The sea floor is 104 feet below sea level. Katy is 28 feet below sea level. She is moving downward at a rate of 4 feet per minute. Colin used the following calculation to determine how long it will take Katy to reach the sea floor. Is he correct? Explain.

Answers

Answer 1

Answer:

19 minutes

Step-by-step explanation:

Taking the sea level as the reference point, the values of depths to be considered can be determined as follows;

Total depth from sea level to the sea floor = 104 feet

Katy's depth from the sea level (depth covered) = 28 feet

Katy's distance to the sea floor = 104 - 28

                                          = 76 feet

Katy's distance to the sea floor = 76 feet

But Katy moves at a rate/ speed of 4 feet per minute;

So that,

speed = [tex]\frac{distance}{time}[/tex]

time = [tex]\frac{distance }{speed}[/tex]

       = [tex]\frac{76}{4}[/tex]

       = 19

time = 19 minutes

Therefore it would take Katy 19 minutes to reach the sea floor.

Answer 2

Answer:

Step-by-step explanation:

No, Colin is not correct. He needs to subtract first to get the total distance and then divide by the rate. He should have put parentheses around 104–28 and then divided by 4 to get the answer of 19 minutes.

Si colocan en 16 pisos, 16 ladrillos. ¿Cuántos ladrillos pusieron en total?. (expresarlo en forma de potencia)

Answers

Answer:

Númer total de ladrillos= 256

Step-by-step explanation:

Dada la siguiente información:

Total de pisos= 16

Total de ladrillos por piso= 16

Para calcular cantidad de ladrillos en total, tenemos que usar la siguiente formula:

Número total de ladrillos= total de ladrillos^2

Número total de ladrillos= 16^2

Númer total de ladrillos= 256

En este caso lo hace al cuadrado por que la cantidad de pisos y ladrillos por piso es la misma. Sino, es mejor expresarlo como una multiplicación.

A=38000(1+0.0825*20)

A=38000(1+1.65)

A=38000*(2.65)

A=$100,700

Hence in 20 years she will pay $100,700

Answer:

a. 33 sqft

Step-by-step explanation:

The figure is made of two non-overlapping triangles, so the total area is the sum of the areas of the two triangles

Area of a triangle is 1/2(bh) where b = base length and h = height (b and h must be perpendicular to each other)

The top triangle has b = 6 and h=8, so A=1/2(6)(8) = 1/2(48) = 24

The bottom triangle has b=6 and h=3, so A=1/2(6)(3)=1/2(18) = 9

Total area is sum of these two or 24 + 9 = 33
