A metallic sphere is immersed in water in a cylindrical container causing a rise in the level of water by 7.5cm if the cylinder has a base radius of 7cm find the radius of the sphere to 2 decimal places
Answer:
6.51 cm
Step-by-step explanation:
Since the sphere causes the water level in the cylindrical container to rise and thus increase by its own volume, the volume of the sphere is V = 4πr³/3 where r = radius of sphere. The volume rise of the container is thus V' = πR²h where R = radius of base of cylinder = 7 cm and h = height of water level = 7.5 cm.
Since V = V',
4πr³/3 = πR²h
dividing through by π, we have
4r³/3 = R²h
multiplying both sides by 3/4, we have
r³ = 3R²h/4
taking cube-root of both sides, we have
r = ∛(3R²h/4)
Substituting the values of the variables into the equation, we have
r = ∛(3(7 cm)² × 7.5 cm/4)
r = ∛(3 × 49 cm² × 7.5 cm/4)
r = ∛(1102.5cm³/4)
r = ∛(275.625 cm³)
r = 6.508 cm
r ≅ 6.51 cm to 2 decimal places

In quadrilateral ABCD, m∠A = 8x-65,
m∠B = 6x-53,
M ∠ C = x+ 121,
and m ∠ D = 6x+21.
a. Find m∠A, m∠B, M ∠ C , and m ∠ D .
b. Classify quadrilateral ABCD as a kite, trapezoid, or isosceles trapezoid. Justify
your answer.
c. What is true of the side lengths?
Answer:
Sum of interior angles of a quadrilateral is 360°Find x first:
m∠A + m∠B + m∠C + m∠D = 360°8x - 65 + 6x - 53 + x + 121 + 6x + 21 = 36021x + 24 = 36021x = 336x = 336/21x = 16Find angle measures:
m∠A = 8*16 - 65 = 63°m∠B = 6*16 - 53 = 43°m∠C = 16 + 121 = 137°m∠D = 6*16 + 21 = 117°Each angle has a different measure, it means the sides are all different.
The quadrilateral ABCD is likely a trapezoid.

The complete sentence is:
Walnuts stay fresh longer in the refrigerator or freezer.
Step-by-step explanation:
A complete sentence is a sentence that displays a complete idea. It comprises of a subject and a predicate that includes verb too.
From the given two sentences, the complete sentence is the second sentence. 'Walnuts' is the subject and 'stay fresh longer in the refrigerator or freezer' is the predicate. A complete idea about the freshness of the walnuts have been stated in the sentence. On the other hand, the first sentence is a run-on sentence. In such a sentence, two sentences are merged together. This is done by adding the punctuation mark or coordinating conjunction to merge the sentences.
Answer:
Run-on sentence

12
y
13y - y
Answer:
None
Step-by-step explanation:
0y+3y=3y.
10+3y=13y, 13y is not equal to 3y
y+12=12y, 12y is not equal to 12y
12 is not equal to 3y
y is not equal to 3y
13y-y=12y which is not equal to 3y.

A company made 700000 profit last year. It says this was 12percent more than the year before. What was the profit made the year before
Answer:
784000
Step-by-step explanation:
Given data
Profit = 700000
Let us begin by finding what 12% of 700000 is
=12/100* 700000
=0.12* 700000
=84000
Hence the profit made last years was
=84000+700000
=784000
It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet. Please help
Answer:
The set of natural numbers is the set of all positive integers, then this set is:
{1, 2, 3, ...}
and the 24th letter of the alphabet is x
Now we want to write the expression given in the sentence "It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
We can "break" this in parts, so it is easier to understand.
Then:
"...the sum of the first 3 natural numbers..."
is:
1 + 2 + 3
Then:
"...the sum of the first 3 natural numbers, followed by the 24th letter of the alphabet"
This can be written as:
(1 + 2 + 3) + x
Now we can analyze the complete sentence:
"It is one more than the sum of the first three natural numbers, followed by the 24th letter of the alphabet"
This is equal to the expression we found above plus one, then we can write this as:
[(1 + 2 + 3) + x] + 1
[6 + x] + 1
6 + x + 1
7 + x
24% of 40
I need it worked out pls thank uuu:)
Step-by-step explanation:
24% is the same as 6/25
[tex] \frac{6}{25} \times 40 \\ = \frac{48}{5} = 9.6[/tex]
Answer:
9.6
Step-by-step explanation:
24% of 40 = 0.24 × 40 = 9.6

solve for sk and angle PQR.
Answer:
arc SK = 144°
∠PQR = 60°
Step-by-step explanation:
∠M = 1/2 (arc SK - arc NL)
37° = 1/2 (arc SK - 70°)
arc SK = 2*37° + 70° = 144°
∠PQR = 1/2 (small arc PQ) = 1/2 (360° - 240°) = 60°
