Si una escalera de bomberos de 37 metros de longitud,se apoya en la pared de un edificio,poniendo el pie de la escalera a 12 metros del edificio, ¿que altura, en metros, alcazan la escalera?
Answer:
La escalera alcanza 35 metros de altura.
Step-by-step explanation:
La altura que alcanza la escalera se puede calcular usando Pitágoras:
[tex] L^{2} = B^{2} + A^{2} [/tex]
En donde:
L: es la longitud de la escalera = 37 m
B: es la distancia del pie de la escalera al edificio = 12 m
A: es la altura =?
Entonces, la altura es:
[tex] A = \sqrt{L^{2} - B^{2}} = \sqrt{(37 m)^{2} - (12 m)^{2}} = 35 m [/tex]
Por lo tanto, la escalera alcanza 35 metros de altura.

A photo album costs $10.49 before discount and tax.
There is a 30% off discount. After the discount, a 6%
sales tax is added.
What is the total after discount and tax?
Answer:
Total after tax and discount is $7.78
Step-by-step explanation:
(10.49×0.3)= 3.15
10.49 - 3.15 = 7.34
(7.34×0.06)= 0.44
7.34 + 0.44 = 7.78

HELP i need to find area AND perimeter there is a triangle and a rectangle
Answer:
perimeter of this figure is = 54 cm
and area of traingle is = 1/2*base *height
so = 1/2*8*6
=. 24cm*cm
and area of rectangle = length * breadth
area = 112cm*cm
so total area = 112+ 24 = 136cm*cm
hope it helps and your day will full of happiness
Answer:
138 cm^2 = Area . 54 cm = Perimeter
Step-by-step explanation:
Find the area of the triangle- b * h = A
2
8 * 6 = A
2
48/2 = A
24 = A
Find the area of rectangle- l * w = A
16 * 7 = A
112 = A
Add the areas together. 24 + 112 = 136 cm^2
Perimeter is adding up all the sides. s + s + s + s + s
16 + 7 + 8 + 10 + 13 = 54 cm

alice is making a necklace she has a chain that is 400 mm long she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain about how much of the 400 mm chain is left withoutbeads?
388 mm
270 mm
230 mm
129 mm
Answer: I believe its D
The 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain option (D) is correct.
What is an arithmetic operation?Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them. Addition, subtraction, multiplication, and division are the four basic math operations.
We have:
The total length of the necklace chain = 400 mm
Alice put 40 Nos 1.7 mm beads
Length for this = 40×1.7 = 68 mm
Alice put 27 Nos 6.5 mm beads
Length for this = 27×6.5 = 175.5 mm
Alice put 8 Nos 3.4 mm beads
Length for this = 8×3.4 = 27.2 mm
Total length occupied = 68+175.5+27.2 = 270.7 mm
The length of 400 mm chain is left = 400 - 270.7 = 129.3 ≈ 129 mm
Thus, the 129 mm length is left out of the 400 mm total length of the chain if she puts forty 1.7 mm beads twenty-seven 6.5 mm beads and eight 3.4 mm beads on the chain.

bill paid $35.99 in tax on a laptop that cost $449.99. about what percent sales tax did bill pay
Answer:
Bill paid about 7% sales tax.
Step-by-step explanation:
First, to find the value of 1%, I divided $449.99 by 100, which gave me 4.4999. I then divided the amount paid for tax by the value of 1%. That;s $35.99 ÷ $4.4999 = 7.199439887977596. Obviously, you can't put that in your math homework, plus the question says "about," so you're going to round. Because the first number after the decimal point is less than five, you round down. Therefore, the sales tax is about 7%.

x=4
Step-by-step explanation:
First we Divide both sides by 4 so we can just get x
For example
4x=16
x=4 We divided both sides by 4 because we need to get x and the reason why we also divided 16 by 4 is because what you do to one side you do to the other to keep the values consistent
