Answer: This question does not make sense since 2 minus 4 is -2 and 7 > -2, which means this inequality is true by itself. There are no "solutions" to this inequality since there are no variables. Maybe you made a typo?
Edit: I found the actual question on the internet (it's 7 > z - 4) and the answers are 6, 7, and 10.
This is because simplifying this inequality gives us 11 > z, and 6, 7, and 10 are the only values that are below 11.
Answer:
7 > z - 4

Write the ratio 27 feet to 24 yards as a fraction in simplest form. (Hint: 3 feet = 1 yard.)
Answer:
9/8
27 divided by 3 = 9
24 divided by 3 = 8
I hope this helps!
The ratio in the simplest form of 27 to 24 is equal to 9:8 or 9/8.
What is ratio?When comparing two or more numbers, the phrase ratio is used in mathematics. When one quantity is related to another, it can be used to show how big or tiny it is. Division is used to compare two quantities in a ratio. The term "antecedent" in this context refers to the dividend, and "resultant" to the divisor.
From the given information in the question,
To find the simplest form, divide numerator and denominator with the same number.
Numerator = 27 feet
In simple form = 27/3 = 9
Denominator = 24 yards = 72 feet
In simple form = 72/3 = 24
= 9/24
= 3/8 is the simplest form.

here a subtraction problem that has been solved correctly for 68-59=9 but the choices is 9+68=77 68+9=77 9+59=68 which one is the addition sentence that checks the subtraction problem
Answer:
It's probably 9+59=68
Step-by-step explanation:
=> 9+59=68
68 - 59 gives you 9
So in order to check if the problem was solved correctly you will add the answer plus the subtraction of one number in the two numbers of subtraction
which means between the options 9 + 59 equals to 68 is absolutely the correct answer
Caden exercises daily by walking on a treadmill. He sets the machine so that he will walk at a steady rate of 3.6 miles per hour.
a. If t represents time in hours and d represents distance in miles, write an equation that models the relationship between these variables.
b. Use your equation to calculate the distance Caden will walk in 3/4 of an hour.
c. Use your equation to calculate how long it will take for Caden to walk 4.32 miles.
Answer: For this question, the answers are as follows:
a) d = 3.6t
b) 10.8 miles
c) 1.2 hours
Step-by-step explanation:
Part A: The slope of a line is y=mx+b
equation for this part would be : d=mt
plug in the value: d=3.6t
Part B: The value of t is 3 hours
Plug everything in: 3.6 (3)= 10.8 miles
Part C: The Distance given is 4.32 miles.
4.32 miles = 3.6 hours
then divide both sides by 3.6
you get t=1.2 hours

[tex] \tiny\int_{e}^{{e}^{2}} \left( \sqrt{x + \frac{1}{2} \sqrt{x + \frac{1}{4} \sqrt{x + \frac{1}{8} \sqrt{x + \frac{1}{16} \dots} } } } \: + \sqrt{x - \frac{1}{2} \sqrt{x - \frac{1}{4} \sqrt{x - \frac{1}{8} \sqrt{x - \frac{1}{16} \dots} } } } \right) dx \\ [/tex]
We have the identity
[tex]\left(\sqrt x + \dfrac1{2^n}\right)^2 = x + \dfrac1{2^{n-1}} \sqrt x + \dfrac1{2^{2n}}[/tex]
Take the square root of both sides and rearrange terms on the right to get
[tex]\sqrt x + \dfrac1{2^n} = \sqrt{x + \dfrac1{2^{n-1}} \left(\sqrt{x} + \dfrac1{2^{n+1}}\right)}[/tex]
Decrementing n gives
[tex]\sqrt x + \dfrac1{2^{n-1}} = \sqrt{x + \dfrac1{2^{n-2}} \left(\sqrt{x} + \dfrac1{2^{n}}\right)}[/tex]
and substituting the previous expression into this, we have
[tex]\sqrt x + \dfrac1{2^{n-1}} = \sqrt{x + \dfrac1{2^{n-2}} \sqrt{x + \dfrac1{2^{n-1}} \left(\sqrt x + \dfrac1{2^{n+1}}\right) } }[/tex]
Continuing in this fashion, after k steps we would have
[tex]\sqrt x + \dfrac1{2^{n-k}} = \sqrt{x + \dfrac1{2^{n-(k+1)}} \sqrt{x + \dfrac1{2^{n-k}} \sqrt{x + \dfrac1{2^{n-(k-1)}} \sqrt{\cdots \dfrac1{2^{n-1}} \left(\sqrt x + \dfrac1{2^{n+1}}\right)}}}}[/tex]
After a total of n - 2 steps, we arrive at
[tex]\sqrt x + \dfrac14 = \sqrt{x + \dfrac12 \sqrt{x + \dfrac1{2^2} \sqrt{x + \dfrac1{2^3} \sqrt{\cdots \dfrac1{2^{n-1}} \left(\sqrt x + \dfrac1{2^{n+1}}\right)}}}}[/tex]
Then as n goes to infinity, the first nested radical converges to √x + 1/4. Similar reasoning can be used to show the other nested radical converges to √x - 1/4. Then the integral reduces to
[tex]\displaystyle \int_e^{e^2} \left(\sqrt x - \frac14\right) + \left(\sqrt x + \frac14\right) \, dx = 2 \int_e^{e^2} \sqrt x \, dx = \boxed{\frac43 \left(e^3 - e^{\frac32}\right)}[/tex]

(x+7)(x^2 - 7x + 7^2) = 0 .... sum of cubes factoring rule
(x+7)(x^2 - 7x + 49) = 0
Set each piece equal to zero and solve for x.
You should find that the first piece x+7 = 0 leads to x = -7 as the only real root.
The other piece x^2-7x+49 = 0 leads to two non-real roots, ie complex roots.
If the expression 400(1.12)y gives the number of fish in a man-made lake y years after fish were placed in the lake, which statement is true?
The expression 400(1.12)^y is an exponential function
The true statement is that the growth rate of the fish in the lake is 12%
How to determine the true statement?The expression is given as:
400(1.12)^y
The above expression is an exponential growth function,
Where:
4000 represents the initial value1.12 represents the growth factorNext, we calculate the growth rate (r) as follows:
r = 1.12 - 1
r = 0,12
Express as percentage
r = 12%
Hence, the true statement is that the growth rate of the fish in the lake is 12%

The manager of a grocery store wants to determine what proportion of people who enter
his store are his regular customers. What size sample should he take so that at 95%
confidence the margin of error will not be more than 0.1?
answer:
74
Step-by-step explanation:
The sample size for the given confidence interval is 96.
What is a confidence interval?A range of estimates for an unknown parameter is called a confidence interval (CI). A confidence level calculates a confidence interval; The most common confidence level is 95 percent. The confidence level is the percentage of corresponding CIs that contains the actual value of the parameter over time.
Given confidence of margin is at 95%
E = 0.1 = margin of error
95% confidence interval of Z = 1.96
sample size = n, which is given by
n = (Z/E)²(p)(1 - p)
n = (1.96/0.1)²(0.5)(0.5)
n = 96.04 = 96 approx
Hence, the sample size is 96.

Answer:
A soda costed $3.50.
Step-by-step explanation:
Step 1) We know that a slice of pizza and a soda costs $9 (from Kate's order). With a burger added (Billy's order) it would cost $13.50.
So a burger would cost $4.50:
[tex]13.50-9=4.50[/tex]
Step 2) We also know a burger and a soda costs $8. So we subtract the cost of the burger from Louis' order to find the cost of the soda:
[tex]8-4.50=3.50[/tex]
Cost of soda: [tex]\$3.50[/tex]
