Answer:

71. 19  72. 100  73. 9  74.1  75. 90  76. 4

Step-by-step explanation:

#71.

Start with 2b-a

Plug in the given numbers where the variables are.

Now the equation is 2(12) - 5

Solve 2(12) - 5

2(12) = 24      24 - 5 = 19

#72.

Start with d(ab-c)

Plug in the given numbers where the variables are.

Now the equation is 2((5×12) - 10)

Solve in the parenthesis first.

5×12= 60    60-10=50    2(50)= 100

#73.

Start with 3+ [tex]\frac{b}{d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is 3+ [tex]\frac{12}{2}[/tex]

Solve.

[tex]\frac{12}{2}[/tex] = 6    3+6 = 9

#74.

Start with [tex]\frac{4a}{b+4d}[/tex]

Plug in the given numbers where the variables are.

Now the equation is [tex]\frac{4(5)}{12+(4x2)}[/tex]

Solve.

4(5)= 20    

(4×2)= 8    12+8= 20

Now the fraction is  [tex]\frac{20}{20}[/tex] = 1

#75.

Start with 2a² - c

Plug in the given numbers where the variables are.

Now the equation is 2(5)² - 10

Solve 2(5) = 10      10² = 100  100-10= 90

#76.

Start with b - c + d

Plug in the given numbers where the variables are.

Now the equation is 12 - 10 + 2

Solve.

12 - 10 = 2     2 + 2 = 4

Answer:

  a) n(A∪B) = 20

  b) n(A) = 31

Step-by-step explanation:

The relevant formula is ...

  n(A∪B) = n(A) +n(B) -n(A∩B)

__

a) n(A∪B) = 5 +18 -3 = 20

b) 32 = n(A) +14 -13   ⇒   n(A) = 31

Answer:

20,600,000,000

Step-by-step explanation:

When writing a number in standard notation from scientific notation, counting decimal places is important. In this case, the exponent of 10 is 10. That means the decimal place must be moved 10 places; since it is positive the decimal place should be moved to the right. Finally, fill any empty spaces when moving the decimal point with zeros.

Step-by-step explanation:

There are 13 clubs in the deck of 52 cards. That makes the probability of the first card being a club 13/52, which reduces to 1/4.

For the second card, there are 12 clubs in the 51 that remain, so the probability it's a club is 12/51, or 4/17.

There are now 11 clubs in the remaining 50, so the probability the third card is a club is 11/50.

Finally, you have 10 clubs out of 49 cards, making the probability that the 4th card is a club is 10/49.

To get the probability of this whole scenario, just multiply the four fractions (and simplify).

Answer:

Step-by-step explanation:

P(Clubs) = 13C4 // 52C4

The order doesn't matter in either case.

13 * 12 * 11 * 10

============

52 * 51 * 50 * 49

P(4 cards all clubs) = 11/4165

P(4 cards all clubs) = 0.002641

All the elements of the given set {2,4,8,...,256} are - {2, 4, 8, 16, 32,64, 128, 256} that are total 8 in numbers.

The set is formed by the number of objects in a particular manner, these objects are called elements of the set. The elements of the set are written inside a curly bracket separated by a comma in a particular or specific order.

There are two methods to represent the set and its elements that are:

in this case, {[tex]2^{1},2^{2},2^{3},2^{4},2^{5},2^{6},2^{7},2^8[/tex]} as we know,

so the set notation would be :

= {x:x = [tex]2^{n}[/tex], n∈N and 1 ≤ n ≤ 8}

The listing method:  {2, 4, 8, 16, 32,64, 128, 256}\

Thus, the above mention set is all the elements of the set.

Answer:

B

Step-by-step explanation:

the answer is (15+11)+4=15+(11+4)

The expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.

The cumulative property states that if the position of the numbers when they are in addition is changed then it will not affect the final result of the addition. If altering the operands' order has no effect on the outcome, the binary operation is commutative in mathematics.

The commutative property basically states that x+y can be flipped yet have the same meaning so x+y = y+x ~.

In the option B the expression (15+11) + 4 = 15 + (11+4) representing the cumulative property. On changing the summation terms the final answer will not change.

Therefore, the expression (15+11) + 4 = 15 + (11+4) best represents the commutative property of addition. The correct option is B.

Answer:

3x - y = -6 is answerrrrrrrrrr

Answer:

equation is y= 50 + 3f

57F

15 Minutes

Step-by-step explanation:

a) the equation above because 50 is the starting temp and every 3 minutes is another degree F

b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.

c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.

Answer:

[tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}inches}[/tex]

Step-by-step explanation:

Hi there!

100 inches per minute

⇒ [tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}[/tex]

To change this into feet per minute, we need to cancel out the "inches" unit and replace it with feet. The "minute" unit stays the same.

To cancel inches out and leave feet remaining, we must multiply [tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}[/tex] by a fraction that has inches in the denominator and feet in the numerator:

[tex]\displaystyle\frac{100 \hspace{4}inches}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}inches}[/tex]

Notice how inches cancels out:

[tex]\displaystyle\frac{100 \hspace{4}}{1 \hspace{4}minute}*\frac{1 \hspace{4}foot}{12 \hspace{4}}\\\\= \displaystyle \frac{100 \hspace{4} feet }{12 \hspace{4} minutes} \\\\= \displaystyle \frac{25 \hspace{4} feet }{3 \hspace{4} minutes}[/tex]

If the vectors [tex]\{\mathbf v_1,\mathbf v_2,\ldots,\mathbf v_p\}[/tex] span [tex]\mathbb R^n[/tex], then any vector [tex]\mathbf x\in\mathbb R^n[/tex] can be expressed as a linear combination of these vectors. This means there exist scalars [tex]\{c_1,c_2,\ldots,c_p\}[/tex] such that

Step-by-step explanation:

h=3 cm

proportional rectangle:

   height=12

 width=5*4

          =20 cm

Step-by-step explanation:

it's really simple.

g(f(x)) means that you use x to create f(x), and then you use this f(x) as argument in g(x).

with our functions here it means in general to use f(x) = 4 - x as argument (instead of purely x) in g(x).

g(f(x)) = 5×(4 - x) - 2 = 20 - 5x - 2 = 18 - 5x

that is the whole trick.

now, when we have a specific x value (x = 6 in our example here), it can be even simpler.

we need to "feed" 6 into f(x).

4 - x = 4 - 6 = -2

so, f(6) = -2

now this -2 becomes the argument for g(x).

5×(-2) - 2 = -10 - 2 = -12

so, g(f(6)) = -12

let's check for control and also use the functional definition of g(f(x)) we established above :

18 - 5×6 = 18 - 30 = -12

the same result, so all correct.

The milk costs "7.75" for one portion cost. A further solution is provided in the below section.

The given information in the question is:

Milk per gallon,

= $2.48

We know that,

→ [tex]1 \ gallon = 128 \ ounces[/tex]

then,

→ [tex]128 \ ounces \ cost =[/tex] $[tex]2.48[/tex]

hence,

→ The 4 ounces of milk cost will be:

= [tex]\frac{2.48}{128}\times 4[/tex]

= [tex]\frac{9.92}{128}[/tex]  

= [tex]0.0775[/tex]

or,

= [tex]7.75 \ cents[/tex]

Thus the above is the correct answer.
