Answers

Answer:

Step-by-step explanation:

As these are alternate angles hence we got that ,

both angles will be equal ,

7x+5 = 47

x= (47-5)/7

x=6 degree

Answer:

x = 6°

Step-by-step explanation:

7x + 5° = 47°, because of alternate exterior angles (We can use this because the lines are parallel). Since we know this, we can solve for x.

Solving this equation:

7x + 5 = 47 and if you subtract by 5 on both sides you would get that 7x = 42. From here, you divide 42 by 7 to get your answer. 42/7 = 6 so x = 6 degrees.

Note: I assumed that the angle 7x + 5 was 7x + 5°

What is the 21st term of the sequence with a1 = -7 and d = 3?
A . -4
B . -11
C . -21
D . 53

Answers

Answer:

[tex]T_{21} = 53[/tex]

Step-by-step explanation:

Given

[tex]a = -7[/tex]

[tex]d = 3[/tex]

Required

Determine [tex]T_{21}[/tex]

This is calculated using sum of Ap formula

[tex]T_n = a + (n - 1)d[/tex]

In this case:

[tex]n =21[/tex]

So, the equation becomes

[tex]T_{21} = -7 + (21 - 1) * 3[/tex]

[tex]T_{21} = -7 + 20 * 3[/tex]

[tex]T_{21} = -7 + 60[/tex]

[tex]T_{21} = 53[/tex]

80 points! Look at the pic attached. I will mark brainliest to the correct answer. Random answers will be reported :) thanks

Answers

Answer: No, it is not commutative. If used a square as an example, centered at (1,1). If a dilation is performed on the square of a scale factor of 3, and the square is translated 5 units downward, then the result would be different than if I switched the order, doing the translation downward first and then performing the dilation centered at (1,1).

In a class room 3/10 of the students are wearing blue shirts and 3/5 are wearing white shirts there are 20 students In The classroom how many students are wearing shirts other than white or blue shirts

Answers

Total number of students in the class = 36

Number of students wearing blue shirts = (1/6) * 36

= 36/6

= 6

Number of students wearing white shirts = (2/3) * 36

= 2 * 12

= 24

Then

Number of students not wearing blue or white shirts in the class = 36 - (6 + 24)

= 36 - 30

= 6

So 6 students in the class are wearing a shirt other than a blue or a white shirt. I hope the procedure is clear enough for you to understand.
