Answer:
23 times. Last second of every hour.
On 24 hours, a digital clock displaying hours, minutes, and seconds all six digits change 23 times simultaneously.
Change of digits:The digits representing the seconds on the clock change for every second.
The minute digits change for each minute that is for every 60 seconds.
Similarly, the digits representing the hours on the clock change every 60 minutes.
This means that for all the six digits to change simultaneously, the last second must be such that it completes a minute, and the last minute should be such that it completes an hour.
This means that at the end of every hour, all the six digits change.
Which will happen 23 times for a 24 hours clock.

A rectangle has an area of 120 square feet and a width of 8 feet. please help
Answer:
Step-by-step explanation:
length = 120/8 = 15 feet
perimeter = (15 + 8) x 2 = 46 feet
The area is the product of the length and width then the length of the rectangle is 15 feet.
What is a rectangle?It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
A rectangle has an area of 120 square feet and a width of 8 feet.
Then the length of the rectangle will be
Area = Length × Width
120 = 8L
L = 15
Then the length of the rectangle is 15 feet.

Colin predicted whether he got answers right or wrong in his 50 question exam.
He identified the 12 questions he thought he got wrong.
It turns out that Colin got 5 questions right that he thought he got wrong.
Colin also got a total score of 42 out of 50 in the test.
What is the percentage accuracy he had with predicting his scores
Answer:
92.86%
Step-by-step explanation:
Total questions, T = 50.
Colin thought 8 questions were right.
Colin got 5 questions right that he thought he got wrong.
Total score, s = 45.
So, actual number of questions which are wrong are 5.
Score according to him = 50 - 8 = 42.
Now, we know percentage accuracy is given by :
Therefore, percentage accuracy he had with predicting his scores is 92.86%.

Answer:
The answer is p = 2.
Step-by-step explanation:
1) Divide both sides by 9.
[tex]p - 4 = - \frac{18}{9} [/tex]
2) Simplify 18/9 to 2.
[tex]p - 4 = - 2[/tex]
3) Add 4 to both sides.
[tex]p = - 2 + 4[/tex]
4) Simplify -2 + 4 to 2.
[tex]p = 2[/tex]
Therefor, the answer is p = 2.
Answer:
p =2
Step-by-step explanation:
9(p-4) =-18
9p-36=-18
9p = -18 +36
9p = 18
divide both side by 9

Find sin 0, where 0 is the angle shown.
Give an exact value, not a decimal approximation.
Answer:
Answer: Sin0 = 8/8.5
Step-by-step explanation:
Step-by-step explanation: What we have is a right angled triangle, with two sides given and one angle which is the reference angle (unknown angle).
The Sine of the angle is calculated as
Sin0 = opposite/hypotenuse
We have the opposite side (facing the reference angle) as 8 units and the hypotenuse (facing the right angle unknown), which we shall label as X.
To calculate the hypotenuse, we shall apply the Pythagoras theorem which is,
X² = 3² + 8²
X² = 9 + 64
X² = 73
Adding the square root sign to both sides of the equation, we now have
X = √73
X = 8.5 (approximately)
Now that we have the hypotenuse as 8.5, the Sine of the angle can now be calculated as
Sin0 = opposite/hypotenuse
Sin0 = 8/8.5

When the given mixed fractions are solved and tired to prove that both the sides are equal, the result will show that the given equation is correct.
What is a mixed fraction?A proper fraction that is less than one whole must represent the fractional portion of the mixed number. When a fraction is written properly, the top number, or numerator, must be less than the bottom number, or denominator.
A mixed fraction is one that has both a whole number and a fractional component. Additionally known as "Mixed numerals"

Answer:
45.7
Step-by-step explanation:
Hello there!
We can calculate the missing angle using trigonometry
here are the trigonometric ratios
sin = opposite over hypotenuse
cos = adjacent over hypotenuse
tan = opposite over adjacent
We are given x's opposite side length (8) and x's adjacent side length (7.8)
we are given the information to use the trigonometric ratio tangent
so now we create an equation (remember tan - opposite over tangent)
[tex]tan(x)=\frac{8}{7.8}[/tex]
now we solve for x
[tex]\frac{8}{7} =1.025641026[/tex]
we're left with
[tex]tan(x) =1.025641026[/tex]
finally we want to get rid of the tan
To do so we take the inverse of tan (arctan^-1) and apply it to each side
[tex]arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243[/tex]
so x = 45.7252243
finally we round to the nearest tenth and get that the answer is

Answer:
100 by 190 in.
Step-by-step explanation:
Ratios are only equal if both numbers are divided by the same number.
10 : 19 = (10 × 10) : (19 × 10)
10 : 19 = 100 : 190
You have not mentioned if there is more than one answer so lets check the rest:
10 : 19 = (10 × 10.7) : (19 × 10 and 3/19)
10 : 19 ≠ 107 : 193
10 : 19 = (10 × 10.7) : (19 × 10)
10 : 19 ≠ 107 : 190
10 : 19 = (10 × 10) : (19 × 10 and 3/19)
10 : 19 ≠ 100 : 193

Hot dog buns come in boxes of 8. On Friday's game, the chef uses 2 1/6 boxes of hotdog buns. On Saturdays game, the chief uses 1 4/6 boxes of hotdog buns. How many boxes of hotdog buns did the chef use altogether?
Answer:
3 and 5/6
We know this because it says the chef uses 2 1/6 boxes on one day and 1 4/6 on the other.
2 + 1 = 3
1/6 + 4/6 = 5/6 (cannot be simplified)
