Answer:

2.4 hours

Step-by-step explanation:

Answer:

10% OF a 24 hour day is 2.4 hours

Step-by-step explanation:

10x24/100= 2.4

Answer:

1. 78.22%

2. 0.342%

3. 21.77%

Step-by-step explanation:

To find the percentage, you multiply the fraction of those tested positive/negative (based on the question) out of the total by 100%.

1. [tex]\frac{970}{1240}[/tex] × 100% = 78.22% (2 d.p.)

2. [tex]\frac{30}{8760}[/tex] × 100% = 0.342% (3 d.p.)

3. [tex]\frac{270}{1240}[/tex] × 100% = 21.77% (2 d.p.)

(7) n = ⁴/₃

(8) x = -5

(9) d = ³/₂

(10) v = -20

Step-by-step explanation:

Answer:

244

Step-by-step explanation:

We will see that the evaluated expression is equal to 244.

Evaluating an expression just means that we need to replace the variables by the wanted numbers.

Here we need to evaluate:

2(s+t)³-6

In t = 2 and s = 3, replacing these in the expression we get:

2(3+2)³- 6 = 2*(5)³ - 6 = 2*125 - 6 = 244

So the evaluated expression is equal to 244.

Answer:

the answer is x=3

Step-by-step explanation:

-3x=1-7

-3x=-6

-x=-6+3

-x=-3

x=3

Answer: 3

Step-by-step explanation:

Answer:

x²-10x+25

Step-by-step explanation:

expand the expression

(x-5)²

(x-5)(x-5) distribute

x²-5x-5x+25

combine like terms

x²-10x+25

if you get x^2-25 then you're only squaring the x and 5, you have to square the whole equation (x-5)(x-5) is doing (x-5)^2. for example, if you just had (5)^2 you would take the whole "equation" which is 5 and times that equation by itself.

Answer:

$96

Step-by-step explanation:

Answer:

The final price after deducting the percent of discount would be $24.

Answer:

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

Plan A is better if used for more than 5 months (5 - ∞), plan B for 1 - 4 months

Step-by-step explanation:

x represents months

Plan A : f(x) = 25 + 8x

Plan B : f(x) = 5 + 12x

The equilibrium is when both of these functions have the same value

25 + 8x = 5 + 12x

4x = 20

x = 5

Now we compare these two plans before the 5 months,

e. g. when x = 2

The cost of plan A: 25 + 8x = 25 + 8 * 2 = 41$

The cost of plan B: 5 + 12x = 5 + 12 * 2 = 29$

Since 41$ > 29$, for 1-4 months plan B is a cheaper option, then after 5 months the costs of these two plans are equal and then plan A will be the cheaper aka less expensive option.

Answer:

(2b+3c) × (2a-3d)

Step-by-step explanation:

plz mark as brainliest

The factors of 4ab+6ac-6bd-9cd are (2a-3d) and (2b+3c).

Factors are those numbers or expressions which when together be multiplied results the same numbers whose factors they are. It can be found for equations and expressions as well. It includes those number which divides the given number to get another factor value.

We have been given expression 4ab+6ac-6bd-9cd and we have to find the factors of the expression.

Factorization can be done as under:

Expression=4ab+6ac-6bd-9cd

=2a(2b+3c)-3d(2b+3c)

[we have to take common expression from two terms like we did above]

=(2a-3d)(2b+3c)

Hence the factors of expression 4ab+6ac-6bd-9cd are (2a-3d) and (2b+3c).

Answer:

150,000.

Step-by-step explanation:

Given that an insector found 24 defective cameras during an inspection and this is 0.016% of the total numbers of cameras inspected, to determine how many cameras were inspected the following calculation must be performed:

0.016 = 24

100 = X

100 x 24 / 0.016 = X

2,400 / 0.016 = X

150,000 = X

Thus, the total number of cameras that were inspected is 150,000.

Not a function.

Step-by-step explanation:

The vertical line test is when you run a line -vertical or AKA: up and down- through the path of a graph if the line runs through the path more than once, it has failed the vertical line test, and therefore is not a function. The graph in question fails this test, and cannot be a function.

Answer:

Step-by-step explanation:

V(cone) = 1/3· π · r² · h

V = 1/3 · π · 25 · 12

V(half-sphere) = (4/3 · π r³)/2

V = (4/3π · 125) = 261.8

English Answer: No object can resist an irresistible force. No force can move an immovable object. So if an immovable object meets an irresistible force it will move and not move.English:

Spanish Answer: Ningún objeto puede resistir una fuerza irresistible. Ninguna fuerza puede mover un objeto inamovible. Entonces, si un objeto inamovible se encuentra con una fuerza irresistible, se moverá y no se moverá.

Step-by-step explanation:

¿Qué pasaría si una fuerza imparable chocara contra un objeto inamovible? Las respuestas comunes a esta paradoja recurren a la lógica y a la semántica.

Lógica: Si existe una cosa tal como una fuerza imparable, entonces no puede existir un objeto inamovible y viceversa. Es lógicamente imposible la existencia de los objetos (una fuerza imparable y un objeto inamovible) en un mismo universo al mismo tiempo.

Semántica: Si existe una cosa tal como una fuerza imparable, entonces hablar de un objeto inamovible no tendría sentido en ese contexto y viceversa, con lo cual el asunto vendría a ser algo así como preguntar, por ejemplo, por un triángulo de cuatro lados.

Answer:

Step-by-step explanation:

radius r of cylinder = 7

circumference of cylinder = 2πr = 14π meters.

lateral area of cylinder = 14π×11 = 154π m².  This is represented by the rectangle.

area of top = πr² = 49π m²

area of bottom = area of top = 49π m²

total surface area = lateral area + 2(top area) = 154π + 2×49π = 252π ≅ 792 m²

Add 8 and 1 to get 9.

9/2 + 2/6

Reduce the fraction 2/6 to lowest terms by extracting and canceling out 2.

9/2 + 1/3

Least common multiple of 2 and 3 is 6. Convert 9/2 and 1/3 to fractions with denominator 6.

27/6 + 2/6

Since 27/6 and 2/6 have the same denominator, add them by adding their numerators.

Step-by-step explanation:

Answer:

0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Determine the probability that at least one color will be missing from the 10 selected balls.

Red missing:

Each time, there are 55 + 25 = 80 non-red balls, out of 100. So, in each of the 10 trials, 80% = 0.8 probability of not picking a red ball. The probability that no red ball is picked is given by:

(0.8)^10 = 0.1074

White missing:

55 + 20 = 75 non-white balls, out of 100, in each trial. The probability that no white ball is picked is given by:

(0.75)^10 = 0.0563

Blue missing:

45 non-blue balls, out of 100. The probability that no blue ball is picked is given by:

(0.45)^10 = 0.0003

Total:

0.1074 + 0.0563 + 0.0003 = 0.164

0.164 = 16.4% probability that at least one color will be missing from the 10 selected balls.

Conjecture: For every number x, the result of the is 2x

Step-by-step explanation:

First Number: 8

Multiply by 88: [tex]88 * 8 = 704[/tex]

Add 88: [tex]704 + 88 = 792[/tex]

Divide by 44: [tex]792/44 = 18[/tex]

Subtract 2: [tex]18 - 2 = 16[/tex]

Second: 10

Multiply by 88: [tex]88 * 10 = 880[/tex]

Add 88: [tex]880+88=968[/tex]

Divide by 44: [tex]968/44=22[/tex]

Subtract 2: [tex]22-2=20[/tex]

Third: 5

Multiply by 88: [tex]88*5 = 440[/tex]

Add 88: [tex]440+88=528[/tex]

Divide by 44: [tex]528/44=12[/tex]

Fourth: 2

Multiply by 88: [tex]88*2=176[/tex]

Add 88: [tex]176+88=264[/tex]

Divide by 44: [tex]264/44=6[/tex]

Subtract 2: [tex]6-2=4[/tex]

On a general terms:

Let the number be x.

Multiply by 88: [tex]88x[/tex]

Add 88: [tex]88x + 88[/tex]

Divide by 44: [tex]\frac{88x + 88}{44} = \frac{88x}{44} + \frac{88}{44} = 2x+2[/tex]

Subtract 2: [tex]2x + 2 - 2 = 2x[/tex]

Notice that for every input x, the result is 2x
