Answer:
1400 if not compounded
Step-by-step explanation:
12500x.03
Answer:
14,000
Step-by-step explanation:
Step 1:
- 12,500x0.03=375
- 375x4=1500
1500 is the interest amount
but it's asking for the total so
Step 2:
- 12500+1500=14,000

7. The island is rich with hot chili peppers. You can collect 1.6 pecks a day. How many liters could you collect in 1 week?
The required liters of hot chili papers collected in a week is 98.56 liters.
What is a unit of measurement?Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.
1 peck = 8.8 liters
1.6 peck = 8.8 × 1.6 liters
1.6 pecks = 14.08 liters
So, in 1-week liter that could be collected is given as,
⇒ 14.08 × 7 [1 week = 7 days]
⇒ 98.56 liters
Thus, the required liters of hot chili papers collected in a week is 98.56 liters.

Solve the equation for W
Answer:
fourth option
Step-by-step explanation:
Given
[tex]\frac{2x-1}{y}[/tex] = [tex]\frac{w+2}{2z}[/tex] ( cross- multiply )
y(w + 2) = 2z(2x - 1) = 4xz - 2z ( divide both sides by y )
w + 2 = [tex]\frac{4xz-2z}{y}[/tex] ( subtract 2 from both sides )
w = [tex]\frac{4xz-2z}{y}[/tex] - 2

If 8b-9=b then 7b=?
Please answer if you can!
Also it’s NOT 1.5
Answer:
9 is your answer.
Step-by-step explanation:
Solve for b. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
First, add 9 to both sides:
8b - 9 (+9) = b (+9)
8b = b + 9
Next, subtract b from both sides:
8b (-b) = b (-b) + 9
8b - b = 9
7b = 9
Divide 7 from both sides:
(7b)/7 = (9)/7
b = 9/7
Plug in 9/7 for b in the equation given:
7(b) = 7(9/7) = 9
9 is your answer.

The mean of four numbers is 70. When a fifth number is included, the mean of the five numbers is 80. What is the fifth number?
=============================================
Explanation:
S = sum of the first four values
S/4 = 70 since we divide the sum by 4 to get the mean of the first four values
S = 280 is the result after multiplying both sides by 4
Let x be the fifth unknown value. Adding it onto S leads to S+x = 280+x. This represents the sum of all five values.
Dividing that sum 280+x over 5 leads to the new mean 80, which leads to...
----------
(280+x)/5 = 80
280+x = 5*80
x+280 = 400
x = 400-280
x = 120
The fifth number is 120
The fifth number is 120
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the four numbers be = a , b , c , d
Let the fifth number be = e
Now , the mean of 4 numbers is m = 70
So , the equation will be
( a + b + c + d ) / 4 = 70
Multiply by 4 on both sides , we get
a + b + c + d = 280 be equation (1)
Now , the mean of 5 numbers is m = 80
So , the equation will be
( a + b + c + d + e ) / 5 = 80
Multiply by 5 , we get
a + b + c + d + e = 400 be equation (2)
Substitute the value of equation (1) in equation (2) , we get
a + b + c + d + e = 400
280 + e = 400
Subtracting 280 on both sides , we get
e = 400 - 280
e = 120
Therefore , the value of e is 120
Hence , The fifth number is 120

18x + 3y = -21 slope intercept form
Answer: y=-6x-7
Step-by-step explanation:
Slope-intercept form is y=mx+b. This means, we want to isolate y.
18x+3y=-21 [subtract both sides by 18x]
3y=-18x-21 [divide both sides by 3]
y=-6x-7
Now, our equation is in slope-intercept form.

What are the roots of the equation 4x^2 + 16x + 25 = 0 in simplest a + bi form?
Answer:-2 + 3i/2, and -2-3i/2
Step-by-step explanation:
Apply the quadratic formula.
We have (-16 +-sqrt(16^2-4*4*25))/8.
Simplifying, we have (-16+-12i)/8.
Thus, the roots are -2 + 3i/2, and -2-3i/2
Answer:
The roots are
[tex]x = - 2 + \frac{3}{2} \: i \: \: \: \: or \: \: \: \: x = - 2 - \frac{3}{2} \: i \\ [/tex]Step-by-step explanation:
4x² + 16x + 25 = 0
Using the quadratic formula
That's
[tex]x = \frac{ - b\pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]From the question
a = 4 , b = 16 , c = 25
Substitute the values into the above formula and solve
We have
[tex]x = \frac{ - 16\pm \sqrt{ {16}^{2} - 4(4)(25)} }{2(4)} \\ x = \frac{ - 16\pm \sqrt{256 - 400} }{8} \\ x = \frac{ - 16\pm \sqrt{ - 144} }{8} \\ x = \frac{ - 16\pm12 \: i}{8} \\ [/tex]Separate the real and imaginary parts
That's
[tex]x = \frac{ - 16}{8} \pm \frac{12}{8} \: i \\ x = - 2\pm \frac{3}{2} i[/tex]We have the final answer as
[tex]x = - 2 + \frac{3}{2} \: i \: \: \: \: or \: \: \: \: x = - 2 - \frac{3}{2} \: i \\ [/tex]Hope this helps you
lX – 12.2l= 0.3 gives the minimum and maximum acceptable lengths of the wires in centimeters. What is the minimum acceptable length of a wire?
Work Shown:
|x-12.2| = 0.3
x-12.2 = -0.3 or x-12.2 = 0.3
x = -0.3+12.2 or x = 0.3+12.2
x = 11.9 or x = 12.5
The min length is 11.9 cm and the max length is 12.5 cm
Subtracting 12.2 from either x value leads to a positive difference of 0.3 which is the margin of error.

30. When asked his age, the algebra teacher said, "If you

result is 50. How old is be?
F. 23
G. 25
H. 27
J. 46
K. 50
Answer:
25 years old
Step-by-step explanation:
Let the teacher's age be a.
Then:
a^2 - 23a = 50
In standard form, this quadratic is
x^2 - 23a - 50 = 0
Factoring this, we get (x - 25)(x + 2) = 0
So a is either 25 or a is -2. Only a = 25 is relevant here.
