Sixty-four percent of the students correctly described the process of photosynthesis. If 63 students did not correctly describe

olganol [36]

Answer:

Number of students who correctly describe the process = 112 students.

Step-by-step explanation:

<em>From the information provided in the question;</em>

<em>64% correctly described the process of photosynthesis.</em>

<em>63 students didn't describe correctly the process of photosynthesis.</em>

We are to find the number of students that did correctly describe the process of photosynthesis.

First of all we need to find the total number of students.Lets represent this value to be x

percentage of students who incorrectly describe the process = (100-64)%

=36%

$\frac{36}{100}*x =63$

x= 63*100/36

x=175 students.

FIRST METHOD

Number of students who correctly describe the process = $\frac{64}{100}*total number of students$

= $\frac{64}{100}*175$

Number of students that correctly describe the process = 112 students.

SECOND METHOD

Number of students who correctly describe the process = Total number of students- number of students who didn't correctly describe the process

Number of students who correctly describe the process = 175-63

Number of students who correctly describe the process = 112 students.

Decide whether the sets are equivalent {d: d is a month of the year} and {g : g is a state in the United States}

Mekhanik [1.2K]

Answer:

<h2>Non equivalent</h2>

Step-by-step explanation:

The equivalent between sets is determined by the number of elements. If two sets have the same number of elements, then they are equivalent sets.

In this case, a year has 12 months, and the US has 50 states. So, one month is not equal to 1 state because they have different natures and they represent a different proportion. A month represents 1/12 of a year and a state represents 1/50 of the total number of states.

Someone please explain how to do this question

Answer:

1. 37.0 in²

2. 55 m²

Step-by-step explanation:

1) all angles in an equilateral triangle are 60°

The dotted line is an angle bisector which also divides the triangle into two congruent right angle triangles

Find the base using trig ratio

cos(30) = 8/base

base = 16sqrt(3)/3

Area = ½ × 16sqrt(3)/3 × 8

= 36.95041723 in²

2. d1: 5 + 5 = 10

d2: 3 + 8 = 11

Area = ½ × 10 × 11

= 55 m²
