The mean of three numbers is 10. The mean of other four numbers is 12. Find the mean of all the numbers.
Answers
Answer:
11.14
Step-by-step explanation:
Mean = sum of numbers / total numbers
the mean of the 7 numbers = sum of the numbers / 7
sum of numbers for the 3 numbers = 10 x 3 = 30
Sum of numbers for the other 4 numbers = 12 x 4 = 48
Sum of the 7 numbers = 48 + 30 = 78
Mean of the 7 numbers = 78 / 7 = 11.14

D) soda: $0.50 pretzels: $0.50
Answers
Answer:
B) soda: $0.80 pretzels: $1.20
Step-by-step explanation:
system of equations:
3s+2p=4.80
1s+1p=2.00
solve:
-2(1s+1p=2.00) = -2s-2p=-4.00
3s+2p=4.80
-2s-2p=-4.00
1s=0.80
3(0.80)+2p=4.80
2.40+2p=4.80
2p=2.40
p=1.20

Using the function g(x) = -2x + 5, what would the input need to be for an output of -5? a.5 b.0 c.15 d.-5
Answers
Answer:
A
Step-by-step explanation:
We are given the function g(x) = -2x +5
If we need an output of -5, then:
-5 = -2x + 5
-10 = -2x
x = 5
A
Answer:
a. 5
Step-by-step explanation:
We can solve this by simply guessing and checking; plugging in each answer until we get -5.
a) -2(5) + 5
-10 + 5
-5
We can also set the function equal to -5 and solve for x.
-2x + 5 = -5
-2x = -10
x = 5

A scale drawing of a rectangular park is 5 inches wide and 7 inches ong. The actal prake is 280 yards long. What is the area of the actual park, in square yards?
Answers
Given:
A scale drawing of a rectangular park is 5 inches wide and 7 inches long.
The actual park is 280 yards long.
To find:
The area of the actual park.
Solution:
Length of drawing = 7 inches
Length of actual park = 280 yards
The scale factor is
7 inches : 280 yards
1 inches : 40 yards
The width of the drawing is 5 inches. So, the width of actual part is
[tex]40\times 5=200 yards[/tex]
The area of the actual park is
[tex]Area=Length \times width[/tex]
[tex]Area=280\times 200[/tex]
[tex]Area=56000[/tex]
Therefore, the area of the actual park is 56000 sq. yards.

Solve for all values of x by factoring.
x^2-20x+72=-3x
Answers
Answer:
x = 9, 8
Step-by-step explanation:
1) To find all values of x by factoring, move all the terms to one side, setting them to zero. So, add both sides by -3x to move the term:
[tex]x^2-20x + 72 = -3x\\x^2 -17x+72 = 0[/tex]
2) Now, factor the expression. The product of -8 and -9 equals 72, and adding the two numbers together equals -17. So, the factored expression must be (x-9) (x-8):
[tex]x^2-17x + 72 = 0 \\(x-9)(x-8)= 0[/tex]
3) Look at the expressions in the parentheses. Whatever values of x that makes each expression equal 0 will be the answer. Thus, x must equal 9 and 8.

S(t) = -16t^2+96t+256 the quadratic function models the balls height above the ground, s(t), in feet, t seconds after it was thrown when a person standing close to the edge on top of a 248-foot building throws a baseball ball vertically upward. When will the ball reach its maximum height, and what is the maximum height of the ball?
Answers
Answer:
The ball reaches maximum height in 3 seconds.
The maximum height of the ball is of 400 feet.
Step-by-step explanation:
Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, f(x_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]f(x_{v})[/tex]
In this question:
The height is modeled by:
[tex]s(t) = -16t^2 + 96t + 256[/tex]
So, the coefficients are:
[tex]a = -16, b = 96, c = 256[/tex]
Instant of time the ball reaches maximum height:
[tex]t_{v} = -\frac{96}{2(-16)} = -\frac{96}{-32} = 3[/tex]
The ball reaches maximum height in 3 seconds.
What is the maximum height of the ball?
This is s(3).
[tex]s(3) = -16t^2 + 96t + 256 = -16*3^2 + 96*3 + 256 = 400[/tex]
The maximum height of the ball is of 400 feet.
The legs of a right triangle measure 10 m and 24 m. What is the length of
the third side of the right triangle?
Answers
Answer:
26
Step-by-step explanation:
100 +(24^2) = 676
square root of 676 = 26
Answer:
either 26 m or 21.8174 m
Step-by-step explanation:
If 24 is the hypotenuse, then 24^2-10^2=x^2
x^2=576-100=476
x=21.8174 m
if x=hypotenuse, then 24^2+10^2=x^2
x^2=576+100=676
x=26 m

Bank A is lending money at 6.4% interest compounded annually. The rate at Bank B is 6.3% compounded monthly, and the rate at Bank C is 6.35% compounded daily. Determine the amount of interest you would earn at each bank if you invest $1500 for 12 months.Which bank will you pay the least amount?
Answers
Answer:
$1596
$1597.28
$1598.33
bank A
Step-by-step explanation:
The formula for calculating compound interest:
FV = P (1 + r/m)^mn
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
Bank A = $1500(1.064) = $1596
Bank B = $1500( 1 + 0.063/12)^12 = 1597.28
Bank C = $1500( 1 + 0.0635/365)^365 = $1598.33
Bank A pays the least amount of interest
