4 0

Answer:

Step-by-step explanation:

The general rule is that any 2 must exceed the third in order for a triangle to form. If any one is an exception, it won't work.

A will form a triangle. Any 2 exceeds the third.

B also forms a triangle. Same rule.

C does not work. 7 + 11 = 18 which is the value of the third leg.

D words Any two exceeds the 3rd.

The diameter of a cylindrical construction pipe is 4ft If the pipe is 17ft long, what is its volume? Use the value 3.14 for /pi,

zvonat [6]

Answer:

214 ft^3

Step-by-step explanation:

Here, we are asked to calculate the volume of the cylindrical construction pipe.

Mathematically, the volume V

V = pi * r^2 * h

r is radius = diameter/2 = 4/2 = 2 ft

h = 17ft

pi = 3.14

Putting these values, we have;

V = 3.14 * 2^2 * 17 = 213.52 which is 214 ft^3 to the nearest whole number

KATRIN_1 [288]

One way to test if a graph is a function or not is by doing a vertical line test.

The vertical line test is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.

Hope that helps!

Tristan had 1/3 lb of grapes at home he went to the store and bought 3/8 lb of grapes what fraction of a pound of grapes does Tr

Black_prince [1.1K]

Answer:

Tristan has a 17/24 lb fraction of a pound of grapes now.

Step-by-step explanation:

Given

The number of grapes Tristan had at home = 1/3 lb

The number of grapes Tristan had at the store = 3/8 lb

To determine

What fraction of a pound of grapes does Tristan have now?

In order to get the total fraction of a pound of grapes, all we need is to add the number of grapes Tristan had at home and the number of grapes Tristan had at the store.

i.e.

Current number grapes = 1/3 + 3/8

Least Common Multiple of 3, 8: 24

Adjust fractions based on L.C.M

= 8/24 + 9/24

Apply the fraction rule: $\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}$

= (8 + 9) / 24

= 17/24 lb

Therefore, Tristan has a 17/24 lb fraction of a pound of grapes now.
