Answer:

135 steps

Step-by-step explanation:

Each member marches:

50 + 40 = 90 yards

Convert this to feet:

1 yard = 3 feet
90 yards = 3*90 feet = 270 feet

Find the number of steps:

270/2 = 135 steps

<h3>Total marched distance:-</h3>

50+40=90yards

Convert to feet

1yard=3ft

90yards=90(3)=270ft

No of steps

$\\ \sf\longmapsto \dfrac{270}{2}=135steps$

Mai wants to make an open top box by cutting out corners of a square piece of cardboard and folding up the sides. The cardboard

Bumek [7]

Answer:

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

The domain for x is all real numbers greater than zero and less than 5 com

Step-by-step explanation:

The question is

What is the volume of the open top box as a function of the side length x in cm of the square cutouts?

see the attached figure to better understand the problem

Let

x -----> the side length in cm of the square cutouts

we know that

The volume of the open top box is

$V=LWH$

we have

$L=(10-2x)\ cm$

$W=(10-2x)\ cm$

$H=x)\ cm$

substitute

$V(x)=(10-2x)(10-2x)x\\\\V(x)=(100-40x+4x^{2})x\\\\V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

Find the domain for x

we know that

$(10-2x) > 0\\10> 2x\\ 5 > x\\x < 5\ cm$

The domain is the interval (0,5)

The domain is all real numbers greater than zero and less than 5 cm

therefore

The volume of the open top box as a function of the side length x in cm of the square cutouts is

$V(x)=(4x^{3}-40x^{2}+100x)\ cm^3$

Bess [88]

Answer:

The answer in the attached figure

Step-by-step explanation:

Let

x------> the abscissa

y-----> the ordinate

we know that

$y=2x$ -----> given problem

The domain is $[-1, 0, 1]$

For $x=-1$

$y=2(-1)=-2$

The point is $(-1,-2)$

For $x=0$

$y=2(0)=0$

The point is $(0,0)$

For $x=1$

$y=2(1)=2$

The point is $(1,2)$

Find the Simple Interest $700 deposited at an interest rate of 1.5% for 3 years

slega [8]

Answer:

$31.50

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 1.5%/100 = 0.015 per year,

then, solving our equation

I = 700 × 0.015 × 3 = 31.5

I = $ 31.50

The simple interest accumulated

on a principal of $ 700.00

at a rate of 1.5% per year

for 3 years is $ 31.50.
