Answer:

Answer : Gina's age is 19 years.

Step-by-step explanation:

Kamal is 17 years older than Gina. Gina is 3 years younger than Rachelle.

Let Gina's age be x years

So Kamal’s age will be = x + 17

Rachelle’s age = x + 3

the sum of their ages is 77, Accordingly

x + x + 17 + x + 3 = 77

3x + 20 = 77

3x = 77 - 20

3x = 57

x = 57/3

x = 19

Thus Gina's age is 19 years,

Kamal’s age x + 17 = 19 + 17 = 36 years

Rachelle’s age x + 3 = 19 + 3 = 22 years

Gina = 19 years old

Answer: [tex]d=\dfrac{t}{15}[/tex], where d= distance that Kiran walks in t minutes.

Step-by-step explanation:

Given: Kiran walked at a constant speed.

He walked 1 mile in 15 minutes.

The, distance walked by Kiran in 1 minute = [tex]\dfrac1{15}[/tex] mile

The distance that Kiran walks in t minutes = [tex]t\times\dfrac{1}{15}[/tex] miles

If d= distance that Kiran walks in t minutes

The required equation: [tex]d=\dfrac{t}{15}[/tex]

Answer:

x = 19°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus

x + 106° = 125° ( subtract 106° from both sides )

x = 19°

Answer:

The value of [tex]r=33[/tex] which makes the equation true.

Step-by-step explanation:

Given the equation

[tex]\frac{r}{-11}=-3[/tex]

We have to find the value of r for which the equation must be true.

solving the equation

[tex]\frac{r}{-11}=-3[/tex]

Multiply both sides by -11

[tex]\frac{r\left(-11\right)}{-11}=\left(-3\right)\left(-11\right)[/tex]

[tex]r=33[/tex]

Therefore, the value of [tex]r=33[/tex] which makes the equation true.

VERIFICATION:

Putting [tex]r=33[/tex] in the equation

[tex]\frac{r}{-11}=-3[/tex]

[tex]\frac{33}{-11}=-3[/tex]

[tex]-3=-3[/tex]              ∵ [tex]\frac{33}{-11}=-3[/tex]

L.H.S = R.H.S

Therefore, the value of [tex]r=33[/tex] which makes the equation true.

The slope would be 4.

The Y-intercept is 2.

Answer:

F. [tex] 4, 4\sqrt{3} [/tex]

Step-by-step explanation:

✔️Finding length of side s using:

[tex] cos(\theta) = \frac{adjacent}{hypotenuse} [/tex]

Where,

[tex] cos(\theta) = cos(60) = \frac{1}{2} [/tex]

Adjacent = s

Hypotenuse = 8

Plug in the values

[tex] \frac{1}{2} = \frac{s}{8} [/tex]

Multiply both sides by 8

[tex] \frac{1}{2} \times 8 = \frac{s}{8} \time 8 [/tex]

[tex] \frac{8}{2} = s [/tex]

[tex] 4 = s [/tex]

s = 4

✔️Finding length of side q using:

[tex] sin(\theta) = \frac{opposite}{hypotenuse} [/tex]

Where,

[tex] sin(\theta) = sin(60) = \frac{\sqrt{3}}{2} [/tex]

Opposite = q

Hypotenuse = 8

Plug in the values

[tex] \frac{\sqrt{3}}{2} = \frac{q}{8} [/tex]

Multiply both sides by 8

[tex] \frac{\sqrt{3}}{2} \times 8 = \frac{q}{8} \times 8 [/tex]

[tex] \frac{\sqrt{3}}{1} \times 4 = q [/tex]

[tex] 4\sqrt{3} = q [/tex]

[tex] q = 4\sqrt{3} [/tex]

Answer:

The dryer cost $375

Step-by-step explanation:

834/2 = 417

84/2 = 42

417 - 42 = 375

834 - 375 = 459

459 - 84 = 375

PROOF: 417 - 375 = 42 then double that answer to get 84

Answer:

a8 = 512.

Step-by-step explanation:

This is geometric sequence with common ratio r = 2 and first term a1 = 4.

nth term = a1 r^(n-1)

So a8 = 4 2(^8-1)

= 4 * 2^7

= 4*128 = 512.

Answer:

Length = 6.25 feet

Step-by-step explanation:

Your dad is designing a new garden for your backyard. He has 20 feet of fencing to go around the garden.

Let the width is x.

Length is 2 1/2 feet longer than the width i.e. (x+2 1/2) = (x+2.5) feet

Perimeter = 20 feet

2(l+b) = 20

(l+b) = 10

(x+2.5+x) = 10

2x+2.5 = 10

2x = 7.5

x = 3.75 feet

Length = (x+2.5)

= (3.75+2.5)

= 6.25 feet

So, the length of the garden is 6.25 feet.

Answer:

A = 25.758 m²

Step-by-step explanation:

Width of the sand pit, b = 2.7 m

Length of the sand pit, l = 9.54 m

We want to cover the sand pit with a piece of plastic. We need to find how many square meters of plastic will be needed to cover the sand pit. It is equal to the area of sand pit. It is in the shape of rectangle. Its area is given by :

A = l × b

A = 2.7 × 9.54

A = 25.758 m²

So, 25.758 m² of plastic will be needed to cover the sand pit.

Answer:

X = -4Y/9 + 32/3

Step-by-step explanation:

you can solve for X by simplifying both sides of the equation then isolating the variable

The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.

A formula known as an equation uses the same sign to denote the equality of two expressions.

In another word, the equation must be constrained with some constraints.

Given the equation,

y = -9/4(x - 8) + 6

By taking LCM in right-hand side

y = [-9(x - 8) + 24]/4

Cross multiply

4y = -9(x - 8) + 24

Interchange

9(x - 8) = 24 - 4y

9x - 72 = 24 - 4y

x = (4/9)y + 96/9

Hence "The value of the given equation y = -9/4(x - 8) + 6 for the x will be x = -(4/9)y + 96/9".

Answer:

Step-by-step explanation:

First, find the cost of both pairs of sunglasses after the discounts

65% = 65/100 = 0.65

($48)(0.65) = $31.20

55% = 55/100 = 0.55

($38)(0.55) = $20.90

Then subtract the bigger cost (31.20) from the smaller cost (20.90)

$31.20 - $20.90 = $10.30

$10.30 is your price difference.
