Answer:
16.8 cubic metres
Step-by-step explanation:
Given: 1 cubic foot = 6.23 gallons
1 cubic foot = 0.028 cubic metres
Let the conversion into cubic metres be represented by x.
Thus we can say that;
6.23 gallons = 0.028 cubic metres
and
3738 gallons = x cubic metres
So that,
x = [tex]\frac{3738*0.028}{6.23}[/tex]
= 16.8
x = 16.8 cubic metres
The conversion of 3738 gallons into cubic metres is 16.8 cubic metres.

The top walking deck of a ship is 120 ft long. This is only 3/11 of the length of the ship. What is the length of the ship
Answer: 440 ft
Step-by-step explanation:
The top walking deck is 120ft long and yet comprises only 3/11 of the ships total length.
Assuming the total length of the ship is x ft long, the expression would therefore be:
x * 3/11 = 120 ft
The above shows that if x is multiplied by 3/11 it will give a distance of 120ft which is the top walking deck length.
Solving for x:
x * 3/11 = 120
x = 120 ÷ 3/11
x = 120 * 11/3
x = 440 ft
Note: When being divided by a fraction, you can multiply the inverse of the fraction to find the result.
Solve the system by substitution
10x=y
2x+y=-24
Answer: x=-2
Y= -20
Step-by-step explanation
You replace the y in the second equation with 10x. This is because it says 10x=y
2x+10x=12x so you put that
12x=-24
To get x by its self you divide by 12.
-24 divided by 12 is -2.
Now you plug in -2 to either equation as y. I chose the first one because it's easier.
10(-2)=y
-20=y

Irk
James:
Your
Marks
Sarah:
Robert
Answer:
James = 119 points
Sarah = 357 points
Roberts = 51 points
Step-by-step explanation:
Given that :
James = x points
Sarah = 3x points
Roberts = x - 68 points
Each point = 3 pence
All students have a total of £15.81
1 pound = 100 pence
£15.81 pound = 1581 pence
3x + 3(3x) + 3(x - 68) = 1581
3x + 9x + 3x - 204 = 1581
15x - 204 = 1581
15x = 1581 + 204
15x = 1785
x = 1785 / 15
x = 119
Hence,
James = 119 points
Sarah = 119 * 3 = 357 points
Roberts = 119 - 68 = 51 points

Answer:
The exact value of tan A in simplest form is [tex]tan (A) = \dfrac{9}{40}[/tex]
Step-by-step explanation:
The parameters of the given right triangle are;
The length of the hypotenuse side = 41
The length of the vertical leg of the right triangle = 9
The length of the opposite leg of the right triangle = 40
By trigonometric rule, we have;
[tex]tan (A) = \dfrac{Opposite \ leg \ length \ to \ angle \ A}{Adjacent \ leg \ length \ to \ angle \ A }[/tex]
Therefore, we have;
[tex]tan (A) = \dfrac{9}{40} = 0.225[/tex]

The polynomial x^2-18x+81 represents the area(in square feet) of a square courtyard. Write an expression for the perimeter of the courtyard.
Answer:
4x - 36 feet
Step-by-step explanation:
The area A of a square whose sides are s units is given as
A = s * s
Given that the area A = x^2-18x+81, factorizing
A = x^2-9x-9x+81
A= x(x-9)-9(x-9)
A = (x-9)(x-9)
A = (x-9)^2
This means that the size of each side of the square courtyard is x-9 feet long
Recall that the perimeter P of a square whose side is s long is given as
P = 4s hence since the side of the courtyard is x - 9 feet, the perimeter of the courtyard
P = 4(x-9)
= 4x - 36 feet

multiplication equation can you use
to check your answer?
The number of 1/8s which are in 25 as required to be determined is; 200.
What is the number of 1/8s in 25?It follows from the task content that the number of 1/8s in 25 as required in the task content is to be determined.
It follows from arithmetic principles that the number of 1/8s in 25 can be determined by evaluating; 25 ÷ 1/8
= (25 × 8) / 1
= 200.
Therefore, the number of 1/8s in 25 is; 200.
Also, if the number of 1/8s in 25 is to be determined; the multiplication equation to check the answer is; 1/8 × 200 = 25....which holds true.

What is the preimage of D' (4, -3)?
Answer:
(12,-7)
Step-by-step explanation:
The required ordered pair of the pre-image of D'(4, -3) is D(12, -7).

Answer:
61
Step-by-step explanation:
Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.
Simplifying, we get;
9x - 31 + 7x - 2 + 4x + 33 = 180
20x = 180
x = 9.
So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61
Identify the slope AND y-intercept of the equation below.
y=4x−7
Answer:
slope = 4/=7
y int = -7
Step-by-step explanation:
slope = rise/run
slope = 4/-7
y int:
y = 4(0)-7
y= 0-7
y int = -7
The slope and y-intercept of the equation are 4 and -7 respectively.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
The given equation of a line is y=4x-7.
By comparing y=4x-7 with y=mx+c, we get
m=slope = 4 and c=y-intercept=-7
Therefore, the slope and y-intercept of the equation are 4 and -7 respectively.

At 9AM a train traveling 60 miles per hour leaves Los Angeles for San Francisco, a distance of 400 miles. At noon a car traveling at an average speed of 40 miles per hour leaves San Francisco for Los Angeles. At what time will the two vehicles pass each other?
ANSWER PLS
Answer is in the picture:
At 2:02 PM the two vehicles pass each other.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Given thta,
Los Angeles to San Francisco:
rate = 60 mph ; distance = x miles ; time = d/r = x/60 hrs
San Francisco to Los Angeles:
rate = 40 mph ; distance = 400-x ; time = d/r = (400-x)/40 hrs
So, equation is
x/60 = (400-x)/40 + 3
x/60 = (400-x)+120/40
40x = 60[(400-x)+120]
40x=24000-60x+7200
100x=31200
x=312 miles
Now, time = 312/60
= 5.2 hours
Clock time = 9+5.2
= 14.2 hours
= 2:02 PM
Therefore, at 2:02 PM the two vehicles pass each other.
