On Thursday when the correct time is 5:00h, watch shows 4:24h.
What is ratio?Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.
If a and b are two values, their ratio will be a:b,
Given that,
The watch is set at 11:00 h on Sunday.
Also, the watch loses 8 seconds in every hour.
To determine the time in watch on Thursday,
In one day total hours = 24 hours.
from Sunday 11:00 to Thursday 11:00
Total hours = 24 x 4 = 96 hours
And 11:00 to 5:00, total = 6 hours
Total hours = 96 + 6 = 102 hours
Since, watch loses 8 seconds in 1 hour
So in 102 hours watch losses = 102 x 8 = 816 seconds
816 seconds = 816/60 minutes = 13.6 minutes
The watch loses 13.6 minutes in 102 hours.
So the exact time will be, 4 : 24.

Indigo launches a toy rocket from a platform. The height of the rocket in feet is given by h(t)=-16t² + 80t + 96 where t represents the time in seconds after launch. What is the rocket's greatest height?
The calculated value of the rocket's greatest height is 196 feet
Calculating the rocket's greatest height?From the question, we have the following parameters that can be used in our computation:
height function, h(t) =-16t² + 80t + 96
So, we have
h(t) =-16t² + 80t + 96
The maximum value of t is calculated as
t = -b/2a
So, we have
t = -80/(2 * -16)
Evaluate
t = 2.5
The rocket's greatest height is at t = 2.5
So, we have
h(2.5) =-16(2.5)² + 80(2.5) + 96
Evaluate
h(2.5) = 196
Hence, the rocket's greatest height is 196 feet

Rounding to the nearest tenth, we get that the length of KN is approximately 21.8.
What is a Pythagoras theorem?
The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship is often expressed in the form of the equation:
a² + b² = c²
To find the length of KN in this right triangle, you can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the hypotenuse is KL, and the other two sides are KM and KN. The theorem can be written as:
KL² = KM² + KN²
Substituting the given values, we get:
24² = 10² + KN²
Solving for KN, we get:
KN² = 24² - 10²
= 576 - 100
= 476
KN = √476
= 21.84
Hence, rounding to the nearest tenth, we get that the length of KN is approximately 21.8.

In this question, we have been given that the 6th grade students went on a field trip to see a ballet.
The students filled 702 seats leaving 35% vacant.
We need to find the total seats in the theater.
Let there were n seats in the theater.
Given that 35 percent of total seats were vacant.
So, we get an equation,
702 + (35% of n) = n
702 + 0.35n = n
(1 - 0.35)n = 702
0.65n = 702

Step-by-step explanation:
Hi can someone solve this with steps?
Answer:
42
Step-by-step explanation:
Given function:
[tex]f(x)=4x^4-2x^3-3x^2+3x[/tex]
Use the method of synthetic substitution to find the value of the function when x = 2.
Place the value of x in the left box and write the coefficients of the function in descending order, remembering to write a zero for the coefficient of any missing term.
(As there is no constant term in this function, the last coefficient should be written as zero).
[tex]4x^4-2x^3-3x^2+3x[/tex]
[tex]\begin{array}{c|ccccc}2&4&\:\:-2&\;\;-3&\;\:\:\:\:3&\;\;0\\\cline{1-1} \end{array}[/tex]
Bring the leading coefficient down:
[tex]\begin{array}{c|ccccc}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &&&\\\cline{2-6}&4\end{array}[/tex]
Multiply the number you brought down with the number in the box and put the result in the next column (under the -2):
[tex]\begin{array}{c|rrrrr}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &8&&\\\cline{2-6}&4\end{array}[/tex]
Add the two numbers in the second column together and put the result under them in the bottom row:
[tex]\begin{array}{c|rrrrr}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &8&&\\\cline{2-6}&4&6\end{array}[/tex]
Repeat:
[tex]\begin{array}{c|rrrrr}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &8&12&\\\cline{2-6}&4&6&9\end{array}[/tex]
[tex]\begin{array}{c|rrrrr}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &8&12&18\\\cline{2-6}&4&6&9&21\end{array}[/tex]
[tex]\begin{array}{c|rrrrr}2 &4&-2&-3&3&0\\\cline{1-1}&\downarrow &8&12&18&42\\\cline{2-6}&4&6&9&21&42\end{array}[/tex]
The last value, 42, is the value of the function when x is 2.
Therefore,
[tex]f(2)=4x^4-2x^3-3x^2+3x=42[/tex]
s is inversely proportional to t.
When s = 0.9, t = 2
Work out s when t = 0.6
Answer:
s = 3
Step-by-step explanation:
We model the proportion with the equation:
[tex]s =\frac{k}{t}[/tex]
We have s and t, but we need to find the k (i.e., the constant of proportionality) by plugging in the s and t we already have:
[tex]0.9=\frac{k}{2}\\ 1.8=k\\s=\frac{1.8}{t}[/tex]
To find s when t = 0.6, we simply plug in 0.6 for t in last equation we found with k:
[tex]s=\frac{1.8}{0.6}\\ s=3[/tex]

Answer:
x+5 or 5+x
Step-by-step explanation:
It seems we are looking for a math expression that is the same as English expression you wrote.The sum is what we get when we add numbers. Therefore, we could restate the English expression as what do we get when we add 5 to the number x? While we do not know what specific number x represents, we do know that if we add 5 to the number x we get 5 plus x. Now the question can be restated as, "How do we write 5 plus the number x?" Do you know the answer now? Does 5 + x sound right? How about x + 5? Both of these expressions are correct as they both represent the sum of 5 and the number x.

Since , the number gets divided completely
therefore the estimated quotient and the actual quotient will be 2110.
We first round the dividend and the divisor to the closest tens, hundreds, or thousands, and then divide the rounded figures to approximate the quotient. When the divisor in a division sum has two or more digits, it is helpful to first estimate the quotient before attempting to discover the exact number.
