Answer:
x ≈ 59.0°
Step-by-step explanation:
using the tangent ratio in the right triangle
tanx = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{30}{18}[/tex] , then
x = [tex]tan^{-1}[/tex] ( [tex]\frac{30}{18}[/tex] ) ≈ 59.0° ( to the nearest tenth )

Matt went on a bike ride of 60 miles. He realized that if he had gone 6 mph faster, he would have arrived 5 hours sooner. How fast did he actually ride
Matt travelled on a bike and cover a distance of 60 miles . If he had gone 6mph faster, he would have arrived 5 hours. Therefore, the actual rate is 6 mph.
What is rate?Rate is the ratio between two related quantities in different units.
He went on a bike ride of 60 miles.
He realized if he had gone 6 miles per hour he would have arrived 5 hours earlier.
The speed he actually ride can be calculated as follows:
let
x = speed he actually ride
y = time he arrived
Therefore,
speed = distance / time
x = 60 / y
On, the other hand his permutation is as follows:
x + 6 = 60 / y - 5
(x + 6)(y - 5) = 60
since, x = 60 / y we can substitute it in the equation
(60 / y + 6)(y - 5) = 60
60 - 300 / y + 6y - 30 = 60
- 300 / y + 6y = 60 - 30
- 300 / y + 6y = 30
6y² - 300 = 30y
6y² - 30y - 300 = 0
y² - 5y - 50 = 0
y² + 5y - 10y - 50 = 0
y(y + 5) -10(y + 5) = 0
(y - 10)(y + 5) = 0
y = 10 or -5
we cannot use negative values.
Therefore,
y = 10
x = 60 / y = 60 / 10 = 6 miles per hour
He actually rode 6 miles per hour.
If he went 6 mph faster that would be 6+6 = 12 mph
If he arrived 5 hrs sooner that would be 10 - 5 = 5 hrs

If the population of Alaska in 2000
was 622,000 and 733,000 in 2020,
assuming exponential growth, what
would the population be in 2050?
[ ? ] people
The number of people by the year 2050 is obtained as 927915 people.
What is the population in 2050?We know that population is an exponential growth problem in this case. We have to apply the formula;
P = Poe^rt
P = population at time t
Po = Initial population
r = population growth rate
t = time taken
Now;
We have to use the relation to find the growth rate as follows;
733,000 = 622,000 e^20r
733,000/622,000 = e^20r
1.178 = e^20r
ln(1.178) = 20r
r = ln(1.178)/20
r = 0.008
Now;
In the year 2050, we would have;
P = 622,000 e^50 * 0.008
P = 927915 people

Answer:
Step-by-step explanation:
Sum of exterior angles of any Polygon = 360°
23. x + 65 + 106 + 78 = 360
x + 249 = 360
{To find the value of x, subtract 249 from both sides}
x = 360 - 249
x = 111°
_________________________________________
24. x + x + 59 + 48 + 50 + 39 + 58 = 360
2x + 254 = 360
2x = 360 - 254
2x = 106
x = 106 ÷ 2
x = 53°
____________________________________________
25. 2x + 3x + 44 +85 + 71 = 360
5x + 200 = 360
5x = 360 - 200
5x = 160
x = 160 ÷ 5
x = 32°
_______________________________________________
26. x+ 2x + 77 + 40 + 45 = 360
3x + 162 = 360
3x = 360 - 162

Answer:
11.80
Step-by-step explanation:
The $11.80 will be her July finance charge option (c) is correct.
It is given that Elizabeth’s credit card computes her finance charges using the previous balance method and a 30-day billing cycle.
It is required to find the July finance charge.
What is APR?It is defined as the annual percentage rate that represents the yearly interest rate on the borrowing.
We have a principal amount = $969.26
APR = 14.61 %
Per month percent rate = [tex]\frac{14.61}{12}[/tex] ⇒ 1.2175 %
We can calculate the finance charge from the given formula:
Finance charge = Principal value×rate×Time
= 969.29×1.2175%×1
[tex]= 969.29\times\frac{1.2175}{100}\times1[/tex]
= $11.80
Thus, the $11.80 will be her July finance charge.

Two independent variables that can affect the cost of the supplies are:
x = number of pencils bought.y = number of notebooks bought.What is an independent variable?An independent variable is a variable that can change freely.
For example in the given situation, we could define the independent variables:
x = number of pencils bought.y = number of notebooks bought.Notice that these variables are independent because these don't depend on each other.
Then if each pencil costs A, and each notebook costs B, the cost function will be:
C(x, y) = A*x + B*y
So there you have two independent variables that affect the cost of the supplies.

Step-by-step explanation:
What makes this undefined.
The expression is undefined when x=3 or -3
Solution:An expression is undefined when it's divided by 0.In order to make the denominator equal 0, we need to subtract 9-9. Notice that x is squared.So x times itself should equal 9. What number is it?That's right, 3.So we have9-(3)^2=9-9=0There's also another solution: x=-3 (-3•(-3)=9Hope it helps.
Do comment if you have any query.
Answer: The expression is undefined when x is 3 or -3
Step-by-step explanation:
The denominator of a fraction can never be 0 because you cannot divide by 0. So all we have to do is determine the value of x when the denominator is equal to 0.
[tex]9-x^{2} =0\\[/tex]
We want [tex]x^2[/tex] to be positive so divide everything by -1
[tex]9-x^{2} =0\\\\\frac{9-x^{2}}{-1}=\frac{0}{-1} \\-9+x^2=0\\x^2-9=0[/tex]
Use difference of two squares (DOTS) to factor
[tex]x^2+9=0\\(x+3)(x-3)=0[/tex]

Answer:
arc RS = 60°
Step-by-step explanation:
the secant- secant angle P is half the difference of ots intercepted arcs, that is
40° = [tex]\frac{1}{2}[/tex] (QT - RS ) ← multiply both sides by 2 to clear the fraction
80° = QT - RS
80° = 140° - RS ( subtract 140° from both sides )
- 60° = - RS ( multiply both sides by - 1 )
60° = RS
Omar and Ted have a total of 25 books. Omar has 5 less than twice the number of books Ted has. Use a graph to find how many books each boy has. y
Answer:
Ted has 10 books and Omar has 15 books
Step-by-step explanation:
Hey there!
In order to find how many books each of the boys have, we can make a system of equations
First equation: O+T=25
Second equation: O=2T-5
After making the equations, you can use substitution by plugging in 2T-5 For O in the first equation:
2T-5+T=25
Simplify LHS
3T-5=25
Take 5 to the other side
3T=30
Divide by 3 on both sides to get T by itself
T=10
So this means that Ted has 10 books
Now we can plug this into the second equation
*note that you can plug 10 into the first equation too*
O=2(10)-5
Simplify RHS
O=20-5
Combine like terms
O=15
This means that Omar has 15 books
So, Ted has 10 books and Omar has 15 books

Solve this linear equation 2.6(.5.5-12.4=127.92
Answer:
First we must distribute the 2.6 to everything inside the ()
The new equation would then be 14.3p-32.24 = 127.92
Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.
The new equation would then be 14.3p = 160.16
Then you divide each side of the = by 14.3, that way the p becomes isolated. 14.3p/14.3 = 160.16/14.3
Then you're left with p=11.2
