One day, a person went to a horse racing area. instead of counting the number of humans and horses, he counted 72 heads and 192 legs. how many humans and horses were there?

Answers

h-human a-horse
h+a= 72
2h+4a=192

then do h=72-a
substitute that into the second equation
2(72-a)+4a=192

multiple out
144-2a+4a=192
2a=48
a=24
substitute a into the first equation
h+24=72
h=48
humans- 48

How do you Solve by factoring

Answers

(x+3)(x+3)=8
(x^2+3x+3x+9)=8
x^2+6x+9=8

Final answer:

To solve an equation by factoring, find the factors, set them equal to zero, and solve for the variable.

Explanation:

To solve an equation by factoring, you need to find the factors of the equation and set each factor equal to zero. Then, solve each equation separately to find the values of the unknown variable. Let's take an example:

If we have the equation [tex]x^2 - 5x + 6 = 0[/tex]:

Factor the quadratic expression: (x - 2)(x - 3) = 0Set each factor equal to zero and solve: x - 2 = 0 and x - 3 = 0solve each equation separately to find the values of x: x = 2 and x = 3

This method of factoring and setting each factor equal to zero is a systematic approach to solving quadratic equations, providing a structured way to identify the solutions for the unknown variable. The application of this technique is fundamental in algebra, enabling the efficient determination of roots in quadratic expressions and contributing to a comprehensive understanding of solving equations.

Which shape has the same volume as the given rectangular prism?

Thank you!

Answers

The correct option is (a) i.e. cylinder.

This is because:
Volume of a Rectangular Prism = (Area of base * Height)
= 50 *5 = 250 cm^3

And volume of cylinder = πr^2h = 50*5 = 250cm^3

Thus, the cylinder has the same volume as the rectangular prism

Certain hot water bottles hold up to 1500 milliliters of water. how many liters are in 1500 milliliters

Answers

1,500 milliliters is equal to 1.5 liters. In the metric system, a liter is the basic unit of volume for liquids. Like the rest of the metric system, the naming system uses prefixes derived from Latin and Greek roots that tell the user what fraction or multiplier the unit uses. In this example, "milia" is "thousand" in Latin. Thus, a "milli-liter" is a thousandth of a liter. Learning these prefixes makes the use of the metric system much easier.

State how many imaginary and real zeros the function has. f(x) = x3 + 5x2 - 28x - 32

Answers

All equation has always even numbers of imaginary roots because they always come in pairs. Therefore there must be either 2 imaginary roots, or zero.

To determine the types of roots, we could try synthetic division by some of the factors of the number -32. The simplest factors are +1 or -1. Using this, we can quickly show that (x + 1) is a factor, and leaving (x² + 4x - 32) as the remainder. This remainder equation then factorises to (x - 4) (x + 8).

So to conclude there are three real zeros which are:

x = -1

x = 4

x = -8

in a 30-60-90 Blondie triangle the long leg is half the hypotenuse

A. always
B. sometimes
c never

Answers

Answer:

never

Step-by-step explanation:

In a 30 - 60 - 90 degree triangle , the common ratio is

1 : [tex]\sqrt{3}[/tex] : 2

Shorter leg that is opposite to 30 degree = 1

Longer leg that is opposite to 60 degree = [tex]\sqrt{3}[/tex]

Hypotenuse is opposite to 90 degree = 2

Shorter leg is half the length of the hypotenuse as per the ratio

Long leg is never the half of the hypotenuse

Which exponential function goes through the points (1, 8) and (4, 512)?
f(x) = 4(2)^x

f(x) = 8(2)^-x

f(x) = 4(4)^-x

f(x) = 2(4)^x

Answers

Answer:

Therefore, the correct option is: (C.) [tex]$ f(x) = 2 \cdot 4^x $[/tex]

Explanation:

To determine the exponential function that passes through the given points, we can use the general form of an exponential function:

[tex]\[ f(x) = a \cdot b^x \][/tex]

Where:

[tex]$ a $[/tex] is the initial value or the value of the function when [tex]$ x = 0 $.[/tex]

[tex]$ b $[/tex] is the base of the exponential function.

Given the points [tex]$(1, 8)$ and $(4, 512)$[/tex], we can substitute these coordinates into the general form and solve for [tex]$ a $ and $ b $.[/tex]

Using the point [tex]$(1, 8)$:[/tex]

[tex]\[ 8 = a \cdot b^1 \][/tex]

[tex]\[ 8 = a \cdot b \][/tex]

Using the point [tex]$(4, 512)$:[/tex]

[tex]\[ 512 = a \cdot b^4 \][/tex]

We can divide the equation obtained from the second point by the equation obtained from the first point to eliminate [tex]$ a $[/tex] and solve for [tex]$ b $:[/tex]

[tex]\[ \frac{512}{8} = \frac{a \cdot b^4}{a \cdot b} \][/tex]

[tex]\[ 64 = b^3 \][/tex]

Taking the cube root of both sides:

[tex]\[ b = 4 \][/tex]

Now that we have found the value of [tex]$ b $[/tex], we can substitute it back into one of the equations to find $ a $. Let's use the first point [tex]$(1, 8)$:[/tex]

[tex]\[ 8 = a \cdot 4 \][/tex]

[tex]\[ a = 2 \][/tex]

So, the exponential function that passes through the points [tex]$(1, 8)$ and $(4, 512)$[/tex] is:

[tex]\[ f(x) = 2 \cdot 4^x \][/tex]

Answers

m = 4.

The reason why is because you first have to add 0.05 and 18 together, and than multiply it by the closes number to 81.20 which is 4, and also it cannot be over 81.20.

Answers

16 + 4x = 10 + 14
16 + 4x = 24
4x = 24 - 16
4x = 8
x = 8/4
x = 2

so now you plug in what x is, which is 2, into "8x"

8x = 8 × 2
8x = 16

so your answer is 16!

For what values of x is the following inequality true? 5/7 + x/7 >(underlined) 10. PLZ HELP!!! 12 points

Answers

Hello! Thank you for your question! I will be most happy to help!

So here what we are going to do is solve for X.

Step 1: Simplify x/7

Equation at the end of step 1: 5/7 + x/7 - 10 > 0

Step 2: Simplify 5/7

Equation at the end of step 2:

5/7 + x/7 - 10 > 0

Step 3: Adding fractions which have a common denominator:

3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

5 + x / 7 = x + 5 / 7

Equation at the end of step 3:

(x + 5) / 7 - 10 > 0

Step 4: Rewriting the whole as an Equivalent Fraction:

4.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 7 as the denominator:

10 = 10 / 1 = 10 * 7 / 7

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(x+5) - (10 * 7) / 7 = x - 65 / 7

Equation at the end of step 4:

x - 65 / 7 > 0

Step 5: 5.1 Multiply both sides by 7

Solve Basic Inequality:

5.2 Add 65 to both sides

x > 65

Final answer: x > 65

A company has found that its supply function is equal to the square of the price of their product, all divided by three. The market for its products is also related to price. demand is a basic 920 units minus thirty times price, minus a quarter of the square of the price. What is the ideal price of their product, to make sure that there is neither a surplus nor a shortage? How many units will they sell at this price?

Answers

Given that the supply function for the company is equal to the square of the price of their product, all divided by three,

i.e. [tex]Q_s=\frac{p^2}{3}[/tex]

and the demand is a basic 920 units minus thirty times price, minus a quarter of the square of the price,

i.e. [tex]Q_d=920-30p- \frac{1}{4} p^2[/tex]

The ideal price of their product, to make sure that there is neither a surplus nor a shortage is the equilibrium price which is the price when supply equals demand.

i.e.
[tex]Q_s=Q_d \\ \\ \Rightarrow\frac{p^2}{3}=920-30p- \frac{1}{4} p^2 \\ \\ \Rightarrow \frac{7}{12} p^2+30p-920=0 \\ \\ \Rightarrow p= \frac{-30\pm\sqrt{30^2-4(\frac{7}{12})(-920)}}{2(\frac{7}{12})} \\ \\ =\frac{-30\pm\sqrt{900+\frac{6440}{3}}}{\frac{7}{6}}=\frac{-30\pm\sqrt{\frac{9140}{3}}}{1.1667} \\ \\ =\frac{-30\pm55.1966}{1.1667}= \frac{25.1966}{1.1667} =21.60[/tex]

Therefore, the ideal price of their product, to make sure that there is neither a surplus nor a shortage is $21.60

The number of units they will sell at this price is given by

[tex]Q= \frac{(21.60)^2}{3} \\ \\ = \frac{466.43}{3} \approx155\ units[/tex]
