Answer:
x = √70
Step-by-step explanation:
The triangles shown are all similar, so corresponding sides are proportional.
hypotenuse/long side = x/7 = (7+3)/x
Cross-multiplying gives ...
x^2 = 7(10)
x = √70
_____
You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.
A similar "geometric mean" relation holds for the short side:
BC = √(CD·CA)
There is yet another "geometric mean" relation that holds for the altitude:
BD = √(CD·AD)
You may see these again.
Solution to the systems of equations,
g(x)=3x+2
f(x)=|x-1|+1
Hi there! :)
[tex]\large\boxed{\text{ x = 0, or (0, 2)}}[/tex]
The solution of g(x) = 3x + 2 and f(x) = |x - 1| + 1 is where the two lines intersect.
According to the graph, the functions intersect at the point (0, 2), or x = 0. This is the solution to the system of equations.
We could also prove this algebraically by setting the two equations equal to each other:
3x + 2 = | x - 1 | + 1
Assume the absolute value function is negative:
3x + 2 = -(x - 1) + 1
Simplify:
3x + 2 = -x + 2
Add x to both sides:
4x + 2 = 2
Subtract 2 from both sides:
4x = 0
x = 0. This is the solution to the system.
. Suppose that 10 students of a class of 50 undergraduates are chosen for a behavioral experiment. The total class consists of 15 freshmen, 18 sophomores, 10 juniors, and 7 seniors. If all students are equally likely to be picked, determine the probability of the group contains exactly seven seniors and three juniors.
Answer:
Approximately 0% probability of the group contains exactly seven seniors and three juniors.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, the order in which the students are chosen is not important, which means that we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
Desired outcomes:
7 seniors, from a set of 7.
3 juniors, from a set of 10. So
[tex]D = C_{7,7} \times C_{10,3} = \frac{7!}{7!(7-7)!} \times \frac{10!}{3!(10-3)&} = 1 \times 120 = 120[/tex]
Total outcomes:
10 students froms a set of 50. so
[tex]T = C_{50,10} = \frac{50!}{10!(50-10)!} = 10272278170[/tex]
Probability:
[tex]p = \frac{D}{T} = \frac{120}{10272278170} \approx 0[/tex]
Approximately 0% probability of the group contains exactly seven seniors and three juniors.

John makes a commission of 6% when he sells a house how much is john's commission if he is sells a house for $300,000
Answer:
18,000
Step-by-step explanation:
6% is 0.06
300,000 * 0.06 = 18,000
Answer:
John's commision is $18,000
Step-by-step explanation:
This is is essentially asking what 6% of $300,000 is.
6% in decimal form equals 0.06
You then multiple the decimal to the orginal value.
(0.06)(300,000) = 18,000
John's commision is $18,000

Here are eight angles. Which of these angles are obtuse angles?
Enter your answer as a list of letters, separated by commas. For example, if you believe angles A, B, and F are obtuse, type A, B, F.
Help me please. Please, Please!!!
The obtuse angles from the given list are D (between 90° to 180°) and E (111° angle). Thus, the answer is D, E.
The angles are given as follows:
A: less than 45°
B: greater than 270°
C: right angle
D: between 90° to 180°
E: A 111° angle
F: A 222° angle
G: A 0.180° angle
H: A 180.180° angle
To identify which angles are obtuse, we need to determine the angles that are greater than 90 degrees but less than 180 degrees.
Among the given angles:
A: less than 45° (not obtuse)
B: greater than 270° (not obtuse)
C: right angle (not obtuse)
D: between 90° to 180° (obtuse)
E: 111° angle (obtuse)
F: 222° angle (not obtuse)
G: 0.180° angle (not obtuse)
H: 180.180° angle (not obtuse)
Therefore, the obtuse angles from the given list are:
D (between 90° to 180°)
E (111° angle)
The answer is D, E.

The volume of a cube is 216 ft^3. What is the length of a side?
Answer:
54
Step-by-step explanation:
cause a cub has 4 sides so each side is 54
Answer:
The length of a side is 6.
Step-by-step explanation:
Since, the volume of a cube is equal to l*w*h.
V=l*w*h
Volume is equal to side cubed.
V=s^3
Cube 216 to get 6.
216=s^3
3^√216=s

For a two-day rental at the surf shop, it cost $55 to rent a surf board and $70 to rent a paddle board. On a certain weekend, the surf shop rented 51 total surf boards and paddle boards and made $3300. How many paddle boards were rented?
Answer:
7 paddleboards
Step-by-step explanation:
In order to solve this, you have to find the total amount that they earned by renting surfboards.
To find this you multiply 55 x 51 =2,805.
Then you use this factor and subtract it from the total amount they earned.
$3,300 - $2,805 = $495.
This shows us that they earned a total of $495 from renting out paddle boards. To find out how many paddle boards were rented out you have to divide $495 by $70 which is how much they charge to rent paddle boards.
495/70 = 7
In conclusion, they rented out 7 paddle boards.
