Answers

Answer 1

Answer:

Answer:

D) 45

Step-by-step explanation:

When a line bisects an angle, it cuts the angle into two equal halves. This means that ABD and DBC have the same angle measure, which is half of 90 degrees or 90/2=45. Hope this helps!

Answers

Total distance walked by Layla is 300 yards

Solution:

Given that,

Layla is walking in a rectangular park

She walks one side that is 50 yards and then the other side that is 120 yards

Length = 120 yards

Width = 50 yards

Layla develops a cramp in her leg and walks diagonally through the park to head back home

Let us find the length of diagonal of rectangle

$d=√(w^2+l^2)$

$d = √(50^2+120^2)\n\nd = √(2500+14400)\n\nd = √(16900)\n\nd = 130$

Thus length of diagonal is 130 yards

What is the total distance that layla walked?

Given that Final answer is perimeter of the triangle park

The diagonal and length and width forms a right angle triangle

Perimeter of triangle = diagonal length + width + length

Perimeter of triangle = 130 + 50 + 120 = 300

Thus total distance walked by Layla is 300 yards

Which of these percentages is closest in value to 7/9 ?
a. 76%
b. 77%
c. 78%
d. 79%

Answers

$(7)/(9) = 0.777777777777777...$

To get a percentage, you need to first round the decimal to the hundreths place. Whenever you have a number greater than 5, you round up.
Therefore, you can round it to 0.78.
Now to get the percentage you multiply it by 100.

$0.78*100 = 78$

This shows your answer is (c) 78%.

$(7)/(9)$ ≈ $0.77777..$

$0.7777$ ≈ $0.78$

$0.78*100=78$ $\boxed{->C}$

The answer is 78%
