Step-by-step explanation:

Rational numbers are denoted Q Since −3 can be written as −31  it could be argued that −3 is also a real number.

answer:

yes

explanation:

rational numbers are are numbers that can be expressed as a fraction or ratio of two integers. they can be represented as a integer, fraction, terminating decimal, or repeating decimal. In this case -3 is an integer making it rational.

Answer:

Step-by-step explanation:

Two cylinders are similar. The heights of the cylinders are 15 cm and 12 cm. If the surface area of the smaller cylinder is 487 cm square. find the surface area of the larger cylinder.

Height of the smaller cylinder = 12cm

Area of the smaller cylinder = x

Height is the bigger cylinder = 15cm

Area of the bigger cylinder = 487cm²

We can find the radius of the bigger cylinder

Radius of the bigger cylinder = 4.07 cm

Hence: we form our proportion to find radius of Smaller cylinder

12/15 = x/4.07

Cross Multiply

15x = 12 × 4.07

x = 12 × 4.07/15

x = 3.256 cm

Answer:

256

Step-by-step explanation:

4^4^4 = 4^(4^4) = 4^256

so written in base 4, there will be 256 zeroes after a 1.

This translates to approximately 154 digits in decimal.

Just like 2^2^2 =  2^4

there will be four zeroes after a 1.

2^2^2=2^(2^2) = 2^4 = 16 = 10000 (16 in base 2).

Answer:

4³=4*4*4 is a required expanded form.

Answer:

Step-by-step explanation:

use pythagoras theorem

a^2+b^2=c^2

g^2+g^2=24^2

2g^2=576

g^2=576/2

g^2=288

g=[tex]\sqrt{288}[/tex]

g=12[tex]\sqrt{2}[/tex]

Answer:

No, they can't.

Step-by-step explanation:

In geometry, cubic units can be defined as the units used to measure volume. The volume of a unit cube whose length, width and height are 1 unit each is 1 cubic unit. The length, width and height of the rectangular prism can be measured by counting the number of unit cubes.

Answer:

3.12mm= 31,2cm

3.12= 0.312m

3.12 = 0.000312km

Answer:

positive because 2 negatives being multiplied=a positive number

hope this helps

have a good day :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

the expression has positive number because along with multiplying the number we should multiply sign too so when we multiply "-" * "-" it gives us "+"(positive ).

Answer:

x= 4, y = -1

Step-by-step explanation:

2x-3y=11

3x+3y=9

do addition and you should get

5x=20

x=4

plug in x into any equation

12+3y=9

3y= -3

y=-1

Answer:

2

Step-by-step explanation:

You would make 1/4 into 4/1 and then you would multiply 1/2 by 4/1 to get 4/2 which is equal to 2

1/2 * 4/1 = 4/2 = 2

1 * 4 = 4

2 * 1 = 2

Answer:

7/10

Step-by-step explanation:

1. Simplify - 1 3/2 - 1 4/5

2. Subtract the whole numbers to make it easier - 1-1 = 0

3. Combine fractions - 3/2 - 4/5 = 7/10

4. 0 + 7/10 = 7/10

So, the final answer is 7/10.

Hope this helps! :)

Also you should use Symbolab, it's really helpful

This equation is equal to 7/10 or 0.7

Answer:

I believe 90

Step-by-step explanation:

because if you take away 25 (40 pounds) from 100, you divide 100 by 2 to see how many pounds that are 2 $ fit in 100

100/2=50 (pounds)

so 50pounds + the 40pounds (which was the 25$ i took off to make it easier) =90 pounds

Answer:

8.66

Step-by-step explanation:

Answer:

the proportional relationship represented by the table has a higher rate of change (15)

Step-by-step explanation:

✔️The rate of y = 12x is 12

✔️Rate of the table of values given is:

y/x = 30/2 = 60/4 = 75/5 = 15

Rate of change for the table of values = 15

✔️Rate of change for the graph given can be found using the coordinates of any point on the line:

Using (1, 4),

rate of change = y/x = 4/1 = 4

✅Therefore we can conclude that the proportional relationship represented by the table has a higher rate of change (15)

Answer:

2.5x=26-1

x=25/2.5

x=10

Step-by-step explanation:

Answer:

I assume you're solving for x, so the answer is 10

Step-by-step explanation:

First you isolate the x, so you need to subtract one from both sides, which results in the equation 2.5x = 25, and then you divide 25 by 2.5, which gives you x = 10
