Answer:
31/36
Step-by-step explanation:
1/9 + 3/4 = convert the denominators with finding a common multiple of 9 first = 9 x 4 = 36
9 x 4 = 36 and 4 x 9 = 36
?/36
Then convert the numerators with the numbers you bolded
1 x 4 = 4
and 3 x 9 = 27
= 4/36 + 27/36 = 31/36
A square piece of sheet metal is to be used to make a stop sign. each side of the sheet metal is 50cm long. A triangle will be cut off each corner, leaving a regular octagon. which pair of equations can be used to calculate the length of each side of the octagon
Answer:
L = a √( 4 + 2√2)
Step-by-step explanation:
L = a √( 4 + 2√2) is the equation which can be used to calculate the length of each side of the octagon. In the equation i.e. L = a √( 4 + 2√2), in which ''a'' is the length of each side of the octagon. So by putting of ''a'' we get the length of each side of the octagon. The octagon is regular means all of its sides and angles are congruent or similar to each other. Each angle in the octagon has a measure of 135 degrees.
What is the image point of (8, 4) after a translation left 2 units and down 4 units?
Answer:
(6, 0 )
Step-by-step explanation:
A translation to the left means subtract 2 from the x- coordinate
A translation down means subtract 4 from the y- coordinate
Then
(8, 4 ) → (8 - 2, 4 - 4 ) → (6, 0 )

Pls solve I will give the barinliest answer plssss
well we know the line will be equal to 180 degrees so we will have an equation like this
x+100+3x=120
we subtract 100 from 180 to get 80.
180-100=80
however x cannot be 80 bc we still have the 3x.
when you do the math, you will see that 20 times 3 is 60.
20×3=60
going even further we see that 60 plus 20 is 80
60+20=80
so to check our work, lets solve this equation
20+100+3×20=180
20+100=120
3×20=60
120+60=180
so your answer is x=20

a cylindrical jar of jam has a diameter of 6cm and a height of 8 cm. if the jar is 70% full of jam how many cubic centimeters of jam are in the jar? Please answer correctly
Answer: 158.26cm³
Step-by-step explanation:
First, we.need to calculate the volume of the cylinder and this will be:
Volume = πr²h
Volume = 3.14 × 3² × 8
Volume = 3.14 × 9 × 8
Volume = 226.08cm³
Since the jar is 70% full, the volume will be:
= 70% × 226.08cm³
= 0.7 × 226.08cm³
= 158.26cm³
Note:
Radius = Diameter/2 = 6cm/2 = 3cm

En la tienda de electrónica Se vende un televisor en 15480 pesos pero tendrá un descuento del 35% de su precio entonces cuánto costará el televisor y con el descuento
Respuesta:
Monto descontado = 5,418pesos
Nuevo precio de la televisión = 10.062 pesos
Explicación paso a paso:
Costo inicial de televisión = 15,480 pesos
Porcentaje de descuento = 35%
Cantidad descontada = 35% de 15,480
Cantidad descontada = 0.35 * 15,480
Monto descontado = 5,418pesos
Nuevo precio de la televisión = 15.480 - 5.418
Nuevo precio de la televisión = 10.062 pesos

A. 10 cm
B. 15 cm
C. 20 cm
D. 25 cm
The perimeter of the square of side 5 cm is 20 cm
What is the perimeter of square of side 5 cm?The perimeter of a square is calculated with the formula:
Perimeter = 4 * length of side
length of the side = 5 cm
Perimeter = 4 * 5 cm
Perimeter = 20 cm
Therefore, the perimeter of the square is 20 cm

By definition of perimeter, the correct answer is option C. the perimeter of the square is 20 cm.
Definition of perimeterThe perimeter of a two-dimensional figure is the distance around the figure. That is, the perimeter of a flat geometric figure is called the length of its contour.
So, the perimeter is the measurement obtained as a result of the sum of the sides of a flat geometric figure. So to calculate the perimeter of a figure it is necessary to know two basic variables:
The number of sides of the figure.The length of each of those sides.Perimeter of a squareA square is a flat geometric figure that has four equal sides, so the expression to calculate the perimeter of a square is:
Perimeter= 4× length of the sides
This caseIn this case, a square has a side length of 5 cm. So, the perimeter of the square is calculated as:
Perimeter= 4× 5 cm
Solving:
Perimeter= 20 cm
Finally, the correct answer is option C. the perimeter of the square is 20 cm.

which statement best compares the volumes of the two rectangular prisms
Answer:
The volume of prism A is the same as the volume of prism B.
Step-by-step explanation:
Given
See attachment for prisms
Required
Compare the volume of both
First, we calculate the volume of both prisms.
Prism A is a rectangular prism.
So, its volume is:
[tex]V_A = Length * Base * Height[/tex]
Where
[tex]Length \to a[/tex]
[tex]Base \to b[/tex]
[tex]Height \to h[/tex]
So:
[tex]V_A = abh[/tex]
For Prism B, we have:
[tex]Volume = Base\ Area * Height[/tex]
Where
[tex]Base\ Area = Length * Base[/tex]
and
[tex]Length = a[/tex]
[tex]Base = b[/tex]
So:
[tex]Base\ Area = a * b[/tex]
[tex]Base\ Area = a b[/tex]
The volume is then calculated as:
[tex]Volume = Base\ Area * Height[/tex]
[tex]V_B = ab * Height[/tex]
Where
[tex]Height \to h[/tex]
So:
[tex]V_B = ab * h[/tex]
[tex]V_B = abh[/tex]
By comparison:
[tex]V_A = V_B = abh[/tex]

using substitution
x+3y=3
3y-2x=12
Step-by-step explanation:
Given :-
x + 3y = 3 3y - 2x = 12And we need to solve the equation using Substituting method . So on taking the first equation ,
[tex]\rm\implies x + 3y = 3 \\\\\rm\implies x = 3 - 3y [/tex]
Put this value in (ii) :-
[tex]\rm\implies 3y - 2x = 12 \\\\\rm\implies 3y - 2(3-3y)=12\\\\\rm\implies 3y -6-6y = 12 \\\\\rm\implies -3y = 18 \\\\\rm\implies y = -6 [/tex]
Put this Value in (I) :-
[tex]\\\\\rm\implies x = 3-3*-6 \\\\\rm\implies x = 3+18 \\\\\rm\implies x = 21 [/tex]
Hence the Value of x is 21 and y is (-6) .
Answer:
x = -3
y = 2
Step-by-step explanation:
Ok this is a long one but bear with me lol, i promise i will make it easy to understand, performing one step at a time.
So we are given 2 equations right? We can take any of these one equation and isolate any one variable, either x or y, I will take the first equation and isolate x from it cuz it's the easiest way;
=> x + 3y = 3
=> x = -3y + 3 (Let's pretend this is not an equation for x but a "value")
Now that we have the x isolated from first equation, we can substitute x "value" in for the x in second equation. To solve for y;
=> 3y - 2 (-3y + 3) = 12
=> 3y + 6y - 6 = 12
=> 9y - 6 = 12
=> 9y = 12 + 6
=> 9y = 18
=> y = 18/9
=> y = 2
At this point we are almost done with the question! So since we got a real value for one of our variable (which in this case is y-value), we can substitute that in any of the given equation, We can also use the equation where in we isolated "x", so I'll use that cuz it's gonna require less steps, to find the real x-value:
=> The equation we found out up there is: x = -3y + 3
=> Now just simply substitute the y-value we figured in the equation above:
=> x = -3y + 3
=> x = -3(2) + 3
=> x = -6 + 3
=> x = -3
Ayee we did it lol so the final answer would be:
x = -3
y = 2

A boat traveled 448 miles downstream and back. The trip downstream took 14 hours. The trip back took 16 hours. B) boat: 30 mph, current: 2 mph.
How to find the speed of an object?If the object is going linearly, and at a constant speed, then the speed of that object is given by the distance it traveled to the time it took to travel that distance.
If the object traveled D distance in T units time, then that object's speed is
[tex]Speed = S = \dfrac{\: Distance \: traveled}{\: Time \: taken} = \dfrac{D}{T} \: \rm unit \: length/unit \: time[/tex]
A boat traveled 448 miles downstream and back.
The trip downstream took 14 hours. The trip back took 16 hours.
[tex]S = \dfrac{D}{T} \: \rm unit \: length/unit \: time[/tex]
Speed of downstream
448/ 14= 32
Speed of back stream
448 / 16= 28
B = Speed of boat in the water
Y = Speed of current
The system of equation
B + y = 32
B - y = 28
32 + 28 =60
60 / 2 = 30
So,
32 - 30 =2
B = 30
Y = 2

Answer:
3x
Step-by-step explanation:
What you know
This is an equilateral triangle
the x's are all the same
you could write x + x + x = 3x = 16
Multiplying is just adding repeatedly
Answer:16 = 3x
Step-by-step explanation:
Perimeter = Sides surrounding a figure
The triangle has 3 sides, each named "x".
Thus, because the perimeter is equivalent to 16 inches, 3x = 16.
