and a who are tall but not slim or bald.
Find the number of men questioned who have
all three characteristics
b) work out the number who are bald but
not tall a silm.

Answers

Answer 1

Answer:

We have

n[T]=4+20-x+x+23-x

32=47-x

x=47-32

x=15

the number of men questioned who have

the number of men questioned who haveall three characteristics is 15.

again

n[S]=6+20-x+x+24-x=50-x=50-15=35

again

we have

n[U]=n[T]+n[s]+N only [ B]

54=32+35+N only [ B]-n[T and S]

N only [ B]=54-67+20=7

who are bald but

who are bald butnot tall a slim is 7.

Angle A is circumscribed about circle O.
What is the measure of angle O?

[picture below]

Answers

Answer:

134°

Step-by-step explanation:

[tex] In\: \odot O,[/tex] AB and AC are tangents at points B and C respectively. OB and OC are radii.

[tex] \therefore OB\perp AB\: \&\: OC\perp AC[/tex]

(By tangent radius theorem)

[tex] \therefore m\angle ABO =m\angle ACO = 90\degree [/tex]

[tex] m\angle CAB+ m\angle ABO +m\angle ACO+ m\angle BOC = 360\degree [/tex]

[tex]\therefore 46\degree + 90\degree +90\degree+ m\angle BOC = 360\degree [/tex]

[tex]\therefore 226\degree + m\angle BOC = 360\degree [/tex]

[tex]\therefore m\angle BOC = 360\degree-226\degree [/tex]

[tex]\therefore m\angle BOC = 134\degree [/tex]

[tex]\implies m\angle O= 134\degree [/tex]

What do the arrows heads indicate?

Answers

An arrowhead or point is the usually sharpened and hardened tip of an arrow, which contributes a majority of the projectile mass and is responsible for impacting and penetrating a target, as well as to fulfill some special purposes such as signaling.

Answer:

These pictures that you draw with arrows and arrowheads are representations of abstract mathematical objects. A ray is a subset of a line that has a starting point and extends indefinitely in one direction (not the other). The arrowhead is meant to indicate that it goes on and on.May 9, 2015

One angle of a parallelogram measures 60°. What are the measures of the other three angles in the parallelogram?

List answers from lowest to highest.

Answers

Answer:

60 degrees

120 degrees

Step-by-step explanation:

A parallelogram is quadrilateral that has two pairs of parallel sides. The opposite sides equal in length

Area = base x height

Sum of angels in a parallelogram is 360 degrees. Opposite angles are equal

If one angle measures 60 degree, the opposite angle would measure 60 degree

Angles remaining = 360 - 60 - 60 = 240

since opposite angles would be equal, each angle = 240 / 2 = 120

by selling an item at $20.70, a trader makes a profit of 15%. at what price should he sell the item so as to make a profit of 35%

Answers

Answer:

24.3 i think

Step-by-step explanation:

x * 1.15=20.7

20.7/1.15=18

18 * 1.35=24.3

$24.30

If something is sold at a profit of 15%, we write that percentage as 0.15. When we’ve added that to the whole amount we got the percentage from, we wrote that as 1.15 (115%)

If x is the cost of the item
1.15x = 20.70
Divide both sides by 1.15
x = 18

If the item originally cost 18, and we want a 35% profit, that’s 135% of the cost, or 1.35 as a decimal
18 x 1.35 = $24.30

Which statement best describes the angles of a rectangle ?
A) Each angle is 90 degrees
B) The two base angles are different angle measures
C) The sum of all the angles add up to 180 degrees
D) Each angle has a different measure

Answers

Answer: A

Step-by-step explanation:

We use process of elimination.

A rectangle has all right angles so A is a possibility.

The two base angles of a rectangle are NOT different angle measures so B is out of the question.

The sum of all the angles (90+90+90+90) is 360, not 180, so C is wrong.

All the angles of a rectangle are the same, so D is incorrect.

That means that A has to be correct!
