Answer:

z < 15

Step-by-step explanation:

z + 9 < 24

z + 9 - 9 < 24 - 9

z < 15

Answer:

z < 15

Step-by-step explanation:

To solve for z, you need to isolate it on one side of the equal sign, or in this case, the < sign.

If you subtract 9 from the left side of the equation, z will be alone. But whatever you do to one side you have to do to the other. So subtract 9 from 24 as well and you get z < 15

Answer:

The greatest common factor is 3.

Step-by-step explanation:

If you decompose 9 you will get 3*3 so 9=3*3

If you decompose 12 you will get 2*6,then you can decompose 6 which 2*3 so 12=2*2*3

If you decompose 6 you will get 2*3 so 6=2*3

What do all of these numbers have in common?The 3.

So 3 is the greatest common factor.Now you just put the 3 in front and then open the bracket and divide each of the number by 3.

9/3=3

-12x/3=4x

6y/3=23

So,this will be your answer 3(3-4x+2y)

Answer:

76 cm^2

Step-by-step explanation:

Volume of the cuboid = Length(l)×breadth(b)×Height (h)

Given that

A cuboid has a volume of 24 cm^3 and its length, breadth, and height are integers only.

prime factor of 24 = [tex]2^3\times3\times1[/tex]

24 = 2×3×2×2×1

24= 12×2×1

or 24= 6×4×1

Now, for Surface area to be maximum we have to take dimensions as

12,2,1

SA = 2(lb+lh+bh)

=2(12×2+12×1+2×1)

= 76 cm^2

Therefore, maximum area of the cuboid with diemensions, 12,2,1 = 76 unit

If I remember how to solve these questions correctly, if there is a triangle that is 45 degrees, the hypotenuse will be times the square root of 2 of the other two sides (which are equal to eachother). Hope this helped!

Answer:

[tex] \cos(45 \degree) = \frac{3 \sqrt{2} }{x} \\ x = \frac{3 \sqrt{2} }{ \cos(45 \degree) } \\ x = 6[/tex]

Answer:

490π

Step-by-step explanation:

Given data

Diameter= 14 inches

Radius= 7 inches

Height = 10 inches

The expression for the volume of a cylinder is

V= πr^h

V= π*7^2*10

V= 490π

Hence the volume is 490π

Answer:

Answers below!

Step-by-step explanation:

-9 x -5 = 45

45 x - 6 = -270

-270 x -3 = 810

The answer is positive because a negative multiplied by a negative equals a positive number.

-9 x -5 = 45

45 x 6 = 270

270 x -3 = -810

This answer is negative because a negative multiplied by a positive  equals a negative number.

Answer:

The line does not represent a direct variation because it does not go through the origin.

Answer:

<K = 67degrees

Step-by-step explanation:

From the parallelogram given, the opposite angles are equal i.e <L = <J

Given

<L = 5x + 18

<J = 7x - 20

Equating both sides

5x +  18 = 7x - 20

Collect the like terms

5x - 7x = -20 -18

-2x = -38

x = 38/2

x = 19

Also <J + <K = 180

7x - 20 + <K = 180

7(19) - 20 + <K = 180

133  - 20 + <K = 180

113 + <K = 180

<K = 180 - 113

<K = 67degrees

Answer:

37.7 cm

Step-by-step explanation:

C=2πr=2·π·6≈37.69911

Answer:

37.68 cm.

Step-by-step explanation:

The formula for circumference of a circle is: πd (diameter)

The radius of this circle is 6 centimeters.

To find the diameter, multiply the radius by 2.

6 × 2 = 12.

12 is the diameter.

Lastly, multiply the diameter by pi.

**3.14 IS A SUBSTITUTE FOR PI**

3.14 = 37.68.

Therefore, the circumference of this circle is 37.68 cm.

Answer:

6 x 14 = 84

84 x 2(since there are two small rectangles) = 168

22 x 6 = 132

132 x 2 = 264

264 x 2(since there are two of the same shape) = 528

22 x 14 = 308

308  x 2(since there are two of the same shape) = 616

Now we add up all the areas:

168 + 528 + 616 = 1312 square cm is your answer.

Answer:

Number of people wearing a red t-shirt= 14,500

Step-by-step explanation:

Giving the following information:

Number of people= 50,000

Percentage of people using red t-shirt= 29%

To calculate the number of people wearing a red t-shirt, we need to use the following formula:

Number of people wearing a red t-shirt= number of people*percentage of people wearing a red t-shirt

Number of people wearing a red t-shirt= 50,000*0.29

Number of people wearing a red t-shirt= 14,500

Step-by-step explanation:

Answer:

60 minutes

Step-by-step explanation:

Here is the complete question

Caylan is making baked goods for a charity bake sale. He places a tray of scones, a tray of muffins, and a tray of cookies in the oven. The scones bake for 15 minutes, the muffins bake for 12 minutes, and the cookies bake for 10 minutes. When one tray is done, he removes it and replaces it with another tray of the same item. How many minutes after Caylan puts the trays in the oven will he first remove the scones, muffins, and cookies at the same time? ? minutes​

The multiples for scones = 15 = 3,5

The multiples for muffins = 12 =2, 2,2,3

The multiples for cookies = 2, 5

Lowest common multiple = 2 x 2 x 3 x 5 = 60 minutes

to determine the time , calculate the lowest common multiple of 12, 15 and 10

Answer:

60 - This is due to the times of each and what time you would take them out.

Answer:

(4.6, 4)

Step-by-step explanation:

Given the coordinates (3,2) and (7, 7) partitioned between 3:2

M(X,Y) = [(ax1+bx2/a+b, ay1+by2/a+b)]

X = 3(3)+2(7)/3+2

X = 9+14/5

X = 23/5

X = 4.6

Similarly;

Y = 3(2) + 2(7)/3+2

Y = 6+14/5

Y = 20/5

Y = 4

Hence the required coordinate is (4.6, 4)
