Si dividimos una pizza el cuarto partes iguales y dividimos una de estas partes en dos partes iguales¿Cuál es la fracción que representa una de estas partes más pequeñas?
Answers
Answer:
[tex]\frac{0.5}{4}[/tex]
Step-by-step explanation:
An entire pizza would be represented by the percentage of 100% or the fraction [tex]\frac{100}{100}[/tex]. If we divide this pizza into 4 equal parts that would make one slice a fraction represented as [tex]\frac{25}{100}[/tex] or simplified to [tex]\frac{1}{4}[/tex]. If we now divide this one slice into two equal parts we would divide that fraction by 2 which would give us a new fraction, which would be [tex]\frac{0.5}{4}[/tex]. Represented as a percentage this would mean that this slice is 12.5% of the entire pizza.

A. -2 ≤ x ≤ 5
B. x ≤ -2 OR x ≥ 5
C. x ≤ -15 OR x ≥ 12
D. x ≥ 5
Thank you!
Answers
Answer:
B
Step-by-step explanation:
We have the compound inequality:
[tex]5x+7\leq-3 \text{ or } 3x-4\geq 11[/tex]
Since this is an “OR” inequality, we can solve each inequality individually. So:
1)
We have:
[tex]5x+7\leq-3[/tex]
Subtract 7 from both sides:
[tex]5x\leq -10[/tex]
Divide both sides by 5:
[tex]x\leq-2[/tex]
So, the first solution is above.
2)
We have:
[tex]3x-4\geq 11[/tex]
Add 4 to both sides:
[tex]3x\geq15[/tex]
Divide both side by 3:
[tex]x\geq5[/tex]
Our second solution is above.
Therefore, our solution is:
[tex]x\leq -2 \text{ or } x\geq5[/tex]
Since our original inequality is “OR,” our solution set remains an “OR.”
Hence, our answer is B.

If the sum of a triangle equals 180 degrees we’ll go off of that by doing this.

3.Perimeter is 45 units since each side is 15 units.
Step-by-step explanation:
x-5=3x-45
-5=2x-45
40=2x
x=20
So AB is 15 and AC and BC is also 15 since it is equilateral. 15+15+15=45 The perimeter is 45 units.

Check the box labeled Show Segment Parallel to BC. Notice that DE intersects two sides of triangle ABC creating a smaller triangle, triangle ADE. How is triangle ADE related triangle ABC to ? How do you know?
Answers
Answer: Since corresponding angles of parallel lines cut by a transversal are congruent, ADE = ABC and AED = ACB. So, based on the AA criterion for similarity, ABC ~ ADE.
Step-by-step explanation: Sample answer from Edmentum! Hope It helps :)
The triangle ADE is similar to the triangle ABC.
What is a similar triangle?Similar triangles are triangles whose corresponding lengths are not equal to each other, but their corresponding angles are equal.
The relation between triangle ADE and ABC is shown below:It is given that the line segment DE is parallel to BC.
Since it is parallel to each other, we can say that the angles formed on both the line segments are equal to each other since they are corresponding angles. Angle A is common to both the triangles.
Therefore, we can say that the two triangles are similar because all the angles are the same in each triangle.
Therefore, we have found out that the triangle ADE is similar to the triangle ABC.

-11
Answers
Answer:
x = -11
Step-by-step explanation:
Well the two equations add up to 180 because they are a linear pair.
x + 56 + x + 146 = 180 (collect like terms)
2x + 202 = 180 (subtract 202 on both sides)
2x = -22 (divide by 2 on both sides)
x = -11
Hope this helps ya!!
(Combine like terms)
2x+202=180 (Subtract 202 to both sides because we want the x isolated)
2x+202=180
-202 -202
2x=-22 (Divide)
2 2
X=-11

A small company manufactures a certain item and sells it online. The company has a business model where the cost C, in dollars, to make x items is given by the equation

Graph the cost and revenue equations on the xy-coordinate plane provided. Select the "Line" tool. Plot two points, then a line will connect the points.

Step-by-step explanation:
The break-even point is on both curves. The y-intercept can be used for the other point in each case.
The break-even point is where cost and revenue are the same:
20/3x +50 = 10x
50 = 10/3x . . . . . . . . subtract 20/3x
15 = x . . . . . multiply by 3/10
r = c = 10(15) = 150 . . . . for x = 10
Two points you can use for graphing the lines are ...
cost: (0, 50) and (15, 150)

A manufacturer claims that the mean lifetime of its lithium batteries is 1200 hours. A homeowner selects 25 of these batteries and finds the mean lifetime to be 1180 hours with a standard deviation of 80 hours. Test the manufacturer's claim. Use ΅ = 0.05. Round the test statistic to the nearest thousandth.
Answers
Answer:
Since p is > α we fail to reject the Null as the result is not significant at α = 0.05
Step-by-step explanation:
Given that:
Mean lifetime (m) = 1200
Sample size (n) = 25
Sample mean (x) = 1180
Standard deviation (s) = 80
α = 0.05
The null hypothesis :
H0 : m = 1200
Alternative hypothesis : m ≠1200
The t statistic :
(x - m) / (s/√n)
(1180 - 1200) / (80 / √25)
-20 / (80/5)
= - 1.250
P value = 0.10565 ( p value calculator)
Reject Null hypothesis if p > α
At α = 0.05
Since p is > α we fail to reject the Null as the result is not significant at α = 0.05
