Round your answer, if necessary, to the nearest tenth.
Answer:
47.3 grams
Step-by-step explanation:
Given: A solution contains 4.3 grams of salt per liter.
To find: Amount of salt in 11 liters of the solution
Solution:
Amount of salt in 1 liter of the solution = 4.3 grams
So, amount of salt in 11 liters of the solution = 11 × Amount of salt in 1 liter of the solution = 11 × 4.3 = 47.3 grams
Hence, 11 liters of the solution contains 47.3 grams of salt.
Answer: 47.3

Answer: q = 13
because p and q are inverse
=> 26/10 = q/5
⇔ q = 26/10.5
⇔ q = 13

Answer:
The women's department of a store stocks have more types of white socks.
Step-by-step explanation:
Given:
The women's department of a store stocks 4 types of black socks for every 5 types of white socks.
Ratio of black socks to white socks = 4 : 5
The men's department stocks 6 types of black socks for every 7 types of white socks.
Ratio of black socks to white socks = 6 : 7
Each department has the same number of black socks.
Question asked:
Which department stocks more types of white socks?
Solution:
Let each department has 100 black socks.
For women's department
4 : 5 : : 100 : white socks
For men's department
6 : 7 : : 100 : white socks
We found that out of 100 black socks the women's department of a store stocks have 125 white socks while the men's department stocks have about 117 white socks then by default understood that the women's department of a store stocks have more types of white socks.
Answer:
The women have more

Step-by-step explanation:
The given information tells us that f(x) is a continuous function, and it passes through the points (-2, 10) and (-7, -5). Additionally, it has exactly one value of x for which f(x) = 0. We need to find which of the given options (-3, -8, 0, 2) could be that x value.
Let's analyze each option:
a) -3: If f(-3) = 0, it's a possibility, but we need to check the others.
b) -8: If f(-8) = 0, it's a possibility, but we need to check the others.
c) 0: If f(0) = 0, it's a possibility, but we need to check the others.
d) 2: If f(2) = 0, it's a possibility, but we need to check the others.
Since we are told that there is only one value of x for which f(x) = 0, and there are multiple possibilities in this case (a, b, c, and d), the information provided does not allow us to determine a unique answer from the given options. Any of these values could be the x for which f(x) = 0, given that the function is continuous.
The question uses the concept of Intermediate Value Theorem in mathematics. The answer is option a) -3 as it falls between the range by the theorem, which states that for any continuous function within a certain range, the function must cross all values within that range.
This question is about the Intermediate Value Theorem, which states that if a function is continuous on a closed interval from a to b, and k is any number between f(a) and f(b), then there is at least one number c in the interval (a, b) such that f(c) = k.
Since the function is continuous for all real numbers and f(-2) = 10 and f(-7) = -5, the function must pass through 0 between -2 and -7 as it moves from 10 to -5. Therefore, the x value for which f(x) = 0 could be between -2 and -7. In the provided options, the only value falling within the interval (-2, -7) is -3.
So, based on the Intermediate Value Theorem, the answer is option a) -3.
