Answer:
A. y+4=f(x)
Step-by-step explanation:
if you were to make this a y= equation then you would have to move the 4 to the other side by subtracting 4 from both sides therefore making the value of f(x) - 4

Tanya buys 12 water bottles. Of these bottles, 5 hold 300 milliliters each and 7 hold 1.5 liters each. Part A How much water, in milliliters, does Tanya buy? Enter your answer in the box. Part B How much water, in liters, does Tanya buy? Enter your answer in the box.
Answer:
A- 12,000ml
B- 12l
Step-by-step explanation:
To find milliliters:
1.5l = 1500ml
300(5) + 1500(7) = (1500 + 10500 =) 12,000ml
To find liters:
300 ml = 0.3l
0.3(5) + 1.5(7) = (1.5 + 10.5 =) 12L

thank you ❤❤
Answer:
Step-by-step explanation:
z= y( z-y)/x
z = yz - y^2 /x
zx = yz -y^2
y^2 = yz - zx
y^2 = ( y- x)z
therefore z = y^2/(y-x)

Answer:
2122.64 in^2
Step-by-step explanation:
Use the formula for the area of a circle: A=πr^2
The radius will be half the width of the cloth so 52÷2=26
26^2=676
Multiply by π given as 3.14

What is the ratio of two quantities?Suppose that we've got two quantities with measurements as 'a' and 'b'
Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]
We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).
Suppose that we've got a = 6, and b= 4, then:
[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]
Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.
Let we suppose that:
The radius of circle A = C unitsThe radius of circle B = s units.Then we get:
Circumference of circle A = [tex]2\pi r \: \rm units[/tex]Circumference of circle B = [tex]2\pi s \: \rm units[/tex]As per the given information:
The circumference of a circle B is 80% of the circumference of circle A, or:
[tex]2\pi s \: \rm units[/tex] = 80% of [tex]2\pi r \: \rm units[/tex]
or:
[tex]2\pi s = \dfrac{2\pi r}{100} \times 80\\\\s = 0.8r \: \rm units[/tex]
Also, we have:
Area of circle A = [tex]\pi r^2 \: \rm units[/tex]Area of circle B = [tex]\pi s^2 \: \rm units[/tex]The rato of the area of the circle A to the area of the circle B is:
[tex]Area(A): Area(B) = \dfrac{\pi r^2}{\pi s^2} = \left( \dfrac{r}{s}\right)^2[/tex]
since we've got [tex]s= 0.8r[/tex], therefore,
[tex]Area(A): Area(B)= \left( \dfrac{r}{s}\right)^2 = \left(\dfrac{r}{0.8r}\right)^2 = \dfrac{100}{64} \\\\Area(A): Area(B)=\dfrac{100}{64} = 100:64[/tex]
Thus, the ratio of the area of circle A to the area of circle B for the considered circle A and B is 100:64

100 POINTS WILL MARK BRAINLIEST x^2 − 8x + 13 = 0 Which of the following is the first correct step to write the above equation in the form (x − p)^2 = q, where p and q are integers? Subtract 5 from both sides of the equation Add 3 to both sides of the equation Add 5 to both sides of the equation Subtract 3 from both sides of the equation
Answer:
We will add 3 to each side of the equation
Step-by-step explanation:
x^2 − 8x + 13 = 0
We want to complete the square
We will subtract 13 from each side of the equation
x^2 -8x +13 -13 = 0 -13
x^2 -8x = -13
Then take the coefficient of x
-8
Divide by 2
-8/2 = -4
Square it
(-4)^2 = 16
Add this to each side
x^2 -8x +16 = -13+16
( x-4) ^2 = 3
The sum of subtracting 13 and adding 16 is adding 3
Answer:
It is Subtract 3 from both sides of the equation

Find the arc length of AB. Round answer to nearest tenth.
Answer:
9.8 inches
Step-by-step explanation:
Set up a proportion:
central angle / 360 = arc length / circumference
[tex]\frac{80}{360}[/tex] = [tex]\frac{x}{14\pi }[/tex]
360 divided by 14pi is about 8.2, so divide 80 by 8.2 to find x.
x = 9.8 in
Answer:
9.8 inches
Step-by-step explanation:
The formula for arc length is (θ/360)2πr
This is where θ represents the measure of the central angle in degrees,
and r represents the radius of the circle.
This said, we can plug our values in.
(80/360)2π7
Simplify.

One vertex of a triangle is located at (0,5) on a coordinate
grid. After a transformation, the vertex is located at (5,0).
Which transformations could have taken place? Select
two options.
Ro, 90°
Ro, 180°
Ro, 270°
U
Ro -90°
Ro -180°
Answer: Ro, 270° and Ro -90°
Step-by-step explanation: If the vertex is at 5 on the y-axis at (0,5) and the transformation has moved the vertex to (5,0) it is now at +5 on the x-axis. This is a rotation around the origin, Rotation notation Ro.
This is fairly easy to visualize: like the hand of an analog clock moving from 12 o'clock to 3 o'clock.
In geometry, rotations are given in degrees, moving counter-clockwise. There are 360° in a circle.
Moving 3/4 of the way around the circle counterclockwise.
Multiply(3/4)(360) = 270. This is a positive rotation, counter-clockwise
Clockwise, it is 1/4 of the circle, so Multiply (1/4)(360)= 90 But remember to add the negative sign because clockwise is considered a negative rotation.
Ro, -90°
The transformations that could have taken place are Ro, 270° and Ro -90°
How to determine the transformationsThe vertex of the triangle is given as: (0,5)
After transformation, the vertex of the image is given as: (5,0)
The transformation follows the rule:
[tex](x,y) \to (y,x)[/tex]
The above rule represent:
90 degrees counterclockwise rotation270 degrees clockwise rotationHence, the true statements are Ro, 270° and Ro -90°

Al mediodía me he comido la mitad de una tortilla de patatas. A la hora de la merienda, Ana ha tomado un tercio de la tortilla original, y para cenar, Luis se ha tomado tres cuartas partes de lo que quedaba. ¿Qué fracción de la tortilla queda al final del día?
Answer:
[tex]\frac{1}{24}[/tex]
Step-by-step explanation:
La mitad es 1/2 y un tercio es 1/3. Como una persona se comió 1/2 y Ana 1/3, puedes determinar lo que se comieron sumando:
[tex]\frac{1}{2}[/tex]+[tex]\frac{1}{3}[/tex]=[tex]\frac{3+2}{6}[/tex]=[tex]\frac{5}{6}[/tex]
Como se comieron 5/6, puedes restar esto de 6/6 para determinar cuanto quedó de la tortilla:
[tex]\frac{6}{6}-\frac{5}{6}= \frac{6-5}{6} =\frac{1}{6}[/tex]
De acuerdo a esto, quedó 1/6 de la tortilla. Luis tomó tres cuartas partes de lo que quedaba, lo que significa que quedó 1/4 de 1/6. Para encontrar la fracción de la tortilla que quedó puedes dividir 1/6 entre cuatro para saber a cuanto corresponde una cuarta parte de 1/6:
[tex]\frac{1}{6}[/tex]÷4= [tex]\frac{1/6}{4}= \frac{1}{6*4}=\frac{1}{24}[/tex]
De acuerdo a esto, la fracción de la tortilla que quedó al final del día es [tex]\frac{1}{24}[/tex].
