Answer:
10/4 equals 2 1/2 when simplified.
Step-by-step explanation:
10/4 = 2 2/4 or 2 1/2 when simplified.
This is because, 4 x 2 = 8, and 8 + 2 (or 1/2 of 4) = 10.

(x + 4)(x − 12) = 0 can someone help me with this
Answer:
You chose the correct option on the picture
x = -4; x = 12
Step-by-step explanation:
You solve for x by simplifying both sides of the equation, then isolating the variable.
If any individual factor on the left side of the equation is equal to 0, the entire expression will be equal to 0.
x + 4 = 0
x − 12 = 0
Set x + 4 equal to 0 and solve for x.
Set x+4 equal to 0.
x+4=0
Subtract 4 from both sides of the equation.
x = −4
Set x − 12 equal to 0 and solve for x.
Set x−12 equal to 0.
x−12=0
Add 12 to both sides of the equation.
x=12
The final solution is all the values that make (x+4)(x−12)=0 true.
x=−4,12

Find the difference: 25 kg 32 g - 23 kg 83 g
The difference of the weight is 1 kg 949 g.
How to find the difference of numbers?The weight of the two items to find the difference are as follows:
25 kg 32 g23 kg 83 gDifference in mathematics is the result of subtracting one number from another.
Therefore, let's convert the weight .
1000g = 1 kg
32 g =
cross multiply
weight = 32 / 1000
weight = 0.032 kg
1000g = 1 kg
83 g = ?
cross multiply
weight = 83 / 1000 = 0.083 kg
Therefore,
25 kg + 0.032 kg = 25.032 kg
23kg + 0.083 kg = 23.083 kg
Hence,
the difference of the weight = 25.032 kg - 23.083 kg
the difference of the weight = 1.949 kg
Hence,
the difference of the weight = 1 kg 949 g

Answer:
Step-by-step explanation:
We will apply the definition of the derivative. Then we use algebra to expand and simplify the numerator. Next, we can cancel a factor of

Is this true? log(x) = logb(c) * log(x). For this question, first try several examples. Then prove it. See the proofs in the Basic Math lecture for ideas. (Hint: let
m = logb(x) and n=logb(c) and p = logc(x). Then use the definition of logarithms and rules of exponents to show m = np.
The logarithmic statement [tex]log_bx=log_bc \cdot log_cx[/tex] is true.
Logarithm is a mathematical operator that is used to simplify the exponential equations .
The logarithm is exponentiation's opposite function in mathematics. This indicates that the base b of another fixed number, the logarithm of a given number x, is the exponent that must be raised in order to obtain the given number x.
The exponential equation logₓy=n is equivalent to xⁿ=y.
The properties of Logarithmic equations are:
log x + log y = log xylog x-log y= log (x/y)log ₙn=1n log x = log xⁿ[tex]log_ab=\frac{log_xa}{log_xb}[/tex] , x≠0Now the given expression is of the form: [tex]log_bx=log_bc \cdot log_cx[/tex]
We know that [tex]log_bc=\frac{log_nc}{log_nb}[/tex] and [tex]log_cx=\frac{log_cx}{log_nc}[/tex]
let n=[tex]log_bc=\frac{log_nc}{log_nb}[/tex] and p=[tex]log_cx=\frac{log_cx}{log_nc}[/tex]
Now for the right side of the equation we have:
n×p
[tex]log_bc \cdot log_cx[/tex]
This can be written as:
[tex]or, \frac{log_nc}{log_nb}\cdot\frac{log_cx}{log_nc}\\or, \frac{log_cx}{log_nb}\\or, log_bx[/tex]

A weather forecaster claimed the chance of rain next week on Monday is 50% and the chance it rains on Tuesday is 80%. Is the probability that it rains next
Monday and Tuesday equal to 40%?
O Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.
O No, because the chance of rain on Monday and the chance of rain on Tuesday are not independent.
O No, because the chance of rain Monday and the chance of rain Tuesday are not mutually exclusive.
O Yes, because the chance of rain on Monday and the chance of rain on Tuesday are mutually exclusive,
Answer:
A: Yes, because the chance of rain on Monday and the chance of rain on Tuesday are independent.
Step-by-step explanation:
We are given;
chance of rain next week on Monday is 50%. Thus;
P(rain next Monday) = 0.5
chance it rains on Tuesday is 80%. Thus;
P(rain next Tuesday) = 0.8
From independent events, we can say that;
P(A and B) = P(A) × P(B)
A and B are independent events because the probability of A doesn't affect B as is the case for rain on Monday and Tuesday given.
Thus;
P(rain on Monday & tuesday next week) = 0.5 × 0.8 = 0.4
This can also be written as 40%
Correct answer is option A since both events are independent

A florist has to pay $7.50 each time a customer chooses a competitor for the delivery of flowers. Which expression shows the amount that the florist earns if p people use a competitor for delivery, and the company makes $320.00 before any payment is made to their competitors?
320 minus 7.50 p
320 + 7.50 p
7.50 p minus 320
7.50 p + 320
Answer:
320 minus 7.50 p
Explanation:
the florist earned 320 dollars and then lost money due to having a competitor deliver, since we dont know the amount of people who chose competitors we use the term p next to the amount that p is worth because each time a customer uses a competitor it costs 7.50 out of the original 320.

It is found that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Given that the system of a linear equation and a quadratic equation.
2x – y = –1
x² – 5x – y = –7
Now Tommy had completed the following steps in his algebraic solution process but could not factor the resulting quadratic equation as;
x² – 7x – 1,
Step I: y = 2x + 1
Step II: x² – 5x – (2x + 1) = –7
Step III: x² – 5x – 2x – 1 = –7
Step IV: x² – 7x – 1 = –7
Therefore, we conclude that in Step IV; Tommy must set the quadratic equations equal to 0 before factoring and then solving.
