Answer:

137 degrees

Step-by-step explanation:

in the triangle with 60 degrees : the top angle must be also 45 degrees (the same as the angle above it).

then its third angle must be 180 - 60 - 45 = 75 degrees (because the sum of all angles is always 180 degrees in any triangle).

then the sum of this 75 degrees angle, then the neighboring 68 degree angle and the next one (the left angle in the triangle with 100 degrees) together must be again 180 degrees, because all angles around a point on one side of a line are 180 degrees (a half circle).

that means this left angle of the 100 degrees triangle is

180 - 75 - 68 = 37 degrees.

that means that the right angle of the 100 degrees triangle is

180 - 37 - 100 = 43 degrees (again, because of the sum in a triangle).

and now that gives us the ? angle as

180 - 43 = 137 degrees

because this is again the sum around s point on a line (the line is the arrow line starting at the 100 degrees angle pointing leading and pointing to the bottom right).

Answer:

Step-by-step explanation:

4 - 0.4 = 3.6

3.6 - 0.4 = 3.2

2.8 - 0.4 = 2.4

2.4 - 0.4 = 2

2 - 0.4 = 1.6

so the next numbers in the pattern are: 2.4, 2 and 1.6

Answer:

x=-1/25

Step-by-step explanation:

-3/5x=15

-3/5x(5x)=15(5x)

-3=75x

75x=-3

x=-3÷75

=-3/75

=-1/25

Answer:

(2,-3), (3,-1), (4,-4), (6,-1)

Answer:

You will need to count the amount of 0's and total them left to right = per question and total them top to bottom for answering a total

answering b total answering c total etc..

This creates line of 5 totals at the bottom of table and other totals per question = amount of questions x total.

The experimental probability is setting all 1/5 (1 answered question and multiplying it by the inverse of 4/5 non answered questions =  1/5  = 1/25

p) 1/5 x 1/5 = 1/25

Answer:

11-2i

Step-by-step explanation:

Distribute the negative

5-5i+6-3i

Combine like terms

11-2i

Hope this helped!!

Have a nice day!

Answer:

[tex]\boxed{\sf 11-2i}[/tex]

Step-by-step explanation:

[tex]\sf (5-5i)-(-6-3i)[/tex]

Opposite of -6 - 3i is 6+3i:

[tex]\sf 5-5i+(6+3i)[/tex]

Combine real and imaginary numbers 5-5i and 6+3i:

[tex]\sf 5+6+(-5+3)i[/tex]

Add 5 to 6, and -5 to 3:

[tex]\sf 11-2i[/tex]

Answer:

- 3, - 2, - 1 and 6

Step-by-step explanation:

To find the first 3 terms, substitute n = 1, 2, 3 into the nth term rule

a₁ = 1 - 4 = - 3

a₂ = 2 - 4 = - 2

a₃ = 3 - 4 = - 1

The first 3 terms are - 3, - 2, - 1

similarly substitute n = 10 into the rule for 10th term

a₁₀ = 10 - 4 = 6

Answer: d

Step-by-step explanation:

because after you multiply x 3 times you can use the 3 would be the square root of the number you got and a complex root you can't do that

For example: 9 x 3 = 27  the square root of 27 is 5.2 and that's is rounded

Answer:

[tex]11[/tex]

Step-by-step explanation:

[tex]an = 3n - 4[/tex]

To solve this put 5 Instead of n

[tex]a5 = 3 \times 5 - 4 \\ = 15 - 4 \\ = 11[/tex]

Hope this helps you.

Step-by-step explanation:

B is the answer y2=-12x

if that helps

Answer:

i) no. of students like none of subject = 5

total no. of students= 69

=> no. of students like at least one subject= 60-5

= 55

ii) no. of students like math only = 15

no. of students like science only = 20

total no. of students like only one subject= 35

no. of students like none subject = 5

=> no of students like both the subjects = 60-(35+5) =20

(iii) no. of students like math= 15+ 20

= 35 ( because 15 like math only and 20 like both)

(iv) no. of students like science= 20+20

= 40 ( because 20 like science only and 20 like both )

Step-by-step explanation:

Answer:

35 kids.

Step-by-step explanation:

55 kids who like math or science

15 math only and 20 science only

s0 20 who like both math and science
