Answer:

m∠DBC is 43°

Step-by-step explanation:

Let us solve the question

∵ D is in the interior of ∠ABC

→ That means D divides ∠ABC into two angles ABD and DBC

∴ m∠ABD + m∠DBC = m∠ABC

∵ m∠ABD = (3x + 5)°

∵ m∠DBC = (5x - 7)°

∵ m∠ABC = 78°

→ Substitute them in the equation above

∴ 3x + 5 + 5x - 7 = 78

→ Add the like terms in the left side

∵ (3x + 5x) + (5 + -7) = 78

∴ 8x + -2 = 78

∴ 8x - 2 = 78

→ Add 2 to both sides

∴ 8x -2 + 2 = 78 + 2

∴ 8x = 80

→ Divide both sides by 8

∴ x = 10

→ To find m∠DBC, substitute x by 10 in its measure

∵ m∠DBC = 5(10) - 7

∴ m∠DBC = 50 - 7

∴ m∠DBC = 43°

Dominic pays 7% interest on his $16,000 college loan and 12% interest on his $12,000 car loan. What average interest rate does h

Naya [18.7K]

The average interest rate is 8.57% paid on the total of $28,000

<h3>What is the percentage?</h3>

The percentage is defined as a ratio expressed as a fraction of 100.

Dominic pays 7% interest on his $16,000 college loan,

And 12% interest on his $12,000 car loan

To determine the average interest rate paid on the total $28,000 he owes

Calculating the total interest amount paid :

⇒ 7% of 16,000 + 12% of 12,000

⇒ (7/100)16,000 + (12/100)12,000

⇒ (0.07)16,000 + (0.12)12,000

⇒ 960 + 1440

⇒ 2400

So the average interest rate paid on the total of $28,000 as

⇒ 2400/28,000 = 0.0857 ≈ 8.57%

Hence, the average interest rate is 8.57% paid on the total of $28,000

A mexican restaurant sells quesadillas in two sizes: a “large” 12 inch-round quesadilla and a “small” 6 inch-round quesadilla. W

Mumz [18]

Answer:

"half of the 12-inch quesadilla" is larger

Step-by-step explanation:

The "inch size" is the diameter of the circular quesadilla.

The area of circle is given by $\pi r^2$

We also know radius is half of diameter.

<u>HALF OF 12-INCH QUESADILLA:</u>

12in diameter = 6 inch radius, the area is:

$\pi(6)^2=36\pi$

Half of this is:

$\frac{36\pi}{2}=18\pi$

<u>ENTIRE 6-INCH QUESADILLA:</u>

6 inch diameter means 6/2 = 3 inch radius

The area of this is:

$\pi(3)^2 = 9\pi$

<u>So, we can say that "half of the 12-inch quesadilla" is larger.</u>
