-Step-by-step explanation:

a) 82
b) 42
c) 98
d) 70

Answers

Answer:

option d.

let the two angle of mnp be x and y

in the trapezoid NO and MP are parallel.

so the 28° = y and 42°=x(by alternate interior angle)

so the angle mnp= x+y

angle mnp=28°+42°=70°

Walmart is selling 100 mL tubes of toothpaste for $1.79 or 150 mL of toothpaste for $2.19. Which is the better buy?

Answers

Answer:

1.79/100mL = 0.0179

2.19/150mL = 0.0146

so, look at the end numbers

0.0179

0.0146

0.0146 is less than 0.0179

soo, $2.19 / 150mL = 0.0146 is the better buy...

Answers

Answer:

3 = ?

Step-by-step explanation:

The triangles are similar, so we  can use ratios

15           12 -2

------   = --------------

15+?          12

15           10

------   = --------------

15+?          12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

My soccer team has 16 players. I have to choose a starting lineup of a goalie and 10 regular players (the regular players are interchangeable). How many different starting lineups can I choose?

Answers

Answer:

48048

Step-by-step explanation:

Total number of players = 16

Selection to be made :

1 goalie ; 10 players

Hence ;

Choosing 1 goalie from 16 players :

16C1

Choosing 10 players from the remaining (16 - 1), 15 players

15C10

Hence,

16C1 * 15C10

16 * 3003

= 48048

High-definition televisions have an aspect ratio of 16: 9. The following answer choices are television screen sizes rounded to the nearest inch. Which could be a High-definition television?

Answers

Answer:

18.5 in approx

Step-by-step explanation:

Given data

aspect ratio of 16: 9

L= 16in

W= 9 in

We want to find the diagonal of the TV

applying Pythagoras theorem

d^2= l^2+w^2

d^2= 16^2+ 9^2

d^2=256+81

d^2= 337

d= √337

d= 18.35 in

Hence the tv is 18.5 in approx

Answer: m∠5 = 75°.

Step-by-step explanation:

We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.

We know that:

"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"

Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)

Then the measure of ∠1 is the same as the measure of ∠5

And we know that m∠1 = 75°

Then we must have that m∠5 = 75°.
