find the perimeter of rectangle.
Answer:
it depends on how big the rectangle is though...
Step-by-step explanation:
Answer:
6x + 10
Step-by-step explanation:
Given,
Length ( l ) = 3x
Breadth ( b ) = 5
To find : Perimeter of the rectangle = ?
Formula : -
Perimeter of the rectangle = 2 ( l + b )
Perimeter of the rectangle
= 2 ( 3x + 5 )
= 2 ( 3x ) + 2 ( 5 )
= 6x + 10

Samantha spent 40 minutes on homework sixty percent of that time was spent on language arts how many minutes were spent in language art
Answer:
i think its b.24 minutes
Step-by-step explanation:
sorry if im wrong
Answer:
Samantha spent 24 minutes on language arts.
Step-by-step explanation:
So, 60% = 3/5.
Since Samantha spent 40 minutes in total for homework, the 40 minutes would be the denominator. Let's have the variable "x" equal how many minutes she spent on language arts. If we line up the fractions, it will be like this:
3/5 = x/40
Since we know 5 x 8 = 40, we would also multiply the numerator by 8.
3 x 8 =24.
So, Samantha spent 24/40 minutes on ELA, which is 60% of the total time.

find csc θ and sec θ if cot θ= 3/2 and cos θ>0
Since both cot(θ) and cos(θ) are positive, it follows that sin(θ) is also positive:
cot(θ) = cos(θ)/sin(θ) > 0 ===> sin(θ) > 0
Recall the Pythagorean identity:
sin²(θ) + cos²(θ) = 1
Multiplying both sides by 1/sin²(θ) yields another form of the identity,
sin²(θ)/sin²(θ) + cos²(θ)/sin²(θ) = 1/sin²(θ)
1 + cot²(θ) = csc²(θ)
so that
csc(θ) = + √(1 + cot²(θ))
csc(θ) = √(1 + (3/2)²)
csc(θ) = √13/2
By definition of cosecant, we have
csc(θ) = 1/sin(θ)
so that
sin(θ) = 2/√13
Then using the Pythagorean identity once more, we have
cos(θ) = + √(1 - sin²(θ))
cos(θ) = √(1 - (2/√13)²)
cos(θ) = 3/√13
so that, by definition of secant,
sec(θ) = 1/cos(θ)
sec(θ) = √13/3

Option C
From the question we are told
What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?
A) 78
B) 32
C) 14
(Explain your work)
Generally the equation for the arithmetic sequence is mathematically given as
[tex]a_4=a_1+(n-1)d[/tex]
Therefore
For seventh term
[tex]5=23+(6)d\\\\d=5-23/(6)\\\\d=-3[/tex]

Answer:
[tex]p=36^{\circ}[/tex]
Step-by-step explanation:
We can prove that a tangent will always be perpendicular to the radius touching it. So, the other angle in the diagram is [tex]90^{\circ}[/tex].
Because all the angles of a triangle sum to [tex]180^{\circ}[/tex], we have that [tex]p+54+90=180[/tex].
We combine like terms on the left side to get [tex]p+144=180[/tex].
We subtract [tex]144[/tex] on both sides to get [tex]p=36[/tex].
So, [tex]\boxed{p=36^{\circ}}[/tex] and we're done!

The arithmetic mean of ten numbers is -10. If the sum of six of the numbers is 100, what is the arithmetic mean of the other 4?
Answer:
56
Step-by-step explanation:
Arithmetic mean is simply the sum of the all the number present divide by the total number.
From the question, we obtained the following information:
The arithmetic mean = 5.6
Total number present = 10
Sum of the numbers =?
Arithmetic mean = sum of the numbers / total number
Sum of the numbers = arithmetic mean x total number
Sum of the numbers = 5.6 x 10 = 56
The sum of the other four numbers is equivalent to -200.
What is a mathematical function, equation and expression? function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is that the arithmetic mean of ten numbers is -10. The sum of six of the numbers is 100.
We can write -
{a + b + c + d + e + f + g + h + i + j}/10= - 10
{a + b + c + d + e + f + g + h + i + j} = - 10 x 10
{a + b + c + d + e + f + g + h + i + j} = - 100 .... Eq{1}
and
{a + b + c + d + e + f} = 100 .... Eq{2}
We can write Eq{1} as -
{a + b + c + d + e + f} + {g + h + i + j} = - 100
100 + {g + h + i + j} = - 100
{g + h + i + j} = - 100 - 100
{g + h + i + j} = - 200
Therefore, the sum of the other four numbers is equivalent to -200.

I have written the answers and the steps on a piece of paper.
detailed explanation and answer please 20 points
Step-by-step explanation:
The first part of solving the area is multiplying the rectangle. So you do 15*18 which is 270. Then to solve a triangle you make it a square/rectangle. So it would be 8*15 which is 120. Because the length is the length of the rectangle and the width is shown on top. Then because it’s a rectangle not a triangle you divide by 2 because you were adding half to it when you were making it a rectangle. So it’s 120/2 which is 60. And 270+60 is 330. So the area is 330. To get the perimeter you add all the sides together. And because one of the sides is not added but half of the bottom line is the same length as the top so it would be 18+ the 8 on the top which is 26. So 15+18+17+26 is 76. So the perimeter is 76
So the answer is the bottom one. P=76 and A=330

Step-by-step explanation:
Evaluate.
(jk−1) ÷j when j=−4 and k=−0.8
Enter your answer as a decimal in the box.
Step-by-step explanation:
(jk−1) ÷j
[(-4)(-0.8) -1] ÷ (-4)
=[ 3.2 -1] ÷ (-4)
=2.2 ÷ (-4)
= -0.55
The solution of the expression "[tex]\frac{jk-1}{j}[/tex]" is "-0.55".
The given values are:
j = -4k = -0.8→ [tex]\frac{jk-1}{j}[/tex]
By putting the value of "j" and "k" in the given expression, we get
→ [tex]\frac{(-4)(-0.8)-1}{-4}[/tex]
By solving the brackets, we get
→ [tex]\frac{3.2-1}{-4}[/tex]
→ [tex]\frac{2.2}{-4}[/tex]
→ [tex]-0.55[/tex]
Thus the above response is correct.
