GEOMETRY. I will give brainliest
Answer:
15 (3rd option)
Step-by-step explanation:
Circumference formula=2 x pi x r(radius)
So, 30 pi = 2 pi r
Next, isolate the r(radius)
30 pi / 2 pi = r
The 2 pi's cancel out and leaves 30/2
r=15

Trigonometric Ratios
Find h.
Answer:
63
Step-by-step explanation:
use tangent formula
[tex] \tan(40) = \frac{h}{75} [/tex]
Answer:
h ≈ 62.9 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan40° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{h}{75}[/tex] ( multiply both sides by 75 )
75 × tan40° = h , then
h ≈ 62.9 ft ( to 1 dec. place )
Let R be the region enclosed by the y-axis, the line y=1 and the curve y=x^3. A solid is generated by rotating R about the line y=1. What is the volume of the solid
Answer:
The volume of the solid is 19.[tex]\overline{142857}[/tex] unit³
Step-by-step explanation:
The given function is y = x³
The solid is created by revolving R about the line y = 1
We have that when y = 1, x = 1
Taking the end point as x = 2, we have the volume given by the washer method as follows;
[tex]V = \pi \cdot \int\limits^a_b {\left( [f(x)]^2 - [g(x)]^2 \right)} \, dx[/tex]
Where;
a = 1, and b = 2, we have;
g(x) = 1
[tex]V = \pi \cdot \int\limits^{2}_1 {\left( [x^3]^2 - [1]^2 \right)} \, dx = \pi \cdot \left[\dfrac{x^7}{7} + x \right]_1^{2} = \pi \cdot \left[\dfrac{2^7}{7} +2 -\left( \dfrac{1^7}{7} + 1\right)\right] =19\dfrac{1}{7}[/tex]
The volume of the solid, V = [tex]19\dfrac{1}{7}[/tex] unit³ = 19.[tex]\overline{142857}[/tex] unit³

GEOMETRY:
Explain why segment PR is congruent to segment VE, given segment VO is congruent to segment RO and line PR is parallel to line VE
Answer:
See explanation
Step-by-step explanation:
∠POR is congruent to ∠VOE because they are vertical angles
∠PRV is congruent to ∠RVE because alternate interior angles are congruent when the lines are parallel.
VO is congruent to OR which is given
Therefore, ΔPRO is congruent to ΔEVO by the angle-side-angle theorem
So, PR is congruent to VE because corresponding parts of congruent triangles are congruent

Solve each problem. Explain or show your reasoning.
a. What is 25% of 160?
Answer:
40
Step-by-step explanation:
Hi there,
Before solving this problem, it is useful to know that 25% is equivalent to 1/4 or 0.25. There are two ways to solve this problem:
1.) Multiply 0.25 by 160
or
2.) Divide 160 by 4.
Either way, the answer is still 40. Hope this answer was useful. Cheers.
Which weighs more: a puppy that weighs 8.5 kilograms or a baby that weighs 11 pounds? Explain your reasoning.
Answer:
a baby weight more because the baby will grow and will weight more then a puppy
Step-by-step explanation:
Answer:
A puppy that weights 8.5 kilograms weighs more.
Step-by-step explanation:
A puppy that weights 8.5 kilograms weighs more. Why? Well if you convert the 11 pounds from the baby to kilograms it would equal about 5 kilograms. The puppy's weight in kilograms is 8.5 and its weight in pounds is 18.7, while the baby's weight in kilograms is 5 and it's weight in pounds is 11.
Puppy's Weight Kilograms: 8.5
Puppy's Weight Pounds 18.7
Baby's Weight Kilograms: 5
Baby's Weight Pounds: 11
Weight in Kilograms: Puppy: 8.5 > Baby: 5
Weight in Pounds: Puppy: 18.7 > Baby: 11
Therefore, the puppy is heavier.

Triangle QRS is a right triangle.
What is the lenghts of RS.
0 10
0 7.1
05.3
0 14
Answer:
5.3
Step-by-step explanation:
a² + b² =² c² the Pythagorean theorem
RQ² + RS² = QS² Solve RS
6² + RS² = 8²
RS² = 64 -36
RS² = 28
RS = √28 28 is slightly > 25 and since √25 =5
RS = 5.3 actually 5.2915 to a few more significant digits

Which property is represented below?
(7 * 3) * 8 = 8 * (7 * 3)
9514 1404 393
Answer:
commutative property
Step-by-step explanation:
The commutative property of multiplication lets you swap the order of the operands (7*3) and 8 to make them have the order 8 and (7*3).
Use y = 5x + 36 to find the value of x when y = 80.
Answer:
If y = 80 then 5x+36 also equals 80
80 - 36 = 44
therefore 5x = 44
44 / 5 = 8.8
x=8.8

4x+2y=8
x+y=4
Elimination method & graphing method!
MUST SHOW WORK!
Answer:
x = 0 and y = 4.
Step-by-step explanation:
The given equations are :
4x+2y=8 ...(1)
x+y=4 ...(2)
Multiply equation (2) by 2.
2x+2y=8 ...(3)
Subtract equation (3) from (1).
4x+2y-(2x+2y)=8-8
4x+2y-2x-2y=0
2x = 0
x = 0
Put the value of x in equation (2).
0+y=4
y = 4
So, the value of x and y are 0 and 4.

m + 2m + -4m = -5 What is m?
Answer:
m = 5
Step-by-step explanation:
Rewrite problem
m + 2m + -4m = -5
Combine like terms
-1m = -5
Divide -1 on both sides
-1m = -5/-1
m = 5
Check answer
5 + 2(5) +-4(5) = -5
5+ 10 + -20
-5 = -5

Use prime factorization to find the LCM and the HCF of 210 and 112
Answer:
HCF = 14
LCM = 1680
Step-by-step explanation:
Factorizing the given values
210 = 2 * 3 * 5 * 7
112 = 2 * 2 * 2 * 2 * 7
Since 2 * 7 is common to both factors
Hence the HCF = 2 * 7 = 14
For LCM, we we will multiply all the prime factors that are in both
LCM = 2* 2 * 2 * 2 * 3 * 5 * 7
LCM = 112 * 15
LCM = 1680
Hence the LCM is 1680

Answer:
0.87
Step-by-step explanation:
Out of a total number of 100 questions, Daniel is said to have answered 87.
We first express this as a fraction.
Total number of questions he answered divided by total number of quiz questions
= 87/100
As a decimal, 87 divided by 100 = 0.87.
You can easily get this by using the calculator.
Thank you!
