Amira and Mandisa sell balloon animals at different stands on the boardwalk. They each use a constant number of balloons per ani

MAXImum [283]

Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.

<h3>Linear equation</h3>

Linear equation is in the form:

y = mx + b

where y, x are variables, m is the slope of the line and b is the y intercept.

Let y represent the number of balloons for x animals.

Amira uses 4 balloons for each animal.

For Mandisa, using the table using (20, 225) and (60, 25):

$slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{25-225}{60-20}=-5$

Therefore Mandisa uses 5 balloons for each animal, this means that Mandisa uses more.

Mr. smith has 5 courses he teaches at the community college. his course a has 102 students with an average tardiness of 3 studen

Furkat [3]

The percentage of tardiness among the 102 pupils is 2.94.

<h2>Calculation of the percentage</h2>

According to the query,

Course A: Total number of students = 102

Number of tardy students = 3

Percent of students tardy in course A = (number of tardy students/total

number of students) * 100

=(3/102)*100

= 2.941

≈2.94

In case of course B: Total number of students = 85 & tardy student = 5

So, the percent of tardy student = (5/85)*100 = 5.88 %

Therefore, it is concluded that the percentage of student tardiness in course A is 2.94.

What is the value of x in the equation below?

denis23 [38]

Answer:

Step-by-step explanation:

Alright, lets get started.

The given equation is :

$1+2e^{x+1}=9$

Subtracting 1 in both sides

$1+2e^{x+1}-1=9-1$

$2e^{x+1}=8$

Dividing 2 in both sides

$e^{x+1}=\frac{8}{2}$

$e^{x+1}=4$

Taking log on both sides

$loge^{(x+1)}=log4$

$(x+1)loge=log4$

Plugging the value of log e as 1

$x+1=log4$

$x=log4-1$ ..................... Answer

Hope it will help :)
