Answer:
explanation will answer.
Step-by-step explanation:
To convert this fraction to a decimal, just divide the numerator (35) by the denominator (64). So, 35 / 64 = 35 ÷ 64 = 0.546875. Approximated Values: 35 / 64 = 0.5 rounded to 1 significant figure. 35 / 64 = 0.55 rounded to 2 significant figures. 35 / 64 = 0.547 rounded to 3 significant figures.

d. What number is 6% of 30?
Answer:
1.8
Step-by-step explanation:
to find any percent of a number, multiply that number by the percent x.(the percentage is x/100 since percents are just fractions with a hidden denominator of 100), and 30*(6/100) is 18/10, which is just 1.8.

19. Ken bought 8 markers and 20 pens. Each marker cost $2.45. He gave the cashier $100 and received $26 change. What was the cost of each pen?
Answer:
Each pen costs $2.72
Step-by-step explanation:
100 - 26 = $74 spent total
8 x 2.45 = $19.60 spent on markers
74 - 19.60 = $54.40 spent on pens
54.40/20 = $2.72 per pen

10.Is 3/4 equivalent to 45/70?
When comparing fractions, you can multiply or divide to find equivalent fractions.
Number 1: If I were to multiply 5 to 45, I would have to do the same to the numerator of the fraction. 45/5 = 9. So we know now that 5 times 9 equals 45. Lets do that to the numerator also. 4 times 9 equals 36 so 4/5 times nine is 32/45.
So yes, this would be equivalent.
Number 2: 7/8 times 4 equals 28/32
Yes, this would be equivalent.
Number 3: 10 times 10 is 100, 1 times ten is NOT 30.
No, this would not be equivalent.
Number 4: 8 times 4 equals 32, 6 times 4 equals 24.
Yes, this would be equivalent.
Number 5: 30/5 equals 6. 70/8 is NOT 6.
No, this would not be equivalent.
Number 6: 24/2 equals 12. 100/3 is not 12.
No, this would not be equivalent.
Number 7: 30/2 is 15. 60/10 is NOT 15.
No, this would not be equivalent.
Number 8: 20/1 equals 20. 100/5 is also 20.
Yes, this would be equivalent.
Number 9: 20/5 equals 4. 30/6 is not 4.
No, this would not be equivalent.
Number 10: 45/3 is 15, 70/4 is NOT 15.
No, this would not be equivalent.

In triangle ABC, AB=BC, AC=10cm. From point D, which is in the middle of AB, perpendicular bisector DE is drawn to side BC and intersects it at point E. A segment is then drawn from E to A. The perimeter of triangle ABC is equal to 40 cm. Find the perimeter of △AEC.
Answer:
Step-by-step explanation:
We are given that the perpendicular bisector of side AB of ∆ABC intersects side BC at point D.
this means that side AE=BE.
Also, we could clear; ly observe that
ΔBED≅ΔAED
( since AE=BE, side ED common, ∠BED=∠AED
so by SAS congruency, the two triangles are congruent)
Now we are given that:
the perimeter of ∆ABC is 12 cm larger than the perimeter of ∆ACD.
i.e. AB+AC+BC=AC+AD+CD+12
AB+BC=AD+CD+12
as AD=BD
this means that AD+CD=BD+CD=BC
AB+BC=BC+12
AB=12
mark as brainliest
The perimeter of 40 cm. and lengths of two sides of ∆ABC where side AC is 10 cm gives;
The perimeter of ∆AEC is 25 centimeters How can the perimeter of the formed ∆AEC be found?Given:
AB = BC
AC = 10 cm.
The perimeter of ∆ABC = 40 cm.
Therefore;
∆ABC is an isosceles triangle
AB + BC + AC = 40
AB + AB + 10 = 40 by substitution property of equality
2 × AB = 40 - 10 = 30
AB = 30 ÷ 2 = 15AB = BC = 15 cm.
Using the rule of cosines, we have;
10² = 15² + 15² - 2×15×15 × cos(A)cos(A) = (15² + 15² - 10²) ÷ (2×15×15)
A = arccos (350 ÷ 450) ≈ 51.06°<BED ≈ 180° - (90° + 51.06°) = 38.94°
DB = AB ÷ 2
Therefore;
DB = 15 ÷ 2 = 7.5From the rule of sines, we have;
DE/sin(51.06°) = 7.5/sin(38.94°)DE = 7.5/sin(38.94°) × sin(51.06°) ≈ 9.28
According to Pythagorean theorem, we have;
BE ≈ √(7.5² + 9.28²) ≈ 11.93Similarly, we have;
AE ≈ √(7.5² + 9.28²) ≈ 11.93EC ≈ 15 - 11.93 = 3.068
Perimeter of ∆AEC = AE + EC + AC
Which gives;
The perimeter of ∆AEC = 11.93 + 3.068 + 10 ≈ 25
The perimeter of ∆AEC = 25 cmLearn more about the rule of sines and cosines here:

7.30. Julie wants to give a 45 -minute speech, and she speaks 120 words per minute. Her written notes contain 500 words per page. How many pages should she prepare?
Answer:
10.8 pages must be prepared
Step-by-step explanation:
We first have to figure out how many words Julie would be able to say in 45 minutes. Since she can say 120 words per minute, she can speak 120*45 or 5400 words total.
We also know that Julie can write 500 words per page. Since she has 5400 words total, she needs to prepare 10.8 pages total (5400 divided by 500). If you are looking for a whole number answer, Julie needs at least 11 pages to write her complete speech.
Answer:
The number of pages she should prepare is 10.8 pages.
Step-by-step explanation:
Given:
Julie wants to give a 45 -minute speech, and she speaks 120 words per minute.
Her written notes contain 500 words per page.

Sports magazine: 9, 21, 15, 14, 25, 26, 9, 19, 22, 30 Political magazine: 31, 22, 17, 5, 23, 15, 10, 20, 20, 17
Answer:
I also don't know so I am sorry I need point
Answer:
On comparing the center i.e. mean we get that the sports magazine 19 uses more words than a political magazine 18 but they are almost the same because their difference is only 1. The variance of sports magazines 5.8 is greater than the variance of political magazines 5.2. We cannot use this to make a valid comparison about the magazines to a magazine the content matters or maybe the number of readers matters not the number of word count.
Step-by-step explanation:
Given: The number of words per sentence in a sports magazine to the number of words per sentence in a political magazine. The data represent random samples of 10 sentences in each magazine.
Sports magazine [tex]$$9,21,15,14,25,26,9,19,22,30$$[/tex].
Political magazine [tex]$$31,22,17,5,23,15,10,20,20,17$$[/tex].
To compare the samples using measures of center and variation.
Find the mean of both the data and compare them.Find the variance of both the data and compare them.Step 1 of 2
The mean of the words of sports magazine is [tex]\begin{aligned}(9+21+15+14+25+&26+9+19+22+30) \times \frac{1}{10} \\&=\frac{190}{10} \\&=19\end{aligned}[/tex]
The mean of the words of the political magazine is [tex]\begin{aligned}&(31+22+17+5+23+15+10+20+20+17) \times \frac{1}{10}\\&=\frac{180}{10}\\&=18\end{aligned}[/tex]
On comparing the center i.e. mean we get that the sports magazine uses more words than a political magazine.
Step 2 of 2
Variation of sports magazine is [tex]=\frac{1}{10}\times(|19-9|+|19-21|+|19-15|+|19-14|+|19-25|+|19-26|+|19-9|+|19-19|+|19-22|+|19-30|)$$\\ $$=\frac{1}{10}\times(10+2+4+5+6+7+10+0+3+11)$$\\$$=\frac{1}{10}\times58$$\\$$=5.8$$[/tex]Variation of the political magazine is \end{tabular}

Answer:
its B
Step-by-step explanation:
because if you flip e to the other side of the y-axis you'll get (2,4) and do the same with the letters and that's your answer.
Answer:
B. C'(3 , 0) , D'(7 , 1) , E'(2 , 4)
Step-by-step explanation:
reflecting the point A(x , y) across the y-axis gives us the point A'(-x , y)
Then
The image of E(-2 , 4) is E'(2 , 4)
The image of C(-3 , 0) is C'(3 , 0)
The image of D(-7 , 1) is D'(7 , 1)
Therefore
The correct answer is option B.
