If PQ || to BC

Then by BASIC PROPORTIONALITY THEOREM:

\frac{8}{40}  =  \frac{x}{45}  \\  \\  \frac{1}{5}  =  \frac{x}{45}  \\  \\ x =  \frac{45}{5}  \\  \\ x = 9

Find a point-slope form for the line with slope 1/5 and passing through the point (- 4. - 8).
andrew11 [14]

Answer:

y+8 = 1/5(x+4)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y- -8 = 1/5(x - -4)

y+8 = 1/5(x+4)

The circumference of a
timama [110]

9514 1404 393

Answer:

  • 160,000 m²
  • 16 ha

Step-by-step explanation:

The side length of a square is 1/4 of the perimeter, so the side length of the square orchard is (1600 m)/4 = 400 m.

The area of a square is the square of the side length, so the area of the orchard is (400 m)² = 160,000 m².

A hectare is 10,000 m², so the area of the orchard in hectares is ...

  16·(10,000 m²) = 16 ha

Can someone help me with this question "Given the triangle below, what is m (angle) < B, rounded to the nearest tenth?
JulsSmile [24]
The answer
the sum of the angles in a triangle is always 180°
m < B + m < A + m < C = 180°,  
let's find m < B, 
by applying sinus rule 
 14/sinB=10/sinC, so sinB= 10xsinB = 14 x sinC and therefore, 
sinB=( 14/10 )sinC =7/2 sin 36° =0.82, so arcsinB=55.08°
the answer is C 55.4°

Which expression is equivalent to 6+4.5(32f-14f)
vichka [17]

Answer:

6 + 4.5(32f - 14f) = 6 + 81f

Step-by-step explanation:

Let us apply the distributive property to find an equivalent expression for:

6  + 4.5(32f - 14f)

For all real numbers a, b, and c, the distributive property says that:

a(b + c) = ab + ac

We apply this property to get:

6 + 4.5(32f - 14f) = 6 + 4.5 \times 32f  + 4.5 \times  - 14f

6 + 4.5(32f - 14f) = 6 + 144f   - 63f

We simplify the RHS to get:

6 + 4.5(32f - 14f) = 6 + 81f
