Answer: The required rate = 0.64 per pounce.
Step-by-step explanation:
We are given that,
Postal service charge = $10.30 per pound.
As we know, 1 pound = 16 ounces.
So, Postal service charge = $10.30 per 16 ounces.
Postal service charge[tex]=\$\dfrac{10.30}{16}\ \text{ per ounce}[/tex]
[tex]\approx 0.64\text{ per ounce}[/tex]
Hence, the required rate = 0.64 per pounce.
A utility pole is 24 feet tall and its shadow is 45 feet long. A nearby water tower is 32 feet tall. How long is the water tower's shadow?
Answer: The tower's shadow is 60 feet long.
Step-by-step explanation:
We can use a ratio to solve this:
24/45 = 32/x
Cross multiply: (Numerator of left side times the denominator of right side, and denominator of the left side by numerator of right side.)
24x = 32(45)
24x = 1440 divide both sides by 24
x = 60

owen and needed to get his computer fixed he took it to the repair store the technician at the store worked on the computer for 5.5 hours and charged him $70 for parts the total is $702.50 what was the total cost of labor per hour
To figure out this problem, let's set up an equation first to make it easier:
702.50 = 5.5x + 70
x = amount charged per hour
702.50 = 5.5x + 70
-70 -70
-----------------------------
632.5 = 5.5x

1. Write a system of equations to describe the situation. Then solve the system. Be sure to define your variables! Rizzo has $1.50 less in his piggy bank than his sister Shonda. If Shonda had $9 more, she would have three times as much money as Rizzo. How much money do each of the children have in their banks?
Answer:
The amount Rizzo has = x = $5.25
The amount Shonda has = y = $6.75
Step-by-step explanation:
Let us represent:
The amount Rizzo has = x
The amount Shonda has = y
Rizzo has $1.50 less in his piggy bank than his sister Shonda.
x = y - 1.50.......Equation 1
If Shonda had $9 more, she would have three times as much money as Rizzo.
y + 9 = 3(x)
y + 9 = 3x..... Equation 2
y = 3x - 9
We substitute 3x - 9 for y in Equation 1
x = y - 1.50.......Equation 1
x = 3x - 9 - 1.50
9 + 1.50 = 3x - x
10.50 = 2x
x = 10.50/2
x = $5.25
Solving for y
y = 3x - 9
y = 3(5.25) - 9
y = $6.75
Therefore:
The amount Rizzo has = x = $5.25
The amount Shonda has = y = $6.75

ill give a brainest no cap plz actually help
Step-by-step explanation:
Amount borrowed=400
interest rate=4%
Amount of interest after x years =0.04XxX400=$16x
Total to be paid back=400+0.04XxX400=400+16(1)
1) the amount of interest.if Franco pays back the loan in x=1 years is
16x1=$16
2) the amount of interest,if Franco pay back the loan in x=2 years is,
16x2=$32
3) the amount of franco will pay the lender after 2 years will be
400+(16x2)=400+32=$432

Here are the first four terms of a quadratic sequence.
The nth term of this sequence is an² + bn + c.
1, 11, 27 and 49
Find the values of a, b and c.
Answer:
a = 3, b = 1, c = - 3
Step-by-step explanation:
Substitute n = 1, 2, 3 into the n th term
a + b + c = 1 → (1)
4a + 2b + c = 11 → (2)
9a + 3b + c = 27 → (3)
Subtract (1) from (2) term by term to eliminate c
Subtract (2) from (3) term by term to eliminate c
3a + b = 10 → (4)
5a + b = 16 → (5)
Subtract (4) from (5) term by term to eliminate b
2a = 6 ( divide both sides by 2 )
a = 3
Substitute a = 3 into (4) and evaluate for b
3(3) + b = 10
9 + b = 10 ( subtract 9 from both sides )
b = 1
Substitute a = 3, b = 1 into (1) and evaluate for c
3 + 1 + c = 1
4 + c = 1 ( subtract 4 from both sides )
c = - 3
Then a = 3, b = 1 and c = - 3
The measure of a, b and c is 3, 1 and - 3 respectively.
What is a quadratic sequence?A quadratic sequence is a sequence whose nth term is given by the general formula -
A{n} = an² + bn + c.
Given are the 4 terms of the quadratic sequence as 1, 11, 27 and 49.
Now, we can the following equations as -
A{1} = a + b + c = 1
a + b + c = 1
c = 1 - a - b ........ Eq[1]
A{2} = 4a + 2b + c = 11
4a + 2b + c = 11
c = 11 - 4a - 2b ........ Eq[2]
A{3} = 9a + 3b + c = 27
9a + 3b + c = 27
c = 27 - 9a - 3b ........ Eq[3]
A{4} = 16a + 4b + c = 49
16a + 4b + c = 49
c = 49 - 16a - 4b ........ Eq[4]
Equate Eq[1] and Eq[2] -
1 - a - b = 11 - 4a - 2b
1 - 11 = - 4a - 2b + a + b
- 10 = - 3a - b
3a + b = 10 ........... Eq[5]
Equate Eq[3] and Eq[4] -
27 - 9a - 3b = 49 - 16a - 4b
- 9a - 3b + 16a + 4b = 49 - 27
7a + b = 22 .......... Eq[6]
We can write -
7a + 10 - 3a = 22
4a + 10 = 22
4a = 12
a = 3
and
b = 10 - 3a
b = 10 - 9
b = 1
At last -
c = 1 - a - b
c = 1 - 3 - 1
c = - 3
Therefore, the measure of a, b and c is 3, 1 and - 3 respectively.

If a circle is cut from a square piece of plywood, as shown in the picture below, how much plywood would be leftover?
Answer:
What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.
Step-by-step explanation:
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 ()
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.

-7(x+5) =21
apply the distributive property and simplify
Answer:
x=−8
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(x+5)=21
(−7)(x)+(−7)(5)=21(Distribute)
−7x+−35=21
−7x−35=21
Step 2: Add 35 to both sides.
−7x−35+35=21+35
−7x=56
Step 3: Divide both sides by -7.
−7x/−7 = 56/−7
x=−8
Answer:-
Distributed: -7x+(-35)=21 Simplified: x=-8
Step-by-step explanation:-
Distributed:

4. 13x + 5y = -11
13x + 11y = 7
Solution:
Answer:
y=2/3
Step-by-step explanation:
Answer:
(-2,3) x= -2 y=3
Step-by-step explanation:
The first thing you should do is convert both into standard y=mx+b form
For the first equation you subtract 5y and add 11 to both sides to get
13x+11= -5y
you divide by negative 5 to get
-13x/5-11/5=y
For the second equation we subtract 11y and 7 from both sides to get
13x-7= -11y
divide both sides by -11 to get
-13x/11 + 7/11
We then set both equations equal to each other and solve for x
-13x/5-11/5= -13x/11 + 7/11
Add 11/5 to both sides to get
-13x/5 = -13x/11 + 156/55
Add 13x/11 to both sides to get
-78/55x=156/55
Divide and solve for x to get -2
Then plug x = -2 into the original equations to find y
13*-2 + 5y = -11
-26 + 5y = -11
Add 26 to both sides
5y= 15
y =3
