One supermarket sold 72 cases of Zing soap, but only one-third as many cases of Essence soap. If each case holds 156 bars of soap, how many bars were sold in all
There will be 1334 bars sold in all if each case holds 156 bars of soap.
From the question, we are told that one supermarket sold 72 cases of Zing soap, if there is only one-third as many cases of Essence soap, then;
Amount of cases of Essence soap = one-third of 72
Amount of cases of Essence soap = [tex]\frac{1}{3} \times 72[/tex]
Amount of cases of Essence soap = 24cases
If each case holds 156 bars of soap, then we can write:
1 case = 56 bars of soap
To get the total bars that were sold. we can write:
24cases = x
DIvide both expressions:
[tex]\frac{1}{24} = \frac{56}{x} \\cross \ multiply\\1 \times x=24 \times 56\\x=1334 bars[/tex]
This shows that 1334 bars were sold in all

Look at the graph.
The graph shows a line through the points left parenthesis negative 1 comma negative 2 right parentheses and left parenthesis 2 commas 1 right parenthesis.
The slope of the line is _______.
A. positive
B. negative
C. zero
D. undefined
Answer:
the slope is POSITIVE (answer A)
Step-by-step explanation:
The line goes through: (-1, -2) and ( 2, 1)
Then the slope can be calculated as:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (1 - -2) / (2 - -1) = (1 + 2) / (2 + 1) = 3 / 3 = 1
Therefore, the slope is POSITIVE (answer A)
Factor the expression using the GCF. 58+28=
Answer:
2(29+14)
Step-by-step explanation:
Given function:
To find the GCF of 58+28..Find the GCF of 58+28:
[tex]58=29[/tex]·[tex]2[/tex] [tex]28=14[/tex]·[tex]2[/tex]Rewrite:
[tex]2(29+14)[/tex]Therefore, using GCF, the new expression would be 2(29+14)..
The expression 58 + 28 can be factorized as 2 (29 + 14).
What is GCF?GCF which is the abbreviated form for Greatest Common Factor of two numbers, as the name implies, is the greatest common factor of both the numbers.
GCF of two numbers can be found using prime factorization.
Given the expression 58 + 28.
To find the GCF of two numbers, list the prime factors of these two numbers.
58 = 2 × 29
28 = 2 × 14 = 2 × 2 × 7
The only common factor is 2.
So the greatest common factor is 2.
58 + 28 = (2 × 29) + (2 × 14)
Taking the common factor of 2 outside the brackets,
58 + 28 = 2 (29 + 14)
Hence the expression 58 + 28 can be factorized as 2 (29 + 14) using the greatest common factor.

Members of a soccer team raised $1719 to go to a tournament. They rented a bus for
$1051.50 and budgeted $44.50 per player for meals. Write and solve an equation
which can be used to determine z, the number of players the team can bring to the
tournament.
Answer:
44.5x + 1051.5 = 1719
x = 15
Step-by-step explanation:
DeltaMath
The number of players the team can bring to the tournament is 15.
Given:
The total amount of money raised by the soccer team = $1719
Amount to rent the bus = $1051.50
Amount budgeted for each player's meal = $44.50
To find:
Equation and the number of players the team can bring to the tournament
Solution:
The number of players the team can bring to the tournament = z
Amount budgeted for each player's meal = $44.50
Total amount needed for z number of players' meals = $44.50z
Amount to rent the bus = $1051.50
The total amount of money raised by the soccer team = $1719
The equation for numbers of players will be written as:
[tex]\$44.50z+ \$1051.50= \$1719\\\$44.50z= \$1719- \$1051.50\\\$44.50z=\$667.50\\z=\frac{\$667.50}{\$44.50}=15[/tex]
The number of players the team can bring to the tournament is 15.

Let f(x)=18/1+3^e-0.1x What is the point of maximum growth rate for the logistic function f(x)? Show all work. Round your answer to the nearest hundredth
Answer:
(0, 4.5)
Step-by-step explanation:
*The equation can be put into Desmos, to find the point, but the work to prove it is here*
f(x)=c/1+Ae^-Bx
Y=C
C=18 A=3 -B=-0.1
*Replace x with 0 in the equation, so you know 0 is the x value, and it leads you to the y value*
f(0)=18/1+3e^-o.1(0)
= 18/1+3e^0
=18/1+3(1)
=18/1+3
=18/4
=4.5
x=0 y=4.5
Maximum growth rate = (x,y) --> (0, 4.5)

The graph of y = 4x2 - 4x – 1 is shown.
Use the graph to find estimates for
the solutions of
i) 4x2 - 4x – 1 = 0
ii) 4x2 - 4x - 1 = 2
Answer:
i) The approximate solutions are: [tex]x_{1} \approx -0.207[/tex], [tex]x_{2} \approx 1.207[/tex].
ii) The approximate solutions are: [tex]x_{1}\approx -0.5[/tex], [tex]x_{2} \approx 1.5[/tex].
Step-by-step explanation:
i) The best approach to estimate graphically the solution of [tex]4\cdot x^{2} - 4\cdot x - 1 = 0[/tex] is graphing the following system of equations:
[tex]y = 4\cdot x^{2}-4\cdot x - 1[/tex] (1)
[tex]y = 0[/tex] (2)

What is the surface area
Answer:
red) area = 59.2 km²
Step-by-step explanation:

area of 4 sides = 4 (1/2)(4)(5.4) = 43.2
16 + 432 = 59.2 km²
Answer:
Step-by-step explanation:
lateral area = 2(base)(slant height) = 2·4·2 = 16 km²
base area = base² = 4² = 16 km²
