Answer:
5.87 x [tex]10^{-17}[/tex]
Step-by-step explanation:
You need to write the number as 1 or larger than 1, but less than 10. That means that I need to put the decimal between the 5 and the 8. Now I have to count how many places I moved the decimal. I think that I counted right. It was moved 17 places. Since the number in standard form is much smaller than 5.87, the exponent will be negative.

ABC is a triangle.
ADC is a straight line with BD perpendicular to AC.
AB = 8 cm
BC = 12 cm
Angle ABD = 60.
Calculate the length of DC.
Give your answer to 3 significant figures
The length of segment DC is given by the law of sines and trigonometric ratios as approximately 11.3 cm
What is the law of sines?The law of sines states that in a triangle, the ratio of the sine of an interior angle of a triangle to the length of the side opposite the angle is constant.
The given parameters are;
The figure ABC is a triangle
The figure ADC is a straight line segment
Segment BD is perpendicular to segment AC
The length of segment AB = 8 cm
Length of segment BC = 12 cm
The measure
[tex] \angle ABD = 60^{ \circ} [/tex]
Required;
The length of segment DC
Solution;
[tex] \angle ADB = 90^{ \circ} [/tex]
Definition of segment BD being perpendicular to segment AC
[tex] \angle BAC = 90^{ \circ} - 60^{ \circ} = 30^{ \circ}[/tex]
Using the law of sines, we have;
[tex]AD = AB × sin( \angle ABD) [/tex]
A vertex of the triangle from the question is point B
Which gives;
AD = 8 × sin(60°) = 4•√3
Similarly, from the law of sines, we have;
[tex]\displaystyle{\frac{BC}{sin ( \angle BAC)} = \frac{AB}{sin ( \angle BCA)} } [/tex]
Which gives;
[tex] \displaystyle{\frac{12}{sin ( 30^{ \circ})} = \frac{8}{sin ( \angle BCA)} } [/tex]
[tex] \displaystyle{ sin ( \angle BCA) = \frac{sin ( 30^{ \circ}) \times 8}{12}= \frac{1}{3} }[/tex]
[tex] \displaystyle{ \angle BCA = arcsine \left(\frac{1}{3}\right) }[/tex]
[tex] \displaystyle{DC= 12 \times cos\left(arcsine \left(\frac{1}{3}\right)\right) = 8\cdot \sqrt{2}}[/tex]
Therefore, DC = 8•√2 ≈ 11.3

Total of 10 and $ total of $0.85. The place value denotes a word, whereas the total value denotes a figure. In mathematics, ten numbers are known as symbols or digits.
What is meant by Summation?The sum of the digit and its place value is the total value. Example 1: In the number 58439, what is the place value of digit 4? As a result, digit 4's place value is Hundreds. Market capitalization is the value of a company as determined by the stock market. It is defined as the sum of all outstanding shares' market values. Multiply the number of outstanding shares by the current market value of one share to calculate a company's market cap.
Therefore,
a # total of 10
a $ total of $0.85
· Since we have 2 unknowns, we need to set up a System of 2 Equations.
· A System of 2 Equations helps us solve a situation with 2 Unknowns.
Let's set up our 2 equations for # and $.
· For the # equation:
Let n = # of nickels
Let d = # of dimes
So, n + d = 10
· For the $ equation, we have to assign a "value" to each of the coins:
A nickel is worth 5 cents or $0.05
A dime is worth 10 cents or $0.10
· They told us we have 5 cents, a specific # of times + 10 cents, a certain # of times, that = $0.85
So, $0.05n + $0.10d
= $0.85
To solve this, we have to have just 1 unknown, meaning just 1 variable.
· We represent one of the variables in terms of the other. But, which one?
· Well, since they are asking for # of dimes, let's define a nickel in the duration of a dime.
· Let's apply this in the simpler # equation:
So, n + d = 10
becomes n = 10 - d
· So now, in our $ equation, we can just replace "n" with "10 - d", and then solve for d, which is the # of dimes!
$0.05n + $0.10d = $0.85
$0.05(10-d) + $0.10d = $0.85
$0.5 - $0.05d + $0.10d = $0.85
$0.50 + $0.05d = $0.85
$0.05d = $0.35
d = 7
Check this with the # equation:
n + d = 10
n + 7 = 10
n = 3
Does that make sense? Let's see:
3 nickels + 7 dimes = $0.85 ?
3($0.05) + 7($0.10) = $0.85
$0.15 + $0.70 = $0.85
$0.85 = $0.85

Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies. Each box of chocolate chip cookies has 36 cookies. Each box of sugar cookies has 84 cookies. Mia says she has about 1,800 cookies in all. Is her answer reasonable? Explain.
Yes, because (12 x 20) + (40 x 80) = 3,400
Yes, because (12 x 80) + (40 x 40) = 2,560
No, because (12 x 40) + (20 x 80) = 2,080
No, because (12 x 80) + (20 x 40) = 1,760
Answer:
The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.
Step-by-step explanation:
Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.
Each box of chocolate chip cookies has 36 cookies.
Each box of sugar cookies has 84 cookies.
So, the total number of chocolate chips cookies will be = 12 * 36 ----(i)
And the total number of sugar cookies will be = 24 * 84 -----(ii)
As Mia says she has about 1,800 cookies in all.
So, we can write (i) and (ii) combined as,
(12*36) + (24*84) = 1800
The answer given by Mia is not reasonable cause, when we sum up the data given by her we will conclude that the expression should be like (12*36) + (24*84) = 1800.
Explanation: No, her answer is not reasonable.
Step by Step solution:
According to the given information, Mia has 12 boxes of chocolate chip cookies and 24 boxes of sugar cookies.
Now, each box of chocolate chip cookies has 36 cookies which means she has (36 × 12) = 432 chocolate chip cookies in total, using the unitary method.
Also, each box of sugar cookies has 84 cookies which means she has (84 × 24) = 1008 sugar cookies in total, using the unitary method.
Mia will then have with her in total of [(36 × 12) + (84 × 24)] = 1440 cookies.
It is an incorrect fact that Mia says that she has about 1800 cookies in total.
Hence, Mia has 1440 cookies in total.

f(x) = -8x + 20; 5 – 2[f(-1)]
The value of the function at the given value of x = -1 is 5 - 2[f(-1)] = -51
How to evaluate the function at the given value?The equation of the function is given as
f(x) = -8x + 20
The function to calculate is given as
5 - 2[f(-1)]
So, we start by calculating the value of the function at x = -1
This is represented as 'f(-1)
So, we have the following equation
f(-1) = -8(-1) + 20
Evaluate the product
So, we have the following equation
f(-1) = 8 + 20
Evaluate the sum
So, we have the following equation
f(-1) = 28
Substitute f(-1) = 28 in the expression 5 - 2[f(-1)]
So, we have
5 - 2[f(-1)] = 5 - 2 x 28
Evaluate the product
5 - 2[f(-1)] = 5 - 56
Evaluate the difference
5 - 2[f(-1)] = -51
Hence, the value is -51

At a plant, 160,000 tons of petrochemicals are required to produce 100,000 tons of plastic. how many tons of petrochemicals are required to produce 5,000 tons of plastic?
Through the unitary method, we get that 8000 tons of petrochemicals are required to produce 5,000 tons of plastic.
A problem can be solved using the unitary method by first determining the value of a single unit, and then multiplying that value to determine the required value.
Given :
160,000 tons of petrochemicals are required to produce 100,000 tons of plastic.
160,000 tons of petrochemicals produces = 100,000 tons of plastic.
To produce 1 ton of plastic, the required amount of petrochemicals = [tex]\frac{160,000}{100,000} = \frac{8}{5}[/tex] tons...........equation (1)
Let x be the tons of petrochemicals required to produce 5,000 tons of plastic.

Let's consider a quadrilateral ABCD which is a parallelogram with AC as its diagonal.
We know, in parallelograms opposites' sides are parallel.
So, AB∥DC and AD∥BC
Since AB is parallel to DC and AC is the transversal.
By alternate angles,
∠BAC = ∠DCA
y = a -----------------(1)
Similarly, AD is parallel to BC and AC is the transversal.
The alternate angles,
∠DAC = ∠BCA
x = b -----------------(2)
Adding equations ( 1 ) and ( 2 ),
∠BAC + ∠DAC = ∠DCA + ∠BCA
∠BAD = ∠DCB
x + y = a + b
Similarly, we can prove, ∠ADC=∠ABC
Hence proved, opposite sites of a parallelogram are equal.

Select EACH correct answer.
A. Horizontal translation 1 units right.
B. Horizontal translation 3 units right.
C. Vertical translation 3 units down.
D. Vertical translation 1 unit down.
E. Horizontal translation 1 unit left.
F. Vertical translation 3 units up.
We can see that function g(x) is a translation of one unit to the left and 3 units downwards of f(x), thus, the correct options are:
C and E.
What transformations are applied to the function f(x)?Here we have the two functions:
f(x)
g(x) = 4^(x + 1) - 3
And we know that g(x) is a translation of f(x)
Remember that the translations works as follows:
Vertical translation of N units:
g(x) = f(x) + N
If N > 0, the translation is upwards.
If N < 0, the translation is downwards.
Horizontall translation of N units:
g(x) = f(x) + N
If N > 0, the translation is to the left
If N < 0, the translation is to the right.
In this case, we can write g(x) as:
g(x) = f(x + 1) - 3 = 4^(x + 1) - 3
So we will have a translation of one unit to the left and 3 units downwards.
