Tyler used 114 gallons of paint to paint 47 of a fence. How many gallons will it take to paint the whole fence?
Answer: It will take 199.5 gallons to paint the whole fence.
Step-by-step explanation:
Given: Paint required to paint [tex]\dfrac47[/tex]of fence = 114 gallons
Then , paint required to paint whole fence = [tex]114\div\dfrac47[/tex]
i.e. paint required to paint whole fence = [tex]114\times\dfrac{7}{4}[/tex]
i.e. Paint required to paint whole fence= 199.5 gallons
Hence, it will take 199.5 gallons to paint the whole fence.

Two light houses flash their lights every 20 and 30 seconds respectively. Given that they flash together at 8:00 PM. At what time will they next flash together?
Answer:
They will flash together at;
8:01 PM
Step-by-step explanation:
Here, we want to
calculate the time at which they would both flash together
What we have to do here is to calculate the lowest common multiple of 20
and 30 seconds
Mathematically, we have this as;
60 seconds
60 seconds is the same as 1 minute
So the time they will flash together is 8:01 PM

Explain how to write an equation when given a description of a mathematical problem or real-world scenario.
Answer: In general, look for key words like "is" and "are," or "be." These become the equal sign in the equation.
Other key words to help decide which operation to use:
"And," "plus," and "the total of. . ." are clues for addition.
"Difference" or anything that means distance or amount between two given values is a signal for subtraction.
When Linear dimensions are given and Area is to be found, it will be a multiplication equation. The words "times" and "by" usually mean multiply.
Fractions are often multiplied by some other number.
Ratios are usually division problems.
When a total amount is distributed among some number of people, or you need to find out how many people will get a given share or portion, it is a division equation.
Step-by-step explanation:
It's much easier to explain with specific examples. Here is one.
We set up 15 rows of 6 seats in each row. How many seats are there altogether?
Of is the clue for multiplication Are becomes the equal sign.
15 × 6 = ? how many altogether?
90 = the number of seats.
Answer:
Sample Response: First, the variable needs to be determined. Then identify key words and translate the description. If possible, create a model, such as a diagram or table. Then write the equation using the variable.
Westfalls is 7 miles south of edenville and Concord is 13 mile west of westfalls. What is the distance from edenville to Concord? Round to the nearest tenth of a mile ?
Answer:
[tex]D_x\approx14.8mile[/tex]
Step-by-step explanation:
From the question we are told that
Distance between Edenville and Westfalls [tex]D_1=7[/tex]
Distance between Westfalls and Concord [tex]D_2=13[/tex]
Generally the equation for Pythagoras is mathematically given by
[tex]D_x^2=D_1^2+D_2^2[/tex]
[tex]D_x^2=7^2+13^2[/tex]
[tex]D_x=\sqrt{ 7^2+13^2}[/tex]
[tex]D_x=14.76482306mile[/tex]
The distance b/w Edenville to Concord is
[tex]D_x\approx14.8mile[/tex]
A town's total allocation for firefighters’ wages and benefits in a new budget is $600,000. If wages are calculated at $40,000 per firefighter and benefits at $20,000 per firefighter, write an equation whose solution is the number of firefighters the town can employ if they spend their whole budget. Solve the equation
Answer:
10
Step-by-step explanation:
budget (b) = 600,000
cost per firefighter (c) = 40,000+20,000 = 60,000
total amount of firefighters (t) = b/c
t = 600,000/60,000 = 10
______________________________
N = NumberB = BudgetBPP = Budget Per PersonN = B ÷ BPP= $600,000 ÷ $60,000= 10 Firefighters______________________________

P(NOT red or blue)
Answer:
what's the question? I dont see where your coming from.
Answer question one and show work.
Answer:
x = 28
Step-by-step explanation:
angle 1 and angle 2 are complementary (their sum is 90°)
x + 5 + 2x + 1 = 90 add like terms
3x + 6 = 90 subtract 6 from both sides
3x = 84 divide both sides by 3
x = 28

Stephine puts 30 cubs in a box. The cubes are 1/2 inch on each side. The box holds 2 layers with 15 cubes in each layer.
Answer:
3 3/4 cubic inches,
Step-by-step explanation:
Stephanie puts 30 cubes in a box. The cubes are 1/2 inch on each side. The box holds two layers with 15 cubes in each layer. What is the volume of the box awnsers 5cubic inches, 7 1/2 cubic inches,3 3/4 cubic inches, 15 cubic inches.
✓From the question we are informed that Stephanie puts 30 cubes in a box. The cubes dimension are 0.5 inch on each of the sides.
✓ Since the sides is 0.5inch each, the volume is (0.5×0.5×0.5) The volume of one cube = (0.5 inch)³ = 0.125 inch³
✓ we can calculate the Volume of 30 cubes as
[ 30 cubes in a box × 0.125 inch³]
= 3.75 inch³
✓ 3.75 inch³ can be converted into fraction as (3 3/4) inch³ which is the third Option.

Howie bought 4 binder for $2.14 each, a pack of pencils for $1.25, and a new coat for $19.95. How much money did Howie spend altogether? A. $23.34 B. $27.34 C. $28.66 D.$29.76
Answer:
A. $23.34
Step-by-step explanation:
The computation of the amount of money spend altogether is given below:
= Purchase price of 4 binder + pack of pencils + new coat
= $2.14 + $1.25 + $19.94
= $23.34
We simply added the above three cost so that the total money incurred would be come
Hence, the correct option is A
Samantha wants to hang 3 paintings in her room. The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches. If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?
Answer:
78 inches
Step-by-step explanation:
From the above question, our final answer is in inches, hence:
1 foot = 12 inches
The widths of the paintings are 10+*inches, 3+*feet, and 2 feet, 2),inches.
For painting 2
Converting 3 feet to inches
1 foot = 12 inches
3 feet = x
Cross Multiply
x = 3 × 12 inches = 36 inches
For painting 3
2 feet, 2,inches.
Converting 2 feet to inches
1 foot = 12 inches
2 feet = x
Cross Multiply
x = 2 × 12 inches = 24 inches
Adding up = 24 inches + 2 inches = 26 inches
If she hangs them next to each other with 3 inches between them, what is the total width of the wall space she will need?
This is calculated as:
10 inches + 3 inches + 36 inches + 3 inches + 26 inches
= 78 inches
Therefore, the total width of space she will need = 78 inches
(A journey by bus takes 45 minutes at 60 km per hour. How fast must a car go to do the same
journey in 25 minutes? plzz answerr!!! this is my third time asking this question:(
Answer:
The car must go at 108 km per hour
Step-by-step explanation:
Let us solve the question
∵ A journey by bus takes 45 minutes at 60 km per hour
∴ The speed of the bus = 60 km per hour
∴ The time of the journey = 45 minutes
→ Change the time from minutes to hours
∵ 1 hour = 60 minutes
∴ 45 minutes = 45 ÷ 60 = 0.75 hour
∴ The time of the journey = 0.75 hour
∵ Distance = Speed × Time
→ Substitute the speed by 60 and the time by 0.75
∵ The distance that the bus traveled = 60 × 0.75
∴ The distance that the bus traveled = 45 km
∵ A car goes to do the same journey in 25 minutes
∴ The distance that the car travels = 45 km
∴ The time that the car takes = 25 minutes
→ Divide it by 60 to change it to hours
∵ 25 minutes = 25 ÷ 60 = [tex]\frac{5}{12}[/tex] hour
∴ The time that the car takes = [tex]\frac{5}{12}[/tex] hour
→ Use the rule of the distance above to find the speed of the car
∵ 45 = the car's speed × [tex]\frac{5}{12}[/tex]
→ Divide both sides by [tex]\frac{5}{12}[/tex]
∴ 108 = the car's speed
∴ The car's speed = 108 km per hour
∴ The car must go at 108 km per hour

5x-2x = 7
x+y=7
Answer:
x= 7/3, y= 14/3
Step-by-step explanation:
5x-2x=7
x+y=7
Evaluate 5x-2x=7
5x-2x=3x
3x=7
divide both sides by 3
x=7/3
plug the x value into the second equation
7/3+y=7
subtract 7/3 from both sides
y=7-7/3
evaluate
21/3-7/3=14/3
x= 7/3, y= 14/3
If 5^-x = 25, what is the value of 5^0.5x?
Answer:
