Answer:
24
Step-by-step explanation:
Take the total amount of margarine used and divide it by the used per batch. 375/125 equals 3. This means James made 3 batches so we multiple the ammount of flapjacks per batch by the number of batches. 3*8 equals 24.
Answer:
24 flapjacks
Step-by-step explanation:
One recipe of flapjacks takes 125g of margarine and James is using 375. To find out how many recipes James is making divide the amount of margarine he is using (375g) by the amount of margarine needed in 1 recipe (125g).
375÷125=3
One recipe makes 8 flapjacks and since James is making 3 recipes you multiply 3 by 8 to get the number of flapjacks that James is making.
8*3=24

Answer:
d=rt is basically y=mx+b but with different variables. B is where the line intercepts the y axis and since this line intercepts at 0, 0 b can automatically be deleted from the equation. therefore d=rt is equivilent to y=mx
The slope is 6. I know this by looking at the first point of the line (0, 0) and finding the next point on the line (1, 6). To get from 0, 0 to 1,6 you need to go up 6 and over 1. Since rise/run is the slope of a line 6/1 or 6 is the slope.
At 1, 6 we see that in 1 hour, joseph went 6 miles. Therefore the constant rate is 6 miles per hour (6 mp/h.)
The slope, already found, is 6 and therefore if d=rt is equivilent to y=mx we can write our equation as d=6t
6 mp/h
d=6t

4v = 20
Help please
Answer:
v=5
Step-by-step explanation:
you are trying to make 4v into v right ?
so simply divide it by 4 - the same if it was 4a or 7a or 9k, always start by dividing by the number
then you need to balance the two sides - so whatever number you divide the letter by (which is the 4 in this case) , you do the same with the other side , so whatever number is after the equal sign , divide it by 4
PART ONE ↓ 4v = 20
DIVIDE BY 4 → v = 20
PART TWO v = 20 ↓
v = 5 ← DIVIDE BY 4

Jack is getting balloons for his uncle's birthday party. He wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Jack wants to get 55 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answer:
110 yards of string
Step-by-step explanation:
Converting the feet of the string of 1 balloon to yard
1 foot = 1/3 yard
6 feet = x
x = 6 × 1/3 yard
x = 2 yard
Hence 1 balloon uses 2 yard of string
Since:
1 balloon = 2 yard of string
55 ballons = x
x = 55 × 2 yard of string
x = 110 yards of string
Hence, for 55 balloons he would need 110 yards of string.
2x+3y= -18 on the graph
Answer:
graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.
Step-by-step explanation:
First simplify. 2x+3y= -18., -----------> 3y= -2x -18., ---------> y= -2/3x -6
To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.

(a) Find an expression for the perimeter of the triangle in terms of r, giving
your answer in its simplest form.
(b) Work out the value of r, if the perimeter is 49 cm.
Answer:
a). Perimeter = (5r + 9) cm
b). r = 8
Step-by-step explanation:
Property of isosceles triangle:
- Two sides of an isosceles triangle are equal.
- Opposite sides of the equal angles are equal in measure.
From the figure attached,
PQ = QR = (2r + 3)
a). Since perimeter of a polygon = sum of all sides of the polygon
= PQ + QR + PR
= (2r + 3) + (2r + 3) + (r + 3)
= 5r + 9
Perimeter of the given triangle = (5r + 9) cm
b). Perimeter of the given triangle = 49 cm
(5r + 9) = 49
5r = 40
r = 8

The tree casts a shadow 48ft long. At the same time of day an alien who is 7ft tall
casts a shadow 12ft long. What is the height of the tree? Explain or show all work.
Answer:
28 ft
Step-by-step explanation:
Since the shadows were cast at the same time of the day, both triangular images formed would be similar to each other.
Therefore, the ratio of their corresponding sides would be equal.
That is, the height of the tree / the height of the alien = the shadow of the tree / the shadow of the alien
Height of the tree = x ft
Height of the alien = 7 ft
Shadow of the tree = 48 ft
Shadow of the alien = 12 ft
Plug in the values into the proportional equation stated earlier.
Thus, the ratio of their corresponding sides would be:
[tex] \frac{x}{7} = \frac{48}{12} [/tex]
Cross multiply
[tex] x*12 = 48*7 [/tex]
[tex] 12x = 336 [/tex]
Divide both sides by 12
[tex] x = \frac{336}{12} [/tex]
[tex] x = 28 [/tex]
The height of the tree = 28 ft

David invested $340 in an account paying an interest rate of 2\tfrac{1}{8}2 8 1 % compounded continuously. Natalie invested $340 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded quarterly. After 17 years, how much more money would Natalie have in her account than David, to the nearest dollar?
Answer:
$53.83
Step-by-step explanation:
For David
David invested $340 in an account paying an interest rate of 2\tfrac{1}{8}2 8 1 % compounded continuously.
r = 2 1/8% = 17/8% = 2.125% = 0.02125
t = 17 years
P = $340
For Compounded continuously, the formula =
A = Pe^rt
A = Amount Invested after time t
P = Principal
r = interest rate
t = time
A = $340 × e^0.02125 × 17
A = $ 487.94
For Natalie
Natalie invested $340 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded quarterly.
r = 2 3/4 % = 11/4% = 2.75% = 0.0275
t = 17 years
P = $340
n = compounded quarterly = 4 times
Hence,
Compound Interest formula =
A = P(1 + r/n)^nt
A = Amount Invested after time t
P = Principal
r = interest rate
n = compounding frequency
t = time
A = $340 (1 + 0.0275/4) ^17 × 4
A = $ 541.77
After 17 years, how much more money would Natalie have in her account than David, to the nearest dollar?
This is calculated as
$541.77 - $ 487.94
= $53.83
Hence, Natalie would have in her account, $53.83 than David
Solve five ninths minus two sixths equals blank.
twelve fifty fourths
twenty fifty fourths
six thirds
three over one
The result of five ninths minus two sixths is two - ninths.
Let us first write the words in figures so that we can perform the required calculation;
five ninths = 5/9
two sixths = 2/6
This means that we are simply asked to subtract 5/9 from 2/6
Hence;
5/9 - 2/6, we have to take LCM. The LCM of 5/9 and 2/6 is 18. The term LCM actually means lowest common multiple of 9 and 6.
So;
[tex]\frac{10 - 6}{18} = \frac{4}{18} = \frac{2}{9}[/tex]

Answer:
[tex]a_n=-4n+10[/tex]
Step-by-step explanation:
Let us consider the given terms one by one:
First term, [tex]a[/tex] = 6
Second term, [tex]a_2=2[/tex]
Difference between First and Second term = 2 - 6 = -4
Third term, [tex]a_3[/tex] = -2
Difference between Second and Third term = -2 - 2 = -4
Fourth term, [tex]a_4[/tex] = -6
Difference between Second and Third term = -6 -(-2) = -4
Therefore, the common difference is:
[tex]d[/tex] = -4
Let the use the formula for [tex]n^{th}[/tex] term of an arithmetic sequence:
[tex]a_n=a+(n-1)d[/tex]
Putting the values of [tex]a[/tex] and [tex]d[/tex]:
[tex]a_n=6+(n-1)(-4)\\\Rightarrow a_n=6-4n+4\\\Rightarrow a_n=-4n+10[/tex]
Therefore, the [tex]n^{th}[/tex] term is:
[tex]a_n=-4n+10[/tex]
The function that generates the sequence 6, 2, -2, -6, ... is: f(n) = 6 - 4(n - 1)
To generate the arithmetic sequence 6, 2, -2, -6, ... , use the general formula for an arithmetic sequence:
an = a1 + (n - 1)d
A) f(n) = 6 - 4n
If we substitute n = 1, we get f(1) = 6 - 4(1) = 2, which matches the second term of the sequence.
However, it doesn't generate the rest of the sequence, so it is not correct.
B) f(n) = 6 - 4(n - 1)
If we substitute n = 1, we get f(1) = 6 - 4(0) = 6, which matches the first term of the sequence.
By substituting other values of n, we can verify that this function generates the entire sequence. It is correct.
C) f(n) = 6 + 4(n - 1)
If we substitute n = 1, we get f(1) = 6 + 4(0) = 6, which matches the first term of the sequence.
However, it doesn't generate the rest of the sequence, so it is not correct.
D) f(n) = 6 - 2n
If we substitute n = 1, we get f(1) = 6 - 2(1) = 4, which does not match the first term of the sequence. It is not correct.
Based on the analysis above, the function that generates the sequence 6, 2, -2, -6, ... is: f(n) = 6 - 4(n - 1)
