Please help I have trouble on these...
The value of a is 5, b is 4, c is 0, d is 3, e is 6 and R is 6 after following the long division method.
According to the question,
We have to divide 430 by 8 by following the long division method.
Note that when we follow long division method then the number by which we are dividing (divisor) is to be multiplied in such a way that the result remains less than the number in the dividend.
Now, we will solve it step by step.
In dividing 43 by 8, we have to multiply 8 by 5. Then, we get 40.
So, we have a = 5, b = 4 and c = 0.
Now, after this we have 30 and the number that we get after multiplication is 24. So, 3 has to be multiplied in 8 to get 24.
So, we have d = 3.
Now, when we will subtract 24 from 30, we will get 6.
So, we have e = 6.
And e is also the remainder, R. So, we have R = 6.
Hence, the values of a, b, c, d, e, and R are 5, 4, 0, 3, 6, and 6 respectively.

Using log evaluate 3^x=10
Answer:
x ≈ 2.09590327429
Step-by-step explanation:
You want the solution to 3^x = 10 using logarithms.
LogsTaking logarithms of both sides of the given equation, we have ...
x·log(3) = log(10)
Dividing by the coefficient of x gives ...
x = log(10)/log(3)
x ≈ 2.09590327429
__
Additional comment
If the logarithm to the base 10 is used, then this becomes ...
x = 1/log₁₀(3)
The meaning of "log( )" varies with the context. In high-school algebra, it usually means "log₁₀( )". In other contexts, it may mean "ln( )", the natural logarithm.
For the purpose here, it doesn't matter what base the logarithms have, as long as log(10) and log(3) are to the same base.
<95141404393>
The approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.
To evaluate the equation 3^x = 10 using logarithms, we can take the logarithm of both sides of the equation. The most commonly used logarithm is the base 10 logarithm, also known as the common logarithm (log).
Taking the log of both sides, we get:
log(3^x) = log(10)
Now, we can apply the logarithmic property that states log(a^b) = b * log(a). Applying this property to the left side of the equation:
x * log(3) = log(10)
Next, we can divide both sides of the equation by log(3) to isolate the variable x:
x = log(10) / log(3)
Using a calculator, we can evaluate the right side of the equation:
x ≈ 1.46497
Therefore, the approximate value of x that satisfies the equation 3^x = 10 is approximately 1.46497.

Determine when a simple 2x2 system of linear equations has no solutions.
If m = -5 or m = 3, the system of linear equations has no solution.
To determine the values of m for which the system of linear equations has no solution, we need to check the determinant of the coefficient matrix, which is:
| 3 m |
| m+2 5 |
The determinant is
= (3 x 5) - (m x (m+2))
= 15 - m^2 - 2m
= -(m^2 + 2m - 15)
= -(m+5)(m-3)
So, for the system to have no solution, the determinant must be zero, so we have:
-(m+5)(m-3) = 0
This gives us two values of m: m = -5 and m = 3.
Thus, if m = -5 or m = 3, the system of linear equations has no solution.

Answer:

Step-by-step explanation:
formula - πr^2\(\frac{h}{3}\)
3 x 3 x 3.14 = 28.26
28.26 x 9/3
28.26 x 3
answer = 84.78
Answer:
84.78 inches cubed
Step-by-step explanation:
You need to comprehend the volume formula for cones
Volume Formula for Cones: V=1/3hπr²
Your measurements:
9 inches for height
3 inches for radius
**Radius is half of a circle and diameter is full of the circle/base.***
Equation:V=1/3 x 9in x π x 3²
You should do 3 squared first so that you can input it into your calculator easily.
V=1/3 x 9in x π x 9
Now on a calculator do 1 divided by 3 which is the "1/3" in the formula.
Then multiply 9, 3.14 for pi, and 9 for radius.
Note: You should do 3.14 for pi not the whole pi symbol on the calculator.
Your answer: 84.78 in cubed

Compute the missing x and y values so that each ordered pair will satisfy the given equation y=2x+4
The missing ordered pairs that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).
The equation given is y = 2x + 4. To compute the missing x and y values, we need to substitute the given ordered pairs into the equation and solve for the missing variable.
Let's assume we have an ordered pair (x, y) that satisfies the equation y = 2x + 4.
For example, let's say one missing value is x = 3. We can substitute this into the equation:
y = 2(3) + 4
y = 6 + 4
y = 10
So, the missing ordered pair is (3, 10).
Similarly, if another missing value is y = 8, we can substitute this into the equation and solve for x:
8 = 2x + 4
4 = 2x
x = 2
So, the missing ordered pair is (2, 8).
In summary, the missing x and y values that satisfy the equation y = 2x + 4 are (3, 10) and (2, 8).

Determine the smallest integer value of x in the solution of the following inequality.
-3x+10≤5
Answer: The smallest integer value of x in the solution is 1.
Step-by-step explanation:
The given inequality: \(-3x+10\leq5\)
To solve the inequality, we first subtract 10 from both sides
\(-3x+10-10\leq5-10\\\\\Rightarrow\ -3x\leq-5\)
Multiply negative sign on both sides ,we get
\(3x\geq5\)
Divide both sides by 3, we get
\(x\geq\frac{5}{3}\)
i.e. \(x\geq 1.6666666667\\\)
\(x\geq1\)
Hence, the smallest integer value of x in the solution is 1.
Fill in the blank using the scaling factor that makes the number sentence true. 5.3 × > 5.3 0.886 or 1.00 or 1.003
The given options, the only value greater than 1 is 1.003. Therefore 0.886, which is less than 1 and makes the inequality true.
The given number sentence is 5.3 × > 5.3, where we need to find the scaling factor that makes the inequality true. To do this, we can divide both sides of the inequality by 5.3. This gives us:
5.3 × x > 5.3 ÷ 5.3 × k
We need to find the value of k that makes the inequality true. Simplifying the right-hand side of the equation, we get:
5.3 ÷ 5.3 × k = k × 1 = k
Substituting this into our equation, we get:
5.3 × x > k
We know that 5.3 × 1 = 5.3, which means that k must be greater than 1 to satisfy the inequality. Among the given options, the only value greater than 1 is 1.003. However, this value would make the inequality too large, so it is not the correct answer.
The correct answer is therefore 0.886, which is less than 1 and makes the inequality true.

11.) 117+100+105+115+x=540

Answer:
10.) 102 11.) 103 12.) 145
Step-by-step explanation:
I am assuming you need help on all three questions.
10.) This shape, a trapezoid, has 4 angles. Therefore these angles are going to all add up to 360 degrees.
To solve... 360 - 120 - 85 - 53 = 102
OR...
120 + 85 + 53 = 258 then... 360 - 258 = 102
11.)This shape, a pentagon, has 5 angles. Therefore these angles are going to all add up to 540 degrees.
To solve... 540 - 117 - 100 - 105 - 115 = 103
OR...
117 + 100 + 105 + 115 = 437 then 540 - 437 = 103
12.)This shape, a heptagon, has 7 angles. Therefore these angles are going to all add up to 900 degrees.
To solve... 900 - 116 - 120 - 129 - 130 - 135 - 125 = 145
OR...

Joaquin wants to make his famous chocolate chip cookies to bring to his friend's birthday party. The original recipe serves 8 people and requires 1/2 of a cup of butter but he
needs it to serve 28 people. How many cups of butter will he need?
Answer: He will need 1 1/4 cups of butter
Step-by-step explanation:
1. We can do 28/8 to find how much we need to multiply our 1/2 cup of butter to keep the ratio of people to cups of butter the same. 28/8= 3 1/2
2. Then we can multiply 3 1/2 and 1/2 to get 1 1/4 cups of butter.
Joaquin requires 5.25 cups of butter to serve 28 people.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
Given that the original recipe serves 8 people and requires 1/2 of a cup of butter but he needs it to serve 28 people.
Let the quantity of butter required for the new recipe be x.
To determine how much to multiply our 1/2 cup of butter in order to keep the same proportion of persons to cups of butter,
we can use the ratio of 28/8.
So, 8:1.5::28:x
⇒ 8x = 42
⇒ x = 5.25
Hence, Joaquin requires 5.25 cups of butter to serve 28 people.

Step-by-step explanation:
The meaning in the situation is B; positive correlation; as time passes, the CPI increases.
What does correlation coefficient convey?The correlation coefficient is the degree of association between two quantities in terms of linear relation. The range of correlation coefficient is -1 to 1
If the correlation is -1, then that refers as the one quantity increases, the other quantity decreases , also the correlation is 0, then there is no linear relationship between two variables.
There are two types of Correlation;
Positive Correlation= With Increase in x value, y value also increases, we call it positive correlation.
Negative Correlation= With Increase in x value, if y value decreases, we call it negative correlation.
As we can see from the points plotted on the graph ,with increase in x value , y value decreases.
Hence, positive correlation; as time passes, the CPI increases.
