The points (10, 6) and (7, u) fall on a line with a slope of -4/3. what is the value of u?
Aleks [24]
Answer:
u = 10

Explanation:
The slope of the lone can be calculated as follows:
slope = (y2-y1) / (x2-x1)

We are given:
slope = -4/3
point (10,6) representing (x1,y1)
point (7,u) representing (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
-4/3 = (u-6) / (7-10)
-4/3 = (u-6) / -3
4/3 = (u-6) / 3
3*4 = 3*(u-6)
4 = u-6
u = 4+6
u = 10

Hope this helps :)

mr. cook earns a salary of $150 a week plus an 8% commission on all sales. how much will he earn if his sales this week are $2,9
Maksim231197 [3]

1. Turn 8% into a decimal. Multiply the product by 2,990.

8%=0.08 0.08×2,990=293.2

$293.20 is the amount of commission Mr.Cook will earn this week.

2. To find the total, add $293.20 to $150.

$293.20+$150= $389.20

Mr.Cook will earn a total of $389.20 this week.

ANSWER ASAP The questions on a multiple-choice test each have 5 answer choices.
Len [333]

Answer:

F, spinning a spinner with five equal sections

Step-by-step explanation:

The probability of something is (the ways to acheive the wanted outcome / all possible situations)

For example, the probability of getting heads on a coin flip is (1 possible way to get heads / 2 possible outcomes) = 1/2, or 50/50

Now, onto the problem.

There is only one way to get the answer right, and 5 possible situations. So, the probability of getting the question right would be 1/5.

F) Spinning a spinner with five parts means that you have: 1 way to get the right section, and 5 possible outcomes. So, the probability of getting the right section would be 1/5. So, this answer is correct.

G) Flipping a coin five times: Each time, you have a 1/2 chance of the coin landing on the desired side. So, this would not be an accurate comparison.

H) Spinning a spinner with four equal sections: There is one way to land on the desired section, and 4 possible outcomes. So, the probability of this simulation is 1/4, so this answer is incorrect.

I) Rolling a number cube labeled one through six times: Each time, there is one way to land on the number you want, while there are six possible outcomes. So, the probability of getting your desired number is 1/6, which is incorrect.

I hope this helps! Feel free to ask any questions!

The ratio of the loudness of lala's earphones to the loudness of polina's earphones to the loudness of goffy's earphones is 6:5:
tresset_1 [31]
Let:
Lala be l
Polina be P
Goffy be G
the respective ratio is 6:5:3
Given that Polina's loudness is 420 decibels then the total loudness will be calculated as follows:
Total ratio=6+5+3=14
hence total loudness will be:
14/5×420
=1,176 decibels
