ExtremeBDS [4]
To find the hypotenuse of the triangle
you use the length of the legs
Plug it into the Pythagorean Theorem

so a^{2} +  b^{2} =  c^{2}

a^{2}  is one of the legs

and 

b^{2}  is the other leg

then 

c^{2}  is the hypothenuse

3. A square metal plate has a density of 10.2 g/cm3 and weighs 2.193 kg.
MakcuM [25]

Answer:

215 cm³

8.6 cm

Step-by-step explanation:

given,

density = 10.2 g/cm³

mass = 2.193 kg = 2193g

a. Volume = mass / density

=2193 / 10.2

= 215 cm³

b. given that base area = 25cm²

volume = base area x thickness

thickness = volume / base area

= 215 / 25

= 8.6 cm

Ji-Hun and Kana are running a marathon. Due to the volume of people running, the starts occur in waves. Kana starts at 9:35 a.m.
iris [78.8K]

Answer:

23.52 miles

Step-by-step explanation:

Let us find the number of miles that they would have run.

Kana starts at 9:35 a.m. and runs at an average rate of 7 mph.

Let the time she has spent so far be t.

Speed is given as:

s = d / t

where d = distance and t = time

=> d = s * t

Therefore, for Kana:

d = 7 * t = 7t _____________(1)

Ji-Hun starts at 10:00 am (25 minutes after Hannah) and runs at an average rate of 8 mph.

25 minutes = 25/60 hour = 0.42 hour

So, his time (compared to Kana's) is t - 0.42.

therefore, for Ji-Hun:

d = 8 * (t - 0.42)

=> d = 8t - 3.36 ____________(2)

Equating (1) and (2):

7t = 8t - 3.36

=> 8t - 7t = 3.36

t = 3.36 hours

Therefore, let us find d:

d = 7 * 3.36 = 23.52 miles

So, Ji-Hun will catch up to Kana after 23.52 miles.

Noah was assigned to make 64 cookies for the back sale. He made 125% of that number. 90% of the cookies he made were sold. How m
Serhud [2]

Answer: 16

Step-by-step explanation:

100% is 64 and 1% of 64 is 6.4 and if you multiply 6.4 times 25 is 160 so 125% is 160 so 90% of 160 is 144 so 160-144 is 16

A scatterplot has a positive, linear correlation. Which statement is true about the relationship between the x- and y-
krek1111 [17]

Answer:

Hence, option: A is the correct answer.

A. As the x-values increase, the y-values tend to increase.

Step-by-step explanation:

It is given that:

A scatterplot has a positive, linear correlation.

By positive we means that as the x-value increases the y-value also keeps on increasing and by linear relation we mean that it increases somewhat by a constant amount so that the we get a line of best fit.

Hence, the statement which  is true about the relationship between the x- and y-values is:

A. As the x-values increase, the y-values tend to increase.
