer:
Please check explanations
Step-by-step explanation:
When we talk about the slope, we are simply referring to the change in y-value with respect to a change in x-value
From the regression line equation, we can see that the value of the slope is negative
What this means is that as the x value is increasing, the y value is decreasing
This makes sense in the context of the problem because it is expected that the amount of fuel in liters is expected to decrease with an increasing amount of time
please help me!!!!! im confused
Answer:
The interest is: $2550.00
Step-by-step explanation:
I = P x r x t
P is the principal amount, $12000.00.
r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:
The interest is: $2550.00

Answer:
[tex]\frac53[/tex]
Step-by-step explanation:
Hello!
Slope is calculated by the formula [tex]\frac{Rise}{Run}[/tex].
Rise is the change in y between two pointsRun is the change in x between two pointsThe two points I'm going to pick are (0,-1) and (3,4).
Now let's find the changes in x and y.
Change in y (-1 and 4) is 5Change in x (0 and 3) is 3Plugging it into the formula, you get a slope of [tex]\frac53[/tex].

Two triangles have the same base lengths. One Triangle has the height that is 4 times the height of the other triangle. Are the heights and the areas of the two triangles proportional?
YES
Area of Triangle 1Base=b
Height= h
Area 1=A1=1/2*b*h
Area of Triangle 2Base=b
Height= 4h
Area of triangle 2=A2=1/2*b*4h
Comparing A1 and A2A2/A1= (1/2*b*4h)/(1/2*b*h)
= (1/2*b*4h)/(1/2*b*h)
=4/1
Ratio of heights =h2/h1= 4/1
Ratio of areas =A2/A1= 4/1
They are proportional.

What criteria must a polygon meet to be considered inscribed in a circle?
Help ASAP!!
he criteria for polygon inscribed in a circle is every vertices are points on the circle and all sides are included within the circle.
What is the polygon?Polygon is "any two closed curve consisting of a set line segments connected such that no two segments connected".
According to the question,
A polygon is inscribed in a circle if its all vertices are points on the circle and all sides(Edges) are included within the circle. All regular polygon can be inscribed in a circle. The center of an inscribed polygon is also the center of the circumscribed circle.
Hence, the criteria for polygon inscribed in a circle is every vertices are points on the circle and all sides are included within the circle.

Ap ex: What is the solution to this system of equation?
y = x - 4 y = -0.5x + 8
a. (4,2)
b. (8,4)
c. (4,8)
d. (2,4)
Answer:
x = 8, y = 4
Step-by-step explanation:
y = x - 4
y = -0.5x + 8
y = y
x - 4 = -0.5x + 8
x + 0.5x = 8 + 4
1.5x = 12
x = 12/1.5
x = 8
To get "y" substitute the 8 for the "x" value in any of the two equations (they will both give the same answer.)
y = (8) - 4
y = 4
OR
y = -0.5(8) + 8
y = -4 + 8
y = 4
Suppose a lab need to need to make 400 liters of 39% acid solution, but the only solutions available to the lab are 20% acid and 50% acid. What system of equation can be used to find the number of liters of each solution the should be mixed to make the 39% solution? Let c represent the number of liters of 20% acid solution and let d represent the number of liters of 50% acid solution.
Answer:
c + d = 400
0.2c + 0.5d = 156
Step-by-step explanation:
Let
c = number of liters of 20% acid solution
d = number of liters of 50% acid solution.
c + d = 400 (1)
0.2c + 0.5d = 400(0.39)
0.2c + 0.5d = 156 (2)
From (1)
c = 400 - d
Substitute c = 400 - d into (2)
0.2c + 0.5d = 156 (2)
0.2(400 - d) + 0.5d = 156
80 - 0.2d + 0.5d = 156
- 0.2d + 0.5d = 156 - 80
0.3d = 76
d = 76/0.3
d = 253.33 liters
Substitute d = 253.33 into (1)
c + d = 400
c + 253.33 = 400
c = 400 - 253.33
c = 146.67 liters

Which one of these transformations would produce an image that is not congruent to its pre-image? (4 points)
A translation of (x − 1, y − 3)
A rotation of 90 degrees about the origin
A rotation followed by a translation
A dilation followed by a reflection
Answer:
A dialation followed by a reflection
Step-by-step explanation:
When you dialate a shape it changes the size which makes the shape similar but not congrouent.
The option “a dilation followed by a reflection” will produce an image that is not congruent to its pre-image option, fourth is correct.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
As we know, the translation will shift the object.
If rotate the image with 90 degree about origin will change the orientation of the image but shape will remains same.
A dilation followed by reflection will change the image because the transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller.
Thus, the option "a dilation followed by a reflection" will produce an image that is not congruent to its pre-image option fourth is correct.

Three times a day, Dylan mixes 2 ounces of protein powder into a shake. How many days can he make all three shakes from his 5-pound container of protein powder? Remember, there are 16 ounces in a pound. Enter your answer in the box.
Answer:
13 days
Step-by-step explanation:
To calculate this we first need to find the total number of ounces in the container. We do this by multiplying the total number of pounds in the container by 16oz
5 * 16oz = 80oz
Since Dylan is making three 2oz shakes per day that would mean he is using a total of 6oz (2oz*3) per day. Therefore, in order to find out how many days the container will last we simply divide the total amount of protein powder in the container by the amount he uses every day.
80oz / 6oz = 13.33 days
The container will last 13.33 days but since we cannot count a percentage of a day, then we need to round down to the day in which he will no longer be able to make the three shakes which are 13 days.
Answer:
13

c) The area of a rectangle is 80 cm² and it is 8 m broad.In process
(i) Find its length (ii) Find its perimeter
11
Answer:
i) the length is 10cm
ii) the perimeter is 36 cm
Step-by-step explanation:
i) We know that Area of a rectangle can be found by using the following formula...
A = l x w
(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).
From this we know that
l = A/w
[tex]l = 80cm^{2} / 8cm = 10cm[/tex]
ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...
P = 2(l + w)
[tex]P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm[/tex]
