Keelie has a triangular-shaped card. The lengths of its sides are 3.9 cm, 5.2 cm, and 6.5 cm. Is the card a right triangle?

alexdok [17]

Answer:

Yes

Step-by-step explanation:

Since the longest side is 6.5 cm, so let it be hypotenuse c.

Verifying by right angle formula

c^2=a^2+b^2

(6.5)^2=(3.9)^2+(5.2)^2

42.25=15.21+27.04

42.25=42.25

Hence the given triangle is a right angles triangle

ExtremeBDS [4]

Answer:

17.55 tubs

Step-by-step explanation:

step 1

Find out the total scoops of ice cream in 234 regular cones and 156 large cones

$234(2)+156(3)=936\ scoops$

step 2

Find out the weight of the total scoops

$936(3)=2,808\ ounces$

Convert ounces to pounds

Remember that

1 pound = 16 ounces

To convert ounces to pounds divide by 16

$2,808/16=175.5\ pounds$

step 4

Find out how many ice cream tubs Richard used to make the cones

we know that

A tub of ice cream weighs 10 pounds

Divide the total weight in pounds by 10

$175.5/10=17.55\ tubs$
