Problem:
On a trip to the lake, Kerrie and Shelly rode their bicycles four more than three times as many miles in the afternoon as they rode in the morning. If the entire trip is 112 miles, how far did they ride in the morning and how far in the afternoon?
Please SHOW ALL OF YOUR WORK!
Answer:
The answer is 27 miles in the morning and 85 miles in the afternoon.
Step-by-step explanation:
So first you have to set up an equation.
X represents: the number of miles they rode in the morning.
3X + 4 represents: 4 more than 3 times this many in the afternoon
3X+4 + X = 112 represents: adding the morning miles and the afternoon miles together to get the total trip of 112 miles
Your equation to solve 3X+4+X =112
Now you can solve the equation
3X+4+X =112
Combine like terms (x's)
3X + X = 4X
4X+4=112
Subtract 4 from each side:
4X+ 4 - 4= 112-4
4-4 = 0 and 112-4 = 108
4X = 108
Divide both sides by 4
4X/4 = 108/4
4/4 = 1X and 104/4 = 27
X = 27
Remember X represents the number of miles they rode in the morning, so they rode 27 miles in the morning.
Remember 3X+4 represents the number of miles they rode in the afternoon.
3X+4 =
3(27)+4 =
81+4 =
85 miles.
That means in the afternoon, they rode 85 Miles

A culture of 1.75×1018 bacteria is in petri dish A. A culture of 6.25×1015 bacteria is in petri dish B. How many times greater is the number of bacteria in petri dish A than petri dish B
Petri dish A has 280 times more bacteria than petri dish B.
To determine how many times greater the number of bacteria in petri dish A is compared to petri dish B, we use division.
The number of bacteria in petri dish A is [tex]1.75*10^{18[/tex].The number of bacteria in petri dish B is [tex]6.25*10^{15.[/tex]We divide the number of bacteria in dish A by the number of bacteria in dish B: [tex](1.75*10^{18}) / (6.25*10^{15})[/tex].Since division of exponents with the same base involves subtracting the exponents, we have: [tex]1.75 / 6.25 * 10^{(18-15)} = 0.28 * {10^3.[/tex]Converting 0.28 into a coefficient with a single digit gives us [tex]2.8 * 10^2.[/tex]Thus, the number of bacteria in petri dish A is 280 times greater than in petri dish B.Can someone help me with this?
A nutrition label indicates that one serving of Apple crisp oatmeal has 2.5 grams of fat. How many grams of fat are there in 3.75 servings? Justify your answer
To find the total grams of fat in 3.75 servings of Apple crisp oatmeal, multiply the fat per serving (2.5 grams) by the number of servings, resulting in 9.375 grams of fat.
To calculate the number of grams of fat in 3.75 servings of Apple crisp oatmeal, we can multiply the amount of fat in one serving by the number of servings. Given that one serving contains 2.5 grams of fat, we would perform the following calculation:
2.5 grams of fat/serving times 3.75 servings = 9.375 grams of fat
Therefore, there are 9.375 grams of fat in 3.75 servings of Apple crisp oatmeal. The nutrition label helps us understand the nutritional content of food, like the breakdown of macronutrients such as fats, carbohydrates, and proteins, as well as the caloric content of these macronutrients.

How many 5/9’s are in 1?
There are 1 whole 5/9 and 4/5 from 5/9 or 1.8 or 9/5 lots in 1
To determine how many 5/9s are in 1, we can follow these steps:
Write down the equation:
[tex]x*\frac{5}{9} = 1[/tex]
Solve for x. Multiply both sides of the equation by the reciprocal of 5/9, which is 9/5, we get
[tex]x \cdot \frac{5}{9} \cdot \frac{9}{5} = 1 \cdot \frac{9}{5}[/tex]
[tex]x = \frac{9}{5}[/tex]
Express 9/5 as a mixed number:
Divide 9 by 5: [tex]9 \div 5 = 1[/tex] with a remainder of 4
Therefore, [tex]\frac{9}{5} = 1 \frac{4}{5}[/tex]
So, there is 1 whole 5/9 and 4/5 from 5/9 or 1.8 or 9/5 lots in 1

Simplify (−34.67)0
Final answer:
Any non-zero number raised to the power of zero is equal to 1, so [tex](-34.67)^0[/tex] simplifies to 1.
Explanation:
The question asks us to simplify [tex](-34.67)^0[/tex]. In mathematics, any non-zero number raised to the power of zero is equal to 1. This rule is known as the zero exponent rule and is an important concept in algebra.
Applying this rule to the given expression, regardless of the value of −(34.67), the whole expression to the power of zero will simply be:
[tex](-34.67)^0[/tex] = 1
From a more abstract perspective, raising a number to the power of 0 can be seen as a special case of exponentiation that preserves the multiplicative identity. In other words, it serves as the identity element for multiplication in the set of non-zero real numbers. This property is consistent with the general pattern observed in exponentiation, where raising a number to different powers yields specific results based on mathematical principles and definitions.

A plumber has a 50 foot piece of PVC pipe. how many 9/5 foot pieces can be cut from the 50 foot piece?
Answer:
[tex]27\frac{7}{9}\approx 27[/tex] pipes.
Step-by-step explanation:
We have been given that a plumber has a 50 foot piece of PVC pipe. We are asked to find the number of 9/5 foot pieces of pipes that could be cut from the 50 foot piece.
To find the number of 9/5 foot pieces of pipes, we will divide total length of PVC pipe by 9/5 foot.
[tex]\text{Number of 9/5 foot pieces of pipes}=50\div \frac{9}{5}[/tex]
Convert to multiplication problem:
[tex]\text{Number of 9/5 foot pieces of pipes}=50\times \frac{5}{9}[/tex]
[tex]\text{Number of 9/5 foot pieces of pipes}=\frac{250}{9}[/tex]
[tex]\text{Number of 9/5 foot pieces of pipes}=27\frac{7}{9}[/tex]
[tex]\text{Number of 9/5 foot pieces of pipes}\approx 27[/tex]
Therefore, the plumber can make [tex]27\frac{7}{9}\approx 27[/tex] pipes.
28 of the [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.
Given the following data;
Total length of PVC pipe = 50 footRequired length of PVC pipe = [tex]\frac{9}{5}[/tex] footIn this exercise, you're required how many [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece. To do this we would divide the 50 foot piece of PVC pipe by [tex]\frac{9}{5}[/tex].
[tex]50[/tex] ÷ [tex]\frac{9}{5}[/tex] = [tex]\frac{50}{\frac{9}{5}}[/tex]
Simplifying the equation, we have;
[tex]\frac{50 \;X \;5}{9}[/tex]
[tex]\frac{250}{9}[/tex]
Number of pipes = 27.77 ≈ 28 pipes.
Therefore, 28 of the [tex]\frac{9}{5}[/tex] foot pieces can be cut from the 50 foot piece.
