Answer:

The answer is D

Step-by-step explanation:

We are going to try all the answers on the choices to find the right choice.

<u>Choice A:</u>

We will start with 0:

-(5*0)/4+90=90

That is correct lets try 16:

-(5*16)/4+90=70

It can be seen that choice A is incorrect.

<u>Choice B:</u>

We tried 0 in above and it gave 90. So, we will start with 40:

-(3*40)/8+75=60

It can be seen that choice B is incorrect.

<u>Choice C:</u>

We tried 40 in above and the function gave 60.

It can be seen that choice C is also incorrect.

<u>Choice D:</u>

We tried 40 in above and the function gave 60. Therefore, we will start with 160:

-(3*160)/8+75=15

Lets try the last number 200:

-(3*200)/8+75=0

It can be seen that choice D is correct.

Substitute the values of x from each table and see which values fit 

For example in table d  when x = 40 y = (-3/8)*40 + 75  =  60    which is the result  given in table d

The other 2 values also fit  table d

Answer is table d.

HELP URGENT I WILL GIVE 20 POINTS
Lunna [17]

h = 9.2 cm

Solution:

Base of smaller triangle = 5 cm

Height of smaller triangle = 2.3 cm

Base of larger triangle = 15 cm + 5 cm = 20 cm

Height of larger triangle = h

$\frac{2.3}{5}=\frac{h}{15+5}

$\frac{2.3}{5}=\frac{h}{20}

Multiply by 20 on both sides.

$20 \times \frac{2.3}{5}=\frac{h}{20} \times 20

$\frac{46}{5}=h

9.2 = h

So that Ryan should have add 15 and 5 to get a denominator of 20 on the right sides of the first line. Doing so gives the correct value, h = 9.2 cm.
