Answer:

43 2/3°
92 1/3°
44°

Step-by-step explanation:

The sum of angles in any triangle is 180°.

(x +45) +(2x +95) +(3x +48) = 180

6x +188 = 180 . . . . . . . . collect terms

6x = -8 . . . . . . . . . . . subtract 188

x = -4/3 . . . . . . . . divide by 6

Then the angles are ...

x +45 = -4/3 +45 = 43 2/3°

2x +95 = 2(-4/3) +95 = 92 1/3° . . . . the obtuse angle

3x +48 = 3(-4/3) +48 = 44°

vivado [14]

Answer:

Arnold descended a distance of 5,250 ft after his parachute opened

Step-by-step explanation:

Here in this question, we want to know the distance Arnold descended after his parachute opened.

Mathematically, we know that distance = speed * time

In this case;

The speed is the rate at which he descended = 70 ft per second

Now the time is 1 minute and 15 seconds; since 1 minute is 60 seconds, then 1 minute and 15 seconds is 60 + 15 = 75 seconds

So what we are saying is he descended at a rate of 70 ft per second for 75 seconds

Thus, his distance of descent will be 70 ft per second * 75 seconds = 5,250 ft

1. A student invests $500 in a savings account that earns 4% interest per

bixtya [17]

Answer:

The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$

Step-by-step explanation:

A student invests $500 in a savings account

Principal = $500

Rate of interest = 4% = 0.04

We are supposed to find equation can be used to determine the amount of money S(t) that her savings account has after t years

Formula : $A=P(1+r)^t$

Where A is the amount after t years =S(t)

t = time

r = rate of interest in decimals =0.04

P = Principal=500

Substitute the value in the formula :

So, $S(t)=500(1+0.04)^t$

$S(t)=500(1.04)^t$

Hence The equation can be used to determine the amount of money S(t) that her savings account has after t years is $S(t)=500(1.04)^t$

During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 7

kondaur [170]

Answer:

13 centimeters per day.

Step-by-step explanation:

We have been given that during summer, the water level of the river increased by 78 centimeters in 6 days. We are asked to find the water level increase rate in centimeters per day.

To find the water level increase rate per day, we will divide total increase by total days as:

$\text{Water level increase rate per day}=\frac{78\text{ cm}}{6\text{ days}}$

$\text{Water level increase rate per day}=\frac{13\text{ cm}}{\text{ day}}$

Therefore, the water level increase rate is 13 centimeters per day.
