Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
lbvjy [14]

Answer:

Area=36.66 cm^2

Step-by-step explanation:

First, you need the height.

Use the Pythagorean theorem:

hypotenuse^2=height^2+(1/2 base)^2  

It's one-half base because it's an equilateral triangle.

1/2 base =4.6

(9.2)^2-4.6^2=height^2

84.64-21.16=height^2

height^2=63.48

height=7.97

Area=(1/2)(base)(height)

Area=(1/2)(9.2)(7.97)=36.66 cm^2

Given that S is the centroid of triangle MNO, find SQ.
AnnZ [28]

Answer:

|SQ|=5

Step-by-step explanation:

If S is the median, then OP is a median of triangle OMN.

This implies that:

|MP|=|NP|

3x-4=x+4

We group like terms and solve for x.

3x-x=4+4

\implies 2x=8

\implies x=4

Now we know that: MN:SQ=2:1

But MN=2x+2

This implies that:

2x+2:SQ=2:1

Put x=4

2(4)+2:SQ=2:1

10:SQ=2:1

Therefore |SQ|=5

2 different companies offer online subscriptions. Company A charges $75 upfront and $20 per month. Company B does not charge the
ki77a [65]

Answer:

15 months

Step-by-step explanation:

Given that company A charges  \$75 upfront and \$20 per month and company B does not charge the upfront fee but charges \$35 per month.

Let after n months both the company charges the same amount.

Total charges by the company A=\$ (75+n\times 20) and total charges by the company B=\$ (n\times 35).

Now, from the given condition both the charges are equal, so

75+n\times 20=n\times 35 \\\Rightarrow 75= 35 n - 20 n\\\Rightarrow 75= 15 n \\\Rightarrow n= \frac {75}{5} \\\Rightarrow n= 15

Hence, after 15 months both the company charges the same amount.

What unit would be best to use for measuring the weight of a stapler?
Alika [10]
<span>The unit that would be best to use for measuring the weight of a stapler are grams. Since a stapler is not too heavy, you don't need a large unit for measurement of weight. Kilograms would be too large, because normally staplers do not weigh a couple of kilograms, but rather a certain number of grams. Hope I helped! :) Cheers!</span>
