The formula is this tho:

V=πr^2h

Answer:

C

Step-by-step explanation:

Answer:

6(x + 9) (x + 9)

or

[tex]6 (x+9)^{2}[/tex]

Step-by-step explanation:

[tex]468 + 108x + 6x^{2} \\6x^{2} +108x + 468[/tex]

Greatest common factor of 6, 108, and 486:

6 x 1 = 6

6 x 18 = 108

6 x 81 = 486

GCF: 6

so:

[tex]6(x^{2} +18x +81)[/tex]

[tex]x^{2} +18x + 81[/tex]

factors to:

(x + 9) (x + 9)

because:

9 x 9 = 81

9 + 9 = 18

So:

It factors completely too:

6(x + 9) (x + 9)

or

[tex]6 (x+9)^{2}[/tex]

Answer:

2g-2

.....................

Answer

2g -2

Step-by-step explanation:

Answer:

1. x = 4

2. x = -2/3

3. x = -5

1. f(x) = 5x + 3

2. f(x) = 4/5x

3. f(x) = (2x + 7)/4

4. f(x) = (2x + 7) /(x + 3) = 2 + 1/(x + 3)

5. f(x) = [tex]\sqrt{x - 4}[/tex]

Answer:

Area = 1.54

Step-by-step explanation:

Area = π[tex]r^{2}[/tex]

π = 3.14

diameter = 1.4

radius (half of diameter) = 0.7

Area = 3.14 x [tex]0.7^{2}[/tex]

Area = 3.14 x 0.49

Area = 1.5386

round to the nearest hundredth:

1.5386 = 1.54

Answer:

x=amount invested at 7%

2x=amount invested at 8%

3x=amount invested at 9%

interest=principal*rate*time (time=1 year)

$150=0.07x+0.08*2x+0.09*3x

$150=0.07x+0.16x+0.27x

$150=0.50x

$1500=5x

x=$300 invested at 7%

2x=$600 invested at 8%

3x=$900 invested at 9%

Step-by-step explanation:

Answer: I am taking the test rn and I think its (C) Since the trend line is a positive correlation and slope, so then a good estimate would be 6

Step-by-step explanation: I may be wrong, but this is the best choice in my opinion

Answer:

Step-by-step explanation:

If a quadrilateral is a parallelogram, then its opposite sides are congruent. If a quadrilateral is a parallelogram, then its opposite angles are congruent. If a quadrilateral is a parallelogram, then its diagonals bisect each other.

Answer:B-70

Step-by-step explanation:

from the figure, In [tex]\triangle ABC\ \text{and}\ \triangle ADE[/tex]

[tex]\Rightarrow \dfrac{45}{45}=\dfrac{24}{24}\\\Rightarrow \dfrac{1}{1}=\dfrac{1}{1}[/tex]

[tex]\therefore \text{two triangles are similar}[/tex]

Thus we can write

[tex]\Rightarrow \dfrac{35}{x}=\dfrac{45}{45+45}\\\\\Rightarrow x=35\times \dfrac{90}{45}=35\times 2=70[/tex]

Replace w and z with the given values:

5^2 + 2 + 48 / 2(8)

Simplify:

75/16 = 4 and 11/16

Answer:

With no digits repeated that would be 60,480

Step-by-step explanation:

9×8×7×6×5×4 = 60,480

Answer:

Mystery Number is 8

Step-by-step explanation:

3x - 15 = 5 + 1/2x

3x - 1/2x = 15 + 5

5/2x = 20

x = 20 / 5/2

x = 20 * 2/5

x = 40 / 5

x = 8

Answer: yes they are

Step-by-step explanation:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal.

Answer:

Yes

Step-by-step explanation:

While congruent triangles are similar, similar triangles may not be congruent.

Answer:

5

Step-by-step explanation:

area of a square= side x side

Answer:

3/8

Step-by-step explanation:

After spending 3/8 of her money on a bag, she has 5/8 of the original amount of money left. As she gave 2/5 of the remaining amount of money to her sister, she gave 1/4 of the original amount of money to her sister (5/8 × 2/5 = 1/4). Therefore, there's only 3/8 (1 - 3/8 - 1/4 = 3/8) of the original amount of money left in her bag.

Answer: 9$

Explanation:

5 + 3 + 1 + x + 2 = 20

Subtract all those numbers

x = 9

5 + 3 + 1 + 9 + 2 = 20

20 / 5 = 4

No, it is not a right triangle. It is an obtuse triangle.

Step-by-step explanation:

How to know a right traingle

A right triangle is a triangle in which one of the angles is a 90∘ angle. The "square" at the vertex of the angle indicates that it is 90 degrees. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.

i dont know im just doing this for the points

Answer: {2,4}

Step-by-step explanation: Khan Academy

Given:

The inequality is:

[tex]x>3[/tex]

To find:

The negation of the given inequality.

Solution:

The given inequality is [tex]x>3[/tex], it means all the value which are greater than 3 are included in the solution set.

Since all the values which are less than or equal 3 are not included in the solution set, therefore the negation of the given inequality is

[tex]x\leq 3[/tex]

Therefore, the negation of [tex]x>3[/tex] is [tex]x\leq 3[/tex].

Step-by-step explanation:

Answer:

c. x= 28°, y= 76°

Step-by-step explanation:

y= 180-104=76°

104= x+y (property of triangle, exterior angles is equal to the sum of opposite interior angles)

x=104-76= 28°

Answer:

Step-by-step explanation: Just do 0.25+0.25 then the answer x 0.18 and then divide the answer by 2 and it should equal 0.045
