Since Beth was born the population of her towns has increased at a rate of 850 people per year. On beths 9th birthday the total

Lana71 [14]

Answer:

313,600

Step-by-step explanation:

Let t represent number of years after Beth's 9th birthday.

We have been given that since Beth was born the population of her towns has increased at a rate of 850 people per year. So number of people increased in t years would be $850t$ .

We are also told that on Beth's 9th birthday the total population was nearly 307,650. This means that t-intercept is 307,650.

The population of town t years after Beth's birthday would be $P(t)=850t+307,650$ .

To find population on Beth's 16th birthday, we will substitute $t=7$ in our equation as Beth's 16th birthday would be 7 years after 9th birthday.

$P(t)=850(7)+307,650$

$P(7)=5950+307,650$

$P(7)=313,600$

Therefore, the population on Beth's 16th birthday would be 313,600.

What is H in the algebraic expression H+340÷30=25

disa [49]

Answer:

H = 13.67

Step-by-step explanation:

Given:

The the algebraic expression is

$H + \frac{340}{30} = 25$

We need to write the above equation for h.

Solution:

$H + \frac{340}{30} = 25$

First we divide the fraction part of the equation by common factor 10.

$H + \frac{34}{3} = 25$

Subtract both side of the equation by $\frac{34}{3}$ .

$H + \frac{34}{3}-\frac{34}{3} = 25- \frac{34}{3}$

$H = 25- \frac{34}{3}$

To write 25 as a fraction with a common denominator, multiply by $\frac{3}{3}$ .

$H = 25\times \frac{3}{3}- \frac{34}{3}$

$H = \frac{25\times3}{3}- \frac{34}{3}$

$H = \frac{75}{3}- \frac{34}{3}$

$H = \frac{75-34}{3}$

$H = \frac{41}{3}$

$H = 13.67$

Therefore the value of H is 13.67.

A triangle has two sides of lengths 7 and 9.what value could the length of the third side be?

Diano4ka-milaya [45]

The side length has to be between 2 (=9-7) and 16 (=9+7). In both these corner cases the triangle will have collapsed to a line.

So the correct answers are B,C,D and E, and F is a corner case. Theoretically I suppose you have to count F in as a valid answer.

When she was younger, Mary had to look up at a 68 degree angle to see into her father's eyes whenever she was standing 15 inches

jekas [21]

Answer:

69 INCHES

Step-by-step explanation:

Given that :

Height of father's eye above the flat ground :

Kindly check attached picture for diagram:

To obtain the value of h ; we can use Pythagoras rule ;

Tan θ = opposite / Adjacent

Tan 48 = h / 15

15 tan 48 = h

37.126302 = h

h = 37.

Hence, height of father's above the flat ground :

h + 32 = 37 + 32= 69 inches
