The day's high temperature in Phoenix, Arizona was recorded as 104°F. Use the formula C= 5F- -32) to write 104°F as degrees Celsius.
The day's high temperature written as degrees Celsius is lºc.
(Answer quickly)
Answer:
40°C
Step-by-step explanation:
Plug in 104° for F. This makes the equation [tex]\frac{5}{9}(104-32)=C[/tex].
Now, simplify.
[tex]104-32=72\\\frac{5}{9} (72)=40\\C=40[/tex]

Find the discriminate, number of roots and solve the quadratic equation using the quadratic formula -my answers are pribably wrong
Answers:
discriminant = dnumber of roots = esolutions = g=================================================
Explanation:
Let's compute the discriminant. Here we have a = 1, b = 1, c = -2
d = b^2 - 4ac
d = 1^2 - 4(1)(-2)
d = 9
The fact that d > 0 tells us we have two different real number solutions.
------------------------
We can use the quadratic formula to solve, or we can factor. I'll use the factor method.
x^2 + x - 2 = 0
(x - 1)(x + 2) = 0
x-1 = 0 or x+2 = 0
x = 1 or x = -2
The two solutions are -2 and 1
Stephanie is painting her room wich is 14' long by 9' wide and each wall is 10' tall. How many square feet of paint will she use? help.
Answer:
460 sq ft
Step-by-step explanation:
Assuming the room is a perfect rectangle and not accounting for doors and windows:
14 ft x 10 ft = 140 sq ft X 2 = 280 sq ft
9 ft x 10 ft = 90 sq ft x 2 = 180 sq ft
280 sq ft + 180 sq ft = 460 sq ft

Ann - a, Josh - j, Claire - c
a = j + 7j = 2ca + j + c = 157Substitute a and j into last equation and solve for c:
(j + 7) + 2c + c = 1572c + 7 + 3c = 1575c = 150c = 30Find a and j:
a = 30 + 7 = 37j = *30 = 60Solve for b
-3(6b + 4) = 2(-5b+10)
b=
Answer:
b = -4
Step-by-step explanation:
-3(6b + 4) = 2(-5b + 10)
-18b - 12 = -10b + 20
(-18b + 10b) - 12 = (-10b + 10b) + 20
-8b - 12 = 20
-8b (- 12 + 12) = 20 + 12
-8b = 32
-8b/-8 = 32/-8
b = -4

find the mean of 31.6, 34.5, 29.8, 12,1
Answer:
27
Step-by-step explanation:
To figure out the mean of a group of numbers, one must add the numbers together and divide by the number of terms.
31.6 + 34.5 + 29.8 + 12.1 = 108
There are four terms in the group of numbers.
108 / 4 = 27
Therefore, the mean is 27.

Answer:
1. 7
2. 13
Step-by-step explanation:
1. x = 2 and y = 3
y^2 - x
= 3^2 - 2
= 9 - 2
= 7
2. x = 5 and z = 4
z + x + z
= 4 + 5 + 4
= 9 + 4

plzz someones help me plz I will mark brainlest diameter is 1 3/4
Answer:
The area of the circle is 2.41 in^2
Step-by-step explanation:
You are given the diameter, 1 3/4. This is a mixed fraction, so let's convert that into decimal.
1 3/4 = 7/4
7/4 = 1.74
Now, let's use the area of circle formula.
A = 1/4πd^2
A = 1/4 * π * 1.75^2
A ≈ 2.40528
Let's round the area to the nearest hundredth.
2.40528 = 2.41
A number to be a rational number that is not an integer but a while number
Answer:
So coming back to the question; No, there is no rational number that is not an integer but is a whole number. The number is called as a rational number if it can be expressed as p/q where p & q are integers & q is not 0. All negative integers are rational numbers but those are not whole numbers.Jan 1, 2020

Nick and Monica are paid $41.25 for their work. Nick worked 2.5 hours, and Monica worked 3 hours. They split the money according to the amount of time each of them worked.
Nick and Monica are paid $(Blank) for each hour worked. Nick's share of the money is $(Blank)
Answer:
BRIANLIEST PLZ
N = 18.75
M = 22.5
Step-by-step explanation:
Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.
T = t1 + t2 = 2.5 + 3 = 5.5
r1 =2.5/5.5
r2 = 3/5.5
Nick = r1 * 41.25 = 18.75
Monica = r2 * 41.25 = 22.5
