1. The amount donated by the people with same ratio is $40.
2. The amount greater is $40.
How to calculate the value?From the information, there's a total of $160 in donations from three people and the three donations are in the ratio 5 : 5 : 10.
It should be noted that the amount donated by the people with same ratio will be:
= 5/(5 + 5 + 10) × $160
= 5/20 × $160
= $40
The amount donated by the person with largest ratio will be;
= 10/20 × $160
= $80
Therefore, the difference will be:
= $80 - $40
= $40

The director of a marching band asks the band members to line up in rows of six, but there are three band members in the last row. Then she tries to line them up in rows of seven, but there are four band members in the last row. Finally, she tries to line them up in rows of eight, but there are five band members in the last row.
The band has fewer than 200 members.
How many members are there?
Using divisibility rules, it is found that there are 165 members in the band.
How to determine how many members are there in the band?The number of students in the last row gives the remainder of the division of the total number of members by the number of members in each row.
Hence:
The number of members in the band divided by 6 has a remainder of 3The number of members in the band divided by 7 has a remainder of 4.The number of members in the band divided by 8 has a remainder of 5.It is also stated that the band has fewer than 200 members.
From the third bullet point, the possible values, that is, values that when divided by 8 have a remainder of 5, are given as follows:
{5, 13, 21, 29, 37, 45, 53, 61, 69, 77, 85, 93, 101, 109, 117, 125, 133, 141, 149, 157, 165, 173, 181, 189, 197}.
The number is 165, because:
165/6 = 27 with a remainder of 3.165/7 = 23 with a remainder of 4.More can be learned about divisibility rules at https://brainly.com/question/9462805

solve the following equation a+2_3 =3_4
The solution for the linear equation is:
a = 1/4.
How to solve the equation?I believe we have the linear equation:
(a + 2)/3 = 3/4
To solve this, we need to isolate the variable a in one of the sides of the linear equation, to do so, we can start by multiplying both sides by 3.
3*(a + 2)/3 = 3*(3/4)
a + 2= 9/4
Now we can subtract 2 in both sideS:
a + 2 - 2 = 9/4 - 2
a = 9/4 - 8/4 = 1/4

1. 200 - 7/21
2. 50 - 4/7
3. 24 1/4 - 20 3/5
4. 10 5/8 - 6 4/9
5. 6 1/2 - 5 3/4
Step-by-step explanation:
1.
200 - 7/21 = (200×21 - 7)/21 = (4200 - 7)/21 =
= 4193/21 = 599/3 = (199×3 + 2)/3 =
= 199 2/3
we could have seen that 7/21 = 1/3.
so, then this problem was
200 - 1/3 = (200×3 - 1)/3 = 599/3 = 199 2/3
(see above)
2.
50 - 4/7 = (50×7 - 4)/7 = (350 - 4)/7 =
= 346/7 = (49×7 + 3)/7 = 49 3/7
3.
24 1/4 - 20 3/5 = (24×4 + 1)/4 - (20×5 + 3)/5 =
= 97/4 - 103/5
to calculate this we need to bring both fractions to the save denominator. the LCM (lowest common multiple) of 4 and 5 is 20.
so,
97/4 - 103/5 = (97×5)/(4×5) - (103×4)/(5×4) =
= 485/20 - 412/20 = 73/20 =
= (3×20 + 13)/20 = 3 13/20
4.
10 5/8 - 6 4/9 = (10×8 + 5)/8 - (6×9 + 4)/9 =
= 85/8 - 58/9
the LCM of 8 and 9 is 72.
85/8 - 58/9 = (85×9)/(8×9) - (58×8)/(9×8) =
= 765/72 - 464/72 = 301/72 =
= (4×72 + 13)/72 = 4 13/72
5.
6 1/2 - 5 3/4 = (6×2 + 1)/2 - (5×4 + 3)/4 =
= 13/2 - 23/4
the LCM of 2 and 4 is 4.
13/2 - 23/4 = (13×2)/(2×2) - 23/4 =
= 26/4 - 23/4 = 3/4
Find the difference in the latitudes of Athens, Greece, Latitude 38° N, and Sydney, Australia, latitude 34° S.
The difference in the latitudes of Athens, Greece, Latitude 38° N, and Sydney, Australia, latitude 34° S is 72° .
We have two different coordinates, 38° N and 34° S
We can find the differnce in two different coordinates by following a few steps.
We have to consider South as negative North. So, we can write 34° S as -34° N.
Hence, we can determine the difference in between two coordinates.
Difference in coordinates ≡ 38° N - 34° S = 38° N - ( - 34° N ) = 38° N + 34° N = 72° N
So, we can conclude that, the difference is 72°.

Determinants are only determined using square matrices. If a matrix's determinant is zero, it is referred to as a singular determinant; if it is one, it is referred to as a unimodular matrix. For the system of equations to have a single solution, the determinant of the matrix must be nonsingular, or its value must be nonzero.In this post, we will discuss the definition of determinants and matrices, as well as their many types, characteristics, and instances.Calculation:

Four ways to find the slope and y–intercept of straight line equation are;
Making use of the graph to find the slopeObtaining the coordinates of the x–intercept, Looking for the y–intercept when the slope and a point is knownSolving for the slope when two points are givenWhat is a straight line equation?A straight line equation is of the form, y = m•x + c
Where;
m = The slope of the graph of the equation
c = The point the graph intersects the x–axis.
The process by which the slope–intercept form of a straight line equation can be found from the above ways are as follows;
1. Making use of the graph of the equation
When the graph is given, the y–intercept is found from the point the graph crosses the y–axis
Note the y–intercept
Find two points on the graph where coordinates can be obtained
Find the ratio of the rise to the run to get the slope of the graph
[tex] \displaystyle{ Slope, \: m = \frac{ rise}{run} } = \frac{ \triangle y }{\triangle x} [/tex]
With the slope and y–intercept, the equation of the line can be written as; y = m•x + c
2. Obtaining the coordinates of the x–intercept
Given the slope and the y–intercept, the x–intercept can be found by plugging in the values of the slope, m, and the y–intercept, c, in the equation, y = m•x + c, to get the equation of the line
From the equation, the x–intercept can be found by plugging y = 0, to get;
0 = m•x + c
The x–intercept becomes, [tex] \displaystyle \frac{-c}{m} [/tex]
The graph can then be plotted by drawing a line through the x and y–intercept
3. Finding the y–intercept given the slope and the x–intercept
When the slope and the x–intercept and the slope is known, whole number part of the numerator can be added to the x–value of the x–intercept to obtain the x–coordinates of a second point on the graph
The process is repeated to find the y–coordinate of the second point
The slope is calculated using the two points and the equation for the slope given in the first method
4. When two points are known, the slope is calculated using the equation in method 1
The two are joined with a straight line and the y–intercept is obtained from the point the graph intersects the y–axis

Answer: Question E: The answer is that A(9) is greater.
Step-by-step explanation:
For questions A and C, you can see that the table is exponentially growing. So the equation will use multiplication. You can also see the value of the equation is growing by x2.
So you could say the table starts at a base of 1/2, then grows exponentially at a rate of 2. (Basically saying the value grows x2 per term). The equation will result in y= 1/2(2)^x
For questions B and D, you can see that the graph is growing linearly. So the equation will use multiplication.
By drawing a line between the lines you can easily see the growth of the triangle. You can then tell the 0th term to 1st term goes right 1 and up 10.
Next, you look at the 1st term to the 2nd term. You can tell that it goes right 1 and up 10. So, the rate is 10 per term. (10x) and it starts at 2 (+2). The equation will result in y=10x+2
Question E, solve each equation by substituting the x by 9.
A(9)
y= 1/2(2)^x
y= 1/2(2)^9
y= 1/2(512)
y=256
B(9)
y=10x+2
y= 10(9) +2
y= 90+2
y=92
The answer is that A(9) is greater.

If the distance from 0 to x on a number line is greater than 0, then -5 + x is positive?
True or false
True.
Given the statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.
For the given question,
The distance from 0 to x on a number line is greater than 5
We write the above statement in mathematical expression form as,
⇒ |x - 0| > 5
⇒ |x| > 5
⇒ x > 5
We need to determine the value of an expression -5 + x
From (1),
⇒ x > 5
Subtract -5 from both sides,
⇒ -5 + x = -5 + 5
⇒ -5 + x > 0
From the above expression, we observe that the value of the expression is always greater than 1.
This means the value of an expression -5 + x is positive.
Therefore, the given statement 'If the distance from 0 to x on a number line is greater than 5, then -5+x is positive' is True.
In mathematics, a number line can be described as a figure that symbolizes numbers on a consecutive line. The digits on a number line are positioned successively with equal spacing along its length. It can be infinitely expanded in any direction and is often depicted horizontally.
Absolute value is the distance between a digit and zero on a number line. Since the space is forever positive, the absolute value will always be positive.
