Absolute value represents the distance from zero when graphed on a number line. For example, the number 7 is 7 units away from zero. ... A number and its additive inverse are always the same distance from zero, and so they have the same absolute value.

Using proportions, it is found that the estimate of the number of ogre cards in the deck is of 24.6.

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:

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.

Answer:

[tex](x + 4)(x + 5)[/tex]

[tex]x \times x + 5x + 4x + 4 \times 5[/tex]

[tex]x {}^{2} + 5x + 4x + 20[/tex]

[tex]x {}^{2} + 9x + 20[/tex]

The standard form of the expression (x+4)(x+5) is  x²+9x+20.

An expression is combination of variables, numbers and operators.

The given expression is (x+4)(x+5)

x is the variable in the given expression.

We have to multiply and simplify the expression.

Let split the expression as below.

x(x+5)+4(x+5)

Apply the distributive property

x²+5x+4x+20

Combine the like terms

x²+9x+20

x²+9x+20 is the standard form of the expression (x+4)(x+5)

Hence, the standard form of the expression (x+4)(x+5) is  x²+9x+20.

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

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

The distance between (8, 24) and (12, 36) is one-third of the distance between (0, 0) and (12, 36).

We know that:

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).

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

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.
