A triangular prism is composed of 2 triangles and 3 rectangles.

1 triangle has 2 right triangle, for a total of 4 right triangles.

Area of a right triangle = ab/2 = (3.5m * 2m)/2 = 7/2 = 3.5m²
3.5m² x 4 right triangles = 14 m² total area of the triangle bases.

Rectangle: length = 11 m ; width = 4m
Area of a rectangle = L * W = 11m * 4m = 44m²
44m² x 3 rectangles = 132 m² total area of the rectangle faces

Surface area = 132 m² + 14 m² = 146 m²

A fraction in which the gcf of the numerator and the denominator is 1 is written in blank?

Answers

I guess irreducible form? (translated from my language, maybe it's actually another word?)

The correct answer is:

Simplest form.

Explanation:

We say that a fraction is in "simplest form" if it can no longer be simplified. This means that there are no more factors that can be divided out of the numerator and denominator.

If a numerator and denominator have a GCF of 1, this means the greatest thing that divides both of them is 1. This means that there are no more factors we can divide by, which means there is no more simplification to do; this is simplest form.

What fraction of Emmas garden is planted with vegetables

Answers


We know that different gardens can have different fractions of vegetables
in them.  That right there tells us that we need some information about the
garden in order to know the fraction, because not all gardens are the same.
Since you haven't told us anything about Emma's garden, therefore, we have
no way to answer the question.

. What is the value of r? 0.2(6r − 5) = 8 A. 3.2
B. 7.5
C. 10.8
D 12.4

Answers

0.2(6r - 5) = 8 
1.2r - 1 = 8  ( by distributing 0.2 )
1.2r = 8 + 1( by adding 1 )
1.2r = 9 ( dividing 1.2 on both side )
r = 7.5 Ans

Answer:

7.5

Step-by-step explanation:

0.2(6r-5)                 =8              Distribute.

0.2(6r)-0.2 (5)         =8              Simplify.

1.2r−1                       =8              Add 1 to each side.

1.2r                          =9              Divide each side by 1.2.

1.2r/1.2                     =9/1.2        Simplify.

r                               =7.5

Hope this helps!
