Amita's kitchen is rectangular with an area of 3 3 4 square meters. The width of the kitchen is 1 1 2 meters. What is the length, in meters, of Amita's kitchen?
Answer:
2 1/2 meters
Step-by-step explanation:
Amita's kitchen is rectangular with an area of 3 3 /4 square meters. The width of the kitchen is 1 1/ 2 meters. What is the length, in meters, of Amita's kitchen?
The formula for the area of a rectangle = Length × Width.
To find the length our formula becomes : Area/Width
In the question,
Area = 3 3/4 m²
Width = 1 1/2 m
Length of the rectangular kitchen
= 3 3/4 m² ÷ 1 1/2 m
= 15/4 m² ÷ 3/2 m
= 15/4 m² × 2/3 m
= 5/2 m
= 2 1/2 m
The length of the rectangular kitchen is 2 1/2 meters

What is the equation in point-slope form of the line that passes through the point (4,-5) and has a slope of 2/3?
Answer: I believe the correct answer is the last one but I’m not entirely sure, wait for someone else to answer.
Step-by-step explanation:
Answer:
third one
Step-by-step explanation:
point-slope form is y - y1 = m(x - x1)
plug in values y -(-5) = 2/3(x - 4)
the double negative cancels out and becomes a positive
therefore y + 5 = 2/3(x - 4)
Solve 10=5m/4
Im Confused, Please Help
Answer:
m = 8
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define
10 = 5m/4
Step 2: Solve for m
Multiply 4 on both sides: 40 = 5mDivide 5 on both sides: 8 = mRewrite: m = 8Step 3: Check
Plug in m into the original equation to verify it's a solution.
Substitute in m: 10 = 5(8)/4Multiply: 10 = 40/4Divide: 10 = 10Here we see that 10 does indeed equal 10.
∴ m = 8 is the solution to the equation.
a plane has fees for 420 passengers 15% of the seats are empty how many passengers are on the plane
Answer:
357 passengers
Step-by-step explanation:
[tex]\frac{x}{420}=\frac{85}{100}[/tex] (The [tex]\frac{85}{100}[/tex] is 85% of the 100% people because 15% is missing)
When you cross-simplify you get: [tex]\frac{x}{21}=\frac{85}{5}[/tex] which is [tex]\frac{x}{21}=17[/tex]
Finally, multiply 17 by 21 to get x.
Therefore, x=357
5. If your friend's doctor wants her target heart rate range to be between 143 and 170, and her
average resting heart rate is 62, what is her age? How did you backtrack through these equations
to find her age?
Fast please
Answer:
a person can work out 50% of the maximum (50% of 194 is 97) and 85% of the maximum (85% of 194 is 164.9). This means that the target heart rate for a 20-year-old is approximately 97–165 bpm. so around 21.

Robert earns $8.65 per hour mowing lawns. A) Write a rule for money m as a function of the number of hours h spent mowing lawns. B) How much does Robert earn if she works 3 hours and 25 minutes?
Answer:
A) [tex]m=8.65h[/tex]
B) $29.58
Step-by-step explanation:
Earnings per hour = $8.65
To find:
A) Write a rule for money m as a function of the number of hours h spent mowing lawns.
Earnings done in one hour = $8.65
Number of hours = [tex]h[/tex]
To find the total earnings, [tex]m[/tex] as a function of number of hours [tex]h[/tex], we need to multiply per hour earnings with number of hours [tex]h[/tex].
Therefore, the equation is:
[tex]m=8.65h[/tex]
B) How much does Robert earn if she works 3 hours and 25 minutes?
First of all, let us convert 3 hours and 25 minutes to hours.
3 hours 25 minutes = 3.42 hours
Therefore, total earnings are:
[tex]m = 8.65\times 3.42 = \$29.58[/tex]

the length of a rectangle is 4 meters less than twice its width. The area of the rectangle is 70. Find the dimensions of the rectangle
Answer: The width is 7 meters. The length is 10 meters.
Step-by-step explanation: Area = Length × width
Length is 2w - 4
Substitute that value for length, then solve for w.
70 = w(2w - 4)
70 = 2w² - 4w reorganize to quadratic equation form
2w² - 4w -70 = 0 These are All even numbers; factor out 2 (divide all by 2)
w² - 2w - 35 = 0 factor this
(w - 7)(w + 5) set each factor = 0 and calculate the value of w.
w+5=0 w= -5 (disregard this one because dimensions of real rectangles can't be negative)
w - 7 = 0 w = 7 The width is 7
Substitute into the original expressions to get the value of Length.
2(7) -4 = L 14 - 4 = L The Length is 10.
Check by substituting into the original equation:
w × 2w -4 = 70
7 × 2(7) -4 = 70
7 × 10 = 70 TRUE!
w
Dimensions of the rectangle are length=10 meter and width= 7 meter
What is Rectangle?A rectangle is a quadrilateral with four right angles.
Given,
The length of a rectangle is 4 meter less than twice its width
Consider,
l is the length of the rectangle
w is the width of the rectangle
l=2w-4
Area of the rectangle = Length × Width
70=l × w
Substitute the value of l is the second equation
70=(2w-4)×w
[tex]2w^{2} -4w=70\\2w^{2} -4w-70=0[/tex]
Take 2 outside
[tex]2(w^{2}-2w-35)=0\\ w^{2} -2w-35=0\\(w+5)(w-7)=0[/tex]
w=7,-5
Hence w wont be negative value
Therefore w=7 meter
Then,
l×w=70
[tex]l=\frac{70}{7}\\[/tex]
l=10 meter
Hence, the dimensions of the rectangle are length=10 meter and width= 7 meter

A) 1.9x10^-2
B) 4.7x10^1
C) 4.7x10^2
D) 1.9x10^-3
ANSWER ASAP PLS
Answer:
Correct Choice: B) 4.7x10^1
Step-by-step explanation:
Scientific Notation
The diameter of a red blood cell is about 0.0008 cm. Expressing in scientific notation, the diameter is [tex]8\cdot 10^{-4} \ cm[/tex].
The diameter of a chickenpox virus is about [tex]1.7\cdot 10^{-5}\ cm[/tex]. It's already expressed in scientific notation.
The ratio of both measures is:
[tex]\displaystyle \frac{8\cdot 10^{-4} \ cm}{1.7\cdot 10^{-5}\ cm}[/tex]
Dividing the coefficients and subtracting the exponents:
[tex]\displaystyle 4.7\cdot 10^{1}[/tex]

Rectangle FGHJ has coordinates F(-8, 6), G(8, 6), H(8,-6), and J(-8, -6). The rectangle is dilated by a scale factor of v with the origin as the center of dilation to form rectangle F'G'H'J'. Which ordered pair represents the coordinates of vertex H'?
Answer:
H'(8v,-6v)
Step-by-step explanation:
Here coordinate of H is (8,-6). We are dilating it using the rule (x,y)-->(kx,ky) where 'k' is scale factor.
For our problem , the dilation factor is "v"
So, image would be (8v,-6v)

At a movie theater, the price of 2 adult tickets and 4 child tickets is $48. The price of 5 adult tickets and 2 child tickets is $64. What is the ticket price for one adult and for one child?
Answer:
10$ for an adult and 7$ for a child
Step-by-step explanation:
price for an adult = a
price for a child = b
2a + 4b = 48.............(i)
5a + 2b = 64.............(ii)
make a subject of the formula in equation (i)
2a = 48 - 4b
divide through by 2
a = 24 - 2b
Insert the value of a in equation (ii)
5(24 - 2b) + 2b = 64
120 - 10b + 2b = 64
collect like terms
- 8b = 64 - 120
-8b = -56
divide both sides by -8
b = 7
insert the value of b in equation(i)
2a + 4(7) = 48
2a + 28 = 48
2a = 48 - 28
2a = 20
divide both sides by 2
a = 10
The price for one adult is $10 while the price for one child is $7
