Answer:

\sf \:  \longmapsto\frac{x}{6}  + 2 = 16

\sf \:  \longmapsto\frac{x}{6}  = 16 - 2

\sf \: \longmapsto \frac{x}{6}  = 14

\sf \: \longmapsto \: x = 14 \times 6

\sf \:  \longmapsto \: x = 84

Answer:

\boxed{\boxed{\sf x=84}}

Step-by-step explanation:

\sf \cfrac{x}{6} +2=16

<u>Multiply both sides of the equation by 6:</u>

\sf x+12=96

<u>Subtract 12 from both sides:</u>

\sf x=96-12

<u>Subtract 12 from 96:</u>

\sf x=84

Identify at least one confounding variable that undermines the conclusion drawn in the following fictional study:
soldi70 [24.7K]

Answer:

Identifying at least one confounding variable that undermines the conclusion drawn in the fictional study is:

All students took the same comprehensive test.

Step-by-step explanation:

In a study, an independent variable causes an effect on the dependent variable. But a confounding variable is the variable that influences the independent variable as well as the dependent variable.  If this third variable is not controlled, it might lead the researcher to make a wrong estimate of the relationship that exists between the independent variable and the dependent variable.

Andrew wants to know how many 3/16 pound servings are in a bag containing 7/8 pound of granola.
PilotLPTM [1.2K]
PART A:
x = how many 3/16 pound servings are in the bag.
3/16x = 7/8
PART B:
You need to turn these fractions into decimals:
3/16 = 0.1875
7/8 = 0.875
Rewrite the equation:
0.1875x = 0.875
Solve algebraically. Divide both sides by 0.1875.
0.875/0.1875 = 4.67
x = 4.67.
There are 4.67 3/16 pound servings in a bag containing 7/8 pounds of granola.

What is the measure of EBC ?<br> ___ degrees
erma4kov [3.2K]

Answer:

The measure of arc EBC is 220°

Step-by-step explanation:

step 1

Find out the measure of angle COB

we know that

m∠COB+m∠DOC=90°  -----> given problem

we have that

m∠DOC=m arc DC -----> by central angle

m arc DC=50°

so

m∠DOC=50°

Find m∠COB

m∠COB+50°=90°

m∠COB=40°

step 2

Find out the measure of arc BC

we have that

m arc BC=m∠COB -----> by central angle

m∠COB=40°

therefore

m arc BC=40°

step 3

Find out the measure of arc EBC

we know that

m arc EBC=m arc EB+m arc BC

m arc EB=180° -----> because the diameter divide the circle into two equal parts

so

m arc EBC=180°+40°=220°

A small cargo plane currently has 140 pounds of cargo aboard. In addition, n boxes weighing 45 pounds each will be brought aboar
Vika [28.1K]

Answer:

The inequality that represents this situation is: 140 + 45*n < p

Step-by-step explanation:

Since the plane already had 140 pounds on board and "n" boxes will be loaded on it, then the weigh of each box multiplied by the number of box should be the extra cargo on the plane. This extra cargo added to the previous load must be less than the limit of cargo the plane can take as shown below:

140 + 45*n < p
