Find the perimeter, in inches, of the parallelogram
perimeter of a parallelogram
= 2(l + b)
= 2(8 inches + 6 inches)
= 2(14 inches)
= 28 inches
Step-by-step explanation:
length = 8 inches breadth = 6 inchesperimeter of parallelogram = 2 ( length + breadth )= 2( 8 + 6 )= 2 ×14= 28 inches MARK ME AS BRAINLISTis the ordered pair (1, -3) a solution to
3x + 5y = -8?
Answer:
Yes give Brainliest
Step-by-step explanation:
To find y place the other terms in the equation to the right
hand side of the equation.
Thus : 5y = 7 - 3x
( now divide both sides by 5 )
⇒ 5y5=7−3x5=15(7−3x)

Answer:
a. True
b. True
c. False
d. False
e. Both
Step-by-step explanation:
a. Explanation: each triangle is composed of three interior angles and three sides which can be of the same length or different lengths
b. Explanation: isosceles triangles always have two equivalent interior angles, and all three interior angles of any triangle always have a sum of degrees
c. Explanation: The sum of the measures of the angles is always 180 degrees so that means it is not possible.
d. Explanation: exterior angles of a triangle is greater than either of the measures of the remote interior angles so This is a fundamental result in absolute false because its Interior does not depend upon the Angles
e. Explanation: Eh, There's really no explanation for this So, It's both.

3×1/2 = 1/2 + 1/2 + 1/2 = 3/2 = 1½
A recent General Social Survey asked respondents how many close friends they had. For a sample of 1467 people, the mean was 7.4 and the standard deviation was 11.0. The distribution had a median of 5 and a mode of 4.Based on these statistics, would you expect this distribution to be bell-shaped, left skewed, or right skewed?
Answer:
This distribution should be expected to be right skewed.
Step-by-step explanation:
Pearson skewness:
The skewness of a data set is given by the subtraction of the mean by the mode, divided by the standard deviation.
If the coefficient is positive, the distribution is right skewed.
If the coefficient is negative, the distribution is left skewed.
If the coefficient is sufficiently close to 0(+/- 0.05), the distribution is bell shaped.
In this question:
Mean 7.4, mode 4, standard deviation 11
(7.4-4)/11 = 3.4/11 = 0.31
Positive coefficient, so right skewed.
Lines m and n are parallel Line m is described by the equation y = 40 +2. Line n contains the point (1, -3). Which of the following is an equation for linen?

Answer:
B)Oy+ 3 = 4(x - 1)
Equation of the straight line y +3 = 4( x-1)
Step-by-step explanation:
Explanation:-
Step(i):-
Given that the equation y = 4x +2
and given that the point (1,-3)
The equation of the parallel line to the given line
ax +by +k=0
4x-y +k=0
This line is passing through the point (1,-3)
⇒ 4(1) -(-3) +k=0
⇒ 4+3 +k=0
7 +k=0
k =-7
The equation of the Parallel line 4x-y -7 = 0
Step(ii):-
Given that the slope m = 4 and the point (1,-3)
Equation of the straight line
y - y₁ = m(x-x₁)
y -(-3) = 4( x-1)
y +3 = 4( x-1)

Step-by-step explanation:
Tina found $4.75 at the bottom of her purse and added it to her wallet. She later bought milk and eggs for $6,55 and had
$5.43 left in her wallet
Tina wants to know how much money she had in her wallet before adding the amount she found in her purse (%). Choose ALL
equations in which x correctly represents the amount in her wallet before adding the amount she found,
A)
$6,55 - x + $4.75 - $5.43
B)
x + $4.75 - $6,55 - $5.43
C)
$5.43 -
$6.55 - $1.75 -
Eliminate
D)
$4.75 - $6.55 - $5.43 - X
E)
$5,43 - x + $4.75 - $6.55
Step-by-step explanation:
step 1. x + 4.75 - 6.55 = 5.43
step 2. looks like b is the only answer.

Step-by-step explanation:
Suppose you want to study the relationship between smoking and cancer. You assume that smoking is a cause of cancer. Studies have shown that there are many factors affecting this relationship, such as the number of cigarettes or the amount of tobacco smoked every day; the duration of smoking; the age of the smoker; dietary habits; and the amount of exercise undertaken by the individual. All of these factors may affect the extent to which smoking might cause cancer. These variables may either increase or decrease the magnitude of the relationship. Which statement is false?
a. In the above example cancer is the dependent variable.
b. In the above example cancer is an independent variable.
c. In the above example the extent of smoking is an independent variable.
d. In the above example all the variables that might affect the relationship between smoking and cancer, either positively or negatively, are extraneous or mediating/moderating variables.
Answer:
The correct answer is:
In the above example cancer is an independent variable. (b)
Step-by-step explanation:
In order to explain the choice made, let m first explain what independent and dependent variables are:
Independent variable: An independent variable is a variable that is under the direct control of the experimenter, and can be changed at will. In this example, the number of cigarettes or amount of tobacco smoked is the independent variable because it can be manipulated at will, to determine the outcome of the dependent variable.
Dependent variable: A dependent variable is a variable that the experimenter sets out to study. The independent variable is not under the direct manipulation of the experimenter but has values that come about as a result of the change of the independent variable. In this example, cancer is the dependent variable, because it is the result of the manipulation of the amount of tobacco.
Therefore, it is not true to say that cancer is the independent variable as seen in option b

Q10) A book was sold for Rs. 550 with a profit of 10%. What was its cost price? *
Answer:
CP = Rs 500
Step-by-step explanation:
Given that,
Selling price of a book, SP = Rs 550
Profit percent = 10%
We need to find the cost price of the book. The formula for profit percent is given by :
[tex]P\%=\dfrac{SP-CP}{CP}\times 100\\\\\dfrac{10}{100}=\dfrac{550-CP}{CP}\times 100\\\\\dfrac{1}{10}=\dfrac{550-CP}{CP}\\\\CP=5500-10CP\\\\CP+10CP=5500\\\\11CP=5500\\\\CP=500[/tex]
So, the cost price of the book is Rs 500.
pablo will rent a car for the weekend. he can choose one of two plans. the first plan has an initial fee of $55.96 with additional costs of $0.12 per mile driven. the second plane has an initial fee of $63.96 and costs an additional $0.08 per mile driven. how many miles does pablo drive to make the miles the same?
Answer:
200 miles
Step-by-step explanation:
63.96+(.08x)=55.96+(.12x). x=200. 63.96+(.08x200)=79.96. 55.96+(.12x200)= 79.96

Answer:
[tex]2\sqrt{13}[/tex]
Step-by-step explanation:
Since the 0CA and ACL are equal, we know that OA equals AL.
Using the Pythagorean Theorem, 10^2-6^2=100-36=64.
Under square root 64 is equal to 8, so OL is equal to 8.
Since OA is equal to AL, AL=6.
Again, using the Pythagorean Theorem, 6^2+4^2=36+16=52.
Under square root 52 simplifies to [tex]2\sqrt{13}[/tex]
Hope I helped!
