L = 882/121 feet
Step-by-step explanation:
Set the appropriate variables in the equation to the given values and solve for the unknown.
[tex]T=2\pi\sqrt{\dfrac{L}{32}}\\\\3=2\left(\dfrac{22}{7}\right)\sqrt{\dfrac{L}{32}} \qquad\text{fill in given values}\\\\ \dfrac{3\cdot7}{44}=\sqrt{\dfrac{L}{32}} \qquad\text{multiply by $\dfrac{7}{44}$}\\\\ \left(\dfrac{21}{44}\right)^2=\dfrac{L}{32}\qquad\text{square both sides}\\\\ \dfrac{32\cdot441}{1936}=L \qquad\text{multiply by 32}\\\\ \boxed{L=\dfrac{882}{121}}\qquad\text{reduce the fraction}[/tex]

the ratio of water to salt is 5/2. How much salt is in a test tube that contains 35ml of water?
Answers
Answer:
14 ml
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
Answer:
14ml

the area of a trapezium is 240 cm² 97 the parallel side is 24 and 36 cm long find the distance between them.
Answers
Answer: 8 cm
=========================================
Work Shown:
A = given area = 240 square cmb1 = one parallel base = 24 cmb2 = the other parallel base = 36 cmh = unknown heightLet's solve for h in the formula below
A = 0.5*h*(b1+b2)
240 = 0.5*h*(24+36)
240 = 0.5*60*h
240 = 30h
30h = 240
h = 240/30
h = 8
The height of the trapezium is 8 cm. This is the distance between the two parallel sides.

Find the measures of the numbered angles in the isosceles trapezoid.
Answers
Answer:
Step-by-step explanation:
in an isocelles trapezoid, we have the properties:
the lower base angles are congruent
the upper base angles are congruent
we have an angle= 44
the angle #3= 44 because of the properties
so the lower base angles are equal and equal to 44
sum of the angles in trapezoid=360
360-(44*2)=360-88=272
upper base angles are equal
272/2=136
angle1=angle2=136

38% of what number is 57?
Answers
38 percent of 150 is 57 so the number is 150.
We have,
Let the number be M
From the given condition make an expression to find the number.
38% of M = 57
38/100 x M = 57
Multiply 100/38 on both sides.
M = 57 x 100 / 38
Simplify the numbers.
M = 5700/38
M = 150
Cross-checked to see whether the number is true or not.
38% of 150
38/100 x 150
38/10 x 15
38/2 x 3
19 x 3
57
This is true.
Thus,
38 percent of 150 is 57 so the number is 150.

A 70 Kg man on a 10 kg bike has 1440 J of kinetic energy. How fast is the
man moving?
Answers
9514 1404 393
Answer:
6 m/s
Step-by-step explanation:
The formula for kinetic energy is ...
KE = (1/2)mv² . . . . m is mass
Filling in the given values, we can solve for v.
1440 J = (1/2)(70+10 kg)v^2
(1440 J)/(40 kg) = v^2 = 36 m²/s² . . . . m is meters
v = √(36) m/s = 6 m/s
The man is moving at 6 meters per second.

Answer: X + 11 = 5x - 25
x+11=5x−25
Step 1: Subtract 5x from both sides.
x+11−5x=5x−25−5x
−4x+11=−25
Step 2: Subtract 11 from both sides.
−4x+11−11=−25−11
−4x=−36
Step 3: Divide both sides by -4.
−4x/−4=−36/−4
Answer:
x = 9
Step-by-step explanation:
Let's solve your equation step-by-step.
x+11=5x−25
Step 1: Subtract 5x from both sides.
x+11−5x=5x−25−5x
−4x+11=−25
Step 2: Subtract 11 from both sides.
−4x+11−11=−25−11
−4x=−36
Step 3: Divide both sides by -4.
−4x/-4 = -36 /-4

Quadratic formula to find the values of x that are solutions to the equation 2x2 + 3x + 1 = 0
Answers
Answer:
x = -0.5 or -1
Step-by-step explanation:
Given the quadratic equation;
2x² + 3x + 1 = 0
The standard form of a quadratic equation is ax² + bx + c = 0
Therefore, a = 2, b = 3 and c = 1
Quadratic equation formula is;
[tex] x = \frac {-b \; \pm \sqrt {b^{2} - 4ac}}{2a} [/tex]
Substituting into the equation, we have;
[tex]x = \frac {-3 \; \pm \sqrt {3^{2} - 4*2*1}}{2*2}[/tex]
[tex]x = \frac {-3 \pm \sqrt {9 - 8}}{4}[/tex]
[tex]x = \frac {-3 \pm \sqrt {1}}{4}[/tex]
Simplifying further, we have;
[tex]x = \frac {-3 \pm 1}{4}[/tex]
[tex]x_{1} = \frac {-3 + 1}{4}[/tex]
[tex]x_{1} = \frac {-2}{4}[/tex]
[tex]x_{1} = -0.5[/tex]
To find the value of x2;
[tex]x_{2} = \frac {-3 - 1}{4} \\x_{2} = \frac {-4}{4} \\x_{2} = -1[/tex]
Therefore, the value of x = -0.5 or -1
