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.

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✔

what function models the height of the periscope lens at time t? If the periscope reaches its maximum Heught after ascending for 22 seconds, what is the maximum height in feet? ( 24 inches above the surface and ascends at 6 inches per sec.)
Answer:
Step-by-step explanation:
First we are going to find the function which models the height of the
periscope lens at time t.
Let the 2 be height of the periscope.
The height of the periscope at the beginning is 24 inches. It ascends at 6
inches per second. The expression which describes how much it has raised,
at the moment, is 6t.
The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.
To find maximum height of the periscope, we need to evaluate function
for + = 22.
2 = 24 + 6(22)
= 24 + 132
156
Substitute 22 for t.
Multiply.
Maximum height in inches is 156.
We know that 1 foot is 12 inches.
So the function that describes converting feet to inch is y :
= 12x. Where y
represents number of inches and a number of feet.
U = 12.2
156
12x
12
-n=
156
12
2 = 13
Substitute 156 for y.
Divide both sides by 12.
Maximum height in feet is 13.
The height function modeled by the periscope is an illustration of a linear function.
The height function modeled by the periscope is [tex]\mathbf{h(t) = 24+ 6t}[/tex]The maximum height is 156 inchesThe given parameters are:
[tex]\mathbf{Start = 24\ inches}[/tex]
[tex]\mathbf{Rate = 6\ inches/second}[/tex]
The function model of the height is calculated using:
[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]
Where: t represents the time in seconds
So, we have:
[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]
This gives
[tex]\mathbf{h(t) = 24+ 6t}[/tex]
After 22 seconds, the height of the periscope would be
[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]
Multiply
[tex]\mathbf{h(22) = 24+ 132}[/tex]
Add
[tex]\mathbf{h(22) = 156}[/tex]
Hence, the maximum height is 156 inches

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

Answer:
OPTION 1, 3
Step-by-step explanation:
I don't know how to explain why these are the correct options, except for basing my observations from the given graph.
Option 1: Attah Shipping does deliver a 20-kg package for $60 [as given by coordinates, (20, 60) -- orange line].
Option 3: The 30-kg line is the last, right-most line on the graph. That's the last point where Kwan Shipping's blue line crosses (within the observable region of the graph). If you look carefully, it is the same height as where Attah Shipping's 25-kg mark is. This means that a 30kg package costs $75 for Kwan Shipping, while it costs Attah Shipping $75 to ship a 25kg package. (You could draw a horizontal line across y = 75 to see what I'm talking about).

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.

Answer:
1 Expert Answer
X + Y + Z = 264. Since Y is 1 bigger than X, Y = X + 1. Since Z is 1 bigger than Y, Z = Y + 1. But Y = X + 1, so Z = (X + 1) + 1 = X + 2.
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.

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.
