Find m <ABC (7x-1) (3x-9
Answer:
Therefore, [tex] \angle ABC = 48\degree[/tex]
Step-by-step explanation:
We need to find the [tex] \angle ABC[/tex]
Since, [tex] \angle DBC = 180\degree[/tex] ( since DBC is straight line )
[tex](7x-1)+(3x-9)=180\degree[/tex]
[tex]10x-10=180 \degree[/tex]
Add both the sides by 10 in above expression
[tex]10x-10+10=180\degree+10[/tex]
[tex]10x=180 \degree+10[/tex]
[tex]10x=190 \degree[/tex]
divide both the sides by 10 in above expression
[tex]x=\frac{190}{10}[/tex]
[tex]x=19 [/tex]
Hence, the value of x is 19.
Now, we will calculate [tex] \angle ABC[/tex]
[tex] \angle ABC = 3x-9[/tex]
Put x = 19 in above
[tex] \angle ABC = 3(19)-9[/tex]
[tex] \angle ABC = 57-9[/tex]
[tex] \angle ABC = 48[/tex]
Therefore, [tex] \angle ABC = 48[/tex].
PL has endpoints P(4, −6) and L(−2, 1). The segment is translated using the mapping (x, y) → (x + 5, y). What are the coordinates of P’ and L’? P’(9, -6), L’(-2, 1) P’(4, -6), L’(3, 1) P’(9, -6), L’(3, 1) P’(9, -1), L’(3, 6)
Answer: C P’(9,-6), L’(3,1)
The coordinates of P' and L' after the translation are (9, -6) and (3, 1) respectively.
Explanation:A translation rule in mathematics describes the process of moving a geometric figure from one location to another without changing its shape or orientation. It involves shifting the figure horizontally or vertically by a certain distance. Translation rules are essential in geometry and are used to analyze and manipulate shapes on a coordinate plane.
The segment PL has endpoints P(4, -6) and L(-2, 1). To find the coordinates of P' and L' after being translated using the mapping (x, y) → (x + 5, y), we simply add 5 to the x-coordinates of P and L. Therefore, the coordinates of P' are (4 + 5, -6) which is equal to (9, -6), and the coordinates of L' are (-2 + 5, 1) which is equal to (3, 1).

Leon bought a dozen daisies for $3.75. What is the amount he paid per daisy (round to the nearest hundredth place)?
The amount he paid for per dairy is (rounded to the nearest hundredth would be) $0.31 (31 cents)
What is division?Division is the process of splitting a number or an amount into equal parts.
Here, given that,
Leon bought a dozen dairies for $3.75
i.e. cost of 12 dairies = $3.75
Then, cost of per dairy = $3.75÷12
=$0.3125
(The answer would be $3.75/12 which equals to $0.3125. )
Hence, The amount he paid for per dairy is $0.31.

Step-by-step explanation:
What scientific value for n will make this equation true?
(4.8 × 10–3)(n) = 9.6 × 109
To make the equation (4.8 × 10^–3)(n) = 9.6 × 10^9 true, the value of n is 2 × 10^12.
Explanation:To make the equation (4.8 × 10–3)(n) = 9.6 × 109 true, we need to find the value of n. Let's solve the equation:
First, divide both sides of the equation by (4.8 × 10–3). This simplifies the equation to n = (9.6 × 109) / (4.8 × 10–3).
Next, simplify the right side of the equation by dividing the numbers and subtracting the exponents: n = (9.6 / 4.8) × 109-(-3) = 2 × 1012.
Therefore, the scientific value for n that makes the equation true is 2 × 1012.
Final answer:
To solve for n in the equation (4.8 × 10–3)(n) = 9.6 × 10⁹, divide both sides by 4.8 × 10–3. After dividing the coefficients and subtracting the exponents, the scientific value for n is 2 × 10².
Explanation:
To find the scientific value for n that makes the equation (4.8 × 10–3)(n) = 9.6 × 10⁹ true, we need to isolate n by dividing both sides of the equation by 4.8 × 10–3.
Divide each side by 4.8 × 10–3 to get:
n = (9.6 × 10⁹) / (4.8 × 10–3)
Now, we divide the coefficients (9.6/4.8) and subtract the exponents of 10 (9 - (-3)) to find n:
n = 2 × 10²
So, the scientific value for n is 2 × 10².

you have 12 cups of granola and 8 1/2 cups of peanuts to make trail mix. what is the greatest number of full batches of trail mix can you make?
To determine the greatest number of full batches of trail mix that can be made, divide the total quantity of each ingredient by the required amount per batch.
Explanation:To determine the greatest number of full batches of trail mix that can be made, we need to compare the quantities of granola and peanuts. First, we calculate the number of full batches we can make using granola. Since each batch requires 12 cups of granola, we divide the total quantity of granola (12 cups) by the required amount per batch (12 cups). The result is 1 full batch.
Next, we determine how many batches we can make using the peanuts. Since each batch requires 8 1/2 cups of peanuts, we divide the total quantity of peanuts (8 1/2 cups) by the required amount per batch (8 1/2 cups). The result is 1 full batch.
Therefore, the greatest number of full batches of trail mix that can be made is 1 batch.

if it takes 3 hours for 8 workers to paint a fence, how long would it take for 6 workers.
SHOW WORKING
Final answer:
It would take 6 workers 4 hours to paint the fence, as the total amount of work, 24 worker-hours, divided by 6 workers, gives 4 hours.
Explanation:
Let's tackle the problem by first determining the total amount of work done when 8 workers paint a fence in 3 hours. This work can be considered as 24 worker-hours (since 8 workers * 3 hours = 24 worker-hours). This total amount of work would stay the same regardless of the number of workers. So if 6 workers are going to do the same job, we'd divide the total work by the number of workers to find out how many hours it would take for 6 workers to complete the task.
Dividing the 24 worker-hours by 6 workers, we get:
24 worker-hours / 6 workers = 4 hours
Therefore, it would take 6 workers 4 hours to paint the fence.
