Answer:

9 and 10

Step-by-step explanation:

square root of 96 is 9.79795897113

Answer:

9 and 10

Step-by-step explanation:

because square of 9 is 81

and square of 10 is 100

81<96<100

so it lies between 9 and 10

Answer: 15 years

Step-by-step explanation:

Given

Difference between [tex]\frac{3}{5}[/tex] Raman's present age and his age 4 years ago is 0

Suppose Raman's present age is [tex]x[/tex]

So, we can write

[tex]\Rightarrow \dfrac{3x}{5}-(x-4)=0\\\Rightarrow \dfrac{3x-5x}{5}+4=0\\\Rightarrow \dfrac{-2x}{5}+4=0\\\Rightarrow x=\dfrac{20}{2}=10[/tex]

His age after 5 years is [tex]x+5=15\ yr[/tex]

Answer:

176.25in^2

Step-by-step explanation:

You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.

7.5*16=120 (left side)

7.5*7.5=56.25 (right side)

Now we add them to get the full area:

120+56.25=176.25in^2

Write the system as an augmented matrix:

[tex]\left[\begin{array}{cc|c}1&5&22\\4&-7&7\end{array}\right][/tex]

Add -4 (row 1) to row 2 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&-27&-81\end{array}\right][/tex]

Multiply row 2 by -1/27 :

[tex]\left[\begin{array}{cc|c}1&5&22\\0&1&3\end{array}\right][/tex]

Add -5 (row 2) to row 1 :

[tex]\left[\begin{array}{cc|c}1&0&7\\0&1&3\end{array}\right][/tex]

Then x = 7 and y = 3.

Respuesta:

3.3 × 10⁴ m

Explicación paso a paso:

Paso 1: Información provista

Superficie de la parcela cuadrada (S): 1089 km²

Paso 2: Determinar la longitud del lado (l) de la parcela

Podemos determinar la superficie de un cuadrado usando la siguiente fórmula.

S = l²

l = √S = √1089 km² = 33 km

Paso 3: Convertir "l" a metros

Vamos a usar el factor de conversión 1 km = 10³ m.

33 km × 10³ m/1 km = 3.3 × 10⁴ m

Answer:

x + 3y = 23

Step-by-step explanation:

m = -1/3, find 'b'

5 = -1/3(8) + b

15/3 = -8/3 + b

23/3 = b

y = -1/3x + 23/3

multiply each side by 3 to get:

3y = -x + 23

x + 3y = 23

Answer:

Solution given:

A(a,b) lie in 6x-y =1

substituting value of A in equation ,we get

6a-b=1...................(1)

B(b,a) lie in 2x - 5y = 5

substituting value of B in equation ,we get

2b-5a=5

b=5(a+1)/2............(2)

substituting value of b in equation 1 ,we get

6a-5(a+1)/2=1

12a-5a-5=2

7a=2+5

a=[tex] \frac{7}{7} [/tex]=1

substituting value of a in equation 1 ,we get

6×1-b=1

6-1=b

b=5

so points are A(1,5) and B(5,1)

we have

equation of line having two points

[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]

[tex](y - 5) = \frac{1-5}{5-1} (x - 1) [/tex]

[tex](y - 5) = -1 (x - 1) [/tex]

y-5=1-x

x+y=6 is a required equation of line AB.

The delivery company's statistics on the average driving miles show that the true statements are:

Z score for 99% confidence interval is 2.576 so this can be found as:

= 85.6 ± (2.576 x 9.85) / √50

= (82.01 to 89.19)

Z score for 95% confidence interval is 1.960 so this can be found as:

= 85.6 ± (1.96 x 9.85) / √50

= (82.87 to 88.33)

With a Z score of 1.960:

= (1.96 x 9.85) / √50

= 2.70 miles

= (2.576 x 9.85) / √50

= 3.59 miles

The correct options are therefore 2 and 5.

Answer:

  b.  2692 ft

Step-by-step explanation:

The relation of interest between the sides of the right triangle is ...

  Tan = Opposite/Adjacent

Using the given numbers, that is ...

  tan(32°) = (building height)/(4300 ft)

Multiplying by 4300 ft, we get ...

  building height = (4300 ft)·tan(32°) ≈ 2686.9 ft

This is the height above the observer's eyes, so the height of the building above the ground is ...

  2687 +5 = 2692 . . . . feet

The building is 2692 feet tall.

Answer:

A-3/4=1/8 is the equation, if you expand 3/4 it is 6/8, in order to get 1/8 you need to subtract 6/8 from 7/8

7/8-6/8=1/8 therefor A=7/8
