Step-by-step explanation:

Since we know they are similar triangles

8                15

---------- = -----------  

120              bridge


Using cross products

8 * bridge = 15* 120

8* bridge = 1800

Divide each side by 8

8/8* bridge = 1800/8

bridge = 225

Answer 2

Answer:

225m

Step-by-step explanation:

the 2 triangles shown are similar by AAA

so their sides are in the same ratio

bridge/15 = 120/8

What is a expression? What is a mathematical equation? What is Equation Modelling?

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Nate and Laura picked apples. Laura picked 1/2 as many as Nate picked. Together they picked 90 apples.

Let [n] stand for the number Nate picked. Then, the number of apples picked up by Laura will be (1/2)n. Then, we can write -

Equation : (1/2)n + n = 90

1.5n = 90

n = (90/1.5)

n = 60

Apples picked up by Nate : 60

Apples picked up Laura : 60/2 = 30

Therefore, the answers to all the parts are -

Equation : (1/2)n + n = 90

Apples picked up by Nate : 60

Apples picked up Laura : = 30

Compare the graph of g(x) =x^2 +6 with the graph of f(x)=x^2

Answers

Answer:


Step-by-step explanation:

If you know what g(x) looks like, you can find f(x). Every y point of g(x) is f(x) + 6.

The general point of g(x) is (x,f(x) + 6). That is the major difference. Just so you can see it visually, the both graphs are shown below.

red: f(x) = x^2

blue: f(x) = f(x) + 6 = x^2 + 6

green: x = 2  With the two points shown that intercept the two given functions.

Purple(?): x = - 2 with the two points shown that intercept the two given functions.

Final answer:

The graphs of both g(x) =x² +6 and f(x)=x² are parabolas. However, while the vertex of the graph of f(x) = x^2 is at the origin, the graph of g(x) = x² + 6 is shifted upwards by six units, with the vertex of g(x) at (0,6). The shape of the two graphs is identical.

Explanation:

The graphs of g(x) =x² +6 and f(x)=x² are both parabolas, but their positions differ on the coordinate plane. The function f(x) = x² is a standard quadratic function with a vertex at the origin (0,0). On the other hand, g(x) = x² + 6 is a vertical translation of the graph of f(x) = x2 upwards by six units. So, the vertex of g(x) is at the position (0, 6). Furthermore, the shape of the two graphs will remain the same as they both have the same degree and leading coefficient.

how many meters are in 5 millimeters are in 2 kilometers?

Answers

Answer:

5 mililmiters = 0,005 meters = 0,000005 kilometers

2 kilometers = 2000 meters

Step-by-step explanation:

km  / hectometer / decameter / meter / dcm / centimeter / milimeter

1000 m /     100  m   /    10   m     <     1  >    0,1 m/    0,01  m     /  0,0001 m

1 meter = 0,  1 decimeters / 0, 01 centimeters /0, 000 1 millimeters

1 meter = 10 decameters / 100 hectometers / 1000 kilometers


so 5 millimeters = 0,005 meters = 0, 000 005 kilometers

The lines below are perpendicular. If the slope of the green line is -3 what is the slope of the red line?

Answers

Answer:

1/3

Step-by-step explanation:

Given that two lines are perpendicular.

Slope of green line (one of the lines) is -3.  

To find the slope of other perpendicular line red.

We know that angle between two lines with slopes m1 and m2 would be

[tex]tan^{-1} \frac{m1-m2}{1+m1m2}[/tex]

where m1 is the slope of I line and m2 slope of second line.

Here since two lines are perpendicular angle between them is 90 degrees and hence we get infinity as tan x

this implies denominator for [tex] \frac{m1-m2}{1+m1m2}[/tex]=0

i.e. 1+m1m2 = 0

Or m1m2 =-1

Since one of slope m1 = -3 we have

-3m2= (-1) or m2 = 1/3

Answers

Substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12    use distributive property

x + (2)(2x) + (2)(-4) = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20    divide both sides by 5

x = 4

Put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

Answer: x = 4 and y = 4

Answer:

x=4, y=4

Step-by-step explanation:

y=2x-4;

x+2y=12

We can use substitution since the first equation is solved for y

Where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

Distribute the 2

x+4x-8 = 12

Combine like terms

5x-8=12

Add 8 to each side

5x-8+8=12+8

5x=20

Divide by 5

5x/5 = 20/5

x =4

The area of a trapezoid is given by the formula A = 1 2 h(B + b). Solved for b, this formula becomes b =

Answers

Answer:b = (2A - hB)/h


Step-by-step explanation:

See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.

Here B and b are parallel sides which we know by comparing the equation.

And 'h' here is the perpendicular distance between parallel sides.

We have to write the equation in terms of one of the parallel sides 'b'

Our formula is A = 1/2*h*(B+b)

I.e. 2A = h*(B+b) (Multiplying both sides by 2)

I.e. 2A - hB = hb

I.e. b = (2A - hB)/h

Pink is shoe is 20.4 cm long Rajesh shoe is 7 mm longer than pinky shoe how long is Rajesh shoe in cm

Answers

Rajesh shoe is 21.1 cm
Final answer:

To find the length of Rajesh's shoe, convert the additional length from millimeters to centimeters and add it to Pinky's shoe length. Rajesh's shoe is 21.1 cm long.

Explanation:

The subject of this question is Mathematics and it is suitable for a Middle School student. To find the length of Rajesh's shoe, we need to add the length of Pinky's shoe to the additional length that Rajesh's shoe has. Pinky's shoe is 20.4 cm long, and Rajesh's shoe is 7 mm longer.

Firstly, we need to convert millimeters to centimeters since 1 cm equals 10 mm. Therefore, 7 mm is equivalent to 0.7 cm (since 7 divided by 10 equals 0.7).

Next, we add this length to Pinky's shoe length:

20.4 cm (Pinky's shoe length)+ 0.7 cm (additional length)

Rajesh's shoe length equals 21.1 cm.

We can find the slope using

m = (y2-y1)/(x2-x1)

 = (-7--1)/(-5-0)

 = (-7+1)/(-5-0)

 = -6/-5

 = 6/5

We also have the y intercept ( when x=0)  It is -1

We can use the slope intercept form of the equation y = mx+b

y = 6/5 x-1

Depending on what you mean when you say simplify your answer

We can put it in standard form  ax+by = C

Multiply both sides by 5

5y =5* 6/5 x-1*5

5y = 6x-5

Subtract 6x from each side

-6x+5y = 6x-6x-5

-6x+5y = -5

Multiply by -1

When 2x^2 - 20x + 49 = 19 is written in the form (x - p)^2 = q, what is the value of q? Show your work please.

Answers

Answer:

  q = 10

Step-by-step explanation:

The desired form is a rearrangement of the given equation, divided by the leading coefficient.

Monic polynomial

A monic polynomial is one with a leading coefficient of 1. The desired form requires that we start from that condition. In order to avoid fractions, we can begin by subtracting the constant term on the left.

  2x^2 -20x +49 = 19 . . . . . . given

  2x^2 -20x = -30 . . . . . . . . subtract 49

  x^2 -10x = -15 . . . . . . . . . divide by 2

Completing the square

The square of the binomial a+b is given by ...

  (x +b)^2 = x^2 +2bx +b^2

That is the constant term on the right is the square of half the coefficient of x. To achieve this perfect square trinomial in our equation, we need to add the square of half of -10.

  x^2 -10x +25 = -15 +25 . . . . . . add (-10/2)^2 = 25 to both sides

  (x -5)^2 = 10 . . . . . . . . . . . write in the desired form

The height of the water in an a over ground pool is 3ft. As the number of water drains ,the rate of -1/2 inch per minute. Write and solve an equation to find how many minutes it will take to drain the pool

Answers

Answer:

36 - 1/2x = 0

72 minutes

Step-by-step explanation:

there is a total of 3 feet in the pool at the start, 1 ft = 12 in, and 3 ft = 36 in. the pool is losing water, so we have to subtract. it is losing water at a rate of -1/2 in per minute, and we don't know how many minutes it will take

we have to set it equal to 0 because we are trying to find out how long it will be until the pool is completely drained, which is when there will be no water left, so it will be 0

subtract 36 from both sides

-1/2x = -36

divide both sides by -1/2

x = 72

Work out the density of the drink. Give your answer correct to 3 decimal places.

Answers

Answer:

Density = 1.042  grams /cm^3

Step-by-step explanation:

Work out the mass of each of three in a unit volume (cm^3)

Givens

Apple Juice = 1.04 grams / cm^3Fruit Syrup = 1.6 grams / cm^3Sparkling water = 0.99 grams / cm^3

Mixture

35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams

25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 =                  40    grams

270 cm^3 water = 0.99 * 270                                        267.3 grams

Total Mixture

Volume = 25 + 35 + 270 = 330 cm^3Mass =  36.4 + 40 + 267.3 = 343.7 grams

Density

Density = mass / volume = 343.7 / 330 = 1.0415

Answer

1.042 grams / cm^3  

The density of the resulting drink is; 1.042 grams per cm³.

To find the density of the resulting drink, we need to first determine the mass of each of the constituents.

The masses of the constituents can be found as follows;

Mass = density × volume

For apple juice;

Mass(a) = 1.04 × 35 = 36.4grams

For fruit syrup;

Mass(f) = 1.6 × 25 = 40grams.

For sparkling water;

Mass(s) = 0.99 × 270 = 267.3grams

Therefore, the total mass of the drink is;

= 36.4 + 40 + 267.3 = 343.7 grams.

And, since the total volume of the drink is 330cm³

Density of the drink = 343.7 grams/ 330 cm³

Density of the drink = 1.042 grams per cm³.

what is the 20th term of the arithmetic sequence 8,21,34,47,60,..

Answers

Well considering that

F (1) = 8

F (x) = f(x-1) + 13


(Meaning the previous term plus 13)


So

F (x) = 13x - 5


F (0) = -5


Final answer:

The 20th term of the given arithmetic sequence 8, 21, 34, 47, 60... is 255.

Explanation:

In the field of mathematics, this type of problem is referred to as an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. This difference is called the common difference.

In your question, the arithmetic sequence provided is 8, 21, 34, 47, 60... Here, the common difference is 13 (i.e., every term after the first is 13 more than the preceding term).

To find any term (let's say the nth term) in an arithmetic sequence, you can use the formula:

nth term = first term + (n - 1) * common difference

Applying this formula to find the 20th term:

20th term = 8 + (20 - 1) * 13 = 8 + 247 = 255
