Answer:
29.30%
Step-by-step explanation:
Total Monthly earnings of Jose = $3680
22% is paid for federal and state income taxes and other deductions.
Take-home salary for Jose is total earnings minus the taxes and deductions.
Take-home salary = $3680 - 22% of $3680
Take-home salary = $3680 - $809.6 = $2870.4
Money spent on rent = $755
Money spent on clothing = $86.12
Money spent on rent and clothing combined = $841.12
Percentage of a quantity is given as the quantity divided by the total quantity multiplied with 100.
Therefore,
Percentage of take-home pay spent on rent and clothing:
[tex]\dfrac{841.12}{2870.4}\times 100 = \bold{29.30\%}[/tex]
Ronald said that (8.0 × 107) + (6.2 × 103) = 14.2 x 1010. Amy added the numbers too and said the sum was 8.00062 × 107. Ronald then added the numbers a second time and came up with his original result. Whose solution is correct? Ronald is correct because 80,000,000 + 6,200 = 142,000,000,000.
Yes No B
Amy is correct because adding the decimals and then adding the exponents is not the correct procedure for adding numbers in scientific notation.
Yes No C
Amy is correct because 6.2 × 103 is a much smaller number than 8.0 × 107, so the sum of the two numbers cannot be as large as a decimal times 1010.
Yes No D
Ronald is correct because when you add the exponents in 107 and 103, you get 1010.

express 20cm as a percentage of 3m.
give your answer as a mixed number
Answer:
[tex]6\frac{2}{3}[/tex] %
Step-by-step explanation:
First, convert 3 meters into centimeters.
1m = 100cm
3m = 100 × 3 = 300cm
Now, form the fraction by putting the given value, 20cm, over the total measurement, 300cm.
[tex]\frac{20}{300}[/tex] = [tex]\frac{2}{30}[/tex] = [tex]\frac{1}{15}[/tex] ⇒ Simplify your fraction to its simplest terms.
Next, multiply your simplified fraction by 100 to get your percentage.
[tex]\frac{1}{15}[/tex] × [tex]100[/tex] = [tex]\frac{100}{15}[/tex] = [tex]6\frac{10}{15}[/tex] = [tex]6\frac{2}{3}[/tex] % ⇒ Simplify your percentage to its simplest terms.
Hope this helped! I would really appreciate it if you would please mark me brainliest!
20cm as a percentage of 3m as a mixed fraction is 6 2/3 %
let's convert centimetre to metre
1 cm = 0.01 m
20 cm = ?
cross multiply
length in metre = 20 × 0.01 = 0.2 m
Therefore,
0.2 m as a percentage of 3m is as follows:
0.2 / 3 × 100 = 20 / 3 = 6 2 / 3 %

A cellphone store has 120 cell phones in stock. Of these, 45 have keyboards. The manager of the store wants to add more cell phones with keyboards so that 40% of the stock has keyboards.
Answer:
5
Step-by-step explanation:
Let x be the number of cell phones with keyboards needed.
40% = [tex]\frac{40}{100}[/tex]
[tex]\frac{x+45}{x+120}[/tex] = [tex]\frac{40}{100}[/tex]
x+45 = 40 -----1
x+120 = 100 -----2
You would want to make the total of 1 the same as 2.
1×[tex]\frac{100}{40}[/tex]: 2.5+112.5 = 100 -----3
Now 2 and 3 are equal.
x+120 = 2.5x+112.5
Isolate the x and numbers.
120-112.5 = 2.5x-x
Simplify.
1.5x = 7.5
x = [tex]\frac{1}{1.5}[/tex] × 7.5
x = 5

4(2x - 1) = 3x + 6 Solve for x. Show steps with sentences supporting each step.
Answer:
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
Simplify
8x - 4 = 3x + 6
Subtract 3x from both sides
8x - 3x - 4 = 3x - 3x + 6
5x - 4 = 6
Add 4 to both sides
5x - 4 + 4 = 6 + 4
5x = 10
Divide both sides by 5
5x/5 = 10/5
x = 2
Step-by-step explanation:
4(2x - 1) = 3x + 6
8x-4=3x+6
8x-3x=6+4
5x=10
x=10/5=2

Which graph represents the polynomial function h(x) = x3 + 2x2 – 11x – 12?
y
Answer:
I attached a pic of the answer. I just did the quiz. Hope this helps!!!
Step-by-step explanation:
The graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.
Given that,
To determine the graph of the polynomial function h(x) = x³ + 2x² - 11x -12.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graph of the function h(x) = x³ + 2x² - 11x -12 can be drawn as the function is a polynomial of degree 3 so it will follow two ups and down,
So the graph can be drawn as shown in the image.
Thus, the graph of the polynomial function h(x) = x³ + 2x² - 11x -12 has been shown.

Which of the following inequalities has a solution x≥−3
3(x−1)≤4x
x≥x+32
x6≤x2−1
x+4≥x3
Answer: A
Step-by-step explanation: 3(x-1) becomes 3x -3 ≤ 4x. Put all like variables on the same side, meaning you'll subtract 3x from both sides giving you -3 ≤ x. You can flip the equation around to make it look exactly like x ≥ -3
The inequality 3(x−1)≤4x is showing the solution x ≥−3. The correct option is A.
What is inequality?inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
The inequality 3(x-1) ≤ 4x will be solved as below:-

Answer:
j=3+25, here's the equation
Step-by-step explanation:
J=28
Answer:
j = 28
Step-by-step explanation:
Since we know that j is 25 more than 3, then we must know that 3+25= J (because J is 25 more/+ than 3) So, we simply solve 25+3 which equals 28.

If ZMK APY, m M = 112 ° , m Y = 41 ° , m K = (13x 37) ° , and m A = (2y + 7) ° , find the values of x and y.
need a answer asap
Answer
13x-37=112
13x =149
X=11.4
2y+7=41
Y=24
The value of x and y respectively will be 13° and 17°.
Based on the equation that's given in the question, the value of x will be found thus:
13x - 37 = 112
Collect like terms
13x = 112 + 37
13x = 149
x = 149/13
x = 13
Also, note that 2y + 7 = 41, therefore, the value of y will be:
2y = 41 - 7
2y = 34
y = 34/2 = 17°
Therefore, the value of x and y respectively will be 13° and 17°.
