Answer:

1. (d) 151 in

2. (a) 43.3 in

Step-by-step explanation:

1. The circumference is ...

C = 2πr

C = 2(3.14)(24 in) = 150.72 in

C ≈ 151 in

2. C = 2πr

r = C/(2π) = 272.2 in/(2·3.14) ≈ 43.3439 in

r ≈ 43.3 in

Answer 2

Answer:

1.Option 4

2.option 1

Step-by-step explanation:

1.circumference of circle=2πr=2π×24=48π or 151in

2.circumference of circle=2πr

272.2=2πr

r=272.2/(2π)=43.3in

What is the length of one side of a cube that has a surface area of 2400 square mm?
a. 20.00 mm
b. 24.29 mm
c. 17.32 mm
d. 8.16 mm

Answers

Answer:

A)20.00mm

Step-by-step explanation:

since the cube has 6 faces divide it by 6.

= 2400 ÷ 6

=400

1 face = 400 area

since the surface of the cube is square and its area is 'side square'

find the square root of 400

which is 20 cm (side)

Also, I took the test and got it correct.

Answer:

a) 20.00mm

Step-by-step explanation:

Since the cube has 6 faces divide it by 6.

Can Anyone please explain what linear equations are

Answers

Answer:

In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

Evaluate the expression 6x + 21y when Y = 4 x=3

Answers

Answer:

102

Step-by-step explanation:

You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.

Answer: 102

Step-by-step explanation: 6x + 2y

6(3) + 21(4)

18 + 84

102

basically you just plug in 4 where it says y in the equation and plug in 3 where it says x in the equation and solve :))

8x + 2 = 72 + x
solve for x

Answers

Answer: x=10

Step-by-step explanation:

8x+2=72+x

1. Move like terms

8x-x=72-2

2.Collect like terms and calculate

7x=70

3. divide both sides

The answer to this question would be x=10.

Solve the system using elimination

Answers

Answer:

x = 5

y = 1/4

Step-by-step explanation:

Let a = 1/x

b = 1/y

Then the equations are

(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2

-10a - 16b = -66

-20b = - 80

b = 4 5a + 8(4) = 33

5a + 32 = 33

5a = 1

a = 1/5

a = 1/x = 1/(1/5) x = 5

b = 1/y = 4 y = 1/4

How do you do 4 divided by 0.8 in place value

Answers

Answer:

Step-by-step explanation:

because that is the correct answer

4 divided by 0.8 is equal to 5.

To divide 4 by 0.8 using place value, you can follow these way

Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.

Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal

0.4 x 10 = 40( multiplying the tip by 10)

0.8 x 10 = 8( multiplying the divisor by 10)

Now we've the division problem as 40 divided by 8.

Divide the converted tip by the converted divisor

= 40 ÷ 8

= 5

Thus, 4 divided by 0.8 is equal to 5.

Can someone please help me with this?

9514 1404 393

Answer:

1.411.99

Step-by-step explanation:

The Pythagorean theorem (see Hint) tells you the length of the hypotenuse (c) is ...

c² = 1² + 1² = 2

c = √2 ≈ 1.4142136 . . . units

The estimated value of the length of the hypotenuse is 1.41 units.

Of course the shaded square will have an area that is the square of that value:

area = s² ≈ 1.41² ≈ 1.99 . . . . . rounded to hundredths

The estimated area of the square is 1.99 square units.

Additional comment

Of course, we don't have to estimate. We can use the exact value of the side length to determine the shaded square has an area of ...

area = s² = (√2)² = 2 . . . . exactly

We can also get there by recognizing that the lengths of 1 represent half the length of each of the diagonals of the square. That is, the square's diagonals are both of length 2. The area is half their product, so is (1/2)(2·2) = 2 square units.
