Answer:
1 hour
Step-by-step explanation:
100 is 4 times more than 25.
Answer:
1 hours
Step-by-step explanation:
By concept we know it takes a person to complete a job of three person more time. so we shall multiply in this question.
if 25 men takes 4 hours
1 men will take 4 * 25 = 100 hours
100 men takes = ( 100 ÷ 100 ) hours = 1 hours
It takes 1 hours for 100 men to build the same wall.Brian gets £x wages each week. After he pays his tax of £t, he then pays his rent of £155. He shares what's left between himself and his wife. How much do they each get?
Answer:
[tex]\frac{1}{2}(x-t-155)[/tex]
Step-by-step explanation:
Total wages: [tex]x[/tex]
Pays tax [tex]t[/tex]: [tex]x-t[/tex]
Pays rent of 155: [tex]x-t-155[/tex]
Shares what's left between 2: [tex]\frac{x-t-155}{2}[/tex]
So each gets: [tex]\frac{1}{2}(x-t-155)[/tex]

A coffee table is on sale for 20% off the original price of $115. If there is 7.5% sales tax, what is the final price of the coffee table? HURRY ILL GIVE BRAINLIEST IF CORRECT
Answer:
98.9
Step-by-step explanation:
115 - 20% = 92
92 + 7.5% = 98.9
Answer:
the original price is 115 after we subtract 20% we are left with 92 so now
the price of the coffee table is 92 but with 7.5% as tax, the final price is $98.90 since 7.5% of 92 is 6.90
The graph of F(x) shown below resembles the graph of G(x)= x4, but it has
been vertically stretched. Which of the following could be the equation of F(X)
?
Answer:
x = 0.Equation:
[tex]g*(x)-(x^4)=0[/tex]Step-by-step explanation:
Step 1:
Pull out like factors:[tex]gx - x^4 = x * (g - x^3)[/tex]Trying to factor as a Difference of Cubes:
Factoring: [tex]g - x^3[/tex]Theory : A difference of two perfect cubes, a^3 - b^3 can be factored into (a-b) • (a^2 +ab +b^2)Proof : (a-b)•(a^2+ab+b^2) = a^3+a^2b+ab^2-ba^2-b^2a-b^3 = a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3 = a^3+0+0-b^3 = a^3-b^3Check : g^1 is not a cube !!Ruling : Binomial cannot be factored as the difference of two perfect cubesEquation at end of step 1:
[tex]x * (g - x^3) = 0[/tex]Step 2:
A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product Any solution of term = 0 solves product = 0 as well.Solving a Single Variable Equation:
Solve [tex]g - x^3 = 0[/tex]In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.We shall not handle this type of equations at this time.Solution:
x=0.find an equation in point-slope form form the line having the slope m = -4 and containing the point (3,5)
Answer:
y = 17 - 4x or y = 17 + (-4x)
Step-by-step explanation:
Plug the slope (m) into the equation y=mx+b so it becomes y = -4x + b
Then see how much your line changed from the point to the y-axis. In this case, it changed by negative 12. So you have to go up 12 points to reach the y-intercept. (5+12=17)
Then, plug that number into the equation.
y = 17 - 4x

What is an equation of the line that passes through the point (-7, -6) and is parallel to the line x-y=7?
If you’re answer is correct, I WILL GIVE BRAINLIEST!!! Thank you!:)
Answer:
Step-by-step explanation:
For two lines to be parallel their slopes must be equal. For two lines to be perpendicular their slopes must be the negative reciprocal of each other.
Step 1 Find the slope of the equation.
Put it into the slope-intercept form. y = mx + b.
For x-y = 7, move the x to the left; therefore subtract the x from both sides. this leaves you -y = -x + 7
Then, divide both sides by -1 to get a positive y. -y/-1 = (-x + 7)/-1
This leaves y = x - 7 The slope(m) for this equation is m = 1
The other equation must also have a slope of 1 or m=1 for the lines to be parallel.
Use the point given to you (-7, -6) and substitute for (x, y)
The slope-intercept form y = mx + b can once again be used.
x = -7, y =-6, and slope or m = 1
Therefore, y = mx + b substituted will be -6 = (1)(-7) + b; now, solve for b which is the y intercept
-6 = -7 + b add 7 to both sides -6 +7 = -7 + b +7 ; therefore, b = 1
Now you know the slope(m) which is equal to 1 and the y-intercept(b) which is equal to 1.
Finally, substitute the m and b in the slope-intercept form
y = (1)x + 1 or y = x +1
- A six-foot diameter circular table
top has an area of about how many

Answer to these 2 questions pls fast!
Step-by-step explanation:
17.
an addition is commutative. that means the sequence of the arguments of the operation does not matter (as long as the arguments are truly the same).
7x + 1 = 1 + 7x
1 = 1
0 = 0
is all true for any and every value of x.
so, yes, that's how I know that the expressions are equivalent.
18.
no, the case of 17 does not apply, because she changed the arguments of the addition (not just the sequence).
to check :
7x + 1 = 1x + 7
6x = 6
x = 1
this is true for exactly one value of x. but definitely not fit every value of x.
and so, these 2 existing are not equivalent. they are 2 different functions with a crossing point.
determine if each statement must be true could possibly be true or definitely not true explain or show your reasoning
a. isosceles triangles are similar b. equilateral triangles are similar
Answer:
Equilateral triangles are always similar, whereas isosceles triangles are not necessarily comparable.
The angles in one triangle must have the same values as the angles in the other triangle for two triangles to be identical. The lengths of the sides must be proportional.
Both may be isosceles, however one may have 30°, 30°120° angles and the other may have 20°, 20° 140° angles.
As a result, isosceles triangles are not necessarily comparable.
Because equilateral triangles always have three angles of 60 degrees apiece, any
All equilateral triangles are always similar and isosceles triangles are not always similar.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
A) No, all isosceles triangles are not similar. An isosceles triangle is a triangle with two sides of equal length. For all isosceles triangles to be similar, it would have to be the case that the ratios comparing the lengths of corresponding sides of all isosceles triangles are the same.
B) Yes. All equiangular triangles are similar. In geometry, we have a nice theorem that allows us to determine if two triangles are similar using the measures of their corresponding angles.
All equilateral triangles are always similar. Similar triangles are always congruent.
Therefore, all equilateral triangles are always similar and isosceles triangles are not always similar.

My best interpretation of the math here is that you're talking about the line integral,
[tex]\displaystyle \int_C \left(y+e^{\sqrt x}\right) \, dx + \left(2x + \cos\left(y^2\right)\right) \, dy[/tex]
I won't bother trying to decipher what look like multiple choice solutions.
By Green's theorem, the line integral above is equivalent to
[tex]\displaystyle \iint_D \frac{\partial\left(2x+\cos\left(y^2\right)\right)}{\partial x} - \frac{\partial\left(y+e^{\sqrt x}\right)}{\partial y} \, dx \, dy[/tex]
where D is the set

Compute the double integral:
[tex]\displaystyle \int_0^1 \int_0^{x^2} \left(2 - 1\right) \, dy \, dx = \int_0^1 \int_0^{x^2} dy \, dx = \int_0^1 x^2 \, dx = \boxed{\frac13}[/tex]

Algebra 1: I think it's about exponential growth.
Answer:
Step-by-step explanation:
The given equation assumes a 12 cubic inch initial volume. The question wants to know when, in minutes, the volume, y, reaches 36 in^3:
y = 12*(2)^(t/60), where t is time in minutes
Therefore:
36 = 12*(2)^(t/60)
3 = (2)^(t/60)
log(3) =(60/t) log(2)
t = 60log(3)/log(2)
t = 95.1 minutes
