Answer

18,080

Explantion

400x10=4000x4=16000

400x5=2000

2000+16000=18000

400×.2=80

cause 20% of 400 is 80

so total is 18,080

Answer:

[tex]\sf y \leq \dfrac34x[/tex]

Step-by-step explanation:

Choose 2 points on the line:  (0, 0) and (4, 3)

[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-0}{4-0}=\dfrac34[/tex]

point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac34(x-0)[/tex]

[tex]\implies \sf y=\dfrac34x[/tex]

Solid line : ≤ or ≥

Dashed line: < or >

Therefore as the line is solid, and the shading is below the line,

[tex]\implies \sf y \leq \dfrac34x[/tex]

Slope:-

[tex]\\ \tt\Rrightarrow m=\dfrac{6+3}{8+4}=\dfrac{9}{12}=\dfrac{3}{4}[/tex]

Equation of line in point slope form

[tex]\\ \tt\Rrightarrow y+3=3/4(x+4)[/tex]

[tex]\\ \tt\Rrightarrow y+3=3/4x+3[/tex]

[tex]\\ \tt\Rrightarrow y=3/4x[/tex]

equation of shaded region

[tex]\\ \tt\Rrightarrow y\leqslant 3/4x[/tex]

Answer:

[tex]1\frac{5}{12}[/tex]

Step-by-step explanation:

[tex]1\frac{2}{3}-\frac{1}{4}[/tex]

[tex]\mathrm{Subtract\;Whole\;Number}[/tex]

[tex]1-0=1[/tex]

[tex]\mathrm{Combine\;fraction}[/tex]

[tex]\frac{2}{3}-\frac{1}{4}:\frac{5}{12}[/tex]

[tex]=1+\frac{5}{12}[/tex]

[tex]=1\frac{5}{12}[/tex]

Hence, the answer is 1 5/12

~Lenvy~

1. Convert the 1 and 2/3 from mixed partial fractions to improper fractions to make it a bit simpler to calculate

⇒ [tex]1\frac{2}{3} = \frac{5}{3}[/tex]

2. Now lets the change the base of both fractions into a common denominator and solve

⇒ [tex]\frac{5}{3}-\frac{1}{4} = \frac{5*4}{3*4} -\frac{1*3}{4*3} =\frac{20}{12}-\frac{3}{12} =\frac{20-3}{12} =\frac{17}{12} = 1\frac{5}{12}[/tex]

Answer: [tex]\frac{17}{12}[/tex] or [tex]1\frac{5}{12}[/tex]

Answer:

v = [tex]\frac{7\sqrt{2} }{2}[/tex]

u = [tex]7[/tex]

Step-by-step explanation:

First, the angle on the far left is also 45 degrees.

So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.

However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].

So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:

[tex]7[/tex]

Hope this helps!

Step-by-step explanation:

this sequence has 8 terms and the common ratio or multiplication factor is -1/2.

we could add these 8 numbers manually or use the formula :

Sn = a1(1 - r^n)/(1 - n)

when r < 1 (like in our case -1/2).

S8 = 128(1 - (-1/2)⁸)/(1 - -1/2) =

= 128(1 - 1/256)/(3/2) = (128×255/256)/(3/2) =

= (255/2)/(3/2) = 255/2 × 2/3 = 255/3 = 85

Answer:

If you mean [tex]\sqrt{ab^{2}[/tex] then the answer is [tex]b\sqrt{a}[/tex]

Step-by-step explanation:

Answer:

ab

Step-by-step explanation:

Original expression:

[tex]\sqrt[]{(ab)^2}[/tex]

Apply the rule [tex](xy)^c=x^c \cdot y^c[/tex]

[tex]\implies \sqrt[]{(ab)^2}=\sqrt[]{a^2 \cdot b^2}[/tex]

Apply the rule [tex]\sqrt{xy}=\sqrt{x} \sqrt{y}[/tex]

[tex]\implies \sqrt[]{a^2 \cdot b^2}=\sqrt{a^2} \sqrt{b^2}[/tex]

Apply the rule [tex]\sqrt{x^2}=x[/tex]

[tex]\implies \sqrt{a^2} \sqrt{b^2}=ab[/tex]
