In the figure below, angle 1=(x+42)° and angle 2=2x° Find the angle measures.
Answer:
Step-by-step explanation:
Fg=14a+1, Fm=14.5 what is a
The value of a is 2.
A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment FG, where the length of line segment FG refers to the distance between its endpoints, F and G.
Given that M is the midpoint of FG
FG = 14a + 1 and FM = 14.5
FG = FM + MG
Since M is the midpoint of FG, So FM = MG
FG = FM + FM
FG = 2FM
Substitute the values of FG = 14a + 1 and FM = 14.5,
14a + 1 = 2(14.5)
14a + 1 = 29
14a = 28
a = 28/14
a = 2
Therefore, the value of a is 2.

Which steps must you take to convert 15,840 feet per minute into miles per minute? Check all that apply.
Write a conversion factor with miles in the numerator and feet in the denominator.
Write a conversion factor with feet in the numerator and miles in the denominator.
Multiply 15,840 by 5,280.
Divide 15,840 by 5,280.
Cancel units of feet.
Answer:
The factor which is used to convert feet per minute into miles per minute is:
1 ft per minute=0.000189 miles per minute.
( since, 1 ft.= 0.000189 miles )
Step-by-step explanation:
Conversion factor--
A conversion factor is a factor which is used to convert one unit to another by multiplication or division by a specified number.
We know that:
1 miles= 5280 ft.
This means that:
1 ft.=1/5280 miles
i.e. 1 ft.= 0.000189 miles.
Hence, 1 ft per minute=0.000189 miles per minute.

Vectors! A ship can sail at 30 km/h in still water. The ship heads due north. The water current is flowing at 10 km/h due east.
a) What is the actual velocity of the ship?
b) What direction does the ship sail in?
Answer:
a) 31.62 km/hb) 18.4° NE======================
GivenThe speed of the ship = 30 km/h,The speed of the current = 10 km/hA) Actual velocity is found as the sum of two vectors representing the two velocities.
Since the directions are at 90° (N and E), we will use Pythagorean to find the actual velocity.
[tex]v = \sqrt{30^2+10^2}=\sqrt{1000}= 31.62[/tex] km/h (rounded)b) Let the direction the ship sails in is x. Use trigonometry to find the angle from the North:

Acme Movers charges $210 plus $20 per hour to move household goods across town. Hank's Movers charges $55
per hour. For what lengths of time does it cost less to hire Hank's Movers?
For less than 6 hours, Hank's Movers charge less.
For what lengths of time does it cost less to hire Hank's Movers?Acme movers charge $210 plus $20 per hour, so if they work for x hours they charge:
A(x) = $210 + $20*x
Hank's movers only charge $55 per hour, so here the linear equation is:
H(x) = $55*x
They charge the same amount when:
A(x) = H(x)
$210 + $20*x = $55*x
Now we can solve that to get:
$210 + $20*x = $55*x
$210 = $55*x - $20*x = $35*x
$210/$35 = x = 6
So, for 6 hours, both companies charge the same amount.
For less than 6 hours, Hank's Movers charge less.

Find the equation of a line that passes through (1,12) and is parallel to the graph of y=3x+4 . Write the equation in slope-intercept form.
Answer:
y = 3x + 9
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x + 4 ← is in slope- intercept form
with slope m = 3
• Parallel lines have equal slopes , then
y = 3x + c ← is the partial equation of the parallel line
to find c substitute (1, 12 ) into the partial equation
12 = 3 + c ⇒ c = 12 - 3 = 9
y = 3x + 9 ← equation of parallel line

Monica wants to open a savings account with a deposit of 3,000 monica will not make
Account Y would earn Monica about $62.70 more interest than account X.
Given Monica deposits $3000.
Bank offers two different savings accounts.
Account X pays 2.1% simple annual interest and Account Y pays 2.4% compounded annually, both for 5 years.
For account X, we have:
Principal (P) = $3000
time (t) = 5 years
rate of interest (r) = 2.1%
we need to calculate simple interest:
Simple interest = P×t×r/100
= 3000c5×2.1/100
= $315
simple interest for 5 years is $315
For account Y, we have:
Principal (P) = $3000
time (t) = 5 years
rate of interest (r) = 2.4%
we need to calculate Compound interest:
compound interest = P×(1₊rate)^time ₋ P
= 3000(1₊2.4/100)⁵ ₋ 3000
= 3000(1.024)⁵ ₋ 3000
= 3000(1.12589907) ₋ 3000
= 3377.69 ₋ 3000
= $377.69
The compound interest for 5 years is $377.7
compound interest of account Y ₋ simple interest of account X
= 377.7 ₋ 315
= $62.70
hence the right option is that account Y would earn Monica about $62.70 more interest than account X.

The given function for peanuts is continuous function.
What is defined as the continuous functions?A continuous function, as the name implies, refers to one for whom the graph is continuous without a breaks or jumps.
In other words, if we can create the curve (graph) of a function even without lifting a pencil, we can say that function is continuous.In calculus, a function f(x) is considered to be a continuous function at a point x = a if its curve does not break at that point x = a .For the given expression in the question;
The relation between the cost 'c' and wight 'p' in pounds for the peanuts is given as;
c = 1.5p
As, you can see that the expression is a polynomial having two variables with the highest degree 1.
And, as we know that the every polynomial is a continuous function.
The given function forms a straight line on as for every different real value of p there s single value of c, which varies linearly.

The two shortest sides of a right triangle are 6 and 8 units long, what is the length of the perimeter
The perimeter of the right angled triangle is 24 units.
The perimeter is defined as the sum of all sides of a polygon. To calculate the perimeter of a triangle we add the length of all the 3 sides of the triangle.
The given side lengths are 6 and 8 units.
We know from Pythagorean theorem that for a right angled triangle the sum of the squares of the legs is equal to the square of the hypotenuse of the triangle.
Hypotenuse is the longest side in a right angled triangle.
Therefore the hypotenuse in this triangle is given by:
Hypotenuse² = 6² + 8²
or, hypotenuse = √(36 + 48) units
or, hypotenuse =√100
or, hypotenuse= 10 units
Now perimeter = (6 + 8 + 10) units = 24 units.
Hence the perimeter of the given right angled triangle is 24 units.

Volume of a cylinder given r = radius and h = height is
V = πr²h
Given r = 10 and h = 30
V = π (10)² . (30) ≈ 9424.78 cubic centimeters

if 4 liters of a 15% vinegar solution is mixed with x liters of a 30% vinegar solution, the result is a 25% vinegar solution. How many liters of the 30% vinegar solution were mixed ?
8 liters of 30 percent vinegar solution was mixed.
Percent or percentage is defined as the value for every 100. the simple way to calculate percentage is by dividing the data with the whole data and multiplying it by 100.
4 liters of 15 percent vinegar solution contains:
(15/100)×4 liters of vinegar=0.6 liters
x liters of 30 percent vinegar solution contains:
(30/100)× x liters of vinegar=0.03x liters
Therefore the total vinegar in the 25 percent solution is (0.6+0.3x) liters.
Total volume of the solution is (x+4) liters
(x+4) liters of 25 percent solution contains:
(25/100)×(x+4) liters =(0.25x+1) liters
Now we can equate both values to calculate the value of x from a linear equation:
(0.6+0.3x)=(0.25x+1)
or, 0.05x=1-0.6
or, x= 8 liters
Hence 8 liters or 30 percent solution was mixed.
