Answer:

D. y = 76x

Step-by-step explanation:

First you find the gradient, by using the gradient formula

rise over run

380 - 228

---------------- <- division sign

5 - 3

152/2 = 76

Hence y = 76x + c

Find c by subbing points in. I am going to use this as an example (5, 380)

380 = 76(5) + c

380 -380 = c

c = 0

Hence, y = 76x

mariarad [96]

Answer: 35.4 feet.

Step-by-step explanation:

Given data:

Height of the roof = 24 feet

Height of the ladder = 26 foot

Solution:

c^2 = a^2 + b^2

a = 24

b = 26

c^2 = 24^2 + 26^2

c = √576 + 676

c = √1252

c = 35.4 feet

The foot of the ladder is 35.4 foot away from the top of the ladder.

Nidhi is thinking of a number n, and she wants her sister to guess the number. Her first clue is that eight less than three time

Dmitriy789 [7]

Answer:

The range of numbers that Nidhi might be thinking of is between 3 and 9.

Step-by-step explanation:

We are given that Nidhi is thinking of a number n, and she wants her sister to guess the number.

Her first clue is that eight less than three times her number is between one and nineteen.

Let the number Nidhi is thinking be 'n'.

So, eight less than three times her number means that;

$(3\times \text{n}) - 8 = 3\text{n}-8$

Now, according to the question; the above equation is between one and nineteen, so;

$1< 3\text{n}-8 < 19$

Adding 8 to the whole expression;

$1+8< 3\text{n}-8 +8< 19+8$

$9< 3\text{n}< 27$

Dividing the whole expression by 3;

$\frac{9}{3} < \frac{3\text{n}}{3} < \frac{27}{3}$

$3< \text{n}< 9$

Hence, the range of numbers that Nidhi might be thinking of is between 3 and 9.
