Answer:

∠MON = 130

Step-by-step explanation:

∠LON = 180°

∠LOM + ∠MON = 180 -------equation

where:

∠LOM = 4x + 30

∠MON = 8x + 90

plugin values into the equation

4x + 30 + 8x + 90 = 180

4x + 8x + 30 + 90 = 180

12x = 180 - 30 - 90

12x = 60

x = 60/12

x = 5

plugin values to ∠MON = 8x + 90

∠MON = 8x + 90

∠MON = 8(5) + 90

∠MON = 130

Answer:

LOM= 130º

Step-by-step explanation:

Combine the two equations and set it to equal 180º(LON), 180º=12x+120º

next subtract 120º from both sides, 60º=12x. Now divide both sides by 12, 5=x. Now you can plug 5 back into the original equation to calculate MON, 8x5+90º

Tom works for a company his normal rate of pay 15 per hour

Brrunno [24]

The amount earned by Tom is the product of the rate per hour and the number of hours worked which is $90.

The amount earned per hour = $15

The number of hours worked = 6 hours

The amount earned at the normal earning rate can be calculated thus :

Normal rate per hour × number of hours

Amount earned = $15 × 6 = $90

Therefore, the amount earned by Tom after working for 6 hours at the normal rate is $90.

Sandra is making the shape of a rhombus. The first three angles are 75°, 75°, and 105°. What is the measure of the fourth angle?

mrs_skeptik [129]

Its 105° because the rhombus is essentially a square or rectangle of sorts and at least 2 sides have to be alike

Students received grades with or - (example B ). Of all students who received one or more plus grades, 92% were undergraduates a

MrMuchimi

Answer:

The probability that a student is an undergraduate student, given that the student received a plus grade is 0.92

Step-by-step explanation:

The conditional probability of an event B given that another event A has already occurred is:

$P(B|A)=\frac{P(A\cap B)}{P(A)}$

Denote the events as follows:

X = a students is a graduate

Y = a students is a under-graduate

+ = a student received one or more plus grades

- = a student received one or more minus grades

Consider the tree diagram below.

According to the tree diagram, the probability that a student is an undergraduate student, given that the student received a plus grade is:

P (+ | Y) = 0.92

Thus, the probability that a student is an undergraduate student, given that the student received a plus grade is 0.92.
