Mathematics
1 answer:
nlexa [21]3 years ago
3 0

Answer:

3.2%; 3.2/100; 32/1000; 0.0032

Step-by-step explanation:

Given

3.2\%

Required

Select all equivalents

First, we have:

Number = 3.2\%

Express as fraction

Number = \frac{3.2}{100} ---- this is an equivalent

Multiply the fraction by 10/10

Number = \frac{3.2*10}{100*10}

Number = \frac{32}{1000} --- this is also an equivalent

Express as decimal

Number = 0.0032 --- this is also an equivalent

Solve the equation
motikmotik

Answer:

D

Step-by-step explanation:

\frac{1}{2} (2x + 2) - \frac{1}{4} (3x - 1) = 15

multiply through by 4 ( the LCM of 2 and 4 ) to clear the fractions

2(2x + 2) - (3x - 1) = 60 ← distribute parenthesis and simplify left side

4x + 4 - 3x + 1 = 60

x + 5 = 60 ( subtract 5 from both sides )

x = 55

How do you find surface area of a triangular prism ?​
Vitek1552 [10]

Answer:

See below.

Step-by-step explanation:

To find the surface area, find the area of the square base and add it to the area of each triangle face. Find the area of the base by multiplying base length by base length. Find the area of each triangle face by multiplying 1/2 * b*h.

Example:

For a base which is 12 by 12. The area is 12 x 12 = 144.

For the triangle face, the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.

Together the surface area is 360 + 144 = 504.
