Answer:
(2, 7 )
Step-by-step explanation:
Substitute the coordinates of each pair into the left side of the inequality and compare the result to the right side.
(- 5, 1 )
- 15 + 4 = - 11 < 20 ← not a solution
(0, - 3)
0 - 12 = - 12 < 20 ← not a solution
(- 4, 2 )
- 12 + 8 = - 4 < 20 ← not a solution
(2, 7 )
6 + 28 = 34 > 20 ← solution
The ordered pair which is correct for the given inequality will be equal to (2, 7). Hence, option D is correct.
What is inequality?Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.
As per the given information in the question,
The given inequality is,
3x + 4y > 20
For point (-5, 1)
3(-5) + 4(1) > 20
-11 > 20, this is incorrect.
For point (0, -3)
3(0) + 4(-3) > 20
-12 > 20, this is incorrect.
For points (-4, 2)
3(-4) + 4(2) > 20
-4 > 20, this is incorrect.
For points (2, 7)
3(2) + 4(7) > 20
34 > 21, this is correct.

Sonia es apicultora y en su planta de envadasado la maquina envasa 1920 tarros por hora, que luego se agrupan por tamaños; los frascos grandes se agrupan en cajas de una docena y los medianos en cajas de 20 unidades. ¿ si la maquina solo envasara frascos de un tipo , cuantas cajas de frascos grandes envasaria cada hora? Y de frascos medianos?
Answer:
En una hora, la máquina podría envasar 160 cajas de frascos grandes, o 96 cajas de frascos medianos.
Step-by-step explanation:
Si la maquina solo envasara frascos de un tipo, y pudiese envasar 1920 tarros por hora, para determinar cuantas cajas de frascos grandes envasaría cada hora hay que realizar el siguiente cálculo:
1920 / 12 = X
160 = X
Así, en una hora, la máquina envasaría 160 cajas de frascos grandes.
Por otra parte, en caso de envasar frascos medianos, el cálculo sería el siguiente:
1920 / 20 = X
96 = X
Por ello, la máquina envasaría 96 cajas de frascos medianos en una hora.
Metro cable tv tuvo ventas de 2500000 en su primer año de funcionamiento. Si a partir de entonces las ventas aumentaron 12% con respecto al año anterior, calcule las ventas de la empresa en el quinto año y las ventas totales durante los primeros 5 años de operación
Explicación paso a paso:
Dado
Principal = 2,500,000
Tasa = 12% (anual)
tiempo = 5 años
Incremento después del primer año = 12% de 2.500.000
= 12/100 * 2,500,000
= 12 * 25000
= 300.000
El monto al final de los 5 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 5
A = 2500000 (1,12) ^ 5
A = 2500000 (1,7623)
A = 4.405.854,208
Por lo tanto, las ventas totales durante los primeros 5 años de operación son 4.405.854,208
Obtenga la cantidad obtenida en el quinto año
El monto al final de los 4 años se calculará utilizando la fórmula de interés compuesto;
A = P (1 + r) ^ n
A = 2500000 (1 + 0,12) ^ 4
A = 2500000 (1,12) ^ 4
A = 2500000 (1,5735)
A = 3.933.798,4
Utilidad obtenida en el quinto año = 4.405.854,208 - 3.933.798,4
A = 4.405.854,208 - 3.933.798,4
A = 472.055,808
Por lo tanto, la ganancia obtenida en el quinto año es de 472,055.808
Monto realizado en el quinto año = Principal + intereses en el quinto año
Monto realizado en el quinto año = 2500000 + 472,055.808
Monto realizado en el quinto año = 2,972,055.808

Fahim is 6 feet tall. At noon, he stands with the sun behind him casting a shadow. The distance from the top of Fahim's head to the furthest tip of the shadow is 13 feet. A right triangle with side length 6 feet, s, and hypotenuse 13 feet. [Not drawn to scale] What is the length of Fahim's shadow? Round to the nearest tenth of a foot. 7.0 feet 8.5 feet 11.5 feet 14.3 feet
Answer: 11.5 feet
Step-by-step explanation:
We should note that for a right angles triangle, the square of the hypothenuse equals to the square of the opposite side and its adjacent. This can be expressed as:
Let the length of Fahims shadow be x
hypotenuse² = opposite² + adjacent ²
13² = 6² + x²
169 = 36 + x²
x² = 169 - 36
x² = 133
x =✓133
x = 11.53
= 11.5 feet to nearest tenth
Answer:
11.5 feet

Find Percent of a Number - Instruction Level
During a basketball game, DeShawn made 24 baskets out of 30 shots. Cody made 18 baskets
out of 20 shots. Who made a greater percent of their shots?
) What percent of his shots did DeShawn make?
Answer:
1. Cody made a greater percentage (i.e 90%) of his shots
2. Deshown made 80% of his shots
Step-by-step explanation:
To know who have a higher percentage, let us calculate their individual percentage. This is illustrated below:
For Deshown,
He made 24 baskets out of 30 shots.
The percentage of shot made = 24/30 x 100 = 80%
For Cody,
He made 18 baskets
out of 20 shots

George purchased a concert ticket on a web site. The original price of
the ticket was $85. He used a coupon code to receive a 15% discount.
The website applied a 10% service fee to the discounted price. George's
ticket was less that the original price by what percent?
15%
10%
6.5%
8.5%
Answer:
6.5%
Step-by-step explanation:
The original price of the ticket was 100% of the price of the ticket.
The 15% coupe reduced the price to 85% of the price of the ticket.
The 10% fee on the discounted price adds 10% of 85% to 85%, so it adds 8.5% to 85%. By adding the fee he is at 93.5% of the original price.
100% - 93.5% = 6.5%
The overall percent off compared to the original price was 6.5%.
Answer: 6.5%

Slope of AC: -1.5x
Slope of XY: -2/3x
Neither: Why? The slope of AC and XY are not the same, so they are not parallel. They are not perpendicular either because being perpendicular means that the slopes must be the negative reciprocal, which it is not.

Find the value of x in the figure given that SU = 133.
A) 7
B) 9
C) 11
D) 8
Answer:
The answer is 9 (B)
Step-by-step explanation:
I got 9 because you have to plug in answer (7, 9, 11, 8) in each equation than add them both together. I first plugged in 7 for x in the equation 9x-5. I got 58. I plugged in 7 for x in the equation 5x+12 and got 47. When I added both the answers together I got 105. The answer was to low because SU has to be 133. I plugged in 9 for x in both equations then added them both and got 133 for SU. I hope this helps.

Teresa has a $100 gift card to her favorite restaurant. Each day, she uses her gift card to buy the same lunch for $8.50. Colin has a $75 gift card to the same restaurant. His lunches cost $6 each. Which inequality shows Teresa's gift card balance to be greater than Colin's gift card balance?
Answer:
Thinking about the equation and the depth I believe that the inequality would be:
100 is greater than 75. If not that I would think the answer is 100-8.50 is greater than 75-6. The last resort would be 12 is greater than 11.
