Step-by-step explanation:
Negative numbers have the least value and (-1) is the greatest negative value
So, d is arranged in least to greatest order
d) -5 , - 2 , 1 , 3 , 4
Answer:
The answer is D.
Step-by-step explanation:
D is the one that has the order from least to greatest.
Explain why triangle ABC is similar to triangle CFE
Answer:
It's exactly the same, except the size
Step-by-step explanation:
Answer:
They are similar because if you look at the length of 2 of the sides that you know
Triangle ABC has side length 1 and 2 or 1:2
CFE has sides length 2 and 4 or 2:4 and 2:4 can also be written as [tex]\frac{2}{4}[/tex] which is a fraction, and fractions can be simplified to 1:2.
So they are similar but just one is bigger then the other.

help its for math will give brainly Find the area of the hexagon.
Answer:
the area of the hexagon is 68 cm²
Step-by-step explanation:
Let us observe the image a little, we can find the area of the hexagon equals to the area of the large rectangle minus 4 small triangles surrounding the hexagon. The area of the rectangle is 8 × 12 is 96 cm². The area of 1 small triangle is 4 × 3.5 ÷ 2 = 7, there are 4 triangles, so the total area is 4 × 7 = 28. So the hexagon's area is 96 - 28 = 68 cm²

Answer:
x=54, acute scalene triangle
Step-by-step explanation:
1st Question:
Triangle SRT has two congruent sides, making it an isosceles triangle.
In isosceles triangles, the two base angles are congruent.
This means that in the question, ∠SRT equals ∠STR, so let's call them both x.
The sum of the interior angles of a triangle add to 180, so
∠RST+∠SRT+∠STR=180
Substitute ∠RST for 72 and ∠SRT+∠STR for x
72+2x=180
2x=108
x=54
2nd Question:
Again, using the sum of the interior angles of a triangle, we can say
42+88+∠DFE=180
∠DFE=50
All the angles in the triangle are less than 90°, meaning they are all acute. Also, none of the sides are labeled as congruent, so it is an acute scalene triangle

You and a friend are trying to decide whether going to the movie theater or renting a film to watch at home would cost less. At Theater
Y, the cost of a ticket for young adults ages 10-18 is $7.75. A medium drink costs $2.50 and a small popcorn costs $2.50. Conversely,
it costs $4.50 to rent a movie, $1.50 for a 2 liter of cola, and $2.00 for a bag of microwave popcorn. Which option would cost less and
by how much?
Home by $17.50
Theater Y by $8.00
Theater Y by $17.50
Home by $8.00
Answer:
Home by $17.50
Step-by-step explanation:
Home by 17.50 because when going to the theater you have to consider all the costs of everything you will be purchasing so there will be 2 tickets for yourself and your friend 2 drinks and 2 small popcorns when you add all of these up it will look like this 7.75+7.75+2.50+2.50+2.50+2.50 = 25.50 then I will subtract this from the at home cost so 25.50 - 4.50 - 1.50 - 2.00 = 17.50 So it's cheaper home by 17.50

The slope of a line is 2/5
What is the slope of any line perpendicular to this line? (If an answer is undefined, enter UNDEFINED.)
Step-by-step explanation:
Explanation:
First, we must solve the equation for y to determine the slope: y = 2x + 3/2
By looking at the coefficient in front of x, we know that the slope of this line has a value of 2. To fine the slope of any line perpendicular to this one, we take the negative reciprocal of it:
slope = m , perpendicular slope = – 1/m
slope = 2 , perpendicular slope = – 1/2
Answer:
the slope would be -5/2
Explanation:
the perpendicular slope of a line is the negative reciprocal and the negative reciprocal of 2/5 is -5/2

Answer:
7) circumference = 11.78 ft
8) arc NMP = 198° or 27.63 ft
Step-by-step explanation:
7) circumference = πd = (3.14) (3 3/4) = 11.78 ft
8) radius = 8 ft
diameter = 2 x 8 = 16 ft
arc NM + arc QP = 360° - 162° - 162° = 36°
arc NM = arc QP because they are arcs of vertical angles.
arc QP = 18°
arc NMQ = 180°
arc NMP = 180° + 18° = 198°
circumference = πd = (3.14)(16) = 50.24 ft
(198°/360°)(50.24) = 27.63 ft

Answer: 10 < x < 60, or x is from 10 to 60
Step-by-step explanation: A domain of a graph consists of all of the input values shown on the x-axis while the range consists of all of the output values shown on the y-axis. Since the question asks to find the domain, you should look at the values of the graph from left to right. The domain includes all real numbers. Notice the black horizontal line on the graph and match up the beginning of it and the end of it with the values on the x-axis. The line begins at an x-value of 10 and ends at an x-value of 60; therefore, the domain (x-values) is from 10 to 60.

The steps below show the incomplete solution to find the value of m for the equation 5m − 2m + 4 = −1 + 12: Step 1: 5m − 2m + 3 = −1 + 12 Step 2: 5m − 2m + 3 = 11 Step 3: 3m + 3 = 11 Which of these is most likely the next step? (5 points) a 3m = 3 b 3m = 8 c 3m = 16 d 3m = 18
Given:
Consider the equation is:
[tex]5m-2m+3=-1+12[/tex]
Some steps of the solution are given.
To find:
The next step of the solution.
Solution:
Step 1: The given equation is:
[tex]5m-2m+3=-1+12[/tex]
Step 2: Simplifying right hand side.
[tex]5m-2m+3=11[/tex]
Step 3: Simplifying left hand side.
[tex]3m+3=11[/tex]
These steps are already given. So, the next step is:
Step 4: Subtracting 3 from both sides.
[tex]3m=8[/tex]
Therefore, the correct option is (b).
what is the radius of the cylinder
Answer:
5.99
Step-by-step explanation:
brainliest pwease??
The volume of a cylinder can be found with the following equation
[tex]V = r^2h\pi[/tex]
After inputting the known information we get
[tex]980\pi = r^220\pi \\\\[/tex]
Which simplifies to
radius = 7 or (-7)
For proof's sake, we can try the equation again with the known radius
[tex]980\pi = r^220\pi \\980\pi = (7^2)20\pi \\980\pi = (49)20\pi \\980\pi = 980\pi \\[/tex]
And because the radius is being squared, it can either be negative or positive.

Answer:
Same y-intercept
Step-by-step explanation:
They have the same y-intercept of 2
look a y intercept is where the function crosses the y axis or when x is 0
In the chart y=2 when x =2 meaning a y intercept of 2
in the graph u can see the line going through the y intercept at (0,2)
So they have the same y-intercept
