Nicole is running for school president. Her best friend designed a campaign poster, which measured 3 feet by 2 feet. Nicole like the poster so much, she reproduced the artwork on rectangular buttons that measured 2 inches by 1 1/3. What is the scale factor?
Answers
Answer:
The scale factor is 18 to 1 for the painting
Step-by-step explanation:
Here we want to get the scale factor of the original to what is reproduced
Let us have same units first
Mathematically;
1 foot = 12 inches
3 feet = 36 inches
2 feet = 24 inches
So 36 to 2 and 24 to 1 1/3
That will be ratio 36/2 = 18 to 1
same as 25 divided by 1 1/3 = 18 to 1
Express z 1 = 17 [ cos ( π ) + i sin ( π ) ] z 1 =17[cos(π)+isin(π)]z, start subscript, 1, end subscript, equals, 17, open bracket, cosine, left parenthesis, pi, right parenthesis, plus, i, sine, left parenthesis, pi, right parenthesis, close bracket in rectangular form. Express your answer in exact terms.
Answers
Answer:
z1 = -17 + 0i
Step-by-step explanation:
Given the complex number z1 =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;
Since cos(π) = -1 and sin(π) = 0, the equation becomes;
z1 =17[cos(π)+isin(π)]
z1 =17[(-1)+i(0)]
z1 = 17(-1 + 0i)
z1 = -17 + 0i
Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

The measurement of the “ridge” of your new house on blueprints is 24 inches. If the scale is 1/4 = 1ft how long is the wall in real life
Answers
Answer:
In real the wall will be: 96 ft
Step-by-step explanation:
Given that the scale is
1/4 = 1ftIt means 1 inch will represent 4 ft.
so
1 inch = 4ft
Given that the measurement of the “ridge” of your new house on blueprints is 24 inches.
Thus,
24 inches = 24 × 4ft ∵ 1 inch = 4ft
= 96 ft
Therefore, in real the wall will be: 96 ft

Klara picks a number. She rounds to the nearest hundred. She rounds tot the nearest thousand. She rounds the number to the nearest ten thousand. All three times, the result is the same. Which choice could be klara's number?
Answers
Answer with step-by-step explanation:
The question does not seem complete, but I'll try to make some explanations.
When you want to round a number, there are some rules.
1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.
2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.
Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.
Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value
Let's assume she picked: 70 000
Rounding that number to nearest 100, 1000 and 10000 gives the same number which is
70 000.

Can anyone show me how to solve this problem? I know that its 5 weeks. (The problem is “Ahmed is saving his money to buy a Ipad that costs $319.50. Right now he has $21.95, and can save $63.00 each week. How many weeks will it take for Ahmed to have enough money to buy the Ipad)
Answers
Answer:
5 weeks
Step-by-step explanation:
Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.

If we take 1 cup of Original purple paint,
Ratio of blue and red paint = 2 : 3
Quantity of blue paint in 1 cup of the mixture = [tex]\frac{2\times (1)}{(2+3)}[/tex] = 0.4 cups
Similarly, ratio of blue and red paint in the New purple paint = 5 : 7
If we take 1 cup of New purple paint,
Amount of blue paint in 1 cup = [tex]\frac{5\times 1}{(5+7)}[/tex] = 0.42 cups
Therefore, shade of both the mixtures will not be same.
Since, blue color is more in quantity in New purple paint, it will be more blue than Original purple paint.

Solve for the variable x.
4(x - 11) = -210
Answers
Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer: x = -41.5
Step-by-step explanation:
Distribute the 4 that is outside of the parentheses.
4 times x = 4x
4 times -11 = -44
Then to isolate the variable add 44 to both sides of the equation to cancel out -44.
-44 + 44 = 0
-210 + 44 = -166
Now your equation should 4x = -166
To find x, divide both sides of the equation by 4.
4x divded by 4 is x.
-166 divded by 4 is -41.5.
So the answer is x = -41.5.
To check the answer, plug in -41.5 to the x.
4(-41.5 - 11) = -210
