Answer:
5.49 inches[tex] \: [/tex]
Step-by-step explanation:
It is given that, The circumference of a circle is 34.48 inches and we are to find the radius of the circle.[tex] \: [/tex]
To find the radius of the circle we must know this formula first :
[tex]\\{ \longrightarrow \qquad{ \underline {\boxed{ \pmb{ \mathfrak{ \: 2 \pi r \: =Circumference_{(circle)}}}}}}} \: \: \bigstar \\ \\[/tex]
Now substituting the values in the formula :
[tex]\\{ \longrightarrow \qquad{ {{ \tt{ \: 2 \times 3.14 \times r \: =34.48}}}}} \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ {{ \tt{ 6.28 \times r \: =34.48}}}}} \\ \\[/tex]
[tex]{ \longrightarrow \qquad{ {{ \tt{ r \: = \frac{34.48}{6.28} }}}}} \\ \\ [/tex]
[tex]{ \longrightarrow \qquad{ \pmb {{ \frak{ r \: = 5.490 }}}}} \\ \\ [/tex]
Therefore,
The radius of the circle is 5.49 inches (Rounded to nearest hundredth5 How many balls can Brad put in a box that has 6 x 6 balls in the bottom layer and 5
layers? Show your work.
A product is the outcome of multiplication. Brad can put 144 balls in the box.
What is multiplication?A product is the outcome of multiplication or an expression that indicates the elements that will be multiplied.
Given that the bottom layer of the box has 6×6 balls, while the box has 5 layers. Since one layer is already arranged, therefore, there are only 4 layers left in which each layer will have 6×6 balls. Therefore, the total number of balls is,
[tex]\text{Total number of ball} = 4 \times 6\times 6 = 144[/tex]
Hence, Brad can put 144 balls in the box.

Which point is not on the graph of the equation: y = 10 + x?
A. (0, 10)
B. (3, 13)
C. (8, 2)
D. (5, 15)
Al the points except (8, 2) will give us a true equation when substituted into the equaton, so, (8, 0) is not the graph of the equation.
What is a Point on a Graph of an Equation?Any coordinate point on a graph represented by an equation will give a true equation if the points are plugged into the equation and evaluated.
(8, 2) is not on the graph of y = 10 + x because substituting x = 8 and y = 2 into the equation will give us:

Answer:
Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 64
Step-by-step explanation:
Information
Domain: set of all possible input values (x-values)
Range: set of all possible output values (y-values)
From inspection of the diagram, the minimum value of x is 0 and the maximum value of x is 4.
Therefore, the domain is: 0 ≤ x ≤ 4
From inspection of the diagram, the minimum value of y is 0 and the maximum value of y is 64.
Therefore, the range is: 0 ≤ y ≤ 64
Remember:-
If a pair be (x,y) then
x is domainy is rangehence
Here x goes from 0 to 4 so domain is

Answer:
∠DBC = 155°
Step-by-step explanation:
Assuming that ABC is a straight line.
Angles on a straight line sum to 180°.
⇒ (2x² + 3x - 2) + ∠DBC = 180°
⇒ ∠DBC = 180° - (2x² + 3x - 2)
The sum of the interior angles of a triangle is 180°:
⇒ (x² + 1) + (4x + 3) + ∠DBC = 180°
⇒ ∠DBC = 180° - (x² + 1) - (4x + 3)
Therefore, we can equate the equations and solve for x:
⇒ ∠DBC = ∠DBC
⇒ 180 - (2x² + 3x - 2) = 180 - (x² + 1) - (4x + 3)
⇒ 180 - 180 = (2x² + 3x - 2) - (x² + 1) - (4x + 3)
⇒ (2x² + 3x - 2) - (x² + 1) - (4x + 3) = 0
⇒ 2x² + 3x - 2 - x² - 1 - 4x - 3 = 0
⇒ x² - x - 6 = 0
⇒ x² + 2x - 3x - 6 = 0
⇒ x(x + 2) - 3(x + 2) = 0
⇒ (x + 2)(x - 3) = 0
Therefore, x = -2, x = 3
As angles are positive, x = 3 only
Substituting found value of x into the angle expressions:
⇒ ∠BDC = x² + 1 = (3)² + 1 = 10°
⇒ ∠DCB = 4x + 3 = 4(3) + 3 = 15°
The sum of the interior angles of a triangle is 180°:
⇒ ∠DBC + ∠BDC + ∠DCB = 180°
⇒ ∠DBC = 180° - ∠BDC - ∠DCB
⇒ ∠DBC = 180° - 10° - 15°
⇒ ∠DBC = 155°

Please help! Area of part of a circle!!!
The sector (shaded segment + triangle) makes up 1/3 of the circle (which is evident from the fact that the labeled arc measures 120° and a full circle measures 360°). The circle has radius 96 cm, so its total area is π (96 cm)² = 9216π cm². The area of the sector is then 1/3 • 9216π cm² = 3072π cm².
The triangle is isosceles since two of its legs coincide with the radius of the circle, and the angle between these sides measures 120°, same as the arc it subtends. If b is the length of the third side in the triangle, then by the law of cosines
b² = 2 • (96 cm)² - 2 (96 cm)² cos(120°) ⇒ b = 96√3 cm
Call b the base of this triangle.
The vertex angle is 120°, so the other two angles have measure θ such that
120° + 2θ = 180°
since the interior angles of any triangle sum to 180°. Solve for θ :
2θ = 60°
θ = 30°
Draw an altitude for the triangle that connects the vertex to the base. This cuts the triangle into two smaller right triangles. Let h be the height of all these triangles. Using some trig, we find
tan(30°) = h / (b/2) ⇒ h = 48 cm
Then the area of the triangle is
1/2 bh = 1/2 • (96√3 cm) • (48 cm) = 2304√3 cm²
and the area of the shaded segment is the difference between the area of the sector and the area of the triangle:
3072π cm² - 2304√3 cm² ≈ 5660.3 cm²

Edward opens up a savings account with $250. The bank gives him an interest rate of 2.8% per year (simple interest). About long will it take for Edward to double his money?
(SHOW WORK!!)
Equation:________________
Answer:_________________
Step-by-step explanation:
The interest I per t years is 2.8% of invested amount P
I = PrtLet the interest amount is same as invested amount, then our equation is
P = Prt or1 = rt or1 = 0.028t 2.8% converted to 0.0028Find the value of t
t = 1/0.028t = 35.71 or roughly 36 yearsAnswer:
Equation: 250(1 + 0.028t) = 500
Answer: 36 years
Step-by-step explanation:
Simple interest formula
A = P(1 + rt)
where:
A = final amountP = principalr = interest rate (in decimal form)t = time (in years)Given:
A = double $250 = $500P = $250r = 2.8% = 0.028Substitute given values into the formula and solve for t:
250(1 + 0.028t) = 500
⇒ 250 +7t = 500
⇒ 7t = 250
⇒ t = 250/7
⇒ t = 35.71428571...
So it will take approximately 36 years for Edward to double his money.

If somebody sells TVs and the formula they use is A = 800 + 200t and A = her total income and t = the amount they sell, how much money will they receive if they sell 9 TVs?
Answer:
$2600
Step-by-step explanation:
It is given that the variables:
A = total income
t = amount of TV they sell.
It is also given that they sold 9 TVs. Plug in 9 for t in the given equation:
A = 800 + 200t
A = 800 + 200(9)
A = 800 + 1800
A = 2600
$2600 is the total amount they will receive if they sell 9 TVs.

The population of organisms is described by the following exponential equation:
P(t) = 18,000*(0.9966)^t
How to get the exponential equation?
The general exponential equation is:
P(t) = A*(b)^t
Where A is the initial value, b depends on the percentage that changes, and t is the variable.
In this case, the population decreases by 3.4%, then we have:
B = 1 - 3.4%/100% = 0.9966
And the initial value is 18,000 organisms, replacing that in the general equation we get:
P(t) = 18,000*(0.9966)^t
This is the equation that represents the population.
