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

Does this help?

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

6(x + 8) = 5(x-4)

Use the distributive property:

6x + 48 = 5x -20

Subtract 48 from both sides:

6x = 5x - 68

Subtract 5x from both sides

X = -68

Answer: D. -68

Answer: C: object 1 is moving, and object 2 is not moving

Step-by-step explanation since object one is on unbalanced forces, it can cause it to start moving (ex: a hill, if a skateboard is sitting on the top of a hill on unbalanced forces it will probably roll down.) but since object 2 is on balanced forces it wont start to move and/or roll forwards or anything like that.

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

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:

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:

24

Step-by-step explanation:

Answer:

h = 24 cm

Step-by-step explanation:

Area = 1/2 b * h

b = 5 cm

Area = 60 cm^2

60 = 1/2 * 5 * h                   Multiply both sides by 2

60*2 = 2*1/2 *  5 * h            

120 = 5 h                           Divide by 5

24 = h

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)

Answer:

Option A

Step-by-step explanation:

Answer:

B

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

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
