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'.

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

Answer:
P(Red) = 0.44
Step-by-step explanation:
There are 3 (mutually exclusive) ways to get red. The probability of red is the sum of the probabilities of the different ways to get there:
P(red) = (0.35)(0.6) + (0.45)(0.2) + (0.20)(0.7) = 0.21 + 0.09 + 0.14 = 0.44
The probability a player will select a red ball is 0.44.

Two hundred dollars is increased by 25% and the result decreased by 25%
What is the final result?
Answer:
If $200 increased by 25%, your result would be $250
If it then decreased by 25%, your result would be $187.5
Step-by-step explanation:
Multiply 200 and 25% and add 200 to get 250
Multiply 250 and 25% and then add that value to get 187.5
Answer:
187.5
Step-by-step explanation:
200*1.25=250 (this shows the increase by 25%)
250*.75=187.5 (this shows the decrease by 25%)

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.
