In circle D with m \angle CDE= 60m∠CDE=60 and CD=3CD=3 units, find the length of arc CE. Round to the nearest hundredth
Answer:
Length of arc CE = 3.14 unit (Approx.)
Step-by-step explanation:
Given:
Radius of circle = 3 units
Angle between radius = 60°
Find:
Length of arc CE
Computation:
Length of arc = [θ/360][2πr]
Length of arc CE = [60/360][2(2/7)(3)]
Length of arc CE = [60/360][2(3.14)(3)]
Length of arc CE = [1/6][6(3.14)]
Length of arc CE = 3.14 unit (Approx.)

What is 2/5 y + 1/5 x -0.2y-6+(-2)
Answer:
[tex]\frac{y}{5} + \frac{x}{5}-8[/tex]
Step-by-step explanation:
1) Simplify 2 /5y to 2y/5.
[tex]\frac{2y}{5} + \frac{1}{5} x-0.2 y-6-2[/tex]
2) simplify 1/5x to x/5.
[tex]\frac{2y}{5} +\frac{x}{5} -0.2y-6-2[/tex]
3) Collect like terms.
[tex](\frac{2y}{5} -0.2y) + \frac{x}{5} +(-6-2)[/tex]
4) Simplify.
[tex]\frac{y}{5}+ \frac{x}{5} -8[/tex]
Therefor, the answer is y/5 + x/5 -8.
HELP ASAP!!!!! A circle is shown. Secant A D and tangent E D intersect at point D outside of the circle. Secant A D intersects the circle at point B. The length of A B is a, the length of B D is 10, and the length of D E is 12.
Which equation results from applying the secant and tangent segment theorem to the figure?
12(a + 12) = 102
10 + 12 = a2
10(a + 10) = 122
10(12) = a2
Answer:
C)
10(a + 10) = 12 2
Applying the secant-tangent segment theorem, the equation that will result using the figure given is: C. 10(a + 10) = 12².
What is the Secant-tangent Segment Theorem?The secant-tangent segment theorem states that if a tangent and a secant intersect at a point outside a circle, then the square of the measure of the products of the secant segment and its external secant segment equals the square of the measure of the tangent segment.
Thus, using the figure given, the equation that results from applying the secant-tangent segment theorem would be: C. 10(a + 10) = 12²

x = 190 and x = 126
Step-by-step explanation:
In both diagrams the indicated angles are vertical and congruent, then
[tex]\frac{x}{2}[/tex] = 95 ( multiply both sides by 2 )
x = 190
and
x + 21 = 147 ( subtract 21 from both sides )
x = 126

Step-by-step explanation:
Emily has 6 gallons of water josh has 23 quarts of water. How many more points does Emily have more than josh
Answer:
2 pints
Step-by-step explanation:
To determine the amount of pints that Emily has more than Josh, gallons and quarts have to be converted to pints and the value is then subtracted
1. Convert gallons and quarts to pints
1 gallon = 8 pints
6 gallons = 8 x 6 = 48 pints
1 quart = 2 pints
23 quarts = 2 x 23 = 46 pints
2. Determine the difference in the amount of pints Emily has and the amount Josh has
48 pints - 46 pints = 2 pints

Answer:
x=4
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
24−4x=2x
24+−4x=2x
−4x+24=2x
Step 2: Subtract 2x from both sides.
−4x+24−2x=2x−2x
−6x+24=0
Step 3: Subtract 24 from both sides.
−6x+24−24=0−24
−6x=−24
Step 4: Divide both sides by -6.
−6x /−6 = −24 /−6
x=4

Area = πr²
So, we have:
Area = 3.14 * 88²
Evaluate
Area = 24316.16

Omari buys a computer for $1,083. She
makes a down payment of 20%. She pays
$144.40 per month to finish paying for
the computer. How many months will it
take Omari to finish paying?
Answer:
6 months.
Step-by-step explanation:
To find the answer, we first need to find out how much Omari paid for the down payment. To find this, you multiply 1083*0.20 and you get $216.60. So we subtract the down payment from the total leaving us with $866.40. Now to find out how many months it would take Omari to pay, we divide 866.40/144.40 since each month she pays $144.40 a month. Once you divide 866.40/144.40, you are left with an answer of 6 months.
