Answer:

1. x= 20/3 or 6.6666 repeating

2. x=3

3. a=39

Step-by-step explanation:

1. subtract 25 by 5 to get 20, then divide 20 by 3 to get x

2. divide 7 by 21 to get x

3. add 8 to 31 to get a equals 39

Answer:

x = 6.6 repeating 7

Step-by-step explanation:

subtract 5 on both sides

ur left with 3x = 20

divide by 3 on both sides

Answer:

Granddaughter = 8

Grandfather = 72

Step-by-step explanation:

Let :

Granddaughter's age = x

Grandfather's age = y

y = 9x

Age in 8 years :

Granddaughter's age = x + 8

Grandfather's age :

y + 8 = 5(x + 8)

y = 9x

Then ;

9x + 8 = 5(x + 8)

9x + 8 = 5x + 40

9x - 5x = 40 - 8

4x = 32

x = 32 / 4

x = 8

y = 9x = 9*8 = 72

Respuesta:

960 m

Explicación paso a paso:

Paso 1: Información provista

Superficie del parque (S): 1600 m²

Paso 2: Calcular cuanto mide cada lado (l) del parque

El parque es un cuadrado, por lo que podemos encontrar la longitud del lado usando la siguiente fórmula.

S = l²

l = √S = √1600 m² = 40 m

Paso 3: Calcular el perímetro del parque (P)

El perímetro es la cantidad de metros que reccorre cuando da una vuelta completa.

P = 4 l = 4 × 40 m = 160 m

Paso 4: Calcular la distancia recorrida cuando corre 6 vueltas

Debemos multiplicar el perímetro por 6.

6 × 160 m = 960 m

Answer: 0.1334

Step-by-step explanation:

Given

There are seven trails with a probability of success is  [tex]p=\frac{1}{4}[/tex]

[tex]\therefore q=1-p\\q=1-\frac{1}{4}\\q=\frac{3}{4}[/tex]

Using the binomial distribution, the Probability of exactly no success i.e. x=0 is given by

[tex]\Rightarrow ^7C_0\cdot p^0 \cdot q^{7-0}\\\Rightarrow 1\times(\frac{1}{4})^0 \cdot (\frac{3}{4})^7\\\Rightarrow 1\times 1 \cdot (0.75)^7\\\Rightarrow 0.1334[/tex]

Answer:

c. y = 3sin(x+ 3) - 2

Step-by-step explanation:

good luck

The function whose graph is given by y= 3 sin (x+3) - 2

An phrase, rule, or law that establishes the link between an independent variable and a dependent variable is known as an unction in mathematics. In mathematics, functions exist everywhere, and they are crucial for constructing physical links in the sciences.

From the graph we can see that

When x= 1 then f(x) = -4.

Now, putting the value in functions as

1. y= 5 sin (x-3)-2

When x= 1 then

y= 5 sin (-2)- 2

y= -2.17

So, function not satisfied.

2. y= 3 sin (x+3) + 2

When x= 1 then

y= 3 sin (4)+ 2

y= 2.20

So, function is not satisfied.

3. y= 3 sin (x+3) - 2

When x= 1 then

y= 3 sin (4)- 2

y= -3.79

So, function is satisfied.

Answer:

22.5°

Step-by-step explanation:

The sum of the interior and exterior angles of a regular polygon is 180°

ext + int = 180°

7 int + int = 180°

8 int = 180° ( divide both sides by 8 )

int = 22.5°

a=29

Step-by-step explanation:

If a=b and b is 25

Then a is 25

25+24=49

Answer:

I believe the answer is 49. This is because if B = 25 and A = B, therefore, A = 25 and 25 + 24 = 49.

Answer:

92.18 feet

Step-by-step explanation:

t(n)=125(.97)^x

t(10)=124(.97)^10

Sequence cant have partial or discrete bounce

Answer:

92.18 ft

Step-by-step explanation:

The rebound ratio 0.97 means the ball will rebound 97% of its height on the previous bounce.

Bounce    Height

1                125(0.97) = 121.25

2               125(0.97)(0.97) = 117.6125

3               125(0.97)(0.97)(0.97) = 114.084125

See a pattern?

Bounce     Height

1                125(0.97)

2               125(0.97)^2

3               125(0.97)^3    the exponent matches the bounce number

Tenth bounce:

10             125(0.97)^10 = 92.18 (rounded to 2 places)

The translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' will be; (d) T2, 1(x, y)

Given that the parallelogram ABCD is shifted to the right by 2 units and shifted up by 1 unit to get parallelogram A'B'C'D'

This transformation rule is represented as given;

(x,y) -> (x + 2,y + 1)

This transformation rule can be rewritten

T2, 1(x, y)

Hence, the translation from the pre-image, Parallelogram ABCD, to the image, Parallelogram A'B'C'D' would be;

(d) T2, 1(x, y)

on C 1 ice cream cost $1.2 if you multiply 1.2x12=14.4

THE CORRECT ANSWER IS...

C ($9.59 for 8 scoops)

Step-by-step explanation:

well, if you divided 14.89 by 12 it equals $1.24. so that means it's $1.24 for one single scoop for that one. then for B if you divided $7.99 by 5, you'd get $1.60, so that's $1.60 per scoop for B. lastly $9.59 divided by 8 is $1.20, which is the lowest price per scoop, so that makes it the best and most affordable one. i hope i explained that easily, but basically all in all, the answer is C.

The correct answer is in BOLD.

1.24 (A)

1.60 (B)

1.20 (C)
