Answer:

D) 5

Step-by-step explanation:

This is the median of the trapezoid. It is the line segment that connects the midpoints of the non-parallel sides of the trapezoid.

The length of the median of a trapezoid is equal to 1/2 the sum of the bases; this makes ours

1/2(3.3+6.7) = 1/2(10) = 5

Answer: D. 5

Step-by-step explanation:

In the given figure , we have give a trapezioid ABCD with parallel sides BC= 3.3 units and AD= 6.7 units.

Also, E and F appears as the mid points of non parallel sides AB and CD and parallel to the bases BC and AD.

⇒ EF would be the median of trapezioid ABCD.

Also, we know that , the length of the median of a trapezoid equals to one-half the sum of the lengths of the two bases.

i.e. length of EF = $\dfrac{1}{2}(AD+BC)$

i.e. length of EF = $\dfrac{1}{2}(6.7+3.3)$

i.e. length of EF = $\dfrac{1}{2}(10)$

i.e. length of EF = 5 units.

7. Find the distance between the points (13, 8) and (-12, 6)

Alik [6]

Answer:

√629 ≈ 25.08

Step-by-step explanation:

The distance formula is useful for this.

d = √((x2 -x1)² +(y2 -y1)²)

d = √((-12 -13)² +(6 -8)²) = √(625 +4) = √629 ≈ 25.08

The distance between the points is about 25.08 units.

Answer:

So the vaule of y is 7, 10 & 13

Step-by-step explanation:

Given that y = 3x+1 . So we can just substitute x-value into the equation :

Let x=2,

y = 3(2)+1

= 7

Let x=3,

y = 3(3)+1

= 10

Let x=4,

y = 3(4)+1

= 13

A construction firm is trying to decide which of two models of a crane to purchase. Model A costs $90,000 and requires $4,000 pe

liraira [26]

Let's say hmm let's use the figures in thousands, so
model A costs 90 + 4 per year, so... ok.. after "t" years, then the cost for model A is then 90 + 4*t, or A = 90 + 4t.

now, model B is 70 + 10 per year, so,... after "t" years, model B is then
B = 70 + 10 * t, or B = 70 + 10t.

if we were to assume A < B, namely the cost of A is less than B, what would the years be? namely, what's "t"?

$\bf A\ \textless \ B\implies 90+4t \ \textless \ 70 + 10t\implies 90-70 \ \textless \ 10t-4t
\\\\\\
20 \ \textless \ 6t\implies \cfrac{20}{6}\ \textless \ t\implies \cfrac{10}{3}\ \textless \ t\implies 3\frac{1}{3}\ \textless \ t
\\\\\\
\textit{3 years and }\frac{1}{3}\textit{ or \underline{3 years and 4 months}}$

after that period, then A becomes cheaper than B.
