Is 2.4, 4.5 and 5.2 a right triangle?

Mathematics
1 answer:
grandymaker [24]2 years ago
3 0

Answer:

No

Step-by-step explanation:

Use the pythagorian theorm to find whether it's a right triangle or not.

So the hyp will be the largest number. And the hyp must be equal to the sum of b and c squared

5.2 squared= 2.4 squared+ 4m5 squared

27.04= 26.01

It's not equal so the triangle isn't a right triangle.

Jessica traveled to Portland by car. Going there took 3 hours, and the return trip lasted 6 hours. Jessica averaged a speed of 4
Nataly_w [17]

Answer:

The average speed of the trip there is <u>86 mph.</u>

Step-by-step explanation:

Given:

Time taken to reach Portland = 3 hours

Time taken to come beck from Portland = 6 hours

Average speed for the returning trip = 43 mph

Distance traveled for the returning trip can be obtained by multiplying the returning speed by returning time. Therefore, distance for returning trip is:

D=speed\times time=43\times 6=258\ miles

Now, distance traveled for the return trip is same as going to the trip.

So, distance traveled by Jessica going to Portland = 258 miles.

Time taken to go there = 3 hours

Therefore, speed of the trip there is given as the ratio of distance and time and is given as:

\textrm{Average speed}=\frac{Distance}{Time}\\\textrm{Average speed}=\frac{258}{3}=86\ mph

Therefore, the average speed of Jessica's car to go to Portland is 86 mph.

Determine whether each scale factor produces an expansion or a contraction under a dilation of the original image
blondinia [14]

Answer:

see the explanation

Step-by-step explanation:

we know that

If the absolute value of the scale factor is less than 1, then the dilation produces a contraction of the original image

If the absolute value of the scale factor is greater than 1, then the dilation produces an expansion of the original image

so

<u><em>Verify each value</em></u>

1) -4

\left|-4\right|=4

4> 1

therefore

The dilation produces an expansion of the original image

2) 0.25

\left|0.25\right|=0.25

0.25 < 1

therefore

The dilation produces a contraction of the original image

3) -2/3

\left|-2/3\right|=2/3

2/3 < 1

therefore

The dilation produces a contraction of the original image

4) 2.3

\left|2.3\right|=2.3

2.3 > 1

therefore

The dilation produces an expansion of the original image
