he length of a rectangle is five times its width.
If the perimeter of the rectangle is 120m , find its length and width.
Answer:
w = 10
l = 50
Step-by-step explanation:
Formula of Perimeter: w + w + l + l or 2w + 2l
l = 5w
2l + 2w = 120
2(5w) + 2w = 120
10w + 2w = 120
12w = 120
w = 10
l = 5(10)
l = 50
Check:
2l + 2w = 120
2(50) + 2(10) = 120
100 + 20 = 120
120 = 120
Hope This Helps!
Lets denote our variables as:
x the width of the rectangle5x the length of the rectangleThe formula for the perimeter of a rectangle is P = 2L + 2W, where L is the length of the rectangle and W is the width of the rectangle. We know that the perimeter of the rectangle is 120m, so we can write:
2(x) + 2(5x) = 120
2x + 10x = 120
12x = 120
x = 120/12
x = 10 m → Width of the rectangle
Substituting in the length:
5x = 5(10) = 50 m → Length of the rectangle
The length of the rectangle is 50 m and its width is 10 m.

A pie company randomly surveys 60 customers to determine which type of pie they would purchase.
The results of the survey are shown.
Favorite Type of Pie
Peach
25%
Apple
331%
Other
20%
Cherry
The company expects to sell 65 cherry pies in March.
Based on the survey results, how many whole peach pies should the company expect to sell in March?
Answer:
Explained below.
Step-by-step explanation:
Construct the frequency distribution from the percentage distribution as follows:
Favorite Type of Pie Percentage Frequency
Peach 25% 25% of 60 = 15
Apple 31% 31% of 60 = 18.6
Other 20% 20% of 60 = 12
Cherry 24% 24% of 60 = 14.4
TOTAL 100% 60
It is provided that the company expects to sell 65 cherry pies in March.
The total number of people buying pies is:
[tex]\#\text{People buying Cherry pies}=\#\text{People buying pies}\times 0.24\\\\\#\text{People buying pies}=\frac{65}{0.24}\\\\\#\text{People buying pies}=270.833[/tex]
Now compute the number of peach pies should the company expect to sell in March as follows:
[tex]\#\text{Peach pies expected to be sold}=270.833\times 0.25 =67.7\approx 68[/tex]
A T-shirt design company charges your team an initial fee of $25 to
create the team's design. Each t-shirt printed with your design costs an
additional $8. How much does it cost you to buy 10 shirts? **Don't forget
the initial fee.**(hint: determine the equation first y = _X + __ and then
plug in 10 for x)
Answer
$305 hope this helps!!! :)
Step-by-step explanation:
(A)
Let [tex]x[/tex] be the number of T-Shirts and [tex]y[/tex] be the total costs so that the total cost is:
Total Cost= $25+ $8 times the number of T-Shirts
(B) [tex]y=25+8x[/tex]
For 35 members we need 35 T-Shirts so using the Linear model from part (A) substitute [tex]x[/tex] to 35 and solve for [tex]y[/tex]:
[tex]y=25+8(35)[/tex]
[tex]y=25+280[/tex]

An item has listed price of $70. If the sales tax rate is 9%, how much is the sales tax (in dollars)
Answer:
The final sales tax price is $6.30.
Step-by-step explanation:
We know that the item has a listed price of $70, and it also has a 9% sales tax rate. In order to calculate this amount we need to do some multiplying.
$70 is the full amount of money, or 100%, plus 9% is 109%. To calculate the sales tax, we need to multiply the listed price by the sales tax rate.
70 x 1.09 = 76.3
Now, we must subtract the listed price (or $70), by the sales tax price (or $76.30)
76.3 - 70 = $6.30
Therefore, the final price of the sales tax is $6.30.

Juliet needs to rewrite 3 (x + 2) = 6 y in slope-intercept form so she can easily graph it. Which step would be correct to start the process?
A. She could combine the x and 2 to get 3 (2 x) = 6 y.
B. She could divide both sides by 3 to get x + 2 = 2 y.
C. She could distribute the 3 to get 3 x + 2 = 6 y.
D. She could subtract the 6y to get Negative 6 y = 3 (x + 2).
Answer:
because the x+2 is in parentheses, to put the equation in slope intercept form you would distribute the 3 to the x and the 2 using multiplication. So it would be 3x+6=6y. The final result would be y=1/2x+1.
Answer:
C. She could distribute the 3 to get 3 x + 2 = 6 y.

What number should go in the empty boxes to complete the calculation for finding the product of 0.63 × 0.24? 0.63 times 0.24 equals box 52 plus 1 box 60 equals 0.1512 (Hint: it is the same number. Input only one number in the blank.) (3 points) Blank 1:
Answer:
The number is 2
Step-by-step explanation:
0.63
× 0.24
= 252
+1260
=0.1512
step 1
The place value of 4 in one 0.24 is hundredth. Using 4-hundredth to multiply 063 gives 252
The place value of 2 in 0.24 is tenth
Using 2-tenth to multiply 063 gives 1260
Hence, 0.63 times 0.24 equals 252 plus 1260 equals 1.512

Step-by-step explanation:
subtracting 1 from the product of 5 and x gives the same value as adding 10 to the product of 3 and x
Answer:
x = 11/2
Step-by-step explanation:
We would first put it in an equation
5x - 1 = 10 + 3x
We would first add 1 on both sides
5x = 11 + 3x
Then we subtract 3x on both sides
2x = 11
Divide both sides by 2
x = 11/2
The value of x from the given algebraic statement expression is;
x = 11/2
This is about simple Algebra.
The first expression is that; We are to subtract 1 from the product of 5 and x. This give; 5x - 1The second expression is that we are to add 10 to the product of 3 and x. This gives us; 3x + 10Finally, we are told that the first expression gives the same value as the second expression. This means that they are equal to each other and as such, we have;
5x - 1 = 3x + 10
Let's add 1 to both sides to get;
5x - 1 + 1 = 3x + 10 + 1
⇒ 5x = 3x + 11
Let's subtract 3x from both sides to get;
2x = 11
Divide both sides by 2 to get;
x = 11/2

Marian se deplaseaza ,cu automobilul,pe autostrada.La ora 10 si 35 minute el se afla la kilometrul 25 .Dupa un interval de timp,la ora 11 si 15 minute,el se afla la kilometrul 100.Calculati :durata deplasarii,distanta parcursa de Marian si viteza medie a acestuia(exprimata in unitati de SI)
Step-by-step explanation:
If Marian travels, by car, on the highway. At 10 and 35 minutes he is at kilometer 25. After a period of time, at 11 and 15 minutes, he is at kilometer 100.
Total distance covered = 25km + 100km
Total distance covered by Marian = 125km
Total time taken by marian = 10hr 35min + 11hr + 15min
Total time taken by marian = (10+11)hr + (35+15)min
Total time taken by marian = 21hr 50mins
Total time taken by marian = 21 * 50/60 hr
Total time taken by marian (Duration) = 21.833hr
Average speed = Total distance covered/Total time taken
Average speed = 125/21.833
Average speed = 5.725km/hr
Convert to m/s
5.725km/hr = 5.725*1000/3600
5.725km/hr = 5725/3600
5.725km/hr = 1.5903 m/s
Hence the average speed expressed in SI unit is 1.5903 m/s
