Write 6 2\9 as an improper fraction. ...?

Answer:

15 :D

Step-by-step explanation:

Well, we know b = 3 so we can rewrite the expression to make it less confusing. So, we change b for 3, which is the same thing but number form:

2(3) + 9

Now we evaluate 2(3) which would be 2 x 3. 2 x 3 is 6, so we rewrite 2(3) as 6.

6 + 9

and finally, 6 + 9 is 15!

♡Hope this helps♡

The solution to 2b+9 when b=3 is 15.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

2b + 9

Now,

The value of 2b + 9 when b = 3.

= 2b + 9

= 2 x 3 + 9

= 6 + 9

= 15

Thus,

The solution is 15.

To find m∠1, you typically use geometry knowledge, including understanding the properties of polygons and triangles. Without a specific diagram or context, however, it's impossible to provide explicit steps or an exact answer for m∠1.

Without specific figures, it's impossible to determine exact angle measures. However, in general to find m∠1, you will need to draw upon your knowledge of geometry, particularly angle properties. If the angle is part of a polygon, its measure can often be determined by the other angle measures in the shape. Similarly, if the angle is part of a triangle, you could use the fact that the sum of all angles in a triangle is 180°. If angle properties like supplementary or complementary are mentioned, it means two angles add up to 180° or 90° respectively. Without a diagram or further context, I cannot provide particular steps to find m∠1.

|3x – 5| > 10 ⇔ 3x – 5 > 10 or 3x – 5 < -10.

Answer: 3x-5<-10 or 3x-5>10

Step-by-step explanation:

By applying logarithmic properties and solving a resulting quadratic equation, we find the solutions x = 3  and x = -7 for the given logarithmic equation.

To solve the logarithmic equation [tex]\( \log_4(x+5) + \log_4(x-1) = 2 \),[/tex] we can use the properties of logarithms to condense the equation into a single logarithm, then solve for x.

First, we apply the product rule of logarithms, which states that [tex]\( \log_a(b) + \log_a(c) = \log_a(bc) \)[/tex], to condense the two logarithms on the left side:

[tex]\[ \log_4((x+5)(x-1)) = 2 \][/tex]

Now, we have:

[tex]\[ (x+5)(x-1) = 4^2 \][/tex]

[tex]\[ (x+5)(x-1) = 16 \][/tex]

Next, we expand the left side of the equation:

[tex]\[ x^2 - x + 5x - 5 = 16 \][/tex]

[tex]\[ x^2 + 4x - 5 - 16 = 0 \][/tex]

[tex]\[ x^2 + 4x - 21 = 0 \][/tex]

Now, we can solve this quadratic equation for x. We can use the quadratic formula:

[tex]\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \][/tex]

For [tex]\( x^2 + 4x - 21 = 0 \), \( a = 1 \), \( b = 4 \), and \( c = -21 \).[/tex]

Plugging in these values, we get:

[tex]\[ x = \frac{-4 \pm \sqrt{4^2 - 4(1)(-21)}}{2(1)} \][/tex]

[tex]\[ x = \frac{-4 \pm \sqrt{16 + 84}}{2} \][/tex]

[tex]\[ x = \frac{-4 \pm \sqrt{100}}{2} \][/tex]

[tex]\[ x = \frac{-4 \pm 10}{2} \][/tex]

[tex]\[ x = \frac{6}{2} \][/tex] or [tex]\( x = \frac{-14}{2}[/tex]

x = 3  or x = -7

So, the solutions to the equation are  x = 3  and x = -7 .

Answer:  Option '4' is correct.

Step-by-step explanation:

Since we have given that

Total number of games =50

Firstly, he played 20 games.

Percentage of games they won = 60%

Number of games they won is given by

[tex]\dfrac{60}{100}\times 20\\\\=0.6\times 20\\\\=12[/tex]

Remaining number of games = 50-20=30

Percentage of remaining games they won = 80%

So, number of games they won is given by

[tex]\dfrac{80}{100}\times 30\\\\=0.8\times 30\\\\=24[/tex]

So, total number of games they won is given by

12+24 = 36

So, Percentage of games they won for the entire season will be

[tex]\dfrac{36}{50}\times 100\\\\=36\times 2\\\\=72\%[/tex]

Hence, Option '4' is correct.

To find y(7) given dy/dt = 4y and y(2) = 400, we can solve the differential equation, find the constant of integration, and substitute the value of t to find y(7).

To solve the differential equation dy/dt = 4y, we can separate the variables and integrate them. Starting with dy/y = 4dt, we get ln|y| = 4t + C, where C is the constant of integration.

Using the initial condition y(2) = 400, we can solve for C: ln|400| = 4(2) + C, C = ln|400| - 8. Now we can find y(7): ln|y(7)| = 4(7) + ln|400| - 8. Exponentiating both sides, we get |y(7)| = e^(28 + ln|400| - 8), and since y(7) is positive, y(7) = e^(28 + ln|400| - 8).

To write a quadratic function in standard form with zeros 6 and -8, we use the fact that the zeros of a quadratic function are the values of x for which the function equals zero. The quadratic function in standard form with zeros 6 and -8 is x^2 + 2x - 48 = 0.

To write a quadratic function in standard form with zeros 6 and -8, we use the fact that the zeros of a quadratic function are the values of x for which the function equals zero. The standard form of a quadratic function is ax^2 + bx + c = 0. Since the zeros are 6 and -8, the factors of the quadratic function will be (x - 6) and (x + 8). Multiplying these factors gives us (x - 6)(x + 8) = 0. Expanding and simplifying this expression, we get x^2 + 2x - 48 = 0. Therefore, the quadratic function in standard form with zeros 6 and -8 is x^2 + 2x - 48 = 0.

The student's question is about simplifying a complex algebraic expression that involves exponents and basic arithmetic operations. The approach to simplification entails applying the rules of exponents and arithmetic operations systematically.

The student's question appears to involve simplifying an algebraic expression with exponents and performing operations such as division and multiplication. While the question contains parts that are not directly relevant to the simplification process, we can still address the general approach to simplify an expression like a^4 divided by 2a^2 and then multiplied by 4a^4 times 8a^3, plus an additional term 1/2a plus 4a^2.

To simplify such an expression, one would apply the rules of exponents and arithmetic operations step by step. For instance, when dividing exponents with the same base, you subtract the exponents, and when multiplying, you add the exponents. This process typically results in a much simpler expression that can easily be understood or further manipulated.

The correct answer is: 8

Explanation:

Given mixed number:

[tex] 7\frac{4}{5} [/tex]

In order to convert a mixed number into a decimal number, follow the steps mentioned below:

Multiple 7 with 5 and add the numerator to the answer you get by multiplying 7 with 5. After that, write that result in the numerator and divide it with 5:

Step-1:

Multiply 7 with 5.

7*5 = 35

Step-2:

Add numerator value, which is 4 in this case, in 35

35 + 4 = 39

Step-3:

Rewrite the fraction.

[tex] \frac{39}{5} [/tex]

Step-4:

Calculate.

[tex] \frac{39}{5} = 7.8 [/tex]

Now, as the number at the tenth place after the decimal point is greater than 5, we have to round it off to 8.0.

Hence the correct answer is 8.

Rounding 7 4/5 to the nearest whole number gives 8.

To round the fraction 7 4/5 to the nearest whole number, we examine the fractional part (4/5) of the mixed number.

The fractional part, 4/5, is greater than or equal to 1/2. In such cases, when the fractional part is greater than or equal to 1/2, we round the whole number up to the next higher whole number.

In this case, the whole number part is 7. Since the fractional part is greater than 1/2, we round the whole number up to the next higher whole number, which is 8.

Therefore, rounding 7 4/5 to the nearest whole number gives us 8.

In summary, when rounding a mixed number to the nearest whole number, we look at the fractional part. If it is greater than or equal to 1/2, we round the whole number up. If it is less than 1/2, we round the whole number down. In this case, since 4/5 is greater than 1/2, we round 7 up to 8.
