Answer 1

Answer:

180° (in place of blank)

Step-by-step explanation:

GIVEN :-

∠D = 127°∠A = 75°

PROCEDURE :-

∠C & ∠D are linear pair. (∵ They lie on same line)

⇒ ∠C + ∠D = 180°

⇒ ∠C = 180° - 127°

In a triangle , sum of its all interior angles equals to 180° (which is also known as "Angle Sum Property). So,

∠A + ∠B + ∠C = 180°

⇒ 75° + ∠B + (180° - 127°) = 180°

⇒ ∠B = 180° - 75° - (180° - 127°)

The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?

Answers

Answer:

One number is 4.2, the other is 18.8

Step-by-step explanation:

1.)  x+y=23

    (x+6y)x2=4

2.) (x+6y)x2=4   =   2x+12y=4

3.)Use elimination/substitution to solve

     2x+12y=4  =   x+6y=2  =  x=2-6y

     2-6y+y=23

4.)Solve for y

     2-5y=23 -> -5y=21 -> y=4.2.

5.)Solve for x

    x+4.2=23

    x=18.8

Answers

Answer:

x=6

Step-by-step explanation:

I would look at this triangle and notice that x can be solved by setting up a ratio.

I generally put the short side of the triangle on the top and the long side on the bottom

4/x = x/9

You then cross multiply to get 36=x^2, or +-6=x

A length of a triangle cannot be negative, so we are left with the answer x=6

At Kirby Middle School, some students were surveyed to see which social
media app they used the most. The results are shown below.
App Number of Students
Face
8
Snap
22
Insta
20
Solve and explain how to calculate what percent of students used Snap the
most?

Answers

Answer:

Kirby Middle School

The percentage of students who used Snap the most is given as:

= 44%

Step-by-step explanation:

a) Data and Calculations:

App   Number of Students

Face          8

Snap        22

Insta        20

Total      50

The percentage of Snap users = Number of Snap users/Total users * 100

= 22/50 * 100 = 44%

b) This represents the proportion of all the students surveyed about the use of social media app.  Since 22 students used Snap out of 50, it means that 44% of the survey sample used Snap.  This is against 16% (8/50) who used Face and 40% (20/50) who used Insta.
