Answer:
The equation is;
3(x + 0.75) = 5.88
The original price is $1.21
Step-by-step explanation:
Let the original price per pound be $x
By going up, the new price will be;
(x + 0.75)
3 times this is the new price;
3(x + 0.75) = 5.88
3x + 2.25 = 5.88
3x = 3.63
x = 3.63/3
x = $1.21

Evaluate the exponential expression. 14^2
Answer:196
Step-by-step explanation:
Answer:
196
Step-by-step explanation:
Exponential expressions are just a way to write powers in short form. The exponent indicates the number of times the base is used as a factor. So in the case of 32, it can be written as 2 × 2 × 2 × 2 × 2=25, where 2 is the “base” and 5 is the “exponent”. We read this expression as “two to the fifth power”.

A plumber charges $75 for the service call and $25 per hour (h) for repairs. Write an algebraic expression to represent the total bill for all plumbing services.
A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Hi! The answer to your question is [tex]\sqrt{5}[/tex]
Step-by-step explanation:
Use the Distance Formula to determine the distance between two points.
- Brooklynn Deka

Find the distance between (-1,-2) and (8,9)
Answer:
[tex]\sqrt{202}[/tex] units or 14.2 units (rounded to the nearest tenth)
Step-by-step explanation:
To find the distance between a pair of two points, use the distance formula [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:
[tex]d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}[/tex]
So, as an exact answer, the distance is [tex]\sqrt{202}[/tex] units.
(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)
Answer:
14.2
Step-by-step explanation:
All you need to do is plug the coordinates into the distance formula.
√(x2 - x1)² + (y2 - y1)²
√[8 - (-1)]² + [9 - (-2)]²
√(9)² + (11)²
√81 + 121
√202
= 14.2

Answer:
a = 14
Step-by-step explanation:
The consecutive angles in a parallelogram are supplementary, sum to 180°
a² - 10a + 7a + 26 = 180
a² - 3a + 26 = 180 ( subtract 180 from both sides )
a² - 3a - 154 = 0 ← in standard form
(a - 14)(a + 11) = 0 ← in factored form
Equate each factor to zero and solve for a
a - 14 = 0 ⇒ a = 14
a + 11 = 0 ⇒ a = - 11
Since a > 0 , then a = 14

Which is a different way to express 5r?
5+r
2r+3r
r5
3r⋅2r
Answer:
2r+3r
Step-by-step explanation:
even though r5 looks correct, you always have to put the varible on the right side of a number. 2r+3r is correct because if you combine like terms, you get 5r

A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 of its 600 members. What is the population of this study? The population is all 50 members of the health club. The population is all 600 and 50 members of the health club. The population is all 600 members of the health club. The population is all 30,000 members of the health club.
Answer:
The population is all 600 members of the health club
Explanation:
50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

The diagram shows the front face of a barn,
The width of the barn is 12 m.
The height of the barn is 8m.
The sides of the barn are both of height 5m.
Work out the area of the front face of the barn.
Answer:
the front face of the barn: 78m^2
Step-by-step explanation:
look at the photo
The area of a 2D form is the amount of space within its perimeter. The area of the front face of the barn is 78 m².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The diagram of the barn can be made as shown below. Therefore, the area of the front face of the barn is,
Area of the barn front = Area of the triangle + Area of the rectangle
= (5 × 12) + (0.5 × 3 × 12)
= 60 m² + 18 m²
= 78 m²
Hence, the area of the front face of the barn is 78 m².
