Answer:

1 foot

Step-by-step explanation:

1 yard = 3 ft

[tex]2*1 yard= 2*3feet[/tex]

2 yards = 6 feet

[tex]\frac{1}{6}[/tex] (2 yards) = [tex]\frac{1}{6}[/tex] (6 feet)

So, [tex]\frac{1}{6}[/tex] of 2 yards is 1 foot.

Answer:

D - 33

Step-by-step explanation:

From 5 to 6, the number is increasing by 1. Then from 6 to 8, it increases by 2. From 8 to 11 it increases by 3. This pattern continues throughout the entire sequence. Since between 20 and 26, it increases by 6, 26+7 should equal the number between 26 and 41. This number would be 33.

Answer:

Step-by-step explanation:

we have a right triangle,

to find out the hypotenuse, h

H^2=13^2+4^2

H^2=169+8=177

The required equation would be x² = 13² + 4² which is determined by Pythagoras theorem that is used to the length of the Ladder needed to reach the window.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

Pythagoras theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

We have given that the window is 13ft above the ground and the base of the ladder is 4ft from the building

As per the condition, We have a right triangle.

To find out the hypotenuse x

By Pythagoras theorem,

⇒ x² = 13² + 4²

⇒ x² = 169 + 8

Therefore, the equation would be x² = 13² + 4²which is used to determine the length of the Ladder needed to reach the window.

Hence, the correct answer would be an option (A).

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer:

4 yds

Step-by-step explanation:

So... 16 yards is 48 feet (because one yard is 3 feet so I just multiplied by 3)

and she cuts 9 pcs of ribbon each 4 feet

so it's 9 x 4 = 36

48 - 36 = 12

And 12 feet equals 4 yards

So, Joy has 4 yards of remaining ribbon

Step-by-step explanation:

Look at the picture below. Sorry if its hard to understand.

The results for the addition operation are obtained as  84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.

The arithmetic operations are the fundamentals of all mathematical operations. The example of these operators are addition, subtraction, multiplication and division.

The given problem can be solved as follows,

(a) 45²/₉ + 39³/₉

⇒ 45 + 2/9 + 39 + 3/9

⇒ (45 + 39) + (2/9 + 3/9)  = 84⁵/₉

(b) -24⁵/₉ + 30⁷/₉

⇒ -24 - 5/9 + 30  + 7/9

⇒ (-24 + 30) + (7/9 - 5/9)

⇒ 6²/₉

(c) 28.98 + (-52.22)

⇒ 28.98 - 52.22

⇒ -23.24

(d) 56.75 + 75.12

⇒ 131.87

The given arithmetic operation can be matched in the form of table as,

    Sum                                    Result

45²/₉ + 39³/₉                             84⁵/₉

-24⁵/₉ + 30⁷/₉                            6²/₉

28.98 + (-52.22)                     -23.24

56.75 + 75.12                           131.87  

Hence, the given numbers are added to give result as 84⁵/₉,  6²/₉,  -23.24 and 131.87 respectively.
