Answer:

(b) t+82=36

Step-by-step explanation:

When 82 is added to a number the resulting number is the same as 36.

Let t be the number in which 82 is added.

After addition the resulting number = t+82

As the resulting number is the same as 36, so,  

t+82 = 36

Hence option (b) is correct.

Answer:

[tex]\frac{12}{49}[/tex]

Step-by-step explanation:

[tex]\frac{4}{7}[/tex] ÷ 2 [tex]\frac{1}{3}[/tex]

First, change 2 [tex]\frac{1}{3}[/tex] into an improper fraction. It will make the solving process a lot easier.

2 [tex]\frac{1}{3}[/tex] = [tex]\frac{7}{3}[/tex]

So:

[tex]\frac{4}{7}[/tex] ÷ [tex]\frac{7}{3}[/tex]

Now solve by multiplying the reciprocal of [tex]\frac{7}{3}[/tex] which is [tex]\frac{3}{7}[/tex]

So:

[tex]\frac{4}{7}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{49}[/tex]

The value of 4/7 divided by 2 1/3 as requested in the task content is; 12/49.

According to the task content, the value of the expression is required.

4/7 ÷ 2 1/3

By fraction conversion, we have;

4/7 ÷ 7/3

= 4/7 × 3/7

= 12/49.

See Explanation

Step-by-step explanation:

The question is incomplete as the conversion rate for both banks is not given.

However, I'll make the following assumptions.

Bank A: $80 for 392 stellars

Bank B: $50 for 240 stellars

Solving (a) Bank with better conversion rate.

First, we need to calculate the unit rate.

Unit Rate = Dollar/Stellar

For Bank A:

Unit Rate = 392/80

Unit Rate = 4.9 Stellars to $1

For Bank B:

Unit Rate = 240/50

Unit Rate = 4.8 Stellars to $1

The bank with higher unit rate has a better exchange rate.

Hence, bank A has a better exchange rate.

Solving (b): How much more will he get if $1200 is exchanged

For Bank A:

$1 = 4.9 Stellars

Multiply both sides by 1200

$1 * 1200 = 4.9 * 1200 Stellars

$1200 = 5880 Stellars

For Bank B:

$1 = 4.8 Stellars

Multiply both sides by 1200

1200 * $1 = 4.8 * 1200 Stellars

$1200 = 5760 Stellars

Calculate their difference

Difference = 5880 - 5760

Difference = 120 Stellars

Hence, he'll get 120 more Stellars if he exchanged with bank A.

Is the following graph a function?

Yes

Step-by-step explanation:

Answer:

5 m/s^2

Step-by-step explanation:

Force = mass x acceleration

f = ma

We have the force of 10 N and the mass of 2 kg.

10 N = 2 kg a

divide by 2 on both sides to isolate the a

a = 5 m/s^2

Answer:

[tex]\boxed {\boxed {\sf a= 5 \ m/s^2}}[/tex]

Step-by-step explanation:

The formula for force is:

[tex]F=m*a[/tex]

If we rearrange the formula for acceleration (a) and divide both sides by m we get:

[tex]\frac{F}{m}=a[/tex]

The net force is 10 Newtons. Let's convert the units to make the problem easier later on.

The mass is 2 kilograms.

[tex]F=10 \ kg*m/s^2\\m= 2 \ kg[/tex]

Substitute the values into the formula.

[tex]\frac{10 \ kg*m/s^2}{2 \ kg} =a[/tex]

Divide. Note the kilograms (kg) will cancel each other out (this is why we converted the units)

[tex]\frac{10 \ m/s^2}{2}=a[/tex]

[tex]5 \ m/s^2=a[/tex]

The acceleration of the box is 5 meters per second squared.

Answer:

Probability is 0.243

Step-by-step explanation:

Probability of success p = 76% = 76/100 = 0.76

Probability of failure q = 1 - p = 1-0.76 = 0.24

We can now proceed to use Bernoulli approximation of the Binomial theorem

We have

P( X = 7) = 10 C 7 p^7 q^3

P(X = 7) = 120 * 0.1465 * 0.013824

P(X = 7) = 0.242946203712

This is approximately 0.243

Answer:

The equation of the exponential function represented by the table will be:

[tex]f(x)= 2(4)^{x}[/tex]

Step-by-step explanation:

We know the equation of exponential function such as

[tex]f(x) = ab^{x}[/tex]

Put x=0, and y=2 in the function

[tex]2 = ab^{0}[/tex]

[tex]2 = a[/tex]

Also x=1, and y=8 in the function

[tex]8 = 2b^{1}[/tex]

[tex]b=4[/tex]

Thus,

[tex]f(x) = ab^{x}[/tex]

        [tex]= 2(4)^{x}[/tex]

Therefore, the equation of the exponential function represented by the table will be:

[tex]f(x)= 2(4)^{x}[/tex]

Answer:

24

Step-by-step explanation:

Given the direction required to solve the problem :

multiply the whole number and the numerator.

Once you find the product divide that by the denominator

Simplify :

64 divided by 3/8

Multiply 64 by the numerator of the fraction :

64 * 3 = 192

Divude the result by the denominator of the fraction :

192 / 8 = 24

Hence, 64 * 3/8 = 24

The number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E​ is 10,080 ways

Step-by-step explanation:

We need to find the number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E​.

There are 9 letters in the word WONDERFUL

There is a condition that letter R is always next to E.

So, We have two letters fixed WONDFUL (ER)

We will apply Permutations to find ways of arrangements.

The 7 letters (WONDFUL) can be arranged in ways : ⁷P₇ = 7! = 5040 ways

The 2 letters (ER) can be arranged in ways: ²P₂ =2! = 2 ways

The number of ways 'WONDERFUL' can be arranged is: (5040*2) = 10,080 ways

So, the number of ways the arrangements can be made of the letters of the word'WONDERFUL' such that the letter R is always next to E​ is 10,080 ways
