Answer:

The side of the triangle

a=8cm

b=20cm

c=16cm

Step-by-step explanation:

Perimeter = 44 cm

a= x

b=2x+4

c=2x

So the perimeter of a triangle is the sum of its sides

a+b+c=44cm\\x+(2x+4)+(2x)=44cm\\x+2x+2x-4=44cm\\5x=44-4\\x=\frac{40}{5} =8cm

a= 8cm

b=2*8+4=20 cm

c= 2*8= 16 cm

Check:

a+b+c=44cm

(8+20+16)cm=44cm

44cm=44cm

natka813 [3]

Answer:

0.411^5 times 0.599

Step-by-step explanation:

0.599 chance of landing on heads.

0.411 chance of not landing on heads.

0.411 times 0.411 times 0.411 times 0.411 times 0.411 (for the 5 flips that do not land on heads) times 0.599 (for the time that it does land on heads).

Alex the electrician needs 34 yards of electrical wire to complete his job. He has a coil of wiring in his workshop. The coiled
bogdanovich [222]

Answer: This coil will not be enough to complete the job.

Step-by-step explanation:

The circumference of the coil of wiring can be calculated with:

C=2\pi r

Where r is the radius and \pi=3.14

The radius can be calculated by dividing the diameter by 2. Then:

r=\frac{18in}{2}\\\\r=9in

Convert 9 inches to yards (1 yard=36 inches):

(9in)(\frac{1yd}{36in})=0.25yd

Substitute this radius into the formula:

C=2(3.14)(0.25yd)\\C=1.57yd

Since there are 21 circles of wire, you need to multiply C=1.57yd by 21:

C_T=(1.57yd)(21)=32.97yd

The coil has 32.97 yards of wire and Alex needs 34 yards, therefore, this coil will not be enough  to complete the job.
