Answer:
44
Step-by-step explanation:
first we take the number he gave to his mom and put it to the side for later then we see that 8 bags had 4 candy bars each so 8*4 is 32 then we bring the 12 bars that he gave to his mom and add that to 32 so 32+12 and the answer would be 44
Ross bought a total of 44 candy bars, considering the 12 he gave to his mom and the 32 he divided among the 8 small bags.
To determine how many candy bars Ross bought at the store, we first need to calculate the total number of candy bars in the small bags. Ross divided the remaining candy bars into 8 small bags, with each small bag containing 4 candy bars. Therefore, the total number of candy bars in the small bags is
8 bags x 4 candy bars per bag,
which equals 32 candy bars. However, we must not forget that Ross also gave 12 candy bars to his mom. Thus, the total number of candy bars Ross bought is the sum of the candy bars given to his mom and the candy bars in the small bags, which is
12 candy bars + 32 candy bars,
resulting in 44 candy bars.

Find the sum.
Homework: 9.4 arithmetic series
Answer:
Step-by-step explanation:
a1 = 3(1) - 7 = - 4
a2 = 3(2) - 7 = -1
d = a2 - a1
d = -1 - (-4)
d = -1 + 4
d = 3
a60 = 3(60) - 7
a60 = 180 - 7
a60 = 173
n = 60
Sum = (a1 + a60) * n / 2
Sum = (-4 + 173) * 60/2
Sum = (169)*30
Sum = 5070
==================
Just to check, we'll use the second summation formula
d = 3
n = 60
a1 = -4
Sum = (2*a1 + (n - 1)*d )*n / 2
Sum = (2*(-4) + (60 -1)*3)* 60/2
Sum = (-8 + 59*3) * 30
Sum = (177 - 8)*30
Sum = 169 * 30
Sum = 5070

To simplify the expression, combine the exponents and evaluate the values to get the simplified expression 1/12.
Explanation:To simplify the expression, we can combine the exponents of the same base. Let's break it down step-by-step:
Combine the exponents of 4: (-3+2) = -1Combine the exponents of 3: (4-5) = -1Combine the exponents of 4: (2-2) = 0So, the simplified expression is 4-1 * 3-1 * 40. Any number raised to the power of 0 is equivalent to 1, so the expression can be further simplified to 4-1 * 3-1 * 1. Finally, we can evaluate the values: 4-1 = 1/4, and 3-1 = 1/3.
Therefore, the simplified expression is (1/4) * (1/3) = 1/12.

Step-by-step explanation:
Factor out x from each term
= x(x² + x - 6)
To factor the quadratic
Consider the factors of the constant term (- 6) which sum to give the coefficient of the x - term (+ 1)
The factors are + 3 and - 2, since
+ 3 × - 2 = - 6 and + 3 - 2 = + 1, hence

An animal shelter has a total of 275 animals composed of dogs and cats. The number of cats is 5 more than one half of the number of dogs. How many dogs are in the shelter?
Answer: There are 180 dogs in the shelter.
Step-by-step explanation:
Let be "c" the number of cats in the shelter and "d" the number of dogs in the shelter.
You know that the total number of dogs and cats in the animal shelter is 275. Then you can express this with:
[tex]d+c=275[/tex]
If the number of cats is 5 more than one half of the number of dogs, you can express it with:
[tex]c=\frac{d}{2}+5[/tex]
Then, substitute [tex]c=\frac{d}{2}+5[/tex] into [tex]d+c=275[/tex] and solve for "d" to calculate the number of dogs that are in the shelter. Then:
[tex]d+c=275\\\\d+\frac{d}{2}+5=275\\\\d+\frac{d}{2}=275-5\\\\\frac{2d+d}{2}=270\\\\\frac{3d}{2}=270\\\\3d=270*2\\\\d=\frac{540}{3}\\\\d=180[/tex]

Answer:
145°
Step-by-step explanation:
The angle is 90°+55°=145°
Answer: 145°
Step-by-step explanation:
The angle of straight lines is always 180°, so I took 180 and subtracted 55 from it, and then 90 to get 35. I got 90 because the x and y axis are perpendicular to each other, and the angle between perpendicular lines is always 90. 35° is the angle of the small un marked section to the left of the circles, so to get the angle of the circle-like line, I did 180-35 to get 145°.

Step-by-step explanation:
In translating graphs of functions, we can follow 2 rules:
1. The graph of [tex]f(x)+a[/tex] is the graph of [tex]f(x)[/tex] shifted a units UP VERTICALLY and the graph of [tex]f(x)-a[/tex] is the graph of [tex]f(x)[/tex] shifted a units DOWN VERTICALLY.

a. Find the interest earned.
$280
b. Find the balance of the account.
$
Answer:
$2280
Step-by-step explanation:
I see you've already found part a, which is to find the amount of interest earned. The next part is easy, to find the balance of the account after four years, just add the interest you've found back to the principal (the original size of the account or loan). $2000 + $280 equals $2280.
The interest earned on the account is $280. The balance of the account after 4 years is $2280.
Explanation:To find the interest earned on the account, we use the formula for simple interest:
I = PRT
where:
I is the interest P is the principal amount (the initial amount of money) R is the rate of interest T is the time in years
Substituting the given values:
I = $2000 * 3.5/100 * 4 = $280
To find the balance of the account, we add the interest earned to the principal:
Balance = P + I = $2000 + $280 = $2280

a line passing through the origin intersects the point -8 -5 what is the slope of the line
To find the slope of a line passing through the origin and a point, use the formula slope = (y2 - y1)/(x2 - x1). For a line passing through origin and the point (-8,-5), the slope is 5/8.
Explanation:The topic at hand revolves around the concept of slope and the algebra of straight lines. The slope is calculated by finding the change in y (vertical axis) over the change in x (horizontal axis). To find the slope of a line passing through the origin and the point (-8,-5), use the formula slope = (y2 - y1)/(x2 - x1).
In this case, the origin is point (0,0) and the given point is (-8,-5). So to find the slope, we substitute these values into the slope formula: slope = (-5 - 0)/(-8 - 0) = 5/8. Therefore, the slope of the line passing through the origin and the point (-8,-5) is 5/8.

Lines a is perpendicular to line b . Which statement about lines a and b is true ?
Answer:
The product of the slopes of line a and line is -1.
Perpendicular lines a and b intersect at a right angle, or 90 degrees. This is independent of whether they are increasing or decreasing, or their steepness on a graph.
Explanation:The statement about lines a and b that is true when they are perpendicular is that they form a 90-degree angle with each other. The concept of perpendicularity in geometry refers to lines, planes, or surfaces that intersect at a right angle.
Terms like increasing or decreasing line or the steepness of a line do not apply here as they pertain to the slope of the line in the context of a graph, which is distinct from the concept of perpendicularity.
For example, saying line A is a decreasing line while line B is an increasing line, does not describe their perpendicular relationship. Instead, they intersect or meet at a right angle (90 degrees), proving their perpendicular nature.

The awnser is 20 x 3
Hope this helps!
The area of a rectangle with length 4x^3 and width 5 is expressed as the monomial 20x^3 by multiplying the length and width.
To express the area of a rectangle as a monomial when given the length and width, we simply need to multiply these two dimensions together. In this case, the rectangle has a length of 4x^3 and a width of 5. The area (A) of a rectangle is given by the formula A = length * width.
So, the area of this rectangle can be calculated as:
A = 4x^3 * 5
Now, we multiply the numerical coefficients (4 and 5) and then combine them with the variable part:
A = (4 * 5) x^3
A = 20x^3
This expression, 20x^3, represents the area of the rectangle as a monomial
