<h3><u>Answer:</u></h3>

Hence, the inequality that will represent the marks he needs  is:

4x+8y≥50

<h3><u>Step-by-step explanation:</u></h3>

On a final exam, each multiple-choice question is worth 4 points and each word problem is worth 8 points.

Lorenzo needs at least 50 points on the final to earn a "B" in the class.

Let x be the number of correct multiple-choice questions, and y, the number of correct word problems.

Hence, the inequality that will represent the marks he needs  is:

4x+8y≥50

standing on the street, the top of a building has an angle of elevation of 20 degrees. You walk 300 feet directly toward the bui
densk [106]

Answer:

The value of height of the building  h = 509.2 feet

Step-by-step explanation:

From the Δ A B C

\tan 25 = \frac{h}{y}

⇒ h = y \tan 25°  ------- (1)

From Δ A B D

\tan 20 = \frac{h}{y + 300}

⇒ h = ( y + 300 ) \tan20° ------- (2)

Equation 1 = Equation 2

⇒ y \tan 25° = ( y + 300 ) \tan20°

⇒ 0.46 y = 0.36 y + 109.2

⇒ 0.1 y = 109.2

⇒ y = 1092 feet

Put this value of y in equation ( 1 ) we get,

⇒ h = 1092 × tan 25°

⇒ h = 509.2 feet

This is the value of height of the building.

Find AM in the parallelogram if PN =15 and AO = 6. The diagram is not to scale.
valentinak56 [21]

Answer:

6

Step-by-step explanation:

The diagonals of a parallelogram bisect each other.

The diagonals are PN and MO. The point A divides PN into 2 equal segments as well as MO into 2 equal segments.

Since AO = 6, MA should also be equal. Hence, MA (or AM) = 6.

The correct answer is AM = 6

What is 2 3/5 + 1 3/5
Vlada [557]

Answer: 4 1/5


Step-by-step explanation:

Rewriting our equation with parts separated


=2 + 3/5 + 1 + 3/5


Solving the whole number parts


2 + 1= 3


Solving the fraction parts


3/5 + 3/5 = 6/5


Simplifying the fraction part, 6/5,


6/5 = 1 1/5


Combining the whole and fraction parts


3 + 1+ 1/5 = 4 1/5


Solution by Formulas


converting mixed numbers to fractions, our initial equation becomes,


13/5 + 8/5


Applying the fractions formula for addition,


=(13 × 5) + (8 × 5)/5 × 5


=65+40 / 25


=105/25


Simplifying 105/25, the answer is


=4 1/5
