Nardia plots points showing equivalent ratios on the coordinate plane below. Mc018-1. Jpg Which ordered pair would represent a ratio that is equivalent to those shown? (6, 12) (9, 6) (8, 12) (12, 8).
Answers
The ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)
Ratio and proportionsFrom the given diagram, we can create two coordinate points which are (2, 3) and (4, 6)
We need to determine the ordered pair would represent a ratio that is equivalent.
Multiplying the coordinate by a scale factor of 4 will give
A(2, 3) = A'(4(2), 4(3)) = (8, 12)
Hence the ordered pair that would represent a ratio that is equivalent to those shown is (8, 12)

Step-by-step explanation:
An ambulance travels at 40 mph and can follow a 20-mile route making no stops to get to the hospital. A helicopter travels at one mile per minute, and the air route is 15 miles to get to the same hospital. However, the helicopter takes three minutes for takeoff and three minutes for landing. How many fewer minutes does it take for the helicopter to complete its trip (takeoff, flight and landing) than for the ambulance to complete its trip
Answers
Answer:
9
Step-by-step explanation:
The time required by the ambulance is ...
time = distance/speed
time = (20 mi)/(40 mi/h) = 1/2 h = 30 minutes
The time required by the helicopter is ...
trip time = takeoff time + route time + landing time
= (3 min) + (15 mi)/(1 mi/min) +(3 min) = (3 + 15 + 3) min = 21 min
The difference in times is ...
(30 min) -(21 min) = 9 min
The helicopter takes 9 fewer minutes for the trip.

what does cos mean in math?
Answers
Answer:
cosine
Step-by-step explanation:
"cos" is an abbreviation for "cosine," the name of the trig function that relates the hypotenuse of a right triangle to the length of the side adjacent to the angle of interest.
For an angle measured in radians, the value of the cosine of the angle is defined by the power series shown in the second attachment. Any scientific or graphing calculator can evaluate this function. Generally, best accuracy from a calculator is obtained for angles between -2π and +2π radians, or ±360°. Calculators generally can use angles expressed in degrees or radians, so care is required to make sure the calculator mode matches the units you are using. (Spreadsheet functions typically require angles to be in radians.)
The cosine function is periodic, with a period of 2π radians. Its value for x=0 is 1. A graph of the cosine and sine (abbreviated "sin") functions is shown in the third attachment. Each is a horizontal shift of the other.
__
The three primary trig functions relate pairs of sides of a right triangle to one of the acute angles. The relationship between trig functions and sides is summarized in the mnemonic SOH CAH TOA. The first attachment shows what that means.

tan 47° = a / 570
cross multiply
a = 570 tan 47°

Solve each system by substitution
2x+y=20
6x-5y=12
what is (x,y)?
Answers
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:(7,6)
Equation Form: x=7, y=6
2x+y=20
6x-5y=12
First get y by its self
2x+y=20
y= -2x+20
Now plug into second equation for y
6x-5(-2x+20)=12
6x+10x-100
16x-100=12
16x=112
x=7
now plug in x value into first equation and solve for y
2(7)+y=20
14+y=20
y= 6
Now check by plugging x and y values back into equation
2(7)+6=20
6(7)-5(6)=12
They both work so x=7 and y =6
Which of these numbers is irrational?
A. 12
B. -4.2
C. 1/42
D. 4.2
Answers
Answer:
A: 12
Step-by-step explanation:
An Irrational Number is a real number that cannot be written as a simple fraction. (Irrational means not rational).
Therefore, we can immediately discount C as 1/42 is a rational number by inspection.
[tex]4.2=\frac{4.2}{1} =\frac{4.2}{1} \times \frac{10}{10} =\frac{42}{10}=\frac{21}{5}[/tex] so similarly -4.2 = -21/5
So as B and D can also be written as rationals, they are not irrational.
Therefore, A is irrational.

In large cities, people often take taxis to get from one place to another. If a 36 mile costs $25.20, what is the cost per mile? How much would a 47 mile ride cost? I need two answers
Answers
Answer:
$0.70 per mile
47 miles = $32.90
Step-by-step explanation:
Set up a proportion
36 miles / $25.20 = 1 mile / $x
Cross multiply
36x = 25.20
Divide both sides by 36
x = 0.7
0.7 × 47 to find the cost for 47 miles
0.7 × 47 = 32.90
