Box A contains only 20-cent coins and Box B contains only 50-cent coins. The number of coins in Box A is twice the number of coins in Box B. The amount of money in Box B is $1.60 more than the amount of money in Box A. How many 20-cent coins are there in Box A?
Answers
Answer: There should be 16, 20 cent coins
Step-by-step explanation:
First we have to do 1.60 x 2 which equals 3.2
Then we divided by 0.20 because the equals the 20 cent coins
We get 16
We can check our work by 0.20 x 16 and that gives us 3.2

8) Solve the exponential equation
Answers
Answer:
5/8 =x
Step-by-step explanation:
2 ^ ( 3x-5) = ( 1/32) ^x
Rewriting 1/32 as 2 ^ -5
2 ^ ( 3x-5) = ( 2^-5) ^x
We know that a^b^c = a^ ( b*c)
2 ^ ( 3x-5) = ( 2) ^-5x
Setting the exponents equal
3x-5 = -5x
Subtract 3x from each side
3x-5-3x = -5x-3x
-5 = -8x
Divide each side by -8
-5/-8 = -8x/-8
5/8 =x
You throw a baseball upward with an initial velocity of 35 feet per second. The height h (in feet) of the baseball relative to your glove is modeled by the position function
h(t) = −16t² + 35t,
where t is the time in seconds. How long does it take for the ball to reach your glove? (Round your answer to one decimal place.)
Answers
Answer:
35/16 sec ( 2 3/16 sec)
Step-by-step explanation:
This assumes you glove is at height = 0
0 = -16t^2 + 35t
0 = t ( -16t + 35) shows t = 0 ( before you throw it) and t = 35/16 sec

Please help!! Thank you!!
Answers
Answer:
-0.182
Step-by-step explanation:
Given expression:
0.46 + (-0.642)It should be noted that;
1. Positive integer + (Negative integer) = Positive integer - Positive integer
a + (-b) = a - b2. Positive integer - (Negative integer) = Positive integer + Positive integer
a - (-b) = a + bOur case is point 1. Therefore,
⇒ 0.46 + (-0.642)⇒ 0.46 - 0.642⇒ -0.182Don drew this diagram of four rectangular pens he wants to build for his four goats. If

many feet of fencing does he need?
(Will give brainliest if you show work)!
Answers
Answer:
So he will need 168 feet of fencing.
Step-by-step explanation:
The perimeter formula of a rectangle is P=(2xL)+(2xW)
The length is 12 and the width is 9.
First, do P=(2x12)+(2x9), P=24+18 P=42 feet
Next, since there are four pens multiply the perimeter of 1 pen by 4.
4x42=168 feet of fencing
So, Don will need 168 feet of fencing.

What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
Let the area of the semicircle be S
Let the total area of the figure be T = S + A
where A = ( 4 )² = 16 cm²
And , S = ( πr² ) / 2
S = 3.14 x ( 2 )² / 2
S = 6.28 cm²
So , the total area T =6.28 cm² + 16 cm² = 22.28 cm²

Answer:
Axis of symmetry: x = 5
Vertex form: y = -4(x - 5)² + 3
Step-by-step explanation:
Given ordered pairs: (2, -33) (3, -13) (4, -1) (5, 3) (6, -1)
Axis of Symmetry
As this is a parabola, it will be symmetrical.
To determine the axis of symmetry, identify two ordered pairs that have the same y-values and find their midpoint.
Two ordered pairs with the same y-value: (-4, 1) and (6, -1)
Midpoint of x = 4 and x = 6 is: x = 5
Therefore, the axis of symmetry is x = 5
Vertex form
Vertex form of a quadratic equation: y = a(x - h)² + k
(where (h, k) is the vertex)
The axis of symmetry is the x-value of the vertex of the parabola.
As we have been given the point when x = 5, the vertex is: (5, 3)
Substituting this into the formula:
⇒ y = a(x - 5)² + 3
To find the value of a, substitute any of the other points into the formula and solve for a.
Using (4, -1)
⇒ a(4 - 5)² + 3 = -1
⇒ a(-1)² = -4
⇒ a = -4
Therefore, the vertex form of the parabola is:
y = -4(x - 5)² + 3
Find the area and circumference of each shaded sector. Use 3.14 for . Round to the
nearest tenth.
Answers
Answer:
Area = 226.1 ft^2
and circumference = 61.7 ft.
Both to the nearest tenth.
Step-by-step explanation:
The area of shaded part
= 1/2 *3.14 r^2
= 1/2 * 3.14 * 12^2 = 226.1 ft^2.
Circumferences of the shaded part = diameter + length of the semicircle
= 2 *r + 3.14 * r
= 2*12 + 3.14 * 12
= 61.68 ft.

What is a quadratic equaton?A quadratic equation is an algebraic expression in the form of variables and constants.
A quadratic equation has two roots as its degree is two.
