Solve the inequality.

−2x+27>21

Which answer represents the solution set?

A. x<−3

B. x>−3

C. x<3

D. x>3

Answer:

Step-by-step explanation:

Check boxes 1 and 4 (these two are true!).

1. Quadrant I is the top right quadrant on the graph. All values for x and y are positive in quadrant 1. Quadrant III is the bottom left and both coordinates (x,y) would always be negative.

4. Multiplying a number by itself is the same as squaring that number or raising it to the power of 2. In all cases, squaring a number results in a positive value. Therefore, no matter if the coordinates are positive or negative, the new coordinates will both be positive after being multiplied by themselves. This will result in the new coordinates being in Quadrant I.

Answer:4/5

Step-by-step explanation:

I think it's 4/5 because the number 3 is only one number of 5. And if you subtract 5-1, you'll get 4.

Answer:

120m^2

Step-by-step explanation:

Let's start with the bottom. Since the height, base and width are all 4m, we can say that one square = 16 m^2.

There are 5 squares (counting the bottom), and 16 * 5 = 80.

Now the top triangles. We can split the bigger triangle in half. The base is 4m, you can tell from the bottom. To find the area of the triangle, split 4 in half to find the base of the smaller triangles, which equals 2.

Now for the smaller triangles, the base is 2 and the height is 5. We know that to find a triangle's area, you do (b * h)/2, which is (2*5)/2 = 5.

The big triangle is 2 of the small triangles, so you can multiply the smaller triangle's area by 2, which is 5 * 2 = 10.

There are 4 identical triangles at the top-- so 10 * 4 = 40.

80 + 40 = 120.

Hope this helps!

Answer:

11.6667 mi/h

Step-by-step explanation:

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Option 3

Step-by-step explanation:

We want to work out the surface-area

This is a cylinder and the formula for the surface area of a cylinder is :

2πrh+2πr^2

^ means to the power of

The radius is 15

The length is 18

2(3.14)(15)(18) + 2(3.14){15}^2

Part 1:

(6.28)(15)(18)

(6.28)(270)

1695.6

Part 2:

First, we do the exponents,

15^2 = 225

(6.28)(225)

1413

Part 3:

1695.6 + 1413 = 3108.6

Answer: 3108.6

Answer:

V=3799.40

Step-by-step explanation:

first, let's go over the equation for finding the volume of a cylinder.

V=πr^2h

the height is 10, and the radius is 11.

we have everything we need to make the equation!

V=(3.14)(11)^2(10)

V=(3.14)(121)(10)

V=3799.40

Answer:

216

Step-by-step explanation:

The number of smaller unit cubes that could fit inside the bigger one could be calculated by dividing the Volume of the larger cube by the volume of the smaller cubes.

Volume of bigger cube:

[tex](1\frac{1}{2}) ^3 = \frac{27}{8}[/tex]

Volume of smaller cube:

[tex](\frac{1}{4} )^3=\frac{1}{64}[/tex]

[tex]\frac{27}{8} /\frac{1}{64} =\frac{27}{8}*64=216[/tex]

Answer:

Step-by-step explanation:

Take 1 1/2 * 1 1/2 * 1 1/2 = 27/8 (3.375) in which would be the volume  and then all you have to do is put 1/4 into 27/8 how many overtimes (3 3/8)

(I would wait until you have more answers because I'm not that great at math but I'm here to practice)

This is a triangular pyramid and has 4 faces.

Answer:

5

Step-by-step explanation:

Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.

On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.

For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges

Answer:

a. 8,953.5 seconds

b. 14,400 seconds (check note)

Step-by-step explanation:

a.

y=-4x

y=-35814 (negative because this is underwater)

-35814=-4x

8953.5

The model suggests it would take 8,953.5 seconds for DeepSea Challenger to reach the bottom (2.487083333 hours, or about 2 hours and 30 minutes).

b.

y=4x

x=3600 (positive because the vessel is rising)

4(3600)

14400

It took 14,400 seconds for the DeepSea Challenger to ascend to the surface.

[also note: I'm not sure if the second question is asking for how many seconds it takes to ascend to the surface with reference to the 4 seconds in the previous question (which is how I answered part b) or if it's asking how many seconds 1 hour is, and in that case. the answer is 3,600 seconds. I hope this helps and sorry if it's unclear!]

Surface area =

2(5.5x4) in² + 2(5.5x2) in² + 2(4x2) in²

= 44 in² + 22 in² + 16 in²

= 82 in²

Answer:

75% i think because each pair is 25% and the whole thing makes up 100%

Step-by-step explanation:

The graph G represent "y is less than 5 more than the product of x and -3?".

We have the statement as

"y is less than 5 more than the product of x and -3"

Now, writing the mathematical inequality we get

y < -3x + 5

Here, the slope of the line will be negative.

and, the y-intercept is 5, meaning that the line will intersect the y-axis at the point (0, 5).

Thus, the graph G represent the inequality.
