a fair 6 sided dice is rolled twice, what is the probability it will land on a 1 both times?
Answer:
The answer is 1/36
Step-by-step explanation:
The probability that it will land on 1 at any time is 1/6
So for the first time we have 1/6
For the second time, we have 1/6
For the both times, we have
1/6 * 1/6 = 1/36

Find the measures of the interior angles of the triangle.
The triangle shown is an equilateral triangle. An equilateral triangle has sides lengths a. What is the area of the equilateral triangle with the length of each side equal to a? One-half a sine (60 degrees) 3 a sine (60 degrees) One-half a squared sine (60 degrees) a squared sine (60 degrees)
Answer: its C
Step-by-step explanation:
The area of an equilateral triangle can be written as a squared sine (60 degrees) thus Option D is correct.
What is an equilateral triangle?The triangle in which all three sides are of the same length. In this the all angles are the same 60°.
The area of a triangle can be calculated by,
A = 1/2 x b x h..................1
Where,A - Area of triangle
b - base
h - height
From, Pythagoras Theorem
a² = h² + (a/2)²
h² = a² - (a/2)²
Put the value of “h” in equation 1
A = 1/2 x b x h
A = 1/2 x √[a² - (a/2)²] x h
A = √3/4 a²
Since √3/4 = sin 60°.
So, the area of an equilateral triangle as a squared sine (60 degrees).

Susan purchased a prepaid phone card for $15. Long distance calls cost 14 cents a minute using this card. Susan used her card only once to make a long distance call. If the remaining credit on her card is $9.26, how many minutes did her call last?
Answer:
41 minutes
Step-by-step explanation:
Step one:
given data
Susan purchased a prepaid phone card for $15
let the number of minutes be x
and let the total be y
per minute call cost = 14 cents = $0.14 per minute
Hence the expression for the situation is given as
y= 15-0.14x
Step two:
given that the balance after a call is 9.26
9.26=15-0.14x
solve for x
9.26-15= -0.14x
5.74=0.14x
divide both sides by 0.14
x=5.74/0.14
x=41 minutes

De un bote con 180 caramelos Laura se ha comido una decima parte, Marta una novena parte y Cristina una quinta parte. De lo que queda, Juan se ha comido la mitad. ¿ Cuantos caramelos quedan?
Answer:
53 caramelos
Step-by-step explanation:
El número total de caramelos en el frasco = 180 caramelos
Para Laura
Laura se ha comido la décima parte de un frasco
1/10 × 180 caramelos = 18 caramelos
Por Marta
Marta una novena
1/9 × 180 = 20 caramelos
Por Cristina
Cristina una quinta.
1/5 × 180 = 36 caramelos.
De lo que queda, Juan se ha comido la mitad.
La cantidad de caramelos que quedan se calcula como:
180 - (18 + 20 + 36)
= 180 - 74
La cantidad de caramelos que quedan = 106 caramelos
Para juan
De lo que queda, Juan se ha comido la mitad.
= 1/2 × 106
= 53 caramelos
¿Cuántos dulces quedan?
= 106 caramelos - 53 caramelos
= 53 caramelos
Por tanto, quedan 53 caramelos.
The width of a rectangle is 30 less than 4 times the length. The perimeter is 60. What is the length, width, and area
9514 1404 393
Answer:
length: 12 unitswidth: 18 unitsarea: 216 square unitsStep-by-step explanation:
Let x represent the length of the rectangle. Then the width is 4x-30, and the perimeter is ...
P = 2(L +W)
60 = 2(x +(4x -30)
30 = 5x -30
60 = 5x
12 = x . . . . length
4x -30 = 18 . . . . width
Area is the product of length and width.
A = LW
A = (12)(18) = 216
The length is 12, the width is 18, and the area is 216.

find the holes
[tex]f(x)=\frac{x+3}{(x+1)(x-2)}[/tex]
Answer:
x=-1 and x=2Step-by-step explanation:
The "holes" are the x-es where function doesn't exist.
one must not divide by 0, so given function doesn't exis if the denominator is equal 0
The product {(x+1)×(x-2)} is equal 0 if any of factors {(x+1),(x-2)} is 0, so
x + 1 = 0 or x - 2 = 0
x = - 1 or x = 2
Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks. Craig's Bakery recently spent a total of $311 on new equipment, and their average hourly operating costs are $9. Their average hourly receipts are $10. The bakery will soon make back the amount it invested in equipment. How many hours will that take? What would the total expenses and receipts both equal?
Answer:
a. 311 hours
b. i. $3,100 in receipts
ii. $2,799 in expenses.
Step-by-step explanation:
a. The company is making $10 per hour and spending $9 an hour. Their profit is therefore:
= 10 - 9
= $1 per hour
Since they spent $311 on the new equipment, the amount of time it would take for them to make this back is:
= 311 / 1
= 311 hours
b. In 311 hours, the total receipts would be:
= 311 * 10
= $3,110
The expenses would be:
= 311 * 9
= $2,799

Does this graph show a function? why or why not?
It is a function because we do not have two or more red points vertically aligned. In other words, we don't have any red points stacked. This graph passes the vertical line test.
The vertical line test is where we try to find a single vertical line passing through more than one red point. No such vertical line exists, so that's why this graph passes. Passing the vertical line test means we therefore have a function.
A function is where any input x leads to exactly one output. For instance, the input x = 9 leads to the single output y = 28. Similar situations happen with the other x values as well. If we had the two points (9,28) and (9,36), then this wouldn't be a function.

Answer:
1. 4
2. 16
3. 8
Step-by-step explanation:
1. 4^2 / 2^2
4^2 = 16
2^2 = 4
16/4 = 4
2. (8- 4) x 4
8 - 4 = 4
4 x 4 = 16
3. 2^2 + 2^2
2^2 = 4
2^2 = 4
4 + 4 = 8
Hope I helped!
Answer:
[tex]\frac{4^{2} }{2^{2} } = 4[/tex]
(8 - 4) x 4 = [tex]4^{2}[/tex]
[tex]2^{2} +2^{2}[/tex] = 8
Step-by-step explanation:
[tex]\frac{4^{2} }{2^{2} } = 4[/tex] because [tex]4^{2} = 16[/tex] and [tex]2^{2}[/tex] = 4. 16/4 is the same as 4.
(8 - 4) x 4 = (4) x 4 = 16. This is the same as [tex]4^{2}[/tex].
[tex]2^{2} +2^{2}[/tex] is the same as 4 + 4, which is 8.
Hope it helps!
