HELPPP FOR BRAINLEST!!! RIGHT NOW PLEASE

Answer:

9 and 3 are the second pair because 9×3=27 and9×9=81

Angle A = 100 (supplementary to the 80 angle)
Angle D = 100 (same reason)
Angle I = 130 (supplementary to the 50 angle)
Angle K = 100 (supplementary to angle H, and angle H = 80 since it is corresponding to the 80 angle)
Angle E = 80 (supplementary to angle A, and angle A = 100)

Note : Supplementary angles add up to 180, and corresponding angles are equal to each other. (with the condition of 2 lines are parallel to each other.)

Answer:

Angle A = 100

Angle D = 100

Angle I = 130

Angle K = 100

Angle E = 80

Step-by-step explanation:

Simplify x in the inequality.

Divide both -2x and 4 by -2:

[tex]\frac{-2x}{-2} < \frac{4}{-2}[/tex]

Answer:

[tex]x > -2[/tex]

The sign has switched since the terms have been divided by a negative number.

Answer:

Step-by-step explanation:

The solution is to isolate the term x from one side of the equation.

First, multiply by -1 from both sides.

(-2x)(-1)>(4)(-1)

Solve.

2x>-4

Then, divide by 2 from both sides.

2x/2>-4/2

Solve.

-4/2=-2

x>-2

Therefore, the correct answer is x>-2.

Answer:

879,200

Step-by-step explanation:

to get the answer we first must get the circumference of the wheel then we must multiply it by 10,000.  28 times 3.14(pie) is equal to 87.92. 87.92 times 10,000 is 879,200.

Note: I rounded pie.

Answer:

20 caramel apples are covered with sprinkles

Step-by-step explanation:

Let the fraction representing total number of apples = 120 = 1

We are told in the question:

1/5 of the caramel apple are covered with peanuts 1/3 are covered with chocolate chips 3/10 are covered with coconut The rest with sprinkles

Hence:

1 = 1/5 + 1/3 + 3/10 + Sprinkles

Sprinkles = 1 - (1/5 + 1/3 + 3/10)

LCM = 30

1 - (6 + 10 +9/30)

1 - 25/30

1 - 5/6

Fraction of caramel apples covered sprinkles = 1/6

The number caramel apples covered with sprinkles = 1/6 of 120 caramel apples

= 1/6 × 120

= 20 caramel apples are covered with sprinkles

Answer:  see proof below

Step-by-step explanation:

Use the Odd Function Identity: cos (-A) = - cos (A)

Proof LHS → RHS:

Answer:

160 m/s

Step-by-step explanation:

vi= 10m/s

a= 5om/s*2

t=3 second

vf=?

frist step: find s(distance)

s=vit+1/2 at*2=10m/s x3s +0.5 x50m/s*2 (3s)*2 =30m+225m=255m

second : find vf

s=(vf+vi)/2 xt

vf=2s/t- vi=2(255m)/3s -10 m/s=170 m/s-10m/s=160m/s

Therefore , the final velocity of the car is 160m/s

Answer:

y = 4x + 8

Step-by-step explanation:

A linear formula always follows by y = mx + c, where m is the gradient and c is the y-intercept or constant.

Since you know that the slope is 4, all you need to do is find the y-intercept (constant)

y = 4x + c

Sub in the points (-4, -8)

-8 = 4(-4) + c

-8 + 16 = c

c = 8

Hence, y = 4x + 8

if so point A coordinates are (-5:-8)

Let the zeros of a polynomial be α and β.

Here,

Therefore to find the equation of polynomial we have to do sum of zeros of the polynomial and the product of zeros of the polynomial.

Sum of the zeros of polynomial are :-

[tex] \sf \alpha + \beta = \frac{3}{2} + \frac{2}{5} \\ \\ : \rightarrow \: \frac{15 + 4}{10} = \frac{19}{10} [/tex]

Product of the zeros of polynomial are:-

[tex] \sf \: \alpha \beta = \frac{3}{2} \times \frac{2}{5} \\ \\ : \rightarrow \cancel\frac{6}{10} = \frac{3}{5} [/tex]

We know,

p(x) = x² - (α +β)x + αβ

putting values we get

p(x) = x² - 19/10x + 3/5

Hence, This is the required polynomial.

Answer:

x = 80°

Step-by-step explanation:

x + 36° + 76° + 74° + 94° = 360°

x + 280° = 360°

x = 360° - 280°

x = 80°

When a positive sign is considered then the value of x is -4 and when a negative sign is considered then the value of x is -14.

Simplification is to make something easier to do or understand and to make something less complicated.

The equatiuon is (x + 9)² = 25.

Take square root on both sides, then we have

(x + 9) = ±5

For positive signs, we have

x + 9 = 5

     x = -4

For negative signs, we have

x + 9 = -5

     x = -14

Answer:

x = 8

Step-by-step explanation:

11x - 34 and 7x - 2 are vertical angles and congruent, thus

11x - 34 = 7x - 2 ( subtract 7x from both sides )

4x - 34 = - 2 ( add 34 to both sides )

4x = 32 ( divide both sides by 4 )

x = 8

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

11x - 34 = 11(8) - 34 = 88 - 34 = 54

18y and 11x - 34 are adjacent angles and supplementary , thus

18y + 54 = 180 ( subtract 54 from both sides )

18y = 126 ( divide both sides by 18 )

y = 7

373.45 is the answer.

yes IF

20² = 11² + 18²

20² = 400

and

11² + 18² = 121 + 324 = 445

so NOT a right triangle
