how many toothpicks are needed to build the tree on day 100?
Answer:
100 x 4 = 400 - 91 = 309
Step-by-step explanation:
Answer:
100= 4 + 3 (100-1)
4+3 (99)
4 + 297 is 301
Step-by-step explanation:
The first row starts with 4 toothpicks, and they increase by +3 in each row. The first tree is already accounted for which makes the 4 + 3, and why I have 100-1. The teacher said the answer was correct but I doubted the equation. Can you tell me if this is correct?
PLS HELP ME ASAP PLS ILL MARK BRAIN
Answer:
Step-by-step explanation:
1). Let the circumference C and area A of the circle are proportional,
C ∝ A
C = kA
Here k = proportionality constant
k = [tex]\frac{C}{A}[/tex]
From the given table,
For C = 25 cm, A = 50 cm²
Then the value of k = [tex]\frac{25}{50}[/tex]
k = [tex]\frac{1}{2}[/tex]
For C = 50 cm, A = 201 cm²
k = [tex]\frac{50}{201}[/tex] ≈ [tex]\frac{1}{4}[/tex]
In both the cases proportionality constant is giving the different values.
Therefore, Circumference and Area of the circular objects are not proportional.
2). If A = [tex]\frac{1}{2}\times r\times C[/tex]
Then this equation will be true for all the values of r and C given in the table.
For r = 4 cm and C = 25 cm
A = [tex]\frac{1}{2}\times 4\times 25[/tex] = 50 cm²
For r = 8 cm and C = 50 cm
A = [tex]\frac{1}{2}\times 8\times 50[/tex]
A = 200 cm²
True for all values of 'r' and 'C'.

A shoe store by packs of socks wholesale for $5 each and marks up by $40. The store decides to discount the packs of the socks by 40%. Is the discounted price $5.
Answer:
No
Step-by-step explanation:
Price after the socks is marked up = $40 + $5 = $45
If the sock is discounted by 40%, the price of the socks would be 60% of the original price
0.6 x $45 = 27
The discounted price is $27

Solve the equation:
7x − 2 = 26
Answer:
[tex] \large \boxed{x = 4}[/tex]
Step-by-step explanation:
Goal
Solve for x-term.Given
Equation[tex]7x - 2 = 26[/tex]
Step 1
Isolate x by adding 2 to both sides.[tex]7x - 2 + 2 = 26 + 2 \\ 7x + 0 = 28 \\ 7x = 28 \\ x = \frac{28}{7} \\ x = 4[/tex]
Step 2 (Optional)
We check the answer by substituting x = 4 in the equation.[tex]7x - 2 = 26 \\ 7(4) - 2 = 26 \\ 28 - 2 = 26 \\ 26 = 26[/tex]
The equation is true for x = 4. Hence, the solution is x = 4.

what is -7x-3y=-8 if y=-5
Answer:
3.29
Step-by-step explanation:
-7x-3(-5)=-8
-7x+15=-8
-15 -15
-7x=-23
/-7 /-7
x=3.29
Answer:
-1 , replace y by -5 then u will get 15 take to the other side -8-15=-23 then keep x alone divide both sides by -7 so x =3.28

Which set of ordered pairs does not represent a function?
A {(-7,-5),(-5, -7), (-2,5),(-1, -9)}
B {(-6, -7), (5,3), (-7,-8), (3,3)} C{(7,8), (0,6), (0, -8), (-3,7)}
D {(3,5), (1,9), (-5, -6), (4,9)}
Answer:
C
Step-by-step explanation:
Because 0 repeats
The answer is C, because the 0 repeats itself in C and in a function, X does NOT repeat. And in this case, X is 0, which repeats.

A grizzly bear sheds 20% of its weight from hibernation in three weeks, which is 80 pounds. What was the bear’s initial weight?
Answer:
400 pounds
Step-by-step explanation:
Question: 80 is 20% of what?
Formula = a = p* w
w (whole) = a/p
a/p = 80/0.20 (decimal form of 20%)
The initial weight was 400 pounds. It should be the answer so I hope this helps.
