A girl's club held a fundraiser last year and raised $600 for the local soup kitchen. This year they raised $960. What is the percent change in the total amount raised by the girl's club? The percent change is 0.38%. The percent change is 0.6%. The percent change is 38%. The percent change is 60%.
Answer:
The percent change is 60%.
Step-by-step explanation:
given that the old amount is
$600
also the new amount is $960
the change is 960-600= $360
therefore the expression for percent change is given as
%change= new-old/old
%change= final-initial/initial
%change= 960-360/360
%change= 360/600
%change= 0.6
0.6*100
=60%
The percent change is 60%.

Find three consecutive even integers such that the sum of twice the smallest number and three times the largest is 42.
Answer:
The three consecutive even integers are 6, 8, 10
Step-by-step explanation:
The difference between each two consecutive even numbers is 2Assume that the first number is x, then the other two numbers are x + 2 and x + 4∵ The three consecutive even numbers are x, x + 2, x + 4
∵ The smallest number is x
∴ Twice the smallest number = 2x ⇒ (1)
∵ The largest number is x + 4
∴ Three times the largest number = 3(x + 4) = 3(x) + 3(4)
∴ Three times the largest number = 3x + 12 ⇒ (2)
∵ The sum of twice the smallest number and three times the largest is 42
→ Add (1), (2) and equate the sum by 42
∴ 2x + 3x + 12 = 42
→ Add the like terms
∴ 5x + 12 = 42
→ Subtract 12 from both sides
∴ 5x + 12 - 12 = 42 - 12
∴ 5x = 30
→ Divide both sides by 5
∵ [tex]\frac{5x}{5}=\frac{30}{5}[/tex]
∴ x = 6
∴ The smallest integer is 6
∴ The middle integer is 6 + 2 = 8
∴ The largest integer is 6 + 4 = 10
∴ The three consecutive even integers are 6, 8, 10

When the expression x^2 + bx - 24 is factored completely, the difference of the factors is 11. Find both factors if it is known that b is negative.
write the steps on the paper pleaseeee
i need it asap
Answer:
The two factors are (x + 3) and (x - 8)
Step-by-step explanation:
The given function is x² + b·x - 24
The difference between the factors = 11
The sign of coefficient b = Negative
Therefore, we have;
The factors as (x - c) and (x + d)
-b = d - c...(1)
d × (-c) = -24...(2)
(x + d) - (x - c) = 11
Which gives;
x + d - x + c = 11
∴ d + c = 11...(3)
From equation (3), we have;
d = -24(-c) = 24/c
d = 24/c
Substituting the value of d in equation (3) gives;
d + c = 24/c + c = 11
24/c + c = 11
∴ c² + 24 = 11·c
c² + 24 - 11·c = 0
c² - 11·c + 24 = 0
(c - 8)·(c - 3) = 0
c = 8 or 3
From d + c = 11, we have, d = 3 or 8
Given that -b = d - c, therefore c > d and c = 8, d = 3
Therefore, the two factors are (x - 8) and (x + 3).

Answer:
x^2+8x +16 >> (x+4)^2
x^3-64 >> (x-4)(x^2+4x+16)
x^2-16 >> (x-4)(x+4)

Polynomial is an expression that consists of indeterminates(variable) and coefficients.
What are polynomials?
Polynomial is an expression that consists of indeterminates(variable) and coefficients, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
To know which polynomial to match, solve the factors.
A.) (x-4)(x²+4x+16)
[tex](x-4)(x^2+4x+16)\\\\=x(x^2+4x+16)-4(x^2+4x+16)\\\\= x^3 + 4x^2 + 16x - 4x^2-16x-64\\\\=x^3 -64[/tex]
Hence, (x-4)(x²+4x+16) will match x³-64.
B.) (x+4)²
[tex](x+4)^2\\\\= x^2+8x+16\\[/tex]
Hence, (x+4)² will match x²+8x+16.
C.) (x-4)(x+4)
[tex](x-4)(x+4)\\\\ = x^2-16[/tex]
Hence, (x-4)(x+4) will match x²-16.

8 pints = 3.785 litres
1 gallon = 3.785 litree
18.640350877 gallons = y
Cross Multiply
18.640350877 litres × 3.785
= 70.5537280694 gallons
c) 1 litres = £1.09

Answer:
y = x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (8, 4)
m = [tex]\frac{4+4}{8-0}[/tex] = [tex]\frac{8}{8}[/tex] = 1
The line crosses the y- axis at (0, - 4 ) ⇒ c = - 4
y = x - 4 ← equation of line
