Add - 4.7 and 2.4
\( \sf \: - 4.7 + 2.4 \\ = \boxed{\sf \: - 2.3}\)
Remember -> when you add a positive number & a negative number you must subtract them & then put the sign (+ or -) according to the greater number in terms of number value.

Suppose a certain breed of dog loses about 75 hairs per day. What integer represent this change in the amount of hair per week write a mathematical argument that can be used to defend your solution
Answer:
75 hairs/ day = 525 hairs / week
Step-by-step explanation:
so your base question for this is 75 hairs/ day =? h/ week. how? if the dog is losing 75 hairs per day, then you would do 75 x 7 becuase there are 7 days in a week. the answer to that would give you how many hairs the dog was losing per week. (see attached image for reference)

Answer:
D. 6/15
Step-by-step explanation:
You divide 6 (the number of times landed on a specific place) by 15 (the number of times spun). When you solve for 6/15, the answer is .4. In the form as a percentage, it would be 40%.

The price was $250. Now its 100 find the percentage change
Answer:
Step-by-step explanation:
The formula for percent change is
\(\frac{original-new}{original}*100\)
Therefore,
\(\frac{250-100}{250}*100=60\)%
Answer: 60%
Step-by-step explanation:250 - 100 = 150
150/250 = 60/100 = 60%

Answer: 10.32
Step-by-step explanation:
First, we write down the question.
-3.28 -(-4.4) + (-p)
Next, we substitute p = 9.7
-3.28 -(-4.4) + (-9.7)
Finally, we solve the integers and solve.

WILL GIVE BRAINLIEST! PLEASE HURRY!!Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples’ ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.
Look at the attachment.
Determine how many texts a 16 year old would send based on the trend line equation for both Keiko and Eric. Round to the nearest whole number.
Keiko = 76, Eric = 100
Keiko = 66, Eric = 64
Keiko = 70, Eric = 46
Keiko = 96, Eric = 100
Answer:
Step-by-step explanation:
For Keiko's trend line equation, we have t = 0.95a + 59. Plugging in a = 16, we get t = 0.95(16) + 59 = 74.2. Rounding to the nearest whole number, we get t ≈ 74.
For Eric's trend line equation, we have t = 0.55a + 90. Plugging in a = 16, we get t = 0.55(16) + 90 = 98.8. Rounding to the nearest whole number, we get t ≈ 99.
Therefore, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation. So, the answer is Keiko = 74, Eric = 99.
The solution is, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.
here, we have,
For Keiko's trend line equation,
we have t = 0.95a + 59.
Plugging in a = 16,
we get t = 0.95(16) + 59 = 74.2.
Rounding to the nearest whole number, we get t ≈ 74.
and, we have,
For Eric's trend line equation,
we have t = 0.55a + 90.
Plugging in a = 16,
we get t = 0.55(16) + 90 = 98.8.
Rounding to the nearest whole number, we get t ≈ 99.
Therefore, a 16 year old would send approximately 74 texts per day based on Keiko's trend line equation and approximately 99 texts per day based on Eric's trend line equation.
So, the answer is Keiko = 74, Eric = 99.

In a classroom of 33 students, the ratio of boys to girls is 3 : 8.
How many boys are in the class?
Answer:
the answer is 9 :)
Step-by-step explanation:
Answer: 9
Step-by-step explanation:
In a classroom of 33 students, the ratio of boys to girls is 3 : 8. With the ratio you can add both gender and get 11 divide 33 by 11 which is 3 so multiply both 3 and 8 by 3 which makes a ratio of. 9:24
Given f(x)=2^x and g(x)= f(x-3)+4, write the new function rule (equation) for function g and describe (using words) the two transformations that occur between the function f and the function g
*Some good words to consider using would include horizontal, vertical, stretch, compression,
translation, reflection, and phrases such as “to the left”, “to the right”, “up”, “down”, “by a
factor of__, or ”over the __ axis”.
Answer:
Just like Transformations in Geometry, we can move and resize the graphs of functions. Let us start with a function, in this case it is f(x) = x2, but it could be anything: ... g(x) = x2 + C. Note: to move the ... If you change that to (age+4) = 25 then you will get it when you are 21. Adding 4 ... Example: the function v(x) = x3 - x2 + 4x.
Step-by-step explanation:
The graph of the function y = 2x⁴ - 5x³ + x² - 2x + 4 is plotted and attached.
What is a polynomial?Polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s). For example -
y = 4x⁴ + 3x³ + 2x² + 6x + 7
We have the following polynomial functions -
f(x) = 2ˣ
g(x) = f(x - 3) + 4
We can write g(x) as -
g(x) = 2ˣ ⁻ ³ + 4 = (2ˣ/2³) + 4
g(x) = (2ˣ/8) + 4
The graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards.
Therefore, the graph of f(x) is stretched by the factor of 1/8 and is shifted 4 units upwards to given the function g(x)
