Sorry about the last time this time I could find the images!

First problem: 120

Second problem: I believe its 140 but I dont know for sure so answer that at your own risk please

Third problem: same for this one I think it's 40

Fourth problem: 2160

Answer: I would say that it is 7

Step-by-step explanation:

30 : 24

b : 4       (divide both sides by 6)

5 : 4

Equivalent to 5 would be 7

Sorry if its wrong

The diameter can be thought of as the width of the circle, more or less. More accurately, it's the distance from one point on a circle, through the center, to a point on the opposite side.

If we had a circle at point A, and some point on the edge of the circle point B, then line AB will form a third point C. Point C is on line AB and on the circle. Segment BC is a diameter.

We can measure the diameter with a straight line ruler, but we cannot do the same with the perimeter of the circle. The circumference is just a fancy name for "perimeter". Specifically, it only applies to circles. The way I remember it is that "circle" has "circ" in it, and so does "circumference". Furthermore, we can erase some letters of "circumference" to end up with "fence", which would go along an outer perimeter in a lot of cases. Overall, "circumference" makes me think of "circle fence".

How can we find the perimeter of a circle? Well we could use a cloth ruler to wrap around the edge of the circle. We'd have to make sure that none of the bendable ruler is out of place. So things could get tricky.

To find the circumference with a formula, we'll use this one here

C = pi*d

where pi = 3.14 approximately and d is the diameter

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

For example, let's say the diameter is d = 10 feet. That would lead to a circle perimeter of....

C = pi*d

C = 3.14*10

C = 31.4

The circumference is approximate because pi = 3.14 is approximate. The units for the circumference in this case are in feet, so the distance around this particular circle is about 31.4 feet.

Answer:

  both of them: x = -4, x = -735

Step-by-step explanation:

The meaning of "real root" is that the graph intersects the x-axis at that value of x. If the degree of the root is odd, the graph crosses there. (If the degree of the root is even, the graph only touches the x-axis.)

  f(x) = (x +4)(x +735)

has real roots at x = -4 and x = -735, so crosses the x-axis in those places.

Yup, 11 is the answer. because 4 -15 is 11.

Answer:

a) x(x+1)

b) 3x(1-3)

c) 7x(1-5)

d) 4x²(x+6)

Step-by-step explanation:

When factorising, the most important thing to do is find what the terms have in common. Divide each term by what they have in common, then multiply it by the entire expression so the value doesn't change. Also, you can always check your answer by multiplying it out to see if you get what you started with.

a)

x² + x, both terms have 'x' in common:

x( (x²/x) + (x/x) ) = x(x+1)

b)

3x - 9x, both terms have '3x' in common:

3x( (3x/3x) - (9x/3x) ) = 3x(1-3)

c)

7x - 35x, both terms have '7x' in common:

7x( (7x/7x) - (35x/7x) ) = 7x(1-5)

d)

4x³+ 24x², both terms have 4x² in common:

4x²( (4x³/4x²) + (24x²/4x²) ) = 4x²(x+6)

Answer:

703

Step-by-step explanation:

You divide the 8436 by 12.

1. You can't divide the 8 by 12 so skip that

2. You can divide 84 by 12 so you get 7

3. Bring down the 3 (you have 0 as a remainder). You can't divide that so put a 0

4. Bring down the 6 and divide that (36) and you get 3

5. Your final answer would be 703.

Answer:

(-9.15)

Step-by-step explanation:

We are given these following vectors:

u = (2,4), v = (-1,-1), w = (7,-2)

What is the vector for 3u + v- 2w in component form?

3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)

The answer is (-9,15).

Answer:

5. 4186.67 in³

6. 1436.03 ft³

7. 3052.08 cm³

Step-by-step explanation:

5. Determination of the volume of the sphere.

Radius (r) = 10 in

Pi (π) = 3.14

Volume (V) =?

V = 4/3πr³

V = 4/3 × 3.14 × 10³

V = 4/3 × 3.14 × 1000

V = 4186.67 in³

6. Determination of the volume of the sphere.

Radius (r) = 7 ft

Pi (π) = 3.14

Volume (V) =?

V = 4/3πr³

V = 4/3 × 3.14 × 7³

V = 4/3 × 3.14 × 343

V = 1436.03 ft³

7. Determination of the volume of the sphere.

We'll begin by calculating the radius. This can be obtained as follow:

Diameter (d) = 18 cm

Radius (r) =?

r = d/2

r = 18/2

r = 9 cm

Finally, we shall determine the volume of the sphere. This can be obtained as follow:

Radius (r) = 9 cm

Pi (π) = 3.14

Volume (V) =?

V = 4/3πr³

V = 4/3 × 3.14 × 9³

V = 4/3 × 3.14 × 729

V = 3052.08 cm³

Answer:

s = 1.81

Step-by-step explanation:

4.4(1.81)+6.2=8.8(1.81)-1.8

plug in and multiply if you'd like to clarify :)

Answer:

=Steps

4.4s+6.2=8.8s−1.8

Multiply both sides by 10

4.4s· 10+6.2· 10=8.8s· 10−1.8· 10

Refine

44s+62=88s−18

Subtract 62 from both sides

44s+62−62=88s−18−62

Simplify

44s=88s−80

Subtract 88s from both sides

44s−88s=88s−80−88s

Simplify

−44s=−80

Divide both sides by −44

−44s

−44 =

Answer:

25 in.

Step-by-step explanation:

DEC is a right triangle. <DEC is a right angle.

(DE)² + (EC)² = (DC)²

DE = ½DB = ½(48 in.) = 24 in.

(24 in.)² + (7 in.)² = (DC)²

576 in.² + 49 in.² = (DC)²

(DC)² = 625 in.²

DC = 25 in.

Step-by-step explanation:

2x - 5 = y - 5

2x = y

x = y/2

y - 3 = x + 1

Substitute the value of x here,

y - 3 = [tex]\rm{\dfrac{y}{2} + 1}[/tex]

y - 3 = [tex]\rm{\dfrac{y + 2}{2}}[/tex]

2y - 6 = y + 2

y = 8

Now, x = 8/2

x = 4

So, go for D part, it is the correct answer.

Good Night/Day !

Answer:

x = 4, y = 8

Step-by-step explanation:

For the triangles to be congruent by the HL theorem

Then the hypotenuse and legs must be congruent , that is

x + 1 = y - 3 → (1)

2x - 5 = y - 5 → (2)

Subtract (1) from (2) term by term to eliminate y

2x - x + (- 5) - 1 = y - y + (- 5) - (- 3) , that is

x - 6 = - 2 ( add 6 to both sides )

x = 4

Substitute x = 4 into either of the 2 equations and solve for y

Substituting into (1)

4 + 1 = y - 3

5 = y - 3 ( add 3 to both sides )

8 = y
