The area of a rectangle is 28 m', and the length of the rectangle is 1 m more than twice the width. Find the dimensions of the r

Marianna [84]

Answer:

8m ×3.5m

Step-by-step explanation:

Area of rectangle= length ×width

Let the length and width of the rectangle be L and W meters respectively.

Area of rectangle= LW

LW= 28 -----(1)

L= 2W +1 -----(2)

Subst. (2) into (1):

(2W +1)(W)= 28

Expand:

2W² +W= 28

-28 on both sides:

2W² +W -28= 0

Factorise:

(W +4)(2W -7)= 0

W +4=0 or 2W -7=0

W= -4 (reject) or W= 3.5

Substitute W= 3.5 into (2):

L= 2(3.5) +1

L= 7 +1

L= 8

∴ The dimensions of the rectangle is 8m ×3.5m.

Given the figure shown at the right ABC is a triangle, what would be the measure of the unknown exterior angle (labeled x in the

Andre45 [30]

Answer:

d. 112°

Step-by-step explanation:

m<A = 64° (given)

m<ABC = 180° - 132° (linear pair)

m<ABC = 48°

According to the exterior angle theorem of a triangle, the exterior angle of a ∆ is equal to the opposite interior angles of the ∆.

48° and 64° are interior angles of ∆ABC that are opposite to the exterior angle, x.

Therefore,

x = 48 + 64

x = 112°

The probability that someone owns an iPhone is 62%. The probability that someone owns an Apple watch is 15%. The probability som

Dmitry [639]

ANSWER

The probability that someone owns an iPhone or an Apple watch is

$P(I \cup \: A) = 69\%$

or

$P(I \cup \: A) = 0.69$

EXPLANATION

We were given that, the probability that someone owns an iPhone is

$P(I)=62\%$

and the probability that someone owns Apple watch is

$P(A)=15\%$

and the probability that someone owns both is

$P(I \cap \: A) = 8\%$
Since the intersection is not zero, it means the two events are not mutually exclusive.

The probability that someone owns an iPhone or Apple phone is

$P(I \cup \: A) = P(I) + P(A) - P(I \cap \: A)$

We substitute the values to get,

$P(I \cup \: A) = 62\% + 15\% - 8\%$

$P(I \cup \: A) = 69\%$
