Mathematics

SpyIntel [72]3 years ago

Answer:

3+7 = 3

Step-by-step explanation:

Given question is based on reasoning:

2+3=1

2+3 = 5 and 5 × (2) first digit = 10, digit place reverse = 01

Similarly

4+5=63

4+5 = 9 and 9 × (4) first digit = 36, digit place reverse = 63

6+8=48

6+8 = 14 and 14 × (6) first digit = 84, digit place reverse = 48

So,

3+7=

3+7 = 10 and 10 × (3) first digit = 30, digit place reverse = 03

Therefore, 3+7 = 3

a box half full of apples weighs 40kg and the same box one fifth full weighs 22kg. what does the box weigh when empty?
likoan [24]
So in order to answer your question  we calculate 40 - 22 wich gives us the answer of 18, so now we can say that 4/5 of apples weight 18 so now 18 / 4 = 4,5; 4,5 * 5 = 22,5 wich is the weight of apples you can put in the box, to know the answer we deduct the greatest weight of apples only from the weight of the box with those apples so, 40 - 22,5 = 17,5
so the answer to your question is 17,5

Angle ACB is an inscribed angle of circle P. What is the measure of angle ACB if arc MAB is equal to 50 degrees?
Yakvenalex [24]

∠ACB is an inscribed angle, so

<h3>Answer:  161 degrees</h3>

=========================================================

Explanation:

Line AE is a tangent while line AU is a secant. The angle formed by the secant and tangent lines connects with the arcs through this formula

secant tangent angle = (larger arc - smaller arc)/2

More specifically, we can say:

angle EAI = (arc EU - arc IE)/2

42 = ( (7m+5) - (3m-1) )/2

42*2 = (7m+5) - (3m-1)

84 = 7m+5 - 3m+1

84 = 4m+6

4m+6 = 84

4m = 84-6

4m = 78

m = 78/4

m = 39/2

m = 19.5

Use this value of m to compute each arc

  • arc IE = 3m-1 = 3*19.5-1 = 57.5 degrees
  • arc EU = 7m+5 = 7*19.5+5 = 141.5 degrees

Let's say arc IU is some unknown number x. It must add to the other two arc measures to form 360 degrees, which is a full circle.

(arc IU) + (arc IE) + (arc EU) = 360

x + 57.5 + 141.5 = 360

x + 199 = 360

x = 360-199

x = 161

The measure of minor arc IU is 161 degrees

After solving the system x+2y=10 and x-2y=2. What is the sum of x+y equal to?
Masja [62]

Answer:

The sum of x and y is 8.

Step-by-step explanation:

x+2y=10

x-2y=2

------------

2x = 12, so x = 6.  Substituting 6 for x in the 2nd equation, we get:

6 - 2y = 2, or

4 = 2y, or y = 2.  The solution is therefore (6, 2).

The sum of x and y is 6 + 2 = 8 (answer)
