Answer: 12 bracelets
Step-by-step explanation:
I am assuming you meant to write “Brianna has four pink bracelets, 1/3 of all her bracelets are pink. How many bracelets does Brianna have?”
If that’s what you mean to write proceed on my writing.
Write out what you know
4 pink bracelets= 1/3 of her bracelets
Equation:
4+4+4=12 bracelets
1/3+1/3+1/3=3/3=100% of her collection
what is 50% of the number?
explain how you worked this out
What is the missing statement in the proof?
∠1 ≅ ∠2
a ⊥ b
a ∥ b
∠1 ≅ ∠4
The missing statement in the proof is ∠1 ≅ ∠4.
Solution:
(1) Given ∠1 ≅ ∠2
(2) ∠1 and ∠4 are vertical angles.
Vertical angle theorem:
If two angles are vertically opposite then they are congruent.
By vertical angle theorem,
⇒ ∠1 ≅ ∠4
(3) Transitive property of congruence:
If A = B and B = C, then A = C.
From (1) and (2), ∠2 ≅ ∠4.
(4) If two lines and a transversal form congruent corresponding angles, then the lines are parallel.
Therefore line a || line b.
⇒ a || b.
Hence the missing statement in the proof is ∠1 ≅ ∠4.
The statements that best describes its construction is:
There is one possible triangle with these side lengths.
We know that with the help of three given angle measures infinite number of triangles could be constructed with different side lengths and with the help of three gives side lengths a unique triangle is constructed.
Here we are given three side lengths as:
8 centimeters, 13 centimeters, 15 centimeters.
This means that there is only one such triangle possible.
37 is greater than 35, so round 37 up to 40.
Ally records the time as 40 minutes. Please answer I’ll give 20 points
Answer:
Yes, you are correct, if it is 37 minutes and you are supposed to round, you round up.
Step-by-step explanation:
Miguel forgot to choose the intervals.
Miguel forgot to create the frequency table.
Miguel forgot to create the title.
Miguel forgot to put spaces between the bars.
Answer:
Miguel forgot to create the title
Step-by-step explanation:
As given in diagram:
The histogram has intervals of 1-10,11-20,21-30,31-40 and 41-50.
Also the frequency in labelled on the y-axis from 0-7.
As there can be no space between the bars in a histogram, hence the only thing missing in the histogram is the title.
The title of histogram describes the information plotted in histogram!
Answer:
The correct option is 3.
Step-by-step explanation:
Given that Miguel made a histogram to show the ages of all the participants involved in a fund-raiser.
We need to find the part of the histogram that Miguel forget to create.
The intervals of histogram are mentioned in the given histogram. 1-10, 11-20, 21-30, 31-40, 41-50.
Frequency for each interval is cleared from the given histogram and frequency table is not a part of histogram.
The title of histogram is missing, so Miguel forgot to create the title.
In histogram, there is no space between the consecutive bars.
Therefore the correct option is 3.
