Answer:
162
Step-by-step explanation:
[tex] { \sqrt{xy} } = 3[/tex]
[tex] = > ( { \sqrt{xy} })^{2} = {3}^{2} [/tex]
[tex] = > xy = 9[/tex]
Also ,
[tex]x - y = 12[/tex]
[tex] = > {(x - y)}^{2} = {12}^{2} [/tex]
[tex] = > {x}^{2} + {y}^{2} - 2xy = 144[/tex]
Putting the value of 'xy' above gives :-
[tex] {x}^{2} + {y}^{2} - 2 \times 9 = 144[/tex]
[tex] = > {x}^{2} + {y}^{2} = 144 + 18 = 162[/tex]

Q1 [5]
A cliff is located on the edge of a river. An observation tower, 11 meters tall, is built on the
cliff. The angle between the top of the cliff and the opposite side of the river is 20°, while the angle
between the top of the tower and the opposite side of the river is 30° Let's define h as the height of
the cliff and w the width of the river.
iii. Draw the cliff, tower and river writing all the information given (1pt)
Find the width of the river (4 pt)
iv.
Answer:
The required drawing showing the cliff, river, and tower as well as the details in the question is attached, please find alongside the answer
The width of the river is approximately 51.55 meters
Step-by-step explanation:
The height of the observation tower = 11 meters
The angle of elevation of the cliff top and the opposite side of the river = 20°
The angle of elevation of the tower top and the opposite side of the river = 30°
Therefore, by sine rule, we have;
h/sin(20) = w/sin(60)
11/sin(10) = length, l/sin(60)
l = sin(60) ×11/sin(10) ≈ 54.86 meters
w = l × cos (20) = 54.86 meters × cos (20) ≈ 51.55 meters
The width, w, of the river is approximately 51.55 meters.

Answer:
[tex]\boxed{A. a < 7}[/tex]
Step-by-step explanation:
Hey there!
Well given,
2a + 6 < 4(a - 2)
We need to simplify for a.
Distribute 4, 4(a - 2)
4*a = 4a
4*-2 = -8
2a + 6 < 4a - 8
-2a to both sides
6 < 2a - 8
+8 to both sides
14 < 2a
14 ÷ 2 = 7
Thus, a < 7.
Hope this helps :)
Answer:
a > 7
Step-by-step explanation:
Distribute the 4 on the right side. (Distributive Property)
Put the like terms together.
Combine like terms.
Divide on both sides (divide by the coefficient) and flip the inequality sign.
Your final answer should a > 7
Rearrange the equation so w is the independent variable.
-2u + 6w = 9
u = _______
Answer:
u = 3w -9/2
Step-by-step explanation:
-2u + 6w = 9
Subtract 6w from each side
-2u + 6w-6w = 9-6w
-2u = 9-6w
Divide each side by -2
-2u /-2 = 9/-2-6w/-2
u = 3w -9/2
Which expression is equivalent to √100 + 4√10 + 3 − 8√10?
10 − √10
−4√10 + 13
3 − 2√10
√10
Answer:
2nd option
Step-by-step explanation:
√100 + 4√10 + 3 - 8√10
√100 can be written as 10
so it becomes,
10 + 4√10 + 3 - 8√10
-4√10 + 13
Hope this helps
plz mark as brainliest!!!!!!
The equivalent expression to √100 + 4√10 + 3 - 8√10 is [tex]- 4\sqrt{10} + 13[/tex].
What are surds and indices?We know there are two types of radicals one is surds when the number has been raised by such power that it is greater than zero and less than one,
The other type of radicals are indices where a number is raised to such power that is greater than one.
The given expression is √100 + 4√10 + 3 - 8√10.
= [tex]\sqrt{10\times 10} + 4\sqrt{10} + 3 - 8\sqrt{10}[/tex].
Now, we'll combine the terms having the same radical value inside.
[tex]= 10 + 3 - 4\sqrt{10}[/tex].
[tex]= 13 - 4\sqrt{10}[/tex].
Or,
[tex]= - 4\sqrt{10} + 13[/tex].

roads and $7.00 per minute for highways. Max
rode on a taxi cab and traveled over both local
roads and a highway. If he spent $59 on a ride
that lasts 11 minutes in total, how much time
did Max spend in the taxi going over the local
roads?
Answer:
5 minutes with 7$,6 minutes with 4$
Step-by-step explanation:
Let's just say that he travelled only local

Segment PE has endpoints P(-4,4) and E(0,-4). Find the coordinates of point Q such that PQ:QE is 1:3. Enter the coordinates below
Answer:
(-3, 2)
Step-by-step explanation:
Given that point Q, partitions segment PE, such that PQ:QE is 1:3, coordinates of point Q is found using the formula below:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
Where,
[tex] P(-4, 4) = (x_1, y_1) [/tex]
[tex] E(0, -4) = (x_2, y_2) [/tex]
[tex] m = 1, n = 3 [/tex]
Plug in the necessary values to find x and y coordinates for point Q as follows:
[tex] x = \frac{mx_2 + nx_1}{m + n} [/tex]
[tex] x = \frac{1(0) + 3(-4)}{1 + 3} [/tex]
[tex] x = \frac{0 - 12}{4} [/tex]
[tex] x = \frac{-12}{4} [/tex]
[tex] x = -3 [/tex]
[tex] y = \frac{my_2 + ny_1}{m + n} [/tex]
[tex] y = \frac{1(-4) + 3(4)}{1 + 3} [/tex]
[tex] y = \frac{-4 + 12}{4} [/tex]
[tex] y = \frac{8}{4} [/tex]
[tex] y = 2 [/tex]
The coordinates of the point Q are (-3, 2))
What is the solution to the following equation?
-50 = -5x - 3(5x + 15)
Answer:
Step-by-step explanation:
-50 = -5x - 3(5x + 15) {Use distributive rule}
-50 = -5x + 5x *(-3) + 15*(-3)
-50 = -5x - 15x - 45 {Combine like terms}
-50 = -20x - 45 {Add 45 to both sides}
-50 + 45 = -20x
-5 = -20x {Divide both sides by -20}
-5/-20 = x

Matea recorded that water levels in one part of the river fell 1.05 millimeters per year for 2.48 years. Describe how you could estimate the total variation in water level.
Answer:
The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.
Step-by-step explanation: I'm taking the test
Answer:
Sample response: The decrease of the decimal rate -1.05 mm/year can be rounded to -1. You don’t need to round 2.48 because you’re multiplying by -1. Since -1.05 is negative and rounded to a greater value, the estimate could be adjusted to a slightly lesser value, maybe -2.5 or -2.6.

Latoya drove 240 miles using 9 gallons of gas. At this rate, how many gallons of gas would she need to drive 216 miles?
Answer:
8.1 gallons of gas
Answer:
8.10 or 8
Step-by-step explanation:
you divide the miles with how many tanks of gas was used to find how much 1 gallon can take you.
240/9=26.66
now that you know how much 1 gallon of gas can take you you have to divide 216 by 26.66 to find how many gallons you would need
216/26=8.10
