Divide 16 by two to get the diameter: 8
Square 8: 64
Since the answer is in terms of pi, the answer is 64[tex]\pi[/tex]
Answer:
64 π
Step-by-step explanation:
Diameter = 16 inches
Radius = 16/2 = 8 inches
Area of circle = πr²
= π(8)²
= 64 π sq inches

Simplify (2^-1 +5^-1)^2 *(-5/8)^-2
Answer: 1.2544
Step-by-step explanation:
2^-1 = 1/2
5^-1 = 1/5
1/2+1/5 = 7/10
(7/10)^2=49/100=0.49
(-5/8)^-2 = 64/25=2.56
(2^-1 +5^-1)^2 *(-5/8)^-2 = 0.49 * 2.56 = 1.2544
Solve each proportion
Answer:
[tex] \frac{11}{b - 1} = \frac{6}{b + 1} \\ 11(b + 1) = (b - 1).6 \\ 11b + 11 = 6b - 6 \\ 11b + 11 - 11 = 6b - 6 - 11 \\ 11b - 6b = 6b - 17 - 6b \\ 5b = - 17 \\ \frac{5b}{5} = \frac{ - 17}{5} \\ b = \frac{ - 17}{5} \\ b = - 3.4[/tex]
[tex]\boxed{\underline{\bf \: Answer}}[/tex]
[tex] \sf \frac{11}{b + 1} = \frac{6}{b + 1} \\ [/tex]
Multiply both sides of the equation by [tex]\left(b-1\right)\left(b+1\right)[/tex], the least common multiple of b-1,b+1.
[tex]\sf\left(b+1\right)\times 11=\left(b-1\right)\times 6 [/tex]
Use the distributive property to multiply b+1 by 11.
[tex]\sf11b+11=\left(b-1\right)\times 6 [/tex]
Subtract 6b from both sides.
[tex]\sf11b+11-6b=-6 [/tex]
Combine 11b and -6b to get 5b.
[tex]\sf5b+11=-6 [/tex]
Subtract 11 from both sides.
[tex]\sf5b=-6-11 [/tex]
Subtract 11 from -6 to get -17.
[tex]\sf5b=-17 [/tex]
Divide both sides by 5.
[tex]\sf \: b=\bf\frac{-17}{5} [/tex]
=> The correct answer is [tex]\bf \: b=\frac{-17}{5} [/tex] or [tex]\bf \: b= -3.4 [/tex] (✓).

1/2x-3/10=5/2x+7/10
Answer:
-Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x= -1/2
Decimal Form:
x=0.5
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer: x = -1/2
Step-by-step explanation:
1/2 x - 3/10 = 5/2 x + 7/10
-1/2 x on both sides
-3/10 = 4/2 x +7/10
subtract 7/10 from both sides
-1 = 4/2x
simplify
2x = -1
divide 2 on both sides
x = -1/2

Midpoints & endpoints
Answer:
The coordinates of A are (1, -4)
Step-by-step explanation:
The formula for finding a midpoint is ((x1 + x2) / 2, (y1 + y2) / 2)
However, in this problem, we're already given the midpoint. We're trying to find an endpoint. So, the equation changes into:
((x + 9) / 2 = 4, (y + 0) / 2 = -2)
For the x and y coordinates, multiply both sides by 2
(x + 9 = 8, y = -4)
(x = -1, y = -4)
Rewrite as coordinates.
(-1, -4)

The third answer
1 quarter, 6 dimes, 1 nickel, 7 pennies
14 +3n = 8n - 3(n - 4)
Answer:
n=1
Step-by-step explanation:
Start by distributing the -3 to (n-4)
14+3n=8n-3n+12
Then combine like terms on the right
14+3n=5n+12
Subtract 12 from both sides
2+3n=5n
Subtract 3n from both sides
2=2n
Divide both sides by 2

Question 6 options:
x = 10
x = 4
x = −14
x = −17
Answer:
B. x = 4
Step-by-step explanation:
Answer: X = 4
Step-by-step explanation:
(x + 20)/2 = 3x
x + 20 = 2*3x
x + 20 = 6x
20 = 6x - x
20 = 5x
20/5 = x

In triangle ADE:
sum of all angles is 180.
3x-10+58+42=180
3x+90=180
3x=180-90
3x=90
x=90/3
x=30
As line DA and CB are parallel:
angle D=angle C
angle y=58
In angle BCE, sum of angles is 180.
z+58+42=180
z+100=180
z=180-100
z=80

solve for X: -0.6x>3
Answer:
x < -5
Step-by-step explanation:
-0.6x > 3
=> Dividing 0.6 on both sides
=> -x > 3/0.6
=> -x > 5
=> x < -5 [When we multiply -1 on both sides the sign changes]
The solution to the inequality -0.6x > 3 is x < -5.
To solve for x in the inequality -0.6x > 3, we need to isolate x on one side of the inequality.
First, to divide both sides of the inequality by -0.6 to remove the coefficient in front of x.
Remember that when dividing or multiplying both sides of an inequality by a negative number, we need to reverse the inequality sign.
So, dividing both sides by -0.6 gives
x < 3 / -0.6
Simplifying the right side of the inequality, we have:
x < -5
Therefore, the solution to the inequality -0.6x > 3 is x < -5.

Find the length of "c" to the
nearest tenth using the
Pythagorean Theorem.
Enter
Answer:
10.6
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Where a and b = the legs and c = hypotenuse
We are given two legs and need to find the hypotenuse
Given:
Short leg (a) = 7
Long leg (b) = 8
Hypotenuse = c
Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c
Pythagorean theorem: a² + b² = c²
a = 7, b = 8, c = c
Plug in values
7² + 8² = c²
Now solve for c
Simplify exponents
49 + 64 = c²
Add
113 = c²
Taking the square root of both sides
c = 10.6 ( rounded to the nearest tenth )
Answer:
c = 10.6
Step-by-step explanation:
[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]
