solve the proportion 20/3 equals something over six piece of correct option 10 23 40 20
Answer:
[4 over x equals 5 over 10]
Solve for x, so you need to isolate/get x by itself in the equation.
Multiply x on both sides
Multiply the inverse of 5/10, which is 10/5, to get rid of the fraction and get x by itself

When Arianna left her house,her cell phone was 45% charged started losing charge at a constant rate. 4 hours after leaving her house, the battery had 15% remaining battery life. Write an equation for B in terms of t representing the charge remaining in Arianna battery as a percentage t hours after Arianna left her house
Answer:
B = 3.75t
Step-by-step explanation:
Given;
initial charge of Arianna's phone = 45%
the charge remaining in Arianna battery = 15%
If after 4hours of leaving her house, the battery had 15% remaining battery life, then the battery is discharging at the rate of ( 15% / 4hours) 3.75% per hour.
Thus, the charge remaining in Arianna's battery after she left her house is given by;
B = 3.75t
where;
t is time in hours
B is the percentage of charge remaining
Consider only the discriminant, b2-4ac, to determine whether one real-number solution, two different real-number solutions, or two
different imaginary-number solutions exist.
4x² - 12x+9=0
A.One real solution
B.Two different imaginary-number solutions
C.Two different real-number solutions
Answer:
A. One real solution
Step-by-step explanation:
The discriminant is used to find the number of real solutions to a quadratic equation.
If the discriminant is greater than 0, there are two real solutions.
If the discriminant is equal to 0, there is one real solution.
If the discriminant is less than 0, there are no real solutions.
All quadratic equations have the format:
ax^2+bx+c
Therefore our values for a, b and c are the following:
a = 4
b = -12
c = 9
Therefore the discriminant is:
(-12)^2-4(4)(9)
144-144 = 0
The discriminant is equal to 0, so there is one real solution (Option A).
Hope this helped!

Step-by-step explanation:
Step 1: Write equation

Step 2: Solve for a
Subtract 9 on both sides: [tex]B-9=\frac{1}{3} qa[/tex]Multiply 3 on both sides: [tex]3(B-9)=qa[/tex]Divide both sides by q: [tex]\frac{3(B-9)}{q} =a[/tex]Rewrite: [tex]a=\frac{3(B-9)}{q}[/tex]
Tory and her friend Terrence ride their bikes to school each day. On one particular day, Tory started out 5 minutes before Terrence. Tory rides at a rate of 880 feet per minute and Terrence rides at a rate of 1.056 feet per minut
How long had Tory been riding when Terrence caught up with her?
Answer:
4:30 minutes im thinking
Step-by-step explanation:
The value is 30 minutes. Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression.
What is meant by expression?Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the expression 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
The expression that give us the distance that Tory has ride after t minutes is:
D = 880t
Because Tory rides at 880 feet per minute.
At the same way, the distance that Terrence has ride after t minutes is equal to:
D = 1056(t - 5)
Because Terrence rides at 1056 feet per minute and he starts out 5 minutes after Tory
Now, we need to find t when both expressions are equal, so we can formulate the following equation:
[tex]880t=1056(t-5)[/tex]
So, solving for t, we get:
[tex]880t=1056t - 1056.5[/tex]
[tex]880t=1056t - 5280[/tex]
[tex]880t=1056t =-5280[/tex]
[tex]-176t=-5280[/tex]
[tex]t=-5280/-176[/tex]
[tex]t= 30[/tex]
Therefore the answer is 30 minutes

TV−→− bisects ∠STU, m∠STV=(14x+8)∘, and m∠UTV=(x+2)∘. Find m∠STU
Answer:
m∠STU is 20°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half the measure of this angle
∵ Ray TV bisects ∠STU
→ That means it divides it into two angles STV and UTV
∴ m∠STV = m∠UTV = [tex]\frac{1}{2}[/tex] m∠STU
∵ m∠STV = ([tex]\frac{1}{4}[/tex]x + 8)°
∴ m∠UTV = (x + 2)°
→ Equate them
∴ x + 2 = [tex]\frac{1}{4}[/tex]x + 8
→ Subtract 2 from both sides
∴ x + 2 - 2 = [tex]\frac{1}{4}[/tex]x + 8 - 2
∴ x = [tex]\frac{1}{4}[/tex]x + 6
→ Subtract [tex]\frac{1}{4}[/tex]x from both sides
∴ x - [tex]\frac{1}{4}[/tex]x = [tex]\frac{1}{4}[/tex]x - [tex]\frac{1}{4}[/tex]x + 6
∴ [tex]\frac{3}{4}[/tex]x = 6
→ Divide both sides by [tex]\frac{3}{4}[/tex] to find x
∴ x = 8
→ Substitute the value of x in the measure of any given angle
∵ m∠UTV = 8 + 2 = 10°
∵ m∠UTV = [tex]\frac{1}{2}[/tex] m∠STU
∴ 10° = [tex]\frac{1}{2}[/tex] m∠STU
→ Multiply both sides by 2
∴ 20° = m∠STU
∴ The measure of angle STU is 20°
20r + 11r + –19r − –4 = –20
Answer:
r=-2
Step-by-step explanation:
First, you need to combine like terms so now you have 12r-(-4)=-20. Then you have to subtract -4 to -20 which equals -24 so now you have 12r=-24. Finally, you divide 12 from both sides and you get r=-2
Answer:
r = -2
Step-by-step explanation:
20r + 11r - 19r + 4 = -20
12r + 4 = -20
subtract 4 from both sides of the equation
12r + 4 - 4 = -20 - 4
12r = -24
divide both sides by 12
12r/12 = -24/12
r = -2

Ralph painted 1/6 of a wall in 2/3 hour. At this rate, how many hours will it take Ralph to paint the whole wall?
Answer:
4 hours
Step-by-step explanation:
Let the size of whole wall be x.
Given that
Ralph painted 1/6 of a wall in 2/3 hours
thus, writing it in mathematical form we have,
time taken to pain 1/6 of x = 2/3 hours
=>time taken to pain x/6 wall = 2/3 hours
since, we have taken size as x so to find time to pain x size of wall ,
we divide both side by 6
=>time taken to pain x/6 * 6 wall = 2/3 *6 hours
=> time taken to pain x wall = 4 hours
Thus, It will take 4 hours to paint whole wall
