Answer:

75 grams

Step-by-step explanation:

If 25 cm = 10 grams

Then 1 cm = 25/10

1 cm = 2.5 grams

To find 30 cm = 2.5 times 30 grams

30 cm = 75 grams

1. **What is the slope of a line that passes through the points (-1,30) and (4, 10)
tresset_1 [31]

Answer:

Slope = -4

Step-by-step explanation:

Given points are :

(-1,30) and (4, 10)

We need to find the slope of the line that passes through these points.

We know that, the formula for the slope of line is given by :

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

We have, x₁ = -1, y₁ = 30, x₂ = 4 and y₂ = 10

Put values in the above formula.

m=\dfrac{10-30}{4-(-1)}\\\\=\dfrac{-20}{5}\\\\=-4

So, the slope of the line is -4.

Which could be the area of the base of the triangular prism?     [Not drawn to scale]6 ft210 ft212 ft220 ft2
Alexus [3.1K]
For this case, the first thing we must observe is that the base of the prism is a triangle.
 The area of the triangle is given by:
 A = (1/2) * (b) * (h)&#10;
 Where,
 b: base of the triangle
 h: height of the triangle
 Substituting values we have:
 A = (1/2) * (4) * (3)&#10;&#10;A = 6 ft ^ 2
 Answer:
 
The area of the base of the triangular prism could be:
 
A = 6 ft ^ 2
