Answer:
A) Length = 94 m
B) Width = 79 m
Step-by-step explanation:
A)
The area of a parking lot is 7802 m²
Area = length x width
7802 = length x 83
length = 7802 ÷ 83
length = 94 m
b)
The perimeter of a pool is 353 m
Perimeter = 2(length + width)
352 = 2(97 + width)
352 = 194 + 2width
2width = 352 - 194
2width = 158
width = 158/2
width = 79 m

An electronic repair shop offers three types of service: on-site, at-store, and by-mail. On-site service costs 3 times as much as at-store service. By mail service costs $10 less than at-store
service. Last week, the shop completed 15 services on-site, 40 services at-store, and 5 services by mail for total sales of $3100.
Complete ALL parts. SHOW ALL WORK FOR FULL CREDIT
Part A : Define variables for each service. (1 point)
Part B
Write a systems of equations for the services. (3 points)
Part : Determine the cost of one on-site repair service. SHOW ALL WORK! (3 points)
Using a system of equation, we have that:
a)
x, which is the cost of on-site service.y, which is the cost of at-store service.z, which is the cost of by-mail service.b)
The system is:
[tex]x = 3y[/tex]
[tex]z = y - 10[/tex]
[tex]15x + 40y + 5z = 3100[/tex]
c)
The cost of one on-site repair service is of $90.
Item a:
The variables are:
x, which is the cost of on-site service.y, which is the cost of at-store service.z, which is the cost of by-mail service.Item b:
On-site service costs 3 times as much as at-store service, thus:
[tex]x = 3y[/tex]
By mail service costs $10 less than at-store service, thus:
[tex]z = y - 10[/tex]
Last week, the shop completed 15 services on-site, 40 services at-store, and 5 services by mail for total sales of $3100, thus:
[tex]15x + 40y + 5z = 3100[/tex]
The system is:
[tex]x = 3y[/tex]
[tex]z = y - 10[/tex]
[tex]15x + 40y + 5z = 3100[/tex]
Item c:
The cost of one on-site repair service is x.First, replacing the first two equations into the third, we find y, and then with it we find x.[tex]15x + 40y + 5z = 3100[/tex]
[tex]15(4y) + 40y + 5(y - 10) = 3100[/tex]
[tex]60y + 40y + 5y = 3150[/tex]
[tex]105y = 3150[/tex]
[tex]y = \frac{3150}{105}[/tex]
[tex]y = 30[/tex]
Then
[tex]x = 3y = 3(30) = 90[/tex]
The cost of one on-site repair service is of $90.

Convert 3 miles to feet. A. 15,840 feet B. 1,584 feet C. 3,279 feet D. 9,372 feet
Answer:
A. 15,840 feet
Step-by-step explanation:
1 mile = 5,280 feet (I think "five tomatoes" is helpful: five tomatoes --> five-two-eight-oh)
multiply both sides of equation by 3: 1 * 3 = 5,280 * 3
simplify: 3 miles = 15,840 feet, which means A is the answer

Which equation represents the line through (0,0) and (2,5)?
A. y= 5x
B. y= 2x
C. y= 5/2x
D. y= 2/5x
The equation of the line passing through (0,0) and (2,5) will be y = ( 5 / 2 )x. The correct option is C.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line is:-
y = mx + c
Given that the line passes through (0,0) and (2,5). to calculate the equation we need to calculate the slope of the line.
m = ( y₂ - y₁) / ( x₂ - x₁ )
m = ( 5 - 0 ) / ( 2 - 0 )
m = ( 5 / 2 )
y = ( 5 / 2)x + c
0 = 0 + c
c = 0
Y = ( 5 / 2)x
Therefore, the equation of the line passing through (0,0) and (2,5) will be y = ( 5 / 2 )x. The correct option is C.

find the value of a and b when x=12
a = 5x (squared) / 2 = 360
b = 2x (squared) * (x-5) / 10x = ?
Step-by-step explanation:
[tex]a = \frac{ 5{x}^{2} }{2} = 360 \\ b = \frac{2 {x}^{2}( x - 5) }{10x} [/tex]
a =
[tex] \frac{5( {12}^{2} )}{2} = 360 = a \\ \frac{5(144)}{2} = 360 = a \\ 5(72) = 360 = a \\ a = 360[/tex]
b =
[tex]b = \frac{2 {x}^{2} (x - 5)}{10x} \\ b = \frac{x(x - 5)}{5 } \\ b = \frac{ {x}^{2} - 5x}{5} \\ b = \frac{ {12}^{2} - 5(12) }{5} \\ b = \frac{144 - 60}{5} \\ b = \frac{84}{5} \\ b = 16.8[/tex]
The required values are a = 360 and b = 16.8 when x = 12.
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
The numerical expressions are given as:
a = 5x²/ 2 = 360
b = 2x² × (x-5) / 10x
To find the value of a when x = 12, we can substitute 12 for x in the expression for a:
a = 5(12)² / 2 = 360
To find the value of b when x = 12, we can substitute 12 for x in the expression for b:
b = 2(12)² × (12-5) / 10(12)
= 2(144) × 7 / 120
= 288 × 7 / 120
= 2016 / 120
= 16.8
Therefore, when x = 12, a = 360 and b = 16.8.

Rosa’s market sells deli meats by the pound. The prices for several different meats are shown in the table, Chicken=2.00$ Beef=7.00$ Turkey=3.00$ pork=5.00$ how much more does 1 and 1 half pounds of beef cost than 1 and 1 half pounds of turkey
Answer: 1.75 more pounds!
Explanation: Beef: 1 pound is $4.25. now divide $4.25 by 4 to get 1/4 of the price for a pound. then add 1 pound of beef ($4.25) and 1/4 pound of beef ($1.06) which gives you $5.31
Beef: 1 pound is $2.85. now divide $2.85 by 4 to get 1/4 of the price of a pound. then add 1 pound of turkey ($2.85) and 1/4 pound of turkey ($0.71) which gives you $3.56
Now, 1 1/4 pounds of beef and 1 1/4 pounds of turkey subtract them and that gives you $1.75.
Hope that helps!
lets suppose there is a tile which has the following dimensions: 3.6m x 2.4m. if we convert these values into cm then they become 360cm x 240cm which equals 86400cm.But... 3.6m x 2.4m = 8.62m which equals 862cm. I'm pretty sure that I'm making a mistake but I cant find it (probably because I'm sleep deprived).
Answer:
I'm not entirely sure, but I think since you're dealing with area, that changes the way you'd do the math.
Step-by-step explanation:
Since centimeters will have a larger number than meters, that being a number 100x larger, the area is gonna appear a lot bigger. Let's say you have a tile that's 2cm x 4cm with an area of 8cm^2. If you double the sides to 4cm x 8cm, your area will quadruple to 32cm^2.
I think that's what is happening in terms of your problem.

The Pythagorean theorem tells you the relationships of sides in a right triangle is ...
a² + b² = c² . . . . . . where 'a' and 'b' are the legs, and 'c' is the hypotenuse
6² +8² = c²
36 +64 = c² = 100
c = √100 = 10
The length of the hypotenuse is 10.
_____
Additional comment
The ratio of the leg lengths is 8/6 = 4/3. The only right triangle with legs in the ratio 4/3 has the relationship ...
hypotenuse : long leg : short leg = 5 : 4 : 3
If you multiply these numbers by 2, you see they correspond to the side lengths in this triangle. Your familiarity with a 3-4-5 right triangle can let you write down the answer immediately.
