I need help on how to do these my teacher didn’t explain it to me

Answers

Answer 1

a is 66 b is 100 c is 128 i believe

Answer 2

Answer:

Step-by-step explanation:

on the first one we see that they are outer angles and they are also congruent making the missing angle the same as 66

for the second one if we turn the graph around making the lines how a H shape we see the missing angle and the given angle are in the same line, and we know a straight line makes it 180, so we need to find what the other angle is using the given angle so we subtract from 180, 180-80 = 100

so the missing angle is 100 making it congruent to the other missing angle that was with the 80

for the last one by now we should know what vertical angles are, they are directly across from each other, and we see that they arent really like in the same part of the line, but we know that the one congruent to the 128 is the outer right angle, making the missing angle congruent because they are vertical angles making the missing angle 128 too

(did that make sense?)

Find the value of 3^sqrt(100)

Answer: 59049 or 4.64

Step-by-step explanation: 59049 is the answer to 3^sqrt(100), but I wasn't totally sure if you meant ^3sqrt(100) or not so I solved both.

3^sqrt(100) = 59048

^3sqrt(100) = 4.64158

Find the value of x.

Answers

Answer:

Step-by-step explanation:

All angles on a triangle equal 180. 80+60=140.

Now to solve for x, we set it to equal 40 for 180-140.

40=3x+7. 40-7=33

33=3x 33/3=11

x=11

Every triangle has to add up to 180 degrees. So if you already have 140 degrees, that’s what the 3x+7 has to add up to.

What is the answer to this?

Answers

Answer:

Y = 28.31

Z = 13.29

Angle A = 28

Step-by-step explanation:

For Angle A:

Remember a triangle has a total of 180 degree angles. So set up your formula as

180 - 62 -90 = Angle A

For Y:

The sine of an angle is equal to the ratio of the opposite side to the hypotenuse.

sin (B) = opp/hyp or b/c or (y)

sinB = 62

b = 25

Rewrite as c=b/2SinB -> c=25/sin62 -> Y = 28.31

For Z:

Use the Pythagorean theorem to find the unknown side.

[tex]z^{2} = 28.31^{2} - 25^{2}[/tex]

z = 13.29

Step-by-step explanation:

Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?

Answers

Answer:

96 tiles

Step-by-step explanation:

The kitchen floor is rectangular on shape.

The dimensions of the kitchen floor were 8 feet by 12 feet.

Hence, Area of a rectangle = Length × Width

Length = 8ft

Width = 12ft

Hence:

Area = 8ft × 12ft

= 96 ft²

If each tile was 1 square foot, the number of tiles he would need is

1 ft² = 1 tile

96 ft² = x

Cross Multiply

1ft² × x = 96 ft² × 1 tile

x = 96 ft² × 1 tile/1 ft²

x = 96 tiles

Therefore, Mark's father would need 96 tiles

you have a bucket that contains 3 red baseballs , 4 white baseballs, and 5 green baseballs. you are going to pick out one baseball, leave it out, and then pick another baseball. what is the probability of picking out a white baseball followed by a green baseball?

Answers

Answer:

probably a 60%

Step-by-step explanation:

Answer:

5/44

Step-by-step explanation:

3 plus 4 plus 5 is 12 so for a white it is 4/12 or 1/3

then you take out the white baseball and you want a green which is 5/11 3 red 3 white 5 green

5/11 times 1/3 is 5/33

so the odds of picking both is 5/33

Answers

Answer:

Step-by-step explanation:

Perimeter= all sides added together

so in this case

3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2

now you may be wondering why i put two 2x's, two 2+x, and two x-1 , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 ) so you need to account for all sides.

so lets simplify this huge equation!

3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2

3x+1 = 8x - 1 + 2 - 1 + 2

3x + 1 = 8x + 2

-3x on both sides

1 = 5x + 2

-2 on each side

-1 = 5x

A food production company is choosing between two suppliers of grain. Supplier A sells grain for $5.25 per bushel plus
a
delivery fee of $3 per bushel. Supplier B sells the grain for $6.50 per bushel plus a flat delivery fee of $1,500 each week.
Which supplier would cost more if the production company bought 500 bushels of grain each week?

Answers

Answer:

Supplier A: 5.25 per bushel and deliver fee of 3 per bushel

Supplier B: 6.50 per busher and flat delivery fee of $1500 each week

500 bushels of grain each week.

Supplier A: 5.25x + 3x = 5.25(500) + 3(500) = 2,625 + 1,500 = 4,125

Supplier B: 6.50x + 1500 = 6.50(500) + 1500 = 3,250 + 1,500 = 4,750

Supplier B would cost more if the company buys 500 bushels of grain per week.
