Answer:
1. [tex]4\sqrt{5}[/tex]
2. [tex]10\sqrt{10}[/tex]
Step-by-step explanation:
When you multiply radicals, you do the following
[tex]a\sqrt{b}\cdot c\sqrt{d}\\\\=ac\sqrt{bd}[/tex]
with that in mind
1.
[tex]\sqrt{16}\cdot \sqrt{5}[/tex]
here we don't need to multiply 16 times 5, because 16 = 4^2 and take the square root of it, gives you 4
[tex]=4\sqrt{5}[/tex]
2.
[tex]\sqrt{20}\cdot 5\sqrt{2}\\\\\longrightarrow 20 = 2^2\cdot 5\\\\=2\sqrt{5}\cdot5\sqrt{2}\\\\=(2\cdot5)\sqrt{5\cdot2}\\\\=10\sqrt{10}[/tex]

The price of a refrigerator is Rs 66,400 after including GST at the rate of 17% . what is the amount of GST.
need totally explanation
Answers
The amount of GST is Rs 9,647.87
Step-by-step explanation:
Given :• The price of a refrigerator = Rs 66,400
• Price including GST
• Rate of GST = 17 %
To Find :• The amount of GGS
Solution :★ GST Amount = Original cost of the product or service - (Original cost of the product or service) x (100 ) / (100 + GST%)
⇒ 66,400 − (66,400) × (100) / (100 + 17)
⇒ [tex]\mathsf{66,400 - ( 66,400 \times \dfrac{100}{(100 + 17)} )}[/tex]
⇒ 9,647.87
GST Amount = Rs 9,647.87
∴ The amount of GST is Rs 9,647.87

If a game player scored a 27 on the first game and a 39 on the second game, which number statement can be used to find what the player needs to score on the third game (S) to have a
mean (average) score of 36?
A. 27 +39+ S3 = 36
B. 363 = 27 +39 + S
C. (36 + 3) + S +27 +39
D. (27 +39 + S) + 3 = 36
Answers
Answer:D
Step-by-step explanation:
Answer: none of them are right...
Step-by-step explanation:
(27 + 39 + S)/3 = 36
27 + 39 + S = 36(3)
27 + 39 + S = 108
S = 108 - 39 - 27
S = 42

Jackson and his sister ran a hose from a bucket into their swimming pool. The hose sprays 1/3 of a gallon from the bucket every second. The bucket started with 32 gallons of water. How long will it take to empty the bucket?
Answers
Answer:
It will take 96 seconds to empty the bucket.
Step-by-step explanation:
To answer this all you have to do is divide 32 by 1/3. To do this you first have to turn 32 into and improper fraction by changing it into 31 3/3 and then multiplying 31 times 3 (93) and then adding 3, which gives you 96 so you get 96/3. You also have to change the division sign into a multiplication sign while also flipping 1/3 so its 3/1. Now you have to cross cancel and since the 3 in 96/3 can go into the 3 in 3/1 once, the 96/3 changes into 96/1 and the 3/1 changes into 1/1. Now you can multiply so 96 times 1 is 96 and 1 times 1 is 1 so you get 96/1 which is basically just 96 so your answer is that it will take 96 seconds to empty the bucket.

Answers
Answer:
tan²x + tan x - 12 = 0 (1)
suppose: tan x = t
(1)=> t² + t - 12 = 0
a = 1 b = 1 c = -12
⇒ Δ = b² - 4ac = 1 + 48 = 49 > 0 => has 2 solutions
=> t = [tex]\frac{1+\sqrt{49} }{2}=\frac{8}{2}=4[/tex]
or t = [tex]\frac{1-\sqrt{49} }{2}=\frac{-6}{2}= -3[/tex]
because t = tan x => tan x = 4 or tan x = -3
because x ∈ [0;2pi) => with tan x = 4 => x = arctan(4) or x = arctan(4) + pi
with tan x = -3 => x = arctan(-3) + pi

The elevation we call sea level is actually the average level of the sea. This means that at average sea level, the elevation is zero. In reality, the level of the sea rises and falls in what are called tides. Low tide is the point of lowest sea level in a tidal period. High tide is the point of highest sea level in a tidal period. The height above or below average sea level is called elevation. An elevation below sea level is considered a negative value, while an elevation above sea level is positive.
Winston lives near the ocean. He regularly brings an altimeter to the beach to measure the elevation of the ocean’s surface. You will use the data Winston gathered to complete tasks about the rising and falling of the ocean’s surface. When necessary, sketch a diagram of the situation on a separate sheet of paper to assist you.
On Monday at 1pm, when the ocean’s surface was at an elevation of 2.2 feet, Winston went to a surf shop that was 8.2 feet above the ocean’s surface. At 7 p.m. when the ocean’s surface was at an elevation of -2.4 feet, Winston ate dinner at a restaurant whose deck was 10 feet above the ocean’s surface.
What was the net change in the elevation of the ocean’s surface from 1 p.m. to 7 p.m.?
Answers
Answer:
-4.6 ft
Step-by-step explanation:
The question is asking for the net change in the ocean's surface elevation, so we can ignore the parts of the question that mention his own elevation at the time of the measuring. We can see at 1, the elevation was 2.2, and at 7, the elevation was -2.4. The net change is the whole change over the period of time, so we just need to find the difference between the two. Adding them together gives you the distance from each elevation the sea's surface was, which is -4.6 ft as the elevation decreased

the answer itself is m< 4=87
Step-by-step explanation:
Answer:
The answer is 87°
Step-by-step explanation:
A quadrilateral has an interior angle sum of 360°.
Given that three of the four angles in a quadrilateral are 89°, 80°, and 104°, we can create the following equation where x is the missing angle:
89° + 80° + 104° + x° = 360°.
All you have to do is add all the measures up and subtract from 360°.
89° + 80° + 104° + x° = 360° →
273° + x° = 360° →
x° = 87°.
Also, for any polygon, the interior angle sum is (n – 2) × 180°, where n is the number of sides.
A quadrilateral is a polygon with four sides so it's interior angle sum must be
(4 – 2) × 180° = 2 × 180° = 360°.
