Answer:
a. -10.
Step-by-step explanation:
The formula is 5/9 * (F-32).
So 14-32 = -18
5/9 * -18 = -10
(14°F − 32) × 5/9 = -10°C

ASA
Can't Determine
ASA
Angle-Side-Angle
AAS is the same but the order in different.
SAS is a no because there are no two S.
Can't determine bah! You can determine.
PLEASE BRAINLIEST
Answer:
The markings are different.
SAS and ASA would work, as you can count the sides and angles respectively, however, the markings are different, so I am not sure.
Actually I was wrong. Please give the other person credit.
A passenger train travels between two
cities at a constant speed. After 6 hours,
it has traveled 450 miles. After 9 hours, it
has traveled 675 miles. Which equation
shows the relationship between the
distance d in miles and the time t in hours?
Answer:
The train travels 75 mph.
Step-by-step explanation:
Hope this helps!
Answer:
(75, 1)
Step-by-step explanation:
One way we can figure out how fast the train goes, is bylooking at what we have. We know that the train travels 450 miles in 6 hours. When we divide, we get 75. So, we know that the train is going at 75 miles per hour. We can check our work by looking at the second relationship on there. When 675 is divided by 9, we get 75. So for every hour, the train travels 75 miles.
I hope that this helps you out :)
How pure is 16-karat gold?
Answer:
here

Please helpppp :< here is 25 points
Answer:
function b
Step-by-step explanation:
When its asking for which function has a greater rate of change its asking for which slope has a greater value
the slope is calculated by change in y over change in x
for function a, as y goes up 2 x goes up 1
so the slope ( rate of change) is 2/1
for function b is y goes up 3 x goes up 1
so the slope (rate of change) is 3/1
3/1 is greater than 2/1 so function b has a greater rate of change

x = -4y
3x + 2y = 20
Answer:
(x, y) = (8, -2)
Step-by-step explanation:
Substitute:
3(-4y) + 2y = 20
-12y + 2y = 20
-10y = 20
y = -2
x = -4(-2) = 8
The Bigtown football team outscored its opponents 5:2 last season. If their opponents scored 38 points, how many points did Big Town score? (Hint: Bigtown is first in the ratio)
Answer:
95 points
Step-by-step explanation:
Let P = Big Town's points
5/2 = P/38
2P = 190
P = 95 points

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 1997 his card was worth $4.51 The value has increased by $1.02 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2008?
Step-by-step explanation:
When he retired in 1997 his card was worth $4.51 The value has increased by $1.02 each year since then.
Express the relationship relating the value of the card y in dollars and the number of years x
y = $1.02 x + $4.51
Is the relationship between x and y proportional?
Yes. This is because as x increases, the value of y also increases.
What was the value of the card in 2008?
Number of years from 1997 to 2008 = x = 11
y = $1.02 x + $4.51
y = $1.02 (11) + $4.51
y = $ 11.22 + $4.51
y = $ 15.73

The radius of Circle A is 6 mm. The radius of Circle B is 4 mm greater than the radius of Circle A. The radius of Circle C is 2 mm greater than the radius of Circle B. The radius of Circle D is 3 mm less than the radius of Circle C. What is the area of each circle? How many times greater than the area of Circle A is the area of Circle D
Answer:
Area of circle A =113.14 mm²
Area of circle b = 314.29 mm²
Area of circle C = 452.57 mm²
Area of circle A = 254.57 mm²
2.25 times
Step-by-step explanation:
Area of a circle = nr²
where n = 22/7
r = radius
Circle A's radius = 6mm
Circle B's radius = 6mm + 4mm = 10mm
Circle C's radius = 10mm + 2mm = 12mm
Circle D's radius = 12mm - 3mm = 9mm
Area of circle A = (22/7) x 6² = 113.14 mm²
Area of circle b = (22/7) x 10² = 314.29 mm²
Area of circle C = (22/7) x 12² = 452.57 mm²
Area of circle A = (22/7) x 9² = 254.57 mm²
Number of times the area of circle D is greater than that circle A = Area of circle D / Area of circle A
254.57 mm² / 113.14 mm² = 2.25 times
