The sum of two numbers is 64 and the difference is 6. What are the numbers?

Answer: 1

Step-by-step explanation:

You are welcome :)

The two angles are supplementary, so their measures add to 180º. Use this to solve for x :

(3x + 20) + x = 180

4x + 20 = 180

4x = 160

x = 40

Then the larger angle has measure

(3(40) + 20)º = (120 + 20)º = 140º

Answer:

21.06

Step-by-step explanation:

Answer:    8.3 or C  

Eplanation: This is because a half life is 50 percent of a normal life so 50 percent divided by 6 is 8.3

[tex]8.3[/tex]% is the approximate decay rate of the element after the first day.

What is Radioactive decay ?

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles.

What is decay rate?

The rate of decay, or activity, of a sample of a radioactive substance is the decrease in the number of radioactive nuclei per unit time.

According to question, a radioactive element has a half-life of six days.

A half- life is [tex]50[/tex]% of a normal life.

So, the approximate decay rate of the element after the first day

[tex]=\frac{50}{6}[/tex]% [tex]=8.3[/tex]%

Hence, we can conclude that [tex]8.3[/tex]% is the approximate decay rate of the element after the first day.

Answer:

168

Step-by-step explanation:

Answer:

Liam would save $168.

What I did:

Multiply the $12 and the 14 weeks. this will give you $168.

Answer:

a) 2.09167

b) 0.2

c) 130 correspondents

d) 5.38 hours per day

e) 69%

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

Mean = 2.98hrs/day, Standard Deviation = 2.4

a) What is the Z score for a person who watches more than 8 hrs/day.

z = 8 - 2.98/2.4

= 2.09167

b) What proportion of people watch 5 hrs/day or more television?

z = 5 - 2.98/2.4

z = 0.84167

Determining the Probabilityvalue from Z-Table:

P(x<5) = 0.80001

The proportion of people watch 5 hrs/day or more television

P(x>5) = 1 - P(x<5) = 0.19999

Approximately = 0.2

c) How many does this correspond to in the sample?

From the question above, we are told that: there are 650 GSS respondents in 2006 watched television

Hence the proportion that corresponds to Question b is

0.2 × 650

= 130 correspondents

Therefore, 130 correspondents watch 5 hrs a day or more television

d) What number of television hours per day corresponds to a Z = +1.

z score formula is given as:

z = (x-μ)/σ

Z = +1

x = unknown

Mean = 2.98

Standard deviation = 2.4

Hence:

1 = x - 2.98/2.4

Cross Multiply

1 × 2.4 = x - 2.98

2.4 = x - 2.98

2.4 + 2.98 + x

= 5.38 hours per day.

e)What is the percentage of people who watch between 1 and 6 hours of television per day?

For x = 1

z = 1 - 2.98/2.4

z = -0.825

Probability value from Z-Table:

P(x= 1) = 0.20469

For x = 6

z = 6 - 2.98/2.4

z = 1.25833

Probability value from Z-Table:

P(x = 6) = 0.89586

The percentage of people who watch between 1 and 6 hours of television per day is calculated as:

P(x = 6) - P(x = 1)

0.89586 - 0.20469

= 0.69117

Converting to percentage,

0.69117 × 100%

= 69.117%

To the nearest whole number = 69%

Therefore, 69% of the people who watch between 1 and 6 hours of television per day

Answer:

b=4

Step-by-step explanation:

g(x)=x^2+bx+11

When x = -1  g(x) = 8

8 = (-1)^2 +b(-1) +11

8 = 1 -b+11

Combine terms

8 = 12-b

Subtract 12 from each side

8-12 = 12-b-12

-4 = -b

Multiply by -1

4 = b

Answer:

There are 32 tablespoons in a pint

Answer:

Step-by-step explanation:

1 cup = 240 mL

1 pint = 2 cups = 480 mL

1 tbsp = 15 ml

1 pint = 480 mL / 15 tablespoons

1 pint = 32 tablespoons.

These numbers are approximations. It depends on what your conversions really are. However the answer should be very close to 32 tablespoons.

Answer:

there are 600 cm in 6 meters

Answer: 600 cm

Step-by-step explanation:

100cm = 1 m

Then ? cm = 6m

Since cm is smaller than m, cm would need more to be equal or equivalent to m. Therefore we say, what multiply by 1m gives you 6m? Because they are asking for 6m. Whatever you do to one side you do to the other.

6(100)cm = 6(1) m

600cm = 6m

Answer:

[tex]a=\frac{m}{(q+r^2)}[/tex]

Step-by-step explanation:

We begin with the equation [tex]qa+r^2a=m[/tex] for which we need to solve for a.

The first thing that we can do is to factor out the a from both terms on the left side of the equation

[tex]qa+r^2a=m\\\\a(q+r^2)=m[/tex]

Then we can divide each side by [tex](q+r^2)[/tex] to isolate a

[tex]a(q+r^2)=m\\\\a=\frac{m}{(q+r^2)}[/tex]

A. [tex] Area = \frac{1}{2}(2x^2 - 2x - 24) [/tex]

B. [tex] Area = 3.75 in^2 [/tex]

Step-by-step explanation:

A. [tex] Area = \frac{1}{2}bh [/tex]

Where,

[tex] b = 2x + 6 [/tex]

[tex] h = x - 4 [/tex]

Plug in the values to get a polynomial that represents the area of the tool

[tex] Area = \frac{1}{2}(2x + 6)(x - 4) [/tex]

[tex] Area = \frac{1}{2}(2x(x - 4) + 6(x - 4) [/tex]

[tex] Area = \frac{1}{2}(2x^2 - 8x + 6x - 24) [/tex]

[tex] Area = \frac{1}{2}(2x^2 - 2x - 24) [/tex]

B. To find area, when x = 4.5 in, plug in the value of x into the equation for the area of the tool.

[tex] Area = \frac{1}{2}(2(4.5)2 - 2(4.5) - 24) [/tex]

[tex] Area = \frac{1}{2}(2(20.25) - 9 - 24) [/tex]

[tex] Area = \frac{1}{2}(40.5 - 9 - 24) [/tex]

[tex] Area = \frac{1}{2}(7.5) [/tex]

[tex] Area = 3.75 in^2 [/tex]

There are [tex]9[/tex] tens in [tex]192[/tex].

The system or method of writing certain numbers with the help of some rules is called a number system.

Usually, we write numbers in two ways i. e. national and international.

we write these numbers using periods.

example of the national number system is [tex]23, 56, 78, 999[/tex] that it is read as twenty-three crore fifty-six lakhs seventy-eight thousand nine hundred ninety-nine.

example of an international number system is [tex]456,456[/tex]  , read as four hundred fifty-six thousand four hundred fifty-six.

On expanding [tex]192[/tex] we  get ;

[tex]192 = 100 + 90 + 2[/tex]

which contains  9 at its tens place .

Thus, on expanding we get [tex]9[/tex] tens.
