Answer:

166

Step-by-step explanation:

A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.

A=2(wl+hl+hw)=2·(7·5+4·5+4·7)=166

A = 166

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.

Then factor 9x² + 30x + 25 as

(3x + 5)²

Answer:

A.

Step-by-step explanation:

1 foot = 12 inches.

Convert the dimensions of the region to inches:

2 feet = 24 inches

5 feet = 60 inches

Area of region = 24 x 60 = 1,440 sq. In.

Area of tile = 3 x 4 = 12 sq. In.

Number of tiles needed = 1440/12 = 120

120 tiles are needed.

13/5

13 does not go into 5 so put a decimal point after the 5

13/5.000 carry the 5 over to the zero

13 goes into 50 3 times with 11 left over. carry the 11 over to the next zero. 13 goes into 110 8 times with 6 left over. carry over to the next zero. keep adding zeros and carrying over until the 13 goes into a number equally.

the answer is 0.38461538

Answer:

60

Step-by-step explanation:

Angles 1 and 2 are supplementary, which means that their sum is 180 degrees.

180 - 120 = 60

Angle 1 is 60 degrees

If Z2 measures 120°. We can see that Angles 1 and Angles 2 are supplementary. Therefore, Angle 1 is 60 degrees.

Two angles whose sum is 180° are called supplementary angles.

If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line.

Those two-two angles are two pairs of supplementary angles.

That means, if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.

If Z2 measures 120°

We can see that Angles 1 and Angles 2 are supplementary, which means that their sum is 180 degrees.

Angles 1 + Angles 2 = 180

Angles 1= 180 - 120

Angles 1 = 60

Therefore, Angle 1 is 60 degrees.

Answer:

2x(5x + 14) + 15

Step-by-step explanation:

Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)

                              = (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x

                              = 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x

collecting like terms to have,

8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15

10[tex]x^{2}[/tex] + 28x + 15

Thus,

(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15

                                           = 2x(5x + 14) + 15

Answer:

The missing value is 6!

Step-by-Step Explanation:

First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)

Now, we can write this as a function, where we can represent the missing value as 'x'.

[tex]4+5+13+x=28[/tex]

In order to get the missing value, we must solve the equation.

Step 1: Simplify.

[tex]4+5+13+x=28\\22+x=28[/tex]

Step 2: Subtract 22 from both sides.

[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]

x is equal to 6, which means the missing volume of gas is 6!

Step-by-step explanation:

just multiply 63.5 by 2.54

The centimeter equivalent of Sadie's height is  142.875 cm.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Sadie is 63.5 inches tall and 2.54 cm equals 1 inch.

∴ Sadie's height in cm will be his height in inches multiplied by 1 inch equivalent of cm which is,

= (63.5×2.25) cm.

= 142.875 cm.

Answer:

6 cm

Step-by-step explanation:

Given that:

A line that contains the points R, S and T.

Distance between R and S = [tex]2x[/tex]

Distance between S and T = [tex]3x[/tex]

To find:

The distance between S and T = ?

Solution:

The given situation and dimensions can be represented in the form of a diagram as shown in the attached diagram.

As per given statement and in the diagram, we can deduce that the sum of distance between R and S, S and T is equal to distance between R and T.

i.e. RS + ST = RT

[tex]2x + 3x = 10\\\Rightarrow 5x=10\\\Rightarrow x = 2[/tex]

ST = 3[tex]x[/tex] = 3 [tex]\times[/tex] 2 = 6 cm

Therefore, the answer is:

Distance between S and T is 6 cm.

If the space between R and S is 2x, the space between S and T is 3x, and RT is 10 centimeters long, then ST is 6 centimeters

Point S lies between points R and T on Line segment RT

RT   =  RS   +  ST

The space between R and S is 2x

That is, RS  =  2x

The space between S and T is 3x

That is, ST  =  3x

RT is 10 centimeters long

RT  =  10cm

Substitute RT = 10, ST = 3x and RS = 2x into the equation RT = RS + ST

10  =  2x  +  3x

10   =  5x

x  =  10/5

x   =  2

If x = 2, then

ST  =  3x

ST = 3(2)

ST =  6 centimeters

Answer:

6 * (x - 1.50) = 52.50 ; 10.25

Step-by-step explanation:

Given that :

Number of tickets purchased = 6

Coupon off per ticket = 1.50

Total Amount paid for tickets = $52.50

Let x = initial price of ticket :

Number of tickets purchased * (Initial ticket price - coupon) = total amount paid

6 * (x - 1.50) = 52.50

6x - 9 = 52.50

6x = 52.50 + 9

6x = 61.50

x = 61.50 / 6

x = 10.25

Hence, initial price of ticket = $10.25
