Answer:

40 km/h

Step-by-step explanation:

rate of change of distance = speed

speed = distance/time

speed = (400 km)/(10 h)

speed = 40 km/h

Rate of change of distance is also known as speed.

Given,

Distance (s) = 400km = 400 × 1000m = 400,000m

Time (t) = 10h = 10 × 3600s = 36,000s

We know that,

Speed (v) = Distance/Time

=> v =  \frac{s}{t}  \\ => v =  \frac{400000m}{36000s}  \\ => v =  \frac{400m}{36s}  \\ => v =  \frac{100m}{9s}  \\ => v =  \frac{100}{9}m {s}^{ - 2}   \\

Figure AFigure B
Solnce55 [7]

Using the given information, the area of figure B is 315 ft²

<h3>Calculating Area </h3>

From the question, we are to calculate the area of figure B

In the given diagram, figure B is made up of a triangle and a square

∴ Area of figure B = Area of triangle + Area of square

Area of triangle = \frac{1}{2} bh

Where b is the base

and h is the height

Area of square = l^{2}

Where l is the length of a side

In the diagram,

l = b = 15 \ ft

h =12 \ ft

∴ Area of figure B = (\frac{1}{2}\times 15 \times 12) + 15^{2}

∴ Area of figure B = (15×6) + 225

∴ Area of figure B = 90 + 225

∴ Area of figure B = 315 ft²

Hence, the area of figure B is 315 ft²

The time to complete an exam is approximately Normal with a mean of 70 minutes and a standard deviation of 10 minutes. Using the
MatroZZZ [7]

Answer:

16% of students will complete the exam in less than 60 minutes

Step-by-step explanation:

The Empirical Rule(68-95-99.7) states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 70

Standard deviation = 10

What percentage of students will complete the exam in less than 60 minutes

60 = 70-10

So 60 is one standard deviation below the mean

By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean, that is, from 60 to 80 minutes. The other 100-68 = 32% is outside this interval. Since the normal distribution is symmetric, 16% of those are below 60 and 16% of those are above 80.

16% of students will complete the exam in less than 60 minutes

I need help with #10!
DiKsa [7]

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that  In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

x+3

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

x+3=\frac{3x}{2}

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6
