Some General Information:
⇒ both triangles are isosceles triangle
⇒because two of the angles are equal to each other
⇒ which means there are two equal sides that always join at the
same angle to the base (the third side), and meet directly above
the midpoint of the base (I attached a diagram for a better
explanation)
Question 11:
⇒ x and 10 are equal
⇒ because their sides join the third side at the base with the same
angle
⇒ so x = 10
Question 12:
⇒ '2x + 23' and 7 are equal
⇒ because their sides join the third side at the base with the same
angle
⇒ so:
[tex]2x+23=7\\2x=-16\\x = -8[/tex]
⇒ thus x = -8
Hope that helps!

Fifteen years ago, Russell bought his house for $141,000. The house’s property value has decreased by 1.6% per year ever since then. If Russell sells his house, how much is it worth, to the nearest hundred dollars?
a.
$110,700
b.
$107,200
c.
$67,100
d.
$37,900
Answers
Answer:
141000 * (1 - 0.016)^15 = 110699.48 = A 110700
Step-by-step explanation:
1st year depreciation = 141000 - (141000 * 0.016) = 138744
2nd year depreciation = 138744 - (138744 * 0.016) = 136524.096
3rd year depreciation = 136524.096 - (136524.096 * 0.016) = 134339.710464
etc. unitl you reach the 15th year
Basically we calculate 1.6% of the current value of the house and subtract that from the current value for each year for 15 years.
The equation used in the answer is a faster way to approach your answer instead of calculating for each year.
You'd multiply your initial value by the difference in percentage (note well that since it is decreasing in value we subtract the decimal equivalent to 1.6% which is 0.016, from 1 where one represents 100% and then raise the difference gained to the power of the amount of years which would be 15.
A swimming pool is shaped like a right rectangle prism. the pool is 36 ft long and 20 ft wide. What is the total amount of water in cubic ft,needed to fill tje pool to a depth 4 ft.
Answers
Answer:
2880 ft³
Step-by-step explanation:
T o find the total amount of water that is needed to fill the pool, you have to find the volume of the pool.
Formula to find the volume of a rectangle prism is :
Volume = length × width × height
Let us solve now.
Volume = length × width × height
Volume = 36 ft × 20 ft × 4 ft
Volume = 2880 ft³
Therefore, 2880 ft³ of water is needed to fill the pool.

plane?
A. 124.75
В. 135.9
C. 127.4
D. 128.5
Answers
Step by step:
Start with 10 flights it gives you
Assuming this data is rhe same for each 10 flights you should divide 45 by 10 to get an average of 4.5. (the amount of sets of 10 planes) You then use this number as a constant multiplying it by the number of planes with the same amount of passengers.(in this case 3 flights with 119 passengers) So that would look like this: 4.5 x 3=13.5 (the number of total flights with 119 passengers) Continue to do this with each number set, add them all up, and divide them by the total number of planes, 45.
IM NOT SURE HOW TO SOLVE THIS CAN SOMEBODY HELP ME
Answers
Answer:
The y-intercept is the point (0, 128).
The x-intercepts are the points (-4, 0) and (-8, 0).
As x → ∞, y → ∞.
As x → -∞, y → -∞.
Step-by-step explanation:
To find the y-intercept, substitute 0 for x and solve for y.
P(x) = (x + 4)²(x + 8) P(0) = (0 + 4)²(0 + 8)P(0) = (4)²(8)P(0) = 16 * 8 P(0) = 128The y-intercept is (0, 128).
To find the x-intercept, substitute 0 for y and solve for x.
0 = (x + 4)²(x + 8)Set the first term, (x + 4)², equal to 0.
0 = (x + 4)²0 = x + 4 -4 = xx = -4Set the second term, (x + 8), equal to 0.
0 = x + 8 -8 = xx = -8The x-intercepts are the point (-4, 0) and (-8, 0).
Look at the degree and leading coefficient of the polynomial to determine the end behavior, and therefore you can determine how y behaves as x gets closer to infinity.
Since the degree of the polynomial is odd (3) and the leading coefficient is positive, the graph falls to the left and rises to the right.
So, as x → ∞, y → ∞ and as x → -∞, y → -∞.
If you want to verify this, plug the equation into your calculator and look at the graph. How does it behave as you look at negative x-values? How about for positive x-values?

Hey there!
6/7 = ?/21
= 6/7 = x/21
CROSS MULTIPLY the FRACTION
6(21) = x(7)
6(21) = 7(x)
126 = 7x
7x = 126
DIVIDE 7 to BOTH SIDES
7x/7 = 126/7
CANCEL out: 7/7 because it give you 1
KEEP: 126/7 because it help solve for the x-value
NEW EQUATION: x = 126/7
SIMPLIFY IT!
x = 18
Therefore, your answer is: 18
BECAUSE 18/21 is equivalent to 6/7 and they both give you approximately 86% (or simply 0.86) if you’re rounding your percentage/decimal form
