Answer:

yes..... because when we solved this equation then we find that both are equal....

Step-by-step explanation:

4(x+1) - 3= 4x + 1

4x+4-3=4x + 1

4x+3=4x + 1

now look what is equivalent expression....

A rectangular bed of a truck is 1 9/10 meters long,1 1/2 meters wide, and 1/2 meter tall. What is the volume of the truck bed?

Sophie [7]

Answer:

The volume of the truck bed is $1\frac{17}{40}\ m^{3}$

Step-by-step explanation:

we know that

The volume is equal to

$V=LWH$

substitute the values , but first convert to an improper fractions

$L=1\frac{9}{10}\ m=\frac{10*1+9}{10}=\frac{19}{10}\ m$

$W=1\frac{1}{2}\ m=\frac{1*2+1}{2}=\frac{3}{2}\ m$

$H=\frac{1}{2}\ m$

Find the volume

$V=(\frac{19}{10})(\frac{3}{2})(\frac{1}{2})=\frac{57}{40}\ m^{3}$

Convert to mixed number

$\frac{57}{40}\ m^{3}=\frac{40}{40}+\frac{17}{40}=1\frac{17}{40}\ m^{3}$

Surface of the cylinder : 2*(pi*radius^2)+(2*pi*radius*height)=2(pi*1.5^2)+(2*pi*1.5*9)=31.5pi cm^2 ~99 cm^2

Volume : pi*radius^2*height=pi*1.5^2*9=20.25pi~64 cm^3

USING OLDER BROS ACC THIS IS HOW MUCH I NEED HELP PLEASE BE QUICK--------------------

Given:
Rectangle: 320 x 190
triangle: base: 305
I'm assuming that the unit measure is in miles.

I found a map of Nevada and I figured that the length of the rectangle is serving as the height of the triangle.

Area of the rectangle = Length * width
A = 320 mi x 190 mi
A = 60,800 sq. mi.

Area of a triangle = (height * base) / 2
A = (320 mi x 305 mi) / 2
A = 97,600 sq. mi / 2
A = 48,800 sq. mi.

Total Area = 60,800 + 48,800 = 109,600 square miles.
