Three lengths will be a triangle only if the sum of two sides is greater than the third side.

19+11 > 17

This is a triangle.

23+28> 52\\51>52\\51 \ngtr 52

This is not a triangle.

9+25> 34\\34>34\\34\ngtr 34

This is not a triangle.

13+14> 22\\27>22

Luna is making a rope ladder. Each step of the ladder is 2 1/3 feet wide and uses an additional 1/2 foot on each end of the step
koban [17]

By taking the quotient between the total length and the length needed for each step, we conclude that Luna can make 9 steps.

<h3>How many steps can she make from the rope?</h3>

To find this, we need to take the quotient between the total length of the rope and the length needed for each step.

She has a total length of 30ft.

For each step she needs (2 + 1/3) ft plus (1/2) ft for each knot, and there are two knots, then each step needs: (2 + 1/3)ft + 2*(1/2)ft = (3 + 1/3) ft.

Then the number of steps that can be made is:

N = (30 ft)/(3 + 1/3) ft. = 9

She can make 9 steps or the lader.

Which linear function represents the line given by the point-slope equation y + 1 = –3(x – 5)?
Juliette [100K]
Y + 1 = -3(x - 5)
y + 1 = -3x + 15
y = -3x + 15 - 1
y = -3x + 14 <== or f(x) = -3x + 14

Miguel's cat, Chester, weighs 6.8 pounds. Chester's vet tells Miguel to feed the cat 3 4 of an ounce of canned food daily for ea
Vitek1552 [10]

Answer:

0.4 ounces

Step-by-step explanation:

In a day

Miguel is to feed Chester ,

Chester can eat 3/4 of an ounce for each pound of body weight.

Chester weighs 6.8 pounds

Hence:

1 pound = 3/4 ounce

6.8 pounds = x ounces

Cross Multiply

x = 6.8 × (3/4) ounces

x = 5.1 ounces

Chester is to be fed 5.1 ounces of food each day.

The amount of food left after 1 day

= 5.5 ounces - 5.1 ounces

= 0.4 ounces

Hence, 0.4 ounces of food is left after 1 day
