The area of a triangular field is 900msquare what is the base of the triangle if the height is 60m

Answers

Answer 1

Answer: Area formula of a triangle is:
A = $(1)/(2)$ bh
We know the are and the height, so substitute to find the base
900 m² = $(1)/(2)$ × b × 60 m
900 = 30b
Divide by 30 to isolate b
$(900)/(30) = (30b)/(30)$
30 and 30 cancels out
b = 30 m

Base of this triangle is 30 m

A marina is in the shape of a coordinate grid. Boat A is docked at (2.4, −3) and Boat B is docked at (−3.4, −3). The boats are ____ units apart.

Answers

A(2.4,-3)(x1,y1) and B(-3.4,-3)(x2,y2). Using distance formula, lABl = $\sqrt{[2.4-(-3.4)] ^(2)+[-3-(-3)] ^(2) } = \sqrt{(2.4+3.4) ^(2)+0 ^(2) } = \sqrt{5.8 ^(2) } = 5.8$

Answer:

It should be 5.8

Step-by-step explanation:

What is the inverse of the function f(x)= 15x+50/x+5

Answers

I think you mean

$f(x) = (15x + 50)/(x + 5)$

First, replace f(x) with y.

$y = (15x + 50)/(x + 5)$

Now, switch x and y.

$x = (15y + 50)/(y + 5)$

Now we solve for y.

$x(y + 5) = 15y + 50$

$xy + 5x = 15y + 50$

$xy - 15y = -5x + 50$

$y(x - 15) = -5x + 50$

$y = (-5x+ 50)/(x - 15)$

Now we replace y with $f^(-1)(x)$ .

$f^(-1)(x) = (-5x+ 50)/(x - 15)$

Jose stores his baseball cards in a box like the one shown

Answers

The formula for volume (V) is l * w * h, where l is length, w is width, and h is height. So in a sense, we have already solved the first part of this problem!

V = 10 * 8 * 3

Now, all we have to do is complete this equation to find the volume.

10 * 8 = 80

80 * 3 = 240

The volume of Jose's box for baseball cards is 240 cubic inches.
Hope that helped! =)

V=lwh

8=l

10=w

3=h

8*10*3=V

V=80*3

V=240

Final Answer: V=240

Jerry built a chest shaped like a rectangular solid. The base was 14 inches long and 10 inches wide. It had a height of 4 inches. What is the area of the base

Answers

Ignore the height dimension and just multiply the side dimensions to get the base area 14in x 10in = 140in^2

If a triangle has 3 side one is 12 one is 72 what is the last sude

Answers

this triangle has 3 sides one is 12, lets call this side a²

another side is 72, lets call this side c²

this triangle must follow Pythagoras therom if it is right angled, that is a²+b²=c²

where a and b are the two shorter sides and c is the longest side (called the hypotenuse) opposite the right angle

to find the last side you do 72² - 12² = 5040

but it is the square root of 5040 which is 70.99 (two decimal places) if you want it in decimal form, if you want it in surd form it is √5040

There is no way to answer that with only the information given.
The 3rd side can be ANY length between 60 and 84. You can't
solve a triangle if you only know 2 sides of it.
