Answer:

x = 6

y = 4

Step-by-step explanation:

-x + 3y = 6 → times (-1)

x + 3y = 18

x - 3y = -6

x + 3y = 18

________ -

__-6y = -24

___y = -24/-6

___y = 4

x - 3y = -6

x - 3(4) = -6

x - 12 = -6

x = -6 + 12

x = 6

Answer:

x = 6, y = 4

Step-by-step explanation:

-x + 3y = 6  

x + 3y = 18

If you are looking for x and y it is...

x = 6

Answer: b. Damarias median sale is $52

Step-by-step explanation:

Hi, the correct option is b. Damarias median sale is $52.

If we rank the sales order from lowest to highest

28 46 48 48 52 52 59 60 71 192

Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

Answer: a) 70 mph

b) 80 mph

Step-by-step explanation:

Given that Kayleen left home at noon and drove to boston.she got there at 4:00. Then time spent will be 4 hours . Noon means 12pm

Distance covered = 280 miles kayleens average speed will be

Speed = distance/time

Speed = 280/4 = 70 mph

Given that Elijah was already 40 miles closer than Kayleen was when she started

Distance covered by Elijah will be

Distance = 40 + 280 = 320

Time = 4 hours

Speed = 320/4 = 80 mph

Answer:

would go for C, SSS (side side side theorem)

Jenny's future age would be expressed as ((x+4)/(2x+4))*100 percent of Benny's future age, where x is Jenny's current age.

To solve this problem, we first note that Benny is currently 200% of Jenny's age, meaning Benny's age is twice that of Jenny. So let's denote Jenny's current age as x - Benny's age will be 2x.

In 4 years, Jenny's age will be x+4 and Benny's age will be 2x+4. To calculate what percent of Benny's future age will Jenny's future age be, we have to divide Jenny's future age (x+4) by Benny's future age (2x+4) and then multiply by 100 to get the percentage. Therefore, Jenny's age will be ((x+4)/(2x+4))*100 percent of Benny's age.

Since we don't know their real ages, this is the most accurate answer we can provide, expressed as an algebraic equation. In real-life situation with the real ages known this equation would allow to find out what percent of Benny's age will Jenny’s age be in 4 years.

If Jenny's age is x, Benny's age is 2x. In 4 years, Jenny's age will be x+4 and Benny's will be 2x+4. To calculate what percent of Benny's age Jenny's age will be, we can use this formula: ((x+4)/(2x+4)) × 100.

Let's start by expressing Benny's age in terms of Jenny's age. If Benny's age is currently 200% of Jenny's age, then mathematically, we can say:

Benny's age = 200% of Jenny's age

B = 2 × x

Now, let's assume Jenny's age is represented as J. So, Benny's age is 2 × x.

If we want to find out what percent of Benny's age Jenny's age will be in 4 years, let's calculate it step by step.

In 4 years, Benny's age will be:

Benny's age in 4 years = Benny's current age + 4

Benny's age in 4 years = 2 × x + 4

Jenny's age in 4 years will be:

Jenny's age in 4 years = Jenny's current age + 4

Jenny's age in 4 years = x + 4

Now, let's find out what percent of Benny's age Jenny's age in 4 years will be:

Percent = (Jenny's age in 4 years / Benny's age in 4 years) × 100

Percent = (x + 4) / (2 × x + 4) × 100

This calculation will give us the percentage of Jenny's age compared to Benny's age in 4 years.

the correct answer is

D. 80 ft^3

vol. of pyramid = (l× w × h)/3

= (6×8×5)/3

= 80 ft^3

Answer:

Step-by-step explanation:

Answer:

3.32ft

Step-by-step explanation:

The wire and the poles attached to the ground form a right triangle with the length of the wire being the hypotenuse.

Using Pythagoras Theorem:

Hypotenuse²=Adjacent²+Opposite²

6²=5²+x²

x²=36-25

x²=11

x=√11=3.32 ft.

The wires are attached 3.32 ft from the base of the pole on the ground

Answer:

The question can be answered by using a Pythagoras' Theorem :  [tex]c^2=a^2+b^2[/tex] to find the base of  the pole to which each wire is  attached to the ground.

Step-by-step explanation:

the base of the pole is represented by b.

the height of the pole is represented by a= 5 feet

the length of t he wire is represented by c=5 feet.

Thus, using the Phytagoras Theorem,

c^2=a^2+b^2,

[tex]6^2=5^2+b^2\\36=25+b^2,\\36-25=b^2\\Thus, b^2=11,\\b=\sqrt 11[/tex] or b=3.3.

Thus , each wire i attached by about 3.3 feet to the base of the pole.

Answer:

c) 20,000

Step-by-step explanation:

Number of digits = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 = 10,

Number of vowel letters = a, e, i, o, u = 5

Repetition of digits is permitted but repetition of vowel letters is not permitted

Let the password be presented in dash form as shown below:

____ ____ ____ ____ ____ =

  D       D       D       V       V

where:

D = possible number of digits to fill the spot

V = possible number of vowels to fill the spot

Since repetition of digits is permitted, each spot marked as D can be filled with any one of 10 digits from 0 - 9

The first spot marked V has 5 possible options (a, e, i, o, u) & the second spot marked V only has 4 possible options (since repetition of vowels is not permitted).

We then place the number of possibilities in each spot and multiply them to determine the number of passwords possible

10  *  10  *  10  *  5  *  4 = 20,000

Therefore, the number of possible passwords is 20,000

Answer:

EM = 73 m

Step-by-step explanation:

Using the right triangle MOE

with legs MO = 48. EO = 55 and hypotenuse EM

Applying Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

EM² = 48² + 55² = 2304 + 3025 = 5329 ( take the square root of both sides )

EM = [tex]\sqrt{5329}[/tex] = 73

Given that the height of the cone is 12 ft.

The volume of the cone is 90 ft³

We need to determine the area of the base of the cone.

Area of the base of the cone:

The area of the base of the cone can be determined using the formula,

[tex]V=\frac{1}{3} \pi r^2 h[/tex]

where the base area is [tex]A=\pi r^2[/tex]

Substituting the value of A in the above formula, we get,

[tex]V=\frac{1}{3}A h[/tex]

Substituting V = 90 and h = 12, we get;

[tex]90=\frac{1}{3}A (12)[/tex]

[tex]90=4A[/tex]

Dividing both sides by 4, we get;

[tex]22.5 =A[/tex]

Thus, the area of the base of the cone is 22.5 square feet.

Hence, Option c is the correct answer.

Answer:

Step-by-step explanation:

The student needs to use the average rate of change formula correctly. For the function f(x) = 0.5x^2 and the interval [-4, -2], the correct average rate of change is -3.

The student is looking to find the average rate of change of the function f(x) = 0.5x^2 over the interval [-4,-2]. The average rate of change of a function over the interval [a, b] is calculated by the formula: (f(b) - f(a)) / (b - a).

For our function and interval this calculates to (f(-2) - f(-4)) / (-2 -(-4)). f(-2) is 0.5(-2)^2 = 2, and f(-4) is 0.5(-4)^2 = 8. Substituting into the formula gives (2 - 8) / (-2 -(-4)) = -6 / 2 = -3. So the correct average rate of change for f(x) = 0.5x^2 over the interval [-4,-2] is -3.

Answer:

d

Step-by-step explanation:

The correct answer is option C: 13 meters. Jacob and Sharon are approximately 13 meters apart.

To determine how far apart Jacob and Sharon are now, we first need to find their final positions and then calculate the distance between those points.

Step-by-Step Solution

→ Jacob's Movement:

He walked 3 meters north and then 4 meters west.

→ Final position of Jacob: (-4, 3).

Sharon's Movement:

→ She walked 5 meters south and then 12 meters east.

→ Final position of Sharon: (12, -5).

To find the distance between their final positions, we can use the Pythagorean theorem. The distance d between the points (-4, 3) and (12, -5) is calculated as follows:

→ d = √[(12 - (-4))² + (-5 - 3)²]

= √[(12 + 4)² + (-8)²]

= √[(16)² + (8)²]

= √[256 + 64]

= √320

= √(16 × 20)

= 4√20

= 4√(4 × 5)

= 8√5

≈ 13 meters

→ Thus, Jacob and Sharon are approximately 13 meters apart.
