On Tuesday, a local hamburger shop sold a combined total of 381 hamburgers and cheeseburgers. The number of cheeseburgers sold w

lutik1710 [3]

Answer:

127 hamburgers

Step-by-step explanation:

let c = # of cheeseburgers

let h = # of hamburgers

c = 2h (The number of cheeseburgers sold was two times the number

of hamburgers sold.)

h + c = 381 (combined total)

h + 2h = 381

3h = 381

h = 127

Find the center of the circle whose equation is (x - 8) 2 + (y + 2) 2 = 64.

SashulF [63]

If given the equation, you need to take the number beside the x and y and change their signs to get your point:

x - 8 (Take the -8 and make it +8)

y + 2 (Take the +2 and make it -2)

Your point is (8, -2)

Calculate the distance between the two given point T(6,-2),U(-2,-12)

slava [35]

Use the distance formula: $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

(6, -2), (-2, -12)
$\sqrt{(-2 - 6)^2 + (-12 - -2)^2}$ ⇒ $\sqrt{(-8)^2 + (-10)^2}$
$\sqrt{64 + 100}$ ⇒ $\sqrt{164}$
$\sqrt{164}$ = 12.8

The distance between points T and U is 12.8 units.

Determine the measure of ∠Y. images attached

Gwar [14]

Answer:

<h3>The answer is option C</h3>

Step-by-step explanation:

Since it's a right angled triangle we can use trigonometric ratios to find the value of ∠Y

To find the value of ∠Y we use tan

We have

$\tan(∠Y) = \frac{25}{20} \\ \tan(∠Y) = \frac{5}{4} \\ ∠Y = { \tan^{ - 1} } \frac{5}{4} \\ ∠Y = 51.34019...$

We have the final answer as

Hope this helps you
