Step-by-step explanation:
Simplify 20/55;
[tex] \frac{20 \div 5}{55 \div 5} = \frac{4}{11} [/tex]
[tex] \frac{2}{5} \: is \: not \: equivalent \: to \: \frac{4}{11} [/tex]
In order for 2/5 to be equivalent with 20/55, it has to be an unsimplified form of the ratio 2/5. We can identify that 20/55 isn't.
Assuming 2:5 and 22:55 are equivalent. Then;
[tex]\implies 2:5 = 20:55[/tex]
This can be checked by using two methods. Listed below!
Method 1 (As stated above):This method has been used in the above answer. The above answer has simplified the right-hand-side and verified that the ratios are not equivalent.
Obtained ratio:
[tex]2:5 = 20:55[/tex]
We can see that 20 and 55 are divisible by 5. Therefore, we can divide 5 to the numerator and the denominator to simplify the fraction.
[tex]2:5 = (20 \div 5):(55 \div 5)[/tex]
[tex]2:5 = (4):(11)[/tex]
Therefore, the given ratios are NOT equivalent.
Method 2:To determine if the ratios are equivalent (or not);
Multiply the extremes (Refer to notes) of the ratio and isolate them on one side of the equation.Multiply the middles (Refer to notes) of the ratio and isolate them on the other side of the equation.Therefore,
[tex]\implies 2:5 = 20:55[/tex]
[tex]\implies 2 \times 55 = 5 \times 20[/tex]
Now, let's simplify both sides of the equation.
[tex]\implies 2 \times 55 = 5 \times 20[/tex]
[tex]\implies 110 = 100 \ \ \ (\text{False})[/tex]
Therefore, the given ratios are NOT equivalent, as stated in method 1.
Notes:Extremes: (a : b = c : d) ⇒ "a" and "d"Middles: (a : b = c : d) ⇒ "b" and "c"Learn more about equivalent ratios: https://brainly.com/question/18835388
Seventy-five percent of the apple pies were sold on Tuesday, and the remainder were thrown out. If 12 apple ples were sold Tuesday, then how many were thrown out?
Answer:
4 pies
Step-by-step explanation:
Hello!
We know that 12 apple pies are 75 percent of the total apple pies.
Let x = # of pies total.
This means that 75% of x, or 0.75x is 12
Solve:
75% of x = 120.75x = 12x = 16Now, 16 is the total number of pies. To find the number thrown out, we subtract 12.
16 - 12 = 4
4 pies were thrown out
Solution:
Let "a" represent total apple pies.
Note that:
75% x a = 12 apples piesSimplify the LHS:
75a/100 = 12 apple piesUse cross multiplication:
75a = 12 x 100=> 75a = 1200Divide 75 both sides:
=> 75a/75 = 1200/75=> a = 16If there were 16 apples and 12 were sold, 4 apple pies were thrown out.
He collected a total of 225 . If 68% of the stamps he collected were foreign, how many other stamps did he collect?
Answer:
72 stamps
Step-by-step explanation:
First, we're looking to find the number of stamps that AREN'T foreign, so we have to subtract 68% from 100%.
100% - 68% 32%Now, we know that 32% of the stamps are NOT foreign. So, next, we:
Multiply 32 by 225.Divide the product of 32 and 225 by 100[tex]32*225[/tex] [tex]7200[/tex] [tex]7200/100[/tex] [tex]72[/tex]Therefore, the answer is 72 stamps.

What is the surface area of this triangular pyramid? 7 in 4 in 4 in 4 in 3.5 in
Answer:
37 yd²
Step-by-step explanation:
The computation of the surface area of this triangular pyramid is shown below:
The surface area of this triangular pyramid is
But before that
Lateral area = 3(1 ÷ 2) × base × height
= (3 ÷ 2)(4 yd)(5 yd)
= 30 yd²
Now
base area = 1 ÷ 2 × base × height
= 1 ÷ 2(4 yd)(3.5 yd)
= 7 yd²
Now the total surface area is
surface area = lateral area + base area
= 30 yd² + 7 yd²
= 37 yd²
Answer:

m + s = 26
3m + 8s = 123
Answer:
M=17
S=9
Step-by-step explanation:
m = 17 and s = 9
Refer to the attachment for full solution . The main key here is to multiply first equation by 3 so that in both equations the coefficient of m will be same so that we can eliminate 3m and then we will solve for s and then putting value of s in any of the equation , so we can get m
Note :- You can multiply the 1st equation by 8 too for making coefficient of s same and then solving for m and then solving for s
What is the area of this polygon?????? Pls
Answer:
39
Step-by-step explanation:
Draw a line from V to R. That gives you a triangle MVR
The height of the triangle = 3
The base of the triangle = 6
Area Triangle = 1/2 * 3 * 6 = 9
The figure left over is a rectangle
Area = VR * VE
VR = 6
VE = 5
Area = 6*5 = 30
Total area = 39
Answer:
We can split this figure into two shapes;
A triangle, and a rectangle.
If we split the figure from 'V' to 'R', it will formulate the two shapes I mentioned.
First, we must know the formula for the area of a triangle -
A = BH x 1/2
Where B represents the base, and H serves as the height.
For the triangle, the height is 3, and the base is 6.
So we plug in these values into our formula:
A = BH
A = 6(3) x 1/2
A = 18 x 1/2
A = 18/2
A = 9
Now the formula for the area of a rectangle:
A = LW
Where L displays as the length, and W illustrates the width.
Our width of the following rectangle is 6, while our length is 5.
Plug in our values into the formula:
A = LW
A = 5(6)
A = 30
Now, we add our areas;
9 + 30 = 39 square units, is our answer.
