Hiroto reduces a rectangular photograph by 0.5 by scanning it onto his computer. The image on the screen measures 3 inches by 5
AnnyKZ [126]

Answer:

<em>The correct option will be:   Rectangle C (Width= 6 and Length= 10)</em>

Step-by-step explanation:

Suppose, the length of the original photograph is x inches and width is y inches.

Hiroto reduces the photograph by 0.5 by scanning it onto his computer.

So, the <u>length of the scanned image</u> =0.5x inches <u>and width</u> =0.5y inches.

Given that, the length and width of the image on the screen are 5 inches and 3 inches respectively. That means.........

0.5x=5\\ \\ x=\frac{5}{0.5}=10\\\\\\ and\\ \\ 0.5y=3\\ \\ y=\frac{3}{0.5}=6

So, the rectangle C represents the original photograph, which has width as 6 inches and length as 10 inches.

ivolga24 [154]

Answer:

4.9 m

Step-by-step explanation:

Resolvemos la pregunta anterior usando la función trigonométrica de seno

sin θ = Opuesto / Hipotenusa

θ = 78 °

Hipotenusa = Longitud de la escalera = 5 m

Opuesto = Distancia sobre el suelo = x

sin 78 = x / 5m

Multiplicar cruzada

x = sin 78 × 5 m

x = 4.8907380037m

Aproximadamente

= 4.9 m

Who do I find the percent of a number
expeople1 [14]
Always divide by 10 first, for example; if it was 10% of 20 you would divide 20 by 10 to get 2. If it was 20% of 40 you would divide by 10 to get 4 then times by 2 to get 8.
