There are 52 weeks in one year. If cindy drew three pictures each week, for 2 years, how many pictures did cindy draw?
Final answer:
Cindy drew a total of 312 pictures over two years, calculating from three pictures per week for 52 weeks each year, then doubling the result for the two years.
Explanation:
To calculate the total number of pictures Cindy drew over two years, we start by determining the number of pictures she draws each week.
Since Cindy draws three pictures each week, we multiply that number by the number of weeks in one year.
There are 52 weeks in one year.
So, the number of pictures Cindy draws in one year is:
3 pictures/week × 52 weeks/year = 156 pictures/yearSince the question is about a two-year period, we multiply the annual amount of pictures by two:
156 pictures/year × 2 years = 312 picturesTherefore, Cindy drew a total of 312 pictures over two years.

Answer: Orlando mixed five pounds of cereal squares and 25 pounds of nuts.
Answer:
5 lbs cereal squares.
25 Ibs nuts.
Step-by-step explanation:
Let x be the weight of nuts in pounds and y be the weight of cereal squares in pounds.
Total weight of the party mix is 30 pounds.
[tex]x+y=30[/tex] ..... (1)
It is given that,
Cost of nuts = $7 per pound
Cost of cereal = $4 per pound
The cost of mix = $6.50 per pound.
[tex]7x+4y=6.50\times 30[/tex]
[tex]7x+4y=195[/tex] ..... (2)
Substitute the value of x in equation (2) from equation (1).
[tex]7(30-y)+4y=195[/tex]
[tex]210-7y+4y=195[/tex]
[tex]-3y=195-210[/tex]
[tex]-3y=-15[/tex]
Divide both sides by -3.
[tex]y=5[/tex]
Substitute y=5 in equation (1).
[tex]x+5=30[/tex]
Subtract both sides by 5.
[tex]x=30-5[/tex]
[tex]x=25[/tex]
Therefore, he use 25 lbs of nuts and 5 lbs cereal squares for party mix.
A rectangle has an area of 90 square centimeters and a height of 12.5 centimeters. What is the length of the base?
A.
7.2 centimeters
B.
72 centimeters
C.
112.5 centimeters
D.
1125 centimeters
Answer:
A. 7.2 centimeters
Step-by-step explanation:
The length of the base is 7.2 centimeters. The area of a rectangle is length*width
The length is unknown but the area is known. To find the length, all we have to do is divide the area from the height.
The working is as follows :
Area = 90 cm²
Height = 12.5 cm
Length = ?
Length = Area ÷ Height
= 90 ÷ 12.5
= 7.2cm
The length of the base of the rectangle is found by dividing the area by the height, which gives 7.2 centimeters.
Explanation:The subject is about finding the length of the base of a rectangle given its area and height. The formula to find the area of a rectangle is Area = Length x Width. From the question, we know the Area is 90 square centimeters and the height (which can also be considered as the Width) is 12.5 centimeters. Therefore, we can arrange the formula to solve for Length: Length = Area / Width.
Substituting the given numerical values we find: Length = 90 / 12.5 = 7.2 centimeters. So, the correct answer is 7.2 centimeters (Option A).

What is 6.02 nearest tenth
Answer:
6
Step-by-step explanation:
The digit in the hundredth place value of 6.02 is 2, so it rounds down.
The number 6.02, when rounded to the nearest tenth, results in 6.0, as '2' in the hundredths place is less than '5' and requires rounding down.
Explanation:Given the number 6.02, rounding to the nearest tenth means identifying what tenth it is closest to. The number in the tenths place is '0'. For rounding, we look at the digit following the tenths place, which is the hundredths place. Here, the number is '2'. If this number is 5 or more, we round up. If it's 4 or less, we round down. So, 6.02 to the nearest tenth, would be 6.0 because 2 is less than 5, so we round down.

If f(x) = х2 – 2x and g(x) = 6х +4, for which vаluе оf x does (f + g)(x) = 0?
Answer:
x = - 2
Step-by-step explanation:
(f + g)(x) = f(x) + g(x)
f(x) + g(x) = x² - 2x + 6x + 4 = x² + 4x + 4
Equating to zero, that is
x² + 4x + 4 = 0 ← left side is a perfect square

The given line passes through the points (0, ) and (2, 3). On a coordinate plane, a line goes through (0, negative 3) and (2, 3). A point is at (negative 1, negative 1). What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point ()?
Option 2 is correct.
[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]
To find the equation of a line that is parallel to the given line and passes through the point (-2, 2), we follow these steps:
1. Determine the slope of the given line. Parallel lines have the same slope.
2. Use the point-slope form of a line equation with the given point and the determined slope to find the equation of the parallel line.
From the graph, we can see that the given line passes through points (0, -3) and (-5, -4). To find the slope (m) of the line, we use the slope formula:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]
Substituting the given points, we get:
[tex]\[ m = \frac{-4 - (-3)}{-5 - 0} \][/tex]
[tex]\[ m = \frac{-4 + 3}{-5} \][/tex]
[tex]\[ m = \frac{-1}{-5} \][/tex]
[tex]\[ m = \frac{1}{5} \][/tex]
Now we have the slope of the parallel line, which is[tex]\( \frac{1}{5} \)[/tex]. The point-slope form of the line equation is [tex]\( y - y_1 = m(x - x_1) \)[/tex]. Plugging in the slope and the point (-2, 2), we get:
[tex]\[ y - 2 = \frac{1}{5}(x - (-2)) \][/tex]
[tex]\[ y - 2 = \frac{1}{5}(x + 2) \][/tex]
Now we simplify and solve for y to put it in slope-intercept form ( y = mx + b ):
[tex]\[ y - 2 = \frac{1}{5}x + \frac{2}{5} \][/tex]
[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + 2 \][/tex]
[tex]\[ y = \frac{1}{5}x + \frac{2}{5} + \frac{10}{5} \][/tex]
[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]
So the equation of the line that is parallel to the given line and passes through the point (-2, 2) is:
[tex]\[ y = \frac{1}{5}x + \frac{12}{5} \][/tex]
Which ordered pair is a solution to the linear system? (2x + y = 5) (x – y = 13)
Answer:
The solution is {6, -7}.
Step-by-step explanation:
2x + y = 5
x – y = 13 Adding these 2 equations eliminates y:
3x + 0 = 18
x = 6.
Substituting for x in equation (1):
2(6) + y = 5
y = 5 - 12 = -7.
The ordered pair that is a solution to the linear system of equations, (2x + y = 5) and (x - y = 13), is (6, -7). The solution was found by using the elimination method.
Explanation:You can solve this linear system by using the substitution or elimination method. Here, I will use the elimination method, which involves adding or subtracting the equations to eliminate one of the variables.
First, add the two equations together. (2x + y) + (x – y) equals 5 + 13. This simplifies to 3x = 18. Second, divide both sides of the equation by 3 to solve for x. This gives x = 6. Substitute this value back into either of the original equations. By substituting into the first equation, it becomes 2*6 + y = 5. Simplifying it, gives y = -7.So the
ordered
pair that is a solution to the linear system is (6, -7).

Mary weighs n kg while her sister weighs 15 kg less. How many times is Mary heavier than her sister?
For this case we have to:
n: Represents the weight of Mary in Kg.
If your sister weighs 15 kg less we have:
[tex]y = n-15[/tex]
Where "y" represents the weight of his sister in kg.
To find how many times Mary is heavier than her sister, we must divide Mary's weight by her sister's weight.
We have then:
[tex]N= \frac{n}{n-15}[/tex]
Answer:
Mary is [tex]N= \frac{n}{n-15}[/tex] times heavier than her sister.
Answer:
Mary weighs[tex]\frac{n}{(n-15)}[/tex]heavier than her sister.
Explanation:
As we have given the data in the question that
Weight of marry = n kg
Weight of Marry sister = n-15 kg
Let Marry be ‘K' times heavier than her sister then it means that
K=[tex]\frac{n}{(n-15)}[/tex]
And we can write the above equation as
K(n-15) = n
K=[tex]\frac{n}{(n-15)}[/tex]
which completely explains the above statement that Weight of the marry is K times the weight of her sister.
So the correct answer is K=[tex]\frac{n}{(n-15)}[/tex]
