Answer:
The decimal place accuracy of a number is the number of digits to the right of the decimal point. The decimal point is a period written between the digits of a number. If there is no decimal point, it is understood to be after the last digit on the right and there is no place (zero place) accuracy.
The significant digits of a number are those digits that are most accurate. If a number has no place accuracy and there is no string of zeroes ending the number on the right, all the digits are significant. If a number has no place accuracy and there is a string of zeroes ending the number on the right, the significant digits are those digits to the left of the string of zeroes. If a number has a decimal point, the significant digits are the digits starting from the first non-zero number on the left to the last digit written at the right end. In either case the number of significant digits is just the count of these digits.
Decimal notation is the regular written format for a number. Scientific notation of a number just writes the significant digits followed by an appropriate power of ten.
The most common form of scientific notation inserts a decimal point after the first significant digit, follows the significant digits with times, "x", and then 10 to a power. If the original number is at least one, the power is the number of digits between the decimal point and the first number on the left. If the number is less than one, the power is the negative of the number of digits to the right of the decimal point up to and including the first non-zero number.
Calculators and computer software sometimes write scientific notation with the significant digits followed by the letter "E" and then the power of 10, without writing the base. A decimal point is usually inserted after the first significant digit.

translate FGH 3 units down and 2 units left followed by a rotation counterclockwise 90°.Then followed by a dilation by a scale factor of 2.
Step-by-step explanation:
Hope this helps, happy learning!!!
The diagram of translatation FGH 3 units down and 2 units left followed by a rotation counterclockwise 90° is attached below.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form.
Depending on the scale factor, the object's size can be raised or lowered.
The translate FGH 3 units down and 2 units left followed by a rotation counterclockwise 90°.Then followed by a dilation by a scale factor of 2.
F ( -1, 0)
G (1, 0)
H ( -1, 1)
Thus, counterclockwise 90°
F' ( 0, 1)
G' (0, -1)
H' ( -1, -1)
Scale factor = 2
Then
F'' ( 0, 2)
G'' (0, -2)
H'' ( -2, -2)
The diagram of translatation FGH 3 units down and 2 units left followed by a rotation counterclockwise 90° is attached below.

Answer:
#3- x=2.73
#4- x=8
Step-by-step explanation:
Answer: X = 3 / X = 8
Step-by-step explanation:
3. (Angles add up to 180)
30x + 4 + 86 = 180
30x + 90 = 180
subtract 90 from both sides
30x = 90
Now divide by 30
x = 3
Check your work ( input 3 to the equation)
30(3) + 4 + 84
90+ 90 = 180 it works :)
4. (Angles are adjacent to each other so there equal)
10x - 3 = 77
add 3 to both sides
10x = 80
divide it by 10
x = 8
Check your work ( input 8 to the equation )
10(8) -3 = 77
80 - 3 = 77
77 = 77

Jenna took a math test and answered 15 out of 20 answers correctly. What percent of the questions did she answer correctly?
Answer:
75%
Step-by-step explanation:
Answer:
75%
Step-by-step explanation:
15 x 5 75
---- = -------
20 x 5 100
Cent means 100, so percent literally means per 100 like in century or centennial. So, I put it into a fraction over 100. Now it is 75 per 100. If you remember, per 100 is percent, it means the answer id 75 percent. You can also write it as 75%.

Convert each mixed number to an improper fraction.
3 & 1/9 = 3 + 1/9
3 & 1/9 = 3*(9/9) + 1/9
3 & 1/9 = 27/9 + 1/9
3 & 1/9 = (27+1)/9
3 & 1/9 = 28/9
The car's average speed is 28/9 km per hour.
5 & 1/7 = 5 + 1/7
5 & 1/7 = 5*(7/7) + 1/7
5 & 1/7 = 35/7 + 1/7
5 & 1/7 = (35+1)/7
5 & 1/7 = 36/7
The time the car travels is 36/7 hours.
----------------------
We did the conversions so we can multiply the values easier.
Distance = Rate*Time
Distance = (28/9)*(36/7)
Distance = (28*36)/(9*7)
Distance = (4*7*9*4)/(9*7)
Distance = (4*4)/(1)
Distance = 16 kilometers
Justin is cooking dinner this week for his grandparents. He bought 1.5 pounds of green beans and 0.5 pounds of mushrooms to make a casserole. Green beans cost $2.20 per pound, and mushrooms cost $3.50 per pound. How much money did Justin spend in all?
Answer:
$5.05
Step-by-step explanation:
1.5*2.20 = 3.30
0.5*3.50 = 1.75
3.30 + 1.75 = 5.05

Answer:
61
Step-by-step explanation:
A triangle's total degrees is 180. You add the two angles they give you and then subtract the sum from 180. In number 9, the answer is 61. 47+72=119, 180-119= 61.
Write the equation for a line containing the point (0,2) and a slope of -7 (y=mx+b)
Answer:
[tex]y=-\frac{7}{1}x+2[/tex]
Step-by-step explanation:
The slope of -7=
[tex]-\frac{7}{1}[/tex]
so fractional slope is
[tex]y=mx+b[/tex]
Substituting slope into a fraction,
[tex]y=-\frac{7}{1} x+b[/tex]
Point is 0,2 so substitute in x and y.
[tex]2=-\frac{7}{1} (0)+b[/tex]
Solve the equation.
[tex]b=2[/tex]
So the equation for the line is
[tex]y=-\frac{7}{1}x+2[/tex]

Answer:
x=37
Step-by-step explanation:
You know all the angles in a triangle add up to 180.
Therefore, you add 72° and 71° which equals 143.
Then you subtract 180 and 143 which equals 36.
[72+71=143
180-143=37]

What is the slope of the line given, f(0) = -5 and f(4) = 11?
Answer:
The slope is 4.
Step-by-step explanation:
We are given that f(0)=-5 and f(4)=11.
This means that we have the two points (0, -5) and (4, 11).
So, we can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Let (0, -5) be (x₁, y₁) and let (4, 11) be (x₂, y₂). Substitute appropriately:
[tex]m=\frac{11-(-5)}{4-0}[/tex]
Evaluate:
[tex]m=\frac{16}{4}=4[/tex]
Hence, the slope of the line given f(0)=-5 and f(4)=11 is 4.

Which set of transformations would prove ΔQRS ~ ΔUTS?
Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
Reflect ΔUTS over y = 2, and translate ΔU′T′S′ by the rule (x − 2, y + 0).
Translate ΔUTS by the rule (x + 0, y + 6), and reflect ΔU′T′S′ over y = 6.
Translate ΔUTS by the rule (x − 2, y + 0), and reflect ΔU′T′S′ over y = 2.
Answer:
A
Step-by-step explanation:
The set of transformations would prove ΔQRS ~ ΔUTS is A. Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
Firstly, we need the general rotation method (x,y) to (-y,x)
So; U (-4,-2) becomes U’ (2,-4)
T(-2,0) becomes T’(0,-2)
S(-2,-2) becomes S’ (2,-2)
The set of transformations would prove ΔQRS ~ ΔUTS are;
Reflect ΔUTS over y = 2, and dilate ΔU′T′S′ by a scale factor of 2 from point S.
Thus, option A is correct.
