Answer:
The first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm,
and the fourth side is 11.5cm × 6 = 69cm.
Step-by-step explanation:
A quadrilateral is a 4 sided shape, while perimeter is the addition of all the sides of the quadrilateral. Since the sides of the quadrilateral is not stade, assume the sides of the quadrilateral is x, therefore 1:2:3:6 = x:2x:3x:6x. The total ratio is x+2x+3x+6x=12x, therefore 12x= 138 , x = 11.5cm, Therefore the first side is 11.5cm, the second is 11.5cm×2 = 23cm, the third is 11.5cm × 3 = 34.5cm, and the fourth is 11.5cm × 6 = 69cm.

If f(x)=3x^2-7x find f(-2)
Answer:
f(-2) = 26
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightAlgebra I
Function NotationStep-by-step explanation:
Step 1: Define
f(x) = 3x² - 7x
f(-2) is x = -2
Step 2: Evaluate
Substitute in x: f(-2) = 3(-2)² - 7(-2)Exponents: f(-2) = 3(4) - 7(-2)Multiply: f(-2) = 12 + 14Add: f(-2) = 26What is the value of a if a is equal to a×a×a=a+a+a
Answer:
a = ±sqrt(3)
Step-by-step explanation:
a×a×a=a+a+a
Simplifying each side
a^3 = 3a
Divide each side by a
a^3 /a = 3a/a
a^2 = 3
Take the square root of each side
sqrt(a^2) = ±sqrt(3)
a = ±sqrt(3)
Answer:
nope its not equal
a×a×a=a³, but a+a+a=3a
so, a³≠3a

Declan wants to mail 28 drawings to his Grandma. If he can fit 3 drawings in each envelope, how many envelopes will he need to mail all the drawings
Answer:
10 envelopes
Step-by-step explanation:
What we know:
- There are 3 drawings for each envelope
- There are 28 drawings in total
To find out the number of envelopes Declan would need, we divide 28 by 3 (check the picture attached).
28÷3=9 R1
28 divided by 3 gives us 9 with a remainder of 1, which means if Declan had 9 envelopes, he would be able to fit 3 drawings in each with 1 drawing left over. He would need a 10th envelope to use for the last drawing.
Therefore, Declan would need 10 envelopes to mail all the drawings to his grandma.
I hope this helps! Happy holidays :)

solve tje equation for t. Round the answer off to two places after the decimal point.
a group of biologists is surveying the mice population in a forest. the equation n=75^t gives the total number of mice,n, t years after the survey began. what does the number 3 mean in this situation.
1. the common difference
2. the total population
3. the common ratio
4. the slope
Complete question is;
A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.
what does the number 3 mean in this situation.
1. the common difference
2. the total population
3. the common ratio
4. the slope
Answer:
3 is the common ratio
Step-by-step explanation:
We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.
Normally, formula when calculating population growth takes an exponential function;
n = n_o(e^(rt))
Or in this our case, it can be written as;
n = n_o((e^(r))^(t))
Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3
Where r is the growth rate.
e is exponential constant.
Thus, we can say that 3 is the common ratio
The circumference of a circular tablecloth is 160 inches, Will the tablecloth cover
a table with diameter 52 inches?
Answer:
D= 50.92 in
Step-by-step explanation:
Step one:
Given data
The circumference of a circular tablecloth is 160 inches
We want to know if the circular table cloth can also cover a table of diameter 52 in
Step two:
let us solve for the diameter of the table cloth given that the circumference is
160in
circumference
[tex]C= 2 \pi r[/tex]
[tex]160= 2*3.142*r\\\\160= 6.284r[/tex]
divide both sides by 6.284
[tex]160/6.284= r\\\\r=25.46 in[/tex]
The diameter of the table cloth is
[tex]=25.46*2\\\\=50.92 in[/tex]
The Table cloth cannot cover the table because the diameter of the cloth is not up to the diameter of the table
First method: Multiply the equation for bouquet A by , and add it to the equation for bouquet C. Then multiply the equation for bouquet B by , and add it to the equation for bouquet C. Second method: Rewrite the equation for bouquet B by subtracting from both sides of the equation. Then divide both sides by , and substitute the expression for in the equations for bouquets A and C.

Anton has 3 8/7 cups of syrup that he serves with his pancake orders. He uses 2/3 cup of syrup for each pancake order. What is the maximum number of complete pancake orders that Anton can serve with the syrup he has?
Answer:
6 3/14 pancake order s
Step-by-step explanation:
The question above is calculated as:
2/3 cup of syrup = 1 pancake order
3 8/7 cups of syrup = x
Cross Multiply
2/3 × x = 3 8/7 × 1
x = 3 8/7 ÷ 2/3
x = 29/7 ÷ 2/3
x = 29/7 × 3/2
x = 87/14
x = 6 3/14 order
The maximum number of complete pancake orders that Anton can serve with the syrup he has is 6 3/14 pancake orders

A recipe calls for 3 cups of sugar and 9 cups of water. How many should be used with 2 cups of sugar?
Answer:
6 cups of water
Step-by-step explanation:
A recipe calls for 3 cups of sugar and 9 cups of water. How many should be used with 2 cups of sugar?
The question above, is solved below:
3 cups of sugar = 9 cups of water
2 cups of sugar = x
Cross Multiply
3x = 9 × 2
x = 18/3
x = 6
Hence, 2 cups of sugar = 6 cups of water

Susan wanted to share her 37 seashells with her two younger brothers. If she divided her seashells between the three of them, how many would each person get?
Given :
Susan wanted to share her 37 seashells with her two younger brothers.
To Find :
If she divided her seashells between the three of them, how many would each person get.
Solution :
Let, each person will get x seashells.
So,
[tex]x = \dfrac{\text{Total number of seashells}}{\text{Number of persons}}\\\\x = \dfrac{37}{3}\\\\x = 12.333[/tex]
But as we know seashells cannot be in decimal.
Therefore, each person will get exactly 12 shells.
