There are 100 seniors and 80 juniors in the Homecoming Parade. The students split up into groups of equal size, to fit on the parade floats. They want the most students possible on each float, with just juniors or just seniors on each float. How many students should be on each float?
Answers
Answer:
20 students should be on each float
Step-by-step explanation:
Number of seniors = 100
Number of juniors = 80
To find number of students that should be on each float, find highest common factor (H.C.F) of 100 and 80
Write prime factorisation of 100 and 80.
100 = [tex]2^2[/tex] × [tex]5^2[/tex]
80 = [tex]2^4[/tex] × 5
So,
H.C.F(100, 80) = [tex]2^2[/tex] × 5 = 4 × 5 = 20
Therefore,
20 students should be on each float

It is 14 because the function of g equals 5 and the function of f equals 9
Answer:
c) 14
Step-by-step explanation:
f(x) = x²
f(-3) = (-3)² = -3 * - 3 = 9
g(x) = 2x - 3
g(4) = 2*4 - 3 = 8 - 3 = 5
g(4) + f(-3) = 5 + 9

If the fraction 374/×-10 is equivalent to -22, find the value of x.
Answers
Answer:
uhm -7?
Step-by-step explanation:
374 ÷ (x - 10) = -22
374 = -22(x - 10)
374 = -22x + 220
374 - 220 = -22x
154 = -22x
154 ÷ -22 = x
-7 = x

Write an equation that is parallel to 3x−2y=14 and passes through the point (-6, -11) in slope-intercept form.
Answers
3*-6-2*-11=14
-18+22=14
22=14+18

Answer: First, remember that parallel lines have the same slope. So we first need to find the slope of the line we are given, 3x+2y=27. The quickest way to find the slope of this line is to put it into slope-intercept form (y=mx+b)
subract 3x from both sides:
2y=-3x+27
divide each term by 2:
y=-3/2x +27/2
Now we can see that the slope is -3/2.
From here, we use the slope we found and the ordered pair given (7,-4) and find the equation of the new line. We will have to use point-slope form (y-y1)=m(x-X1) to find the new line because the ordered pair given is not the y-intercept.
(y-(-4))=-3/2(x-7)
distribute -3/2:
(y-(-4))= -3/2x + 21/2
simplify double negative on left side of equals sign:
y+4=-3/2x + 21/2
Subtract 4 from both sides:
y= -3/2x + 13/2
This is your answer in slope intercept form. Because the directions specifically ask for standard form, we have one more step. Standard form (ax+by=c) needs the terms with x and y to be on the same side of the equals sign. So, we simply have to move the term with x (-3/2x) to the other side by adding.
Finished product:
3/2x+y= 13/2

A rectangular pool has an area of 5x2 + 23x + 12 and the length of one side is 5x + 3. What is the
length of the other side?
Answers
Answer:
x + 4
Step-by-step explanation:
Area of rectangle= length × breadth
In this question, one length is 5x + 3 and the area is 5x^2 + 23x + 12
This means that;
5x2 + 23x + 12 = 5x + 3 (b)
Hence, to get the other length (b) = 5x2 + 23x + 12/ 5x + 3
To get the other length, we can factorize the algebraic expression;
5x2 + 23x + 12
Product: 60x^2 (20x × 3x)
Sum: +23x (20x + 3x)
Hence;
= 5x^2 + 20x + 3x + 12
Next, we find factors;
5x (x+4) + 3 (x+4)
Therefore, the factors are (5x + 3) and (x +4)
This means that the other length is (x +4)

Barbara bought 5 amusement park tickets at a cost of $30. If she bought 7 tickets, how much would it cost?
It would cost $
.
Answers
Answer:
$42
Step-by-step explanation:
5 divided by $30 so each ticket would be $6 then just multiply $6 and 7
Answer:
It would cost $42 because 30 divided by 5 equals 6, so that's saying for each 1 ticket it costs $6. So with the new equation, 7 x $6, we get $42. Which will end up being the cost for 7 tickets.

Answers
Answer:
7.7% decrease in the value of the moped
Step-by-step explanation:
Bree bought a 1994 moped for $3,500
A year later the value of the moped dropped to $2,730
Therefore the percent of decrease of the value of the moped can be calculated as follows
= 3,500-2,730/100
= 770/100
= 7.7 % decrease
Hence there was a 7.7% decrease in the value of the moped
