Respuesta:
27,22 metros
Explicación paso a paso:
Dado :
Sombra del poste = 21 metros
Altura de la persona = 1,75 metros
Sombra de la persona = 1,35 metros
Altura del poste =?
Usando la relación:
Altura de la persona / sombra de la persona = altura del poste / sombra del poste
1,75 / 1,35 = x / 21
Cruz multiplicar
1,35 * x = 1,75 * 21
x = (1,75 * 21) / 1,35
x = 27,22

Two blocks of wood are shaped as a right rectangular prism the smaller block has a length of 9 cm a width of 3 cm and a height of 7 cm the dimensions of the larger block are double the dimensions of the smaller block what is the volume of the larger block of wood
Answer:
1512 cm^3
Step-by-step explanation:
the small ones dimentions are 9 by 3 by 7
if you double that then it is 18 by 6 by 14
to figure out the volume you have to multiply all the numbers together
and you get 1512 cm^3
Make A the subject of the formula r=√А/3
Answer:a = 9 r^2
Step-by-step explanation:
We need to make a subject of the formula given r = square root a / 3
Given r = √a / 3 -------------1
Now we can find a.
Squaring the given equation 1 we get
So r^2 = (√a / 3)^2
So r^2 = a / 9
To three decimal places, find the value of the first positive x-intercept for the function f(x) = -2cos(x + 1). (6 points)
0.571
1.571
-1.081
-2.571
PLEASE HELP URGENT I AM TAKING IT NOW
I'm not 100% sure about this because this unit confused me but...
if you put it in your graphing calculator or in desmos, you can see that the first positive x -intercept (which is a point that is on the x-axis) is somewhere around one but it's not 1.571!! (other person is wrong!)
that point is (0.571, 0) so it's the first option
Apples cost $1.99 per pound. How much do 314 pounds of apples cost? $ How much do x pounds of apples cost? $ Clare spent $5.17 on apples. How many pounds of apples did Clare buy? pounds
Answer:
1. $624.86
2. 1.99x
3. 2.6 pounds
Step-by-step explanation:
1. Multiply 1.99 by 314 to get 624.86
2. With the equation 1.99x, you can substitute any variable into it and it will hold true.
3. Divide 5.17 by 1.99, the price, and you get 2.597 pounds, which rounds to 2.6
la torre de pisa esta inclinada de modo que su pared lateral forma un triangulo rectangulo de catetos 7 metros y 24metros ¿cuanto mide la pared lateral?
Answer:
La torre de pisa esta inclinada de modo que su pared lateral forma un triangulo rectangulo de catetos 5mtrs y60mtrs cuanto mide el otro lado de la torre !
RESOLVEMOS POR EL TEOREMA D EPITÁGORAS
Primero lado = 5 m
Segundo lado = 60 m
Lo que mide el otro lado es = x
Calculamos:
h² = a² + b²
h² = (5 m)² + (60 m)²
h² = 25 m² + 3600 m²
h² = 3625 m²
h = √3625 m²
h = 60,20 m
Rpt. El otro lado mide 60,20 m aproximadamente

0.4 repeating as a fraction for a mixed number
Answer:
Step-by-step explanation:
1.Rewrite the decimal number as a fraction with 1 in the denominator
2.Multiply to remove 1 decimal places. Here, you multiply top and bottom by 101 = 10
3.Find the Greatest Common Factor (GCF) of 4 and 10, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 2,
so the answer is
0.4= 2/5
A circular flower bed is 23 m in diameter and has a circular sidewalk around it that is 4 m wide. Find the area of the sidewalk in square meters. Use 3.14 for π.
Answer: 244.92 m
Step-by-step explanation:
The area of a circle is pir^2. First you will need to find the area of the concrete and subtract the area of the flower bed from that amount. The concrete is 3 feet wide so you will add that to 11.5 (half of the flower bed diameter) to find the radius. 14.5^2 pi is the entirety of the area. Then subtract 11.5^2 pi for the area of the concrete.

Please help! 30 points and crown! A diagonal of a cube measures StartRoot 750 EndRoot cm. The diagonal of a face measures StartRoot 500 EndRoot cm.
In centimeters, what is the length of an edge of the cube? Round the answer to the nearest tenth.
? centimeters
Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.

Answer: dont get the question sry
Step-by-step explanation:
Answer:
y =-4
x = 1
Step-by-step explanation:
Add the two equations
4x - y + 6x + y = 8 + 2 add like terms
10x = 10 divide both sides by 10
x = 1 now to calculate y replace x in first equation by 1
4x - y = 8
4 - y = 8 subtract 4 from both sides
-y = 4 and y = -4

Find the area of quarter circle with the radius of 10
Answer: 78.5
Step-by-step explanation:
Formula: A=pi*r^2 or Area = 3.14*radius squared (by two)
A = 3.14*10^2
A = 3.14*100
A = 314
Divide it by 4, because it's a quarter of the circle: A = 314/4
A = 78.5
Answer: 78.5

verify the following
i.[ -3/4]3 = -27/64
ii. [-2/3]6 = 64/ 729
Answer:
The relationships are correct and valid
Step-by-step explanation:
The correct question is as follows;
Verify the following
i.[ -3/4]^3 = -27/64
ii. [-2/3]^6 = 64/ 729
We have the solution as follows;
i) we have;
(-3/4)^3
That means ;
-3^3 = -3^3 = -27
4^3 = 64
so;
(-3/4)^3 = -27/64
ii) (-2/3)^6
(-2)^6 = 64
3^6 = 729
Thus;
(-2/3)^6 = 64/729
