The number of days, d, that it will take to build a house is given by
d= 720 divided by n
where n is the number of workers used each day.
Ali's company will take 40 days to build the house.
Hayley's company will take 30 days to build the house.
Hayley's company will have to use more workers each day than Ali's company.
How many more?
Answer:
6 more workers
Step-by-step explanation:
The relationship between days (d) and number of workers (n) is given by the equation;
d = 720 / n
Ali's company will take 40 days to build the house.
n = 720 / d
n = 720 / 40 = 18 workers
Hayley's company will take 30 days to build the house.
n = 720 / d
n = 720 / 30 = 24 workers
Hayley's company will have to use more workers each day than Ali's company.
How many more?
24 - 18 = 6 more workers
a baby goraffe is about 6 1/2 feet tall at birth and grows about 1/2 foot per month for its first year. The function h=1/2m+61/2 represents the total height h of a baby giraffe for any number of months m within ita firat year. How much taller is the giraffe at the end of the month 11 than at the end of month 2
Answer: 4 and 1/2 ft (or 4.5 ft) taller.
Step-by-step explanation:
The function h(m) = (1/2)*m + (6 + 1/2) represents the height (on feet) of the giraffe as a function of the number of months, m.
We want to find the difference in the height between month 11 and month 2, then we need to find:
difference = h(11) - h(2)
We can directly calculate this:
difference = [ (1/2)*11 + (6 + 1/2)] - [(1/2)*2 + (6 + 1/2)]
difference = (1/2)*11 - (1/2)*2 = (1/2)*(11 - 2) = (1/2)*(9) = 9/2
And we can write 9 = 9 + 1, then:
difference = 9/2 = (8 + 1)/2 = 8/2 + 1/2 = 4 + 1/2
And this is in feet, then the girrafe is (4 and 1/2) ft taller on month 11 than on month 2.

A graph shows Hours Spent Studying on x axis and Test Score on y axis .The graph is shown with scale along x axis from 0 to 10 at increments of 1 and scale along y axis from 0 to 100 at increments of 10. The ordered pairs 0, 21 and 0.8, 32 and 1.2,35 and 1.5,39 and 2.1, 42 and 2.3,45 and 2.5,49 and 2.7, 50 and 3, 67 and 4.6, 56 and 5, 69 and 5.3,70 and 5.7,74 and 6.4,78 and 7.2,80 and 7.5,84 and 8.5,88 and 8.7,92 and 9.5,96 are shown on the graph. What will most likely happen to the test scores of students if the number of hours they study increases? Test scores will increase because the graph shows a negative association. Test scores will increase because the graph shows a positive association. Test scores will decrease because the graph shows a positive association. Test scores will decrease because the graph shows a negative association.
Answer:
Test scores will increase because the graph shows a positive association.
Step-by-step explanation:
Since it is going upwards to the right instead of going downwards and for the people who steady more hours they get better scores on there test.
btw i just took it and got it right
From given scatter plot, if the number of hours they study increases then the test scores will increase because the graph shows a positive association.
What is scatter plot?"A type of data representation that shows the relationship between two numerical variables. "
What is positive association?"When the values of one variable tend to increase as the values of the other variable increase, then two variable have positive association."
What is negative association?"When the values of one variable tend to decrease as the values of the other variable increase, then two variable have negative association."
For given question,
The scatter plot shows the test scores of a group of students who studied for different amounts of time in a week.
A scatter plot shows Hours Spent Studying on x axis and Test Score on y axis .

From the given data points of scatter plot,
as x - value increases, y - value also increases.
This means, if the number of hours they study increases, the test scores will increase.
Here, the values of one variable tend to increase as the values of the other variable increase.
This means, there is positive association in variables Hours Spent Studying and Test Scores.
Therefore, from given scatter plot, if the number of hours they study increases then the test scores will increase because the graph shows a positive association.

This question is worth 2 points! Allison makes and sells beaded necklaces. She charges a flat fee of $5 per necklace, and $1.50 per bead that she adds. If Jennifer, who wants to purchase a necklace, has $34 to spend, how many beads can she add to her necklace? Explain the process you used to solve, and tell what your answer is.
Answer:
19 beads
Step-by-step explanation:
If Jennifer has 34$ she automatically loses 5$ because that's the fee for the necklace. So, you subtract 34 from 5 and you get 29. After that you divide 29 by 1.50 and you get 19.333333. But, since you can't get 1/3 of a bead Jennifer can only buy 19 beads.
In 2071 the monthly salary of the Chief justice of
Nepal was Rs. 53580. If 1 % tax was levied on firs
Rs. 300000 and certain rate on remaining so that the
chief justice paid Rs. 4537 monthly tax. How much
was the tax percentage on remaining? (Ans: 15%)
Answer:
Step-by-step explanation:
There must be an error—or multiple errors—in the question. Rs 300,000 doesn't make sense, because that would mean he was due a tax refund.
Rs 30,000 doesn't work, either, because that would mean he was paying 18% tax, not 15%.
If a 1% tax was levied on the first Rs 25,000, then he would pay Rs 4,287 on on the remaining Rs 28,580, which would work out to 15%.

What is linear expression?A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
The results of a linear regression are shown below,
⇒ y = ax + b
⇒ a = -1.15785
⇒ b = 139.3171772
⇒ r = -0.896557832
⇒ r₂ = 0.8038159461
Now,
With the value of r we have both the information about the sign of the relationship and the strength of this relationship.
⇒ As the value of r is negative, we can conclude that the correlation between x and y is negative.
Also, as the absolute value of r is close to 1, we can conclude that this relationship is strong.
And, The strength can also be seen in the value of r2, which is also close to 1, but this value does not give information about the sign.
Thus, The value of the slope a, being negative, can also tell us that the relation between x and y is a negative correlation.

Answer:
Step-by-step explanation: add 15, 25 and 39
then subtract by 180
Answer:
101
Step-by-step explanation:
(There is a shorter way to solve this, is in the other answer omg sorry)
First we have to find the last angle of the smallest triangle.
The addition of all angles in a triangle is always 180º so that means:
39 + 25 + y = 180
y = 180 - 64
y = 116
Now that we know the value of that angle we can find the other angle (not x) and with it we can get the answer.
Because flat angles are 180º too
Then:
116 + z = 180
z = 180 - 116 = 64
Finally now we calculate the addition of all angles again to find x:
x + 15 + 64 = 180
x = 180 - 79
x = 101

Mai, Clare, and Tyler are hiking from a parking lot to the summit of a mountain. They pass a sign that gives distances. 3 • Parking lot: 3/4 mile • Summit: 1 1/2 miles Mai says: "We are one third of the way there." Clare says: "We have to go twice as far as we have already gone." Tyler says: “The total hike is three times as long as what we have already gone." a) Can they all be correct?
Answer:
Yes they can
Step-by-step explanation:
.
Tyler's statements are consistent with the given distances.
To determine if Mai, Clare, and Tyler can all be correct, we need to evaluate the statements they made in relation to the given distances.
Statement 1: Mai says, "We are one third of the way there."
The distance from the parking lot to the summit is 1 1/2 miles. If they are one third of the way there, the distance they have already traveled would be 1/3 * 1 1/2 miles = 1/3 * 3/2 miles = 1/2 mile. However, the given distance from the parking lot is 3/4 mile, which is greater than 1/2 mile. Therefore, Mai's statement cannot be correct.
Statement 2: Clare says, "We have to go twice as far as we have already gone."
If they have already gone a distance of x, then according to Clare's statement, they have to go a distance of 2x. This statement does not contradict the given distances, so it could be true.
Statement 3: Tyler says, "The total hike is three times as long as what we have already gone."
If they have already gone a distance of x, then according to Tyler's statement, the total hike would be 3x. This statement also does not contradict the given distances, so it could be true.
Based on the analysis, only Mai's statement cannot be correct. Clare and Tyler's statements are consistent with the given distances.
