Henry wants to buy a coat that has an original price of $125. During an upcoming sale, the price of the coat will be reduced by 4% each week. Henry plans to wait until the price of the coat is less than $100 and uses this inequality to determine w, the number of weeks that he needs to wait to buy the coat: 125(0.96)^w<100 How many weeks must Henry wait for the price of the coat to first fall below $100?
Answers
Answer: The Answer is 6 weeks
Step-by-step explanation:
Because if you go into a calculator and do 125*0.96^ and do a random number after that it will start decreasing and you want to get the lowest number so he can get the coat as soon as he can and I got 6 because 125*0.96^6= 97.8
Look at the table below. What is the mode of the data

Answer:
26
Step-by-step explanation:
To get the inside measure of the line that 109 sits on, you will take the angle of the straight line (180) and substract 109.
180-109 = 71
this is the angle adjacent to 109
All angles in a triangle combined are 180
Substract all known angles and you get your answer
180-71-83 = 26

Given the figure below find the values of x and z
(12x +2)°
94°
z°
Answers
Answer:
z = 94
x = 7
Step-by-step explanation:
The angle with a measure of 94° and the angle labeled "z" are vertical angles
Vertical angles are congruent ( equal to each other )
Which means that because "z"s vertical angle = 94° z also equals 94°
The angle labeled with the expression ( 12x + 2 ) and the angle with a measure of 94° are supplementary angles
Supplementary angles add up to equal 180
Hence, 94 + 12x + 2 = 180
^ (Note that this is the equation we will use to solve for x )
Now we solve for x
94 + 12x + 2 = 180
step 1 combine like terms
94 + 2 = 96
we now have 180 = 96 + 12x
step 2 subtract 96 from each side
180 - 96 = 84
96 - 96 cancels out
we now have 84 = 12x
step 3 divide each side by 12
84 / 12 = 7
12x / 12 = x
we're left with x = 12
Answer:
z = 94
x = 7

A person that is 175 cm tall is standing outside. How long is this person's shadow if the sun is 60 degrees above the ground?
Answers
Answer: 101.03 cm
Step-by-step explanation:
Given
The height of the person is [tex]h=175\ cm[/tex]
Sun is [tex]60^{\circ}[/tex] above the ground
Suppose x is the length of the shadow
From the figure, we can write
[tex]\Rightarrow \tan 60^{\circ}=\dfrac{h}{x}\\\\\Rightarrow x=\dfrac{h}{\tan 60^{\circ}}\\\\\Rightarrow x=101.03\ cm[/tex]
So, the length of the shadow is 101.03 cm

Kade is gathering box tops for his school. Last year he was able to collect 312 box tops. Out of 312 box tops, 24 were already expired. He collected 441 box tops this year. How many boxtops will be expired this year if Kade can estimate the number of box tops that will expire this year using the ratio from last year? Round to the nearest whole number.
Answers
What do you mean by asap
The number of box tops expired this year is 34.
What is the ratio?
The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given that, Last year he was able to collect 312 box tops. Out of 312 box tops, 24 were already expired.
So, the ratio is 312:24
39:3
13:1
He collected 441 box tops this year.
Here, the ratio is 441/13 =34
Therefore, the number of box tops expired this year is 34.

Which of the following are solutions to the equation below?
Check all that apply
4x²+ 12x+ 9 =25
Answers
Answer:
B and C
Step-by-step explanation:
First, we need to get the left side equal to zero. Take away 25 from each side to get [tex]4x^2+12x-16 = 0[/tex].
We can use the quadratic equation of [tex]\frac{-b+ -\sqrt{b^2-4ac} }{2a}[/tex] to find the solutions.
Plug them in to get [tex]\frac{-12+-\sqrt{144 -(-256)} }{8}[/tex].
Simplify.
[tex]\frac{-12+-\sqrt{400} }{8}[/tex]
[tex]\frac{-12+-20}{8}[/tex]
