Seemas little sister is now 5 years old.if Her age is 2 years more than 1/4 of seemas age, how old is seems
Answer:
12
Step-by-step explanation:
Seema’s little sister is 2 years more than ¼ of Seema’s age, so you should subtract 2 from 5 to find ¼ of Seema’s age. If 3 is ¼ of Seema’s age, all you do is multiply it by 4 to get the original number. 3x4 is 12, so the final answer is that Seema is 12.

You pick a card at random, put it back, and then pick another card at random. 5 6 7 8 What is the probability of picking a prime number and then picking a prime number? Simplify your answer and write it as a fraction or whole number.
In fraction form, the answer is 1/4, which represents the simplified probability of the given event occurring.
To find the probability of picking a prime number and then picking another prime number, we first need to determine the total number of possible outcomes and the number of favorable outcomes.
Given the four numbers: 5, 6, 7, and 8, we can see that there are two prime numbers (5 and 7) and two non-prime numbers (6 and 8).
The total number of possible outcomes is 4 since there are four cards to choose from.
Now, let's consider the favorable outcomes, which are picking a prime number and then picking another prime number.
The probability of picking a prime number on the first draw is 2/4, as there are two prime numbers out of the four total cards.
Since we replace the card before the second draw, the probability of picking a prime number on the second draw is also 2/4.
To find the probability of both events occurring, we multiply the individual probabilities:
(2/4) * (2/4) = 4/16 = 1/4
Therefore, the probability of picking a prime number and then picking another prime number is 1/4.

find the value of x and the measure of angle axc
Answer:
x = 4
m<AXC = 150
Step-by-step explanation:
m<1 + m<2 = m<AXC
102 + 10x + 8 = 6(6x + 1)
10x + 110 = 36x + 6
26x = 104

what is the value of q³?!
Answer:
-6
Step-by-step explanation:
You seem to want the value of q₃ in the matrix Q⁻¹.
Matrix inverseThe inverse matrix, Q⁻¹, is the transpose of the cofactor matrix, divided by the determinant. That makes q₃ = -q₂₁/det(Q):
q₃ = -(-2/3)/((-1(-1/9) -(-2/3)(-1/3))
q₃ = (2/3)/(1/9 -2/9) = (6/9)/(-1/9)
q₃ = -6

Additional comment
The transpose of the cofactor matrix of a 2×2 matrix is the original with the diagonal terms swapped, and the off-diagonal terms negated. Basically, the only math involved in computing the inverse is finding the determinant, and dividing by it.

From the information provided, the domain and range of this function g(x) in interval notation is given by:
Domain = [-20, 5]Range = [-5, 45]How to determine the true statement?Function g(0) = 2 is false because it was stated that g(0) = -2. Also, g(-4) = -11 is outside the scope of the given range for this function.
Furthermore, function g(7) = -1 is not within the domain for the given function. However, g(-13) = 20 is within the domain for the given function and produces an output that is within the scope of the given range for this function.

O22.5°
30.0⁰
45.0°
67.5°
The measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.
To find the measure of angle ADM, we need to consider that angle ADM is an inscribed angle and its measure is half the measure of the intercepted arc AD.
Given that the measure of arc CD equals the measure of arc DA, it means that these arcs are congruent.
Therefore, the intercepted arcs AD and CD have equal measures.
Since angle ADM is an inscribed angle intercepting arc AD, the measure of angle ADM is half the measure of arc AD.
Therefore, the measure of angle ADM is 45.0°, as the intercepted arc AD is congruent to arc CD.

What are the solutions to logs (x²+8)= 1+logg(x)?
x=-2 and x=-4
x-1 and x=8
x= 1 and x = -8
O x=2 and x=4
Step-by-step explanation:
Log(x²+8)=log 10+ log x
Log(x²+8)=log(10×x)
x²+8=10x
x² - 10x + 8=0
x is approximately to - 1 and - 8✅
The solutions to the given equation are x = -1 and x = 8.
Option A is the correct answer.
What is a solution?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 also find the solution in a system of equations using the substitution or elimination method.
Example:
2x + 4 = 8
The solution is x = 2.
We have,
Using logarithmic properties, we can simplify the given equation:
logs(x² + 8) = 1 + log g(x)
logs(x² + 8) - log g(x) = 1
log[(x² + 8)/g(x)] = 1
(x² + 8)/g(x) = 10
x² + 8 = 10g(x)
Now we can solve for x by substituting the given answer options and solving for g(x):
For x = -2 and x = -4:
x = -2:
(-2)² + 8 = 12, which is not equal to 10 g(x) for any value of g(x).
So x = -2 is not a solution.
x = -4:
(-4)² + 8 = 24, which is also not equal to 10g(x) for any value of g(x).
So x = -4 is not a solution.
For x = -1 and x = 8:
x = -1:
(-1)² + 8 = 9, which is equal to 10g(x) when g(x) = 0.9.
So x = -1 is a solution.
x = 8:
(8)² + 8 = 72, which is equal to 10g(x) when g(x) = 7.2.
So x = 8 is a solution.
For x = 1 and x = -8:
x = 1:
(1)² + 8 = 9, which is equal to 10g(x) when g(x) = 0.9.
So x = 1 is a solution.
x = -8:
(-8)² + 8 = 56, which is not equal to 10g(x) for any value of g(x).
So x = -8 is not a solution.
Therefore,
The solutions to the given equation are x = -1 and x = 8.

You can use any integer—positive, zero, or negative—as an exponent. Expressions with negative exponents are often used to describe very small quantities, such as the diameter of a blood cell. Sizes of microscopic cells are often measured in micrometers, where 1 micrometer is one millionth of a meter, or 10-6 m. Look at these equations that relate expressions with integer exponents. What patterns do you notice in each set?
Set 1:
42 * 45 = 47
42 * 40 = 42
4-2 * 45 = 43
Set 2:
52 * 52 = 54
50 * 54 = 54
5-1 * 5-2 = 5-3
Set 3:
(-2)3 * (-2)4 = (-2)7
(-2)-2 * (-2)1 = (-2)-1
(-2)0 * (-2)3 = (-2)3
In set 1, when we multiply two numbers with the same base, we can add the exponents. In set 2, when we raise a number to a negative exponent, we can rewrite it as the reciprocal of the number raised to the positive exponent. In set 3, when we multiply two negative numbers with the same base, we can add the exponents.
Describe Sets?In mathematics, a set is a well-defined collection of distinct objects or elements, which can be anything such as numbers, letters, people, animals, or even other sets. The objects in a set are called its members or elements, and they are listed inside curly brackets {}.
For example, the set of all positive even integers can be written as {2, 4, 6, 8, ...}, while the set of vowels in the English alphabet can be written as {a, e, i, o, u}. It is important to note that the order of elements in a set is not significant and each element can appear only once in a set.
Sets can be described by listing their elements explicitly, or by using set-builder notation, which describes the set in terms of a property that its members satisfy. For example, the set of all integers greater than 5 can be written as {n | n > 5}, which means "the set of all n such that n is greater than 5."
In Set 1, we notice that when we multiply two numbers with the same base, we can add the exponents. When we divide two numbers with the same base, we can subtract the exponents. We also notice that any number to the power of 0 is equal to 1.
In Set 2, we notice that when we raise a number to a negative exponent, we can rewrite it as the reciprocal of the number raised to the positive exponent. When we multiply two numbers with the same base, we can add the exponents. When we divide two numbers with the same base, we can subtract the exponents.
In Set 3, we notice that when we multiply two negative numbers with the same base, we can add the exponents. When we divide two negative numbers with the same base, we can subtract the exponents. We also notice that any negative number to an even power is positive, and any negative number to an odd power is negative. Finally, we notice that any number to the power of 0 is equal to 1.
