4X-8 + 6x +13= 90 ¿cual es le resultado ?

eimsori [14]

4x - 8 + 6x + 13 = 90
4x + 6x = 90 + 8 - 13
10 x = 85
10x/10 = 85/10
x = 8.5

Write equations for the horizontal and vertical lines passing through the point (-6,1)

Oksanka [162]

Answer:

y = 1 and x = - 6

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c ( where c is the value of the y- coordinates the line passes through )

The line passes through (- 6, 1 ) with y- coordinate 1 , then

y = 1 ← equation of horizontal line

The equation of a vertical line parallel to the y- axis is

x = c ( where c is the value of the x- coordinates the line passes through )

The line passes through (- 6, 1 ) with x- coordinate - 6 , then

x = - 6 ← is equation of vertical line

Pyramid A and Pyramid B are similar. Pyramid A has a volume of 648 m and Pyramid B has a

ryzh [129]

Answer:

the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$

Step-by-step explanation:

Given the information:

Pyramid A : 648 $m^{3}$
Pyramid B : 1,029 $m^{3}$
Pyramid A and Pyramid B are similar

As we know that:

If two solids are similar, then the ratio of their volumes is equal to the cube

of the ratio of their corresponding linear measures.

<=> $\frac{Volume of A }{Volume of B}$ = $(\frac{a}{b}) ^{3}$ = $\frac{684}{1029}$ = $\frac{216}{343}$

<=> $\frac{a}{b} =$ $\frac{6}{7}$

Howver, If two solids are similar, then the n ratio of their surface areas is equal to the square of the ratio of their corresponding linear measures

<=> $\frac{surface area of A}{surface area of B} =( \frac{a}{b}) ^{2}$

= $\frac{36}{49}$

So the ratio of the surface area of Pyramid A to Pyramid B is: $\frac{36}{49}$
