To prepare for a bake-off, Luis used 590 grams of flour each day for 3 weeks. How many kilograms did Luis use in those 3 weeks?

Thepotemich [5.8K]

Answer: $12.39\ kg$

Step-by-step explanation:

Given

Luis used 590 gm of flour each day

If he continues to use it for 3 weeks

A week has 7 days; so 3 weeks have 21 days

The flour used in 21 days

$\Rightarrow 21\times 590\\\Rightarrow 12,390\ g\ \text{or}\ 12.39\ kg$

Thus, $12.39\ kg$ of flour is used in 3 weeks

2. A scuba diver was exploring a reef 77.5 m below sea level. The diver ascended to the surface at a rate of 12.5 m/min. (a) Wri

Elodia [21]

Answer:

77.5 = 12.5t

6.2 mins.

Step-by-step explanation:

The scuba diver was at the sea bed from where the water surface is at 77.5 m height. The ascending speed of the diver is 12.5 m/minute.

a. If the diver take t minutes to reach the water surface, then the equation that models the situation is

77.5 = 12.5t ......(1)

b. If we consider the sea bed as a reference level i.e. zero height, then the sea surface will be at 77.5 m height.

Therefore, in that case, it is reasonable to write the distance 77.5 m as a positive number.

c. Solving the equation (1), we get, t = 6.2 minutes.

So, the diver will take 6.2 mins to reach the surface. (Answer)

What's the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8)? ANSWERS: A)

zavuch27 [327]

Answer:

B) y = x + 2

Step-by-step explanation:

Coordinates of point C = $(x_1,y_1)=(6,-12)$

Coordinates of point D= $(x_2,y_2)=(10,-8)$

To find the equation of segment CD

Formula : $y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

Substitute the values in the formula :

$y-12=\frac{-8+12}{10-6}(x-6)$

y-12=x-6

y=x+6

When two lines are perpendicular to each other the product of their slopes is -1

Let the slope of perpendicular line be x

So, -1 \times x = -1

So, x =1

General equation : y = mx+c

So, Option B has slope = 1

So,the equation of the line that's a perpendicular bisector of the segment connecting C (6, –12) and D (10, –8) is y = x + 2
