Answer:
0.2% of the people had mid allergic reaction.
Step-by-step explanation:
Given that:
Number of people tested for a new shampoo = 9000
Number of people who had allergic reaction = 18
Percent of people = [tex]\frac{People\ who\ have\ reaction}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{18}{9000}*100[/tex]
Percent of people = 0.002 * 100
Percent of people = 0.2%
Hence,
0.2% of the people had mid allergic reaction.
For lawn mowing, Jeremy charges a flat fee of $5 plus $10 per hour. Write an equation for cost and hours of lawn mowing. What is the slope?
Answer:
y = 10x+5
Slope is 10 dollars per hour
Step-by-step explanation:
y = mx+b where m is the slope and b is the y-intercept or flat fee, here.
b = 5
10 per hour means m = 10
What is the domain of the function shown on the graph?
Answer:
The domain of the graph is:
-∞ < x < ∞
Hence, option B is correct.
Step-by-step explanation:
We know that the domain of the function is the set of input or arguments for which the function is real and defined.
In other words,
Domain refers to all the possible sets of input values on the x-axis.From the given graph, we can easily observe that the graph extends horizontally to the left without bound, as well as to the right without bound.
Therefore, the domain of the graph is:
-∞ < x < ∞
Hence, option B is correct.

Answer:
4). [tex]-\frac{27}{28}[/tex]
5). Amount payable by the customer = 1416 Rs.
Step-by-step explanation:
4). [tex](\frac{3}{7})\times (-\frac{5}{8})\div (\frac{1}{3}\times \frac{5}{6})[/tex]
= [tex](-\frac{15}{56})\div (\frac{5}{18})[/tex]
= [tex](-\frac{15}{56})\times \frac{18}{5}[/tex]
= [tex]-\frac{54}{56}[/tex]
= [tex]-\frac{27}{28}[/tex]
5). Cost of the item = Rs 1200
G.S.T. applicable on this item = 18%
Amount to be paid for G.S.T.= 1200 × [tex]\frac{18}{100}[/tex]
= Rs 216
Total amount payable by the customer = Cost + G.S.T.
= 1200 + 216
= Rs 1416
Hardest hw question on the Homework can you solve it?
the ratio of the heights of two similar pyramids is 2:5 in the volume of the smaller pyramid is 100 cubic feet, find the volume of the large pyramid
Volume is a cubic measurement.
Set up a ratio of volume to the ratio of the height:
100/v2 = 2^3/5^3
V2 = 100 x 5^3/2^3 = 100 x 125/8 = 1,562.5 cubic feet
The volume of large pyramid is 1,562.5 cubic feet, by using ratio of heights.
Volume of pyramid based problem:What information do we have?
Ratio of heights of two similar pyramids = 2:5
Volume of smaller pyramid = 100 cubic feet
Volume of smaller pyramid / Volume of large pyramid = Height of smaller pyramid³ / Height of large pyramid³
100 / Volume of large pyramid = 2³ / 5³
Volume of large pyramid = 125(100) / 8
Volume of large pyramid = 1,562.5 cubic feet

Earning (y) : ____ 5 ____ 10 ____ 15 ____ 20
Boxes sold (x) :__ 2 ____ 4 _____ 6 ____ 8
Answer:
$2.5
Step-by-step explanation:
Given:
Earning varies directly as the number of boxes of cookies sold
y α x
y = kx - - - (1)
k = constant of proportionality (earning per box of cookies sold)
Taking any 2 points :
y = 10 ; x = 4
10 = k4
10 = 4k
Divide both sides by 4
10/4 = 4k/4
2.5 = k
Hence, the amount earned per box of cookies sold is $2.5

Answer:
x = 37
Step-by-step explanation: Every angle in a triangle adds up to 180, so we can set up an equation where (x + 48) + (x + 58) = 180. From here, we can combine like terms to get 2x + 106 = 180. 180-106 is 74. 74 divided by 2 is 37. So, x = 37.

C. square 2
D. square 2 / 2
Answer:
sin90° = 1.
Step-by-step explanation:
Using the diagram, we notice that the side opposite of the 90° angle is the hypotenuse itself.
Therefore sin90° = Hypotenuse/Hypotenuse = 1.
The force, F newtons, exerted by a magnet on a metal object is inversely
proportional to the square of the distance d cm.
When d = 2 cm, F= 50 N.
Express F in terms of d.
Answer:
F = 200/d^2
Step-by-step explanation:
F is inversely proportional to d^2
The equation is;
F = k/d^2
K = F•d^2
so to get k, we substitute the given values
K = 50 * 2^2
K = 50 * 4
K = 200
So we have that;
F * d^2 = 200
F = 200/d^2

Answer:
x = 2, y = 6
Step-by-step explanation:
I'm assuming you're finding the pattern and then finding x and y, in which case it would be:
In the first one (x, 3, 4, 5, 6) you can see it goes up by 1 each time so x is just 2.
In the second one (y, 9, 12, 15, 18) it goes up by 3 each time so y = 9-3 = 6.

what is the quotient (3x^2 + 8x -3) divided by (x + 3)
Answer:
Quotient = (3x-1)
Step-by-step explanation:
we need to find the quotient when (3x² + 8x -3) is divided by (x+3)
It means we need to divide (3x² + 8x -3) by (x+3).
We can write it as follows :
[tex]\dfrac{3x^2 + 8x -3}{(x+3)}[/tex]
Applying middle term splitting on the numerator.
[tex]\dfrac{3x^2 +9x-x-3}{(x+3)}\\\\=\dfrac{3x(x+3)-1(x+3)}{(x+3)}\\\\=\dfrac{(3x-1)(x+3)}{(x+3)}\\\\=(3x-1)[/tex]
So, the required quotient is (3x-1)

x problems 4 minutes
____________________
[tex] \frac{45.4}{30} = \frac{180}{30} = 6[/tex]
We learnt this way in Turkey.
Answer: 6 problems in 4 minutes
Step-by-step explanation: If there are 45 problem and she can do them in 30 minutes, then you divide 45 by 30 to see how many problems she can do in one minute. 45 problems/30 minutes = 1.5 problems per minute. Then, you multiply 1.5 by 4, because you need to see the 4 minute mark, and 1.5 x 4 = 6. So, your answer is 6 problems.
