6.5 x 9  = 58.5

she used half a jar, so that means half of 6.5, which is 3.25. Add 58.5 and 3.25, and you get 61.75.

Also 6.5 x 9.5 = 61.75

Answer:

The rule of dilation by a scale factor 4 is:

(x, y)  →  (4x, 4y)

P(4, 2)  →  (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Step-by-step explanation:

Given the point

As the image coordinates of (4, 2) are (16, 8) after the scale factor, we need to determine what could be the scale factor.

It is clear that the coordinates of the image P'(16, 8) are 4 times the coordinates of the original point P(4, 2), which means the point P(4, 2) is dilated by a scale factor of 4.

Thus, the rule of dilation by a scale factor 4 is:

(x, y)  →  (4x, 4y)

P(4, 2)  →  (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Answer:

-2

Step-by-step explanation:

12 is the larger number so if you take a bigger number and subtract it from a smaller number you get negative

The value of the difference 10 - 12 is -2.

The difference between 10 and 12 is calculated by subtracting the smaller number from the larger number.

We have to find difference of 10 - 12.

When we subtract 12 from 10, we get a result of -2.

The negative sign indicates that 12 is greater than 10, and the absolute value of 2 represents the numerical difference between the two numbers.

So, the difference between 10 and 12 is -2.

Angel receives 300 votes which is 60% of total votes.

Therefore we can determine 60% = 300

The next thing to do would be to determine 1% and we can do this by dividing both sides by 60:

60% = 300

1% = 5

Then multiply both sides by 100 to determine 100% of total votes (total amount of students who voted):

1% = 5

100% = 500

Therefore 500 students voted in the election.

Answer:

500 students

Step-by-step explanation:

300=60%

300x2=600

(turning the 300 into 600 helps it make sense)

600/3=200

200x5= 1000

1000/2=500

Step-by-step explanation:

34x+85=3(13x+7)

Step 1: Simplify both sides of the equation.

34x+85=3(13x+7)

34x+85=(3)(13x)+(3)(7)(Distribute)

34x+85=39x+21

Step 2: Subtract 39x from both sides.

34x+85−39x=39x+21−39x

−5x+85=21

Step 3: Subtract 85 from both sides.

−5x+85−85=21−85

−5x=−64

Step 4: Divide both sides by -5.

−5x/−5=−64/−5

x=64/5

Given that :

Fuel tank of cruise ship hold 28,665 barrels

Capacity of fuel tanker = 5312 barrels

Can 5 fuel tankers fuel fill the cruise ship's tank?

5 * capacity of fuel tanker

5 * 5312 = 26,560 barrels

No because 28665 > 26560

Step-by-step explanation:

surface area = 2 (LW + LH + WH)

a)

where L = length = 8

          W = width = 2

           H = height = 2

plugin values into the formula:

surface area = 2 (8*2 + 8*2 + 2*2)

                     = 2 (16 + 16 + 4)

                     = 72

---

b)

where L = length = 2

          W = width = 3

           H = height = 9

plugin values into the formula:

surface area = 2 (2*3 + 2*9 + 3*9)

                     = 2 (6 + 18 + 27)

                     = 102

---

c)

surface area = 2(area of rectangular side) + 2(area of triangular side) + base area

plugin values into the formula:

surface area = 2 (2*7)  + 2( 1/2 * 7 * 6.1)  + (2*7)

                     = 28 + 42.7 + 14

                     = 84.7

Answer:

The simplest form of [tex]\frac{14a^2}{24a}[/tex]  is [tex]\mathbf{\frac{7a}{12}}[/tex]

Step-by-step explanation:

We need to write [tex]\frac{14a^2}{24a}[/tex] in simplest form.

We know the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex]

Applying the rule:

[tex]\frac{14a^2}{24a} \\=\frac{14a^{2-1}}{24}\\Since \ 14 \ and \ 24 \ are \ divisible\ by \ 2 \\=\frac{7a^1}{12} \\=\frac{7a}{12}[/tex]

The simplest form of [tex]\frac{14a^2}{24a}[/tex]  is [tex]\mathbf{\frac{7a}{12}}[/tex]

Answer:

Answer:

[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} } [/tex]

Step-by-step explanation:

First thing is to multiply. We don't need to bother with the root for now.

[tex] \sqrt{15 {x}^{2} {y}^{11} {z}^{4} } \times \sqrt{5xy {z}^{7} } = \\ \sqrt{75 {x}^{3} {y}^{12} {z}^{11} } [/tex]

All I did was multiply the numbers and added the exponents for the variables.

Now all we have to do is divide the exponents in half for the variables, nothing is needed additionally for the 75.

[tex]75 {x}^{ \frac{3}{2} } {y}^{6} {z}^{ \frac{11}{2} }[/tex]

There you go, just a few steps and you have your answer.

You can simplify further by moving the answer for the root infront of the square root so it isn't as sloppy. This would make the simplest for to be

Answer:

La edad del padre es 40 años, la edad del hijo menor es 2 años y la del hijo mayor es 6 años.

Step-by-step explanation:

Un sistema de ecuaciones lineales es un conjunto de ecuaciones lineales que tienen más de una incógnita. Las incógnitas aparecen en varias de las ecuaciones, pero no necesariamente en todas, y se relacionan mediante las ecuaciones. En otras palabras, un sistema de ecuaciones es un conjunto de dos o más ecuaciones con varias incógnitas en la que desea encontrar una solución común, es decir, encontrar el valor de cada incógnita para que se cumplan todas las ecuaciones del sistema.

En este caso debes resolver una sistema de ecuaciones, para lo cual debes en primer lugar definir las variables a utilizar:

Entonces, siendo:

Se puede expresar simbólicamente como:

que será el sistema de ecuaciones a resolver.

Para resolver se puede usar el método de sustitución, que consiste en despejar o aislar una de las incógnitas (por ejemplo,  x ) y sustituir su expresión en la otra ecuación para así ir determinando el valor de cada una de las variables.

En este caso, despejando el valor de x de la ecuación 1 se obtiene:

x= 48 -y -z Ecuación 4

Reemplazando esta expresión en la ecuación 2:

2*[(y+10) + (z+10)]= (48 -y -z+10) + 6

y aislando la variable y obtienes:

2*[y + z +10 +10]= 48 -y -z +10 +6

2*[y + z +20]= 64 -y -z

2*y + 2*z +40= 64 -y -z

2*y + y= 64 -z -2*z -40

3*y= 24 - 3*z

y= (24 - 3*z)÷ 3

y= 8 - z Ecuación 5

Reemplazando esta expresión en la ecuación 4:

x= 48 - (8 -z) -z

y resolviendo se obtiene el valor de x, es decir, la edad del padre:

x= 48 -8 +z +z

x=40

Entonces, la edad del padre es 40 años.

Ahora, reemplazando la ecuación 5 y el valor de x en la ecuación 3 se obtiene:

(40-z)= 3*(8 -z -z) +26

Resolviendo:

40 -z= 3*(8 -2*z) +26

40 -z= 3*8 - 3*2*z +26

40 -z= 24 -6*z +26

-z + 6*z= 24 + 26 - 40

5*z= 10

z= 10÷ 5

z=2

Entonces, la edad del hijo menor es 2 años.

Finalmente, reemplazando el valor de z en la ecuación 5 se obtiene:

y= 8 - 2

y= 6

Por lo que, la edad del hijo mayor es 6 años.
