What will the equation be if mowing need help. I need my lawn mowed every week from June through the middle of July. I will pay

sergij07 [2.7K]

So for the first week of june, say week 1, you have to pay then 35(1), 2nd week is 35(2), week 3 is 35(3) and week "w" say, is 35(w).

$\bf \stackrel{payment}{p}=35\stackrel{weeks}{w}\implies p=35w\qquad 1\le x\le 7$

Which of the following constants can be added to x2 + x to form a perfect square trinomial?

solmaris [256]

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

<h3>What is a quadratic equation?</h3>

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

$\rm \rightarrow x^2 + x + \dfrac{1}{4}\\\\\\\rightarrow x^2 + 2 \times \dfrac{1}{2} x + \left (\dfrac{1}{2} \right )^2\\\\\\\rightarrow \left (x + \dfrac{1}{2} \right)^2$

Sara works 40 hours per week and earns $660. Which graph shows the unit rate for this situation?

coldgirl [10]

Answer: $16.5/hour

Step-by-step explanation:

The unit rate is the relationship between y and x if x = 1

660/40 = 16.5

That means, if x = 1, y = 16.5

Therefore, <u>$16.5/hour</u>

PLZ HELP ME my teacher be buggin

Bumek [7]

We have a transversal across parallel lines so we get the usual array of congruent and supplementary angles. We just have to figure out which is which, and the diagram, even though not to scale, makes it pretty obvious.

Angle x isn't the same as the 40° angle so it must be its supplement.

Answer: C 140°

r=1.2, h=2.9, V = (1/3) πr²h

Nothing hard here, we just plug in the numbers,

V = (1/3) π (1.2)² (2.9) ≈ 4.37310

Answer: B. 4.4 cubic inches

Dilation by .5 makes a similar triangle, and reflection is an isomorphism (i.e. it doesn't change the size or shape) so the answer is

Answer: B similar not congruent

The corresponding interior and exterior angles of a triangle form a linear pair, so supplementary angles. x=180-110 = 70°

Answer: A 70°

5/4 to 3/8 as a percent change

Digiron [165]

Well, what's the diffrence from 5/4 to 3/8?

$\bf \cfrac{5}{4}-\cfrac{3}{8}\qquad \stackrel{\textit{LCD is 8 clearly}}{\implies }\qquad \cfrac{10-3}{8}\implies \cfrac{7}{8}$

so, if we take 5/4 to be the 100%, what is 7/8 off of it in percentage anyway?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{5}{4}&100\\\\
\frac{7}{8}&x
\end{array}\implies \cfrac{\quad \frac{5}{4}\quad }{\frac{7}{8}}=\cfrac{100}{x}\implies \cfrac{5}{4}\cdot \cfrac{8}{7}=\cfrac{100}{x}
\\\\\\
\cfrac{40}{28}=\cfrac{100}{x}\implies x=\cfrac{28\cdot 100}{40}$
