Could 4.1 cm, 8.4 cm and 1.3 cm be the side lengths of a triangle? A Yes B No

1 answer:

4 0

No, the three given side lengths could not make a triangle.

8.4 cm is greater than 4.1 cm and 1.3 cm combined, so no matter what angle is between the two shorter sides, it is impossible to fit the 8.4 cm side.

Murrr4er [49]

Yo sup??

we know that the sum of all the angles of a triangle is 180

therefore

11x+7x+90=180

18x=90

x=5

exterior angle formed on the ground=180-11x

=180-55

=125

Answer:

6/5m

1 1/5m

Step-by-step explanation:

5 - 3 4/5 = x

5/1 - 19/5 = x

5/1(5/5) - 19/5 = x

25/5 - 19/5 = x

25/5 - 19/5 = 6/5

x = 6/5 or 1 1/5

A store's profit P varies directly with the number of items n that they purchase from a warehouse. Greg's gadgets buys 75 Wacky

Answer:

$P=-2.54n$ .

Step-by-step explanation:

We have been given that a store's profit P varies directly with the number of items n that they purchase from a warehouse.

We know that two proportional quantities are in form $y=kx$ , where y is directly proportional to x ad k is constant of variation.

Upon substituting our given variables, we will get:

$P=kn$

We are also told that Greg's gadgets buys 75 Wacky Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190.50. Let us find constant of proportionality.

$-190.50=k\cdot 75$

$\frac{-190.50}{75}=\frac{k\cdot 75}{75}$

$k=-2.54$

Therefore, our required equation would be $P=-2.54n$ .
