Drag the ruler or protractor over a segment or an angle to get its measure. Check each pair of corresponding sides and each pair of corresponding angles for equal measures. If each pair is equal in measure, the triangles are congruent. If any one of the measures of a pair is not equal, the triangles are not congruent. Are these triangles congruent?.

Formula:

[tex] \frac{5000}{2000} [/tex]

[tex] = > \frac{5}{2} [/tex]

Hence, 5000 Pound is equal to 2.5 Ton.

Step-by-step explanation:

The unit of weight in the avoirdupois system equal to 2,000 pounds in the United States and 2,240 pounds in Britain. The metric ton used in most other countries is 1,000 kg, equivalent to 2,204.6 pounds.

Answer: 2 1/2

Step-by-step explanation:

Answer: m<XVY = 82°

Step-by-step explanation: The measure of an angle formed by two chords that intersect inside a circle is equal to half the sum of the measures of the intercepted arcs.

Since the measures of the intercepted arcs are 86° and 78°,

we can setup the equation m<XVY = 1/2(86 + 78).

So we get m<XVY = 1/2(164) or m<XVY = 82°

Answer:

4

Step-by-step explanation:

Exponential functions are written in the form  [tex]f(x)=ab^x[/tex]

[tex]a[/tex] is the initial value of an exponential function and is found by substituting [tex]x=0[/tex] into the function as [tex]b^0=1[/tex]

Therefore, as y = 4 when x = 0, the initial value is 4

Answer:

f(5) = 17

Step-by-step explanation:

Using the recursive rule and f(1) = 5 , then

f(2) = f(1) + 3 = 5 + 3 = 8

f(3) = f(2) + 3 = 8 + 3 = 11

f(4) = f(3) + 3 = 11 + 3 = 14

f(5) = f(4) + 3 = 14 + 3 = 17

Given, A + B = 90°

Putting values, we get

7x + 4 + 4x + 9 = 90°

11x + 13 = 90°

11x = 90 - 13 = 77°

x = 7°

Now, m<A = 7x + 4

= 7(7) + 4 = 53°

Hope this helps :)

Answer:

m∠A = 53°

Explanation:

complement angle: : two angles that add up to 90 degrees.

solve:

7x + 4 + 4x + 9 = 90

7x + 4x = 90 - 9 - 4

11x = 77

x = 7

Find m∠A:

7x + 4

7(7) + 4

49 + 4

53°

Answer:

First one
2x+3

Step-by-step explanation:

We can factorise the area:

6x²+9x-4x-6

3x(2x+3)-2(2x+3)

(3x-2)(2x+3)

So the width is 2x+3

Scale drawing takes scaled versions of original lengths. The actual length of the swing set area of the park is 25 ft long and 100 ft wide

For a particular scale drawing, it is already specified that all the measurements' some constant scaled version will be taken. For example, let the scale be K feet to s inches.

Then it means

[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]

All feet measurements will then be multiplied by s/k to get the drawing's corresponding lengths.

For the given case, it is given that

Real dimension of a rectangular park : 600 ft by 1000 ft

In drawing, it was of 12 inches by 20 inches.

Let the scale that the drawing is using be k feet to s inches, then

[tex]\rm 1\: ft : \dfrac{s}{k}\: in.[/tex]

Since it is given that 600 ft : 12 inches and 1000 ft : 20 inches, thus, we get:

[tex]\rm 1\: ft : \dfrac{s}{k}\: in.\\\\600 \: ft = \dfrac{600\times s}{k} \: in. = 12 \: in.\\\\\dfrac{600 \times s}{k} = 12\\\\\dfrac{s}{k} = \dfrac{12}{600} = 0.02[/tex]

Thus, every feet is reduced 0.02 times in drawing.

Now,

it is given that in drawing, the rectangular area for swing sets is 0.5 inch to 2 inch.

Let its real length was L and real width was W. Then we have:
[tex]\rm L \times 0.02 = 0.5 \\\\L = \dfrac{0.5}{0.02} = 25 \:\\\\W \times 0.02 = 2 \\W = \dfrac{2}{0.02} = 100[/tex]

Since these are only magnitudes, and unit was converted from feet to inches, so we have L = 25 feet and W = 100 feet

Thus,

The actual length of the swing set area of the park is 25 ft long and 100 ft wide

Answer:

-3/8

Step-by-step explanation:

(-2/3)³ / x = (9/8) -²

-2³/3³ = (2³/3²)²x

-2³/3³ = (2^6/3^4)x

-2³ × 3^-3 × 3^4 × 2^-6 = x

-2^-3 × 3 = x

x = -3/8

The first one is 1:4 and the second is 4:1.

All there is to do is simple division (or simplifying). In the first set of two numbers side length is 6 and perimeter is 24. So if it's side length to perimeter then 6 to 24 which can be simplified to 1 to 4 and just switch the numbers with perimeter to side length.

Answer:

1. Side length to perimeter = 1:4

2. Perimeter to side length = 4:1

Step-by-step explanation:

Ok, so ratios are basically a way to compare two things.

For example, if someone askes the ratio of boys to girls in Mrs. White's class. Say there are 12 boys and 9 girls.

boys to girls = 12 to 9

That's a ratio!

Ratios are typically written like "12 to 9" (with the word "to") or "12:9" (with a colon) but there are also other ways.

In THIS question, you have to find the ratio of side length to perimeter and then vice versa. So, we see that the first number listed for side length is 6, and the first number for perimeter is 24. As we look down the chart, we should notice a pattern- the perimeter is 4 times as much as the side length! Therefore, the ratio of side length to perimeter is 1:4. To find the ratio of perimeter to side length, we just switch the order of the numbers. Now it's 4:1.

There! It's pretty simple! You just are finding the unit ratio!

Answer:

(8, 5): No

(8, 0): Yes

(4, -2): Yes

(-6, -4) No

Step-by-step explanation:

For this question, it is very easy, you just substitute the values under (x,y) into the equation above

The equation is: 3x - 7y > 10

And the x and y values are

(x, y)

(8, 5)

(8, 0)

(4, -2)

(-6, -4)

x values: 8, 8, 4, -6

y values: 5, 0, -2, -4

An ordered pair tells you the location of a point by relating the point's location along the x-axis (the first value of the ordered pair) and along the y-axis (the second value of the ordered pair). In an ordered pair, such as (x, y), the first value is called the x-coordinate and the second value is the y-coordinate.

Now that we know everything, we set up the equation to see if the ordered pair is a solution or not

3x - 7y > 10

Let's substitute (8, 5) into the equation

3(8) - 7(5) > 10

Multiply the numbers

3(8) becomes 24 and -7(5) becomes -35

24 - 35 > 10

-11 > 10

False

So the ordered pair (8,5) is not a solution to the equation

Now for the next ordered pair: (8, 0)

3x - 7y > 10

Let's substitute (8, 0) into the equation

3(8) - 7(0) > 10

3(8) becomes 24 and -7(0) becomes 0

24 - 0 > 10

24 > 10

True

So the ordered pair (8, 0) is a solution to the equation

Now for the next ordered pair: (4, -2)

3x - 7y > 10

Let's substitute (4, -2) into the equation

3(4) - 7(-2) > 10

3(4) becomes 12 and -7(-2) becomes a positive 14, and remember that a negative times a negative becomes a positive

12 + 14 > 10

26 > 10

True

So the ordered pair (4, -2) is a solution to the equation

Now for the next ordered pair: (-6, -4)

3x - 7y > 10

Let's substitute (-6, -4) into the equation

3(-6) - 7(-4) > 10

3(-6) becomes -18 and -7(-4) becomes a positive 28

-18 + 28 > 10

10 > 10

False

Since they are the same number, they should be equal to

So the ordered pair (-6, -4) is not a solution to the equation

Final Answer is [tex]480[/tex]

Step-by-step explanation:

Assume that:

First number = x

Second number = 20 - x

Putting the given conditions,

[tex]2x^{2} + 3(20 - x)^{2} [/tex]

Putting the formula (a-b)²=(a²+2ab+b²) in (20-x)²,

[tex]2 {x}^{2} + 3(20^{2} - 2 \times 20 \times x + {x}^{2})[/tex]

[tex] = > 2 {x}^{2} + 3(400 - 40x + x^{2})[/tex]

Opening the brackets,

[tex]2 {x}^{2} + 3 \times 400 - 3 \times 40x + 3 \times {x}^{2} [/tex]

[tex] = > 2 {x}^{2} - 1200 - 120x + 3{x}^{2}[/tex]

[tex] = > (2x^{2} + 3 {x}^{2}) - 120x + 1200[/tex]

[tex] = > 5 {x}^{2} - 120x + 1200[/tex]

[tex]As \: x= - \frac{b}{2a}[/tex]

[tex] = > - \frac{120}{2 \times 5}[/tex]

[tex] = > - \frac{120}{10} [/tex]

[tex] = > - 12[/tex]

Now substituting the value of x in 5x²-120x+1200,

[tex] = > (5 \times {12}^{2} )-(120 \times 12)+1200[/tex]

[tex] = > (5 \times 144)-(1440)+1200[/tex]

[tex] = > 720 - 1440 + 1200[/tex]

Answer: 6+2x

Step-by-step explanation:

6 is the fixed cost so you add six regardless of how many kilos you travel. You add the 2x because they charge 2 dollars for every extra kilometer. The x is kilometers(which you don’t know how many you travel.) so you add 6+2x to get the cost.

Linear equation is equation in which each term has at max one degree. The formula for the cost of the journey is y = $6 + $2(x).

Linear equation is equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form,

y = mx + c

Linear equation with two variables, when graphed on cartesian plane with axes of those variables, give a straight line.

The given condition can be modelled using a linear relationship.

It is given that there is a fixed charge of $6 and an additional charge of $2 per kilometre. Therefore, the total charge,y can be modeled as,

y = $6 + $2(x)

where x represents the number of kilometres

The formula for the cost of the journey in Words​ is 6 plus two times of x, where x represents the number of kilometres.

Hence, the formula for the cost of the journey is y = $6 + $2(x).

Step-by-step explanation:

6x +2y=42------(1)

8x-4y=36-------(2)

We can actually simplify it, this makes it easier to do and can avoid alot of careless mistakes

3x+y=21---(1)

2x-y=9----(2)

next, we can see that y can be eliminated

(1)+(2),

5x=21 +9

x = 30/5

x=6

substitute x=6 into (2),

2(6)-y=9

y=3

Lastly ,make a conclusion

Thus, x=6, y= 3

[tex] 6x + 2y = 42 \\ 8x - 4y = 36[/tex]

Simplify the first equation

[tex]y = 18 \\ 8x - 4y = 36[/tex]

Multiply both sides of second equation by 1/4

[tex]y = 18 \\ 2x - y = 9[/tex]

Sum the equations vertically to eliminate at least one variable
