Answer:
If 60% of a number is 90.
Suppose that the number is N.
60% of that number can be written as:
(60%/|00%)*N = 0.6*N = 90
Now we can solve that for N
0.6*N = 90
N = 90/0.6 = 150.
for the second part, we have that:
% of a number is 180, what is the 150%?
We do not have the first percentage, so i could not really answer this, so lets do it in a general way.
A% of a number N, is equal to 180.
(A%/100%)*N = 180
(A/100)*N = 180
Then:
N = 180*(100/A).
Now we want to compute the 150% of this number, this will be:
(150%/100%)*N
0.15*N = 0.15*180*(100/A). = 0.15*18,000/A = 2,700/A
Where A will depend on the first percentage.

Rain is falling steadily in Seattle, Washington. After 6 hours, 4 inches of rain has fallen. How long will it take for 1 inch of rain to fall?
Answer:
For one inch of rain, it will take 1.5 hours (1:30)
Step-by-step explanation:
6 divided by 4 is 1.5
Answer:
1hr 30min
Step-by-step explanation:
so 6 hours = 4 inches. You can . divide both by 4 to get 1 inch.
1 inch = 1.5 hours.
1.5 hours is 1 hour and 30 min

Kate has an interior decorating business. She charges a base fee of $25 for each visit and $40 per hour for her labor. 1) Write a function rule to represent this situation for, C, the total cost and h number of hours. 2) Identify the domain and range for the situation. 3) Explain if the situation is discrete or continuous. (if there is no explanation, there will be no credit given) PLEASE I NEED FAST ILL GIVE BRAINLIEST
Answer:
1) C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) Continuous
Step-by-step explanation:
1) The given parameters are;
The base fee charged = $25
The amount charged for labor = $40/hour
The total cost for h number of hours is C = $25 + $40 × h
2) The domain for the ≠unction is 0 ≤ h ≤ ∞
The range for the function is 25 ≤ C ≤ ∞
3) The situation is continuous because the different input values of h can be infinite (from o to infinity)
n is an integer.
Write down the values of n such that -8 ≤ 4n < 12
Answer: -2; -1; 0; 1; 2
[tex]-8\leq 4n<12\\\\=> -2\leq n<3[/tex]
because n is an integer => n ∈ {-2; -1; 0; 1; 2}
Step-by-step explanation:
Answer is : n ={-2; -1; 0; 1; 2}
What is number?A number is a mathematical object used to count, measure, and label. The original examples are the natural numbers 1, 2, 3, 4, and so forth. Numbers can be represented in language with number words.
here, we have,
given that,
-8 ≤ 4n < 12
=> -2≤ n <3
because, n is an integer => n ∈ {-2; -1; 0; 1; 2}
Hence, Answer is : n ={-2; -1; 0; 1; 2}.

Write the equation in slope-intercept form and then graph the equation that passes through (3, 2) and is parallel to the x-axis
Answer:
y = 2
Step-by-step explanation:
The line is parallel to x-axis so its slope = 0
in y = mx + b:
m = 0
b is the y intercept so b = 2 ( from the graph)
y = 0×x + 2
y = 2

Sin = opposite/hypotenuse
Cosine = adjacent/hypotenuse
Tangent = opposite/adjacent
#1
We have to find cos(x) = adjacent/hypotenuse
[tex]cos(x) = adj/hyp\\=\frac{24}{26} = \frac{12}{13}[/tex]
#2:
We are given an angle of 30 degrees and an opposite side of 15
We need to find the adjacent side, so we can use Tangent
[tex]tan(30) = \frac{15}{adj}[/tex]
[tex]adj = \frac{15}{tan(30)} = 25.98 = 26[/tex]
#3
We are given an angle and an opposite side and we have to solve for hypotenuse.
We can use sin
[tex]sin(43) = \frac{16}{x} \\x = \frac{16}{sin(43)} = 23.46 = 23.5[/tex]
#4:
We are given two sides, we have to find the angle. We are given an opposite side and an adjacent side, so we can use arctangent ([tex]tan^-1(x)[/tex], but not 1/tan(x))
[tex]tan(x) = \frac{36}{19} \\arctan(36/19) = x\\x = 62.1759[/tex]
#5
We are given an opposite side and the hypotenuse, we can use sin
[tex]sin(x) = \frac{19}{28}\\x = arcsin(19/28) = 42.73 = 43[/tex]
Why is
f(x) = x²
not a linear function?
Answer:
below
Step-by-step explanation:
f(x) = x² is not linear because it is not a straight line and does not have a constant slope.
The function shows an example of a quadractic function.

the length of a rectangle is 5 more than twice the width. if the perimeter of the rectangle is 76 meters, find the dimensions of the rectangle and choose the equation that represents the perimeter:
1. 76=2w+5
2. 76=2w+2(2w+5)
3. 76=w+2w+5
4. 76=2w+(2w+5)
Answer:
Dimensions: 11 meters by 27 meters
2. [tex]76=2w+2(2w+5)[/tex]
Step-by-step explanation:
Finding Dimensions:
The perimeter of a rectangle can be written as [tex]2l+2w[/tex] where [tex]l[/tex] is the length and [tex]w[/tex] is the width. It is given that the length is 5 more than twice the length of width and the perimeter of the rectangle is 76 meters.
With this information we can write:
Length = [tex]2w+5[/tex]
[tex]2(2w+5)+2w = 76[/tex] (perimeter of the rectangle)
[tex]4w+10+2w=76[/tex]
[tex]6w=66[/tex]
[tex]w=11[/tex]
Length = [tex]2(11)+5[/tex]
Length = [tex]27[/tex]
∴ The dimensions of the rectangle is 11 meters by 27 meters.
Perimeter
Since the length can be written as [tex]2w+5[/tex], the equation that represents the perimeter of the rectangle is [tex]76=2w+2(2w+5)[/tex]

please help me solve one of the ones with a red arrow ! i'm not sure how to do it so if you could show me how you did it it'll help ! ill give brainliest, thanks and points
Answer:
1.)13x = +9
2.)9x = -5
so first you take 1^2 power and it would be 1 so then u add the 1x on to the 12x or 8x from whatever equation ur working on and u would get 13 x or 9x from there u need to get the x isolated from the number without an x so if ur doing number 1 you would do +9 on both sides which would clear the -9 on the left side and add 9 on the right making it 13x = 9
Can you help me solve x it would help me a lot thanks

$0.32 per cup
If two sides and the angle that is not between them of one triangle are congruent to the corresponding two sides and the angle that is not between them of another triangle, then the congruency of those triangles cannot be determined.
Answer:
True
Step-by-step explanation:
The given parameters are;
Two triangles each with known measures of two sides of the triangle and a non included angle
Therefore, with the given information, each of the the triangles are undefined because the sides can be opened wider or narrowed to have two possible solutions, in the same manner a compass, having one leg at a fixed inclination to the drawing paper can have the second leg either come closer or go further than 90 degrees while the inclination of the one (first) leg remains the same.
