Claire says that she can draw an obtuse equilateral triangle. Is she correct? Explain.

No, because an equilateral triangle is also equiangular so all sides must be 60° (60+60+60=180) and an obtuse angle is more than 90° so the triangle would not be equilateral.

Hope I Helped (:

No, she is not correct. an obtuse triangle is a triangle with angles equal to more than 90. An equilateral triangle has all triangle measures 60. since 60<90, Clarie is making a false statement

Select all that apply. To decide if 12.5 centimeters is greater than 140 millimeters, the first step is to set up a proportion.

Oksi-84 [34.3K]

Answer:

Hey there!

We can't compare two measurements without converting them to the same units. Thus, we use proportions to make all the values into the same unit.

$12.5 cm(\frac{10 milimeters}{1 centimeter})$ , which converts to centimetres to millimetres.

12.5 cm=125 mm.

Now, we can compare the values of 125 mm and 140 mm.

Clearly, we see that 140 mm is greater than 125 mm.

Let me know if this helps :)

At a family reunion, each of Sana aunts and uncles is getting photographed once, The aunts are taking pictures in groups of5 and

yaroslaw [1]

This question is based on least common multiple method.

As given in the question,

Aunts are taking pictures in group of = 5

Uncles are taking pictures in group of = 10

So we have been asked what is the minimum number of aunts Sana have.

As we have been given that the number of aunts and uncles is equal so to find the minimum number of aunts we will apply the least common multiple method.

So we get LCM of 5,10 as 10

Hence there are minimum 10 aunts.

A farmer estimates that he has 9,000 bees producing honey on his farm. The farmer becomes concerned when he realizes the populat

marysya [2.9K]

The answer to this question would be:
The function f(x) = 9,000(0.95)x represents the situation.
After 2 years, the farmer can estimate that there will be about 8,120 bees remaining.

In this problem, there are 9,000 bees and the amount is decreased 5% each year. Decreased 5% would be same as become (100%-5%=)95% each year. Then the function should be like:
f(x)= 9,000 * 95%^ x= 9,000 * 0.95^x

If you put X=2 and X=4 the result would be:
f(2) = 9,000* (0.95)^2= 8122.5 (round up to tenth will be 8120)
f(4) = 9,000* (0.95)^4= 7330.5
