Find the value of each variable. Round to the nearest tenth. How does the measure of angle x compare to the measure of angle z? Justify.
Answers
Answer:
z = 47.2°
w = 42.8°
y = 42.8°
x = 47.2°
Step-by-step explanation:
found altitude ('h') first: 6/h = h/7; h = [tex]\sqrt{42}[/tex]
found base by using Pythagorean Theorem:
7² + ([tex]\sqrt{42}[/tex])² = c²
c = [tex]\sqrt{91}[/tex]
found angle z using Rule of Sines:
sin 90 / [tex]\sqrt{91}[/tex] = sin z / 7
arcsin z = 7 / [tex]\sqrt{91}[/tex] = 47.2°
found angle w by adding 90 and 47.2, then subtracting from 180 to get 42.8°
found angle y by subtracting m∡z from 90° to get 42.8°
found angle x by adding 90 and 42.8°, then subtracting from 180

Answers
Answer:
volume of Sphere B is 8 times greater than the volume of Sphere A
Step-by-step explanation:
Sphere A: V = 4π (2^3)/3 = 32π/3
Sphere B: V = 4π (4^3)/3 = 4π(64)/3 = 256π/3
volume of Sphere B / volume of Sphere A = (256π/3)/(32π/3) = 8

In cm, the lengths of the sides of a rectangle are 30 and 24. Find the nearest degree the measure of the angle formed by a diagnol and one of the longer sides
Answers
Answer:
38.42cm
Step-by-step explanation:
Given that the length of the sides of a rectangle are 30 cm and 24 cm.
The length of the diagonal can be obtiaed using Pythagoras rule
Length of the diagonal = hypotenus
Hypotenus = sqrt(opposite ² + adjacent ²)
Opposite and adjacent sides are 30cm and 24 cm
Hypotenus = sqrt(30² + 24²)
Hypotenus = sqrt(900 + 576)
Hypotenus = sqrt(1476)
Hypotenus = 38.419
Length of diagonal = 38.42cm
Answer:
find the size of angle O to the nearest degree

32 km 24 km What is the length of the hypotenuse? C = kilometers
Answers
Answer:
40 kilometers
Step-by-step explanation:
the hypotenuse is a² + b² = c²
so first we have to get 32 and 24 into ²
32² = 1024 (32 × 32)
24² = 576 (24 × 24)
1024 + 576 = 1600
now we need to find the square root of 1600
√1600 = 40 (calculator)
therefore, the hypotenuse is 40 kilometers

Which set contains all the numbers in the list?
A integers
B whole numbers
C natural numbers
D rational number
Answers
Answer:
D. Rational Number
Step-by-step explanation:
Integers are defined as all whole numbers, positive and negative, including 0. Since in the list there is a number that is not whole, A is not the correct answer choice.Whole numbers are all positive numbers (including 0) without decimals or fractions. Since the list has a number that is not a whole number, along with two that are negative, B is also not correct.Natural numbers are all positive numbers (excluding 0) without decimals or fractions. Since there is a 0 in the list, C is not correct.Rational numbers are all numbers that can be simplified into a ratio with 2 integers (i.e. π and e are not rational). Since every number on the list can be put into this category, answer choice D is correct.Ryan is riding his bike. He biked a distance of 12 miles at a rate of 4 miles per hour.

The area of a right triangle is 3gh. Find the height if the base is 3gh.
Area of a triangle: A = 1/2bh
Answers
Answer: height is 2
Step-by-step explanation:
A = 1/2bh
A = 3; b (base) = 3. Substitute these values in the formula and solve.
3 = 1/2*3*h = 3/2 h
h = 3 * (2/3) = 2
Answer:
Height = 2
Step-by-Step Explanation:
So, I'm not sure if "gh" is a measurement. But I'm thinking it should be solved like this.
Area = 3gh
Base = 3gh
Height = ?
Plug & Chug
3gh = 1/2 (3gh)(h)
2/1 · 3gh = 1/2 (3gh)(h) · 2/1
[tex]\frac{(2)(3gh)}{(3gh)\\}[/tex] = [tex]\frac{(3gh)(h)}{(3gh)}[/tex]
h = [tex]\frac{(2)(3gh)}{(3gh)}[/tex]
h = 2
