Math quest after a winter storm, the depth of the snow on cherry street was 10 \text{ cm}10 cm10, space, c, m. but then, the snow started melting at a rate of \dfrac{1}{3} \text{ cm}31 cmstart fraction, 1, divided by, 3, end fraction, space, c, m per hour.what was the depth of the snow on cherry street after 333 hours?
Answers
We are given that the initial depth of snow is 10 cm while the rate of melting is 1/3 cm per hour. So the melted ice after 3 hours is:
melted = (1/3 cm/hr) * 3 hours = 1 cm
Hence the depth left is:
depth = 10 cm – 1 cm = 9 cm
Answer:
9 cm
Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of [tex]\frac{1}{3}[/tex], so the snow melted in x hours will be [tex]\frac{1}{3}x[/tex].
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:
[tex]10-\frac{1}{3}x[/tex]
To find the depth of snow after 3 hours we will substitute [tex]x=3[/tex] in our expression.
[tex]10-\frac{1}{3}\times 3[/tex]
[tex]10-1[/tex]
[tex]9[/tex]
Therefore, the depth of the snow on cherry street after 3 hours will be 9 cm.

If tap and bre are supplementary and bre is its own complement, find the measure of tap. explain how you arrived at your answer
Answers
m∠bre + m∠bre = 90°
m∠bre = 45°
Then, for the relationship of bre and tap, we have the equation,
m∠bre + m∠tap = 180°
45° + m∠tap = 180°
m∠tap = 135°
The measure of tap is equal to 135°.

If x+z=15x+z=15 and w+y=10w+y=10, what is the value of (3w+3y)(2x+2z)(3w+3y)(2x+2z) ?
Answers
Answer:
The value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared is [tex]\(810,000\).[/tex]
Explanation:
To find the value of [tex]\((3w+3y)(2x+2z)\)[/tex], we can first simplify each factor:
[tex]\((3w+3y) = 3(w+y)\)[/tex]
[tex]\((2x+2z) = 2(x+z)\)[/tex]
Given that [tex]\(w+y = 10\) and \(x+z = 15\)[/tex] , we can substitute these values into the expressions:
[tex]\((3w+3y) = 3(10) = 30\)[/tex]
[tex]\((2x+2z) = 2(15) = 30\)[/tex]
Now, we multiply these two simplified expressions together:
[tex]\((3w+3y)(2x+2z) = 30 \times 30 = 900\)[/tex]
So, the value of [tex]\((3w+3y)(2x+2z)\) is \(900\).[/tex]
To find the value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared:
[tex]\((3w+3y)(2x+2z)^2 = (900)^2 = 810,000\)[/tex]
Therefore, the value of [tex]\((3w+3y)(2x+2z)\)[/tex] squared is [tex]\(810,000\).[/tex]

S is between T and V. R is between S and T. T is between R and Q. QV=18, QT=6, and TR=RS=SV. Find RS , QS , TS , and TV.
Answers
4 4 4
-----Q-----------------------T----------------R---------------S---------------V
<----------6----------->
<-----------------------------------------18--------------------------------->
QT = 6 (given)
QV = 18 (given)
TR=RS=SV (given)
Then TV = 18-6 = 12 and since TR=RS=SV , then each segment = 12/3 =4
RS = 4
QS = 14
TS = 8
and TV. = 12
A line can have as many points as possible, and multiple lines can have similar points. The values of RS, QS, TS and TV are:
[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]
S is a point between lines T and V means:
[tex]TV = TS + SV[/tex]
R is a point between lines S and T means:
[tex]TS = RS + TR[/tex]
T is a point between lines R and Q means
[tex]RQ = TR + QT[/tex]
Given that:
[tex]QT = 6\\QV = 18[/tex]
This means that Q is a point between lines QT and QV. So:
[tex]TV = QV - QT[/tex]
[tex]TV = 18- 6[/tex]
[tex]TV = 12[/tex]
[tex]TR=RS=SV[/tex] means that:
[tex]TV = TR+RS+SV[/tex]
Because [tex]TR=RS=SV[/tex], the equation becomes:
[tex]TV = TR+TR+TR[/tex]
[tex]TV = 3TR[/tex]
Substitute 12 for TV
[tex]12 = 3TR[/tex]
Divide both sides by 3
[tex]4 = TR[/tex]
[tex]TR =4[/tex]
Hence:
[tex]TR=RS=SV=4[/tex]
[tex]TS = RS + TR[/tex] gives
[tex]TS = 4 + 4[/tex]
[tex]TS = 8[/tex]
Next, we calculate the measure of QS from lines QV and SV
Point S is common between QS and SV. This means:
[tex]QV = QS + SV[/tex]
Make QS the subject
[tex]QS =QV -SV[/tex]
[tex]QS =18-4[/tex]
[tex]QS =14[/tex]
Hence, the values of RS, QS, TS and TV are:
[tex]RS = 4\\QS =14\\TV = 12\\TS = 8[/tex]

A rectangular box is to have a square base and a volume of 80 ft3. the material for the base costs 45¢/ft2, the material for the sides costs 10¢/ft2, and the material for the top costs 28¢/ft2. letting x denote the length of one side of the base, find a function in the variable x giving the cost (in dollars) of constructing the box.
Answers
V = Ah = 80
Since the base is a square with side x, then the area is equal to x². Hence, we can express h in terms of x.
80 = x²h
h = 80/x²
Now, each lateral side of the rectangular box is in the shape of a rectangle with a length of h and a width of w. Hence, the equation for the total cost would be:
Total Cost = Cost per area of lower base + Cost per area of upper base + 4(Cost per area of lateral side)
Total Cost = 0.45x² + 0.28x² + 4(0.10h*x)
Total Cost = 0.73x² + 0.4hx
Since h = 80/x²,
Total Cost = 0.73x² + 0.4(80/x²)(x)
Total Cost ($) = 0.73x² +32/x

Pauley graphs the change in temperature of a glass of hot tea over time. He sees that the function appears to decrease quickly at first, then decrease more slowly as time passes. Which best describes this function? It is linear because the graph decreases over time. It is linear because there is both an independent and a dependent variable. It is nonlinear because linear functions are increasing functions. It is nonlinear because linear functions increase or decrease at the same rate.
Answers
Answer:
It is nonlinear because linear functions increase or decrease at the same rate.
Step-by-step explanation:
A linear function is a function with a constant rate of change. This means it increases or decreases at the same rate.
Since this function decreases quickly and then more slowly, it does not have a constant rate of change; it is not linear.
