Answer:

The distance from Cleveland to Cincinnati on the second map is 8 cm.

Step-by-step explanation:

The distance from Cleveland to Cincinnati is 40 cm on the first map and the scale on the first map is 1 cm to 10 km.

So, the actual distance from Cleveland to Cincinnati [tex]=(40*10) km = 400 km[/tex]

Suppose, the distance from Cleveland to Cincinnati on the second map is  [tex]d[/tex] cm.

Given that, the scale on the second map is 1 cm to 50 km. So, the equation will be........

[tex]\frac{d}{400}=\frac{1}{50}\\ \\ 50d=400\\ \\ d=\frac{400}{50}=8[/tex]

So, the distance from Cleveland to Cincinnati on the second map is 8 cm.

The distance from Cleveland to Cincinnati on the second map can be found to be 8 cm.

To find the actual distance from Cleveland to Cincinnati, you would multiply the map distance by the scale:

= 40 cm * 10 km/cm

= 400 km

So, the actual distance from Cleveland to Cincinnati is 400 km.

Now, on the second map, the scale is 1 cm to 50 km.

To find the distance from Cleveland to Cincinnati on the second map, you would divide the actual distance by the scale of the second map:

= 400 km / 50 km/cm

= 8 cm

So, the distance from Cleveland to Cincinnati on the second map would be 8 cm.

Answer:

60 hummingbirds can be fed by a 12 ounce feeder.

Step-by-step explanation:

In order to solve this problem, we can make a ratio table. For every 16 ounce feeder, 80 hummingbirds can be fed. However, we want to calculate how many hummingbirds can be fed by a 12 ounce feeder. We can get a common denominator for our ratio to solve this. 16:80 divided by 4:4 is 4:20. Since 4 is a factor of 12, we can multiply 4 by 3 to get 12. However, what we do to one section we do to the other. 20 x 3 is 60. 60 hummingbirds can be fed by a 12 ounce feeder.

3/4x + 3 = 5/6

(3/4 * 12)x + 3 = (5/6 * 12)

9x + 3 = 10

You have to find the lowest common denominator (LCD) by finding the number that you can multiply into every fraction to turn them into a whole number.

Converting a power into an equivalent multiplication expression involves rewriting the power's base and exponent using multiplication. The exponent signifies how many times to multiply the base by itself.

Converting a power into an equivalent multiplication expression with two factors involves rewriting the power's base and exponent. Consider, for example, a power like 6^3. This expression can be rewritten as multiplication with two factors in different ways, such as 6 x 6 x 6 or 36 x 6. The exponent value tells us how many times to multiply the base by itself. Remember that this is true for all types of powers, including whole numbers, negative numbers, and fractions, which means your multiplication expression factors may differ.

The riddle compares a lame elephant to the act of adding 19 and 4, where the answer lies in the wordplay of 'one-legged' (1+9+4) and 'too-free' (sounding like 23).

The question "Why is a lame elephant like adding 19 and 4?" appears to be a playful riddle rather than a straightforward math problem.

The answer to this riddle plays on the similarity in sound between the words 'lame' and the number '1' when saying 'one-legged' or '1-legged', as well as the sum of the numbers 19 and 4 being 23, which can sound like 'two' and 'three' or 'too-free' when spoken quickly.

To conclude, a lame elephant is like adding 19 and 4 because it is 'one legged' or could be jokingly considered 'too-free' to walk as it would if it weren't lame.

Answer:

q = 0

Step-by-step explanation:

Solving the given Equation for q : 3 + q + 9 = 12 we get Option (b) q = 6

In the given equation, 3 + q + 9 = 12, we need to solve for q. To do this, we first combine the constants on the left side of the equation: 3 + 9 = 12. This simplifies to 12 = 12. Now, our equation becomes q + 12 = 12.

Next, we want to isolate q on one side of the equation. To do this, we can subtract 12 from both sides: q + 12 - 12 = 12 - 12. This simplifies to q = 0.

However, we must be cautious. While q = 0 satisfies the original equation of 3 + q + 9 = 12, it does not satisfy the intermediate equation q + 12 = 12. In fact, any value of q will satisfy the intermediate equation since adding 0 to any number does not change its value.

Let's verify the other answer choices:

(a) q = 0: As we just discussed, q = 0 satisfies the intermediate equation but not the original equation.

(c) q = 18: If we substitute q = 18 into the original equation, we get 3 + 18 + 9 = 30, which is not equal to 12.

(d) q = 24: If we substitute q = 24 into the original equation, we get 3 + 24 + 9 = 36, which is not equal to 12.

Therefore, the correct answer is (b) q = 6, as q = 6 satisfies both the intermediate equation (6 + 12 = 12) and the original equation (3 + 6 + 9 = 12).

In summary, the correct value of q that satisfies the given equation is 6.

Answer:

86

Step-by-step explanation:

The pattern follows this rule:

Every time, the difference between current term and the succeeding term is 0.5 more than that of the current term and preceding term.

The difference between the current term and the preceding term is:

89.5 - 92.5 = 3

Hence, the next term of the sequence should be 3.5 less than the current term.

Hence, the next term is 89.5 - 3.5 = 86.

Answer:  The required length and breadth of the rug are 46 yards and 189 yards respectively.

Step-by-step explanation:  Given that a rectangular rug has a perimeter of 470 yards. The width of the rug is 5 yards more than four times the length.

We are to find the length and width of the rug.

Let l represents the length of the rug. Then, the width of the rug will be

[tex]w=4l+5.[/tex]

According to the given information, we have

[tex]470=2l+2w\\\\\Rightarrow 470=2l+2(4l+5)\\\\\Rightarrow 470=2l+8l+10\\\\\Rightarrow 10l=460\\\\\Rightarrow l=\dfrac{460}{10}\\\\\Rightarrow l=46.[/tex]

So, the width is given by

[tex]w=4\times46+5=184+5=189.[/tex]

Thus, the required length and breadth of the rug are 46 yards and 189 yards respectively.

10x + 2y > 20

Solution

Step 1: First we have to rewrite the given equation y in terms of x.

Subtract 10 x from both sides, we get

10x - 10x + 2y > -10x + 20

2y > -10x + 20

Divide both sides by 2, we get

y > -5x + 10

Step 2: Now we have to find the coordinates by plugging in the values of for x = -1, 0, 1

and  find the corresponding values for y.

Plug in x = -1,

y = -5(-1) + 10 = 5 + 10 = 15.

The coordinates are (-1, 15)

Plug in x = 0, we get

y = -5(0) +10 = 10

The coordinates are (0, 10)

Plug in x = 1, we get

y = -5(1) + 10 = -5 +10 = 5

The coordinates are (1, 5)

Step 3: Now plot the points on a grid and draw the draw the dotted line because it is greater than. Since it is grater than we have to shaded the region above the line.

Answer:

The mark up is $21.16 and the final selling price is $44.14

Step-by-step explanation:

To find the mark up price, you simply multiply the cost by the mark up percentage. This will give you the mark up.

$23 * 92% = $21.16

Now to find the total selling price, we add the cost and the mark up together.

$23 + $21.16 = $44.16

Final answer:

The amount of markup on the Algebra 1 book is $21.16, calculated by multiplying the wholesale price of $23 by the markup percentage of 92%. The selling price of the book is $44.16, the sum of the wholesale price and the markup.

Explanation:

To calculate the amount of the markup for the Algebra 1 books, we will apply a percentage increase to the wholesale price. The wholesale price of each book is $23, and the markup percentage is 92%. To find the markup amount, we multiply the wholesale price by the markup percentage:

Markup = wholesale price × Markup percentage

Markup = $23 × 0.92
Markup = $21.16

Now, to calculate the selling price, we add the markup to the wholesale price:

Selling Price = Wholesale Price + Markup
Selling Price = $23 + $21.16
Selling Price = $44.16

Therefore, the amount of the markup is $21.16, and the selling price of the book is $44.16.

lily get 3 /(4+3)

she get 3/7

Final answer:

Lily receives 3/7 of the total money when it is shared in a 4:3 ratio with Annie.

Explanation:

If Annie and Lily share some money in the ratio of 4:3, we can use this ratio to determine what fraction of the money Lily gets. The total parts of the ratio are 4 (for Annie) plus 3 (for Lily), which equals 7 parts in total.

Lily's share is 3 parts of the total 7 parts. So, Lily receives 3/7 of the total money. This fraction represents Lily's portion when the money is divided according to the given ratio.
