Step-by-step explanation:

The options 1,2 and 5 are the correct answer.

The given equation is 1.23/\(10^1\)=0.123.

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Now,

1) 1.23/\(10^1\)=0.123

Here LHS=RHS

2) 123/100=1.23

Here LHS=RHS

3) 12.3/\(10^0\)=1.23

⇒ 12.3/1=12.3

So, LHS≠RHS

4) 0.123/10=1.23

⇒ 0.123/10 = 0.0123

So, LHS≠RHS

5) 1230/10³=1.23

⇒ 1230/1000

= 1.23

Here LHS=RHS

Therefore, the options 1,2 and 5 are the correct answer.

Answer:

r = 3m

Step-by-step explanation:

Formula for the volume of a sphere: V = \(\frac{4}{3}\)\(\pi\)\(r^{3}\)

We want to find the radius so we use algebra to rearrange the equation to make the radius (r) the subject of the equation

Divide both sides by \(\frac{4}{3}\)

\(\frac{3V}{4}\) = \(\pi\)\(r^{3}\)

Divide both sides by \(\pi\)

\(\frac{3V}{4\pi }\) = \(r^{3}\)

Take the cube root of both sides

\(\sqrt[3]{\frac{3V}{4\pi } }\)= r

Substitute V = 36\(\pi\) into the equation

r = \(\sqrt[3]{\frac{3(36\pi) }{4\pi } }\)

Expand the bracket

r = \(\sqrt[3]{\frac{108\pi }{4\pi } }\)

Divide 108\(\pi\) by 4\(\pi\) (For this, the two \(\pi\) in the numerator and denominator cancel each other out, and you only need to divide 108/4)

r = \(\sqrt[3]{27}\)

The cube root of 27 is 3, because \(3^{3}\) = 3 x 3 x 3 = 27

r = 3

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Pete and Teegan each put an amount of $P in a new bank account.

Teegan's account earns 2.75% simple interest, earned $2.20 in interest after one year.

Write p x 2.75/100 = 2.20 so p = 80$ and $80 in Pete's account earns 5% simple interest.

after one year Pete will earn as interest 80 x 5/100 = 4$

Answer:

\(7^{2} =49\)

Step-by-step explanation:

Exponents mean a number, or variable multiplying itself by what the power is.

Note:

\(7^{0} = 1\\7^{1} =7\)

In this problem, 7 is being multiplied to the power of 2. (7 · 7)

Solve:

\(7(7) = 49\)

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Mean = 16

Step-by-step explanation:

MEAN can be find bg the sum of all score divided by the amount of the score.

Mean = total amount / number of amount

Total amount = 2 + 3 + 5 + 9 + 17+ 22 + 31 + 39

= 128

number of amount = 2, 3, 5, 9, 17, 22, 31, 39

= 8

Then we can calculate mean as

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4
