The length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The arc subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm.
As we know, the relationship between radius of the circle, central angle, and arc length is:
s = rθ
r = 7 cm
θ = 5.4 radians.
When two lines or rays converge at the same point, the measurement between them is called an "Angle."
s = 7×5.4
s = 37.8 cm
Thus, the length, to 1 decimal place, of the arc that subtends an angle of 5.4 radians at the center of a circle with a radius of 7 cm is 37.8 cm.

The number of cubic blocks, each with a volume of 1/36 cubic units, needed to fill the rectangular prism is a. 7 b. 19 c. 133 d. 152. ?
Answer:
The height of the prism is [tex]1\frac{1}{6}[/tex] units ⇒ answer a
The number of blocks needed is 133 ⇒ answer c
Step-by-step explanation:
* Lets explain how to solve the problem
- The volume of a rectangular prism is
→ V = Area of the base × its height
- The volume of the rectangular prism is [tex]3\frac{25}{36}[/tex] units³
- The area of its base is [tex]3\frac{1}{6}[/tex] units²
- Substitute the values of the volume and area of the base in the rule
∴ [tex]3\frac{25}{36}=3\frac{1}{6}*h[/tex]
- Divide the two sides by [tex]3\frac{1}{6}[/tex]
∴ [tex]h=\frac{7}{6}=1\frac{1}{6}[/tex] units
* The height of the prism is [tex]1\frac{1}{6}[/tex] units
- The volume of each cubic block is [tex]\frac{1}{36}[/tex] units³
- The number of blocks = volume of the prism ÷ volume of the block
∵ The volume of the prism is [tex]3\frac{25}{36}[/tex] units³
∵ The volume of each block is [tex]\frac{1}{36}[/tex] units³
∴ The number of blocks = [tex]3\frac{25}{36}[/tex] ÷ [tex]\frac{1}{36}=133[/tex]
∴ The number of blocks = 133
* The number of blocks needed is 133

HELPPPPPPP Consider the equation 3/4 y = 2.4x. Solve the equation for y. What is the constant of proportionality?
1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y
To solve the equation 3/4 y = 2.4x for y, we multiply both sides of the equation by 4/3 to eliminate the fraction. Simplifying the equation gives us y = 3.2x. The constant of proportionality in this equation is 3.2.
Explanation:To solve the equation 3/4 y = 2.4x for y, we need to isolate y on one side of the equation. First, we can multiply both sides of the equation by 4/3 to eliminate the fraction:
3/4 * y = 2.4x
y = (2.4x)/(3/4)
Next, we can simplify the equation by multiplying the numerator and denominator of the fraction by the reciprocal of 3/4, which is 4/3:
y = (2.4x) * (4/3)
y = (9.6x)/3
y = 3.2x
Therefore, the equation 3/4 y = 2.4x can be solved for y to give the expression y = 3.2x. The constant of proportionality in this equation is 3.2, which indicates that y is directly proportional to x with a scale factor of 3.2.

The measure of angle EYL is [tex]45\°[/tex]
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs which comprises
Let
x-----> the measure of arc EVL
y----> the measure of arc EHL
[tex]m<EYL=\frac{1}{2}(x-y)[/tex]
[tex]m<EYL=\frac{1}{3}(y)[/tex]
so
[tex]\frac{1}{3}y=\frac{1}{2}(x-y)[/tex]
Multiply by 6 both sides

[tex]y=(360\°)*(3)/8=135\°[/tex]
Find the value of x
[tex]x=\frac{5}{3}(135\°)=225\°[/tex]
Find the measure of angle EYL
[tex]m<EYL=\frac{1}{2}(x-y)[/tex]

[tex]m<EYL=\frac{1}{2}(225\°-135\°)=45\°[/tex]
In a game a die numbered 9 through 14 is rolled. What is the probability that the value of a roll will be a multiple of two or ten?
Answer:
Step-by-step explanation:
This is a special die. Its six sides bear the numbers {9, 10, 11, 12, 13, 14}.
There are three possibilities for getting a multiple of two: {10, 12, 14}, and
there is only one possibilities for getting a multiple of ten: {10, 12, 14}
The probability here of getting a multiple of two is 3/6, and that of getting a multiple of ten is 1/6. But one of the outcomes is found in both result sets: 10. Getting a multiple of 10 is already included in the event that the outcome is a multiple of two. My answer here would be 3/6, or 1/2.
the probability of rolling a multiple of two or ten is 4/6, which simplifies to 2/3.
The probability of rolling a multiple of two or ten on a die numbered 9 through 14 can be calculated as follows:
Numbers that are multiples of two in the given range are 10, 12, and 14, which are 3 possibilities.Numbers that are multiples of ten in the given range are 10, which is 1 possibility.Therefore, the total favorable outcomes are 3 (for multiples of two) + 1 (for a multiple of ten) = 4. The total possible outcomes from 9 through 14 are 6.Hence, the probability of rolling a multiple of two or ten is 4/6, which simplifies to 2/3.\
A trebuchet launches a projectile from a hilltop 30 feet above ground level on a parabolic arc at a velocity of 40 feet per second. The equation h = ?16t2 + 40t + 30 models the projectile's h height at t seconds. How long will it take for the projectile to hit its target on the ground? (to the nearest tenth of a second)
Answer:
t = 3.1 seconds
Step-by-step explanation:
Set the equation h = -16t^2 + 40t + 30 equal to 0 (0 represents ground level).
Then h = -16t^2 + 40t + 30 = 0
Applying the quadratic formula with a = -16, b = 40 and c = 30,
-40 ± √( 1600 - 4[-16][30] )
t = -----------------------------------------
2(-16)
-40 ± √ 3520
t = -------------------------
-32
-40 - 59.33
Only the positive t value makes sense. It is t = ------------------

Answer:
Price per foot of skydive is 31.11 repeated, or 31 1/9
Step-by-step explanation:
Jesse is going on 2 jumps, which is 14000*2=28000.
Each Skydive is $400, and two jumps would be $800. Plus a $100 training fee, it would cost $900 for 2 jumps.

ΔABC is similar to ΔMNO. The scale factor of ΔABC to ΔMNO is 3⁄2. What's the length of NO?
A. 4 units
B. 1 unit
C. 3⁄2 units
D. 6 units
Answer:
a
Step-by-step explanation:
When two triangles are similar, their corresponding sides are in proportion. The length of NO cannot be determined from the given information.
Explanation:When two triangles are similar, their corresponding sides are in proportion. In this case, the scale factor is 3/2, meaning that the corresponding sides of triangle ABC and triangle MNO are in the ratio of 3:2.
To find the length of side NO, we can set up the proportion:
AB/MN = BC/NO = AC/OO
Since we know that AB = 3 and MN = 2, we can solve for NO:
3/2 = BC/NO
3NO = 2BC
NO = (2/3)BC
Therefore, the length of NO is (2/3) times the length of BC.
Since we don't know the length of BC, we cannot determine the exact length of NO. The answer choices provided do not match the information given, so none of the given options can be correct.

A) 1600
B) 2467
C) 3370
D) 4502
First Place Vote: 4x867= 3468
Second Place Vote: 2x301= 602

Answer:
D) 4502
Step-by-step explanation:
It is given that,
Points for first place = 4 points
Second place = 2 points
Third place = 1 point
Thus, First Place Vote : 4 × 867 = 3468
Second Place Vote: 2 × 301= 602
Third Place Vote: 1 × 432= 432
Thus, Total Points = 3468 + 602 + 432 = 4502.

What are the domain and range of the piecewise function below? HELP ASAP
The domain is the set of all point where you can evaluate the function.
As you can see, the first piece is defined from -infinity to 2 (included).
The second piece is defined from 2 to 6 (excluded).
The third piece is defined from 6 (excluded) to +infinity.
So, the domain of the function is composed by all the real numbers which are not 6:
[tex](-\infty,6)\cup(6,\infty) = \mathbb{R}\setminus\{6\} = \{x \in \mathbb{R}\ :\ x\neq 6\}[/tex]
As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.
The second piece is constantly equal to 2, so it adds nothing.
The third piece spans the y axis from -2 to -infinity, so the range is
[tex](-\infty,-2)\cup[0,\infty) = \mathbb{R}\setminus [2,0) = \{x \in \mathbb{R}\ :\ x\geq 0\ \lor\ x<-2\}[/tex]

Harold moves no more than 43 of his sheep and goats into another field. Fewer than 22 of his animals are goats.
Let s represent the number of sheep and g represent the number of goats identify two inequalities that represent this situation.
A. g<22
B. s>22
C. s+<43 with the line under
D. s-g<45 with the line under
Answer:Options 'A' and 'C' are correct.
Step-by-step explanation:
Let the number of sheep be 's'.
Let the number of goats be 'g'.
According to question, we have given that
the number of sheep and goats are not more than 43.
The number of goats are fewer than 22.
So, the inequalities would be
[tex]g<22\\\\and\\\\s+g<43[/tex]
Hence, Options 'A' and 'C' are correct.
The two inequalities for Harold's sheep and goats situation are A. g < 22 and C. s + g ≤ 43.
To represent the situation described about Harold's sheep and goats, we need to set up two inequalities based on the given information:
A. g < 22: This inequality indicates that the number of goats (g) is fewer than 22.C. s + g ≤ 43: This inequality means that the total number of sheep and goats combined (s + g) is at most 43.Using these inequalities, we can help Harold determine how to distribute his sheep and goats in the new field.

Answer:
x^2 + y^2 + 6x - 8y + 21= 0.
Step-by-step explanation:
The center of this circle is (-3, 4) and the radius id 2.
So in Standard form, the equation is:
(x + 3)^2 + ( y - 4)^2 = 2^2
Converting to General form we have:
x^2 + 6x + 9 + y^2 - 8y + 16 = 4
x^2 + y^2 + 6x - 8y + 9 + 16 - 4 = 0
x^2 + y^2 + 6x - 8y + 21= 0.

Which of the following is equal to sqrt. (50(a^6) (b^7))
Answer:
5 · a³ · b³ · √5b
Step-by-step explanation:
Start with √(50a^6b^7). Rewrite 50 as the product of the largest possible perfect square and a multiplier: 50 = 25 · 2. Then √50 = 5√2.
a^6 is already a perfect square, so find its square root: √a^6 = a^3.
b^7 = b · b^6, so √b^7 = b^3√b
Now rewrite (50(a^6) (b^7)) as √(50a^6b^7).
Then rewrite √(50a^6b^7) as 5√2 · a³ · b³ · √b.
This latter result can be simplified to 5 · a³ · b³ · √5b
This matches possible answer #1.
The sum of two numbers is equal to 63 and their difference is equal to 12. Find the numbers.
Answer:
a + b = 63
a - b = 12
So, a - b = 12 which can also be written as a = b + 12
Then use substitution and plug in (b + 12) for a in the first equation
(b+12) + b =63
-12 -12
---------------------
2b = 51 so b=25.5
Now, you know b which can be used to find a
63- 25.5= 37.5
So, a = 37.5 and b = 25.5
Answer:
25.5 and 37.5
Step-by-step explanation:
37.5-12=25.5
25.5+37.5=63
