Answer:
[tex]\frac{-1}{7}[/tex] or 0.14
Step-by-step explanation:
To find slope you can use the formula
mx=[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
or
[tex]\frac{rise}{run}[/tex]
Rise over run:
Rise over run is the easiest of the two so we'll be using that one first for this question, but both should give you the same answer
To find rise over run, select the points and see how many points up or down you must got to make it the same level as the other point
In this case, the point (-3,1) would have a run of -1 because you have to move down one
To find run, now that you have rise start from that point and count how far you have to go to get to the next point. You should be going in a straight line.
The run would be 7.
Now you make it a fraction/division problem
[tex]\frac{rise}{run} =\frac{-1}{7}[/tex]
-0.14285714285714285714285714285714 <- decimal value
-0.14
Depending on what it means by reduce, your answer will either be -1/7 or the decimal. Use the reduced decimal value if it's asking for a decimal
I've included a picture in case my explanation was not satisfactory or you need a visual.
Slope form:
Identify the two points
First one will be (-3,1)
Second one would be (4,0)
Now label them
-3 will be x1
1 is y1
4 is x2
0 is y2
You will be using [tex]\frac{y2-y1}{x2-x1}[/tex]
Put the values into the equation
[tex]\frac{0-1}{4--3} =\frac{0-1}{4+3} =\frac{-1}{7}[/tex]
You get the same thing as the previous way.
Same answer
Visuals also included
I hope this helps and don't be afraid to reach out with further questions!

State if the triangles are similar. If so, state how you know they are.
Answer:
The triangles are similar
Step-by-step explanation:
Since EF ║ UT, m∠FUT = m∠EFU because alternate interior angles are congruent when lines are parallel.
m∠UDT = m∠EDF because vertical angles are congruetnt
Therefore ΔUDF is similar to ΔFDE because if two angles of a triangle are congruent to two angles of another triangle, then the triangles are similar.

A recipe requires 4 cups of flour to make 28 dinner rolls. How many cups of flour is needed to make 112 rolls?
Answer:
16 cups
Step-by-step explanation:
You have the ratio 4 cups = 28 dinner rolls. 28 * 4 = 112, so you know that if you multiply both sides of that equation by 4 you will get the number of cups of flout to make 28 dinner rolls:
4 cups = 28 dinner rolls
becomes
16 cups = 112 dinner rolls
so the answer is 16 cups
Answer:
16 cups of flour are needed to make 112 dinner rolls.
Step-by-step explanation:
28 divided by 4 is 7 which is the number of rolls for one cups of flour. Divide 112 by 7 and thats the amount of flour needed for 112 dinner rolls. You can also multiply 28 4 times since 4 can go into 16 when multiplied.

Which type of triangle is formed by joining three line segments with the following lengths?
8 in, 8 in, 8 in
Answer:
Equilateral Triangle
Step-by-step explanation:
How would the average rate of change over years 1 to 5 and years 6 to 10 be affected if the population increased at a rate of 8%?
Answer:
(A): As year increases the number of pikas reduces.
(B): As year increases the number of pikas increases as opposed to when the rate reduces.
Step-by-step explanation:
See comment for complete question
Given
[tex]a = 144[/tex] --- Initial Population
[tex]r = 8\%[/tex] --- rate
(A) WHEN THE RATE DECREASES
First, we need to write out the function when the population decreases.
This is given as:
[tex]f(x) = a(1-r)^x[/tex]
Substitute values for a and r
[tex]f(x) = 144(1-8\%)^x[/tex]
Convert % to decimal
[tex]f(x) = 144(1-0.08)^x[/tex]
[tex]f(x) = 144(0.92)^x[/tex]
Next, we calculate the average rate of change for both intervals using:
[tex]Rate = \frac{f(b) - f(a)}{b-a}[/tex]
For 1 to 5:
[tex]Rate = \frac{f(5) - f(1)}{5-1}[/tex]
[tex]Rate = \frac{f(5) - f(1)}{4}[/tex]
Calculate f(5) and f(1)
[tex]f(x) = 144(0.92)^x[/tex]
[tex]f(1) = 144*0.92^1 =144*0.92=132.48[/tex]
[tex]f(5) = 144*0.92^5 =144*0.66=95.04[/tex]
[tex]Rate = \frac{95.04 - 132.48 }{4}[/tex]
[tex]Rate = \frac{-37.44}{4}[/tex]
[tex]Rate = -9.36[/tex]
For 6 to 10:
[tex]Rate = \frac{f(10) - f(6)}{10-6}[/tex]
[tex]Rate = \frac{f(10) - f(6)}{4}[/tex]
Calculate f(6) and f(10)
[tex]f(x) = 144(0.92)^x[/tex]
[tex]f(6) = 144*0.92^6 =144*0.61=87.84[/tex]
[tex]f(10) = 144*0.92^{10} =144*0.43=61.92[/tex]
[tex]Rate = \frac{61.92-87.84}{4}[/tex]
[tex]Rate = \frac{-25.92}{4}[/tex]
[tex]Rate = -6.48[/tex]
So, we have:
[tex]Rate = -9.36[/tex] for year 1 to 5
This means that the number of pikas reduces by 9.36 yearly
[tex]Rate = -6.48[/tex] for year 6 to 10
This means that the number of pikas reduces by 6.48 yearly
So, we can say that, as year increases the number of pikas reduces.
(B) WHEN THE RATE INCREASES
First, we need to write out the function when the population decreases.
This is given as:
[tex]f(x) = a(1-r)^x[/tex]
Substitute values for a and r
[tex]f(x) = 144(1+8\%)^x[/tex]
Convert % to decimal
[tex]f(x) = 144(1+0.08)^x[/tex]
[tex]f(x) = 144(1.08)^x[/tex]
Next, we calculate the average rate of change for both intervals using:
[tex]Rate = \frac{f(b) - f(a)}{b-a}[/tex]
For 1 to 5:
[tex]Rate = \frac{f(5) - f(1)}{5-1}[/tex]
[tex]Rate = \frac{f(5) - f(1)}{4}[/tex]
Calculate f(5) and f(1)
[tex]f(x) = 144(1.08)^x[/tex]
[tex]f(1) = 144(1.08)^1 = 144*1.08= 155.52[/tex]
[tex]f(5) = 144(1.08)^5 = 144*1.47= 211.68[/tex]
[tex]Rate = \frac{211.68 - 155.52}{4}[/tex]
[tex]Rate = \frac{56.16}{4}[/tex]
[tex]Rate = 14.04[/tex]
For 6 to 10:
[tex]Rate = \frac{f(10) - f(6)}{10-6}[/tex]
[tex]Rate = \frac{f(10) - f(6)}{4}[/tex]
Calculate f(6) and f(10)
[tex]f(x) = 144(1.08)^x[/tex]
[tex]f(6) = 144(1.08)^6 = 228.52[/tex]
[tex]f(10) = 144(1.08)^{10} = 310.89[/tex]
[tex]Rate = \frac{310.89-228.52}{4}[/tex]
[tex]Rate = \frac{82.37}{4}[/tex]
[tex]Rate = 20.59[/tex]
So, we have:
[tex]Rate = 14.04[/tex] for year 1 to 5
This means that the number of pikas increases by 14.04 yearly
[tex]Rate = 20.59[/tex] for year 6 to 10
This means that the number of pikas increases by 20.59 yearly
So, we can say that, as year increases the number of pikas increases as opposed to when the rate reduces.

Answer:
2.4 or 2[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
Let's set this up:
We have 3/1[tex]\frac{1}{4}[/tex]
That's also 3/1.25
For division, we don't divide if there is a fraction, so we move the decimal place over to the right for both the numbers
300/125
Then you long divide as normal:
And it's really hard to show how to long divide on a computer so I'm just going to go ahead and assume you know how to.
But the answer to that would be 2.4 or 2[tex]\frac{2}{5}[/tex]

Tonya and Mario are asked to use a pan balance to find the mass of the same rock. Tonya finds the rock's mass to be 680 grams. Mario finds the rock's mass to be 672 grams. Which is the best explanation for the difference in their measurements?
A. Either Mario or Tonya measured the mass of the rock incorrectly on the pan balance.
B. The rock was cold when Tonya measured its mass and hot when Mario measured in mass.
C. The rock changed in size between the time Tonya measured it and the time Mario measured it.
D. The rock broke before Mario measured it. So the mass of the two pieces together was less than when Tonya measured it. PLEASEEEE HELPPP
Solve the triangle. Round decimal answers to the nearest tenth.
Answer:
x = 5.7 y = 9.4
m∠H = 31°
Step-by-step explanation:
cos of an angle = adjacent side/hypotenuse
and sine of an angle = opposite side/hypotenuse
cos 59 = x/11 and sin 59 = y/11
11 cos 59 = x 11 sin 59 = y
x = 5.7 y = 9.4
m∠H = 90 - 59 = 31°
You need to memorize the definitions of all the trig functions and then these types of problems will be easy for you.
[tex]x=5.7[/tex], [tex]y=9.4[/tex] and ∠[tex]H[/tex][tex]=31[/tex]° is the solution of the triangle.
What is trigonometric ratio?
Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the respective angle.
The basic trigonometric ratios formulas are given below :
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
What is the sum of angle of triangle?The sum of angles of a triangle equals the straight angle (180 degrees, π radians, two right angles, or a half-turn)
According to question,
In Δ FGH ,
∠G = 59°
Hypotenuse of triangle = 11
Base of triangle according to the ∠G = x
Perpendicular of triangle according to the ∠G = y
Now,
Cosθ = [tex]\frac{Base}{Hypotenuse}[/tex]
[tex]Cos[/tex] 59° = [tex]\frac{x}{11}[/tex]
[tex]x[/tex] [tex]=11[/tex]× [tex]0.515[/tex] ( Cos59° = [tex]0.515[/tex] )
x [tex]=5.7[/tex]
Sinθ = [tex]\frac{Perpendicular}{Hypotenuse}[/tex]
[tex]Sin[/tex] [tex]59[/tex]° [tex]=\frac{y}{11}[/tex]
[tex]y=11[/tex] * 0.857
y [tex]=9.4[/tex]
According to the sum of angle of triangle
∠F + ∠G +∠H = 180°
90° + 59° + ∠H = 180°
∠H = 180° - 90 -59
∠H = 31°
Hence,[tex]x=5.7[/tex], [tex]y=9.4[/tex] and ∠[tex]H[/tex][tex]=31[/tex]° is the solution of the triangle.

(HELP MEH PLZZ)
Answer:
1 1/3 - 5/6 = 1/2
Step-by-step explanation:
First we will need to make a common denominator on both sides, so since we have the second side divided in six, we can do the same to the first side as shown;
1/3 = 2/6
now this will help us a lot, now all we have to do is take what we can out of the fraction (2/6) out of the first side so it is equal to 0, NOTE this is not a professional way to do it but it helps me a lot;
5/6 - 2/6 = 3/6
this makes it easy all of a sudden, cause now its in a simpler form, we can tell this because we know that 3/6 is equal to 1/2, so now all we have to do is take 1/2 from our 1 that we are left over with, and VWOLA;
1 - 1/2 = 1/2
GRAND TOTAL;
1 1/3 - 5/6 = 1/2
(note: the space between the 1 and the 1/3 indicates that they are two separate numbers, so you dont have to put the 'and' there)
