Peter has 5 books with 100 pages and 7 books with 10 pages. How many pages are in peter’s books?
Answer:
Hi, the answer would be that Peter has 570 pages in total.
Step-by-step explanation:
Since he has 5 books with 100 pages, you multiply 5 by 100
5 × 100 = 500
Next, Peter has 7 books with 10 pages each, so you multiply 7 by 10.
7 × 10 = 70
Next, you can add them together to get the total.
500 + 70 = 570
570 is the total.
Hope this helps!
570
Step-by-step explanation:
Because 5 multipled by 100 is 500
Then 7 multipled by 10 is 70
So 500+70=570

The area of the given doormat is 0.4 meter square.
Here, we are given that Sammy has a rectangular doormat. The dimensions of the doormat are given as follows-
The length of the doormat is = 4/5 meters
and the breadth of the doormat is = 1/2 meters
The area of a rectangular figure is given by the formula as follows-
Area of a rectangle = length × breadth
Let the area of the rectangular doormat be A
Thus, in this case, we have-
A = 4/5 × 1/2
A = 4/ 10
A = 2/5
Now, converting the area obtained into a decimal number we get-
A = 0.4
Thus, the area of the given doormat is 0.4 meter square.

Which equation represents a proportional relationship that has a constant of proportionality equal to 0.7?
Answer:
The usual representation of a proportional relationship is ...
y = kx
You want the constant of proportionality (k) to be 7/10, so this is ...
y = (7/10)x
Dividing by x gives the equivalent relationship ...
y/x = 7/10

Answer:
P(marks ≥ 20) = 0.4
Step-by-step explanation:
Marks gotten by the 5 students are;
15, 14, 20, 17, 25
Marks more than or equal to 20 are 2 in number namely 20 and 25.
Thus, probability of getting marks more than or equal to 20 is;
P(marks ≥ 20) = 2/5
P(marks ≥ 20) = 0.4

A used automobile dealership recently reduced the price of a used compact car by 12%. If the price of the car before discount was $34,500, find the new price.
A. 4,140
B. 36,640
C. 12,000
D. 30,360
Answer:
D
Step-by-step explanation:
The new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
A used automobile dealership recently reduced the price of a used compact car by 12%.
The price of the car before the discount = $34,500
The new price can be found using:
= 12% of $34,500
= (12/100)x34,500
= 0.12x34,500
The reduced amount = $4140
The new price = 34500 - 4140
The new price = $30,360
Thus, the new price of the used compact car is $30,360 if the used automobile dealership recently reduced the price of a used compact car by 12%.

Figure ABCD is a rhombus. Find the value of x.
The value of x is 32 degrees.
Rhombus
A rhombus is a special case of a parallelogram. In a rhombus, opposite sides are parallel and the opposite angles are equal. The rhombus is also called a diamond or rhombus diamond.
It is given in the question that there is a rhombus ABCD with ∠ DAC = 58 degrees.
We have to find the angle x or ∠ ADB.
We know the property that the diagonals of the rhombus perpendicularly bisect each other.
Hence, the rhombus is divided into 4 right triangles.
Hence,
∠DAC + ∠ADB = 180 - 90 = 90 degrees
58 + x = 90 degrees
x = 90 - 58
x = 32 degrees.

An election for favorite lunch snack is between Apples, Beets, and Carrots. Students voted for their top three from best to least. The results are: ABC : 41 BAC : 26 CAB : 42 How many votes will A have in total after B is eliminated due to the Hare method
Answer: after eliminating B due to Hare Method, A will have a total of 67 VOTES
Step-by-step explanation:
Given that;
The results are
ABC : 41
BAC : 26
CAB : 42
NOW
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
C>A>B = 42 ⇒ C has 42 votes
According to Hare method, least votes gainers will be eliminated and once eliminated, his/her/its votes will be transferred to the next choice of person/thing.
based on the question; B will be eliminated
so we have;
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
we eliminate B, the votes are transferred to the next (A)
A>C = 26 ⇒ A has 26 votes
C>A>B = 42 ⇒ C has 42 votes
SO in total
A votes = 41 + 26 = 67 VOTES
Therefore after eliminating B due to Hare Method, A will have a total of 67 VOTES
After eliminating B due to Hare Method, A will have a total of 67 votes
We have given that,the results are
ABC : 41

CAB : 42
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
C>A>B = 42 ⇒ C has 42 votes
What is the Hare method?
The Hare method is least votes gainers will be eliminated and once eliminated,The votes will be transferred to the next choice of person/thing.
From the given question we have B will be eliminated
Therefore we have
A>B>C = 41 ⇒ A has 41 votes
B>A>C = 26 ⇒ B has 26 votes
We eliminate B, the votes are transferred to the next (A)
A>C = 26 ⇒ A has 26 votes
C>A>B = 42 ⇒ C has 42 votes

what equation is equal to the x axis x = 4, x +y = o, x = y, y = 4
The x-axis is equivalent to x = 4, x + y = 0, x = y, and y = 4, and the value of the x-axis is y = 0.
What is equivalent?Expressions that are equivalent do the same thing even when they have distinct appearances.. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s)
The Cartesian plane is what?A coordinate system is a plane with Cartesian coordinates. Each point is uniquely identified by a pair of numerical coordinates that are the signed distances from two fixed perpendicularly oriented lines to the point, measured in the same unit of length.Given that all of the y-values on the x-axis are zero, the x-axis' equation is y = 0.Similar to the x-axis, the y-axis also has all zero values, therefore the equation of the y-axis is x = 0.((This presupposes that we're referring to the Cartesian plane, i.e. we are limiting ourselves to two dimensions.)

If y is directly proportional to x and y =1200 when x=30, then what is the value of x when y=30?
Answer:
Y= 30
X= 0.75
Step-by-step explanation:
If the first Y was 1,200 and X was 30, then that means every time your divide Y by 40, you will get your X. It's the exact opposite if you want to find Y.
So you want to divide your Y, which is 30, by 40. Once who find your answer, you should have gotten 0.75 for X.
Why divide by 40? Good question. You divide by 40 because if you multiply your X example Y= 1,200, X= 30, you will get 30x40 which is 1,200. Do it the other way around divide 1,200 by 40, you get 30.
All in all your answer should be X= 0.75. If not tell me.

What is the value of x, y, z? Please answer need help soon
Answer:
x = 55
y = 55
z = 70
Step-by-step explanation:
x + 125 is a straight line, 180⁰ x+125=180 x=55⁰
since this is an isosceles triangle, x = z
and the sum of all angles in any triangle is 180⁰
55+55+y=180⁰
y = 70⁰
Answer:
x=55º, y=70º, z=55º
Step-by-step explanation:
We have that xº = 180º - 125º = 55º
As it is an isosceles triangle, we have xº = zº = 55º
Therefore, yº = 180º - (xº + zº) = 180º - (55º + 55º) = 180º - 110º = 70º
