Calculate the rise and run to find the slope of the line

Answer:

Step-by-step explanation:

We translate Grayson's charges through the following mathematical expression : 35 h + 35 where h is the number of hours while that of Ian is 45h + 15. The number of hours where the charges are equal is 35h + 35 = 45h + 15; h = 2 hrs. Hence the number of hours minimum must be above 2 hours.

Probabilities are used to determine the chances of events

(a) Coins

In a coin, the probability of the likely outcomes in each flip are:

Head = 1/2

Tail = 1/2

So, the probability that the first lands on head, while the second lands on tail is:

[tex]\mathbf{Pr = \frac 12 \times \frac 12}[/tex]

[tex]\mathbf{Pr = \frac 14}[/tex]

The probability that the first lands on head, while the second lands on tail is 1/4

(b) Deck of cards

There are 52 cards in a deck, 13 of which are hearts while 4 are jack.

The probability that the first card is heart is 13/52

The probability that the second card is jack is 4/51

So, the probability that the first selected card is heart, while the second is jack is:

[tex]\mathbf{Pr = \frac{13}{52} \times \frac{4}{51}}[/tex]

[tex]\mathbf{Pr = \frac{1}{51}}[/tex]

The probability that the first selected card is heart, while the second is jack is 1/51

(c) Digits and Letters

There are 10 digits between 0 and 9, so the probability of selecting 3 is 1/10.

There are 21 consonants, so the probability of selecting a consonant is 21/26

So, the probability of selecting 3 and a consonant is:

[tex]\mathbf{Pr = \frac{1}{10} \times \frac{21}{26}}[/tex]

[tex]\mathbf{Pr = \frac{21}{260}}[/tex]

The probability of selecting 3 and a consonant is 21/260

(d) Dice

There are 3 even numbers on a die; so the probability of landing on an even number is 3/6

There are 2 numbers less than 3 on a die; so the probability of landing on a number less than 3 is 2/6

So, the probability of landing on an even number and a number less than 3 is:

[tex]\mathbf{Pr = \frac 36 \times \frac 26}[/tex]

[tex]\mathbf{Pr = \frac 16}[/tex]

The probability of landing on an even number and a number less than 3 is 1/6

Answer:

x²-6x+y²-4y=-4

Step-by-step explanation:

We know the circle equation stands like this:

(x-a)² + (y-b)² = R²

and (a,b) is center

and R stands for Radius

so in this case:

center = (3,2)

R = 3

So

(x-3)² + (y-2)² = 9

x²-6x+9 + y²-4y+4=9

x²-6x+y²-4y=-4

Answer:

14

Step-by-step explanation:

This can be seen as a arithmetic series. It is the number of girls, let’s say g, plus the number of girls plus five boys. Deena, can be viewed as 1, plus 5 equals 6. Then Chloe, 2, plus 5 equals 7. And so on and on.

We can create an equation for this:

g+(g+5)=s

(s is the number of students.)

‘If the total number of students is 23;

g+(g+5)=23

We can solve this for:

2g = 23-5 ⇒

g=9

So the number of girls is 9, th number of boys is simply:

23-9=14

Step-by-step explanation:

I can't conveniently copy the logical symbols you use, so I write

AND = ∧ (conjunction)

OR = ∨ (disjunction)

NOT = ¬

Tautologically,

p = (p AND q) OR (p AND NOT q)

and we can distribute the OR to get the equivalent statement

(p OR (p AND NOT q)) AND (q OR (p AND NOT q))

and again to get

((p OR p) AND (p OR NOT q)) AND ((p OR q) AND (q OR NOT q))

Now, q OR NOT q is always true, and p OR p is simply p, so we have

p = p AND (p OR q) AND (p OR NOT q)

This shows that p OR NOT q is already included in p, so our initial statement is simply

p AND (NOT p OR NOT q)

Distributing the conjunction, we get

(p AND NOT p) OR (p AND NOT q)

p AND NOT p is tautologically false, but we're considering a disjunction, so the truth value of p AND NOT q is the only value that's relevant. So, the initial statement collapses to

p AND NOT q

My understanding of rational numbers will be A. I can explain what rational and irrational numbers are, and I can identify them. I can use rational numbers to estimate the value of an irrational number.

It should be noted that rational numbers are the numbers that are expressed as the ratio of two integers.

It should be noted that they can be fractions, integers, decimals,etc. Examples include 5, 3.7, 1/5, etc.

A rational number is one that can be written as the ratio or fraction p/q of two numbers, where p and q are the numerator and denominator, respectively. For instance, every integer and 3/7 are rational numbers.

A real number that cannot be expressed as a straightforward fraction is referred to as an irrational number. It cannot be described using a ratio. When p and q are integers and q is not equal to 0, N is not equal to p/q if N is irrational.

Answer:

12 apples

Step-by-step explanation:

5 apples = 0.6kg

1 apple = 0.12kg

x = 0.6kg x 2

= 1.2kg (10 apples)

y = 1.44kg - 1.2kg

= 0.24kg (2 apples)

Apples = x + y

= 10 + 2 apples

= 12 apples (weigh 1.44kg)

The triangles would not be congruent since it was dilated.

Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.

Rigid transformation are transformation that preserve the shape and size of the figure. These are rotation, reflection, and translation. Dilation is not a rigid transformation because it reduces or increases the size of the figure.

Two triangles are congruent if they have the same shape and size.

Answer:

Step-by-step explanation:

let x be the length of one base in mm

The other base will be 2x - 7 mm

I will ASSUME you mean the area is 48 mm²

Area of a trapezoid is the Average base length times height

A = ½(x + (2x - 7))h

A = ½(3x - 7)h

2A/h = 3x - 7

2A/h + 7 = 3x

x = (2A/h + 7)/3

x = 2A/3h + 7/3

x = 2(48)/3(12) + 7/3

x = 5 mm

the other length is

2(5) - 7 = 3 mm

Answer:

8500m

Step-by-step explanation:

t = 15 + 0.01 h

t = 100 (given in the question)

∴ 100 = 15 + 0.01 h

   100 - 15 = 0.01 h

   85 = 0.01 h

   85 / 0.01 = h

   8500 / 1 = h

  8500 = h

Answer:

Circumference ≈ 82.9

Step-by-step explanation:

The formula for calculating the circumference of a circle is:

C = 2πr

Where 3.14 is pi (as stated on your screen)

And r is the radius.

Knowing this substitute those values

C = 2(3.14)(13.2)

Multiply 2 and 3.14.

C = (6.28)(13.2)

Multiply 6.28 and 13.2.

C = 82.9 when rounded.
