Answer:
1 significant figure
Step-by-step explanation:
Zero is significant when:
It occurs between two non-zero integers, such as 408; it occurs at the end of a number that contains a decimal point, such as 570. or 1.300
Zero is not significant when:
It is before the first non-zero integer, such as 0.0057 (two significant figures); it is at the end of a number that does not contains a decimal point, such as 253,000 (three significant figures)

The third angle of 16 degrees and 102 degrees is 62 degrees.
The third angle of 119 degrees and 23 degrees is 38 degrees.
The third angle of 28 degrees and 87 degrees is 65 degrees.
The third angle of 96 degrees and 51 degrees is 33 degrees.
What is the third angle?A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
In order to determine the missing angle, subtract the sum of the two given angles from 180.
180 - (16 + 102) = 62
180 - (119 + 23) = 38
180 - (28 + 87) = 65
180 - (96 + 51) = 33

g(-6) = -6
g(0) = 5
g(7) = 8
h(-6) = 10
h(0) = -1
h(7) = -4
Step-by-step explanation:
g(x) = (1/3) f(x)
g(-6) = (1/3)(-18) = -6
g(0) = (1/3)(15) = 5
g(7) = (1/3) (24) = 8
h(x) = -g (x) + 4
h(-6) = -(-6) + 4 = 10

Suppose the equation for line A is y = 6/5 x - 10 Line A is parallel to line B, which is perpendicular to line C. If line D is perpendicular to line C and perpendicular to line E, what is the slope of line E? Justify your conclusion.
If slopes of the given lines are solved and observed, we get the slope of line E is [tex]m_{E}[/tex] = [tex]\frac{-5}{6}[/tex]
As per question statement, the equation for line A is [tex]y = \frac{6x}{5} - 10[/tex] Line A is parallel to line B, which is perpendicular to line C. The line D is perpendicular to line C and perpendicular to line E.
Before solving this question, we need to know about some basic formulas and concepts of equation for a line.
If Lines are parallel, their slopes are equal and if lines are perpendicular, the product of their slopes is -1.
i.e., if [tex]m_{1}[/tex] and [tex]m_{2}[/tex] are slopes of two lines then if,
[tex]m_{1} = m_{2}[/tex] then lines are parallel
Now slope of line A can be found out by formula [tex]y=mx+c[/tex] hence slope of line A [tex]m_{A}[/tex]= [tex]\frac{6}{5}[/tex]
Line B is parallel to A so, [tex]m_{B}[/tex] = [tex]\frac{6}{5}[/tex]
Line C is perpendicular to B so [tex]m_{C} * m_{B} = -1\\m_{C} = \frac{-5}{6}[/tex]
Line D is perpendicular to C so [tex]m_{D} *m_{C} = -1\\m_{D} = \frac{6}{5}[/tex]
Line E is perpendicular to D hence [tex]m_{E} * m_{D} = -1\\m_{E} = \frac{-5}{6}[/tex]
Therefore the slope of line E is [tex]\frac{-5}{6}[/tex]

Sinita has more than what she needs, so yes Sinita has enough nails. (144>140)
If f(x) = -x³, g(x) = 3x² - 1, and h(x) = 2x + 5, what is the degree of [f o go h](x)?

The degree of the polynomial formed is 6.
The degree of a polynomial is the highest degree of the variables present with non-zero coefficients.
For example the polynomial has three 7x³y²+9xy+4 terms. The first term has a degree of 5 (the sum of the powers 2 and 3), the second term has a degree of 1, and the last term has a degree of 0. Therefore, the polynomial has a degree of 5, which is the highest degree of any term.
Now the given functions are:
[tex]f(x)=x^3[/tex] ,g(x)=3x²-1 and h(x)=2x
Now we have to find (f ° g° h)(x). Let us first find (g°h)(x).
(g°h)(x) is equal to g[h(x)]
=g[2x+5]
=3(2x+5)²-1
=3(4x²+20x+25)-1
=12x²+60x+74
Now we find (f ° g° h)(x)
(f ° g° h)(x)=f[g(2x+5)]
f[g(2x+5)]=f(12x²+60x+74)
f(12x²+60x+74)=(12x²+60x+74)³
Now we have to simplify the expression:
(12x²+60x+74)³
=[tex]1728x^6+25920x^5+161568x^4+535680x^3+996336x^2+985680x+405224[/tex]

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 6 liters of natural oil for every 5 liters of synthetic oil. In order to make 671 liters of Petrolyn oil, how many liters of natural oil are needed?
According to the given statement,
366 liters of natural oil is needed to make 671 L synthetic oil.
What is Synthetic Oil?
Essential oils, which are more natural, are slightly different from synthetic oils. An intentionally created chemical component is present in synthetic oils, which are used as lubricants.
Full synthetics and semi-synthetic oils are the two primary types of synthetic oils. Full synthetics originate from crude oil or byproducts in this situation. Conventional oils are produced using chemical procedures rather than distillation. The resulting synthetic oil has a higher molecular make-up and frequently exhibits more consistent characteristics. Synthetic oils are used in many cosmetic and medicinal goods, just like their more natural equivalents.
According to the given values;
The ratio of natural to synthetic oil
= 6:5
If 671 liters have to be made then,
Add 6+5=11
So, 6/11 of 671liters will be = 366 liters of natural oil
and, 5/11 of 671 liters will be = 305 liters of synthetic oil

a persian rug has a width of 9.00 feet and a length of 12.0 feet. what is the area of this rug in m2? (there are exactly 2.54 cm in one inch.)
The area of a persian rug in a metre square is given by 10.03 m2. It is calculated by using the concept of area and conversion of units of a quantity.
What is the conversion of units?
Conversion of units is the transformation between various units of measurement for the same quantity, simply the conversion of units deals with converting a quantity into different units without changing its magnitude.
Calculation of the area of the persian rug with given width and length
Given:
Length = 12 feet
Width = 9 feet
The basic step involved in solving this problem is to convert the length and width given in feet into metre
We know that 1 feet = 0.3048 m
Length = 12 × 0.3048
= 3.657 m
Width = 9 × 0.3048
= 2.743 m
Area of rug = length × width
= 3.657 × 2.743
= 10.03 m2
Hence, the required area of the persian rug is 10.03 m2.

It is not possible that the intersection case is P(A B)=0.5 .
What is intersection?The set of all objects that are members of both sets A and B is represented by the intersection of the two sets A and B, abbreviated as A∩B.
If there is any element x that is an element of both A and B, then we can also say that A intersects (meets) B at x. If A∩B is an inhabited set, which means that there must be some x such that x∈A∩B exists, then A intersects B equivalently.
If A does not intersect B, then A and B are said to be disjoint. They share no elements, to put it simply. If the intersection of A and B contains nothing—A∩B=Ф—then A and B are disjoint.
Explanation:
The likelihood of occurring of an event is called probability.
Consider two events A and B are occurred with probabilities P(A) and P(B) respectively.
The probability that both the events occurs is,
P(A and B)=P(A∩B)
When both the events are independent,
P(A and B)=P(AB) = P(A)x P(B)
The probability that either A or B occurs is,
P(A or B)= P(AUB) = P(A)+P(B)-P(A∩B)
When both the events are mutually exclusive the probability that either A or B occurs is,
P(A or B)=P(AUB) = P(A)+P(B)
The compliment of the probability is,
P(A)=1-P(A)
The conditional probability of occurring of an event A when it is given that B had already occurred is,
P(A|B)=P(A∩B)/P(B)
Let A represent the situation where the chosen person has a Visa credit card and B represent the situation where they have a Master card. The probability of occurring event A is 0.6 and the probability of occurring event B is 0.4 that is, P(A)=0.6, P(B)=0.4 .
It is known that P(A B)∠P(A) and P(A B)∠P(B) . So, it is not possible that the intersection case, P(A B)=0.5 .

What is the equation of the line that passes through the point (-6,-3) and has a slope of -1/6?
Answer:
y = (-1/6)x - 4
Step-by-step explanation:
Line equations are usually expressed in the following format:
y = mx + c
Where m is the gradient (slope), and c is the y-intercept.
We can fill in the value of m right away as we are given it in the question:
y = (-1/6)x + c
And we are given the point (-6,-3), so we can fill in the values for x and y, in order to find the value of c:
-3 = (-1/6)(-6) + c
Rearrange and simplify this:
-3 = 1 + c
c = -4
Finally, substitute the value of c back into the original equation to get the final equation of the line:
y = (-1/6)x - 4

Discounts are price reductions that store owners make on items or services that are otherwise priced as marked. This portion of the refund is typically provided to boost sales or get rid of excess inventory. The price of an item as stated by the manufacturer or seller, without any price decrease, is known as the List price or Marked Price. After any discounts or price reductions from the list price, the selling price is the final price at which an item is actually sold. Discounts are sometimes referred to as "off" or "reductions."
