El piso de un habitación es de forma cuadrada. Tiene 10m de longitud por lado y debe ser cubierto con losetas cuadradas de 25cm de lado. ¿Cuantas losetas serán necesarias?
Answer:
4 fichas
Step-by-step explanation:
Paso 1
Encontramos el área de la habitación cuadrada.
Área de un cuadrado = longitud del lado²
Longitud lateral = 10 cm
Área del piso cuadrado = (10cm) ²
= 100 cm²
Paso 2
El suelo debe estar cubierto con baldosas cuadradas de 25 cm.
Por lo tanto: El número de mosaicos que serán necesarios =
Área del piso cuadrado ÷ Área de las baldosas
= 100cm² / 25 cuadrados
= 4 fichas
Determine the smallest integer value of x in the solution of the following inequality.
4x – 1 > 18
Answer:
x = 5
Step-by-step explanation:
You need to find de value of x.
4x - 1 = 18
4x = 18 + 1
4x = 19
x = 19/4
x = 4,75 but, the questions says: smallest integer value, so, the smallest is the integer number more near of 4,75, which is 5.
testing:
x = 5
4*5 - 1 > 18
20 -1 > 18
19 > 18 TRUE
x = 4
4*4 - 1 > 18
16 - 1 > 18
15 > 18 FALSE

A store is having a sale on jellybeans in trail mix. For 2 pounds of jellybeans and 12 pounds of trail mix, the total cost is $23. For 5 pounds of jellybeans and 3 pounds of trail mix, the total cost $17 find the cost for each pound of jellybeans in each pound of trail mix
Answer:
The jelly beans cost $2.25 / pound
The trail mix costs $1.25 / pound
Step-by-step explanation:
Let +a+ = cost/pound of jelly beans
Let +b+ = cost/pound of trail mix
(1) 6a + 2b =16
(2) 3a + 5b =13
Multiply both sides by 2
and subtract (1) from (2)
(2) 6a -2b = -16
(1) -6a -2b = -16
8b=10
b=1.25
and
(1) 6a+2b=16
(1) +3a+b=8
(1) 3a+1.25=8
(1) +3a=6.75
(1) a=2.25

If m angle RTS = 8x + 18, find x so that line TR is perpendicular to line TS
Answer:
Point T is the right angle of the triangle, so RTS = 90 degrees
8x + 18 = 90 (degrees)
8x = 72
x = 9 degrees
Step-by-step explanation:
If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].
What is perpendicular ?A line is said to be perpendicular to another line if the two lines intersect at a right angle i.e. make [tex]90^0[/tex] angle with that line.
We have,
[tex]\triangle RTS[/tex] in which,
[tex]\angle RTS=8x+18[/tex]
Also it is mentioned that [tex]TR \perp TS[/tex] i.e.
[tex]\angle RTS=90^0[/tex]
So, compare values of [tex]\angle RTS[/tex],
We get,
[tex]8x+18=90[/tex]
[tex]8x=72[/tex]
[tex]x=9^0[/tex]
Hence, we can say that If [tex]\angle RTS = 8x + 18[/tex] and line [tex]TR[/tex] is perpendicular to line [tex]TS[/tex], then [tex]x[/tex] will be [tex]9^0[/tex].

if csc θ = -5/4 on the interval (270°, 360°), find tan θ.
Value of tan θ on the interval (270°, 360°) = -4/3
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, square of length of hypotenuse is equal to the sum of squares of lengths of other two sides, i.e. Perpendicular and base.
Given,
cosec θ = -5/4 on the interval (270°, 360°)
Given interval is on fourth quadrant.
Sine and cosecant are negative in fourth quadrant
cosec θ = -5/4
cosec θ = Hypotenuse/perpendicular
Comparing
Hypotenuse = 5
Perpendicular = 4
By Pythagoras theorem,
Base² = Hypotenuse² - Perpendicular²
Base² = (5)² - (4)²
Base² = 25 - 16
Base² = 9
Base = ±3
In fourth quadrant tangent is negative
tan θ = -4/3
Hence, -4/3 is the value of tan θ on the interval (270°, 360°).

Find the 25th term of the sequence -7,-22,-37.
Answer:
a₂₅ = - 367
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 22 - (- 7) = - 37 - (- 22) = - 15
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 15 , then
a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367

Find the PERIMETER and the AREA of the following figure,
16 ft
8 ft
10 ft
9514 1404 393
Answer:
perimeter: 36 +16√5 ft ≈ 71.777 ftarea: 288 ft²Step-by-step explanation:
Perimeter
The perimeter is the total length of all the sides. The length of the horizontal sides is 8 ft + 10 ft = 18 ft. The length of the slant sides can be found using the Pythagorean theorem. For side length s, we have ...
s^2 = 8^2 + 16^2
s^2 = 64 +256 = 320
s = √320 = 8√5
Then the perimeter is ...
P = 2(8√5 + 18) = 36 +16√5 ≈ 71.777 . . . feet
__
Area
The area is given by the formula ...
A = bh
where b is the base and h is the height.
A = (18 ft)(16 ft) = 288 ft²
