Mr. Fry is building a fence around his pool.
•Length of the fence is 60 feet.
•Width of the fence is 30 feet.
How many yards of fence will Mr. Fry build?
Answer:
30 yards of fence
Step-by-step explanation:
First, convert 60 feet to yards and 30 feet to yards. Remember, 1 foot= 3 yards.
60/3= 20 yards
30/3= 10 yards
Then you add the length and the width of the fence (in yards) to find the total yards of fence.
20+ 10= 30 yards of fence

Which expression Is equivalent to x2-17x-60
Need work attached.
Answer:
Step-by-step explanation:
Find the roots of x² - 17x - 60
Quadratic formula
x = [17 ± √(17² – 4·1(-60))] / [2·1]
= [17 ± √529] / 2
= [17 ± 23] /2
= -3, 20
x² - 17x - 60 = (x+3)(x-20)
Answer:
(x+3)(x-20)
Step-by-step explanation:
x^2+3x-20x-60
x(x+3)-20(x+3)
= (x+3)(x-20)

Answer:
A: a = 100
B: b = 2
Step-by-step explanation:
The problem statement tells you that the population of bacteria is 100 at the start of our observation.
t = 0, f(t) = f(0) = 100
If you remember that a 0 exponent means the value is 1, then you know ...
f(0) = a·b^0 = a·1 = a
Since f(0) = 100, we know a = 100.
__
An exponent signifies repeated multiplication.
We know the population at t=0 is 100. At t = 1, we are told the population doubles. That means it is multiplied by 2.
f(1) = 100·b^1 = 100·2
b^1 = 2 . . . . . . . . . . . . . . . matching parts of these expressions
b = 2 . . . . . . . . . . . . . because b^1 = b

What is an equation of the line that passes through the points (-5, 6) and
(7, 6)?
Answer:
y = 6
Step-by-step explanation:
line of an equation: y = mx +c
where c is y-intercept, m is gradient and y and x are the y and x coordinates.
For finding the line of an equation we first find a gradient
gradient = (y2 -y1) / (x2 - x1)
so; (6-6) / (7-(-5)) = 0/12 = 0
next using any pair of coordinates we will find the c (y-intercept)
6= 0 (-5) + c
c = 6
so the equation will be
y = mx + c
(add the values you just found)
y = (0)x + 6 (since anything multiplied by 0 is 0 so we can write its like;)
y = 6

Find x.
I need the answer asap, please.
Answer:
x=28
Step-by-step explanation:
x+24+100+x=180

2x=180-124
2x=56
divide both side by number attached to the x

When you multiply a mixed number by ___________ ,the product is equal to the mixed number. What do you put in the blank?
Answer:
1
Step-by-step explanation:
because 1/2 time 1 = 1/2
Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. When you multiply a mixed number by another mixed number the product is equal to the another mixed number. For exact same mixed number, when you multiply a mixed number by one number the product is equal to the mixed number.
What is mixed number?Mixed number is the combination of the whole number and the proper fraction. One is integer and other is fraction in a mixed number. As it is the combination of two types of number thus it is known as mixed number.
Mixed number are used to count the whole and part of a thing together.
For example five and a half of a thing can be written as,
[tex]5+\dfrac{1}{2} =5\dfrac{1}{2}[/tex]
Now when a mixed number is multiplied by the another mixed number the product of both is a another mixed number.
For example let multiply 2 and a half with 3 and a half. The result is,
[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{7}{2} \times \dfrac{9}{2}[/tex]
[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =\dfrac{63}{4}[/tex]
[tex]2\dfrac{3}{2} \times3\dfrac{3}{2} =15\dfrac{3}{4}[/tex]
Thus when you multiply a mixed number by another mixed number the product is equal to the another mixed number.
If the product should be equal to the given mixed number thus it need to be multiplied by the one. Thus when you multiply a mixed number by one number the product is equal to the mixed number.

Market researchers were interested in the relationship between the price of bobbleheads and the demand of bobbleheads. Information was collected from a survey and used to obtain the regression equation ŷ = –0.227x + 50.455, where x represents the price of bobbleheads (measured in dollars) and ŷ is the predicted demand of bobbleheads (in units). What is the predicted demand of a bobblehead that has price of $6.00?
–1.362 units
49.093 units
51.817 units
195.837 units
Answer:
49.093
Step-by-step explanation:
Given the regression equation :
ŷ = –0.227x + 50.455
x represents the price of bobbleheads (measured in dollars)
ŷ is the predicted demand of bobbleheads (in units).
Preductwd demand ; when x = 6
ŷ = –0.227(6)+ 50.455
= 49.093

Answer:
x = 5
Step-by-step explanation:
the supplementary angle of (19x-18) = 180 - (19x-18) = 198-19x
all interior angles of a triangle = 180 degrees
180 = (7x+1) + (10x-9) + (198-19x)
180 = 7x+10X-19x+1-9+198
180 = -2x+190
-2x = -10
x = 5

Answer:
[tex]\boxed {\boxed {\sf b=60 \ meters}}[/tex]
Step-by-step explanation:
This is a right triangle because of the small square in the corner representing a 90 degree angle.
Therefore, we can use the Pythagorean Theorem.
[tex]a^2+b^2=c^2[/tex]
Where a and b are the legs and c is the hypotenuse.
80 and b are the legs, because they form the right angle. 100 is the hypotenuse because it is opposite the right angle.
[tex]a=80 \\b=b \\c=100[/tex]
[tex](80)^2+b^2=(100)^2[/tex]
Solve the exponents.
(80)²=80*80= 6400 (100)²= 100*100= 10000[tex]6400+b^2=10000[/tex]
Solve for the unknown by isolating the variable. First, subtract 6400 from both sides.
[tex]6400-6400+b^2=10000-6400\\b^2=3600[/tex]
Take the square root of both sides.
[tex]\sqrt {b^2}= \sqrt {3600}\\b=60 \\b= 60 \ m[/tex]
The missing leg is 60 meters.

A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies. You pick one candy at random. Find the
probability that it is purple or not red.
Answer:
97/139
Step-by-step explanation:
You add every thing but red so 45+20+32 which equals 97, so 97 is your numerator and to get the denominator you add all the numbers together so 42+45+20+32 which equals 139.
Probability that candy picked is purple or not red is [tex]\frac{32}{151}[/tex].
What is probability?The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes. The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes. Also, the favorable number of outcomes cannot be negative.
According to the question
A bag contains 42 red, 45 green, 20 yellow, and 32 purple candies.
You pick one candy at random.
We have to find probability that it is purple or not red.
Formula for probability:
[tex]P(E) = \frac{Number \ of \ favorable \ outcomes}{Total \ number \ of \ favorable \ outcomes}[/tex]
Total number of favorable outcomes = [tex]42+45+20+32 =151[/tex]
Number of favorable outcomes = 32
Probability that it is purple or not red.
[tex]P(E)=\frac{32}{151}[/tex]
Hence, Probability that candy it is purple or not red is [tex]\frac{32}{151}[/tex].

PLEASE HELP MEE EVERYONE IS WASTING MY POINTs PLEASE
==========================================================
Explanation:
For each row, divide the earnings over the sales.
In row 1, we have 22/673 = 0.0327 approximately In row 2, we have 37/1298 = 0.0285 approximately In row 3, we have 101/3277 = 0.0308 approximately In row 4, we have 150/5180 = 0.0290 approximatelyAll of these decimal values have the following conversions to percentages
0.0327 = 3.27% 0.0285 = 2.85% 0.0308 = 3.08% 0.0290 = 2.90%If we add up those percentages and divide by 4, we get the average percentage
(3.27+2.85+3.08+2.90)/4 = 3.025
So the average percentage of these four is 3.025%
So for instance, if you made $1000 in sales, then 0.0325*1000 = 32.50 would be the estimated earnings.
A good estimate in my opinion is the equation c = 0.0325d since 3.025% converts to the decimal form 0.0325
Another method you could use is linear regression to help estimate. Though this method is a lot more complicated involving many more steps. It's better to use technology (eg: graphing calculator) if you go this route. The linear regression line is approximately y = 0.02896x + 2.00732; we can see the slope 0.02896 isn't too far off from 0.0325. Other forms of regression are possible as well.
