What Is The Area Of KDL To The Nearest Tenth Of A Square Inch? Use Special Right Triangles To Help Find

Answers

Answer 1

Answer:

8

Step-by-step explanation:

This is a 45-45 traingle which mean that the two sides that aren't the hyptonouse are equal (because their angles are equal)

We will let x equal the length of one of the sides

we have

x²+x²=(4√2)²

2x²=32

x²=16

x=4

this means that the length of the two missing sides are 4

Now using the area of a traingle formula we can solve for the area

A=.5*b*h

.5*4*4=8

.5*4*4

Answer:

x = 42.5

Step-by-step explanation:

A triangle formed inside of a circle using the diameter as one of its side lengths is a right triangle

The right angle would be the angle opposite of the diameter (∠C)

A right angle has a measure of 90°

That being said we use this equation to solve for x

90 = 2x + 5

step 1 subtract 5 from each side

90 - 5 = 85

5 - 5 cancels out

now we have 85 = 2x

step 2 divide each side by 2

85/2=42.5

2x/2=x

we're left with x = 42.5

Which equation represents a line that passes through the points (4, 5) and (6, 9)? A. y = 2x-3 B. y - 3x-7 C. y= x + 3 D. y- + x + 7​

Answers

Answer:

A) y=2x-3

Step-by-step explanation:

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

m=(9-5)/(6-4)

m=4/2

m=2

y-y1=m(x-x1)

y-5=2(x-4)

y=2x-8+5

y=2x-3

Cheese sticks that were previously priced at "10 for $1" are now "4 for $1". Find each percent change

Answers

Answer:

The price per cheese stick was increased by 150%.

The amount of cheese sticks per $1.00 has decreased by 60%.

Step-by-step explanation:

The price per cheese stick was $0.10

1.00 (dollar) divided into 10 (cheese sticks) gives you 0.1, which means each cheese stick costs $0.10

The current price per cheese stick is $0.25

1.00 (dollar) divided into 4 (cheese sticks) gives you 0.25, which means each cheese stick costs $0.25

That means the price per cheese stick was raised by 150%.

That also means the amount of cheese sticks you could buy for $1.00 has decreased by 60%.

Answer:

28in, 195in, 197in

Step-by-step explanation:

There's no "supereasy" way to solve it, except by computation or approximation.

e.g. 2 3 6 couldn't work, because 2+3 < 6 so it's not even a triangle

125^2 cannot equal 122^2 + 30^2, because 125^2 is odd and 122^2 and 30^2 are even

23^2 + 18^2 = 529 + 324 < 900 < 31^2

So it has to be the last one, and after verification we find it checks out and 28^2 + 195^2 = 197^2

Jennifer's grandma bought her a $50 savings bond when she was born. When Jennifer is 30 years old, the bond will have earned 110% in interest. How much will the bond be worth when Jennifer is 30 years old?​

Answers

Answer:

105$

Step-by-step explanation:

We are told that she starts with 50$

We are also that after 30 years she earns 110% on interest

Given this information we need to find the value of the bond after the 30 years

To do so we take 110% of the initial value (50$) and add that to the initial value

So the answer = 110%(50) + 50

110%*50=55

55+50=105

So in 30 years the bond will be worth 105$

what is 2 3/4 as an improper factor..? just asking

Answers

Answer:

11/4

Hope this helps

Answer:

11/4

Step-by-step explanation:

An improper factor is a fraction that has a higher numerator (number in top) than the denominator (number in the bottom). Some examples of improper factors are 9/8 or 5/3 bc the top number is higher than the bottom one.

You can get the answer by multiplying 2 × 4 bc we want to know how many fourths (1/4) are in 2. In this case there are 8

then we add 8/4 with 3/4 to get 11/4
