2. At the gym, Alex spends 24 minutes doing
resistance training for every 30 minutes
spent doing cardio exercises, Carisa spends
15 minutes on resistance for every
20 minutes on cardio, and Manuel spends
14 minutes on resistance for every
15 minutes on cardio. Which person has the
greatest ratio of minutes spent on resistance
to minutes spent on cardio? (Example 2)
Alex
Resistance (min)
Cardio (min)
Carisa
Resistance (min)
Cardio (min)
Manuel
Resistance (min)
Cardio (min)
Answer:
Manuel
Step-by-step explanation:
You should set up a proportion graph first such as r:c where r is the amount of minutes spent on resistance and c is the amount of minutes spent on cardio.
Alex's ratio: 24:30
Carisa's ratio: 15:20
Manuel's ratio: 14:15
Now you have to find the lowest common multiple (lcm) of the cardio minutes. Their lcm is 60. Now the ratios look like this:
Alex's ratio: 48:60
Carisa's ratio: 45:60
Manuel's ratio: 56:60
The ratio with the highest first number is considered larger. In this case its Manuel since he has the number 56.
Quadrilateral B is a scaled copy of Quadrilateral A.
It's shortest side is 5 units long
what's the scale factor for A to B?
please help.
The scale factor for A to B is 2 : 5.
Here, we are given that Quadrilateral B is a scaled copy of Quadrilateral A.
Quadrilateral A is as shown in the figure below.
The shortest side of quadrilateral B 5 units long.
From the figure, we can see that the shortest side of quadrilateral A is 2 units long.
Now, as the quadrilateral B is only a scaled copy of quadrilateral B, the ratio of their sides will be constant.
This means that-
Ratio of shortest side of A : Ratio of the shortest side of B = constant
and this constant is same for all corresponding sides. This constant is basically the scale factor.
Thus, scale factor = 2 : 5
Hence, the scale factor for A to B is 2 : 5

How do I solve this equation -3|x+5|+7=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−31x+51+7=4
(−31x)+(51+7)=4(Combine Like Terms)
−31x+58=4
−31x+58=4
Step 2: Subtract 58 from both sides.
−31x+58−58=4−58
−31x=−54
Step 3: Divide both sides by -31.
−31x / −31 = −54 / −31
x = 54 / 31
what is the area if one of the triangular side of the figure?
Compound Shape
The shape of the figure attached consists on four triangles and one square.
The base of each triangle is B=12 cm and the height is H=10 cm, thus the area is:
\(A_t=\frac{BH}{2}\)Calculating:
\(A_t=\frac{12\cdot10}{2}=60\)The area of each triangle is 60 square cm.
Now for the square of a side length of L=12.
The area of a square of side length a, is:
\(A_s=a^2\)Calculate the area of the square:
\(A_s=12^2=144\)The total surface area is:
A = 60*4 + 144
A= 240 + 144
A = 384 square cm

Find X,so that 7x+1,5x+7,and 2x-1 form an arithmetic sequence and write the first three terms.
The first three terms of the arithmetic sequence are -97, -63, and -29.
The value of x = -14.
How to Find the Terms in an Arithmetic Sequence?To find the value of x and the first three terms of the arithmetic sequence, we can equate the differences between consecutive terms:
The common difference (d) is the same between all consecutive terms.
So, we have:
(5x + 7) - (7x + 1) = (2x - 1) - (5x + 7)
Simplifying the equation:
5x + 7 - 7x - 1 = 2x - 1 - 5x - 7
-2x + 6 = -3x - 8
Now, let's solve for X:
-2x + 3x = -8 - 6
x = -14
Substituting the value of X back into the expressions, we can find the first three terms:
First term: 7x + 1 = 7(-14) + 1 = -97
Second term: 5x + 7 = 5(-14) + 7 = -63
Third term: 2x - 1 = 2(-14) - 1 = -29

the quadratic curve crosses the x axis at 3,0 and the y intercept is 9. express this in the equation y = ax2 + bx + c
Answer:
y = ax² - (3a + 3)x + 9
Step-by-step explanation:
The curve passes through 2 points: (3, 0) and (0, 9)
f(3) = 9a + 3b + c = 0
f(0) = 0 + 0 + c = 9
Therefore, c = 9, so plug this into the first equation:
9a + 3b + 9 = 0
We cannot determine a or b but for a given a we find that
b = - 3a - 3 ⇒ -b = 3a + 3
Therefore, we can express the quadratic curve as:
y = ax² - (3a + 3)x + 9

suppose: 1. all the points on a scatterplot lie perfectly on a straight line going uphill 2. the mean of x and the mean of y are both 2 3 the standard deviations of x and y are exactly the same. can you find the equation of the best fitting line with this information? (hint: think of the '5 number' way of finding the best-fitting line.) no, yes
Yes, we can find the equation of the best fitting line given the information provided.
Since all the points lie perfectly on a straight line going uphill, we know that there is a perfect linear relationship between x and y. Therefore, we can use the method of least squares to find the equation of the best fitting line.
The method of least squares involves finding the line that minimizes the sum of the squared distances between the observed data points and the predicted values on the line.
Given that the mean of x and the mean of y are both 2, we know that the line must pass through the point (2,2).
Since the standard deviations of x and y are exactly the same, we know that the slope of the line must be 1 (i.e., a unit increase in x corresponds to a unit increase in y).
Using the "5 number" approach, we can also find the equation of the line by calculating the correlation coefficient (r) between x and y. Since all the points lie perfectly on a straight line going uphill, the correlation coefficient will be either 1 or -1. In this case, since the line goes uphill, we know that the correlation coefficient must be 1.
Therefore, the equation of the best fitting line is y = x, or in slope-intercept form, y = 1x + 0.

An account with a $250 balance accrues 2% annually. If no deposits or withdrawals are made, which graph can be used to determine approximately how many years will it take for the balance to be $282?
Answer:
D. Graph 4 In an account with 250$ balance that accrues 2% annually, with no deposits or withdrawals, it takes 6 years and 6 months for the balance to be 282$
Step-by-step explanation:
if the balance accrues 2% annually, then that means every year the amount increases by 100% + 2% = 102%
102%= 102/100 = 1.02
if we multiply the balance in the account with 102% or by 1.02 at the beginning of each year we will get the amount accrued at the end of the year
First year: $250 x 1.02 = $260.1
Second year: 260.1 x 1.02 = $265.302
Third year: 265.302 x 1.02 = $270.60802
we can use these points to create a graph that will help us estimate at what year the amount will be 282$

A fraternity charge $2.00 admission for dudes and $1.00 admission for ladies. They made $45 and sold 35 tickets how many ladies attended the party
After solving the equations, we know that a total of 25 ladies attended the party.
What are equations?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
As in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including linear, quadratic, cubic, and others.
So, take dudes as x and ladies as y.
Now, form the required 2 equations as follows:
2x + y = 45 ...(1)
x + y = 35 ...(2)
Work on equation (2):
x + y = 35
x = 35 - y
Now, substitute x = 35 - y in equation (1):
2x + y = 45
2(35-y) + y = 45
70 - 2y + y = 45
-y = -25
y = 25
Since ladies were charged $1 for each ticket, then 25 ladies attended the party.
Therefore, after solving the equations, we know that a total of 25 ladies attended the party.

Maria has a jewelry box and wants to increase its size. She finds one with four times the length, width, and height. How many times bigger will the volume of the box be?
Answer:
64 times bigger
Step-by-step explanation:
I will use random values for this explanation to make it more understandable.
Lets say the length of the box is 1 inch, width is 1 inch, and height is 1 inch.
The volume would be l*w*h = 1*1*1 = 1 cubic inch
If the dimensions were 4 times bigger, the length, width and height would all be 4 inches.
4*4*4 = 64 cubic inches, which is 64 times bigger than the smaller box with a volume of 1 cubic inch.
