A temperature C, in degrees Celsius, is the same as a temperature of
9
5
C+32, in degrees Fahrenheit. The hottest temperature ever recorded in Puerto Rico was 40 degrees Celsius.
Based on the information given, the temperature when converted to Fahrenheit will be 104° Fahrenheit.
Solving the temperature.It should be noted that when converting to Fahrenheit from Celcius, one has to multiply by 1.8 and then add to 32.
In this case, the temperature given in Celcius is 40°. Therefore, the Fahrenheit will be;
= (1.8 × 40) + 32.
= 72 + 32
= 104°F

Mr. Akika has 49 21 cent and 31 cent stamps all told. The stamps are worth $13.39. how many of each kind of stamps does he have?
Mr Akika has 18 21-cent stamp and 31 31-cent stamp.
He has 49 21-cent and 31-cent stamps all told.
let
x = number of 21 cent stamp
y = number of 31 cent stamp
Therefore,
Total number of stamp:x + y = 49Total cost of stamp:21x + 31y = 1339Therefore,
x + y = 49
21x + 31y = 1339
21x + 21y = 1029
10y = 310
y = 310 / 10
y = 31
Therefore,
x = 49 - 31
x = 18
Therefore, Mr Akika has 18 21-cent stamp and 31 31-cent stamp.

There are 3 white balls, 7 red balls, and 5 green balls in a container. A ball is chosen at random. What is the probability of choosing a green ball , keeping it, and then choosing a red ball?
Answer:
(p green) 1/3
(p red) = 1/2
Step-by-step explanation:
Add the number of balls together to get the total.
3 + 7 + 5 = 15
Find the probability of choosing green.
(p green) = 5/15
reduce by 5
(p green) 1/3
Since you kept the green ball, there are now a total of 14 balls.
Find the probability of choosing red.
(p red) = 7/14
reduce by 7
(p red) = 1/2

Step-by-step explanation:
g(f(x)) = -3(x²-2x+13) + 8
g(f(x)) = -3x²+6x-39+8
g(f(x)) = -3x²+6x-31
g(f(1)) = -3(1²)+6(1)-31 ⇒ -3 + 6 + (-31) ⇒ 3+(-31) ⇒ -28

Can someone please help with 2 or 3 please !!
Step-by-step explanation:
2.
if parallel, the ratio of the line segments AD/DB must be the same as AE/AC.
4/2 = 2
but
9/5 is not 2 (10/5 would be 2).
so, they are not parallel.
3.
the area of a right-angled triangle is half the area of a rectangle with the same side lengths.
so, the area of ABC is
4×5/2 = 20/2 = 10
since D and E are midpoints, they are splitting the sides in half.
so, AD is only half as long as AC. the same for CE and CB.
so, the area of DEC is
2×2.5/2 = 5/2 = 2.5
the scale factor of the sides does apply to the area in a way, but not 1:1.
as the area is calculated by multiplying 2 sides, the scale factor is entering the calculation for each side and therefore twice. that means the scale factor is multiplied by itself.
so, the scale factor of the areas is in fact the square of the scale factor of the side lengths.
therefore, in our example here, the scale factor of the side lengths is 1/2. and the scale factor of the areas is (1/2)² = 1/4.
and indeed, 10× 1/4 = 10/4 = 2.5
A private jet can fly 2145 miles in three hours with a tailwind, but only 1809 miles in three hours with a headwind.
The speed of the private jet is 659 miles per hour.
SpeedSpeed is the ratio of distance travelled to total time taken. It is given by:
Speed = distance / time
Let a represent the speed of the jet and b represent the speed of the wind. The private jet can fly 2145 miles in three hours with a tailwind, hence:
(a + b)3 = 2145
a + b = 715 (1)
It can travel 1809 miles in three hours with a headwind, hence:
(a - b)3 = 1809
a - b = 603 (2)
From equation 1 and 2:
a = 659, b = 56
The speed of the private jet is 659 miles per hour.

What is the unit rate?
Enter your answer, rounded to the nearest cent, in the box.
This represents $0.19 per ounce which is the same as 19 cents per ounce.
=============================================================
Explanation:
To find the unit rate, we divide the cost over the number of ounces
(3.79 dollars)/(19.5 ounces) = 0.19435897 dollars per ounce approximately
Round this to the nearest cent, i.e. hundredth, to get 0.19 dollars per ounce. This is the same as saying "19 cents per ounce".
