A towel set consisting of a towel and 6 napkins cost rupees 200 if the cost of each napkin is rupees 95 less than the cost of the towel what is the cost of the towel
Answer:
The towel costs 110 rupees
Step-by-step explanation:
Let n be napkins, and t be towels. Then:
6n+t=200
and
n=t-95
So:
6(t-95)+t=200
7t-570=200
7t=770
t=110....................
Among the set of towels and napkins, the cost of the towel will be equal to 110 rupees.
What is an expression?Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the data given in the question,
Assume that n is for napkins, and t is for towels then,
6n + t = 200 (i)
Also,
The cost of the napkin is rupees 95 less than the towel,
n = t - 95 (ii)
Use equations (i) and (ii)
6(t-95)+t=200
7t-570=200
7t=770
t=110

mike is buying a large pizza the pizza cost $8.00 plus .50 for each addition topping write an equation to show the cost of a large pizza
Answer:
8+(X×0.50)=y
Step-by-step explanation:
We know it costs 0.50 for extra toppings, so X=the amount of toppings and we multiple that by the cost of the toppings. So lets pretend you're getting 3 toppings. 8+(3x0.50)=9.50
Which side lengths form a right triangle?
Choose all answers that apply.
A. square root of 2, square root of 3, square root of 4
B. square root of 8, 3, square root of 17
C. 5, 6, 8
Answer: choice B
Explanation: Go through each answer choice and try the Pythagorean theorem to see if it works. This is because a right triangle’s side lengths are described by the Pythagorean theorem. one side^2 + second side^2 = longest side^2. In a right triangle, this equation will be true. Let me show you what I mean
For answer choice A:
(root 2)^2 + (root 3)^2 = (root 4)^2
2 + 3 = 4
5 = 4
5 does not equal 4. Therefore it cannot be A.
For answer choice B:
(root 8)^2 + (3)^2 = (root 17)^2
8 + 9 = 17
17 = 17
this is true! therefore this is a right triangle and it’s B
Dimensions √17, 3, and √8 are the dimension of the right triangle. Thus, the correct option is B.
What is a Pythagoras theorem?If the dimension satisfies the Pythagorean equation, then the triangle is a right-angle triangle.
The Pythagoras theorem states that the sum of two squares equals the squared of the longest side. The Pythagoras theorem formula is given as,
H² = P² + B²
Let's check the second option, then we have
(√17)² = 3² + (√8)²
17 = 9 + 8
17 = 17
Thus, the correct option is B.

An airplane pilot over the Pacific sights an atoll at an angle of depression of 5 . At this time, the horizontal distance from the airplane to the atoll is 4629 meters. What is the height of the plane to the nearest meter?
Answer:
404.98 m
Step-by-step explanation:
The angle of depression is 5°
The horizontal distance from the airplane to the atoll is 4629 meters.
We need to find the height of the plane.
If we consider a triangle. 4629 meters will be the base and angle is 5°. Let h is the height of the plane. Using trigonometry to find it :
[tex]\tan\theta=\dfrac{x}{4629 }\\\\\tan(5)=\dfrac{x}{4629 }\\\\x=\tan(5)\times 4629 \\\\x=404.98\ m[/tex]
So, the height of the plane is 404.98 m.

How much can the Owen family expect to pay, per year, to raise the child from birth to 18 years of age?
A)$11,378
B)$12,846
C)$13,188
D)$13,458
The Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that,
Cost of raising a child in 2 years
Birth to 5 years old $65,250
5 to 18 years old $139,560
4 y Public college $24,382
4 y private college $98,470
Here, total money = 65,250+139,560+24,382+98,470
= $327662
Money to raise in a year = 327662/18
= $18203
Therefore, the Owen family expect to pay, per year, to raise the child from birth to 18 years of age is $18203.

what is a term called that has no variable? constant or coefficient
Answer: It is constant
Answer:
Constant.
Step-by-step explanation:
Constants are any number that does not have a variable such as x or y, so if they do not have variables, there definitely would not have coefficients. Examples of constants are 2, 5 and 67.
Coefficients are like the 2 in 2x, the 5 in 5y and the 67 in 67xy. All of these numbers have a variable.
Find the perimeter of the triangle.
Answer:
39
Step-by-step explanation:
Alll the sides equal each other because of that curve u see at each angle, that curve means that the angles are the same, having the same angles means same sides, so just pick two equations to do this:
21 - x = 2x -3
add 3 to both sides
24 - x = 2x
add x to both sides
24 = 3x
divide by 3
8 = x
Now input 7 into the equations:
21 - x = 21 - 8 = 13
2(8) - 3 = 16 - 3 = 13
x + 5 = 8 + 5 = 13
Now add: 13 + 13 + 13 = 26 + 13 = 39
Another way for u to save time is remember how i said all the sides were the same? you could just solve one equation, so it'll be 13 and multiply that with 3 to get the perimeter since ur adding 13 three times anyway
So just a simple: 13(3) = 39

In an Animal shelter, the ratio of dogs to cats is 5 to 3. There are 25 dogs, how many cats are there?
Answer: 25:15
Step-by-step explanation: in the ratio 5:3 the 5 is dogs and the 3 is cats you multiply the 5 (aka the dogs) by 5 to get 25 (the amount of dogs in the shelter) when you multiply 3 by 5 you get the amount of cats which is 15, a good way to remember is what you do to one side you have to do to the other.
