Lara is playing a video game where she hunts for treasure, like these gems:
A sapphire is worth 5 gold coins, and a ruby is worth 8 gold coins.
On her last hunt, Lara found 17 gems, all either rubies or sapphires, and sold them for 100 coins. How many sapphires did she find?
Answer:
12 sapphires
Step-by-step explanation:
Let's call the number of sapphires x. This means the number of rubies is the total number of gems minus x, or 17-x.
# of Sapphires: x
# of Rubies:17-x
A sapphire is worth 5 (gold coins) each, and a ruby is worth 8.
We also know the total amount of money is 100 coins, so
5*x+8*(17-x)=100
5x+136-8x=100
-3x=-36
x=12
Remember:
# of Sapphires: x
# of Rubies:17-x
...so Lara found 12 sapphires and 17-12=5 rubies.
Which equation has a solution of x = 9?

A person in a lighthouse, that is 315ft high, spots a boat in trouble. The angle of depression to the boat is 21°49ʹ. How far from shore is the boat?
NO LINKS
Answer:
786.9 feet to the nearest tenth.
Step-by-step explanation:
In the triangle formed between the boat, base of the lighthouse and the top of the lighthouse, the opposite side to angle 21 49' is the height of the lighthouse and the distance (d) of the boat is the adjacent side.
So we have:
tan 21 49 = 315 / d
d = 315/ tan21 49
= 786.89 ft.

Elena’s backyard is in the shape of a rectangle. She created a triangular-shaped flower bed (shown as the shaded region) to plant flowers in.
The area of the triangular flower bed is square feet. The area of her backyard that does not include the flower bed is square feet.
Answer:
b
Step-by-step explanation:
iS THE ANSWER
Area of background without flower bed = 575 feet²
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that:
Length of rectangle ground = 35 feet
Width of rectangle ground = 20 feet
Height of triangle bed = 10 feet
Base of triangle bed = 25 feet
Now, We can formulate;
Area of background without flower bed = Area of rectangle - Area of triangle
Hence, Area of background without flower bed = [l x b] - (1/2)(b)(h)
Area of background without flower bed = [35 x 20] - (1/2)(25)(10)
Area of background without flower bed = 700 - 125
Area of background without flower bed = 575 feet²
Thus, Area of background without flower bed = 575 feet²

How many combinations of 3 playing cards (from a 52-card deck) exist?
Answer:
22,100
Step-by-step explanation:
pls trust me i just took the test
The number of combination of 3 playing cards from 52 card deck is 22100.
What is Combination?A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.
Here, total cards = 52
cards to be selected = 3
So, total possible combination = ⁵²C₃
= (52 X 51 X 50) / (3 X 2 X 1)
= 22100
Thus, the number of combination of 3 playing cards from 52 card deck is 22100.

The probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.
What is probability?Probability of an event is the ratio of number of favorable outcomes to the total number of outcomes.
Probability is a measure of how likely an event is going to happen.
Given is to find the probability that a point randomly chosen in the large triangle is also in Region A.
We can find the area of region A as -
Area{A} = A{Rectangle} + A{Right triangle}
Area{A} = (Length x Breadth) + (1/2 x base x height)
Area{A} = (5 x 2) + (1/2 x 1 x 2)
Area{A} = 10 + 1
Area{A} = 11 square units
Total area of the region {A + B} as -
Total Area{A + B} = 11 + (1/2 x 10 x 5)
Total Area{A + B} = 11 + 25
Total Area{A + B} = 36 square units
The probability that a point randomly chosen in the large triangle is also in Region A will be -
P{A} = (Area{A}/Total Area{A + B})
P(A) = 11/36
Therefore, the probability that a point randomly chosen in the large triangle is also in Region A will be 11/36.

Janessa is playing a board game with two friends. Using a single die, one friend rolled a four, and the other friend rolled a three. Janessa needs to roll a number higher than both friends in order to win the game, and she wants to calculate her probability of winning.
Is the probability of Janessa winning an independent event or dependent event? Why?
O) Her probability of winning is an independent event because it depends on the results of her friends’ rolls.
O) Her probability of winning a dependent event because it does not depend on the results of her friends’ rolls.
O) Her probability of winning is an independent event because it does not depend on the results of her friends’ rolls.
O) Her probability of winning is a dependent event because it depends on the results of her friends’ rolls.
A satellite is to be put into an elliptical orbit around a moon as shown below. A vertical ellipse is shown surrounding a spherical object labeled, moon. The moon is a sphere with radius of 1000 km. Determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 953 km to 466 km.
Answer:
The correct equation will be "[tex]\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1[/tex]".
Step-by-step explanation:
In the above question, the figure is missing. Please find below the attachment of the figure.
According to the question,
Radius of a moon,
r = 1000 km
The max. distance from moon's surface to the satellite,
a = 953 km
The min. distance from moon's surface to the satellite,
b = 466 km
Now,
As per the question or the diagram,
⇒ [tex]a_1=a+r[/tex]
[tex]=953+1000[/tex]
[tex]=1953 \ km[/tex]
⇒ [tex]b_1=b+r[/tex]
[tex]=466+1000[/tex]
[tex]=1466 \ km[/tex]
hence,
The equation of ellipse will be:
⇒ [tex]\frac{x^2}{b_1^2} +\frac{y^2}{a_1^2} =1[/tex]
On substituting all the values, we get
⇒ [tex]\frac{x^2}{(1466)^2} +\frac{y^2}{(1953)^2} =1[/tex]
