1 median=60.3

2 missing number=38

Step-by-step explanation:

1 45+55+76+y+88+54/6

316+y/6=63.6

316+x381.6

x=381.6-316=65.6

2M4 =63

60-62+92+x/4=63

214+x=252

x=252-214

=38

gladu [14]

Answer:

Step 1: Enter the number in the respective input field

Step 2: Now click the button “Solve” to get the answer

Step 3: Finally, the significant figures of the number will be displayed in the output field

What is Meant by Significant Figures?

In Mathematics, the significant figures define the number of important single digits that contribute to the degree of accuracy of the given number. The five important rules for the significant figures are as follows:

All the non zero numbers are significant figures

The zero present in between the non zero numbers are significant figures

The leading zeros are not significant

The trailing zeros present at the right side of the decimal point are significant figures

Trailing zeros of the number without a decimal point are not significant figures

The trailing zeros present in the whole number with the decimal point are significant figures

13 pages : 1/2 hour Multiply both sides by 2

26 pages : 1 hour ------>> 26 pages/hr

Flip over 26 pages/hr ----->>> hr / 26 pages = 1 hr / 26 pages

Split up the fraction: (1/26) hr / page

Hey guys I need help plz asap
Ilya [14]
Answer:

Explanation:

AB = BC
=> Triangle ABC is an Isosceles Triangle
Thus, Angle C = Angle A
DE = BE
=> Triangle DEB is an Isosceles Triangle
Thus, Angle D = Angle B

Proof that triangle ABC and DEB are similar:

Angle DBE = Angle A (corresponding angle)
Angle BDE = Angle C (Both Triangle are Isosceles, if one pair of the angle are equal then the other pair should also be equal)

=> Triangle ABC ~ Triangle DEB (AA)

Therefore, Angle E = Angle B

Find angle B:

Angle C + Angle A + Angle B = 180
40 + 40 + angle B = 180
Angle B = 180 - 80
Angle B = 100 degree

But Angle B = Angle E = 100 degree

Therefore, Angle E = 100 degree

Write an expression for “the quotient for y and 8”
jonny [76]

Answer:


Step-by-step explanation:

I think your answer is y/8. It's a little unusually worded. If this is not correct, please leave a note.

The way I have answered it, I would word it as "What is the quotient of y divided by 8."
