P%= \frac{p}{100}

\frac{15}{100} =  \frac{15\div5}{100\div5} =  \frac{3}{20}

\frac{3}{20} *x=84 ⇒ 3x=84*20
3x=1680
So, x=\frac{1680}{3} = 560

\boxed {x=560}

<em /><em>x*15/100=84
x=84*100/15
x=8400/15
x=560
therefore the number is 560

The simplified form of the difference quotient of equation 9x^2+5x-1 . in the form 9x + 9h + 5.

In question for equation 9x^2+5x-1, simplified to difference quotient in the form of Ax+Bh+C where A, B, C are integers

<h3>What is equation?</h3>

equation is the relationship between variable and represented as  9x^2+5x-1  is example of polynomial equation.

We know that,
for difference quotient
=\frac{f(x+h)-f(x)}{h} \\\frac{9(x+h)^2+5(x+h)-1-9x^2-5x+1}{h}\\\frac{9h^2+9hx+5h}{h}\\9x+9h+5
While, compared with Ax+Bh+C
we have A=9, B=9, C=5.

Thus, The required value of difference Quotient in the form Ax+Bh+c where A, B and C is 9, 9 and 5 respectively

Pls help im pretty sure its easy i just forgot
dalvyx [7]

the average can be calculated by adding the scores together and then dividing by the number of scores.

we can set up an equation:

let x = test score needed on next test

(72+72+80+x)/4 = 71

multiply both sides by 4

72+72+80+x = 284

add like terms

224+x=284

subtract 224 from both sides

x=60

she will need a 60 for her average to be 71

10. A 50-ft ladder leans against a building so that the base of the ladder is 15 feet from the
Hunter-Best [27]

By applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°

<em><u>Recall:</u></em>

  • Trigonometry ratios that can be used to solve a right triangle are: SOH CAH TOA.
  • SOH represents: sin ∅ = Opp/Hyp
  • CAH represents: cos ∅ = Adj/Hyp
  • TOA represents: tan ∅ = Opp/Adj

The diagram attached below depicts the problem given.

∅ = x

Opp = 15 ft

Hyp = 50 ft

  • Thus, applying the trigonometry ratio, SOH, we have:

sin x = 15/50

x = sin^{-1}(15/50)

x = 17.5°

In conclusion, by applying the trigonometry ratio, SOH, the angle that the ladder makes with the building is calculated as: 17.5°
