Final answer:
The unit rate of 2134 meters in 212 hours is approximately 10.063 meters per hour. This calculation involves dividing the total distance by the total amount of time.
Explanation:
To find the unit rate of 2134 meters in 212 hours, we need to calculate how many meters are covered in one hour. The unit rate is computed by dividing the total distance by the total time.
The calculation is as follows:
Unit rate = Total distance / Total time
Unit rate = 2134 meters / 212 hours
Calculating this gives us a unit rate of approximately 10.063 meters per hour. It's important to make sure that the result is reasonable. If you travel a certain distance in a given number of hours, dividing the distance by the time should give you how many meters you travel in one hour, which in this case, it does.

A pair of parallel lines is cut by a transversal. One of the angles formed measures 58°. Which statements about the other seven angles formed are true? (multiple answers)
There are three more angles with the same measure.
All the other angles have the same measure.
The rest of the angles measure 122°.
Only three of the angles measure 122°.
Four of the angles measure 122°.
Answer:
Correct options are 1 and 5.
Step-by-step explanation:
If parallel lines m and n are cut by a transeversal t, then corresponding angles are equal in measure. Therefore,
∠2≅∠6;
∠1≅∠5;
∠3≅∠7;
∠4≅∠8.
If parallel lines m and n are cut by a transeversal t, then interior angles on the same side are supplementary. Thus,
∠3+∠5=180°;
∠4+∠6=180°.
If one of the angles ( let it be angle 3) formed measures 58°, then m∠5=180°-58°=122°. Then
m∠2=m∠3=m∠6=m∠7=58°;
m∠1=m∠4=m∠5=m∠8=122°.
You can conclude that there are three more angles with the same measure of 58° and four of the angles measure 122°.

d-2,-7,-12,-17,-22....
Answer:
Option c is correct.
The sequence is, 2, -3 , -8 , -13, -18, .....
Step-by-step explanation:
Given the following as;
f(1) = 2
The recursive function is;[tex]f(n) = f(n-1) -5[/tex] ......[1]
to find the sequence defined by the recursive function;
Put n=2 in [1];

find the measure of angle B, note that angle B is acute
Answer:
B= 44.9506°
Step-by-step explanation:
WE apply sine angle formula
[tex]\frac{a}{sin(A)} =\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
Given angle C = 51, c= 11 and b = 10
[tex]\frac{b}{sin(B)}=\frac{c}{sin(C)}[/tex]
Plug in the values
[tex]\frac{10}{sin(B)}=\frac{11}{sin(51)}[/tex]
Cross multiply it
10 * sin(51) = 11* sin(B)
7.771459615 = 11 sin(B)
Now divide by 11 on both sides
0.706496328 = sin(B)
Now [tex]B = sin^{-1} (0.706496328)[/tex]
B= 44.9506°
Answer each question. What is 35% of 90x? What percent of 16x is 9x?
Answer:
35% of 90x = 31.5
16x is 9x =
Step-by-step explanation:
35 /100 x 90 = 31.5
Answer:
31.5x; 56.25%
Step-by-step explanation:
For the first question:
We can write 35% as 0.35; this is because 35% = 35/100 = 0.35. Taking a percentage of a quantity means we multiply; this gives us
0.35(90x) = 31.5x
For the second question:
To find the percentage the second quantity is of the first one, we divide:
9x/16x = 0.5625
This is the same as 56.25%.
Maria and Andrew sold drinks from a lemonade stand in the summer. Because Maria built the stand they agreed that she should get twice as much of the profit as Andrew. If they made $187.41 profit how much money did Maria make?
Answer:
Maria made = $124.94
hope it helps
Step-by-step explanation:
if they made $187.41 and maria is getting twice a much as Andrew you'll divide 187.41 by 3 because maria is getting twice as more
187.41 ÷ 3 = 62.47
Andrew = 62.47
Maria = 62.47 x 2 = 124.94
to check your answer by adding 124.94 and 62.47 and should equal to the money made in total
124.94 + 62.47 = 187.41
Maria's profit from the lemonade stand business is calculated by dividing the total profit by 3 and then multiplying that amount by 2, as she is to receive twice as much as Andrew.
The question involves calculating Maria's share of the profit from their lemonade stand business. With a total profit of $187.41, and the agreement that Maria should receive twice as much as Andrew, we can set up an equation to solve the problem. Let's denote Maria's profit as M and Andrew's profit as A. The equation based on their agreement is M = 2A. Since the total profit is their profits added together, we have another equation: M + A = $187.41. Substituting the first equation into the second, we get: 2A + A = $187.41, which simplifies to 3A = $187.41. Dividing both sides by 3 to isolate A, A = $187.41 / 3. Calculating this gives us Andrew's profit, and multiplying A by 2 gives us Maria's profit.
9 out of 25 students are home sick with the flu. What percentage of the students are home sick?
Answer:
36%

9/25
multiply each by 4 to get 36/100
as a percent it would be 36%
The percentage of students who are homesick would be 36% which is 9 out of 25 students are home sick with the flu.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 12×2 = 24
We have been given that 9 out of 25 students are home sick with the flu.
We have to determine the percentage of students who are homesick
⇒ (9/25) × 100
Apply the division operation, and we get
⇒ 0.36 × 100
Apply the multiplication operation, and we get
⇒ 36%
Therefore, the percentage of students who are homesick would be 36%.

for a school fundraiser troy sold 28 bags of popcorn and 40 candy bars and made $282. Jake sold 17 bags of popcorn and 20 candy bars and made $160.50. What was the cost of the popcorn
To find the cost of the popcorn, set up a system of equations and solve them to find the value of x, which represents the cost of a bag of popcorn.
Explanation:To find the cost of the popcorn, we need to set up a system of equations. Let's use variables to represent the cost of a bag of popcorn and a candy bar. Let x be the cost of a bag of popcorn and y be the cost of a candy bar. We can set up two equations using the given information:
28x + 40y = 282
17x + 20y = 160.50
Now, we can solve this system of equations. Multiply the second equation by 2 to make the coefficients of x in both equations equal:
34x + 40y = 321
28x + 40y = 282
Subtract the second equation from the first equation:
34x - 28x + 40y - 40y = 321 - 282
6x = 39
Divide both sides of the equation by 6:
x = 6.50
Therefore, the cost of a bag of popcorn is $6.50.

Hope this help!!!!!!!!
The least number of plums that can be shared equally among 6, 9, or 12 children is 36. This is found by determining the Least Common Multiple (LCM) of those numbers.
Explanation:The subject of this question is math, specifically, it is about the concept of Least Common Multiple (LCM). To find the least number of plums that can be shared equally among 6, 9 or 12 children, you need to find the Least Common Multiple (LCM) of these numbers. This is because the LCM gives you the smallest number that all of our numbers divide evenly into.
Here's how you find the LCM of 6, 9, and 12:
Start by listing the prime factors of each number: 6 = 2 * 3, 9 = 3 * 3, and 12 = 2 * 2 * 3.Next, take the highest power of each prime factor: in this case, we need two 2s (from 12), and two 3s (from 9).Multiply these together to get the Least Common Multiple: 2 * 2 * 3 * 3 = 36.Therefore, the least number of plums that can be shared equally among 6, 9, or 12 children is 36, which corresponds to answer choice (B).

Step-by-step explanation:
Round 19.9 and 199 to 20 and 200
20*200 = 4000
Now subtract 20
20 * (200-1) = 4000-20
20 * 199 = 4000-20
20*199 = 3980
.1 of 200 is 20
so subtract 20
(20-.1) *200=3980-20
19.9 *200 =3960
(20-.1) *(200-1) = 3960
