19.87 = 100%
If you divide both sides by ten, you would get what ten percent is.
1.987 = 10%
Multiply this by two to get 20%.
3.974 = 20%
Minus twenty percent from the original amount.
18.87 minus 3.974 = 15.886 after the discount.
What is the missing degree measure of the third angle of the triangle below?
46°
56°
68°
90°
Answer:
56 degrees
Step-by-step explanation:
Hello there!
Remember the sum of the angles in a triangle is equal to 180
so to find the missing angle we subtract the given angles from 180
180 - 34 - 90 = 56
so we can conclude that the measure of the missing angle is 56 degrees
Note: the little square at the bottom left of the triangle indicates that the angle is a right angle. The measure of a right angle is 90 degrees so thats where the 90 came from
Answer:
third angle Δ = 56°hope it help you

Finish Times of 30 Runners
in the 100-meter Dash
Mean MAD
Last Year 16.2s 1.2
This Year 14.7s 1.9
The is greater for this year’s 100-meter dash, which suggests that all 30 students equally.
Answer:
The first one is mean absolute deviation and the second one is did not improve
Step-by-step explanation:
I took the test
The MAD is greater for this year’s 100-meter dash, which suggests that all 30 students did not improve equally.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
The given table is:
Mean MAD
Last Year 16.2 s 1.2
This Year 14.7 s 1.9
Looking at this table we can see that this year, the meantime is smaller than the one from last year, so the runners are faster on average.
The mean absolute deviation is bigger, but the change in the mean is bigger.
difference of the mean 16.2 - 14.7 = 1.5
difference of the MAD 1.9 - 1.2 = 0.7
This means that the average speed of the runners increased since last year,
and the fact that the MAD increased means that not all the runners increased their speed at the same rate, so now the speeds of the different runners are not as alike as last year.

The period of the given function is π/5. The option 4 is the correct option.
What is the period of the cosine function?
The cosine function is the trigonometric function, hence it is known as the periodic function.
The period of a function is the total interval in which the function repeats itself over and over again the of the function for a complete cycle. If,
[tex]f(x)=A\cos(Bx+C)+D[/tex]
Then the period of the cosine function can be given as,
[tex]I=\dfrac{2\pi}{|B|}[/tex]
Given information-
The given function in the problem is,
[tex]f(x)=\cos(10x)[/tex]
The above function is the cosine function. Let a cosine function of in with values of [tex]x[/tex] 0 to 2π.
Now the period of the periodic function is the interval of [tex]x[/tex] values in which the the cycle of graph repeats itself in both directions.
Compare the given function with above equation we get,
[tex]B=10[/tex]
Thus the period of the [tex]\cos (10x)[/tex] is,

A rectangular piece of metal 12 cm long 18 cm wide and 10 cm high is melted and recast into 45 cylindrical plates,each of radius 1.2 cm.Find the thickness of each plate giving your answer correct to 2 decimal places?
Answer:
10.61 cm
Step-by-step explanation:
From the question,
The volume of the rectangular piece of metal = Volume of the 45 cylindrical plates.
Volume of a cuboid = 45×volume of a cylinder
lwh = 45×πr²h..................... Equation 1
Where l = length of the rectangular piece of metal, w = width of the rectangular piece of metal, h = height of the rectangular piece of metal, r = radius of the cylindrical plates, h = thickness of the cylindrical plates.
make h the subject of the equation
h = lwh/(45πr²).................... Equation 2
Given: l = 12 cm, w = 18 cm, h = 10 cm. r = 1.2 cm
Constant: π = 3.142.
Substitute these values into equation 2
h = (12×18×10)/(45×3.142×1.2²)
h = 2160/203.60
h = 10.61 cm.

Let's solve your equation step-by-step.
4x + x + 5 − 9 + x = −3 − 7 + x
Step 1: Simplify both sides of the equation.
4x + x + 5 − 9 + x = −3 − 7 + x
4x + x + 5 + −9 + x = −3 + −7 + x
( 4x + x + x ) + ( 5 + −9 ) = ( x ) + ( −3 + −7 )
( Combine Like Terms )
6x + −4 = x + −10
6x − 4 = x − 10
Step 2: Subtract x from both sides.
6x − 4 − x = x − 10 − x
5x − 4 = −10
Step 3: Add 4 to both sides.
5x − 4 + 4 = −10 + 4
5x = −6
Step 4: Divide both sides by 5.
5x / 5 = −6 / 5
x= −6 / 5
Answer:
x= −6 / 5

The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
