Answer:
Approximately 58 pieces can be cut in 35 minutes.
Step-by-step explanation:
Jason is cutting 25 firewood pieces in 15 minutes
Therefore, per minute rate of cutting firewood will be,
Rate = [tex]\frac{\text{Amount of firewood to be cut}}{\text{Time taken}}[/tex]
= [tex]\frac{25}{15}[/tex]
= [tex]\frac{5}{3}[/tex] pieces per minute
By this rate amount of firewood that can be cut = Rate × Time taken
= [tex]\frac{5}{3}\times 35[/tex]
= 58.33
≈ 58 pieces of firewood
Therefore, approximately 58 pieces can be cut in 35 minutes.
what is the answer to this equation 3 + 3/2x + 4 = 4x - 5/2x
Answer:
No solution
Step-by-step explanation:
When we take the 5/2 x to the other side, 4x and 4x cancels out. We get 7=0 which is incorrect. Therefore, x has no solution.

4.Find the length of the diagonal of a rectangle having dimensions 16 cm and 12 cm.
Answer:
20 cm
Step-by-step explanation:
So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.
Answer:
20 cm
Step-by-step explanation:
Here's your solution
=> length of rectangle = 16 cm
=> width of rectangle = 12 cm
=> Diagonal of rectangle = √(l^2 + w^2 )
=> Diagonal = √(16^2 + 12^2)
=> Diagonal = √(256 + 144)
=>. Diagonal = √400
=> Diagonal = 20 cm

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.
What is a polygon?A polygon is a closed figure made up of three or more line segments connected end to end.
A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.
So, we need to find the number of symmetrical lines a regular polygon.
A regular polygon with a sides has n lines of symmetry and order of symmetry.
Then, let a be the number of symmetrical line lines

You start at (-1,5). You move down 7 units. Where do you end?
Answer:
(-1,-2)
Step-by-step explanation:
(x,y)
Left to right = Change in x value
Left = Negative x Movement
Right = Positive x Movement
Up and Down = Change in y value
Up = Positive y Movement
Down = Negative y Movement
if x = -1, y = 5

Answer:
Step-by-step explanation:
The quadratic formula would be the following...
[tex]x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}[/tex]
where the original quadratic equation would be represented as follows
[tex]ax^{2} + bx +c = 0[/tex]
Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.
[tex]\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}[/tex]
That would be the correct order for the values.
5x + 19.95 = 35
Solve x
Answer:
X = 3.01
Step-by-step explanation:
To solve for x, you first need to get x by itself. So you would minus 19.95 from both sides. Which would then be
5x = 15.05
Again x is not by itself so you would divide both sides by 5, the eqation would then be
x = 3.01
Which is the answer. If you want you can double check your work by putting the answer back in the eqaution.
5(3.01) + 19.95 = 35
If the statement is true that means you have the right answer
15.05 + 19.95 = 35
35 = 35
We are correct! Hope this helps with your question and how to do others like it.

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. What is the probability that a student who has a brother also has a sister?
Answer: 11
Students have both a brother and a sister
Step-by-step explanation:
I don't think probability should be used for this question because the answer is quite clear
So in a class of 25 students
5 students don't have a sibling
So 25-5=20
Total number of siblings=14+17=31 siblings in total
So 20 people have 31 siblings
31-20=11
So the answer should be 11
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.
In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.
So in a class of 25 students
5 students don't have a sibling
then, 25-5=20
Total number of siblings = 14+17
= 31 siblings in total
So, 20 people have 31 siblings
= 31 - 20
= 11
So, the probability that a student who has a brother also has a sister
= 11/ 25.

Answer:
FIND X AND PLUG IT IN
You basically put x+12+2x+3+90=180 and solve for x. Then when you find x plug it in x+12 to find a and 2x+3 to find c.
Answer:
angle A is 37°
angle C is 53°
Step-by-step explanation:
The angles x+12 and 2x+3 add to 90°, because there is already a right angle in the triangle and the total angles in a triangle add to 180°
x+12+2x+3=90
3x+15=90
3x=75
x=25
Knowing x=25°, we can substitute it back into angle A and C.
A: 25+12=37°
C: 2(25)+3=50+3=53°
2) What x value makes the exponential function greater than the
quadratic function?
A)X = -2
B)x = 0
X = 2
D) =4
Answer:
The answer is b
Step-by-step explanation:
X= 0 makes the exponential function greater than the quadratic function. Therefore, the correct option is option B.
What is exponential function?The mathematical symbol for the exponent is [tex]e^{X}[/tex]. The word, unless specifically stated differently, generally relates to the positive-valued functional of something like a real variable, though it can be extended towards the complex numbers or adapted to other mathematical like matrices or Lie algebras.
The idea of exponentiation is where the exponential function got its start, although recent definitions allow for a rigorous extension to all real arguments, especially irrational values. X= 0 makes the exponential function greater than the quadratic function.
Therefore, the correct option is option B.
