Answer:

The simplified answer to the given equation is 6√2

Step-by-step explanation:

First, we must simplify the radicals in the equation.

√2 = 1.414213562

∛2 = 1.25992105

Now, we divide these numbers. You can divide it this way or you can divide it using a calculator.

√2 ÷ ∛2 = 1.122462048

Now, let;s look at our answer choices. We can immediately cross out A because 1/4 equals 0.25. Let's look at the others.

6√2 = 1.22462048

So, our answer here is answer choice B.

Answer:

Using the given information, the measurement of ∠P is 41° and the measurement of ∠Q is 49°

Step-by-step explanation:

Complementary angles are angles that have a sum measurement of 90°. So, the measurement of ∠P and the measurement of ∠Q will have a sum of 90° because they are complementary angles.

So, let's set up an equation where we add the two measurements and equal them to 90.

(8x + 1) + (9x + 4) = 90

Combine like terms.

17x + 5 = 90

Subtract 5 from both sides of the equation.

17x = 85

Divide 17 from both sides of the equation.

x = 5

Now that we have the value of x, let's plug in this value for each angle to find their measurement.

m∠P = 8(5) + 1 = 40 + 1 = 41

m∠Q = 9(5) + 4 = 45 + 4 = 49

So, the measurement of ∠P is 41° and the measurement of ∠Q is 49°

The value of ∠P=41° and ∠Q= 49°.

Given to us:

∠P = 8x + 1,

∠Q = 9x + 4,

Complementary angles are the angles whose measures sums to 90°.

As given in the question ∠P and ∠Q are complementary angles, therefore we can write it as;

[tex]\angle P + \angle Q = 90^o[/tex]

Putting the value of ∠P and ∠Q,

[tex](8x + 1) + (9x + 4) = 90\\17x + 5 = 90\\17x = 90 - 5\\\\x = \dfrac{85}{17}\\\\x= 5[/tex]

Now using the value of x, solve ∠P and ∠Q; For ∠P

[tex]\angle P= 8x+1\\[/tex]

Putting the value of x,

[tex]\angle P= 8x+1\\\angle P= (8\times 5 )x+1\\\angle P= 40+1\\\angle P= 41[/tex]

For ∠Q,

[tex]\angle P= 9x+4\\[/tex]

Putting the value of x,

[tex]\angle Q= 9x+4\\\angle Q= (9\times 5 )x+4\\\angle Q= 45+4\\\angle Q= 49[/tex]

Hence, the value of ∠P and ∠Q are 41° and 49° respectively.

Answer:

2/12

Step-by-step explanation:

You have 12 possible outcomes. Greater than 10 gives you 2 outcomes. 2/12

Answer:

1/6

Step-by-step explanation:

There are 12 equally likely outcomes, so the total number of possible outcomes is 12.

There are 2 numbers greater than 10: 11 and 12.

The number of desired outcomes is 2.

p(event) = (number of desired outcomes)/(total number of possible outcomes)

p(greater than 10) = 2/12 = 1/6

Answer:

Both/Neither.

Step-by-step explanation:

For the circle, the area is π(6)^2= 36π. 3/4 of that is 27π. Now, for the ring, area of outer circle is 36π. The area of inner circle is 9π. So, area of ring is 27π. That means, both will take the same amount of paint.

Answer:

17. D

11. 147 deg

Last problem: 2nd answer

Step-by-step explanation:

17. D

All parallelograms have 4 sides, so all parallelograms are quadrilaterals.

11.

m<B = m<D = 33

m<A + m<B + m<C + m<D = 360

m<A + 33 + m<C + 33 = 360

m<A + m<C = 294

m<A = m<C = (1/2) * 294

m<C = 147

Last problem:

If in a quadrilateral, a pair of opposite sides is both parallel and congruent, then the quadrilateral is a parallelogram. In the second choice, the same pair of sides is parallel and congruent, so this is the answer.

Answer:

Area = 36 sq units

Step-by-step explanation:

An isosceles trapezoid have two triangles and probably a rectangle or a square.

To find the area, let's determine the height of the trapezoid.

The base length of one of the triangle

= (15-9))2

= 6/2 = 3

The height will be x

X /sin 45= 3 / sin 45

X= 3

The area of the trapezoid

= 1/2(a+b)h

Where a = 15

b = 9

h = 3

Area= 1/2(15+9)3

Area= 1/2 *24*3

Area= 12*3

Area = 36 sq units

Answer:

p(x) = x⁶- 2x⁵- 10x⁴ + 20x² + 9x - 18

d(x) = (x - 2)

r = 0

f(x) = x⁵ - 10x³ + 9

Step-by-step explanation:

From the synthetic division given in the question,

Polynomial p(x) = x⁶- 2x⁵- 10x⁴ + 20x² + 9x - 18

Divisor d(x) = (x - 2)

After synthetic division of this polynomial by 2 we get the remainder,

r = 0

And the new polynomial f(x) that can be used further to find the other factors will be,

f(x) = x⁵ + (0).x⁴ + (-10)x³ + (0).x² + 9

f(x) = x⁵ - 10x³ + 9

Answer:

90 gallons

Step-by-step explanation:

5 people at 9 minutes each = 45 minutes

2 gallons per minutes * 45 minutes

90 gallons

Answer:

90 Gallons

Step-by-step explanation:

So to start we know that

a. every 1 min = 2 gallons

b. 5 ppl shower for 9 minutes each (on average)

so we can solve we multiplying amt. of ppl showering and the mins. they shower which is 5 and 9 respectively => and we get 45 minutes taken.

We know that each minute equals 2 gallons so we simply multiply 45 and 2 = 90 => and thus, we have our answer of 90 gallons.

Answer:

The perimeter of the rectangle is 165.8cm

Step-by-step explanation:

Area of a rectangle = length × width

Area = 524.4m²

length = 6.9m

524.4 = 6.9 × width

width = 524.4 / 6.9

width = 76m

Perimeter of a rectangle =

2(length ) + 2(width)

length = 6.9m

width = 76m

Perimeter = 2( 6.9) + 2(76)

= 13.8 + 152

The final answer is

= 165.8cm

Answer:

Step-by-step explanation:

Let x be the random variable representing the time (in minutes) taken for a dose of a certain drug to be effective as a sedative on lab animals. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,

z = (x - µ)/σ

Where

x = sample mean

µ = population mean

σ = standard deviation

From the information given,

µ = 1

σ = √variance = √0.01 = 0.1

the probability that the time taken for a randomly selected animal is between 1 and 1.1 minutes is expressed as

P(1 ≤ x ≤ 1.1)

For x = 1,

z = (1 - 1)/0.1 = 0

Looking at the normal distribution table, the probability corresponding to the z score is 0.5

For x = 1.1

z = (1.1 - 1)/0.1 = 1

Looking at the normal distribution table, the probability corresponding to the z score is 0.84

Therefore,

P(1 ≤ x ≤ 1.1) = 0.84 - 0.5 = 0.34

The the proportion of animals for which the time taken is between 1 and 1.1 minutes is 0.34

Answer:

144

Step-by-step explanation:

We will use permutations to solve this problem

There are 4 pairs each having a male and a female.

The total number of sample points is 4! = 4*3*2*1= 24

He chooses the male first  then the number of sample space he is left with are 3! = 3*2*1=6

The total number of ways he can select is 4! 3! = 24 * 6= 144

Another way of finding it out is

he has 4 pairs  each having a male and a female so he chooses 1st male then he would choose from this

4 female choices*3 male choices * 3 female choices *2 male choices *2 female choices *1 male choices *1 female choices *= 4*3*3*2*2*1*1= 144

The zookeeper can feed all the animals in 144 ways

The number of different animals is given as:

[tex]n = 4[/tex]

The number of ways to feed any of the 4 male animals is:

[tex]Ways = 4![/tex]

Expand

[tex]Ways = 4 \times 3 \times 2 \times 1[/tex]

[tex]Ways = 24[/tex]

From the question, we understand that the female of the particular animal cannot be selected (yet).

So, there are 3 female animals left.

The number of ways to feed any of the 3 female animals is:

[tex]Ways = 3![/tex]

Expand

[tex]Ways = 3 \times 2 \times 1[/tex]

[tex]Ways = 6[/tex]

So, the number (n) of ways to feed all the animals is:

[tex]n = 24 \times 6[/tex]

[tex]n = 144[/tex]

Hence, he can feed all the animals in 144 ways

Answer:

The two inequalities are;

P ≤ 90e^(0.047t)

P ≤ 270 + 100·t

Step-by-step explanation:

The parameters given for the testing of the new growth inhibitor are;

The growth rate of the bacteria = 4.7% exponentially

The growth inhibitor lowers the growth rate

The population of bacteria after time, t = P

The increase in the number of bacteria per unit time in the 100

The maximum number of bacteria in the standard tube = 270

Therefore, the number of bacteria after the first filling of the tube is P ≤ 270 + 100·t

The equation for exponential growth is [tex]A_0 e^{kt}[/tex]

Where:

A₀ = Initial population = 90

k = Percentage growth rate as percentage

t = Time

The equation for the population of bacteria under the influence of the inhibitor is therefore;

P ≤ [tex]90 \times e^{0.047 \cdot t}[/tex] which is P ≤ 90e^(0.047t).

P≤270+100t

Answer:

a) x = 5

b) x = 4

Step-by-step explanation:

a) x:2 = 10:4

Product of extremes = Product of means

=> x*4 = 10*2

=> 4x = 20

Dividing both sides by 4

=> x = 5

b) 3:x = 6:8

Product of extremes = Product of Means

=> 3*8 = 6*x

=> 24 = 6x

Dividing both sides by 6

=> x = 4

Answer:

Solution,

[tex]a. \: \: \frac{x}{2} = \frac{10}{4} \\ \: \: or \: x \times 4 = 10 \times 2 \: ( \: cross \: multiplication) \\ \: \: or \: 4x = 20 \\ or \:x = \frac{20}{4} \\ \: \: \: x = 5[/tex]
