What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags
The equation can be written as,
L + M + S = 440
L = 2M
2M + M + 30 = 440
3M = 410
M = 410 / 3
Therefore, the number of medium bags will be 410 / 3.

how do you solve this 1 1/4 + 1 1/2
Answers
Answer:
your answer for 11/4+11/2 would be 8.25
Step-by-step explanation:
Answer:
1 1/4 + 1 1/2 = 2 3/4
Step-by-step explanation:
first do 1/4 plus 1/2 to solve that you need the same denominator. To get the same denominator you have to see which number they both go into equally, 4 goes into 4 once and 2 goes into 4 twice, meaning you can make both denominators 4. 2 * 2 = 4 and if you do something to the denominator you have to do it to the numerator, so 1/2 would become 2/4. 1/4 plus 2/4 is 3/4. now move onto the whole numbers 1+1=2. so, the answer must be
2 3/4. hope this helps

How many ounces of coffee can be bought for $1.11 if 2 pounds of coffee costs $5.92
Answers
Answer:
6 Ounces!
Step-by-step explanation:
$ 5.92 you get 2 pounds
1.11 you will get 2*1.11/5.92
= 0.375 pounds
1 pound = 16 ounzes
0.375 pounds = 16*0.375
= 6 ounces
Hope I helped !
The 6 ounces of coffee you can buy for $1.11 if 2 pounds of coffee costs $5.92 the answer is 6 ounces.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
2 pounds of coffee costs $5.92
Let x be the amount of coffee you get in $1.11
The proportion will be equal:
2/x = 5.92/1.11
To get the value of x,
On cross multiplication:
2×1.11 = 5.92x
5.92x = 2.22
x = 2.22/5.92
x = 0.375 pounds
As we know,
1 pound = 16 ounces
0.375 pounds = y ounces
y = 16x0.375
y = 6 ounces
Thus, the 6 ounces of coffee you can buy for $1.11 if 2 pounds of coffee costs $5.92 the answer is 6 ounces.

The square has side length 16cm.
Find the area of the logo that is white.
Answers
The white area of the square is equal to 55.04cm²
How to calculate the white area of the square?To calculate the white area of the square we must perform the following operations.
Calculate the total area of the squareTo calculate the total area of the square, we multiply the side length by the base.
16cm × 16cm = 256cm²Then we must calculate the area of the pink circles, for this we use the following formula:
A = Π × r²Then we proceed to replace the values of the number pi and the radius:
A = 3.14 × 4²A = 3.14 x 16A = 50.24cm²Now we multiply the area of the circle by four to find the total area occupied by the four circles inside the square.
50.24cm² × 4 = 200.96cm²
Finally we subtract the area of the 4 circles from the total area of the square and the result will be equivalent to the white area of the square.
256cm² - 200.94cm² = 55.04cm²

Explanation:
Solve f[g(6)] by finding f(x) when x = g(6).
Find g(6).
g(x) = x - 8
Set x = 6.
g(6) = 6 - 8
g(6) = -2
Find f[g(6)].
f(x) = 6x + 12
Set x = g(6).
f[g(6)] = 6[g(6)] + 12
Substitute g(6) = -2.
f(-2) = 6(-2) + 12
f(-2) = -12 + 12
f(-2) = 0
Therefore, f[g(6)] is 0.
Answer:
2. 0 or B. 0
Step-by-step explanation:
First you need to find g(6) which is -2 now plug in -2 into the function f. So 6(-2)+12=0

What is Linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The function is,
y = 4x - 1
Now, The graph of function y = 4x - 1 is shown in image.
And, At y = 1;
By the graph the value of x = 1/2.
And, In mathematically;
At y = 1
The value of x is;
y = 4x - 1
1 = 4x - 1
4x = 2
x = 2/4
x = 1/2
Thus,
a) The graph of y = 4x - 1 is shown in attached image.
b) By using the graph at y = 1 the value of x is 1/2.

answer this its about the 8 side shapee
Answers
Answer:
A = 42 - 80 B = 40 - 112
Step-by-step explanation:
I can answer Both A & B for you however C & D aren't very clear.
A:
Perimeter = 42cm
Area = 80cm Cubed
B:
Perimeter = 40cm
Area = 112cm Cubed
Calculations
In Question A, you are given all the measurements for the perimeter except, which is the line at the bottom. If we take what we already have been given.
10 + 8 + 4 + 4 + 3
We have 3 sides currently without a measurement, The Right side of the shape is 8, therefore the left must be the same, so that measurement is 8.
The small line creating the indent inside the shape must be 2, as we know the line at the top = 10cm. The line opposite it is must be 3 as the one opposite is 3cm.
Factoring those into our calculation:
10 + 8 + 8 + 4 + 4 + 3 + 3 + 2 = 42cm (Perimeter)
To find the Area you multiply the Height of the shape by the width.
Height = 8
Width = 10
8 x 10 = [tex]80cm^{2}[/tex] (Area)
In Question B, you are given all the measurements for the perimeter, so you would simply add them up again.
14 + 10 + 8 + 2 + 6 = 40cm (Perimeter)
To Calculate the Area as previously said you would multiply the width by height.
Height = 8cm
Width = 14
14 x 8 = [tex]112cm^{2}[/tex] (Area)
Hope this helps :)
