Type your answer in decimal form. Do not round.
230 ounces = ______ cups
The answer in decimal form is 230 ounces = 28.75 cups
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
1 ounce = 0.125 cup
Multiply 230 on both sides.
230 ounces = 230 x 0.125 cups
230 ounces = 28.75 cups
Thus,
23o ounces is equal to 28.75 cups.

The points (4,18) and (14,63) form a proportional relationship. Find the slope of the line through the
points. Then use the slope to graph the line.
The slope is
Answer:
The slope is 4.5
Step-by-step explanation:
Here, we want to find the slope of the line that passes through the given points
Mathematically, we use the slope formula here
Using the slope formula m, we have the equation as follows;
m = (y2-y1)/(x1-x1)
m = (63-18)/(14-4) = 45/10 = 4.5

convert the body temperature of 36.4°C to °F?
Answer:
97.52
Step-by-step explanation:
First, we need to know the formula to convert Celsius into Fahrenheit.
Given, [tex]F= \frac{9}{5} C +32[/tex], let us plug in what we know, 36.4 C, into the equation!
[tex]F=\frac{9}{5} * 36.4 +32\\F= 65.52 +32\\F= 97.52[/tex]
Therefore, a body temperature of 36.4 C would be 97.52 Fahrenheit!
I hope this helps! Please let me know if you have any further questions :)
The value of temperature will be 97.52° F.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The value of temperature = 36.4° C
Now,
We know that;
The relation between the degree and Fahrenheit is,
⇒ F = 9/5 C + 32
⇒ F = 9/5 × 36.4 + 32
⇒ F = 65.52 + 32
⇒ F = 97.52
Thus, The value of temperature = 36.4° F

how do I make fractions into mixed numbers??? like 3 8/4
Answer:
look down
Step-by-step explanation:
OK so u take something like 9/3 and then ask how many times the 3 goes into the 9 and that is your whole number. whatever is left is your top of the fraction and the bottom stays the same hope this helped
Answer:
To make an improper fraction into a mixed fraction:
1. Divide the numerator by the denominator
2. Write down the whole number answer
3. Then write down any remainder above the denominator
Example:
Turn 8/3 into a mixed fraction.
8 ÷ 3 = 2 R2
So... 2[tex]\frac{2}{3}[/tex]
To make a mixed fraction into an improper fraction:
1. Multiply the whole number part by the fraction's denominator.
2. Add that to the numerator.
3. Then write the result on top of the denominator.
Example:
Turn 4[tex]\frac{6}{7}[/tex] into an improper fraction.
4 x 7 = 28
28 + 6 = 34
So... [tex]\frac{34}{7}[/tex]

To find simple interest, you multiply the principal (in dollars), the interest rate (as a decimal), and the time in years. The equation 24 = 400 0.015 4 shows how to find the simple interest for a certain account after 4 years. What is the interest rate (as a percent)? How much is the simple interest? What is the principal?
Answer:
1.5%
$24
$400
Step-by-step explanation:
the equation to find simple interest is
i = p×r×t
i stands for the interest
p stands for the principal
r stands for the rate of interest
t stands for the time in years
in this problem, the equation has already been replaced by numbers
so the i was replaced by the amount of simple interest (24) so thats the answer to the 2nd question
the r was replaced by the rate of interest as a decimal (0.015), and to change that decimal into a percent for the 1st question, just move the decimal point 2 spaces to the right, so in this case it would be 1.5%
and the p was replaced by the principal (400) so thats the answer to the 3rd question

Four years ago, Ana's age was double Rodricks age. In four years, they will both
add up to 56 years old. What ages are they right now?
Answer:
Rod is 17-1/3 and Ana is 30-2/3
Step-by-step explanation:
let x = Rod's age now
then Rod's age 4 years ago was x - 4 and Ana's age then was 2(x-4)
therefore Ana's age now is 2(x - 4) + 4 = 2x - 8 + 4 = 2x - 4
In four years Rod will be x + 4 and Ana will be 2x - 4 + 4 = 2x
Now x + 4 + 2x = 56
3x + 4 = 56
3x = 52
x = 17-1/3 = Rod's age
2x - 4 = 2(14) - 4 = 26-2/3 = Ana's age
Check: in 4 years Rod will be 21-1/3 and Ana will be 34-2/3
21-1/3 +34-2/3 = 56

9514 1404 393
Answer:
A
Step-by-step explanation:
The unit rate in scenario A is 7, not 6, so it is inappropriate to use the equation 6x -7 = 29 for that scenario.
Situation A cannot be properly represented by the given equation.

Answer: The independent variable is the days, and the dependent is the amount of sales.
Step-by-step explanation:
The days are independent because there is no way to change it, and it will always be. (like a schedule depends on time)
The sales are dependent because they rely on the days, especially because you can't sell things without there being time.
