Solve the system of equations using elimination. SHOW WORK!!!!!!!!!!!!!

irinina [24]

q= 6

r= 7

work--

Multiply 1st column by -2:

-30q+8r=-124

5q+8r=86

Subtract 2nd column from the first column:

-35q= -210

Solve for q:

q=6

Subtract q=6 by any of the two equations, so:

-30q+8r=-124

-30*6+8r=-124

Solve for r:

r=7

Answer:

33.4933 ≈ 33.5 mm³

Step-by-step explanation:

Given that,

→ Radius (r) = 2 mm

Formula we use,

→ 4/3 πr³

Let's solve for the volume of sphere,

→ 4/3 πr³

→ 4/3 × 3.14 × 2 × 2 × 2

→ 4/3 × 3.14 × 8

→ 4/3 × 25.12

→ 100.48/3

→ 33.4933

→ [ ≈ 33.5 mm³ ]

Hence, volume of sphere is 33.5 mm³.

Can someone help me with this ?

Answer:

$\large\boxed{S.A.=467\ in^2}$

Step-by-step explanation:

We have two triangles and three rectangles.

The formula of an area of a triangle:

$A_{triangle}=\dfrac{bh}{2}$

b - base

h - height

The formula of an area of a rectangle:

$A_{rectangle}=lw$

l - length

w - width

TRIANGLE:

b = 11 in, h = 7 in

$A_1=\dfrac{(11)(7)}{2}=\dfrac{77}{2}=37.5\ in^2$

RECTANGLE 1:

l = 11 in, w = 14 in

$A_2=(11)(14)=154\ in^2$

RECTANGLE 2:

l = 9 in, w = 14 in

$A_3=(9)(14)=126\ in^2$

RECTANGLE 3:

l = 8 in, w = 14 in

$A_4=(8)(14)=112\ in^2$

The Surface Area:

$S.A.=2A_1+A_2+A_3+A_4$

Substitute:

$S.A.=2(37.5)+154+126+112=467\ in^2$
