Answer:
≈ 404 m²Step-by-step explanation:
Volume of a sphere:
V = 4/3πr³LSA = TSA of a sphere:
S = 4πr²We have V = 764 m³, find the radius:
4/3πr³ = 764r³ = (3*764/4π)r³ = 182.39 (rounded)r = √182.39r = 5.67 m (rounded)Find the surface area:
S = 4*π*(5.67)²S = 404 m² (rounded)[tex] \boxed{\tt{ \bold{Hello\:Mister\:Brainly!}}}[/tex]
____________
Step by step :S = 4πr²
S = 4π × (V = 4/3πr³)²
S = 4π × (764 = 4/3 × 3,14 × r³)²
S = 4π × (764 × 3/4 = 3,14r³)²
S = 4π × (573 ÷ 3,14 = r³)²
S = 4π × (r³ ≈ 182,5)²
S = 4π × (r ≈ 5,67)²
S = 4 × 3,14 × 5,67²
S ≈ 404m²✔

Which of the following does not represent a function?
Answer:
i think it's C sorry if it's wrong
Step-by-step explanation:
i took the test and got it right so
Answer:
The third option
Step-by-step explanation:
1. To determine whether a relation is a function given a graph, use the
following criterion:
if every vertical line you can draw goes though only 1 point, then the relation is a function If you can draw a vertical line that goes though 2 or more points, y is not a function of x. This is called the vertical line test.2. As you can see, if you draw a vertical line at a specific place in the third graph, it will go through 2 or more points.
Therefore, the correct answer is the third option/graph.

Answer:
40/3
[tex]15 \times x = 200 \\ 15x = 200 \\ x = 200 \div 15 \\ x = \frac{40}{3} [/tex]
The painter should work at least 13.33 hours to earn $200.
What is inequality?An inequality is a mathematical statement showing the non-equal comparison between two expressions.
Given that, a painter earns $15 per hour. We need to find the minimum number of hours he must work to earn at least $200,
So, let the minimum number of hours be x,
15x ≥ 200
This will be the inequality,
To find the minimum number of hours we will find the value of x,
15x ≥ 200
Divide by 15
x ≥ 200/15
x ≥ 13.33
Hence, the painter should work at least 13.33 hours to earn $200.

which equation or inequality shows the relationship between the plotted points on the number line
A. -4 > 3
B. -4 > -3
C. 3 > -4
D. 3 < -4
Answer:
C.3>-4
Step-by-step explanation:
I I can't agree with a b and d cause a shows that -4 he's greater than three but that is wrong because three is greater than -4 and part B shows that -4 is greater than -3 and according to the order of the number line -3 must be greater than negative 4 then part d shows that 3 is less than -4 which is also not correct because 3 is greater than -4 and part C shows the relationship between the plotted points on the number line clearly because 3 is greater than-4

Last Saturday, Taamir, Ali, Jaafar and Amal scored a total of 500 runs at cricket. Which of these statements must be true?
A) Each player made over 100 runs.
B) Each player made exactly 125 runs.
C) No player made over 250 runs.
D) At least one player made over 100 runs
Answer:
D At least one player made over 100 runs

At least means that more than one player made over 100 runs. Seeing as there are 4 people scoring a total 500 runs, a player had to make over 100 runs to reach the total of 500 runs collectively
Joe drove 165 miles in 3 hours. How many miles can he drive in 8.
1. What is the Standard Form of the line with x-intercept of 6 and y-intercept of 2?
2x + 6y = 8
6x + 2y = 8
6x + 2y = 12
2x + 6y = 12
Step-by-step explanation:
these intercepts are also points.
for an y- intercept x =0.
for an x- intercept y = 0.
so, we have the points (6,0) and (0, 2).
the regular equation for a line is
y = ax + b
(0, 2) gives us b directly :
2 = a×0 + b = b
and from there with the second point
0 = a×6 + 2
0 = 3a + 1
-1 = 3a
a = -1/3
so, the equation is
y = (-1/3)x + 2
and transform to standard form
3y = -x + 6
x + 3y = 6
that is the same as
2x + 6y = 12 of the answer options.
Bronze which costs $7.05/kg is made by
combining copper which costs $6.20/kg with
tin which costs $8.70/kg. Find the number of
kg of copper and tin required to make 5 kg of
bronze.
Find the number of kg of copper and tin required to make 15.3 kg of bronze. (NO LINKS)
Answer: 3.3 kg of Cu, 1.7kg of Sn
I abbreviate copper as Cu and tin as Sn.
Step-by-step explanation:
For 5 kg of $7.05$/kg bronze: Let x be the mass of Cu. The mass of Sn would be 5-x.
Multiply these two masses by their respective element cost.
Cu = ($6.20/kg)x [The total value of copper in 5 kg of bronze]
Sn = ($8.70/kg)(5-x) [The total value of tin in 5 kg of bronze]
We know that:
($6.20/kg)x + ($8.70/kg)(5-x) = $7.05
Solve for x. I get
x= 3.3 kg of Cu
5-x = 1.7kg of Sn
==
Check the result for 5 kg of bronze:
(3.3 kg of Cu)*($6.20/kg) = $20.46 cost of Cu
(1.7kg of Sn)*($8.70/kg) = $14.79 cost of Sn
Thus, the total cost for 5kg of bronze is $35.25. That makes it $7.05/kg.
