Answer:
x=10
Step-by-step explanation:
-18x + 30 = -150
subtract 30 from both sides = -18x=-180
divide both sides by -18 = x=10
x=10
¿Cuántos enteros divisibles por 4 y por 9 hay entre 95 y 450?
Answer:
Hay 10 enteros divisibles por 4 y por 9 entre 95 y 450.
Step-by-step explanation:
Podemos reescribir esta pregunta como sigue: ¿Cuántos números entre 95 y 450 son divisibles por 36? Entonces, existe un conjunto de números enteros [tex]A[/tex] tal que cada elemento satisface la condición que:
[tex]A = \{x= \frac{n}{36}\,\land \,95\le n \le 450, n, x\in \mathbb{Z}\}[/tex] (1)
Sabemos que el entero más pequeño divisible por 36 es:
[tex]x_{min} = \frac{108}{36}[/tex]
[tex]x_{min} = 3[/tex]
Mientras que el entero más grande divisible por 36 es:
[tex]x_{max} = \frac{432}{36}[/tex]
[tex]x_{max} = 12[/tex]
La cantidad de enteros divisibles se obtiene a través de la siguiente expresión algebraica:
[tex]a = 1+(x_{max}-x_{min})[/tex] (2)
[tex]a = 1+(12-3)[/tex]
[tex]a = 10[/tex]
Hay 10 enteros divisibles por 4 y por 9 entre 95 y 450.

Answer:
[tex]\sqrt3[/tex]
Step-by-step explanation:
To find:
The value of [tex]tan60^\circ[/tex] = ?
Solution:
Kindly consider the equilateral [tex]\triangle ABC[/tex] as attached in the answer area.
Let the side of triangle = [tex]a[/tex] units
Let us draw the perpendicular from vertex A to side BC.
It will divide the side BC in two equal parts.
i.e. BD = DC = [tex]\frac{a}{2}[/tex]
Using Pythagorean Theorem in [tex]\triangle ABD[/tex]:
[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}[/tex]
Side AD = [tex]\frac{\sqrt3}{2}a[/tex]
Using Trigonometric ratio:
[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]
[tex]tanB = \dfrac{AD}{BD}[/tex]
Putting the values of AD and BD:
[tex]tan60^\circ=\dfrac{\frac{\sqrt3}{2}a}{\frac{1}{2}a}\\\Rightarrow tan60^\circ = \bold{\sqrt3}[/tex]

A factory makes Jars in batches of 160 and lids in batches of 216. The next puts the jars in a row, fills them and then attaches the lid. They want to make the largest row possible so the jars and lids are divided evenly by the rows. What is the largest row possible?
Answer:
8 is the largest row possible
Step-by-step explanation:
What this question is simply asking is to find the greatest common factor of 216 and 160
The greatest common factor of 216 and 160 is 8
So what this mean is that the largest row possible is 8
Triangle LMN with vertices L(0, 3), M(3, 4), and N(1, 2): a) 180° rotation about the origin b) dilation with scale factor of 2 using the origin as the center
Answer:
[tex]L" = (-6,0)[/tex] [tex]M" = (-8,-6)[/tex] [tex]N" = (-4,-2)[/tex]
Step-by-step explanation:
Given
[tex]L = (0,3)[/tex]
[tex]M = (3,4)[/tex]
[tex]N = (1,2)[/tex]
Required
Determine the new coordinates of L, M and N
Applying (a): 180 degrees rotation about the origin
When [tex](x,y)[/tex] is rotated about 180 degrees, the new point becomes [tex](-y,-x)[/tex]
So:
[tex]L = (0,3)[/tex] ==> [tex]L' = (-3,0)[/tex]
[tex]M = (3,4)[/tex] ==> [tex]M' = (-4,-3)[/tex]
[tex]N = (1,2)[/tex] ==> [tex]N' = (-2,-1)[/tex]
Applying (b): Dilation of scale factor, 2
The formula to apply here is;
[tex]New = Old * Scale\ Factor[/tex]
So:
[tex]L' = (-3,0)[/tex] becomes:
[tex]L" = L' * 2[/tex]
[tex]L" = (-3,0) * 2[/tex]
[tex]L" = (-6,0)[/tex]
[tex]M' = (-4,-3)[/tex] becomes:
[tex]M" = M' * 2[/tex]
[tex]M" = (-4,-3) * 2[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N' = (-2,-1)[/tex]
[tex]N" = N' * 2[/tex]
[tex]N" = (-2,-1) * 2[/tex]
[tex]N" = (-4,-2)[/tex]
Hence;
The new coordinates are:
[tex]L" = (-6,0)[/tex]
[tex]M" = (-8,-6)[/tex]
[tex]N" = (-4,-2)[/tex]
Mona wants to buy carpet for a floor in her house. The floor is rectangular with a width of 5 m and a length of 8 m. Two shops sell carpet with the prices shown below. How much will Mona save by going to Carpet World ?
Answer:
Mona will save a total of $7 by going to Carpet World.
Step-by-step explanation:
First, we need to calculate the total area of the floor by multiplying the width by the length...
5m * 8m = 40m
Now we calculate the amount that it would cost to buy the carpet from each of the establishments. For the first establishment, we can buy 16[tex]m^{2}[/tex] and get the next 8[tex]m^{2}[/tex] half off and that would leave another 16[tex]m^{2}[/tex] at full price. The second establishment we have a 5% off (0.95 of official price) for every 8[tex]m^{2}[/tex], since out total area is 5 times this amount then our total will have a 5% off.
Establishment 1: (16[tex]m^{2}[/tex] * 2.20) + (8[tex]m^{2}[/tex] * 1.10) + (16[tex]m^{2}[/tex] * 2.20) = $79.20
Establishment 2: (40[tex]m^{2}[/tex] * 1.90) * 0.95 = $72.20
Difference: 79.20 - 72.20 = $7
Mona will save a total of $7 by going to Carpet World.

E is the midpoint of AC, and DE||BC, find the length of DE.
Answer:
3.2333 (repeated)
3.23 (rounded

A company rents bikes. The price, p, in dollars, to rent a bike for h hours can be
found using the formula p(n)= 14 + 3h. What is the price to rent a bike for
5 hours?
Answer: 29$
You have to replace h by 5 because we need to know the price for 5hours then you just add everything . I wish it helped you :)
The price to rent a bike for 5 hours by using the equation p(h)= 14 + 3h will be $29.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.
A company rents bikes. The price, p, in dollars, to rent a bike for h hours can be found using the formula p(h)= 14 + 3h.
Then the price to rent a bike for 5 hours will be given as,
p(5) = 14 + 3(5)
Simplify the equation, then we have
p(5) = 14 + 15
p(5) = 29
The price to rent a bike for 5 hours will be $29.
