A rectangles width is 13 more than its length. If the perimeter is 82 feet what is the length and width.
Answer:
Step-by-step explanation:
Lenght should be the greater here. I am considering your question however.
Let length side is 'x'.
The width side is 'x +13'
Perimeter of a rectangle : 2 ×( length + width)
given that perimeter is 82
2 × ( x + x + 13) = 82
2 × ( 2x + 13) =82
4x + 26 = 82
2x = 56
x = 28 cm
length is 28
width is 41
(2x + 5)(2x + 1)

Answer:
I had no idea what u were asking but i solved for r and got r>45
Answer:
r > 45
Step-by-step explanation:
6 <-3 + r/5
add 3 left and right of the < sign gives:
6 +3 <-3 +3 + r/5
9 < 0 + r/5
9 < r/5
multiply left and right of the < sign gives by 5 gives:
9 * 5 < 5* r/5
45 < r
r > 45

pls help asap thanks .
Answer:
n/a
Step-by-step explanation:
A. t(h) = 5.5h + 50
B. t(6) = 5.5(6) + 50
t(6) = 85
C. (6, 85) This means that when the electrician for 7 hours, they get paid $85
Answer:
A) 50+5.50h=t
B) 50+5.50(6)=83
C)6,83
Step-by-step explanation:
A) 50+5.50h=t
B) 50+5.50(6)=83
50+33=t
83=t
C) (6,83)
If h is 6, plus the first hour of 50 dollars, 83 dollars is the amount of pay you would receive

Which relationships have the same constant of proportionality between yyy and xxx as the equation y=\dfrac{1}{2}xy= 2 1 xy, equals, start fraction, 1, divided by, 2, end fraction, x? Choose 3 answers: Choose 3 answers:
Answer:
A & B
Step-by-step explanation:
See attachment for complete question
Given
[tex]y = \frac{1}{2}x[/tex]
Analyzing the given options
Option A:
[tex]6y = 3x[/tex]
Divide both sides by 6
[tex]\frac{6y}{6} = \frac{3x}{6}[/tex]
[tex]y = \frac{3x}{6}[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is true for the given expression:
Option B:
From the graph:
x = 2, when y = 1
x = 4, when y = 2
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2 -1}{4 - 2}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{2}(x - 2)[/tex]
[tex]y - 1 = \frac{1}{2}x - 1[/tex]
Add 1 to both sides
[tex]y - 1 +1 = \frac{1}{2}x - 1 + 1[/tex]
[tex]y = \frac{1}{2}x[/tex]
This is also true for the given expression.
Option C:
From the graph:
x = 2, when y = 4
x = 4, when y = 8
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{8 - 4}{4 - 2}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m =2[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 4 = 2(x - 2)[/tex]
[tex]y - 4 = 2x - 4[/tex]
Add 4 to both sides
[tex]y - 4 + 4= 2x - 4 + 4[/tex]
[tex]y = 2x[/tex]
This isn't true for the given expression.
Option (D):
From the table:
x = 2, when y = 1
x = 4 when y = 3
Solving for the slope:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{3 - 1}{4 - 2}[/tex]
[tex]m = \frac{2}{2}[/tex]
[tex]m = 1[/tex]
The equation is then calculated as:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = 1 * (x - 2)[/tex]
[tex]y - 1 = x - 2[/tex]
[tex]y = x - 2 +1[/tex]
[tex]y = x - 1[/tex]
This isn't true for the given expression.

Answer:
DONDODA
Step-by-step explanation:
Complete the process of solving the equation. Fill in all missing terms and select all missing descriptions. Simplify any fractions. 11a+2=9a+4 2a+2=4 Add 9a to both sides Subtract 9a from both sides Multiply both sides by 9a Divide both sides by 9a Apply the distributive property 2a= Subtract 2 from both sides a= Divide both sides by 2
Answer:
11a + 2 = 9a + 4 ( Subtract 9a from both sides)
11a - 9a + 2 = 9a - 9a + 4
2a + 2 = 4 (Subtract 2 from both sides)
2a + 2 - 2 = 4 - 2
2a = 2 (Divide both sides by 2)
2a/2 = 2/2
a = 1
Step-by-step explanation:
Simplify any fractions.
11a + 2 = 9a + 4
2a + 2= 4
We simplify as shown below
11a + 2 = 9a + 4 ( Subtract 9a from both sides)
11a - 9a + 2 = 9a - 9a + 4
2a + 2 = 4 (Subtract 2 from both sides)
2a + 2 - 2 = 4 - 2
2a = 2 (Divide both sides by 2)
2a/2 = 2/2
a = 1
Find the inverse of Function F.
F(x)=9x+7
Answer:

Mathematics, 04.12.2019 23:31, datboyjulio21
For 1992 through 1994, the per capita consumption of fish and shellfish in the
u. s. increased at a rate that was approximately linear. in 1992, the per capita
consumption was 14.7 pounds, and in 1994 it was 15.1 pounds."
36. write a linear model for the per capita consumption of fish and shellfish
in the u. s. let t represent the number of years since 1992.
37. what would you expect the per capita consumption of fish and shellfish
to be in 2002?
Answer:
The answer is below
Step-by-step explanation:
A linear equation is represented by the equation y = mx + b, where m is the rate of change, b is the value of y at x = 0, y is a dependent variable and x is an independent variable.
Let t represent the number of years since 1992, and P represent the per capita consumption of fish and shellfish in the U.S.
In 1992 (t = 0), the per capita consumption was 14.7 pounds, this can be represented by (0, 14.7) while in 1994 (t = 1994-1992=2) it was 15.1 pounds this can be represented by (2, 15.1)
Using (0, 14.7) and (2, 15.1) we can get the equation of the line using:
[tex]P-P_1=\frac{P_2-P_1}{t_2-t_1}(t-t_1)\\ \\P-14.7=\frac{15.1-14-7}{2-0}(t-0)\\ \\P-14.7=0.2t\\\\P=0.2t+14.7[/tex]
In the year 2002 (t = 2002-1992 = 10), the per capita consumption of fish and shellfish is:
P = 0.2(10) + 14.7
P = 16.7 pounds
Felipe and Makayla each tried to solve the same
equation for x.
Original equation: 2x + 6 = 3x - 8
The result of Felipe's first step was -x + 6 = 8.
Describe the first step Felipe made to the equation
Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8
What is a function?
An expression in mathematics defines a relationship between one variable (the independent variable, x) and another variable (the dependent variable, y). For example -
f(x) = 4x + 6
Given is the equation equating two functions as -
2x + 6 = 3x - 8
We have -
2x + 6 = 3x - 8
2x - 3x + 6 = 8
-x + 6 = 8
Therefore, Felipe in the first step shifted 3x from R.H.S. to L.H.S. as -
2x - 3x + 6 = 8

Step-by-step explanation:
Gabriela Mistral was a poet, diplomat, teacher and humanitarian. Each week she worked a certain amount of days as a poet diplomat teacher and humanitarian. This ratio was one day as a poet to one day as a diplomat to three days as a teacher to two days as a humanitarian how many days must she work as a humanitarian if she works 12 days as a teacher?
Answer:
Gabriela Mistral works as a humanitarian for [tex]8[/tex] days.
Step-by-step explanation:
Gabriela Mistral was a poet, diplomat, teacher and humanitarian such that each week she worked a certain amount of days as a poet diplomat teacher and humanitarian.
Ratio is [tex]1:1:3:2[/tex]
Let [tex]x[/tex] denotes total number of days Gabriela Mistral work.
As she works 12 days as a teacher,
[tex]\frac{3}{7}x=12\\ x=\frac{7}{3}(12)\\ x=28[/tex]
Total number of days [tex]=x=28[/tex]
So,
she works as a humanitarian for [tex]\frac{2}{7}x=\frac{2}{7}(28)=8[/tex] days.

convert .932 into a fraction
Answer:
932/1000
Step-by-step explanation:
To write .932 as a fraction you have to write .932 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
.932 = .932/1 = 9.32/10 = 93.2/100 = 932/1000
And finally we have:
.932 as a fraction equals 932/1000
Answer:
923/1000
