Three times the differnece of fredicos age and 4, increased by 7, is greater than 37. What are possible values of fredicos age?

Anna11 [10]

Answer:

Possible values of fredicos age satisfy $x>14$ where $x$ denotes fredicos age.

Step-by-step explanation:

Let $x$ denotes fredicos age.

Three times the difference of fredicos age and 4, increased by 7 = $3(x-4)+7$

According to the question,

$3(x-4)+7>37\\3(x-4)>37-7\\3(x-4)>30\\x-4>10\\x>10+4\\x>14$

So, possible values of fredicos age satisfy $x>14$

Here, $x$ denotes fredicos age.

Uca is designing a propeller system that consists of 3 blades, each of which is

zmey [24]

Answer:

The weight of the three blades together is $134\ g$

Step-by-step explanation:

step 1

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=4\ in$

assume

$\pi=3.14$

substitute

$A=(3.14)(4)^{2}$

$A=50.24\ in^{2}$

step 2

Find the area of the 3 blades

we know that

The area of the 3 blades represent a central angle of 60 degrees, so

its a 1/6 of the area of complete circle

$A=50.24/6=8.37\ in^{2}$

step 3

Find the weight of the three blades together to the nearest gram

$(8.37\ in^{2})*(16\ g/in^{2})=134\ g$

I NEED HELP!!! ASAP!!!!

Daniel [21]

I hope this helps you

at the 30-60-90 triangle has rules

30=>k

60=>k(square root of) 3

90=>2k

so in this triangle 60=> see 9

k(square root of) 3=9

k=9/(square root of) 3

2k=18/(square root of) 3

at the 45-45-90 triangle rules are

45=>2k

90=>[2k/(square root of 3)] (square root of) 2

x=[18/(square root of 3)].(square root of 2)

x=18(square root of 2)/square root of 3
