Select the correct answer.
Evaluate the following expression when x= -5 and y= 25
5|x| - y3 over x
A. 620
В. 3,120
C. -3,130
D. -630

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

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.

Ingrid collected 3 times as many Food boxes as she did cans of Food.

Step-by-step explanation:

Ingrid collected 6 cans of food from the food bank.

Ingrid collected 18 boxes of food from the food bank.

In order to determine the relationship

let cans of food = x = 6

So the boxes of food will be 3x = 3*6 = 18

So the relation between Cans of food and boxes of food will be

Ingrid collected 3 times as many boxes as she did cans

Step-by-step explanation:

4. Not enough info, the shape is cut off. Are there 4 sides or 5? If there's a 5th side, is it slanted or parallel to the one labeled 10 ft?

5. The circle has a radius of 7 m, so its area is

π (7 m)² = 49π m²

Subtract from this the area of the white triangle. It has a base length equal to the diameter (i.e. twice the radius) of the circle, and a height equal to the radius, so its area is

1/2 (14 m) (7 m) = 49 m²

So the area of the shaded region is (49π - 49) m², or 49 (π - 1) m².

6. The rectangle has length 14 yd and height equal to the diameter of the circular cutout, 10 yd, so its area is

(14 yd) (10 yd) = 140 yd²

The circular cutout is a semicircle with radius 5 yd, so its area is

1/2 π (5 yd)² = 25π/2 yd²

Then the area of the shaded region is (140 - 25π/2) yd², or 1/2 (280 - 25π) yd².

7. The circle has radius 13 in, so its area is

π (13 in)² = 169π in²

The triangle has height 23 in and length 12 in, so its area is

1/2 (23 in) (12 in) = 138 in²

Then the area of the shaded region is (169π - 138) in².

8. The shaded region is a rectangle with a smaller rectangular cutout. The larger rectangle has height 19 cm and length 18 cm + 16 cm = 34 cm, so its area is

(19 cm) (34 cm) = 646 cm²

The smaller rectangular cutout has length 16 cm and height 19 cm - 16 cm = 3 cm, so its area is

(16 cm) (3 cm) = 48 cm²

Then the area of the shaded region is 646 cm² - 48 cm² = 598 cm².

9. The semicircular piece has radius 3 m, so its area is

1/2 π (3 m)² = 9π/2 m²

The triangle has height equal to the semicircle's diameter, 6 m, and length 9 m, so its area is

1/2 (6 m) (9 m) = 27 m²

Then the area of the shaded region is (9π/2 + 27) m², or 1/2 (9π + 54) m².

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:

0.65 grams

Step-by-step explanation:

0.42 + 0.23 = 0.65

The total weight of both salt and pepper is 0.65 grams.

Decimals are one of the types of numbers, which has a whole number and the fractional part separated by a decimal point. The dot present between the whole number and fractions part is called the decimal point.

Given that, you have 0.42 grams of salt and add 0.23 grams of pepper.

Total weight = 0.42+0.23

= 0.65 grams

Therefore, the total weight of both salt and pepper is 0.65 grams.

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.

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.

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)
