Se arrastra un bloque de 18 kg a través de una superficie con una fuerza de 300 N en donde el coeficiente de fricción de dicha superficie es de 0.6 . Determine la aceleración resultante en m/s2 que lleva el bloque aproximando el resultado a las décimas.
Answer:
[tex]10.9\ \text{m/s}^2[/tex]
Step-by-step explanation:
m = Masa del bloque = 18 kg
F = Fuerza en el bloque = 300 N
[tex]\mu[/tex] = Coeficiente de fricción = 0.6
El equilibrio de fuerzas del sistema viene dado por
[tex]F-f=ma\\\Rightarrow 300-0.6\times 18\times 9.81=18a\\\Rightarrow a=\dfrac{300-0.6\times 18\times 9.81}{18}\\\Rightarrow a=10.9\ \text{m/s}^2[/tex]
La aceleración del bloque es [tex]10.9\ \text{m/s}^2[/tex].

matthew made slightly larger blanket that was 8 Ft long. Its area is 64 sq ft what is its perimeter?
Answer:
32 ft
Step-by-step explanation:
Given data
Length= 8ft
Area= 64 f^2
Let us find the width
Area= Length*Width
64= 8* Width
Width= 64/8
Width= 8ft
Hence the perimeter= 2L+2W
P= 2*8+2*8
P= 16+16
P= 32 ft
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books. What is the probability one of them is mathematics and other two are either physics or history books
Answer:
Probability that one of them is mathematics and other two are either physics or history books = 0.51
Step-by-step explanation:
Given - A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
To find - What is the probability one of them is mathematics and other two are either physics or history books ?
Solution -
Given that,
A student needs to select 3 books from 3 different mathematics, 3 different physics and 1 history books.
So,
Total number of books = 3 + 3 + 1 = 7
The student has to select 3 books
So, Total number of ways = [tex]^{7} C_{3}[/tex] = 35
So,
Probability that one of them is mathematics and other two are either physics or history books is -
= [tex]\frac{^{3} C_{1}. ^{4} C_{2} }{^{7} C_{3}}[/tex]
= [tex]\frac{(3)(6)}{35}[/tex]
= [tex]\frac{18}{35}[/tex]
= 0.51
⇒Probability that one of them is mathematics and other two are either physics or history books = 0.51

A national health organization warns that alcohol use among middle school students is on the rise. Concerned, a local health agency randomly and anonymously surveys 110 of the middle school students in its city. 21 of them report having been intoxicated. Create a 90% confidence interval. Find p-hat. (p -hat = x/n)
Answer:
CI 90 % = [ 0,05 ; 0,16 ]
Step-by-step explanation:
From sample we got
n = 110
x = 21
p = 21/110 = 0.19 then q = 1 - p q = 1 - 0.19 q = 0.81
To create a 90 % confidence Interval, the significance level α = 10 %
α = 0.1 α/2 = 0.05
t(c) for α/2 = 0.05 is from z-table z(c) = 1.64
CI 90 % = ( p ± z(c) * √(p*q)/n
CI 90 % = [ 0,11 ± 1.64 * √ (0.19*0.81)/110 ]
CI 90 % = [ 0.11 ± 1.64 * 0.037 ]
CI 90 % = [ 0.11 ± 0,06 ]
CI 90 % = [ 0,05 ; 0,16 ]

Ali and mo share a sum of money in the ratio ali : mo = 9 : 7 ali receives 600 more than mo calculate how much each receives
Step-by-step explanation:
Given :-
Ali and mo share a sum of money in the ratio ali : mo = 9 : 7 .Ali receives 600 more than mo .And we need to find out how much each receives .Let us take that
Mo received x .Ali will get x + 600.According to the Question :-
[tex]\implies \dfrac{9}{7}=\dfrac{x+600}{x}\\\\\implies 9x = 7x + 4200 \\\\\implies 2x = 4200 \\\\\implies x = 2100 [/tex]
Therefore :-
Ali = x+600 = 2700Mo = x = 2100Answer:
ali:mo=937.5 and 262.5

A circle with a center at (2,-3) passes through the point (-1,-8). Write the equation of the circle.
Answer: (x - 2)^2 + (y + 3)^2 = 34
Step-by-step explanation:
The basic equation for a circle is
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the centre of the circle
Using Pythagoras we can find r^2
r^2 = (2 - -1)^2 + (-3 - -8)^2
= 3^2 + 5^2
= 34
So the circle is (x - 2)^2 + (y - -3)^2 = 34
The Equation of Circle is (x -2)² + ( y + 3)² = 34.
What is Equation of Circle?The standard equation of a circle is given by: (x-h)² + (y-k)² = r². Where (h,k) is the coordinates of center of the circle and r is the radius.
We know the standard form of Equation of Circle
(x - a)² + (y - b)² = r²
where (a, b) is the Centre of the circle
Also, we have a circle with a center at (2,-3) passes through the point (-1,-8).
Using Pythagoras theorem
r² = (2 - -1)² + (-3 - -8)²
= 3² + 5²
= 34
Thus, the Equation of Circle is (x -2)² + ( y + 3)² = 34.

Carmen wants to join a gym. Gym A costs $26.76 plus an additional $4 for each visit. Gym B has no initial fee but costs $12.92 for each visit. After how many visits will both plans cost the same?
Answer:
After 3 visits both plans will cost the same.
Step-by-step explanation:
Gym A costs $26.76 plus an additional $4 for each visit.
Gym B has no initial fee but costs $12.92 for each visist.
The cost for gym A can be written as
C= $26.76 + 4(x) where x is the number of visits to the gym A
The cost for gym B can be written as
C= $12.92 (x) where x is the number of visits to the gym B
Both costs will be equal
12.92x= 26.76 +4x
12.92x-4x= 26.76
8.92x= 26.76
x= 26.76/8.92
x= 3
after 3 visits both plans will cost the same.
Check
12.92x= 26.76 +4x
12.92*3= 26.76 +12

Quadrilateral WXYZ has vertices at the points W(-3,2), X(-1,3), Y(0,1), and Z(1,0). Find the slope of side xy.
Answer:
The slope of the side xy is -2
Step-by-step explanation:
To find the slope of the side xy, we use the slope formula
we have the formula as;
m = (y2-y1)/(x2-x1)
(x1,y1) = (-1,3)
(x2,y2) = (0,1)
m = (1-3)/(0 + 1) = -2/1 = -2

Find the measure of x and y.
Answer:
x = 24°, y = 53°
Step-by-step explanation:
An inscribed angle is half the measure of its intercepted arc.
arc EC = 2 × ∠ EDC = 2 × 78° = 156°
x = arc BE = 180° - arc EC = 180° - 156° = 24°
------------------------------------------------------------------
arc CD = 2 × CED = 2 × 41° = 82°
arc BD = 180° - arc CD = 180° - 82° = 98° , then
∠ BCD = [tex]\frac{1}{2}[/tex] × 98° = 49°
Then
y + 78° + 49° = 180° (sum of angles in triangle )
y + 127° = 180° ( subtract 127° from both sides )
y = 53°

Laurie is trying to stay within 10 feet of her current diving depth of -30 feet (with regard to sea level) so that the light
is still good but she can be close to the sea life during her scuba dive. Which two equations can be used to find the
minimum and maximum depths Laurie wants to stay between?
-30 - x = 10 and -30 - x = -10
• -30 + x = 10 and -30 + x = -10
O x + 10 = 30 and x + 10 = -30
O x - 10 = 30 and x - 10 = -3
Answer:
[tex] \boxed{-30\:– \: x \:= \: 10 \: \: and \: -30 - x = -10} [/tex]
The equations can be used to find the minimum and maximum depths are (a) [tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]
The current diving depth (d) is given as:
[tex]d = -30ft[/tex]
The position (p) she tries to stay is given as:
[tex]p = 10ft[/tex]
Represent the minimum and the maximum distances with x.
So, the distances are calculated using:
[tex]d - x = p[/tex] and [tex]d - x = -p[/tex]
Substitute values for d and p
[tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]
Hence, the equations can be used to find the minimum and maximum depths are (a) [tex]-30 - x = 10[/tex] and [tex]-30 - x = -10[/tex]

A conservationist is tracking the number of a rare type of tree in a forest as it recovers from a fire.
During the first 4 years after the fire, she records 2, 6, 18, and 54 trees. If this trend continues, which
expression can be used to find the number of trees after n years?
Answer:
The expression is [tex]T(n) = 2*(3)^n[/tex]
Step-by-step explanation:
Geometric sequence:
In a geometric sequence, the quotient between consecutive terms is always the same.
The general rule of an geometric sequence is given by:
[tex]T(n) = T(0)(q)^n[/tex]
In which T(0) is the initial amount and q is the quotient.
During the first 4 years after the fire, she records 2, 6, 18, and 54 trees.
First term is 2, so [tex]T(0) = 2[/tex].
Quotient is [tex]q = \frac{54}{18} = \frac{18}{6} = \frac{6}{2} = 3[/tex]
So
[tex]T(n) = T(0)(q)^n[/tex]
[tex]T(n) = 2*(3)^n[/tex]
The expression is [tex]T(n) = 2*(3)^n[/tex]
