Can someone help me with 5, 8 and 9?

Answer: 8 45 degree angles

Step-by-step explanation:

A circle is 360 degress. 360 divided by 45 equals 8

Answer:

8

Step-by-step explanation:

a circle is 360°. to find how many 45° angles it would take to turn in a complete circle:

360°/45°=8

it would take 8 45° angles to turn in a complete circle

Answer:

-2

Step-by-step explanation:

You can see that when x goes up by 1, y goes down by 2. This means the rate of change is -2

Answer:

The rate of change is -2

Step-by-step explanation:

Take any two points from the graph. (0,-4) and (-2,0). Plug them into the equation y2-y1/x2-x1. In this case the equation would be 0--4/-2-0. Simplify this and get 0+4/-2-0. Simplify again and get 4/-2 which is -2

Therefore the rate of change is -2

Answer:

Isosceles Triangle

Step-by-step explanation:

Triangle ABC has vertices A(-5, -1), B(5, -1), and C(0, -4). Is it scalene, isosceles or equilateral?

We solve this question using vertices formula:

√(x2 - x1)² + (y2 - y1)² when given vertices: (x1, y1) and (x2 , y2)

For Side AB

A(-5, -1), B(5, -1)

AB = √(5 - (-5))² + (-1 -(-1))²

AB= √(5 + 5)² + (-1 + 1)²

AB = √10² + 0

AB = √100

AB = 10 units

For Side BC

B(5, -1), C(0, -4)

BC = √(0 - 5)² + (-4 -(-1))²

BC = √-5² + (-4 + 1)²

BC = √25 + -3²

BC = √25 + 9

BC = √34

For Side AC

A(-5, -1), C(0, -4).

AC = √(0 - (-5))² + (-4 - (- 1)²

AC = √5² + -3²

AC = √25 + 9

AC = √34

Therefore this triangle is an isosceles triangle because 2 of its sides (AC and BC ) are equal to one another

Answer:

25 divided by 1/4

Answer:

15 1/6

Step-by-step explanation:

change -8 2/3 into an improper fraction = -26/3

-4/7v = -26/3

cross-multiply:

3(-4v) = (-26)7

-12v = -182

v = 182/12

v = 15 1/6

Answer:

The internal rate of change over the interval (-1,2) is 1

Answer:

Answer:

complementary

x = 15

Step-by-step explanation:

The outer angle is a right angle as denoted by the red square mark. A right angle has a measure of 90°.

Complementary angles are angles whose measures have a sum of 90°.

Angles 3x and 45 are complementary angles.

3x + 45 = 90

3x = 45

x = 15

Answer:

complementary

x = 15

Answer:

her hourly pay is £8.50

Step-by-step explanation:

h= hourly pay

n = number of hours worked over 40 hours in a week

week pay = 40h + (n x 2 x h)

544 = 40h + 2nh

52 - 40 = 12, so n = 12

544 = 40h + 2 x 12 x h

544 = 40h + 24h

544 = 64h

544/64 = 8.5 h=8.5 (£8.50)

just to check:

£8.50 x 40 = £340

£8.50 x 2 x 12 = 204

340 + 204 = 544 yayy the answer is correct

hope this helps x

Answer:

n = 2

Step-by-step explanation:

Given nx + y = 4, if we rearrange in slope-intercept form: y = -nx + 4

This means that the y-intercept is 4. Point "A" is the y-intercept, which would make OA = 4, and OB = 1/2(4) = 2.

We can now solve for n. The slope here is "-n", also represented by rise/run or OA/-OB = 4/-2 = -2.

-n = -2,

n = 2

Answer:

Step-by-step explanation:

<Q is common to both triangles.

130 / 40 = 3.25

Call DQ = x

40/130 = x / (x + 72)       Cross multiply

40*(x + 72) = 130*x

40x + 2880 = 130x      Subtract 40 x from both sides

2880 = 90 x                 Divide by 90

x = 32

(72 + 32)/32 = 104/32 = 3,25

The ratios are the same.

Therefore the triangles are similar by SAS

Answer: 314 mm

Step-by-step explanation:

Area of a circle is π*r^2

r is radius and π is 3.14

here the radius is 10

3.14 * 10^2 = 3.14 * 100 = 314

Answer:

the answer is 15x+3=3(5x+1)

Answer:

n = 50

Step-by-step explanation:

Let a be the first term and d be the common difference.

An arithmetic sequence has a 2nd term equal to 3 and 10th term equal to -13.

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

According to the given condition,

[tex]a_2=3\\\\a_{10}=-13[/tex]

or

[tex]a+(2-1)d=3\\\\a+d=3\ ...(1)\\\\a+(10-1)d=-13\\\\a+9d=-13\ ...(2)[/tex]

Subtract equation (1) from (2).

a+9d-(a+d) = -13-3

8d = -16

d = -2

Put the value of d in equation (1).

a+(-2) = 3

a = 3+2

a = 5

Now,

[tex]a+(n-1)d = -93\\\\5+(n-1)(-2)=-93\\\\5-2n+2=-93\\\\7+93=2n\\\\2n=100\\\\n=50[/tex]

So, 50th term has the value of -93.

-53
