Answer:
3
Step-by-step explanation:
First, you need to turn 12 into 0.12. Then, you multiply that by 25 and boom you get 3.
This is the same every time.
For example, what percent is 28 of 49?
0.28*49=13.72.
Out of 25 students 48% students have blue eyes.
What is percentage?Percentage is the relative value indicating one hundredth part of any quantity.Percentage is denoted by (%).How to find what percent of students have blue eyes?According to the question,
Total number of students in the class = 25Total number of students having blue eyes = 12Now, we can calculate the percentage by the formula, [tex](\frac{number}{total})[/tex] x 100 %
∴ percentage of students have blue eyes [tex](\frac{12}{25})[/tex] x 100 % = 48 %
∴ percentage of students have blue eyes are 48 %

Can someone help me with this question please :) (University)
Answer:
(-5 1 0 0) and (-3 0 1 0)
Step-by-step explanation:
Based on my memory, you can use the dot product to find orthogonality meaning
u1 . u2 = 0
In this case, we let u be the arbitrary vector represented by (x y z w)
u . (1 5 3 0) can be expressed as an equation given by:
{(x y z w) | x + 5y + 3z + 0w= 0}
We solve this equation letting y = s and z = t and x = -5s -3t
Reconstruct this according to their variable will give
(-5 1 0 0)s + (-3 0 1 0)t = 0
So the basis vectors are (-5 1 0 0) and (-3 0 1 0).
Let c1 and c2 be arbitrary constants:
if you solve for c1(-5 1 0 0) + c2(-3 0 1 0) = 0
c1 and c2 should have only trivial solution, which proves its
linear independence and so it forms a basis vector space.

(24.7C) The area of a rectangle is equal to x2 +
16x + 55 square units. If the length of the
rectangle is equal to x + 11 units, what expression
represents its width?
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5

Meg pounded a stake into the ground. When she attached a leash to both the stake and her dog’s collar, the dog could reach 9 feet from the stake in any direction. Using 3.14 for pi, what is the approximate area of the lawn, in square feet, the dog could reach from the stake.
The dog is able to run around in a circle with a radius of9 ft.
The area of a circle is A = pi r^2
A = (3.14) (9)^2
A= (3.14)(81)
A= 254.34 sq ft

geometry: find the value of x. Round to the nearest tenth. How do I do this? screenshot attached
Answer:
[tex]\boxed {\boxed {\sf x \approx 105.3}}[/tex]
Step-by-step explanation:
To solve for x, remember the right triangle trigonometry ratios (soh-cah-toa).
sinθ= opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ= opposite/adjacentIf we look at the angle given (θ), then we see that 36 is adjacent or next to the 70° angle. x is the hypotenuse because it is opposite the right angle. So, we have to use cosine (adjacent and hypotenuse).
[tex]cos (\theta)=\frac {adjacent}{hypotenuse}[/tex]
[tex]cos(70)=\frac{36}{x}[/tex]
Cross multiply. (Multiply the first numerator by the second denominator. Then, multiply the first denominator by the second numerator).
[tex]\frac{cos(70)}{1}=\frac{36}{x}[/tex]
[tex]cos(70)*x= 36[/tex]
Since we want to solve for x, we must isolate the variable. Divide both sides by the cosine of 70.
[tex]\frac{cos(70)*x}{cos(70)}=\frac{ 36}{cos(70)}\\x= 105.2569584[/tex]
Round to the nearest tenth. The 5 in the hundredth place tells us to round the 2 to a 3.
[tex]x \approx 105.3[/tex]
x is about 105.3

Is the following graph exponential? Explain how you know.
Answer:
no
Step-by-step explanation:
the graph provided on the picture is y=x². It is visible, when the value of 'x' isdecreasing, the values of the function 'y' is increasing. If the function provided is exponential, then the values of the function 'y' is decreasing also.

20/48 equals what as a percentage
Answer:
approx 41.6%
Step-by-step explanation:
Answer:
41.7%
Step-by-step explanation:
First, you will divide 20 by 48.
[tex]20/48=0.4167[/tex]
Secondly, you would multiply by 100%
[tex]0.4167* 100= 41.67%[/tex]%
If you round to the nearest whole number it would give you [tex]42[/tex]%. If it is rounded to the nearest tenth it would be [tex]41.7%[/tex]%
I need help please A. The relationship is linear because each Y-value is two more than the value before. B. The relationship is linear because each y-value is two times the value before it. C. The relationship is exponential because each y-value is two more than the value before it. D. The relationship is exponential because each y-value is two times the value before it.
Answer:
D) the relationship is exponential because each y-value is two times the value before
Step-by-step explanation:
A and B are out because this graph is not a linear graph. D is out because that explanation represents a linear graph. An exponential equation will always multiply the value before it, not add.
