Answer:
Step-by-step explanation:
This expression involves the distributive property. In the distributive property, there is a number followed by an equation in parenthesis.
3(n+6)
To simplify it, you have to multiply the first number by each number in the parenthesis, separately:
3(n+6)
3n + 3(6) or 3xn + 3x6 (same thing)
3n+18
Finally, we can check the other 4 choices to double check.
A. 3n+6 (wrong)
B. 2(n+6) + (n+6)=
2xn + 2x6 + n + 6
2n + 12 + n + 6
combine like terms, or all the terms that are the same. start with the Ns, then the numbers:
2n+n + 12+6
3n+18
C. 2(n+6)+n= 2n+2(6) +n = 2n+12+n= 2n+n+12= 3n+12
D.3n+18
E. 2n+2+n+4= 2n+n+2+4= 3n+6
Answer= B and D

Is Figure B a scale copy of Figure A?
Yes, the Figure B is a scale copy of Figure A.
Given that are two figures we need to see if the Figure B a scale copy of Figure A or not.
To determine if Figure B is a scale copy of Figure A, we need to compare the two figures and check if they have the same shape but differ in size. A scale copy means that Figure B is an enlarged or reduced version of Figure A, but the proportions and shape of the two figures remain the same.
We see the side lengths of Figure A are: 6 units, 3 units, 3 units, 3 units, 6 units.
And that of Figure B are: 2 units, 1 unit, 1 unit, 1 unit, 2 units.
Taking the ratio = 6/2 = 3/1 = 3/1 = 3/1 = 6/2 = 3
So, it is clear that the side lengths are in equal proportion.
Hence the Figure B is a scale copy of Figure A.

a two digit number has three times as many tens than ones. The difference between the number and twice the reversed number is 15.Find the number
olution

Verified by Toppr
Let the one's digit be y and tens digit be x,
Number = 10x + y
Then,x=3y⋯(i)
Reversed number = 10y + x
A.t.Q :- (10x+y)−(10y+x)=36 Put x = 3y in eq. (i)
⇒9x−9y=36
⇒x−y=4⋯(ii)
⇒3y−y=4
∴2y=4 x=3y ∴x=6
y=2
∴ Number = 62
The base of an isosceles triangle is three times as long as the side of a square. Each leg of the triangle is 1 inch more than twice a side of the square. Find the length of a leg of the triangle if the sum of perimeters is 46 inches.
9 inches
Step-by-step explanation:Let x be the length of the side of the square.
If the base of the triangle is 3 times as long as the side of the square, it is 3 times x, or 3x.
The same can be said for the legs, which is 1 inch more than twice the side of the square, so 2x + 1.
The triangle can therefore be thought to look like the triangle below.
The perimeter is therefore (2x+1) + (2x+1) + 3x, which is 7x + 2.
The sum of perimeters of both the square and triangle is 46.
The perimeter of the square is 4x, so the sum of perimeters is 4x + (7x+2), or 11x + 2.
11x + 2 = 46, so 11x = 44.
x is therefore 4
The leg is 2x + 1, so the leg is 8 + 1, so the length of the leg is 9 inches.

One dozen students each drop a brass tack six times from a height of six inches onto a level hard surface. They record the number of times the tack lands point up. The table below lists their results.

What was the experimental probability that the tack lands point-up for student 7?
0.800
0.833
0.200
Answer:
0.833
Step-by-step explanation:
1. locate which vertical column of the graph we are referring to:
student 72. calculate the total number of trials student 7 did:
if in 5 trials the tack landed point-up, and in 1 trial the tack did not land point-up, the total number of trials is 65 + 1 = 63. refer back to the question:
the question states: "what is the experimental probability that the tack lands point-up"4. interpret the graph:
of the 6 trials student 7 underwent, the graph tells us that 5 landed point-up. therefore the experimental probability of a tack landing point up is 5/6 (in 5 out of the 6 trials, the tack landed point-up)5. converting from fraction to decimal:
all the given answers are given in decimal form, whilst our current answer (5/6) is in fraction form. to convert to decimal form, simply divide the top number by the bottom number5 ÷ 6 = 0.833therefore, the experimental probability that the tack will land point-up, is 0.833

Find the acute angle between two diagonals of quadrilateral ABCD if it is known that AB=BC=CD and AC=BD=AD.
Answer:
45⁰
Step-by-step explanation:
The quadrilateral ABCD is a square.
Since the question stated that all the sides are equal. (AB=BC=CD)
It also stated that the diagnonals are equal. (AC=BD=AD)
I wish I could draw to explain this easily
A square has four right angles.
A right angle is a 90⁰ angle.
The diagonals divide each 90⁰ angle by 2
I hope you know what a diagonal is.
It is a line from a corner of the square to the opposite corner. This cuts the square into two equal sides.
After drawing the first diagonal two triangles of equal size will be seen.
After drawing the second diagonal the two triangles that appeared will each be cut into halves.
Now, you'll have four equal triangles.

How are the pieces of a step function related to the domain of the function? Justify your thinking.
Step-by-step explanation:
As we know, for any function domain is referred to as the set of input values that can be taken for an independent variable in the given function. Range of a function is defined as the set of output values generated for the domain (input values) of the function. In the case of a step function, for each value of x, f(x) takes the value of the greatest integer, less than or equal to x. For example:
[-2.19] = -3
[3.67] = 3
[-0.83] = -1
The domain of this function is a group of real numbers that are divided into intervals such as [-5, 3), [-4, 2), [-3, 1), [-2, 0) and so on. This explains the domain and range relations of a step function.
This can be generalized as given below:
[x] = -2, -2 ≤ x < -1
[x] = -1, -1 ≤ x < 0
[x] = 0, 0 ≤ x < 1
[x] = 1, 1 ≤ x < 2

Answer:
Step-by-step explanation:
n(U)=100%
n(S)=70%
n(W)=15%
n(S union w compliment)=20%
n(s intersection W)=?
n(u)=n(s)+ n(w)+ n(s union w compliment)- n(s intersection w)
or 100%=70% +15%+ 20% - n( s intersection w)
or 100%= 95%- n(s intersection w)
or 100%-95%=n(s intersection w)
or 5%= n( s intersection w)
now;
n(only w)=n(w)- n(s intersection w)
=15%- 5%
=10%
10%of people only like winter season.
i think the question is to find people who only like winter season.
if not then ans is 15% according to question.
a) The illustration of the given information in a Venn diagram is attached.
b) The percentage of people who liked both seasons is 45%.
c) If 180 people liked the summer season only, proportionately, the number of people who liked the winter season only is 300.
How the Venn diagram is illustrated:The Venn diagram, which shows similarities and contrasts, can be illustrated based on the given percentages.
Percentages are one of the ways to depict proportions, which are the equation of two ratios.
The percentage of survey people who liked the summer season = 60%
The percentage of survey people who liked the winter season = 70%
The percentage of survey people who liked none of the seasons = 15%
The percentage of participants who liked one of the seasons = 85% (100% - 15%)
The total percentage of survey people who liked either summer or winter = 130% (60% + 70%)
b) The percentage of survey people who liked both seasons = 45% (130% - 85%)
The percentage that liked only summer = 15% (60% - 45%)
The percentage that liked only winter = 25% (70% - 45%)
c) 180 people liked summer only
180 = 15%
Proportionately, if 180 = 15% of the people, the total number of people = 1,200 (180/15%)
The number of people who liked winter season only = 300 (1,200 x 25%)
