The value of the expression  21 ÷ 3 + (8 - 2 ÷ 2) is 14.

To simplify the expression 21 ÷ 3 + (8 - 2 ÷ 2).

we need to follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

The expression inside the parentheses should be solved first.

8 - 2 ÷ 2.

First, divide 2 by 2, which equals 1.

Then, subtract 1 from 8: 8 - 1 = 7.

Now, we have 21 ÷ 3 + 7.

Divide 21 by 3, which equals 7.

Finally, add 7 + 7, which equals 14.

Therefore, the simplified expression 21 ÷ 3 + (8 - 2 ÷ 2) equals 14.

Answer:

889.66 cm^3

Step-by-step explanation:

here's your solution

=> radius of cylinder = 5 cm

=> height of cylinder => 8 cm

=> radius of hemisphere = 5 cm

=> volume of toy = ( vol of cylinder + vol of hemisphere)

=> volume of cylinder = πr^2h

=> putting value , = 22/7*5*5*8

=> volume = 628 cm^3

=> volume of hemisphere = 2/3πr^3

=> putting value , = 2/3*22/7*5^3

=> volume of hemisphere = 261.66 cm^3

=> volume of toy = (628 + 261.66)cm^3

=> volume = 889.66 cm^3

Cone volume = (1/3)πr2h

Cylinder volume = πr2h

So, the cylinder's volume is 3 times that of the cone.  

Answer:

p = 3.8

Step-by-step explanation:

11 - 7.2 = 3.8

Answer:

p = 3.8

Step-by-step explanation:

We have the equation p + 7.2 = 11 and are asked to solve for "p".

To do so, all we need to do is isolate p :

p + 7.2 = 11

Subtract 7.2 from both sides :

p = 3.8

Six of those will fit on the board

Step-by-step explanation:

Answer:

The largest tile she can use is a 8 inches by 8 inches tile.

Step-by-step explanation:

Rosa is making a game board that is 16 inches by 24 inches.

She wants to use square tiles.

The area of the game board (area of  a rectangle) is equal to length times width.

∴ Area = 16 inches × 24 inches = 384 square inches

The prime factors of 384 are; 2^7 × 3

We can put it as;

2^6 × 6 = 384

The square root of 2^6 is 2^3 = 8

So Rosa will need six square tiles of 8 inches by 8 inches each.

Hence the largest tile she can use is a 8 inches by 8 inches tile.

Step-by-step explanation:

I think, hope this helps

The equation for the number 40 is 5 times as many as 8 is; 40=5×8

An equation represents equality of two or more mathematical expression.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

Solutions to an equation are those values of the variables involved in that equation for which the equation is true.

We are given that the number 40 is 5 times as many as 8

40 is 5 times as many as 8 means

5×8 = 40

Then the equation will be;

40=5×8

tan 29° = x/10

=> x = tan 29° × 10

=> x ≈ 5.5

Answer:

By the math, x = 10°

Here's my issue though, the top angle is x - 15°. That would be an angle of -5° which is impossible.

Step-by-step explanation:

x - 15 + 2x + 25 + 180 - 4x = 180°

From the values of 3 and five, we can assume that the function of the table is Y=x+2.

But if we move to the next value pairs, that function is false.

10=6+2 that isn't correct.

If you apply this to all the pairs in the table you will find that there is not a function that represents the values given. Therefore, the first option is correct.

Answer:1182.4432≈1182

Step-by-step explanation:

The population of bacteria in the culture after 2 hours is approximately 1,248.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Given that the initial population of bacteria is [tex]P_0[/tex] = 970, and the doubling time is d = 7 hours.

Using the formula,

P+ = [tex]P_0[/tex] x [tex]2^{t/d)[/tex]

We can calculate the population of bacteria after 2 hours as follows.

P+ = 970 x [tex]2^{2/7}[/tex]

= 1,248.4

Rounding this to the nearest whole number, the population of bacteria in the culture after 2 hours is approximately 1,248.

Thus,

The population of bacteria in the culture after 2 hours is approximately 1,248.
