WILL CHOOSE BRAINLIEST!!! The oxford square is approximately 300 feet on each side. What is the length of the diagonal square?

Answers

Answer:

424 ft and 3 inches

Step-by-step explanation:

To calculate the diagonal of a square, multiply the length of the side by the square root of 2 --> d = a√2

a² + a² = diagonal²

diagonal = √(a² + a²) = √(2 x a²) which simplifies to diagonal = a√2

If area is given --> d = √(2*area)

Knowing square perimeter --> d = (perimeter/4)*√2

Given m\parallel nm∥n, find the value of x and y.

Answers

Answer:

See below ↓↓

Step-by-step explanation:

Finding x

Both the angles containing the x variable are on the same side of the transversalThere is a property which states that : two angles on the same side of the transversal are supplementaryTherefore, they add up to 180°⇒ 8x + 12 + 2x + 18 = 180⇒ 10x + 30 = 180⇒ 10x = 150⇒ x = 15

Finding y

The angles at the top are vertically opposite angles (VOA), meaning that they are equal⇒ 8x + 12 = 3y - 18⇒ 3y = 8(15) + 12 + 18⇒ 3y = 120 + 30⇒ 3y = 150⇒ y = 50

Answer:

(c) Write an equation to find the fraction of Jada’s garden that is made up of beefsteak tomatoes.
Answer:

Answers

Answer:

8/15

Step-by-step explanation:

The problem states that Jada has a vegetable garden made up of 2/3 tomato plants, of which 4/5 are beefsteak tomatoes. Therefore, to determine the portion of the garden that is made up of beefsteak tomatoes, both fractions must be unified in the same common divisor.

Thus, since the common least multiple of 3 and 5 is 15 (3 x 5), the fraction 2/3 can be calculated as 10/15. In turn, of those 10, 4/5 are beefsteak tomatoes, which can be calculated as 8/10, since the common lower multiple of 5 and 10 is exactly 10.

Therefore, 8/15 of Jada's vegetable garden are beefsteak tomatoes.

How to I solve this Area Problem for 7th grade?

Answers

Answer:

A. The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

Step-by-step explanation:

Area of Circle Pan: A = 3.14 * r^2

(3.14 will be used for Pi)

A = 3.14 * 5^2

A = 3.14 * 25

A = 78.5

Area of Rectangle Pan: A = l * w

A = 10 * 7

A = 70

Difference of the Areas (to compare them)

78.5 - 70 = 8.5

A. The area of the bottom of the round pan is greater than the area of the bottom of the rectangular pan by about 8.5 square inches

No, because 2 squared is 4. 2 squared times 2 squared is really 4 x 4, which is 16. The side length is 4 because the formula for area of a sqaure is length x width (4 x 4 = 16) or one side squared (4 squared which is 16).

hope this helped!

yes. The exponent represents how many times that number repeats. This explains that 2^2 (2 squared) is equal to 4. Which using basic knowledge, is 4•4= 16. And also, 2•2•2•2= 16. So yes, it is correct!

I buy a bed which normally costs £270 on a scheme where the price of the bed is increased by 60% but I only pay back £18 a month.

Answer:

it would take 2 years or 24 months

Step-by-step explanation:

60 percent of 270 is 162 add that to 270 and you get 432 divide that by 18 because that's what you're paying every month and you get 24 which is the numbe rof months it will take you to pay the bed off.

To cross check we can multiply 18 and 24 and you get 432.

Answer:

=432

Step-by-step explanation:

270-60%=162

162+270=432

432÷18=24

What is Linear Pair?

A linear pair is a pair of adjacent angles formed when two lines intersect. The two angles of a linear pair are always supplementary, which means their measures add up to 180 degrees.

A linear pair's sum of two angles is always 180°.All neighbouring angles are linear pairs, however not all adjacent angles are linear pairs.A linear pair of angles has a shared vertex and an arm in common.They are always in a straight line.

Given:

We have angles forms line are x, 120 and x.

So, x+ 120 + x = 180 (Linear pair)

2x+ 120 = 180

Now, Simplifying for x

Subtract 120 from both side we get

2x+ 120 - 120 = 180 - 120

2x = 60

Now, Divide both side by 2 we get

2x/ 2 = 60/ 2

x = 30

So, the measure of x is 30.
