Answer:

C. 7

Step-by-step explanation:

Points J and K are midpoints of the sides of triangle FGH.

=> JK = 1/2FG

2y + 5 = 1/2(5y + 3)

4y + 10 = 5y + 3

5y - 4y = 10 - 3

y = 7

The value of y is 7 for the given triangle.

The properties of the triangle are: The sum of all the angles of a triangle (of all types) is equal to 180°. The sum of the length of the two sides of a triangle is greater than the length of the third side. In the same way, the difference between the two sides of a triangle is less than the length of the third side.

We know that GJ = JH, and HK = KF.

Also, J and K are midpoints of GH and HF, respectively.

Therefore, we can say that:

GJ + JH + HK + KF = GF

2(GJ + HK) = GF

2(2y + 5) = 5y + 3

4y + 10 = 5y + 3

y = 7

Therefore, the value of y is 7.

Step-by-step explanation:

A convex pentagon has interior angles that measure 60, 80, 120, and 140. What is the measure of the fifth interior angle?

Given -

To Find -

Solution -

Let us assume fifth interior angle as x

We know,

Sum of interior angles of a pentagon is 540°

60° + 80° + 120° + 140° + x° = 540°

→ 400° + x° = 540°

→ x° = 540° - 400°

→ x = 140°

Fifth interior angle of a pentagon = 140°

If the Thompsons need the movers for more than 6 hours, City movers would be the better deal. Therefore, option D is the correct answer.

Graph is a mathematical representation of a network and it describes the relationship between lines and points. A graph consists of some points and lines between them. The length of the lines and position of the points do not matter.

Given that, the Thompson family was moving and hired Town Movers to move them for a fee of $30 plus $15 per hour.

Let the number of hours be x.

Now, 30+15x

Movers called and offered a fee of $72 plus $8 an hour, which they thought might be a better deal

72+8x

From the graph, both the movers have same charge at 6th hour and City movers charge is decreasing then compare to Town Movers.

Therefore, option D is the correct answer.

Answer:

  (a)  135

  (b) 28%

Step-by-step explanation:

We can write equations relating pears to oranges, solve them, and then find the number of apples. Let p, o, and 'a' represent the numbers of pears, apples, and oranges.

  p/o = 5/3 . . . . . the ratio of pears to oranges is 5:3

  p -o = 54 . . . . . there are 54 more pears than oranges

  a -o = 3 . . . . . .  there are 3 more apples than oranges

__

Multiply the first equation by 3/5o to get ...

  3/5p = o

Substitute that into the second equation:

  p -(3/5)p = 54

  2/5p = 54 . . . . . . simplify

  p = 54(5/2) = 135 . . . . multiply by 5/2 to get the number of pears

There are 135 pears in the basket.

__

  a = 3 +o = 3 +3/5p = 3 +3/5(135) = 3 +81 . . . . solve for the number of apples

  a = 84

The percentage of fruits that are apples is ...

  apples/total = 84/(135 +81 +84) = 84/300 = 28/100 = 28%

  28% of the fruits are apples

Answer:

y = 6

Step-by-step explanation:

- x + 3y = 9 ( add x to both sides )

3y = 9 + x → (1)

y = [tex]\frac{2}{3}[/tex] x ( multiply both sides by 3 to clear the fraction )

3y = 2x → (2)

substitute 3y = 2x into (1)

2x = 9 + x ( subtract x from both sides )

x = 9

substitute x = 9 into (1)

3y = 9 + 9 = 18 ( divide both sides by 3 )

y = 6

Approximately 5.6 x 10¹⁴ grains of wheat in scientific notation.

A geometric series is a sequence of numbers in which each term is obtained by multiplying the previous term by a fixed constant. This constant is called the common ratio, and it is denoted by the letter "r".

The formula for the sum of the first n terms of a geometric series is:

S_n = a(1 - rⁿ)/(1 - r)

where S_n is the sum of the first n terms, a is the first term of the sequence, r is the common ratio, and n is the number of terms in the series.

The number of grains of wheat on each square of the board can be found by raising 2 to the power of the square number minus 1. For example, the number of grains of wheat on the first square is 2⁰ = 1, the number on the second square is 2¹ = 2, the number on the third square is 2² = 4, and so on.

So, the total number of grains of wheat on the board is the sum of 2⁰ + 2¹ + 2² + ... + 2⁴⁸. This is a geometric series with first term 1 and common ratio 2. Using the formula for the sum of a geometric series, the total number of grains of wheat is:

2⁰ + 2¹ + 2² + ... + 2⁴⁸ = (2⁴⁹ - 1)/(2 - 1) = 2⁴⁹ - 1

This is approximately 5.6 x 10¹⁴ grains of wheat in scientific notation.

The value of x for which this model will make the least sense to use is at x=-2.75 seconds.

A function assigns the value of each element of one set to the other specific element of another set.

The function that is given to us is h(x) = –16x²+100 where x is the time in seconds.

Now, use the function to know the height of the object, therefore, the height of the object can be written as,

Time, t₁=0

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0)=0+100\\\\h_1=100[/tex]

Thus, the height of the object when the time is 0 seconds is 100.

Time, t₂=0.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(0.5)=-4+100\\\\h_2=96[/tex]

Thus, the height of the object when the time is 0.5 seconds is 96.

Time, t₃=1

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1)=-16+100\\\\h_1=84[/tex]

Thus, the height of the object when the time is 1 second is 84.

Time, t₄=1.5

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(1.5)=-36+100\\\\h_4=64[/tex]

Thus, the height of the object when the time is 1.5 seconds is 64.

Time, t₅=2

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(2)=0+100\\\\h_5=36[/tex]

Thus, the height of the object when the time is 2 seconds is 36.

Now as we can see that the error in the height of the object can be a maximum of 1, therefore, for different values of x, the change in height will be,

Time, t₆= -2.75

Now, the height can be written as,

[tex]h(x) = -16x^2+100\\\\h(-2.75)=-121+100\\\\h_6= -21[/tex]

Thus, the height of the object when the time is -2.75 seconds is -21.

Hence, the value of x for which this model will make the least sense to use is at x=-2.75 seconds.

Hi! Hope you are having a nice day!

Yes, the square of a rational number is always positive.

We know that a negative times a negative equals a positive only.

Well, a negative squared also equals a positive.

For example, (-4)² is equal to 16.

Because

(-4)×(-4)=16

Hope you could understand everything.
