Can 12,35,37 be a right triangle

Answers

Answer 1

Answer:

Answer:

Yes

Step-by-step explanation:

If it could be a right triangle, then 12^2 + 35^2 would have to equal 37^2

12^2 = 144

35^2 = 1225

37^2 = 1369

1225 + 144 = 1369, which is 1369.

That means that it CAN form a right triangle

Step-by-step explanation:

The distance between Vancouver and Winnipeg is approximately 1850 km in a straight line. The distance on a map is 3.7 cm. Write a scale statement for the map. What scale factor was used to make the map.

Answers

3.7cm on the map represents 1850km in reality

3.7cm : 1850km

1cm : 1850/3.7 km

1cm : 500km

Scale statement for map is : 1cm : 500km.

That is 1cm on map represents 500km.

1cm : 500km. Recall 1km = 1000m = 100 000cm

1cm : 500* 100000cm

1cm : 50 000 000cm

1: 50 000 000.

Scale factor is 50 000 000.

Final answer:

The scale of the map is 1 cm : 500 km, meaning 1 cm on the map corresponds to an actual distance of 500 km on the ground. This is the scale factor used to create the map.

Explanation:

The scale of a map is a ratio that represents the relationship between the distance on the map and the actual distance on the ground. In this case, the actual distance between Vancouver and Winnipeg is 1850 km, while the distance on the map is 3.7 cm. Therefore, the scale of the map can be represented as 1 cm : 500 km (because 1850 km / 3.7 cm = approximately 500 km).

This means that 1 cm on the map represents an actual distance of 500 km on the ground, which is the scale factor used to create the map. Therefore, the scale statement for the map would be "1 cm on the map represents 500 km on the ground" or it can be written shorthand as 1:50,000,000 (considering 1 km = 1,000,000 cm).

Which point is on the circle described by (x - 2)2 + (y + 3)2 = 4?A. (2, -5)
B. (2, 0)
C. (0, 0)
D. (1, -4)

Answers

Answer: The correct option is (A) (2, -5).

Step-by-step explanation: We are to select the point that is on the circle described by the following equation :

$(x-2)^2+(y+3)^2=4~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

Option (A) :

(x, y) = (2, -5).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(2-2)^2+(-5+3)^2\n\n=0+4\n\n=4\n\n=R.H.S.$

So, the point (2, -5) lies on the circle (i). And so, option (A) is correct.

Option (B) :

(x, y) = (2, 0).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(2-2)^2+(0+3)^2\n\n=0+9>4=R.H.S.$

So, the point (2, 0) lies outside the circle (i). And so, option (B) is incorrect.

Option (C) :

(x, y) = (0, 0).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(0-2)^2+(0+3)^2\n\n=4+9=13>4=R.H.S.$

So, the point (0, 0) lies outside the circle (i). And so, option (C) is incorrect.

Option (D) :

(x, y) = (1, -4).

We have

$L.H.S.\n\n=(x-2)^2+(y+3)^2\n\n=(1-2)^2+(-4+3)^2\n\n=1+1<4=R.H.S.$

So, the point (2, -5) lies inside the circle (i). And so, option (D) is incorrect.

Thus, (A) is the correct option.

Identify the number as rational or irrational. Explain
-√127

Answers

Solve:-

-√127 = ?
-√127 = -11.2694276695846449

The answer to this is irrational because this number goes on and on forever and it can not be expressed as a ratio, so your answer is irrational.

Hope I helped ya!! xD

Its irrational because the square root of 127 is a decimal that goes on and on and cannot be represented as a fraction. So it is irrational.
Hope this helps.

There are 3 times as many pears are oranges. If a group of children receive 5 oranges each,there will be no left over.If the same group of children receive 8 oranges each, there will be 21 pears left over. How many oranges are there?

Answers

There are 15 oranges

Solution:

Let "x" be the number of oranges

Let "y" be the number of pears

Let "c" be the number of children

There are 3 times as many pears are oranges

Number of pears = 3 times the number of oranges

y = 3x -------- eqn 1

If a group of children receive 5 oranges each, there will be no left over

So, "c" children receives 5 oranges each, there will be no left over

number of oranges = 5(number of children)

x = 5c ------- eqn 2

If the same group of children receive 8 oranges each, there will be 21 pears left over

number of pears = 8 oranges(number of children) + 21

y = 8c + 21

Substitute eqn 1

3x = 8c + 21 ---- eqn 3

Substitute eqn 2

3(5c) = 8c + 21

15c - 8c = 21

7c = 21

c = 3

Substitute c = 3 in eqn 2

x = 5(3)

x = 15

Thus there are 15 oranges

Answer:

15 orangs

Step-by-step explanation:

There are 15 oranges

Solution:

Let "x" be the number of oranges

Let "y" be the number of pears

Let "c" be the number of children

There are 3 times as many pears are oranges

Number of pears = 3 times the number of oranges

y = 3x -------- eqn 1

If a group of children receive 5 oranges each, there will be no left over

So, "c" children receives 5 oranges each, there will be no left over

number of oranges = 5(number of children)

x = 5c ------- eqn 2

If the same group of children receive 8 oranges each, there will be 21 pears left over

number of pears = 8 oranges(number of children) + 21

y = 8c + 21

Substitute eqn 1

3x = 8c + 21 ---- eqn 3

Substitute eqn 2

3(5c) = 8c + 21

15c - 8c = 21

7c = 21

c = 3

Substitute c = 3 in eqn 2

x = 5(3)

x = 15

Thus there are 15 oranges
