True [87]3 years ago

Answer:

When we think of World War I, images of the bloody, muddy Western Front are generally what come to mind. Scenes of frightened young men standing in knee-deep mud, awaiting the call to go "over the top", facing machine guns, barbed wire, mortars, bayonets, hand-to-hand battles, and more. We also think of the frustrations of all involved: the seemingly simple goal, the incomprehensible difficulty of just moving forward, and the staggering numbers of men killed. The stalemate on the Western Front lasted for four years, forcing the advancement of new technologies, bleeding the resources of the belligerent nations, and destroying the surrounding countryside. I've gathered photographs of the Great War from dozens of collections, some digitized for the first time, to try to tell the story of the conflict, those caught up in it, and how much it affected the world. This entry is part 2 of a 10-part series on World War I. This installment focuses on Early Years on the front, part II will focus more on the final year of trench warfare.

Work out the surface area of this solid prism.
alexandr1967 [171]

Answer:

2520cm²

Step-by-step explanation:

Surface area = sum of the area of all the bases.

Area of bottom base = 28 * 30 = 840

Area of right base = 25 * 30 = 750

Area of left base = 17 * 30 = 510

Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420

Then add all the areas together to find surface area

Surface area = 840 + 750 + 510 + 420 = 2520cm²

Relevant Formulas:

Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base

Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles.

Find the slope of the line passing through the points (-5, 3) and (7,9).
dybincka [34]

Answer:

\huge\boxed{slope=\dfrac{1}{2}=0.5}

Step-by-step explanation:

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points

(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9

Substitute:

m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}

I will give you brainliest!!!! Use substitution method to solve the system of equations. y=6x-5 y=x+5
solong [7]

Answer:

(2,7)

Step-by-step explanation:

y=6x-5

y=x+5

Since they are both equal to y, set them equal to each other

6x-5 = x+5

Subtract x from each side

6x-x-5 = x+5-x

5x-5 = 5

Add 5 to each side

5x-5 +5 = 5+5

5x=10

Divide by 5

5x/5 = 10/5

x=2

y = x+5

y = 2+5

y =7
