2y +3<11
What is the largest value of y could be?

Answers

Answer 1
the greatest value of y is 2y+3=11 => y=4
Answer 2

Answer:

Step-by-step explanation:

2y + 3<11                       Subtract 3 from both sides

2y < 11 - 3

2y < 8                           Divide by 2

2y/2 <8/2                  

y < 4

The question is very hard to answer. That's because the answer is very close to 4, but it is not 4.

For example 3.8 is a possible answer. Try it

2*3.8 + 3 < 11

7.6 + 3 < 11

10.6 < 11

But is that the largest value possible? No.

For example

y could be 3.99999999 Well maybe that could be the answer. No it isn't. Because, though very close to 11, it still cannot be 11. It might round to 11, but it does not equal 11.

I don't exactly know what you are expected to answer. I can only say that y cannot be 4, but it can be as close to 4 as you care to make it. If the question means what is the largest integer that y could be, then the answer is 3.

Pedro is building a playground in the shape of a right triangle. He wants to know the area of the playground to help him decide how much sand to buy. Compose the playground and a matching triangle into a rectangle. What are the dimensions of the​ rectangle? Find the area of the playground. A right triangle has a horizontal base of length 6 yards and a height of 3 and one third yards.

Answers

Answer:

Dimensions of rectangle:

Length =6 yards

Width=3 1/3 yards

Area of right triangle = 10 yd^2

Step-by-step explanation:

The right triangle has base as 6 yards and height as 3 1/3 of yards.

When we match this triangle with another right triangle to make  the rectangle is another right triangle with sides 6 yards and 3 1/3 yards.

Tia, Veronica, Pam, and Lily are sisters. Tia is 8 years old and she is 2 years older than Pam. Pam is 5 years younger than Veronica and Veronica is 4 years younger then Lily. Which list has the sisters in order from youngest to oldest?

Answers

Answer:

Pam 6

Tia 8

Veronica 11

Lily 15

Step-by-step explanation:

Tia's age = 8

Pam's age = Tia's age - 2

8 - 2 = 6

Veronica = pam's age + 5

6 + 5 = 11

Lily's age = veronica's age + 4

11 + 4 = 15

The diagonal of a suitcase measures 30 inches and the height is 18 inches. What is the width of the suitcase to the
nearest Inch?

Answers

Answer:

Step-by-step explanation:

By the Pythagorean Theorem we know

h^2=x^2+y^2 (where h is the hypotenuse and x and y are sides of a right triangle)

w^2+18^2=30^2

w^2=30^2-18^2

w^2=900-324

w^2=576

w=24 in

In the Pythagorean Theorem, a^2+b^2=c^2. The measurements provided here are 30, and 18. 30 is c and 18 is either a or b (it doesn’t matter) 30 is c because it is specified as a diagonal. In reverse to the Theorem, it would be 30^2-18^2= a^2 that would be 900-324. You would then square root what you got for “a” to find your answer. It would be 24.

Use π = 3.14 and round to the nearest hundredth of a meter.

Answers

Answer:

I believe the answer is 426.08 meters.

Step-by-step explanation:

To find the perimeter, break the shape into a rectangle and two semicircles. As two semicircles make one circle, you can do 72×3.14 to get 226.08. Then, add the length of the rectangle. 100+100=200. Finally, do 226.08+200 to get your answer.

Step-by-step explanation:

Let's simplify step-by-step.

2/5x + 5 − (1/5x − 3)

Distribute the Negative Sign:

= 2/5x + 5 + −1( 1/5x −3)

= 2/5x + 5 + −1 (1/5x) + (−1) (−3)

= 2/5x + 5 + −1/5x + 3

Combine Like Terms:

= 2/5x + 5 + −1/5x + 3 = (2/5x + −1/5x) + (5 + 3)

= 1/5x + 8

Answer:

y = -x

Step-by-step explanation:

m= (y2-y1)/(x2-x1)

m=(100-0)/( -100 -0)

m = 100/ -100

A tree is standing behind a building. 2/5th of the height of the tree can be seen and the rest is hidden by the building. The building is 12 metres high. What is the height of the tree?

If 2/5 of the tree can be seen the tree covers ( 1 - 2/5) 3/5 of the tree. If the  building is 12 metres high, it means that 2/5 of the building is 12m high

the height of the tree = 12 x (5/2) = 30m

2 sin^2 (x) + 3 sin (x) + 1 = 0
help me find the solution

Answers

Answer:

Step-by-step explanation:

\[2~ sin^2 x+3sin x+1=0\]

\[2sin^2x+2sin x+sin x+1=0\]

2sinx(sin x+1)+1(sin x+1)=0

(sin x+1)(2 sin x+1)=0

either sin x+1=0

sin x=-1=sin 3π/2=sin (2nπ+3π/2)

x=2nπ+3π/2,where n is an integer.

or 2sin x+1=0

sin x=-1/2=-sin π/6=sin (π+π/6),sin (2π-π/6)=sin (2nπ+7π/6),sin (2nπ+11π/6)

x=2nπ+7π/6,2nπ+11π/6,

where n is an integer.

A seagull is flying 11 meters above the water. Directly below the bird, a fish is swimming 31 meters under the surface. What is the total difference in distance between the bird and the fish? A 11 B 20 C 31 D 42

Answers

Answer: D. 42 meters

Step-by-step explanation:

In calculating the distance between the seagull and the fish, you need to add their distances from sea level as this shows their distance from the sea and then from each other:

Seagull is 11 meters above the water

Fish is 31 meters below the water

Total difference

= Fish + Seagull

= 31 + 11

= 42 meters
