Need some answers with this question​

a) x+1+x+1+x+1+x+1=56 x=6.5

b) 2(6.5)+1=14cm

Answer:

162 square inches

Step-by-step explanation:

9*12*1.5

Answer:

162 cubic inches

Step-by-step explanation:

9 times 12 times 1.5

Answer:

52

Step-by-step explanation:

Using the reverse Pythagorean Theorem we can get the answer quite easily. If  A^2 + B^2 = C^2, then by that same logic, C^2 - A^2 = B^2. That means 62^2, or 3844, minus 39^2, or 1521, equals 2323. The square root of that is 52.

Hope that this helps!

Answer:

1/3*1/6 is ur answer.

1/18

Answer:

z = 137 degrees

Step-by-step explanation:

Angle 43 and angle z make a straight line, which is 180 degrees

43+z = 180

Subtract 43 from each side

43+z-43 = 180-43

z =137

Answer:

[tex]A=172.04\ in^2[/tex]

Step-by-step explanation:

Given that,

The side length of a regular pentagon = 10 inches

The distance from the center to a vertex of 10 inches

The formula for the area of a regular pentagon is given by :

[tex]A=\dfrac{1}{4}\sqrt{5(5+2\sqrt{5} } }\ a^2[/tex]

Put a = 10

So,

[tex]A=\dfrac{1}{4}\times \sqrt{5(5+2\sqrt{5} )} \times 10^2\\\\A=172.04\ in^2[/tex]

So, the area of a regular pentagon is equal to [tex]172.04\ in^2[/tex].

Answer: 34 in^3

Step-by-step explanation:

Surface area of triangle = 1/2 x  3.4 x 2.5 = 4.25

To find the volume of the prism, multiply the surface area of the triangle by length.

So 4.25 x 8 = 34 in^3

Answer: 4950 cubic centimeters.

Step-by-step explanation:

We know that, the volume of box = Base area x height

Given: area of the base of a box  = 825 sq. centimeters

height = 6 centimeters.

Then, Volume of the box in cubic centimeters = 825 x 6

= 4950 cubic centimeters.

hence, the volume of the box in cubic centimeters = 4950 cubic centimeters.

Answer: 5 : 8

Step-by-step explanation:

The ratio of seventh graders to sixth grader on the team is 5 : 3.

Assuming that only seventh and sixth graders are in the team, the total number of chess players at the most simple basis is:

= Number of seventh grade students in ratio + Number of sixth grade students in ratio

= 5 + 3

= 8 students

There are 5 seventh graders so the ratio will be:

= 5 : 8

Note: The chess team will most likely have more than 8 members but the  ratio of seventh graders to total chess players will still be 5 : 8.

See answers below

Step-by-step explanation:

Expand the brackets. 7 ( 5 + g ) 11 ( 3s – 4 ) 4 ( 4 – x ) 8 ( 6 + 4w )

We will expand each of the bracket using distributive property

For the expression 7(5+g)

7(5)+7g

= 35+7g

For the expression 11(3s-4)

= 11(3s)-11(4)

= 33s-44

For the expression 4(4-x)

= 4(4)-4x

= 16-4x

For the expression 8(6+4w)

= 8(6)+8(4w)

= 48+32w

Answer:

12.57 in^3

Step-by-step explanation:

The easiest way to do this is to find the area of the circle surface and multiply it by the height

to find area the formula is pi r^2 and we are given the radius

so we plug in pi(2^2)=pi(4)= roughly 12.57

then we multiply the area by the height which is 1 so it would be the same

12.57(1)=12.57

Answer:      x=-5

Step-by-step explanation:

Distribute

6(x+3)-1(x+4)=-11

6x+ 18-1(x+4)=-11

6x +18-x-4=-11

Subtract the numbers

6x +18-x-4=-11

6x +14-x=-11

Combine like terms

6x +14-x=-11

5x +14=-11

subtract 14 from both sides of the equation

5x +14=-11

5x +=14-14 = -11 -14

simplify

5x=-25

divide both sides

x=-5

Answer:

D let me know if you need explanation

Step-by-step explanation:

D

Step-by-step explanation:

the slope for the main equation is 2

to get the perpendicular equation

slope=-1/m

so slope=-1/2

when you break the slope at equation D

you will get -1/2

Answer:

The home is worth $424,528 today

Step-by-step explanation:

To get the worth of the home today, we are going to use the exponential formula

We have this as follows;

A = P(1 + r)^t

where A is the value of the house after some time t

P is the initial value the home was worth which is $160,000

r is the rate of increase in the price of the home which is 5% = 5/100 = 0.05

t is the number of years which is 20

substituting these values;

A = 160,000(1 + 0.05)^20

A = $424,528
