Responder:
40 instalações
Explicação passo a passo:
Rolos totais de instalações adquiridas = 15
Rolos usados por instalação = 3/8 de um rolo
O número de instalações que os 15 rolos podem durar pode ser calculado assim:
1 instalação = 3/8 rolo
x instalações = 15 rolos
Multiplicação cruzada
3/8 x = 15
x = 15 ÷ 3/8
x = 15 * 8/3
x = 5 * 8
x = 40

Please answer asap with explanation
Answer:
x^2 = 44y
It's really hard to explain
but if the directrix is y then your problem will have X^2= if it was x then the problem would have y^2=
then you have to have the y on the other side of the equation
and you want to multiply the 11 by 4. always multiply by 4.

Can somebody help me with this pleaseee!!! Help will be very appreciated And may you explain why it’s a lie .
Answer:
my mother say it is B. she is good at math
Answer: A
Step-by-step explanation:
Answer A is a lie. The most obvious reason being the other two statements can be proven because the y intercept of the exponential IS (0, 1). Secondly, the point (-2, 4) CAN be found on the graph. Option A is the lie because if you look, for x = 10, y = 0. Therefore, the statement that for very large values of x the exponential has very large values of y, is a lie.

The librarian continues to record the type of item that the next 20 patrons check out from the library. patron item type 11 fiction book 12 non-fiction book 13 fiction book 14 fiction book 15 fiction book 16 non-fiction book 17 fiction book 18 non-fiction book 19 fiction book 20 DVD 21 fiction book 22 non-fiction book 23 fiction book 24 fiction book 25 audiobook 26 fiction book 27 DVD 28 non-fiction book 29 fiction book 30 DVD Based on the information from these patrons, estimate the probability that the next patron will check out a fiction book.
Answer:
[tex]Pr = 0.55[/tex]
Step-by-step explanation:
Given
Represent the dataset with the following frequency table
[tex]\begin{array}{cc}{Item} & {Frequency} & {Fiction\ Book} &{11} & {Non\ Fiction\ Book} & {5} & {DVD} & {3} & {Audiobook} & {1} \ \end{array}[/tex]
Required
Probability that the next checkout will be fiction
From the above frequency table, we have:
[tex]Fiction\ Book = 11[/tex]
[tex]n =20[/tex] --- total
So, the probability that the next checkout item is a fiction book is:
[tex]Pr = \frac{Fiction\ Book}{n}[/tex]
[tex]Pr = \frac{11}{20}[/tex]
[tex]Pr = 0.55[/tex]

find the value of x. 49° x°
Answer:
x = 41
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 90 + 49 = 180
x + 139 = 180
x = 180 - 139
x = 41

Find the radius r of the circle. Round your answer to the nearest tenth.
Answer:
1.1 yd
Step-by-step explanation:
120 × π/180 = 2π/3
2.3 = r × 2π/3
=> r = 2.3 ÷ 2π/3
=> r ≈ 1.1
The required measure of the radius is given as 1.1 yd.
What is a circle?The circle is the locus of a point whose distance from a fixed point is constant i.e center (h, k). The equation of the circle is given by
(x - h)² + (y - k)² = r²
Where h, k is the coordinate of the center of the circle on the coordinate plane and r is the radius of the circle.
Here,
Angle = arc/radius,
Substitute the value in the above equation,
120 = 2.3 / radius,
radius = 2.3 / 120 × 180 / π
radius = 2.3 / 12 × 18 / 3.14
radius = 1.1 yd
Thus, the required measure of the radius is given as 1.1 yd.

What is the surface area of the cylinder shown below? Use 3.14 for π. A. 660 cm2 B. 863 cm2 C. 353.25 cm2 D. 785 cm2
Answer:
602.88cm²
Step-by-step explanation:
Find the image of the cylinder attached
Surface area of a cylinder = A=2πrh+2πr²
r is the radius = 4cm
Height h = 20cm
Substitute
A = 2πr(r+h)
A = 2π(4)(4+20)
A = 8π(24)
A = 192π
A = 192(3.14)
A = 602.88cm²
Hence the surface area of the cylinder is 602.88cm²

Suppose that the probability that your
mail is delivered before 2 pm is .90.
What is the probability that your
mail
will be delivered before 2 pm for two
consecutive days? Give your answer as
a decimal.
Answer:
The probability is 0.81
Step-by-step explanation:
The probability we want to find here is that;
the mail was delivered before 2 pm the first day and also delivered before 2 pm the next day
what we have to do here is to
multiply together, the probability in the two cases (for both days)
So we have this as:
0.9 * 0.9 = 0.81
Answer:
.81

There is a triangle with sides measuring 301, 30in and 25. Is this a nighttrange? Why or why not?
Answer:
No
Step-by-step explanation:
Assume you are asking if 30 in, 30 in, 25 in triangle if right.
Since two longer sides are equal this can't be a right triangle. Remember the hypotenuse is the longest side and the right triangle can be isosceles if shorter sides are of same size.

A coin is flipped 10 times. Based on theoretical probability, how many times will it likely result in heads?
3 out of 10 B. 4 out of 10 C. 5 out of 10 D. 6 out of 10
Answer:
answer: C. 5 out of 10
Step-by-step explanation:
Theoretical probability is what is expected to happen sense a coin has 2 sides theres a 1/2 chance at getting heads so 5 out of 10 is the theoretical probability because 5 is half of 10 hope this helps!

what does 45=-3x tell me
Answer: x = -15
Hope this helps :)
Answer:
x = -15
Step-by-step explanation:
[One step multiplication problem]
When solving a one-step multiplication problem the easiest thing to do would be to divide the 'answer' (in this case, 45) by the coefficient (in this case, -3). A negative number times a negative number is a positive number, so x would be a negative number. 45 divided by -3 is -15.
So, x = 15.

What percent is 25/75?
Answer:
33.33%
Step-by-step explanation:
Answer:
33.3333%
explaination
When we are using percentages, what we are really saying is that the percentage is a fraction of 100. "Percent" means per hundred, and so 50% is the same as saying 50/100 or 5/10 in fraction form. Now we can see that our fraction is 33.333333333333/100, which means that 25/75 as a percentage is 33.3333%
