What is a cube number that us greater than 100 but less that 200

1 answer:

3 0

Let the number be H T O. Ones digit = O Given that. O =10−5 ⇒ O =5. Also is given that tens digit T is 2 more than ones digit O ⇒ tens digit T = O +2=5+2=7. ∴ The number is. H 75. Given also is that "number is less than 200 and greater than 100 " ⇒ H can take value only =1. We get our numberas 175.

A plane traveled 1463 miles to Moscow and back. The trip there was with the wind. It took 11 hours. The trip back was into the w

Studentka2010 [4]

The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.

Step-by-step explanation:

Given,

The distance traveled by plane = 1463 miles

The trip with the wind took 11 hours.

The trip took 19 hours against the wind.

Let,

s be the speed of plane and w be the speed of wind.

Therefore;

Speed with the wind = s+w

Speed into the wind = s-w

We know that;

Distance = Speed * Time

Therefore;

Equation for trip taken with wind.

1463 = 11(s+w)

Dividing both sides by 11

$\frac{1463}{11}=\frac{11(s+w)}{11}\\133=s+w\\s+w=133\ \ \ Eqn\ 1$

Equation for trip taken into the wind

1463 = 19(s-w)

Dividing both sides by 19

$\frac{1463}{19}=\frac{19(s-w)}{19}\\77=s-w\\s-w=77 \ \ \ Eqn\ 2$

Adding Eqn 1 and 2

$(s+w)+(s-w)=133+77\\s+w+s-w=210\\2s=210$

Dividing both sides by 2

$\frac{2s}{2}=\frac{210}{2}\\s=105$

Putting s=105 in Eqn 1

$105+w=133\\w=133-105\\w=28$

The speed of plane is 105 miles per hour and speed of wind is 28 miles per hour.

Can y’all help me with this answer ASAP

viktelen [127]

Answer:

sqrt(24)

Step-by-step explanation:

The number is slightly less than 5

We know that 5^2 =25

sqrt(25) = 5

so the number has to be less that sqrt(25)

The only number less than sqrt(25) is sqrt(24) and sqrt(20)

sqrt(20) is too far away to be slightly less than 5 so it must be sqrt(24)

What is the slope-intercept form of the function that contains the point (8, 12) and has a slope of _2?

Crank

The function has a slope : m = - 2 and contains the point ( 8, 12 ).
y = m x + b
12 = ( - 2 ) * 8 + b
12 = - 16 + b
b = 12 + 16
b = 28
The slope-intercept form of the function is:
y = - 2 x + 28
