Interest = Principal *Rate * Time
= [tex]\frac{600 * 6 * 10}{100}[/tex]
= $360
∴ The balance will be $600 + 360 = $960
Answer:
the answer is $960

Find The equation of a circle that has it center at (-4,3) and has a radius of 5.
Answer:
A.
Step-by-step explanation:
Center = (a,b) = (-4,3)
So, a = -4, b = 3
Radius = 5
Equation of circle:
[tex](x-a)^2+(y-b)^2 = r^2[/tex]
Putting the givens
=> (x+4)²+(y-3)² = 25
[tex] {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} \\
{(x - (4))}^{2} + {(y + 3))}^{3} = {5}^{2} \\ {(x - 4)}^{2} + {(y + 3)}^{2} = 25[/tex]
Please help me find the volume and explain how you found it in a clear form
Answer:
Let's solve this with 3 calculations
1) Volume of the lower section (highlighted in blue)
3 cm hgt 16 cm long 3 cm wide
Volume = 3 * 3 * 16 = 144 cubic cm
2) Volume of left "block"
Volume = 4 cm hgt * 4 cm long * 3 cm wide =
4 * 4 * 3 = 48 cubic cm
3) Volume of right "block"
length = 16cm - 3 - 4 - 3 = 6 cm
Volume = 4 cm hgt * 6 cm long * 3 cm wide =
4 * 6 * 3 = 72 cubic cm
TOTAL VOLUME = 144 + 48 + 72 = 264 cubic cm

1/3( 5x - 9) = 2( 1/3x + 6) what is x?
Answer:
x = 9
Step-by-step explanation:
→Distribute the [tex]\frac{1}{3}[/tex] to (5x - 9), and the 2 to [tex](\frac{1}{3} x + 6)[/tex]:
[tex]\frac{1}{3}[/tex](5x - 9) = 2( [tex]\frac{1}{3}x[/tex] + 6)
[tex]\frac{5}{3}x[/tex] + 3 = [tex]\frac{2}{3}x[/tex]+ 12
→Subtract [tex]\frac{2}{3}x[/tex] from both sides:
x + 3 = 12
→Subtract 3 from both sides:
x = 9
The value of x from the given equation is 6.
The given equation is 1/3 (5x - 9) = 2(1/3 x + 6).
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 5x/3 - 9/3 = 2x/3 +6/2
5x/3 -3 = 2x/3 +3
5x/3 -2x/3 =3+3
(5x-2x)/3 = 6
3x/3 = 6
x = 6
Therefore, the value of x from the given equation is 6.

Which option is better after 3 years, and what is the difference in earned interest? 1Option 2 earns more interest by $3,581.52. Option 2 earns more interest by $2,396.13. Option 1 earns more interest by $2,396.13. Option 1 earns more interest by $3,581.52.
Answer:
Option 1 earns more interest by $2396.13

The weights of the cars passing over a bridge have a mean 3,550 pounds and standard deviation of 870 pounds. Assume that the weights of the cars passing over the bridge are normally distributed. Use the empirical rule to estimate the percentage of cars over the bridge whose weights are between 1810 and 4420 lbs.
a. 13.5%
b. 81.5%
c. 68%
d. 95%
Mean = 3550
SD = 870
Find P(1810 <x<4420)
z = x -mean / sd
= (1810 - 3550 / 870) < z< (4420 - 3550 / 870)
= -2 <z< 1
Using the -z table -2 = 0.0228 and 1 = 0.8413
Subtract: 0.8413 - 0.0228 = 0.8185 x 100 = 81.85%
Rounding everything may change answer slightly so

Des buys a pack of starbursts that has 3 orange,6 pink , 1 yellow , and 5 red starbursts. She puts the candy in the bowl. If she reaches in and grabs two starbursts without putting one back , what is the probability that she will pick a pink and then a yellow?
Answer:
3/70
Step-by-step explanation:
3 orange,6 pink , 1 yellow , and 5 red = 15
P(pink) = number of pink/ total = 6/15 = 3/5
Then without putting it back
3 orange,5 pink , 1 yellow , and 5 red = 14
P(yellow) = number of yellow/ total = 1/14
P(pink, no replacement, yellow) = 3/5*1/14 = 3/70

Given that tan theta = -9/4, where 270° ≤ theta ≤ 360° a)state the 5 trigonometric ratios as a fraction b) determine the value of theta to the nearest degree
Answer:
Step-by-step explanation:
θ lies in 4th quadrant.
cos θ and sec θ are positive all other trigonometric ratios are negative.
sin θ/cos θ=-9/4
sin θ=-9/4 cos θ
we know sin² θ +cos ² θ =1
(-9/4 cos θ)²+cos ² θ =1
cos ² θ (81/16+1)=1
cos ²θ((81+16)/16)=1
cos² θ=16/97
cos θ=4/√97
sin θ=-9/4*4/√97=-9/√97
sec θ=1/cos θ=√97/4
cosec θ=1/sin θ=-√97/9
cot θ=1/tan θ=-4/9
[tex]\ theta=tan^{-1}(-9/4) \approx 294 ^\circ[/tex]

What two number multiply to -21 and add to 20
Answer:
-1 and 21
Step-by-step explanation:
Let the numbers be x and y.
x + y = 20
xy = -21
Solve the first equation for x and substitute in the second equation.
x = 20 - y
(20 - y)y = -21
20y - y^2 = -21
y^2 - 20y - 21 = 0
(y - 21)(y + 1) = 0
y - 21 = 0 or y + 1 = 0
y = 21 or y = -1
For y = 21:
x = 20 - y
x = 20 - 21
x = -1
For y = -1:
x = 20 - y
x = 20 - (-1)
x = 21
Solutions: (-1, 21) and (21, -1)
Answer: the numbers are -1 and 21

A study shows that 35% of the fish caught in a local lake had high levels of mercury. Suppose that 10 fish were caught from this lake. Find, to the nearest tenth of a percent, the probability that at least 6 of the 10 fish caught did not contain high levels of mercury.
Answer:
0.985
Step-by-step explanation:
Given: 35% of the fish caught in a local lake had high levels of mercury.
To find: probability that at least 6 of the 10 fish caught did not contain high levels of mercury
Solution:
Probability refers to chances of occurrence of some event.
Probability = number of favourable outcomes/Total number of outcomes
Let A denotes the event that the fish caught in a local lake had high levels of mercury.
As 35% of the fish caught in a local lake had high levels of mercury,
[tex]P(A)=0.35[/tex]
Probability that at least 6 of the 10 fish caught did not contain high levels of mercury = 1 - probability that 4 of the 10 fish caught contain high levels of mercury = [tex]1-(0.35)^4=1-0.015=0.985[/tex]

Maya spent her allowance on playing an arcade game a few times and riding the Ferris wheel more than once. Write about what additional information you would need to create a two-variable equation for the scenario. What kind of problem could you solve with your equation?
Answer:
You would need to know how much money she spent and how much she had left.
Step-by-step explanation:
With this, you could find out how much money she had in total.
Sample Response:
To write a two-variable equation, I would first need to know how much Maya’s allowance was. Then, I would need the cost of playing the arcade game and of riding the Ferris wheel. I could let the equation be cost of playing the arcade games plus cost of riding the Ferris wheel equals the total allowance. My variables would represent the number of times Maya played the arcade game and the number of times she rode the Ferris wheel. With this equation I could solve for how many times she rode the Ferris wheel given the number of times she played the arcade game.

- [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
Here [ a, b ] = [ - 8, 2 ] , thus
f(b) = f(2) = - 4 ← read from graph
f(a) = f(- 8) = 1 ← read from graph, thus
average rate of change = [tex]\frac{-4-1}{2-(-8)}[/tex] = [tex]\frac{-5}{10}[/tex] = - [tex]\frac{1}{2}[/tex]

Which inequality represents all the solutions of 10(3x + 2) > 7(2x − 4)?
Answer:
x>-3
Step-by-step explanation:
Answer:
x > -3
Step-by-step explanation: First you have to distribute the 10 to 3x +2 and 7 to 2x -4 . 10 times 3x + 2 is 30x + 20. 7 times 2x -4 is 14 x -28 . Subtract 20 from both sides, which is 30x = 14x-48 , because -28 minus 20 is -48. Subtract 14 x from both sides which is gonna be 16x >-48 , divide both sides by 16 which is x > -3.
