Answer:
[tex](a)\ y = 2x[/tex]
[tex](b)\ x= 12[/tex]
Step-by-step explanation:
Given
[tex]rose = \$2[/tex]
Solving (a): The equation
Let
y = total amount
x = number of roses
So:
If [tex]x = 1, y = 2[/tex]
If x = x.
[tex]y = 2* x[/tex]
[tex]y = 2x[/tex]
Solving (a): Number of roses for $24
This implies that
[tex]y = 24[/tex]
So:
[tex]y = 2x[/tex]
[tex]24 = 2x[/tex]
Divide both sides by 2
[tex]12 = x[/tex]
[tex]x = 12[/tex]

A store sells jump ropes. Each jump rope costs the same amount. During a sale, the store reduces the price of each jump rope by $1.25. Jada
spends $15.08 on 2 jump ropes at the sale price.
What was the price of 1 jump rope before the sale? Enter the answer in the box.
Answer:
The jump rope cost $8.79 before the sale.
Step-by-step explanation:
She spent 15.08 on 2 while they were on sale. I divided 15.08 by 2 to find what each one cost individually on sale, which is $7.54. Then add $1.25 to $7.54= $8.79

Answer:
43.96
Step-by-step explanation:
14 x 3.14 = 43.96
7 is the radius but 14 is the like line and to find it you add 7 plus 7 (aka the other half) and multiply it by 3.14 thus the answer is
43.96
Answer:
B
Step-by-step explanation:
C = d x pi
Since the radius is half of the diameter, we have to multiply 7 and 2 which would give us 14. After that, we multiply 14 and 3.14 which gives us 43.96 in.

How many 4 digit multiples can not be divided by 5
Answer:
1800
Step-by-step explanation:
Let us solve this question by Modular Airthmatic.
Let the lowest 4 digit number be X.
X= 1 (mod 5)
X =2 (mod 5)
X=3 (mod 5)
X =4 (mod 5)
X=1+5 t where t is any integer.
1+5 t=2 (mod 5)
5 t=1 (mod 5 )
5 is the Modular Inverse of modulo 5
t=1 (mod 5)
t =1+5 u : u= any integer.
X becomes 1+ 5 (1+5u )=6+25 u
6+25u =3 (mod 5)
25 u= -3 (mod 5)=2 (mod 5)
25 is Modular Inverse of Modulo 5
u=2 (mod 5)
u =2+5 v : v= any integer.
X becomes 6 +25 (2+5 v)=56+125 v .
56 +125 v=4 (mod 5)
125 v=-52 (mod 5)=3 (mod 5)
125 is Modular Inverse of modulo 5
v = 3 (mod 5)
v =3 +5 w where w is any integer.
For lowest 4 digit number, take
w=200
X=1003 : Lowest 4 digit number.
Take w=201
X=208 : Next number.
For 4 digit largest number, take
w=1995
X= 9978 : Largest number.
No. of Numbers =(1995 - 200 )+1=1800 □Ans.

Suppose the pet food company's strategy is to increase the proportion of sales orders from new stores in each region to 25% during the coming year. Consider the data and proportions of sales from new stores for each region in the first month. Do you think additional training is necessary for all of the sales representatives?
Answer:Every year, a pet food company sells its food to stores across the nation. ... In the first month of the new year, the Midwest region secured sales orders from ... Suppose the strategy of the pet food company is to increase the proportion of ... Do you think additional field training is necessary for all of the sales representatives?
Step-by-step explanation:
Yes sales representatives in Midwest and Northeast require more training
Although your question is incomplete attached below is the missing data related to your question
Given that the percentage of new stores in the Midwest and Northeast is below the 25% there will be need for an additional training for the sales representatives in these regions. while the percentage of new stores in the south is above 25% hence there won't be the need for additional sales representative training.
Percentage of new stores for after 1 month
Midwest = ( 66 / 362 ) * 100 = 18.2%
South = ( 115 / 197 ) * 100 = 58.3%
North east = ( 60 / 250 ) * 100 = 24%
Hence we can conclude that to meet up the 25% sales orders from new stores in each region additional training is required for sales representative s in Midwest and North east only.

segment EH and segment E prime H prime both pass through the center of dilation.
The slope of segment EF is the same as the slope of segment E prime H prime.
segment E prime G prime will overlap segment EG.

Given triangle EFG:
E(0, 5), F(1, 1), G(-2, 1)Center of dilation is H(0, 1)Scale factor is k = 3The rule for this dilation is:

A boat moving at a constant rate will travel 26 miles in 2 hours. If the boat maintains this rate, how many miles will the boat travel in 5 hours?
Given:
A boat moving at a constant rate will travel 26 miles in 2 hours.
To find:
The distance that will the boat travel in 5 hours.
Solution:
It is given that,
The distance traveled by the boat in 2 hours = 26 miles
The distance traveled by the boat in 1 hour = [tex]\dfrac{26}{2}[/tex] miles
= [tex]13[/tex] miles
The distance traveled by the boat in 5 hour = [tex]5\times 13[/tex] miles
= [tex]65[/tex] miles
Therefore, the boat will travel 65 miles in 5 hours.
Dave is adding a new patio to the back of his house. The dimensions of the patio are shown below. If one bag of concrete mix will cover 50 square feet, how many bags of concrete will he need?
Answer:
Hence for a patio with Dimension
Length=12.5 feet
Width=9.5 feet
2.4 bags of concrete mix is needed
Step-by-step explanation:
The question is not complete, there is not attachment showing the dimension of the patio
Say the dimension of the patio is
Length=12.5 feet
Width=9.5 feet
Area= Length* Width
Area= 12.5*9.5
Area= 118.75 square feet
One bag of concrete mix will cover 50 square feet
Hence x bags will cover 118.75 square feet
cross multiply
50x= 118.75*1
x= 118.75/50
x= 2.4 bags
Find the 19th term of the sequence 5, 8, 11, 14, 17...
59
51
53
56
Answer:
59
Step-by-step explanation:
So, lets look at our numbers in the sequence. So it goes 5 to 8, 8 to 11, 11 to 14, and 14 to 17. This seems like a change in three. So the every 1 term changes the orginal 5 value by 3.
So wouldnt this mean we can multiply the change in terms by the amount of terms? Which is 19*3? Well, sort of. This is the right way of doig this, but we must remember that we already know the first term, 5. So this means we will be doing 18*3.
This gets you 54. Now just add the amount of the 18 terms onto the first term:
54+5
=
59
So your answer is 59.
Hope this helps!

Find the equation of the circle whose center and radius are given.
center ( -2, -5), radius = 1
Answer:
(x + 2)^2 + (y + 5)^2 = 1
Step-by-step explanation:
Since this circle is centered at (-2, -5), we have to add values within the squares. The standard form of a circle equation is:
(x - h)^2 + (y - k)^2 = r^2
So -2 is h and -5 is k. Substituting that in we get:
(x + 2)^2 + (y + 5)^2 = r^2
We are given the radius is 1, and one squared is one, so the final equation is:
(x + 2)^2 + (y + 5)^2 = 1

Answer:
13.125 in³
Step-by-step explanation:
So first convert all the numbers to decimal form. 3/2 converts to 1.5. 7/2 converts to 3.5. 5/2 converts to 2.5.
Now for the actual math. Take 1.5×3.5=5.25. Then take your new number and multiply it by 2.5. 5.25×2.5=13.125.
