its a right triangle 20ft and 24ft?

Answers

Answer:

a triangle, I'm guessing 20ft and 24 ft on the outsides,

would be:

Equation to get the area of a triangle: (A*B)/2

(20*24)/2=Area

20*24= 480

480/2= 240

area= 240

Answer: 240 ft²

Step-by-step explanation:

1. Multiply the base and the height.

2. Divide the product you get by 2.

=> 20 * 24 = 480

=> 480 / 2 = 240

In a right triangle, the shortest leg is 15 centimeters, and one angle equals 30 degrees, what is the length of the
hypotenuse?

Answers

the hypotenuse is 30 cm
ALSO UR PFP IS SO FUNNY-

Answer:

30

Step-by-step explanation:

This is a 30 60 90 triangle. Since it tells us it a right triangle (which means it has a 90 degree angle). Also it tells us that there is a 30 degree. Using the triangle interior theorem, the third angle is a 60 degree

angle

The longest side or hypotenuse is twice the length of the shortest side. So the hypotunes is 30.

George weeded 1/4 of the garden, and summer weeded, some too. When they were finished, 2/5 of the garden still needed to be weeded. What fraction of the garden did summer weed?

Answers

Answer: [tex]\dfrac{7}{20}^{th}\ \text{Part}[/tex]

Step-by-step explanation:

Given

George weeded [tex]\frac{1}{4}[/tex] of the garden

When they both finish, [tex]\dfrac{2}{5}[/tex] of the garden still needed to be weeded

Suppose Summer weeded  [tex]\dfrac{1}{x}[/tex] part

[tex]\Rightarrow \dfrac{1}{4}+\dfrac{1}{x}=1-\dfrac{2}{5}\\\Rightarrow \dfrac{1}{4}+\dfrac{1}{x}=\dfrac{3}{5}\\\Rightarrow \dfrac{1}{x}=\dfrac{3}{5}-\dfrac{1}{4}\\\Rightarrow \dfrac{1}{x}=\dfrac{12-5}{20}=\dfrac{7}{20}[/tex]

So, summer weeded [tex]\dfrac{7}{20}\ ^{th}[/tex] part of the garden

A rental car company charges $38.38 per day to rent a car and $0.14 for every mile driven. Camden wants to rent a car, knowing that: He plans to drive 350 miles. He has at most $270 to spend. Which inequality can be used to determine xx, the maximum number of days Camden can afford to rent for while staying within his budget?

Answers

Answer:

5.75 days

Step-by-step explanation:

Given data

let the number of days be x and the number and the number of miles be y

so that the cost of the rental will be

c= 38.38x+ 0.14y---------1

we are told that the amount at hand is $270

hence

270=38.38x+ 0.14*(350)

solve for x

270= 38.38x+49

270-49= 38.38x

221= 38.38x

divide both sides by 38.38

x= 221/38.38

x= 5.75 days

Hence the  number of days is 5.75 days
