3200 seconds 18 hours 46 minutes 1 day write the time from fastest to slowest in seconds
Answer: 46 minutes, 3,200 seconds, 18 hours, 1 day
Step-by-step explanation:
Convert all of these to seconds:
3,200 seconds = 3,200 seconds
18 hours = 18 * 60 minutes * 60 seconds = 64,800 seconds
46 minutes = 46 * 60 = 2,760 seconds
1 day = 24 hours * 60 minutes * 60 seconds = 86,400 seconds
From fastest to slowest in seconds:
46, minutes, 3,200 seconds, 18 hours, 1 day

What is the product?
(9t - 4)(-9 t - 4)
negative 81 t squared minus 16
negative 81 t squared + 16
negative 81 t squared minus 72 t + 16
negative 81 t squared + 72 t + 16
Answer:
The product is -81 t² + 16
Step-by-step explanation:
The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant
Multiply (ax) by (cx) ⇒ 1st × 1st
Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
Add the two products ⇒ like terms
Multiply (b) by (d) ⇒ 2nd × 2nd
Let us find the product of (9 t - 4) and (-9 t - 4)
Multiply the 1st two terms
∵ (9 t)(-9 t) = -81 t²
Multiply the ext-reams
∵ (9 t)(-4) = -36 t
Multiply the nears
∵ (-4)(-9 t) = 36 t
Add the like terms
∵ -36 t + 36 t = 0
Multiply the 2nd two terms
∵ (-4)(-4) = 16
Write the answer
∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16
∴ (9 t - 4)(-9 t - 4) = -81 t² + 16
The product is -81 t² + 16
A hot water tap filled a bath in 7 1/2 minutes,while a cold water tap fills it in 5 minutes,how long will it take to fill the bath when both taps are turned on together?
Answer:
3 minutes
Step-by-step explanation:
Let's say that the bathtub is 15L
It would take 7.5 mins to fill 15L
15L/7.5 = 2L per minute
The other tap would take 5 minutes to fill 15L
15L/5 = 3L per minute
3L per minute + 2L per minute = 5L per minute
15L/5L per min = 3 minutes

A rectangular plot of land is represented on a map by the vertices (10,10), (10, 90), (70.5, 90), and (70.5, 10), where the x- and y-coordinates are measured in yards. What is the area of the plot of land?
Answer:
Area of the plot of the land is 4840 square units.
Step-by-step explanation:
Let's draw the rectangle approximately on an x y plane. That would help us to find the length and width of the rectangle.
Answer: 4,480yd^2
Step-by-step explanation:
You have the x and y coordinates of the vertices (10, 10), (10,90), (70.5,90), and (70.5, 10) you have the coordinates: x and y as the first two which are the ones in bold. From that you do 70.5-10= 60.5.
Then you subtract the x and y coordinates again, which are underlined. From that do 90-10=80
Last you do 60.5x80=4,840 yards squared

Two sides of a right triangle measure 222 units and 444 units. What is the area of the square that shares a side with the third side of the triangle?
Answer:
the area of the square = x² = 147,852 ft²
Step-by-step explanation:
Given;
two sides of a right triangle, = 222 units and 444 units
let the third side of the right triangle that shares a side with a square = x
the third side is obtained by applying Pythagoras theorem, and assuming the third side to be either adjacent or opposite side.
x² = 444² - 222²
x² = 147,852
x = √147,852
x = 384.52 ft
Therefore, the area of the square = x² = 147,852 ft²
Answer:
20 = x^2
Step-by-step explanation:
to find c^2 you need to do:
a^2 + b^2 = c^2
so- 2x2 + 4x4 = 4+16= 20
20 = x^2 and since x is squared you do not find the square root
What is the Domain, Range, Decreasing, Increasing, Y-Intercept, X-Intercept, Maximum, and Minimum of the graph shown?
Step-by-step explanation:
I am not able to see the whole graph, but what I could see is that
domain=22
range=11
the x-intercept is there is no x-intercept!
y-intercept is 2
max is 10
minimum is 1
I am so sorry! But if you let me know about the decreasing and increasing values like that are they asking for? The greatest places in the graph where it increases or decreases?
Hope that helps :)

A garden sells soil by weight, rounded to the nearest tenth of a pound, Elizabeth has 43.479 pounds of soil. What is the weight rounded to the nearest tenth of a pound?
Answer: 43.48 Pounds
Step-by-step explanation:
Given
Elizabeth has 43.479 pounds of soil
Rounding off to the nearest tenth of a pound
Consider 79 which occurs after the decimal place
Converting it to 80 as it is nearest to 80
So, we can write 43.479 as 43.48 Pounds

In a javelin throw competition, five athletics score 56, 58, 63, 57 and 61 meters. What are their Mean and Median?
Answer:
Mean = 59
Median = 58
Step-by-step explanation:
Given the data for a Javelin throw :
56, 58, 63, 57 61 meters
Reordering the data: 56, 57, 58, 61, 63
Mean, m = Σx / n
n = sample size = 5
m = (56 + 57 + 58 + 61 + 63) / 5
m = 295 / 5
m = 59
The median : 1/2 (n+1)th term
1/2(5 +1) the term
1/2(6) = 3rd term
Median value = 58

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Write and solve an equation to find the answer. From midnight to 6:00 am, the temperature rose 8°C. At 6:00 am, the temperature was − 20 ° C. What was the temperature at midnight?
Answer:
The temperature at midnight is -12 degree Celsius
Step-by-step explanation:
Given -
Temperature at 6:00 PM = -20 degree Celsius
Let the temperature at midnight be X degree Celsius
From midnight to 6:00 am, the temperature rose by 8 degree Celsius
X - (-20) = 8
X = 8-20
X = -12 degree Celsius.
The temperature at midnight is -12 degree Celsius.
