Answer:
20 home runs left to hit.
Step-by-step explanation:
Ok so 100%/20% is 5. Increment 5 home runs until you get to 100%. So, 20% =5, 40% = 10, 80% = 15, and 100% = 20
Answer: 25 home runs
Step-by-step explanation:
20% = 5
40% = 10
80% = 20
80% + 20% = 100%
5+10=25

what is the first six terms of the sequence f(n)=(-3)^n
Answer:
The first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:
[tex]-3, 9, -27, 81, -243, 729[/tex]
Step-by-step explanation:
Given the sequence
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
Here [tex]n[/tex] represents any term number in the sequence
Determining the first term
substitute n = 1 in the sequence to determine the first term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]\:f\left(1\right)=\left(-3\right)^1[/tex]
[tex]f\left(1\right)=-3[/tex]
Thus, the first term is -3.
Determining the 2nd term
substitute n = 2 in the sequence to determine the 2nd term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]\:f\left(2\right)=\left(-3\right)^2[/tex]
[tex]\:f\left(2\right)=9[/tex]
Thus, the 2nd term is 9.
Determining the 3rd term
substitute n = 3 in the sequence to determine the 3rd term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(3\right)=\left(-3\right)^3[/tex]
[tex]f\left(3\right)=-27[/tex]
Thus, the 3rd term is -27.
Determining the 4th term
substitute n = 4 in the sequence to determine the 4th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(4\right)=\left(-3\right)^4[/tex]
[tex]f\left(4\right)=81[/tex]
Thus, the 4th term is 81.
Determining the 5th term
substitute n = 5 in the sequence to determine the 5th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(5\right)=\left(-3\right)^5[/tex]
[tex]f\left(5\right)=-243[/tex]
Thus, the 5th term is -243.
Determining the 6th term
substitute n = 6 in the sequence to determine the 6th term
[tex]f\left(n\right)=\left(-3\right)^n[/tex]
[tex]f\left(6\right)=\left(-3\right)^6[/tex]
[tex]f\left(6\right)=729[/tex]
Thus, the 6th term is 729
Therefore, the first six terms of the sequence [tex]f\left(n\right)=\left(-3\right)^n[/tex] are:
[tex]-3, 9, -27, 81, -243, 729[/tex]

Answer:
a = 84°
b = 36°
c = 24°
d = 84°
e = 132°
Step-by-step explanation:
The parameters of the workers in the office are;
The number of staffs in the office = 60 staffs
The take-aways are pizza, curry, fish & chips, kebab and other
The frequency for the above take-aways = 14, 6, 4, 14, and 22 respectively
The variables for the angles representing the above take-aways on the pie chart = 'a', 'b', 'c', 'd', and 'e'; respectively
In order to find the size of the angles that represent each group of workers in the pie chart, we find the ratio of the group size to the total number of workers and we multiply the result by 360° as follows;
∠a = 360° × 14/60 = 84°
∠b = 360° × 6/60 = 36°
∠c = 360° × 4/60 = 24°
∠d = 360° × 14/60 = 84°
∠e = 360° × 22/60 = 132°
Solve for θ, round to the nearest tenths place.

Please help me. .....
Answer:
24 pounds
Step-by-step explanation:
Step 1: Find out how many pens he bought
12 pens per pack
Charles bought 60 packs
60 packs x 12 pens = 720 pens
Step 2: Find out how much Charles spent
2.80 per pack
Charles bought 60 packs
60 x 2.80 = 168 pounds
Step 3: Find out how many pens Charles sold
Charles sold 2/3 of his pens
2/3 x 720 = 480
Step 4: Find out how manypens he sold
Charles sold the pens for 40p
40p x 480 = 19200p
Step 5: Convert pences to pounds
19200p = 192 pounds
Step 6: Find the profit
192 - 168 = 24 pounds
Step 7: Therefore statement
Therefore he mad 24 pounds of profit

A smartphone has a screen that has a width of x and a height that is 1.8 times the width. The outer dimensions of the phone are shown.
Write an expression for the portion of the phone that is not occupied by the screen. Assume that the phone is rectangular.
Answer: 4.8x+3
Step-by-step explanation:
The portion of the phone that is not occupied by the screen is 4.9x + 3 cm².
What is Surface Area?For each three-dimensional geometrical shape, surface area and volume are determined. The area or region that an object's surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including sphere, cube, cuboid, cone, cylinder, etc. Each form has its own volume and surface area. Nevertheless, we can only estimate the area that two-dimensional figures like a square, circle, rectangle, triangle, etc. cover; there is no volume available.
As per the given data:
The width of the screen = x cm
Height of the screen = 1.9 times the width = 1.9x
Dimensions of the phone are given in the diagram.
The area of the screen = height × width
= 1.9x × x = 1.9x² cm²
The area of the phone = (1.9x + 3)(x + 1)
= 1.9x² + 1.9x + 3x + 3
= 1.9x² + 4.9x + 3 cm²
Area of the phone not occupied by screen:
= area of the phone - area of the screen
= 1.9x² + 4.9x + 3 - 1.9x²
= 4.9x + 3 cm²
Hence, the portion of the phone that is not occupied by the screen is 4.9x + 3 cm².

A swimming pool had 30 gallons of water in it. Then water was added to the pool at a rate of 5 gallons per second. The function y= 5t + 30 describes the relationship between the number of gallons, y, and the number of seconds water was added, t. Select all of the ordered pairs that correspond to input-output pairs for the function.
A. (45,3)
B. (3,45)
C. (0,30)
D. (30,0)
The (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.
What is function?Each element of X receives exactly one element of Y when a function from one set to the other is used. The sets X and Y are collectively referred to as the function's domain and co-domain, respectively.
Given the function:
y = 5t +30,
Here y is the no of gallons and t is the time.
Take the values of option A and substitute in the function,
45 = 5 × 3 +30
45 = 45
Hence, it is the correct-ordered pair,
Similarly, take option b
3 = 45 × 5 +30
3 ≠ 255
Now take option c,
0 = 30 × 5 +30
0 ≠ 180
Take the last option,
30 = 0 × 5 +30
30 = 30
Hence, it is also the ordered pair.
Therefore, the (45,3) and (30,0) are the correct-ordered pairs that correspond to input-output pairs for the function.

The act of factoring is to reduce numbers down to their____.
The act of factoring is to reduce numbers down to their prime number.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
A prime number is a positive integer having exactly two factors that are 1 and the number itself. Any number that does not follow this is termed a composite number.
For example:
Let the number 2310, then the factor of the number 2310 will be
2310 = 2 × 3 × 5 × 7 × 11
Where, 2, 3, 5, 7, and 11 are the prime numbers.

what was the original weight of the ball ?
Answer:
16.5
Step-by-step explanation:
A is the correct answer
Step-by-step explanation:
If you plug y=x+10 in for the Y variable you just have to solve by multiplying.
1.) It should look like this:
2x + 3(x +10) = 40
2.) You will distribute the three which will make the equation look like this:
2x + 3x + 30 = 40
3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.
but 16.5 is the answer

It's gonna be an irrational number because the length of the hypotenuse is 6.40312....... cm
[tex] {4}^{2} + {5}^{2} = {41}^{2} [/tex]
[tex] \sqrt{41} = 6.403124237[/tex]
An irrational number cannot be written as a simple fraction and the decimals would keep on going without a pattern (if it was repeating, it would be rational).
Answer:
If the legs are equal to 4 cm and 5 cm, respectively we can rewrite the equation 42+52=c2 -> 16+25=41=c^2 so then, c= the square root of 41, which is an irrational number.
