Drag numbers to fill in the table to organize the information in this problem. Carter works for a fence company. He can paint a

OLEGan [10]

Answer:

394.67 minutes (or about 6.58 hours)

Step-by-step explanation:

<u>For 145.8 feet long fence:</u>

At a rate of 2.25 feet per minute, its gonna take him

$\frac{145.8}{2.25}=64.8$ minutes to pain

Also

At a rate of 0.75 feet per minute, its gonna take him

$\frac{145.8}{0.75}=194.4$ minutes to stain

<u>For 76.2 feet long fence:</u>

At a rate of 2.25 feet per minute, its going to take him

$\frac{76.2}{2.25}=33.87$ minutes to pain

At a rate of 0.75 feet per minute, its gonna take him

$\frac{76.2}{0.75}=101.6$ minutes to stain

In total, it's gonna take him:

64.8 + 194.4 + 33.87 + 101.6 = 394.67 minutes

In hours, that is 394.67/60 = 6.58 hours

Can someone please explain to me the difference between SAS and SSS in Geometry when dealing with triangle proofs?

ANTONII [103]

Hello from MrBillDoesMath!

Answer: SAS = side - angle -side congruence

SSS = side - side - side congruence

Discussion :

In Plane Geometry, identical triangles are said to be "congruent". There are several ways, depending upon the information you have, to prove 2 triangles are congruent.

In one approach ("SSS") if you can show that 2 triangles have identical side lengths, then the triangles are congruent. (A triangle has 3 sides, hence "SSS" -- 3 S's; 3 sides, get it?)

In another approach ("SAS") if you can show that 2 sides, and the angle included between those sides, in one triangle are identical to the sides and included angle in another triangle, then the triangles are congruent

It's easier to understand this with a picture or diagram than in words. Please review the SSS, SAS picture in your textbook

What information do you need to find the area of a triangle using trigonometry?

SCORPION-xisa [38]

Formula of the area of triangle
A=(1/2)a*b*sin(C)
a, b - sides
C- an angle between sides a and b.
Probably, this question means that you need to know sin of the angle.

Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$
