Answer:
4
Step-by-step explanation:
to find the mean you add up all of the numbers and then divide by the numbr of numbers there are. So to add them all up that will be 3+5+0+4+7+5+5+3=32
so then you divide 32 by 8 which equals 4.
So therefore your answer is 4.

o 0 If a triangle has angle measurements of 60 and 70°, what is the measure of the third angle? What kind of triangle is this? Acute, Right, or Obtuse? Explain how you solve this problem.
Answer:
→ 50°
→ Acute triangle
Step-by-step explanation:
the measure of the third angle = 180 - (60 + 70) = 180 - 130 = 50°
definitions=======================================
Acute angle : it’s an angle that measures less than 90°.
Acute triangle: it’s a triangle with three acute angles.
………………………………………………………………………………………………
The measures of the angles in our triangle are respectively 60° , 70° , 50°
Thus ,it’s an acute triangle .
Find the value of y.
Answer:
94°Step-by-step explanation:
Find x
(180 - 36) : 2 =
72°
so angle 2x is 144°
sum of all interior angles = 720°
Find y
720 - 144 - 111 - 105 - 165 - 101 =

Step-by-step explanation:
Rewriting the equation in terms of equalling L
P = 2L + 3WSubtract 3W on both sides.
P - 3W = 2L + 3W - 3W2L = P - 3WDivide 2 on both sides
2L/2 = (P - 3W)/2L = (P - 3W)/2⇒ Option A

PLEASE HELP!! Madison is monitoring the temperature over several hours. Her data is shown in the table. She draws a best-fit line with the equation y= -6.2+64 where x represents the number of hours that have passed and y represents the temperature.
Describe the meaning of the slope and the y-intercept in this context. Answer in complete sentences.
Using linear function concepts, we have that the interpretations are given as follows:
The slope of -6.2 means that the temperature falls 6.2 ºF every hour.The y-intercept of 64 means that the initial temperature was of 64 ºF.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, we have that the function is given by:
y = -6.2x + 64.
Hence:
The slope of -6.2 means that the temperature falls 6.2 ºF every hour.The y-intercept of 64 means that the initial temperature was of 64 ºF.More can be learned about linear function concepts at https://brainly.com/question/24808124

8x+4=28 question i want some one to solve this for me
Answer:
x = 3
Step-by-step explanation:
8x + 4 = 28
subtract 4 from both sides
8x + 4 - 4 = 28 - 4
8x = 24
divided both sides by 8
8x / 8 = 24 / 8
x = 3

Find the mistake in the following set of steps in a student’s attempt to solve 5x+2≥x+2/5, for x. What is the correct solution set?
5x+2≥x+2/5
5(x+2/5)≥x+2/5 (factoring out 5 on the left side)
5≥1 (dividing by (x+2/5))
So, the solution set is the empty set.
Answer: x ≥ [tex]\frac{-2}{5}[/tex]
Step-by-step explanation:
I cannot see what the student did wrong in your question, so I solved for x in the equation...
[tex]5x + 2[/tex] ≥ [tex]x + \frac{2}{5}[/tex]
1. subtract x from both sides
4x + 2 ≥ [tex]\frac{2}{5}[/tex]
2. subtract 2 from both sides to isolate 4x
4x ≥ [tex]\frac{-8}{5}[/tex]
3. divide both sides by 4
x ≥ [tex]\frac{-2}{5}[/tex]

I need help to find the measures and equation pls.
Answer:
Equation: 7x + 8x = 180
x = 12
∠CBA = 84
∠CFH = 96
Step-by-step explanation:
We can see that ∠CBA = ∠CFE and ∠CBD = ∠CFH.
We know that the sums of two angles on a straight line are going to be equal to 180.
∠CBA = 7x
∠CFH = 8x
To find the value of x, we must do the following:
7x + 8x = 180
15x = 180
15x/15 = 180/15
x = 12
Now we just substitute to find the angle measures:
∠CBA = 7 · 12 = 84
∠ CFH = 8 · 12 = 96

Malika is making lemonade to sell at a school fundraiser:
She purchased a new lemon squeezer for $9.00.
The cost of the ingredients for each serving of lemonade is $1.50.

Write an inequality that represents the minimum number of servings of lemonade, x, Malika must sell for the money from her sales to exceed the total cost of making the lemonade.
Answer:
1.50x>2.25x+9.00
Step-by-step explanation:
Because the 1.50 has to go their because 2.25 is greater than 1.50, the 9.00 is at the end because their is not a variable. How to know were theh variables go is the each.
She purchased a new lemon squeezer for $9.00.

We have given that,
Malika is making lemonade to sell at a school fundraiser.
What is the total cost?The total cost is the addition of all the costs.
Malika must sell for the money from her sales to exceed the total cost of making the lemonade.
Because the 1.50 has to go there because 2.25 is greater than 1.50, the 9.00 is at the end because there is not a variable.
How to know where variables go is the each.
She purchased a new lemon squeezer for $9.00.
The cost of the ingredients for each serving of lemonade is $1.50.
