Answer:

The train travels at 120 miles per hour.

Step-by-step explanation:

All we have to do is divide 540 by 4.5

1/10 and 8/100 which is the correct sum

Ivanshal [37]

To add 1/10 and 8/100, they must have the same denominator.

To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).

Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.

This results in 18/100, which can be simplified to 9/50.

Enter the inequality of the graph below.

aev [14]

The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y $\leq$ -3x+8

Find the value of 85²-15² using the difference of two squares method

Mekhanik [1.2K]

Answer:

$7000$

Step-by-step explanation:

Recall the form of the difference of squares.

$x^2 - y^2 = (x+y)(x-y)\\\\\\$

Now let's apply it to your numbers:

$85^2 - 15^2 = (85 + 15)(85 - 15)$

Simplify:

$(100)(70) = 7000$

A prism and two nets are shown below:

vladimir1956 [14]

A) Net A would be the correct net for the prism.

B) AB = 3in
BC = 5in
CD = 8.6in

C) area of one triangle : 4*3/2 = 6
But there's 2 triangles so 6*2 = 12cm2
Area of the middle square : 8.6*4 = 34.4cm2
Area of bottom square : 8.6*5 = 43cm2
Area of top rectangle : 8.6*3 = 25.8cm2

Finally add all of these areas together and you will get the surface area : 115.2cm
