A bakery sells white loaves and brown loaves.
One week, the ratio of the number of white loaves sold to the number of brown loaves
sold was 4:5
The bakery sold a total of 1584 loaves that week.
Work out how many brown loaves they sold.
Answer:
880 brown loaves
Step-by-step explanation:
Create a ratio of brown loaves to total loaves by adding the the current ratio, 4:5 together.
4 + 5 = 9.
Now create the new ration of brown loaves to total loaves.
5:9
Next make a proportion using brown (numerator) to total (denominator).
Then cross multiply and divide.
[tex]\frac{5}{9} = \frac{b}{1584}[/tex]
[tex]9b = 7920\\\frac{9b}{9} =\frac{7920}{9} \\b=880[/tex]

Find the circumference of this circle. Use 3.14 to approximate T.
C = 27r
14 ft
C = [ ? ] ft
Answer:
43.98229 ft
Step-by-step explanation:
The diameter is 14ft, meaning the radius, which is half of it, is 7ft. Plug 7 into the r. C= 2pi(7) which 14pi. Now you multiply 14 by 3.14, which is the value of pi, and round it to whatever you need to give you your value.
The value of circumference of this circle is,
⇒ circumference = 14π ft
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Diameter = 14 ft
Hence, We get;
Radius = 7 ft
Thus, The value of circumference of this circle is,
⇒ circumference = 2πr
⇒ circumference = 2 × π × 7
⇒ circumference = 14π ft
Thus, The value of circumference of this circle is,
⇒ circumference = 14π ft

Rectangular Prism’s Volume:
[tex]\displaystyle \large{V=\sf{width*length*height}}[/tex]
Given:
width = 2.1 ft
length = 4 ft
height = j
volume = 75.6 cubic feet
Therefore, apply given information in the formula:
[tex]\displaystyle \large{75.6=2.1*4*j}\\\displaystyle \large{75.6=8.4j}[/tex]
Divide both sides by 8.4 to solve for j.
[tex]\displaystyle \large{\dfrac{75.6}{8.4}=\dfrac{8.4j}{8.4}}\\\displaystyle \large{\dfrac{75.6}{8.4}=j}\\\therefore \displaystyle \large{j=9}[/tex]
Henceforth, the value of j is 9 feet.
The graph of the function f(x)=x^2-6x shifted 2 units to the left on the graph of g(x). Select the two functions that represent the shift of f(x) onto g(x)
Answer:
Step-by-step explanation:
g( x ) = f ( x + 2 )
g(x) = ( x + 2 )² - 6 ( x + 2 )
g(x) = x² + 4x + 4 - 6x - 12
g(x) = x² - 2x - 8

Let’s say that in these congruent triangles, the length of side AB in the first triangle is 6 feet. What is the length of side DE in the second triangle?
Answer:
6 feet
Step-by-step explanation:
Corresponding vertices of the congruent triangles are listed in the same order in the congruence statement. Given that ΔABC ≅ ΔDEF, that means vertices A and B correspond to vertices D and E.
Segment DE will have the same length as segment AB, 6 feet.

Step-by-step explanation:
Sasha is making custom designs using these small trapezoidal prisms. She wants to cover each of the 8 prisms in her current design in striped cloth on all sides. She has 3500 square centimeters of striped cloth.
Does Sasha have enough cloth to cover all 8 prisms in her current design?
Choose from the drop-down menus to correctly complete the statement.
The combined surface area of the prisms is cm², therefore Sasha have enough cloth for her current design.
Combined surface area for the 8 prisms is: 3,040 square centimeters.
3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth for the design.
What is the Surface Area of a Trapezoidal Prism?Surface area = (b1 + b2)h + PH
Given the following dimensions:
b1 = 5 cmb2 = 15 cmHeight of trapezium (h) = 7 cmPerimeter of trapezium (P) = 15 + 10 + 10 + 5 = 40 cmHeight of prism (H) = 6 cmPlug in the values into SA = (b1 + b2)h + PH:
Surface area = (5 + 15)7 + (40)(6)
Surface area = 380 sq. cm.
Combined surface area for the 8 prisms = 380 × 8 = 3,040 square centimeters.
3,500 cm² > 3,040 cm², therefore, Sasha has enough cloth.

Answer:
The combined surface area of the prisms is 3040 cm², therefore Sasha does have enough cloth for her current design.
Step-by-step explanation:
7 + 6 = 13 (Length + Height)
13 x 5 = 65 side a (h + l)
15 x 13 = 195 side b (h+l)
10 x 6 = 60 side c x length
10 x 6 = 60 side d x length
All of the above added together is 380, one trapezoidal prism.
380 x 8 = 3040

C(-25, -0.2)
The formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.
What is inversely proportional relationship?Let m and n are two variables.
Then m and n are said to be inversely proportional to each other if
[tex]m = \dfrac{c}{n} \\\\ \text{or} \\\\ n = \dfrac{c}{m}[/tex]
(both are equal)
where c is a constant number called constant of proportionality.
This inversely proportional relationship is denoted by
[tex]m \propto \dfrac{1}{n} \\\\ \text{or} \\\\n \propto \dfrac{1}{m}[/tex]
As visible, increasing one variable will decrease the other variable if both are inversely proportional.
The formula for the inverse function is given as,
[tex]y=\dfrac{c}{x}[/tex]
Here, c is constant.
The graph goes through the point: C(-25, -0.2). For the inverse function.
[tex]-25\propto\dfrac{1}{-0.2}\\-25=\dfrac{c}{-0.2}\\c=-25\times-0.2\\c=5[/tex]
Put the value in the above function,
[tex]y=\dfrac{5}{x}[/tex]
This is the required function.
Hence, the formula for an inverse proportion, knowing that its graph goes through the point: C(-25, -0.2) is y=5/x.

What value of x is in the solution set of 4x - 12 S 16 + 8x?
You gave little context, so here is a few solutions.
POSSIBLE #1:
assuming s is a variable
---> Simplify [tex]12S[/tex] × [tex]16[/tex] to [tex]192S[/tex]
[tex]4x-192S+8x[/tex]
---> Collect like terms.
[tex](4x+8x)-192S[/tex]
---> Simplify.
[tex]12x-192S[/tex]
POSSIBLE #2: (assuming s is not relevant)
Simplifying
4x + -12 = 16 + 8x
Reorder the terms:
-12 + 4x = 16 + 8x
Solving
-12 + 4x = 16 + 8x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8x' to each side of the equation.
-12 + 4x + -8x = 16 + 8x + -8x
Combine like terms: 4x + -8x = -4x
-12 + -4x = 16 + 8x + -8x
Combine like terms: 8x + -8x = 0
-12 + -4x = 16 + 0
-12 + -4x = 16
Add '12' to each side of the equation.
-12 + 12 + -4x = 16 + 12
Combine like terms: -12 + 12 = 0
0 + -4x = 16 + 12
-4x = 16 + 12
Combine like terms: 16 + 12 = 28
-4x = 28
Divide each side by '-4'.
x = -7
Simplifying
x = -7
