the assumption here being that both lines JH and FH are tangent lines to the circle, if that's the case the external angle of 34° is the angle made by the equal tangents, meaning the triangle is an isosceles with twin sides.

In an isosceles triangle the twin sides make also twin angles, so the angles at J and F are twins, and they'd be 180° - 34° = 146° total, since they're twins, each one takes half, or 73°.

Alice had $4.80 left after spending 40 percent of her money on lunch, 20 percent of what was left after lunch on parking, and 50

Vitek1552 [10]

Answer:

$20

Step-by-step explanation:

We are given the percentages of how much she spent on each purchase but we need the percentage of what is left after each purchase. We calculate this by subtracting each percentage from 100% like so.

100% - 40% = 60%

100% - 20% = 80%

100% - 50% = 50%

Next we need to do is change the percentages into decimal format. We do this by moving the decimal 2 digits to the left. Therefore the percentages wasted are the following

60.0% ⇔ 0.60

80.0% ⇔ 0.80

50.0% ⇔ 0.50

Now that we have the percentages in decimal format we can calculate the total price (t) by retracing the spending process. The spending process was following.

$t_{2} = 0.60t$

$t_{3} = 0.80t_{2}$

$4.80 = 0.50t_{3}$

So we have to retrace by solving for $t_{3}$ , then $t_{2}$ , and finally (t)

$4.80 = 0.50t_{3}$ ... divide both sides by 0.50

$9.60 = t_{3}$

$9.60 = 0.80t_{2}$ .... divide both sides by 0.20

$12 = t_{2}$

$12 = 0.60t$ .... divide both sides by 0.60

$20 = t$

Finally we can see that the Total amount of money that Alice had before lunch was $20

Courtney is ordering nachos at a restaurant, and the server tells her that she can have up to three toppings: pico de gallo, oni

aalyn [17]

Answer:

$Probability = \frac{1}{9}$

Step-by-step explanation:

Given

Toppings: Pico de gallo, Onions and Steak

Required

The probability of getting Onions and Steak

The probability is calculated using:

$Probability = P(Onion)\ and\ P(Steak)$ --- because the events are independent

$P(Onion) = \frac{n(Onion)}{Total}$

$P(Onion) = \frac{1}{3}$

$P(Steak) = \frac{n(Steak)}{Total}$

$P(Steak) = \frac{1}{3}$

So, we have:

$Probability = P(Onion)\ and\ P(Steak)$

$Probability = P(Onion)\ *\ P(Steak)$

$Probability = \frac{1}{3} * \frac{1}{3}$

$Probability = \frac{1}{9}$

Please help, will give brainliest!<br>(please explain how as well)

vovikov84 [41]

Answer:

C

Step-by-step explanation:

Since GJ bisects ∠ FGH , then ∠ FGJ = ∠ JGH = x + 14

∠ FGH = ∠ FGJ + ∠ JGH , substitute values

4x + 16 = x + 14 + x + 14 = 2x + 28 ( subtract 2x from both sides )

2x + 16 = 28 ( subtract 16 from both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Thus

∠ FGJ = x + 14 = 6 + 14 = 20° → C
