Step-by-step explanation:

Answer: 120ft

Step-by-step explanation:

To work out the area of this composite shape you would have to work out the two shapes separately. The shape could be split into 2 rectangles.

The formula for the area of a rectangle is base x height.

So, to work out the area of the living room you have to do 15x7=105

Then to work out the area of the foyer, you would have to do 3x5=15

Because you want the area of both of the shapes together, you have to add the two areas of the rectangles together.

So 105+15=120

Answer: 44

Step-by-step explanation:

since the inscribed angle is half of true arc measure, (3x+10)= 2(2x-17).

when you work this out, you get 44 as x.

The value of x from the given figure is 44°. Therefore, option B is the correct answer.

The angle subtended by an arc at the center is twice the angle subtended at the circumference . More simply, the angle at the center is double the angle at the circumference.

From the given figure,

Angle at circumference is (2x-17)° and angle at center is (3x+10)°.

Now, (3x+10)°=2(2x-17)°

3x+10=4x-34

4x-3x=10+34

x=44°

Therefore, option B is the correct answer.

The missing terms in the equation  (__ + 7) + (2x - 6) = - 4x + 1 is - 6x.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, An equation (__ + 7) + (2x - 6) = - 4x + 1.

Simplifying the LHS we have,

__ + 7 + 2x - 6.

__ 2x + 1.

Now, The difference between 2x and - 4x is - 6x.

Therefore, The complete equation where LHS = RHS would be,

(- 6x + 7) + (2x - 6) = - 4x = 1.

Step-by-step explanation:

≥ means that it is greater than or equal to.

Any set that has all numbers over or equal to -5 would be correct, meaning that -5, -4.5, and -3 would be correct.

Hope this helps. Have a nice day.

Inequalities help us to compare two unequal expressions. The set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

As we need to find the values that will satisfy the inequality n≥-5, therefore, we need values that are greater than or equal to -5.

Hence, the set of values makes the inequality n > -5 true is {-5, -4.5, -3}.

40 people came to the Center to hike

Step-by-step explanation:

30 people took classes

22 did bird watching

12 did both

to solve, take 12 and subtract it from each one:

⇒ 30 - 12 = 18

⇒ 22 - 12 = 10

18 people only took classes

10 people only did bird watching

12 people did both

18 + 10 + 12 = 40

The measurement 345.58 cm² is the closest to the total surface area of the can in square centimeters.

The correct option is A.

A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.

Given:

A can in the shape of a cylinder has a diameter of 10 centimeters and a height of 6 centimeters.

The surface area of the cylinder,

= 2π r h + 2π r²

= 2 (3.14)(5)(6) + 2 (3.14) (25)

= 345.4 square centimeters.

Therefore, 345.58 cm² is the closest value.

Answer:

[see below]

Step-by-step explanation:

A system of equations with no solution would show parallel  lines. We just have make a equation that is parallel to the original equation.

The slope of 2x + 8y = 12 is [tex]-\frac{1}{4}[/tex], and it's y-intercept is [tex]\frac{3}{2}[/tex].

Since parallel lines have the same slope but not the same y-intercept, I would use [tex]y=-\frac{1}{4}x+3[/tex].

Any equation that has -1/4 as the slope would work.  

When graphed together, they show as a system with no solution.
