(-3 ft)/(4 weeks) = -3/4 ft/wk = -0.75 ft/wk
The most approriate choice is ...
... (c) -0.75
The unit rate of change for the dropping lake's level is -0.75, calculated by dividing the total drop in levels (3 feet) by the total time (4 weeks). As the lake's level is dropping, the rate of change is negative.
Explanation:The question is asking us to find the unit rate of change in the lake's level, which means the amount the level has changed per unit of time. In this case, the time unit is weeks.
The lake has dropped 3 feet over 4 weeks, so to calculate the unit rate of change, we divide the total change (3 feet) by the total time (4 weeks). This results in a unit rate of change of 0.75 feet per week. However, since the lake's level is dropping, this should be a negative number.
So, the correct answer is (c) -0.75.

In a blueprint, each square has a side length of 1/4 inch.
(down below)
a. Ceramic tile costs $5 per square foot. How much would it cost to tile the bathroom?
It would cost $
to tile the bathroom.
b. Carpet costs $18 per square yard. How much would it cost to carpet the bedroom and living room?
It would cost $
to carpet the bedroom and living room.
Question 2
c. Which has a greater unit cost, the tile or the carpet? Explain.
The has a greater unit cost because $5 per square foot for the tile is than $ per square foot for the carpet.
1 blue square on drawing is length 1/4 in but that means 4ft in reality.
so one blue square area correspongs to 4x4 = 16 square feet.
(a) there 6 tiles for the batrhroom = 6x16 sq.ft = 96 sq.ft and the cost will be $480
(b) bedroom + living area = 7x8-8 tiles = 48 tiles = 48 x 16 sq.ft. = 768 sq.ft = 85.33 sq. yards. So the cost will be 85.33*18=$1535.94
(c) unit cost for tile: $5/sq.ft
unit cost for carpet: $1535.94/768sq.ft = $2/sq.ft
The tile has a greater unit cost ($5 per sq.ft) than carpet ($2 per sq.ft)
The exact costs for tiling and carpeting cannot be determined without the dimensions of the rooms. However, converting square inches to square feet or yards allows for cost calculation. Generally, tile has a greater unit cost than carpet when both are compared per square foot.
Explanation:Unfortunately, we cannot provide exact costs for tiling the bathroom or carpeting the bedroom and living room as the dimensions of these rooms are not provided. However, once you have total area in square inches, you can convert it into square feet or square yard by knowing that 1 square foot is 144 square inches and 1 square yard is 1296 square inches. After converting, you can then multiply the areas by the respective unit costs of the ceramic tile and the carpet to get the total costs.
For the unit cost comparison, generally, carpet is sold by square yard and tile is sold by square foot. To make an accurate comparison, we need to convert the price of carpet from per yard to per foot by dividing it by 9 (since 1 square yard = 9 square feet). If, for example, the carpet cost is $18 per square yard, this would equate to $2 per square foot. Comparing this to the tile cost of $5 per square foot, you can see that the tile has a greater unit cost.

what is the answers to questions 34 and 35???plz help me I don't understand
The answer to question 34:
Let 'x' = pounds of gravel. The ratio of mulch to gravel is given 2 1/4 | 1 1/3. Which equals 9/4 | 4/3 = 27/16.
So the total gravel and much is equal to x + 27/16x = 172
Solving for 'x'
43/16 x = 172
x = 172 (16/43) = 64 pounds of gravel Mulch = 27/16x = 64 (27/16)= 108 pounds
The answer to question 35:
A.) 1,080 beats per minute at rest and 1,500 beats per minute while running.
B.) 4,500 (while running) - 3,240 (at rest) = 1,260 more beats while running than at rest.
Hi Nicole,
Question 34:
2 1/4 pounds of mulch for every 1 1/3 pounds of gravel.
Gravel - 172 / 1 1/3 = 129
Mulch - 172 / 2 1/4 = 76.44444...
Question 35:
a. 18 beats in 15 seconds.
b. 25 beats in 10 seconds.
Part A:
Find beats per minute:
1 minute = 60 seconds
60 / 15 = 4
18 x 4 = 72
Answer - 72 beats per minute (Resting)
150 beats per minute (Running)
Part B:
72 times per minute resting
Find 25 times in 10 seconds in minutes,
1 minute = 60 seconds
60 / 10 = 6
25 x 6 = 150
So while running the friend has 150 beats per minute.
Find the number of beats in 3 minutes for both:
Resting:
72 x 3 = 216
216 beats in 3 minutes
Running:
150 x 3 = 450
450 beats in 3 minutes
Subtract:
450 - 216 = 234
Answer - Your friend's heart beat is 234 beats more in 3 minutes than at rest.

Nina has 3 feet ribbon that she wants to cut into 8 equal sized pieces. What is true about the length of each ribbon? A) each piece has 1/3 of 8 feet ribbon B) each piece has 1/8 of 3 feet ribbon C) each piece has 8/3 feet of ribbon
Answer:
B) each piece has 1/8 of 3 feet ribbon
Step-by-step explanation:
Given,
The total length of the ribbon = 3 feet,
Total number of pieces of the ribbon = 8,
If each piece has the same length,
So, the length of each piece
[tex]=\frac{\text{total length of the ribbon}}{\text{total pieces}}[/tex]
[tex]=\frac{3}{8}[/tex]
= 1/8 of 3 feet
Hence, OPTION B is correct.

In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.
Then by applying Pythagoras theorem in both the triangles.
h²= (3x + 5)² + (2x + 1)² ------(1)
h²= (5x + 1)² + 5² ------(2)
By equating both the equations
(3x + 5)² + (2x + 1)² = (5x + 1)² + 25
9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25
13x² + 34x + 26 = 25x² + 10x + 26
13x² - 25x² + 34x - 10x + 26 - 26 = 0
- 12x² + 24x = 0
12x² - 24x = 0
x² - 2x = 0
x(x - 2) = 0
x = 2
Now we will put x = 2 in the measure of sides of the kite.
Side 1 = (3x + 5)
= 3×2 + 5
= 11
Side 2 = (5x + 1)
= 5×2 + 1
= 11
Side 3 = (2x + 1)
= 2×2 + 1
= 5
Therefore, Total length of ribbon to line the long sides will be = 11 + 11
= 22 in.

The function y=25x+500 represents your monthly rent y when you pay x days late.
The domain is 0,1,2,3,4 and 5 what is the range?
x, y=25x+500
range = {500, 525, 550, 575, 600, 625}
For a given function we can define the domain as the set of the possible inputs of that function, and the range as the set of the possible outputs of that function.
We will find that the range is: {500, 525, 550, 575, 600, 625}
So, if for a given function f(x) we know that the domain is {x₁, x₂, ..., xₙ} then the range will be {f(x₁), ..., f(xₙ)}
Here we have the function:
y = f(x) = 25*x + 500
And we have the domain: {0, 1, 2, 3, 4, 5}
Then the values in the range are:
f(0) = 25*0 + 500 = 500f(1) = 25*1 + 500 = 525f(2) = 25*2 + 500 = 550f(3) = 25*3 + 500 = 575f(4) = 25*4 + 500 = 600f(5) = 25*5 + 500 = 625Thus the range is: {500, 525, 550, 575, 600, 625}

suppose both factors in a multiplication problem are multiples of 10. Explain why the number of zeros in the factors. Include an example.
5th grade work.
Answer:
10 * 10 = 100
20 * 10 = 200
30 * 40 = 1200
Step-by-step explanation:
Step 1: In both the factors, we have zeros. for example, multiplying 20 and 10, we get 200.
Step 2: Since there are two zeros (adding zeros in multiple), therefore, in the result we get 2 zeros
More examples:
10 * 200 = 2000, there are 3 zeros (1 +2 = 3 zeros)
200 * 200 = 40000, there 4 zeros ( 2+2 = 4)
Hope this will help you understand the concept.
When multiplying two multiples of 10, the number of zeros in the product equals the sum of the zeros in the factors. This is due to each zero representing a power of ten. The product in a multiplication of multiples of 10 will have a number of zeros that matches the combined number of zeros in the factors.
When both factors in a multiplication problem are multiples of 10, the result is a number with a zero for each zero in each factor.
This is because each zero represents a power of ten, and when we multiply by 10, we are increasing the power of ten.
For example, if we have two factors, 30 and 40 (which are multiples of 10), the product would be 1200. In this case, 30 has one zero and 40 has one zero, so the product, 1200, has two zeros.
The rule can also be applied to larger multiples of 10.
For instance, if we multiply 200 by 4000, the product would: 200 (two zeros) x 4000 (three zeros) equals 800,000 (five zeros).
The total number of zeros in the product equals the sum of the zeros in the factors.

The ball starts on the ground and travels in a parabolic shape as it reaches a maximum height and then returns to the ground . Suppose further that the ball reaches its maximum height of 15 feet in 2.2 seconds .
the ball reaches its maximum height of 15 feet in 2.2 seconds .
The ball takes 2.2 seconds to reach the maximum height from the ground
Ball takes another 2.2 seconds to reach the ground from the maximum height
