use the formula f=9/5c+32 to convert -20 degrees f
Answer:
c ≈ -29°
Step-by-step explanation:
To convert Fahrenheit to Celsius using the formula, substitute the degrees for Fahrenheit "f", then isolate Celsius "c".
f = [tex]\frac{9}{5}c[/tex] + 32
-20 = [tex]\frac{9}{5}c[/tex] + 32 Substitute "f" for -20
-20 - 32 = [tex]\frac{9}{5}c[/tex] + 32 - 32 Subtract 32 from both sides
-20 - 32 = [tex]\frac{9}{5}c[/tex] +32-32 cancels out to 0. Simplify left side
-52 = [tex]\frac{9}{5}c[/tex]
-52/[tex]\frac{9}{5}[/tex] = [tex]\frac{9}{5}c/\frac{9}{5}[/tex] Divide by 9/5 on both sides
-52/[tex]\frac{9}{5}[/tex] = c
-52[tex]*\frac{5}{9}[/tex] = c When dividing a fraction, flip the fraction and change to multiplication
[tex]\frac{-52*5}{9}[/tex] = c Multiply by combining into the numerator
[tex]\frac{-260}{9}[/tex] = c Use a calculator
c = -28.8888888889°
c ≈ -29° Round to the nearest degrees
Therefore -20°F is about -29°C.
What is the steps for solving 3x-10=84 and tell me what x equals
Answer:
Step-by-step explanation:
you move the -10 to the other side of the equation
3x=84+10
3x=94
x=31 1/3
Answer:
Your goal is to get x by itself
3x-10=84
First you want to add 10 to each side
3x=94 (-10+10=0, 84+10=94)
Last step is divide each side by 3
x= 31 and 1/3 or 94/3
Hope this helps ;)
how many positive integers have a value between the square root of 8 and the square root of 72?
Answer:

Hence, there are 6 such numbers
Will give brainliest The expression to find the perimeter of a rectangle is 2(length + width). What is the perimeter, in units, of a rectangle of length fraction 1 over 3 unit and width fraction 1 over 2 unit? (1 point) fraction 2 over 5 unit fraction 4 over 5 unit fraction 1 and 1 over 3 units fraction 1 and 2 over 3 units
Answer:
Option fraction 1 and 2 over 3 units is correct
Therefore [tex]Perimeter of a rectangle=1\frac{2}{3}[/tex]units
Step-by-step explanation:
Given rectangle of length is fraction 1 over 3 units and width is fraction 1 over 2 units
It can be written as [tex]l=\frac{1}{3}[/tex]units and [tex]w=\frac{1}{2}[/tex]units
To find the perimeter of a rectangle :
Perimeter of a rectangle=2(l+w)
Substitute the values of [tex]l=\frac{1}{3}[/tex]units and [tex]w=\frac{1}{2}[/tex]units in the above formula we get
[tex]Perimeter of a rectangle=2(\frac{1}{3}+\frac{1}{2})[/tex]
[tex]=2(\frac{1(2)+1(3)}{6})[/tex]
[tex]=2(\frac{2+3}{6})[/tex]
[tex]=\frac{5}{3}[/tex]
[tex]=1\frac{2}{3}[/tex]
Therefore [tex]Perimeter of a rectangle=1\frac{2}{3}[/tex]
Therefore option fraction 1 and 2 over 3 units is correct
Answer:
Option fraction 1 and 2 over 3 units

An apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant. The apartment building has 92 total occupants.
2× + 16 = 92
How many double-occupancy apartments are currently rented?
38 double-occupancy apartments are currently rented
Solution:
Given that, apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant
Number of apartments with one occupant = 16
Number of apartments with two occupants = x
The apartment building has 92 total occupants
Therefore, we frame a equation as,
Number of apartments with one occupant + 2 x Number of apartments with two occupants = 92
[tex]16 + 2 \times x = 92[/tex]
16 + 2x = 92
Solve the above equation for "x"
2x = 92 - 16
2x = 76
x = 38
Thus 38 double-occupancy apartments are currently rented
Final answer:
To determine the number of double-occupancy apartments that are currently rented, we solve the equation: 2x + 16 = 92. After simplifying, we find that there are 38 double-occupancy apartments rented.
Explanation:
To determine the number of double-occupancy apartments that are currently rented, we need to solve the equation: 2x + 16 = 92.
First, we subtract 16 from both sides of the equation: 2x = 76.
Next, we divide both sides of the equation by 2 to isolate x: x = 38.
Therefore, there are 38 double-occupancy apartments currently rented.
Which ordered pair is a solution of the equation? y=7x-2
Answer:
(1, 5 )
Step-by-step explanation:
To obtain a solution, substitute any value for x into the equation and solve for y, that is
x = 1 → y = 7(1) - 2 = 7 - 2 = 5 → (1, 5 )
x = - 1 → y = 7(- 1) - 2 = - 7 - 2 = - 9 → (- 1, - 9 ) is also a solution

Is 3 a solution of 2n - 6 = 5n - 15
Answer: Yes
Step-by-step explanation: Here, we want to decide if 3 is a solution for the equation 2n - 6 = 5n - 15. We can do this by simply plugging in 3 for n. If the statement holds true when 3 is plugged in for n, then 3 is a solution.
Plugging in 3 for n, we have 2(3) - 6 = 5(3) - 15.
2(3) is equal to 6 and if we subtract 6 we get 0.
On the right side, 5(3) is equal to 15 and if we subtract 15 we get 0.
0 = 0 is a true statement so yes,
3 is a solution for the equation 2n - 6 = 5n - 15
Is 3/x+4/y=2 linear or non-linear
The given equation is non-linear.
Solution:
Given expression is [tex]\frac{3}{x} +\frac{4}{y} =2[/tex].
To find the equation is linear or non-linear.
Linear equation is a straight line which is in the form ax + by + c = 0.
Otherwise it is non-linear equation.
⇒ [tex]\frac{3}{x} +\frac{4}{y} =2[/tex]
Do cross multiply for the fractions to make the denominators same.
⇒ [tex]\frac{3y}{yx} +\frac{4x}{yx} =2[/tex]
⇒ [tex]\frac{3y+4x}{yx} =2[/tex]
Do cross multiplication.
⇒ [tex]3y+4x=2yx[/tex]
⇒ [tex]4x+3y-2yx=0[/tex]
Here, there is no constant term.
So, the equation is not a straight line.
Hence, the given equation is non-linear.
Expression for the calculation the sum of the product of 4 and 3 and 1 and 1
Answer:
(4 × 3) + (1 × 1)
Step-by-step explanation:
Sum means adding, so you are adding the product of 4 and 3 to the product of 1 and 1.
Product means multiplying, so you are multiplying 4 and 3 together, and since you just want an expression, this is expressed as 4 × 3.
You are also multiplying 1 and 1 together, so that can be expressed by 1 × 1.
Since you are adding these together, you just put a plus sign in between the two terms. That gives you (4 × 3) + (1 × 1).

Answer:
[tex]4\ sea\ urchins[/tex]
Step-by-step explanation:
The correct question is
The number of seahorses is 4 times the number of sea urchins.There are 16 seahorses write and solve and equation to find how many sea urchins are there.
Let
x ----> the number of seahorses
y ----> the number of sea urchins
we know that
The number of seahorses is 4 times the number of sea urchins
so
[tex]x=4y[/tex] -----> equation A
There are 16 seahorses
so
[tex]x=16[/tex] ----> equation B
Solve the system by substitution
substitute equation B in equation A
[tex]16=4y[/tex]
solve for y
divide by 4 both sides
[tex]y=16/4\\y=4\ sea\ urchins[/tex]
Answer:
4.
Step-by-step explanation:
if 4 is the number of Urchins 4*4 is 16 which is how many seahorses there are.

Find the slope of each set of points.
a.) 4, 3 and -3, 4 b.) -2, 0 and (8, -4)
Answer:
1. (4, 3) and (-3, 4) has Slope = -1/7
2.(-2, 0) and (8, -4) has Slope = -2/5
Step-by-step explanation:
If two such points (a,b) and (c,d) are given, then the slope S is given as:
[tex]S = (\frac{d-b}{c-a} )[/tex]
Now here, the given set of points are:
1. (4, 3) and (-3, 4)
Here, the slope S = [tex](\frac{4-3}{-3-4}) = (\frac{1}{-7}) = -(\frac{1}{7})[/tex]
⇒ S = -1/7
1. (-2, 0) and (8, -4)
Here, the slope S = [tex](\frac{-4-0}{8-(-2)}) = (\frac{-4}{10}) = -(\frac{2}{5})[/tex]
⇒ S = -2/5

An equation for the depreciation of a car is given by y = A(1-r), where y = current value of the car, A = original cost, r = rate
of depreciation, and t = time, in years. The current value of a car is $12,282.50. The car originally cost $20,000 and
depreciates at a rate of 15% per year. How old is the car?
Answer:
Step-by-step explanation:
y = A(1 - r)^t......y = value of car after t years.....A = original cost....r = rate of depreciation.....t = time in years
y = 12,282.50
A = 20,000
r = 15% = 0.15
12,282.50 = 20,000(1 - 0.15)^t
12,282.50 / 20,000 = 0.85^t
0.614125 = 0.85^t
log 0.614125 = t * (log(0.85))
t = (log 0.614125) / (log 0.85)
t = 3 <=== 3 years old

To estimate the annual salary for a given hourly pay rate, multiply by 2 and insert “000” at the end.
Sample: $10 per hour is about $20,000 per year.
Explain why this works. Assume the person is working 40 hours a week:
Answer:20000
Step-by-step explanation:
He must have worked for 50 weeks in that year.
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here: hourly rate=10/hr and annual rate is $20000 and he worked 40 hours per week
Thus in a week he earns 40×10=$400
let the person work for x weeks then we have the equation
400×x=20000
x=50 weeks
Hence, He must have worked for 50 weeks in that year.
