Answer:
16
Step-by-step explanation:
An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 30 inches, and the length of the base is 10 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch.
The perimeter of the triangle is 70.82 inches.
Given as :
The length of the altitude is 30 inches, and
The length of the base is 10 inches
What is right triangle?Right triangle is defined as a triangle which one angle is a right angle or two sides are perpendicular.
Let, perpendicular = 30 and base = 5
According to Pythagoras theorem,
A right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
perpendicular² + base² = hypotenuse²
Substitute the values,
30² + 5² = hypotenuse²
900 + 25 = hypotenuse² or
hypotenuse² = 925
hypotenuse = √925
hypotenuse = 30.41
The perimeter of the triangle can be determined as:
Perimeter of the triangle = l₁ + l₂ + l₃
Perimeter of the triangle = 30.41+ 10 + 30.41
Perimeter of the triangle = 70.82
Hence, the perimeter of the triangle is 70.82 inches.

Answer:
47=7×5+4×3
Step-by-step explanation:
7×5=35 and then 4×3=12. 35+12=47
Answer:
? = 47/11
Step-by-step explanation:
47 = 7 x ? + 4 x ? (collect like terms)
47 = 11? (divide both sides by 11 to isolate for ?)
47/11 = ?
A tree in Kevin's backyard is 5/8 meters tall. It has been growing for 1 2/5 years. What is the unit rate in meters per year? No links.
Thank you.
Answer:
o.4464287142 or 0.4
Step-by-step explanation:
The tree is 5/8 meters tall and that's in 1 2/5 years so you would divide them and you get .4464287142
add 223+374+402 using expanded form
next,change your answer back too standard form
the answer is 999

The Area is 63.585
Step-by-step explanation:
So the diameter is twice the size of the "r" or radius so divide 9 by 2
which is 4.5
The formula for a circle is πr^2
4.5 times itself is 20.25
times pi or 3.14 is 63.585

Hello! answer: 105
Step-by-step explanation:
You can find the area separately then add it up so... 10 × 6 = 60 10 × 9 = 90 90 ÷ 2 = 45
60 + 45 = 105 therefore the area is 105
Answer:
105 square meters
Step-by-step explanation:
Area= a + b/2 • h
Area= 15 + 6/2 • 10
Area= 21/2 • 10
Area= 10.5 • 10
Area= 105

Chandra had scores of 100, 70, and 85 on three of her five tests. She cannot remember her two other scores, which were both the same. She does remember that the mean of the five scores is 75. Which statement below explains how to find the two missing scores?
Add the sum of the three test scores to the product of 75 and 5.
Subtract the sum of the three test scores from the product of 75 and 5.
Add the sum of the three test scores to the product of 75 and 5, and then double the result.
Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.
Answer:
Subtract the sum of the three test scores from the product of 75 and 5, and then divide the result by 2.
Step-by-step explanation:
From the question:
100, 70, 85 on three of her five tests
Total number of test = 5
mean of the five scores is 75
mean = average of the five scores
Average score = Total score / total number of test
Total score = Average score * total number of test
= 75*5 =375
to find remaining two tests' scores
Total score - the 3 scores from question
= 375 - 100 - 70 - 85
=120
If u want to find the score of each of the unknown test
From question:
She could not remember the other two scores, which were the same.
Thus,
The score of one test
= 120/ 2
=60

Answer: A
Step-by-step explanation:
A linear function is described as:
https://tex.z-dn.net/?f=f(x)%20%3D%20ax%20%2B%20b
When the value of x = 0, then you're left with
https://tex.z-dn.net/?f=f(x)%20%3D%20b
In this question, the speed of sound is the linear function while the temperature is the independent variable. When T = 0, you're left with
https://tex.z-dn.net/?f=S(0)%20%3D%20331.4
Which means the speed of sound in air when temperature is 0°C is 331.4m/s.

The line plot shows the ages of participants in two group activities at a science center.
What conclusion can be drawn about the data sets?
More 14- and 15-year olds are in group 2 than in group 1.
Group 1 participants have a greater range in age than group 2 participants.
The median age of participants in group 2 is older than the median age of participants for group 1.
The mean age of participants in group 2 is younger than the mean age of participants in group 1.
