Juanita has three straws that are 5 in. long and three straws that are 10 in. long. Name one combination of three straw lengths she can use to form a triangle and one combination that cannot form a triangle. Explain your thinking.
Answers
Answer:
A possible triangle:
5,5,5 or 10,10,10
5,10,10
An impossible triangle:
5,5,10
Step-by-step explanation:
An equilateral triangle is a triangle that has all three sides the same. If Juanita builds a triangle with 5,5,5 or 10,10,10 she will create an equilateral triangle.
The Triangle Inequality Theorem says that the sum of two sides of a triangle has to be bigger than the third side.
So 5,10,10 can also be a triangle because
5+10 > 10 or
10+10 > 5
What cannot happen is if two of the sides added together ***equals*** the third side. Those two sides would just lie flat on top of the third side and not make a triangle.
So if Juanita used 5,5,10 and 5+5=10 she cannot make a triangle from straws of those three sizes.
To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. One combination (5 in. + 5 in. + 5 in.) can form a triangle, and another combination (5 in. + 5 in. + 10 in.) cannot form a triangle.
To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. Let's consider the combinations of three straw lengths:
Combination 1: Three straws of length 5 in. each. Since 5 + 5 > 5, this combination can form a triangle.Combination 2: Two straws of length 5 in. each and one straw of length 10 in. Since 5 + 5 = 10, this combination cannot form a triangle.Learn more about Triangles here:https://brainly.com/question/34963952

Liz purchased three trays of tomato plants for $16.47. She also bought ten trays of basil plants. If the ratio of the price per tray of tomato plants to the price per tray of basil plants is 3 to 2, then how much did she spend in total for all the plants? Write and solve a proportion.
Please help! Tysm <3
Answers
Step-by-step explanation:
Start by creating expressions
t= A tray of tomato plants
3t = $16.47
Solve the equation above
3t/3= 16.47/3
t= 5.49
A tray of tomato plants costs $5.47
Now create the ratios
b= A tray of basil plants
t:b = 3:2
Substitute t
5.49:b = 3:2
Rewrite as fractions
\(\frac{5.49}{b}\) = \(\frac{3}{2}\)
Cross multiply
5.49(2) = 3(b)
10.98 = 3b
10.98/3 = 3b/3
3.66 = b
A tray of basil plants costs $3.66
In total she bought 3 trays of tomato plants, which cost $16.47, and 10 trays of basil plants
T0 find out the cost of the 10 basil plants, multiply 3.66 by 10
3.66 × 10 = 36.6
She bought 10 trays of basil plants for $36.60 and 3 trays of tomato plants for $16.47
Add the 2 values together
36.60+16.47 = 53.07
$53.07 is the total

what is the value of q?
Answers
Answer: q=70°
Step-by-step explanation: 52°+58°+q=180°
next q=180°-110°
so q=70°
52+58 gives you 110.
180 is the half of a full rotation, so the straight line is 180 degrees.
180-110 would give you 70 degrees.
When a number is decreased by 19%, the result is 66. What is the original number to the nearest tenth?
Answers
Answer:
80
step by step explanation:
when a number is decreased by 19 %, u calculate backwards, making the % to 119% of 66. Hence it becomes 78.54 to be exact, but in the nearest tenth, it becomes 80.
Answer:
81.48 (81.5 rounded)Step-by-step explanation:
from the question 66 is = 81%
(100% - 19% = 81)

Estimate the area of the circle. Use 3.14 or 22/7 for π.
explain pls and Thank you
Answers
Step-by-Step Explanation:
Diameter = 28 cm
Radius (r) = 28/2 = 14 cm
Area = πr^2
Therefore,
= πr^2
= π * r^2
= 22/7 * 14 * 14
= 22 * 2 * 14
= 616
Area = 616 cm^2
Because a=pi r^2 a=3.14 14^2 14 squared equals 196 and 196×3.14 equals 615.44

Step-by-step explanation:
1/500=0.002
3 2/25=308%
2.6=2 6/10
0.25%=0.0025
Answer:
They are actually in the correct order left to right !
Step-by-step explanation:
1/500 is 0.002 because 0.002 is pronounced "two thousandths" and 0.001 is pronounced "one thousandth", but it's written as 0.001 OR the fraction 1/1000! Using this you can infer that "two thousandths" is twice as large as 1/1000.
1/25 is 0.04, so 2/25 is 0.08 add the 3 and get 3.08. When displayed percentages in decimal form 100% = 1, so 300% = 3, therefore 308% = 3.08.
In the number 2.6 the decimal .6 is in the TENTHS place and so you can formally say this as "two and six tenths", which how the fraction 2 6/10 is also said!
As stated above when displaying percentages in decimal form:
100% = 1,
25% = 0.25,
1% = 0.01,
0.25% = 0.0025!
Consider the situations in the table below
Situation A: A hang glider descended 33.57 feet, and then ascended 14.98 feet.
Situation B: A football team gained 7 2/5 yards in one play, and then lost 3/5 of a yard in the next play.
Situation C: A hiker walked 3 1/6 miles yesterday and 2 1/2 miles today.
Situation D: A worker earned $23.66 Monday and spent $15.84 Tuesday.
Calculate the sum of each situation. Order the situations from least to greatest based on the numeric value of the sums.
Answers
Answer:
Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet
Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.
7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.
Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.
Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

If there are 2 red balls, 2 blue balls, and 4 green balls in a pail, what is the probability of pulling out a green ball?
(step-to-step pls)
Answers
Answer:
Step-by-step explanation:
Step 1 is to find the total number of balls in the pail.
There are 8 balls in total
Now that you know there are 8 balls, you have to find out how many of those 8 are green. This is because you want to pull out a green ball. You would do the same thing for any other colored ball.
Since 4 out of the 8 balls in the pail are green, you can write this as 4/8
The last step is to simplify to get 1/2 which in other terms is 50%.
So the probability of you pulling a green ball is 50%
