Answer:
14
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.

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
Hope this helps!

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 ?)

Evaluate the expression.
Answer:
131
Step-by-step explanation:
1. Do the brackets first because BEDMAS -> 5^2+2 x 53
2. Do the exponents -> 25 + 2 x 53
3. Multiply and divide (left to right) -> 25 + 2 x 53 -> 25 + 106
4. Add and subtract that -> 131

Avi's pet hamster Chubby loves to run in his hamster wheel. During one "race", Avi counts 1000 rotations of the wheel. She wants to know how far Chubby ran, so she measures the diameter of the wheel and finds that it is 20 cm. How far did Chubby run
Answer:
i think its 200 m
Step-by-step explanation:
because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km

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.
Two line plots one above the other, both are labeled from ten to twenty five by ones. The top line plot is labeled Age of participants dash group one and it has five Xs above fifteen, four Xs above fourteen, two Xs above thirteen, sixteen, and nineteen and one X above ten, twelve, seventeen, eighteen, and twenty. The bottom line plot is labeled Age of participants dash group two and it has four Xs above seventeen, three Xs above eighteen, two Xs above eleven, fifteen and sixteen and one X above twelve, thirteen, fourteen, ninteen, twenty, twenty three, and twenty five.

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

Alright man...
For question 1, angle ABC and angle CBD combines to form angle ABD. Just saying, question 2 literally answers question 1.
For question 2, it's literally addition. So 40 + 25 = 65°.
For question 3, it's just subtraction. 70 - 45 = 25°.
Good luck on ur test or whatever ur doing
