Answer:
Y and Z.
Step-by-step explanation:
My reasoning is that because scalene triangles have all different measurements, Y and Z would be correct since they have multiple different measurements. X is an obtuse triangle, while W is a right triangle, so that leaves Y and Z.
===========================================================
Explanation:
Triangle W is a right triangle because of the square marker. This angle is 90 degrees, also known as a right angle.
Acute triangles on the other hand must have all angles smaller than 90 degrees. This rules out triangle W.
The missing angle of triangle X is 180-40-35 = 105 degrees, showing this triangle is obtuse. Obtuse triangles have exactly one angle that is between 90 and 180. Therefore, we rule out triangle X as well.
Triangles Y and Z are acute because all angles are smaller than 90 degrees. For triangle Y, the missing angle is 180-70-80 = 30. For triangle Z, the missing angle is 180-65-45 = 70 degrees.
---------------
That takes care of the "acute" portion. Now onto the "scalene" part.
All four triangles shown are scalene. Why? Because all three sides are different lengths, as indicated by the different tickmarks.
However, we ruled out triangles W and X since they weren't acute.
Therefore, triangles Y and Z are both acute and scalene.Related Questions

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought 3 magazines, how many books did he buy?
The equation that models the problem is 3.95m + 8.95b = 47.65, where m is the number of magazines and b is the number of books.
__ books
Answers
Answer:
4 books
Step-by-step explanation:
Our problem here is:
[tex](3.95)3+8.95b=47.65[/tex]
So we have to find B, and that will be our answer (the number of books).
1. Simplify the expression
[tex]3.95\cdot 3+8.95x=47.65[/tex]
Combine like terms:
[tex]11.85+8.95x=47.65[/tex]
2. Group all constants on the right side of the equation
[tex]11.85+8.95x=47.65[/tex]
Subtract from both sides:
[tex]11.85+8.95x-11.85=47.65-11.85[/tex]
Group like terms:
[tex]8.95x+11.85-11.85=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=47.65-11.85[/tex]
Simplify the arithmetic:
[tex]8.95x=35.8[/tex]
3. Isolate the x
[tex]8.95x=35.8[/tex]
Divide both sides by 8.95:
[tex]\frac{8.95x}{8.95}=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=\frac{35.8}{8.95}[/tex]
Simplify the arithmetic:
[tex]x=4[/tex]

Answers
Answer:
It is an acute triangle.
Two sides have the same length.
The third angle measures 70°.
Step-by-step explanation:
It is an acute triangle because all triangles are less than 90°.
Two sides have the same length because since we know that two angles, which would be the base angles are the same, then triangle must be isosceles.
180°-(40°+70°)= 110°

Answer: 108 ft³
Step-by-step explanation:
V= 4/3πr³
Facts:
Pi= 3
Diameter = 6
Step1; find the radius
Diameter is the length acaross the whole circle, but the radius is just 1/2 the circle. Therefore, if the diameter is 6, then the radius can be found by finding 1/2 of 6.
1/2 of 6= 1/2x6= 3.
R= 3
Step 2: Plug in the numbers (into the formula)
PEMDAS
(exponents go first)
(then multiply from left to right)
V= 4/3πr³
V= 4/3x3x3³
V= 4/3x3x (3x3x3)
V= 4/3x3x27
V= (4/3x3) x 27
V= 12/3x27
V= 4x27
V= 108
Volume= 108 ft³

4x - (2x - 2)= 10
Step 2: Combine like terms
2x -2 =10
Step 3: Add 2 to both sides of the equation
2x = 12
Step 4: Divide both sides by 2
x= 6
Now substitute x=6 into any of the equations given, I chose the bottom one.
Step 5: Plug in x=6 and solve
y= 2(6) -2
y= 12-2

Help. Where do I put the dot, should it be opened or closed, and what direction should the line face?
Answers
Answer: 5 with an open circle facing the right.
Step-by-step explanation:
First: you need to know the difference between closed and open circles. Closed means less than or equal to/ greater than or equal to while an open circle just means less than/ greater than.
Second: To know if it will be facing left or right is very simple. It is just if the number is increasing or decreasing in your problem. If increasing it goes right if decreasing it goes left. In this case, the number increases each day so it will face the right.
Third: To start the problem you subtract the number of shells she has already (34) by how many she needs (100) which is 66. then divide 66 by the number of seashells they get a day (12) which would give you 5.5
Fourth: I'm going to guess that you can't do decimals on the graph so all you have to do is put an open circle with the arrow facing the right meaning everything after this point, not including the number it is on.
Answer:
d ≥ 7
Step-by-step explanation:
A closed dot means you CAN use the number in the equality (greater than and equal to or less than and equal to). An OPEN dot means it's just greater than or less than, no equal to. Positive numbers GROW to the right so if the line is going that way it means greater than or greater than and equal to. The same is true for the left side. The left side makes numbers get SMALLER which means less than or less than and equal to. Your problem has a closed dot and an arrow to the right so the inequality is d ≥ 7.

City R has a temperature of −2 °F. City S has a temperature of −6 °F.
Use the number line shown to answer the questions:
Part A: Write an inequality to compare the temperatures of the two cities. (3 points)
Part B: Explain what the inequality means in relation to the positions of these numbers on the number line. (4 points)
Part C: Use the number line to explain which city is warmer. (3 points)
Answers
part a: –2°F > –6°F
part b: the inequality is representing the temperatures of city R and city S, comparing the difference in their temperatures.
part c: (marking city R at –2 on the number line and marking city S at –6 on the number line), using the number line to show the values of the city temperatures, city R is warmer because it is closer to 0 while city S is farther from zero and in the case that these are negative temperatures, the temperature closest to zero is the warmest.
Part B- this is an inequality because it is comparing the temperature difference. -2 is greater than -6 because it is a warmer temperature. The higher the negative number the colder it is, the lower the negative number is or the closer
Part C- City R is warmer because it is -2 degrees F and the other city is -6F. The closer you get to zero when working with negative numbers the bigger the number is. This is because number lines read from left to right, just like a book. -2 is warmer than -6 because it is closer to zero and it is closer to become a positive number than -6 is.

The contents of two boxes are shown below. What is the probability of drawing a vowel from box 1 and an even number from box 2?

Box 2: 1, 2, 3, 4, 5, 6, 7, 8, 9
PLEASE SHOW ALL YOUR WORK AND GET 30 POINTS !!!!!!! THANK YOU
Answers
So, there are 2 vowels in box 1, A and E. Next, there are 4 even numbers in box 2, 2, 4, 6, and 8. Now, lets set up our equation. The equation will be amount/total amount. The equation will be 2/5 x 4/9, and the answer will be 8/45.
Answer:
vowel = 2/5
even number = 4/9
Step-by-step explanation:
vowel:
total of all letters in the box= 5
cound total number of vowels in the box = 2
[tex]\frac{2}{5}[/tex] because out of the 5 letters there is 2 vowels so overall you have a [tex]\frac{2}{5}[/tex]chance of pulling out a vowel.
Same logic for the even numbers one.
Even numbers:
total amount of numbers in the box: 9
total amout of even numbers: 4
[tex]\frac{4}{9}[/tex] because you have 9 numbers in total and you want the chnce of finding an even number. That means you need to put the amout of even numbers on top of the fraction and the total amount below.
OVERALL:
simple way of remembering it is:
p = total amout of the thing you want the probability of finding (in this case even numbers or vowels)
t = total amout of all options in the box (or any container)
[tex]\frac{p}{t}[/tex]

Step-by-step explanation:
See picture of all side values in the three measurement forms
Answer: I think this is right but I'm not 100 percent sure
26.4 km, 264 hm, 2640 dam
Step-by-step explanation:
Well, permitter is adding all lengths together.
Which is 5 km + 62 hm + 62 hm + 900 dm
Assuming hm stands for Hectometer, I will divide 62/10 = 6.2
Now we are left with the equation 5 km + 6.2 km + 6.2 km + 900 dam
Since 100 dm = 1 km, we will divide 900 dm by 100 which is 9 km
Lastly, we are left of with:
5 + 6.2 + 6.2 + 9 = 26.4 km
Now I will quickly covert everything into the other 2 measurements
26.4 km = 264 hm (10x)
26.4 km = 2640 dam (100x)
