Answer:

1) 5×5×5

2) False

3) False

Step-by-step explanation:

5 × 5 × 5

4² = 4×4 = 16

4² is 16, not 8

(-3)² = -3 × -3 = 9

-(3)² = -9

Answer:

86%

Step-by-step explanation:

1) divide 2750 by 3201 to get a part/whole ratio for a percent

2) divide and get 85.91%

Answer:

x = 85.9%

Step-by-step explanation:

Step 1:  Make an equation

[tex]3201 * x = 2750[/tex]

[tex]3201x = 2750[/tex]

Step 2:  Divide both sides by 3201

[tex]3201x / 3201 = 2750 / 3201[/tex]

[tex]x = 0.859...[/tex]

Step 3:  Convert to percentage

Answer:

Triangle QRS is an isosceles triangle because QR = RS.

Step-by-step explanation:

option D for Edgu hope this helps :)

The length of the given triangle: [tex]QR = 6.003, QS = 8.218, RS = 6.003[/tex].

The given triangle QRS is an isosceles triangle because [tex]QR = RS[/tex].

An isosceles triangle is a triangle that has two equal sides.

In the given triangle, the length of the sides are as follows:

[tex]QR = \sqrt{9 + 27.04} = \sqrt{36.04} = 6.003[/tex]

[tex]QS = \sqrt{64 + 3.53} = \sqrt{67.53} = 8.218[/tex]

[tex]RS = \sqrt{25 + 11.04} = \sqrt{36.04} = 6.003[/tex]

(Negative values are not taken)

In the given triangle,  [tex]QR = RS[/tex].

Therefore, the given triangle QRS is an isosceles triangle.

Answer:

1.  Distribute the 3

Step-by-step explanation:

3(6+x)=24

You can do one of two things

1.  Distribute the 3

3*6+3x=24

Or

you can divide each side by 3

The only reason it is a good choice to divide each side by 3 is that 24 is divisible by 3

3(6+x)/3=24/3

6+x = 8

Answer:

70

Step-by-step explanation:

There are 8 choices for the first member, 7 for the second, 6 for the third, and 5 choices for the fourth member (because once you pick someone as a member, they cannot be picked again)

So you have:

8*7*6*5 = 1680

However, we realize that in this particular problem, order DOES NOT matter. (for example, ABCD is the same as DCBA.)

So we divide 1680 by 4! (4*3*2*1) to end up with 70.

You do this because because there are 4! ways to arrange 4 people in a line, and since order doesn't matter, only one of those arrangements counts.

Final answer:

The volume of the cylinder is 1580.64 cubic inches.

Explanation:

To find the volume of a cylinder, we can use the formula V = πr²h, where V is the volume, r is the radius of the base, and h is the height.

In this case, the radius, r, is 6 inches and the height, h, is 14 inches.

So, the volume is calculated as follows:

V = π(6²)(14) = 3.14(36)(14) = 1580.64 cubic inches.

Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)²  + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Given

y = 2x² + 12x + 1

To express in vertex form use the method of completing the square.

The coefficient of the x² term must be 1 , thus factor out 2 from 2x² + 12x

y = 2(x² + 6x) + 1

add/ subtract ( half the coefficient of the x- term)² to x² + 6x

y = 2(x² + 2(3)x + 9 - 9) + 1

  = 2(x + 3)² - 18 + 1

  = 2(x + 3)² - 17 → C

Answer:

answer : C    2(x-3)²-17

Step-by-step explanation:

hello :

answer : C    2(x-3)²-17

calculate :   2(x-3)²-17 = 2(x²-6x+9)-17 = 2x²-12x+18-17

                  2(x-3)²-17 = 2x²-12x+1.....(right)

Answer:

25.12

Step-by-step explanation:

Answer:

104

Step-by-step explanation:

First, put the word equation into a numerical equation.

-4+5x=7x-212                            This is our equation

-4=2x-212                                  I subtracted 5x from both sides

208=2x                                     I added 212 to both sides

104=x                                         I divided both sides by 2

To solve the problem, we can set up an equation and solve for the variable 'x'. The number is x = -25.

To solve this problem, we can translate the given information into an equation. Let's assume the number is 'x'. The sum of -4 and 5 times 'x' is -4 + 5x. The equation becomes 3(-4 + 5x) = 7x - 212. We can simplify this equation and solve for 'x' to find the number.

First, distribute the 3 to -4 and 5x, which gives us -12 + 15x = 7x - 212. Then, combine like terms by subtracting 7x from both sides, which gives us -12 + 8x = -212. Next, add 12 to both sides to isolate the variable, resulting in 8x = -200. Finally, divide both sides by 8 to solve for 'x'. The number is x = -25.

Answer:

Acute

Step-by-step explanation:

The peak of the house forms acute angled triangle.

Answer:

13,14,15

Step-by-step explanation:

Let x be the first number

x+1 is the second number

x+2 = third number

x+ x+1 +x+2 = 42

Combine like terms

3x+3 =42

Subtract 3 from each side

3x+3-3 = 42-3

3x = 39

Divide each side by 3

3x/3 = 39/3

x = 13

The numbers are 13

13+1 =14

13+2 = 15

Answer:

13,14,15

Step-by-step explanation:

What three consecutive integers have a sum of 42? Which means that the first number is 13, the second number is 13 + 1 and the third number is 13 + 2. Therefore, three consecutive integers that add up to 42 are 13, 14, and 15.

Step-by-step explanation:

Trust me, I kept googling this for almost an hour.

The Average of the Dinner is 20.66.

In mathematics, the middle value—which is determined by dividing the sum of all the values by the total number of values—is the average value in a set of numbers. To calculate the average of a set of data, add up all the values and divide the result by the total number of values.

The data for dinner is:

18.8, 22.13, 20.79, 24.82, 16.74

The Average of the Dinner is

= ( sum of all data for dinner)/ Total Number of Dinner

As, sum of all data for dinner = (18.8 + 22.13 + 20.79 + 24.82 + 16.74)

                                                =103.28

and, Total Number of Dinner = 5

Now put the values we get

= (18.8 + 22.13 + 20.79 + 24.82 + 16.74) / 5

= 103.28/ 5

= 20.656

= 20.66

Thus, the average of the dinner is 20.66

10x=56

X=56/10

X=5.6

The value of X= 5.6

Answer:

x = 5.6

Step-by-step explanation:

Expressing the ratio in fractional form, that is

Answer:

1/3

Step-by-step explanation:

there are 2 numbers greater than 4 on dice and there are 6 numbers on a die

Answer:

C

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (8, - 14), thus

y = a(x - 8)² - 14

To find a substitute (5, 13) into the equation

13 = a(5 - 8)² - 14

13 = a(- 3)² - 14

13 = 9a - 14 ( add 14 to both sides )

27 = 9a ( divide both sides by 9 )

a = 3

Thus

y = 3(x - 8)² - 14 → C
