If the original quantity is 10 and the new quantity is 13, what is the percent increase?

Answers

Answer:

30% increase

Step-by-step explanation:

subtract original quantity from new quantity: 13 - 10 = 3

divide the difference by original quantity: 3/10 = 0.30

convert that result to percentage by moving decimal place over twice to the right.

You're done! Answer = 30%

Answer:

30%

Step-by-step explanation

13 is a 30% increase of 10.

Zen wants to fill a window box with soil. The length of the window box is 5 feet, width is 6 inches, and height is 9 inches. Each bag of soil contains 0.625 cubic foot of soil. How many bags of soil will Zen need to fill the window box completely?[1 foot = 12 inches]

---------------------------------

Answers

Answer:

$3\ bags$

Step-by-step explanation:

we know that

The volume of the windows box is equal to

$V=lwh$

where

l is the length side of the box

w is the width side of the box

h is the height of the box

In this problem we have

$l=5\ ft$

$w=6\ in$ ------> convert to feet -----> $6/12=0.5\ ft$

$h=9\ in$ ------> convert to feet -----> $9/12=0.75\ ft$

substitute the values

$V=5*0.5*0.75=1.875\ ft^(3)$

Find how many bags of soil will Zen need to fill the window box completely

by proportion

$(1)/(0.625)(bag)/(ft^(3))=(x)/(1.875)(bag)/(ft^(3))$

$x=1.875/0.625\nx= 3\ bags$

Hello,

Volume of the window box=5*1/2*3/4=15/8 (ft^3)
Volume of the bag=0.625= 5/8 (ft^3)

Number of bags of soil= (15/8)/(5/8)=15/8* 8/5=3 .

What are the solutions to the quadratic equation x2 – 16 = 0?x = 2 and x = –2
x = 4 and x = –4
x = 8 and x = –8
x = 16 and x = –16

Answers

The correct statement is that the solution of this equation x² – 16 = 0, is 4 and -4.

What is a quadratic equation?

It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation. The general form of the quadratic equation is ax² + bx + c = 0

Given

The quadratic equation x² – 16 = 0

To find

The root of the quadratic equtaion?

How do find the solutions to the quadratic equation?

The quadratic equation x² – 16 = 0

We know the formula,

a² - b² = ( a - b ) ( a + b )

Then

x² – 4² = 0

(x - 4)(x + 4) = 0

x = 4 and -4

Thus, the solution of this equation x² – 16 = 0, is 4 and -4.

Answer: The correct option is (B) x = 4 and x = -4.

Step-by-step explanation: We are given to find the solutions to the following quadratic equation :

$x^2-16=0~~~~~~~~~~~~~~~~~~~~~(i)$

Since the coefficient of x is zero in the given equation, so we will be using the method of square root to solve the equation.

From equation (i), we have

$x^2-16=0\n\n\Rightarrow x^2=16\n\n\Rightarrow x=\pm√(16)~~~~~~~\textup{[taking square root on both sides]}\n\n\Rightarrow x=\pm4\n\n\Rightarrow x=4,~-4.$

Thus, the required solution is x = 4 and x = -4.

Option (B) is correct.

Using the graph of f(x) = log10x below, approximate the value of y in the equation 10y = 6

Answers

The given function is

f(x)= log 10 x

Taking base as 10

$y=\log_(10)10 +\log_(10)x$ →→Using the property of, log a b= log a + log b

→y = 1 + $\log_(10)x$ as, $\log_(10)10=1$

we have to approximate the value of y in the equation

→10 y = 6

→y= $(6)/(10)$

$(6)/(10)$ = 1 + $\log_(10)x$

$\log_(10)x$ = $(-4)/(10)$

x= $(10)^{(-4)/(10)}$ = $(10)^(-0.4)$ =0.398

Solving graphically,

we get , x= 0.398 for , y= $(6)/(10)$ =.6

f(x) = ㏒(10x)
f(x) = ㏒₁₀(10x)

10y = 6
10 10
y = 0.6

f(x) = ㏒₁₀(10x)
0.6 = ㏒₁₀(10x)
$10^(0.6) = 10x$
$10^{(3)/(5)} = 10x$
$\sqrt[5]{10^(3)} = 10x$
$\sqrt[5]{1000} = 10x$
$\frac{\sqrt[5]{1000}}{10} = x$
$(3.98)/(10) \approx x$
$0.398 \approx x$

I am a quadrilateral with all my sides equal in length. none of my angles equals 90. what am i?

Answers

You are a rhombus. A rhombus is a quadrilateral with all sides equal in length but none of its angles are 90 degrees.

A rhombus is a four-sided polygon with all sides of equal length, making it a special type of parallelogram. Unlike a square, its angles are not right angles (90 degrees).

Rhombi have two pairs of opposite sides parallel, and their diagonals bisect each other at right angles. The rhombus's symmetry and equal side lengths create a balanced and diamond-shaped figure. It is a versatile shape found in various applications, from diamond gemstones to kite designs.

Due to its unique properties, a rhombus is commonly used in mathematics, geometry, and design. Its distinct features make it easily recognizable and distinguishable from other quadrilaterals.
