Answer:
She needs to cut the log 11 times
Step-by-step explanation:
hope that helps!!!
There are 11 cuts are necessary for equally spaced cuts.
What is mean by Subtraction?Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
Susan wants to cut a log into 12 pieces with equally spaced cuts.
Hence, To cut 12 pieces with equally spaced cuts, number of cuts are,
⇒ 12 - 1
⇒ 11
Thus, There are 11 cuts are necessary for equally spaced cuts.

There are 17 female students in a chemistry class. If the class is 54.84% female, how
students are in the chemistry class?
many total students are in the chemistry class?
Answer:
there are 14 boys and 31 total students in chemistry class.
explanation:
total number of students: 100%
total number of students:
[tex]\frac{17}{54.84} * 100[/tex]31 students total.Boys in the class:
100% - 54.84%45.16%Boys total:
31 * 45.16%14 boy students.There are 14 boys and 31 total students in the chemistry class.
It is given that there are 17 female students which is also equal to 54.84 % of total students in chemistry class.
We have to find the total number of students and number of boys in chemistry class.
What will be the 50 % of 100 ?
The value will be 50.
Let's assume that total number of students be x.
∵ Number of female students ;
⇒ 54.84 % of x = 17
⇒ (54.84/100) × x = 17
⇒ x = 1700 ÷ 54.84
⇒ x = 31 (approximate)
So, the total number of students in chemistry class are 31.
&
Number of boys = 31 - 17 = 14
Thus , there are 14 boys and 31 total students in the chemistry class.

find the value of b and give reasoning in the image below
Answer:
b = 104°
Step-by-step explanation:
<DEA = <DAE (given)
Now,
<DEA + 142 = 180° (linear pairs)
<DEA = 180° - 142°
so, <DEA = 38°
Now,
<DEA + <DAE + b = 180° (sum of angles of triangle)
or, 38° + 38° + b = 180° (<DEA = <DAE)
or, b = 180° - 76°
so, b = 104°

Determine all solutions to the equation 1 over sine theta equals 2 times sine theta on the interval [0, 2π).
The solution to the trigonometric equation in the interval is given by:
[tex]x = \frac{\pi}{4}[/tex]
What is the trigonometric equation?In this problem, the equation is given by:
[tex]\frac{1}{\sin{\theta}} = 2\cos{\theta}[/tex]
Applying cross multiplication, we have that:
[tex]2\sin{\theta}\cos{\theta} = 1[/tex]
Applying a trigonometric identity, we have that:
[tex]\sin{2x} = 1[/tex]
We have that on the interval [0, 2π), [tex]\sin{\left(\frac{\pi}{2}\right)} = 1[/tex]
Hence:
[tex]\sin{2x} = 1[/tex]
[tex]\sin{2x} = \sin{\left(\frac{\pi}{2}\right)}[/tex]
[tex]2x = \frac{\pi}{2}[/tex]
[tex]x = \frac{\pi}{4}[/tex]
For [tex]\frac{3\pi}{4}[/tex], we have that:
[tex]\sin{2x} = \sin{\left(\frac{3\pi}{2}\right)} = -1[/tex]
Hence only the first solution is correct.

Choose the equation of the line in slope-intercept form.
Parallel to y = 3x - 1 and has the point (-2,-1).
A. y = -1/3x + 2
B. y = -1/3x + 5
C. y = 3x + 5
D. y = 3x + 2
answer:
y = 3x + 5
steps-explanation:
given sample equation:
y = 3x - 1comparing to the formula of slope intercept form: y = mx + b
[ where m is the slope and b is the y-intercept ]
we can determine here that the slope is 3 and -1 is the y-intercept.
but here we need only the slope.
in parallel, the slope is same: 3
formula:
y - y1 = m(x - x1)using the formula: [ here known that y1 is -1 and x1 is -2 ]
y - -1 = 3(x - -2)y + 1 = 3x + 6y = 3x + 5A farmer's truck is carrying 42/3 tons of hay and straw. If 325 tons of the load is

What’s the correct answer for this question? Any help is appropriated
Answer:
Step-by-step explanation:
we want to set the per ... value to one
so for the dollars per pound we find how many dollars per one pound. we can set up a proportion to do so.
(6.79/16) = (x/1) so we can solve that by finding (6.79/16)(1) = x meaning x is 0.424 [3 sig figs] meaning its 0.424 dollars per pound
using the same process we find the other proportion which would be (16/6.79) = (x/1) -> (16/6.79)(1) = x -> 2.36 meaning 2.36 pound per dollar

please check this. I suck at math.
Problem 1
You have the correct y value, but it refers to pizzas (not salads).If you need to convert to a mixed number, then follow these steps.
27.2 = 27 + 0.2
27.2 = 27 + 1/5
27.2 = 27 & 1/5
27.2 pizzas is the same as 27 & 1/5 pizzas. In other words, you have 27 whole pizzas plus 1/5 of an extra one.
===========================================
Problem 2
This is correct.The decimal 1.75 converts to the mixed number 1 & 3/4 because of the steps below.
1.75 = 1 + 0.75
1.75 = 1 + 3/4
1.75 = 1 & 3/4
In my opinion, it is optional to convert to a mixed number for either problem 1 or problem 2. So you can stick with 1.75 as the answer if you want.
===========================================
Problem 3
16 & 3/4 = 16 + 3/4 = 16 + 0.75 = 16.75
To get the unit rate, which is the cost per unit, we divide the total cost over the amount.
cost/amount = (2.89)/(16.75) = 0.1725373
which is approximate.
Round to the nearest penny to get a unit cost of $0.17 per fluid ounce, i.e. a unit cost of 17 cents per fluid ounce.
Answer: $0.17 or 17 cents===========================================
Problem 4
We follow the same idea as problem 3.
4 & 3/5 = 4 + 3/5 = 4 + 0.6 = 4.6
unit cost = (total cost)/(amount)
unit cost = (7.56)/(4.6)
unit cost = 1.643478 dollars approximately
unit cost = 1.64 dollars approximately
Answer: $1.64===========================================
Problem 5
6 & 1/2 = 6 + 1/2 = 6 + 0.5 = 6.5
Like before, we'll divide the total cost over the total amount.
unit cost = (total cost)/(amount)
unit cost = (8.22)/(6.5)
unit cost = 1.264615 dollars approximately
unit cost = 1.26 dollars approximately
Answer: $1.26===========================================
Here's another way to look at the unit cost or unit rate.
Notice in problem 5 it says "cost per yard". This is the same as "cost per 1 yard" or "cost for each yard".
We can express the given info as the ratio
6.5 yards:$8.22
Now we want the "6.5 yards" to become "1 yard" to achieve the unit rate.
So we'll divide both parts by 6.5
6.5 yards:$8.22
6.5/6.5 yards:$8.22/6.5
1 yard: $1.26 approximately
For each yard, we'll spend $1.26
Problems 3 and 4 follow similar ideas. So this is why we divided the total cost over the total amount.

Answer:

Step-by-step explantion
Simplifying
2x + 3 + 25 = 3x + -17
Reorder the terms:
3 + 25 + 2x = 3x + -17
Combine like terms: 3 + 25 = 28
28 + 2x = 3x + -17
Reorder the terms:
28 + 2x = -17 + 3x
Solving
28 + 2x = -17 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
28 + 2x + -3x = -17 + 3x + -3x
Combine like terms: 2x + -3x = -1x
28 + -1x = -17 + 3x + -3x
Combine like terms: 3x + -3x = 0
28 + -1x = -17 + 0
28 + -1x = -17
Add '-28' to each side of the equation.
28 + -28 + -1x = -17 + -28
Combine like terms: 28 + -28 = 0
0 + -1x = -17 + -28
-1x = -17 + -28
Combine like terms: -17 + -28 = -45
-1x = -45
Divide each side by '-1'.
x = 45
Simplifying
x = 45
Answer:
x = 45Step-by-step explanation:
Exterior angle is same as sum of two remote interior angles:
