n the card game The Dragons of Castlenook, players score points based on the cards they have at the end of the game. Before playing, Reagan randomly selects 13 cards from the 80-card deck and gets 5 dragons, 1 cyclops, 4 ogres, and 3 centaurs. Based on the data, estimate how many ogre cards are in the deck.
Using proportions, it is found that the estimate of the number of ogre cards in the deck is of 24.6.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, out of 13 cards, 4 are ogres. How many are ogres out of 80? The rule of three is given by:
13 cards - 4 ogres.
80 cards - x ogres.
Applying cross multiplication:
13x = 320.
x = 320/13
x = 24.6.
The estimate of the number of ogre cards in the deck is of 24.6.

Answer:
Step-by-step explanation:
To get how far up the tree that Mr. Jones tied the rope, we will use the Pythagoras theorem since a right angle is created with the rope and the base of the tree.
The length of the rope will be the hypotenuse
The distance up the tree and away from the base will be the opposite and adjacent.
Given
length of the rope = 8feet
Distance away from the base of the tree = 6ft
According to Pythagoras;
hyp² = opp²+adj²
8² = opp²+6²
opp² = 8²-6²
opp² = 64-36
opp² = 28
opp = 5.3 feet
Hence the Mr Jones tied the rope 5.3feet above the tree. Option C is correct

A segment has one endpoint at the origin O and the other endpoint at A(12,36). If point B is located on OA such that OA/BA=3 then which of the following are the coordinates of B?
(1) (4,12) (2) (9,27) (3) (8,24) (4) (36,108)
The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).
How to find the coordinates of point B?We know that:
O = (0, 0)A = (12, 36).And point B is between these two, such that:
OA/BA = 3
Meaning, OA is 3 times BA.
Now, if we apply a factor of 1/3 to point A, we get:
(12/3, 36/3) = (4, 12)
So, the distance between A and B is equal to the distance between the origin and (4, 12) (a change of 4 units in the x-component and 12 units in the y-component).
The point that meets that condition is (8, 24), which is given by multiplying by 2 the previous coordinates.
The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

Tom walks 3. 15 km to the park. He then walks a further 350 m to the shop. How many km has Tom walked in total?
Answer:
Step-by-step explanation:
We have to convert m to km and we have to add to find the total distance walked.
1000m = 1 km
350 m = 350 ÷ 1000 = 0.35 km
Total distance = 3.15 + 0.35
= 3.50 km

Slopes step by step
Answer:
1 is y=-1/3x. 3 is y=-3/2x. 5 is y=5/3x
Step-by-step explanation:
Simply count the vertical lengths. Meaning count up or down how ever many. That is your top number. Then count your horizontal lengths, meaning left or right, this your bottom number of the slope. So if point A is at (-1,-1) in example 1, then count down 1, and right 3 spaces. Because you go down, the slope is negative, and you went down 1, so the top number is 1, you went right 3 units, so the bottom number is 3.

Solve the inequality b - 12 > -3
What are the solutions?
Answer:
b>9
Step-by-step explanation:
Answer:
b > 9
Step-by-step explanation:
Inequalities represent the value of a variable in relation to other numbers.
Solving the Inequality
The properties of equality state that if you add or subtract a number from both sides, the statement remains true. This means that we can isolate the variable by using the properties of equality.
To isolate the variable, add 12 to both sidesThis gives the inequality b > 9Understanding the Answer
The answer to the inequality is b > 9. This means that the variable must be greater than 9. So, values such as 10 or 100 could all be solutions. However, remember that 9 itself is not a solution. The inequality only accounts for values greater than 9, not equal to.
A store sells two brands of applesauce.
Which brand provides more servings?
brand A: 24 1/2 ounces 2/3 cup per serving
brand B: 30 2/3 ounces 3/4 cup per serving
Alternative text
A.
Brand A because it provides 4 19/32 servings.
B.
Brand A because it provides 16 1/3 servings.
C.
Brand B because it provides 5 1/9 servings.
D.
Brand B because it provides 23 servings.
This problem is a dog of a bear because of the units.
It tells us how many ounces are in a jar, but how many cups are in a serving.
So in order to figure out how many servings are in a jar, we have to either change the jar from ounces to cups, or else change the serving from cups to ounces.
And of course, in order to do either of those things, we need to know how many ounces make 1 cup ! Hint: 1 cup = 8 ounces .
AND PLUS trying to work with all the fractions is gonna be ridiculous too.
Jar-A: (24 1/2 ounces) / (8 ounces/cup) = 3 1/16 cups
How many servings is that ?
(3 1/16 cups) / (2/3 cup/serving) = 4 19/32 servings
Jar-B: (30 2/3 ounces) / (8 ounces/cup) = 3 5/6 cups
How many servings is that ?
(3 5/6 cups) / (3/4 cup/serving) = 5 1/9 servings
(5 1/9) is more than (4 19/32). So Jar-B provides more servings than Jar-A.
Choice - C
Note: Both brands are great for people who are on a diet, because they have to work off so many calories working out the stupid fractions, and it takes so long that they never get around to eating the applesauce.
Answer:
ar-B provides more servings than Jar-A. Choice - C

what's better 27 out of 32 or 19 out of 21 and why
Answer:
19/21 is better.
Step-by-step explanation:
To find which is better, you need to divide the numerator by the denominator.
27 divided by 32 is equal to 0.84375
19 divided by 21 is equal to 0.9
0.9 is greater than 0.84375, so 19/21 is better.
