First convert them to fractions (the answer choices are fractions):

a) 0.333... = 1/3
b) 0.555... = 5/9

Now add a and b:

1/3 (or 3/9 for a common denominator) + 5/9 = 8/9

That fraction is in simplest form, so leave it as it is.

Hope this helps!

kite is a quadrilateral with two pairs of adjacent, congruent sides. The vertex angles are those angles in between the pairs of

just olya [345]

If we have a kite ABCD where AB = CD and DC = CA.
Let E be a midpoint between BC
Since triangle ABC is an isosceles triangle, ray BE bisects angle ABC and is perpendicular to AC.
So, angle ABE = CBE.
<span>Since also triangle CDA is isosceles, line DE is perpendicular to AC for the same reason. Therefore, AC is perpendicular to BD.</span>

Please help me find x and y. Give a real answer that is correct.

Cerrena [4.2K]

Answers:

x = 5/2 = 2.5

y = 10

============================================

Explanation:

Focus on the smallest triangle and the medium sized triangle. We can form the proportion 2/4 = x/5 by dividing the corresponding sides together.

Solving for x leads us to the following

2/4 = x/5

2*5 = 4*x

10 = 4x

4x = 10

x = 10/4

x = 5/2

x = 2.5

-----------------

Now focus on the medium sized triangle and the largest triangle. We'll use the same idea as before

4/8 = 5/y

4y = 8*5

4y = 40

y = 40/4

y = 10

Note how each horizontal line is a midsegment, which means that jumping from y = 10 to 5 is us taking half of that value. Then going from 5 to x = 5/2 = 2.5 is another step of cutting in half.

What is the ratio of people who prefer oranges to bananas?

Vikki [24]

I saw the pie chart that should have accompanied this word problem.

Favorite fruit:
Grapes = 150
Apple = 220
Orange = 185
Banana = 235

Choices:
A) 37/47
B) 185/790
C) 790/275
D) 235/185

Oranges = 185 ; Bananas = 235

Ratio of oranges to Bananas = 185/235
Simplify 185/235
185 ÷ 5 = 37
235 ÷ 5 = 47

Ratio of oranges to Bananas = 37/47 Choice A.

Which expression is equivalent to 6(3+0.05)?

Gnesinka [82]

$\huge{\boxed{6(3)+6(0.05)}}$

The distributive property shows that you need to multiply the $6$ separately by each term in the parentheses. This means you multiply $6*3$ and $6*0.05$ , then add them together to get $6*3+6*0.05$ , or in the terms of your answer choices, $\boxed{6(3)+6(0.05)}$ .

Rewrite 9(10 x) in distributive property

Ierofanga [76]

9(10+x)

To apply the distributive property, we need to multiply the number out of the parenthesis by each number inside.

9*10 = 90
9*x = 9x

9x + 90

Final answer: 9x + 90
