What is the actual width, w, of the island if the width in the drawing is 2.5 inches?
Convince Me!
How would the proportion for Example 1, 1.5/1 = x/6, change if the scale changed?
The actual width, w, of the island is 22.5 inches if the width in the drawing is 2.5 inches.
How can we determine the actual width using a scale factor?
The actual width can be determined by multiplying the width with the scale factor.
Given that:
[tex]\mathbf{\dfrac{1.5}{1}=\dfrac{x}{6}}[/tex]
[tex]\mathbf{\dfrac{1.5}{1} \times 6=x}[/tex]
x = 9
If the width of the drawing is 2.5 inches, the actual width of the island is:
= scale factor × width of the drawing
= 9 × 2.5 inches
= 22.5 inches.

Riddle: If a hen and a half lays an egg and a half, in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?
Please explain the answer!
Answer:
2 dozen or 24.
The number of hens was increased from 1.5 to 6 (4 times more) and the number of days was increased from 1.5 to 6 (also 4 times more). The effect is cumulative, thus the amount of eggs that will be layed will be 16 times more (i.e. 24 instead of 1.5).

Answer:
11 soccer balls (rounded estimate; should be close to 11)
Step-by-step explanation:
Because you need to match the limit, you first have to convert in. to ft. That will get you at 2.3 (it is an non-stopping number, so I rounded to the tenths). 11 x 2.3 is 25.3. You can’t go lower, so you have to have that extra soccer ball. Hope this helps.

Answer:
C
Step-by-step explanation:
Mean is all the numbers in the list added / the number of numbers
(Ex: 14, 13, 15, 17
Mean = (13 + 14 + 15 + 17) / (number of numbers in the list)
Mean = 59 / 4
Mean = 14.75)
Range = (The largest number - the smallest number)
Mode is the number that appears the most
The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number

Mean of Ernie = 19
Mean of Lori = 17.6
A is False
Range of Ernie = 7
Range of Lori = 8
B is false
Median of Ernie = 18
Median of Lori = 18
C is true
Mode of Ernie = 17
Mode of Lori = 18

Answer:
5√15
Step-by-step explanation:
(√3 + √48)(√20 - √5)
step 1 simplify √48
(√3 + 4√3)(√20 - √5)
step 2 add √3 and 4√3
(5√3)(√20 - √5)
step 3 simplify √20
(5√3)(2√5 - √5)
step 4 subtract √5 from 2√5
(5√3)(√5)
step 5 multiply 5√3 and √5
= 5√15
explanation of each step
step 1 and 3
To simplify radicals you list the factors of the number under the sqaure root
For 48 we have 2 × 2 × 2 × 2 × 3
We then pair the factors off as powers of 2 if possible
We get 2² × 2² × 3 which can further be simplified as 4² × 3
We then list the number with the power on the outside of the radical and leave the numbers with no power on the inside to get 4√3.
This process is used to simplify √20 as well.
step 2 and 4
For these two steps we are adding and subtracting radicals with the same radicand ( number inside of the square root. ) This is very simply as we keep the radicand the same and just perform the operation to the coeffecients ( number on the outside of the square root )
Eg. a√b + c√b = (a+c)√b or a√b - c√b = (a-c)√b
Hence, 4√3 + √3 = (4+1)√3 = 5√3
Step 5.
Finally we multiply the two radicals. This is very simply as we can use the rule to do so.
a√b × c√d = (a×c)√b×d
Hence, 5√3 × √5 = (5×1)√(3×5) = 5√15

3(6f+8)
Answer:
first of all what you have to do is to use a method called distribute property when you see this type of questions and multiply for example 3 times 6f and getting an answer of 18f and then finally you just multiply 3 times 8 and the answer is 24 so basically the answer should be 18f+24 and hope this helps and can you also tell me the answer choices and if it was correct or not and thanks for helping you.
Step-by-step explanation:
Answer:
18f+24
Step-by-step explanation:
Use the Distributive Property of Multiplication...
3 x 6f = 18f (note; when multiplying a number by a veriable, just add the variable to the product).
3 x 8 = 24
answer: 18f+24
Basketball tickets were $5 for the floor seats and $2 for the grandstand seats
If 210 people attended and paid $660, how many people bought floor seats?
Answer:
Good seats sold=80
Poor seats sold=130
Step-by-step explanation:
g + p = 210 seats. Then p = 210 - g.
($5)g + ($2)p = $660. Substite 210 - g for p,
($5)g + ($2)(210 - g) = $660
Simplify, 5g + 420 - 2g = 660 => 3g = 240 => g = 80
80 and 130
