- The rungs are perpendicular to the other side.

Answer:

The rungs are perpendicular to the other side.

Step-by-step explanation:

Given

The sides of ladder are parallel.Rungs is perpendicular to one side of the ladder.

Let [tex]a\parallel b[/tex]

[tex]a\perp c[/tex]

When two lines are parallel then the slopes of two lines are equal.

We can say [tex]m_1=m_2[/tex]

Where [tex]m_1[/tex]= slope of line a( side of ladder)

[tex]m_2[/tex]= solpe of line b( side of ladder)

When two lines are perpendicular then slopes of two lines are opposite reciprocal to each other.

We can say [tex]m_2=-\frac{1}{m_3}[/tex]

Where [tex]m_2[/tex]= Slope of line b

[tex]m_3 [/tex]=Slope of line c (rung)

By transitive property of equality we get

[tex]m_1=-\frac{1}{m_3}[/tex]

Hence, the slope of side of ladder  a and rung  c are opposite reciprocal to each other.Therefore , the rungs are perpendicular to the other side.

Answer:

Mr Finds burns 101 calories in 60 minutes.

Step-by-step explanation:

We were given that Mr Finds burns [tex]808[/tex] calories in [tex]8[/tex] hours.

So we can write the ratio,

[tex]808:8[/tex]

At the same rate we want to find how many calories he burns in [tex]60[/tex] minutes.

This is equivalent to asking how many calories he burns in an hour.

Let [tex]x[/tex] represent the number of calories he burns in an hour. Since this should obviously be less than 808, we divide by 8 to get,

[tex]x=\frac{808\times 1}{8}[/tex]

[tex]\Rightarrow x=101[/tex]

Therefore Mr Finds burns 101 calories in 60 minutes.

Answer:

101 calories.

Step-by-step explanation:

We are told that while hiking, Mr.Finds burns 808 Calories in 8 hours.

To find calories burn by Mr. Finds in 60 minutes let us find calories burn per hour as 1 hour equals 60 minutes.  

[tex]\text{Calories burn in 1 hour}=\frac{808\text{ Calories}}{8\text{ Hours}}[/tex]

[tex]\text{Calories burn in 1 hour}=101\frac{\text{ Calories}}{\text{ Hour}}[/tex]

Therefore, Mr. Finds will burn 101 calories in 1 hour or 60 minutes.

An infant sleep more than 2,380 minutes to adult sleep.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

An adult sleeps about 480 minutes per day.

An infant sleeps about 820 minutes per day.

Now,

An infant sleeps in a week = 7 x 820

                                         = 5,740

And, An adult sleep in a week = 7 x 480

                                               = 3,360

So, An infant sleeps more than adult in a week = 5,740 - 3,360

                                                                         = 2,380 minutes.

Thus, An infant sleep more than 2,380 minutes to adult sleep.

The value of x will change because that is the price of the almonds

Therefore mx will change

And the value of mx+b will decrease because the price is cheaper

Answer:

The correct statements are :

1. The value of mx will change.

2. The value of m will change.

3. The value of mx+b will decrease.

Step-by-step explanation:

Todd needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. So, price of x ounces becomes = mx

The total cost of the other ingredients is b dollars.

Hence, total cost is given as = [tex]mx+b[/tex]

Now, Todd later finds almonds in the bulk section that are half the price of those in the baking section.

So, now price is :[tex]\frac{m}{2}[/tex]

And total price for 'x' ounce will become: [tex]\frac{mx}{2}+b[/tex] dollars.

Therefore, if Todd purchases the almonds in the bulk section, the total cost  will decrease.

The correct statements are :

1. The value of mx will change.

2. The value of m will change.

3. The value of mx+b will decrease.

Answer:

August 20.

Step-by-step explanation:

1. The problem says that the invoice date is June 29 and terms of sale of [tex]\frac{4}{20}[/tex] EOM. This means that if the payment is made 20 days from the end of the month, a percent of 4% may be taken as cash discount.

2. If the number of days in that month is greater than 25, you must add another month. Therefore, you must add July and 20 days of August.

3. Therefore, the discount date is August 20.

Answer:

$120

Step-by-step explanation:

First add the 10% back, to do so make it a decimal by moving the . over to the left twice.

Now setup the equation OP= New price/(1-discount)

91.80/(1-.10)=102

So the price before the 10% discount is $102

Now set it up again with the new numbers.

102/(1-.15)=120

So the original price before all discounts was $120

*Let p = original price

So firstly, how would we get the price when it's 15% off? You would find multiply the price by 0.15 (15% in decimal form) and then subtract the product from the original price. This can be represented as [tex](p-p\times0.15)[/tex]

Next, we would have to use the 10% off when the dress is already 15% off. The process is similar: Multiply 0.10 (10% in decimal form) with 15% off dress, then subtract the product from the 15% off price. This can be represented as [tex](p-p\times0.15)-0.10(p-p\times0.15)[/tex]

Now since the price is equal to $91.80, we would equal the prior expression to 91.80 as such: [tex](p-p\times0.15)-0.10(p-p\times0.15)=91.80[/tex] From here we can solve for p.

Firstly, solve the multiplication inside of the parentheses:

[tex](p-0.15p)-0.10(p-0.15p)=91.80[/tex]

Next, distribute -0.10 to (p - 0.15p):

[tex]p-0.15p-0.10p+0.015p=91.80[/tex]

Next, combine like terms:

[tex]0.765p=91.80[/tex]

Lastly, divide both sides by 0.765:

[tex]p=120[/tex]

The original price of the dress was $120.

(x+5)(x-5)(x+5i)(x-5i)

The factor of the expression x⁴ + 10x² + 25 is (x + √5i)(x - √5i) after using the factor method.

It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.

It is given that:

The expression is:

= x⁴ + 10x² + 25

Let t = x²

= t² + 10t + 25

= (t + 5)²

= (x² + 5)²

x² = -5

x = ±√5i

(x + √5i)(x - √5i)

Thus, the factor of the expression x⁴ + 10x² + 25 is (x + √5i)(x - √5i) after using the factor method.

Answer:

10 years.

Step-by-step explanation:

Let Jerome, Keenan, and Leitha have ages of x,y and z respectively,.

Then given that x+y =18  ... i

                           x+z =19  ... ii

                           y+z = 21 ... iii

From the above information we are to find out y and i.e.Keenan age.

Add all the 3 equations

Left side becomes x+y+y+z+z+x = 2(x+y+z)

and right side becomes = 18+19+21 = 58

In other words, 2(x+y+z) = 58

Divide by 2

x+y+z =29  ... iv

From the equation iv subtract ii

x+z =19

We get y = 10

Hence Kennan age = 10 years

Choice A: x^2−2x+4− 15/x+2

Step-by-step explanation:

The result of the division of the cubic polynomial x^3-7 by the binomial [tex]x+2 is x^2-2x+4 - 15/(x+2)[/tex], as obtained by carrying out the process of polynomial division.

The student is asking for the result of dividing a cubic polynomial, x^3-7, by a binomial, x+2. To do this, we need to perform polynomial division. The result of this division is [tex]x^2-2x+4 - 15/(x+2)[/tex]. We get this by setting up and performing the division, which operates similarly to long division, except that you are working with polynomials instead of numbers. The steps involved are too complicated to list here, but involve repeatedly subtracting multiples of x+2 from x^3-7 until the remainder is less than x+2, at which point you can't subtract more multiples of x+2.
