Answer:

bro that is easy its 15*1/2

Step-by-step explanation:

Answer:

Volume=[tex]4x^3-44x^2+112x[/tex]

Step-by-step explanation:

Let x denotes the length of the side of each cut

After Cutting square length will be=8-2x (where 2x for 2 squares as on each side two corners are there thus 2 squares will be cut down)

After cutting square width will be=14-2x (where 2x for 2 squares as on each side two corners are there thus 2 squares will be cut down)

Height = x

Volume=Length*width*Height

Volume=(8-2x)*(14-2x)*x

On solving we will get:

Volume=[tex]4x^3-44x^2+112x[/tex]

Answer:

12 minutes

Step-by-step explanation:

The Hot tap fills 1/30th of the bath in 1 minute. The cold tap fills 1/20th of the bath in one minute. In one minute both taps together will fill (1/30 + 1/20) of the bath, which is 5/60ths or 1/12th of the bath. Since it takes one minute to fill 1/12th of the bath, it’ll take 12 minutes to fill the bath

Answer:

  1. attendance (y), time (x)

  2. 1,2: increasing; 3: constant; 4: decreasing

  3. attendance increases, remains constant, then decreases

  4. increasing; pre-heating the oven

Step-by-step explanation:

It is always difficult to read the mind of the author of questions like these. Usually, specific wording is expected. If your curriculum material has examples you can copy from, you should do that.

__

1. The variables and what they stand for are listed on the axes of the graph. The y-variable stands for attendance. The x-variable stands for time. It isn't clear whether the desired answer is "y and x" or "attendance and time".

__

2. The graph slopes upward in intervals 1 and 2. It can be described as "increasing."

The graph remains level in interval 3. It can be described as "constant."

The graph slopes downward in interval 4. It can be described as "decreasing."

__

3. The attendance is adequately described in question 2. Attendance increases, remains constant, then decreases. It isn't clear how general or specific the answer is supposed to be.

__

4. The graph of the function is "increasing." We don't know if the indicated temperature is the temperature of the bread, the oven, or the room containing the oven. If we assume the indicated temperature is that of the oven, we expect an increase during the oven pre-heat interval.

If the indicated temperature is that of the bread, then the increase would be following insertion of the bread into the oven.

Answer:

Answer:

40

Step-by-step explanation:

This is asking you to plug in the value of h(5) into g(x). First solve for h(5)

x^2-3 = h(x)

5^2-3= 22

h(5) = 22

h(5) is 22. So now, plug that into g(x).

g(h(5)) = 2(22)-4

44-4=40

(g.h)(5) is 40.

Answer:

117.8097 [tex]in^{2}[/tex]

Step-by-step explanation:

Depending on how you're math is going there are two ways to solve this,  find the are by the arc or just figure out the whole cookie and divide by 6.   Let's try the latter is seems easier to say.    I mean easier for me to say.  

area of a circle is pi * r^2

the diameter is 30 inches so the radius is half of that or 15 inches

then the whole cookie is

pi*15^2 = 706.858 [tex]in^{2}[/tex]

now divide by 6 or each piece

706.858 [tex]in^{2}[/tex] / 6 = 117.8097 [tex]in^{2}[/tex]

now eat your cookie  :p

[tex]\\ \sf\longmapsto x+43+143=180[/tex]

[tex]\\ \sf\longmapsto x+186=180[/tex]

[tex]\\ \sf\longmapsto x=180-186[/tex]

Answer:

  x = 4

Step-by-step explanation:

The inverse variation means that when y goes up by a factor of 20/5 = 4, the value of x goes down by the same factor.

  x = 16/4

  x = 4

-1.833 ; we do not reject the Null.

Pvalue = 0.0409 ; We do not reject the Null

There is no significant evidence to conclude that the number of ounces contained in the cereal boxes is less than 13

Step-by-step explanation:

H0 : μ = 13

HA : μ < 13

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(12.8 - 13) ÷ 0.5/sqrt(21)

-0.2 / 0.1091089

= - 1.833

The critical value at α = 0.01 ; df = 21 - 1 = 20 = 2.528

-1.833 > - 2. 528 (left tailed test) ; Hence we do not reject the Null.

Test statistic :

Pvalue from Test statistic at DF = 20 ; α = 0.01

Pvalue = 0.0409

Pvalue > α

0.0409 > 0.01 ; Hence, we do not reject H0.

Answer:

If you share 7 apples equally with 3 people, then there are 2 1/3 apples per person.

The number 2 represents the number of whole apples each individual gets.

The denominatior, 3, represents how many times an apple will have to be split to divide equally

The numerator, 1, represents how many 3rds each person gets.

Given:

[tex]f(x)[/tex] is continuous, [tex]f(3)=1,f(1)=6,f(6)=-2,f(-2)=3[/tex].

To find:

The value of [tex]\lim_{x\to 6^+}f(x)[/tex] and [tex]\lim_{x\to -2^-}f(x)[/tex].

Solution:

If a function f(x) is continuous at [tex]x=c[/tex], then

[tex]\lim_{x\to c^-}f(x)=f(c)=\lim_{x\to c^+}f(x)[/tex]

It is given that the function [tex]f(x)[/tex] is continuous. It means it is continuous for each value and the left-hand and right-hand limits are equal to the value of the function.

The function is continuous for 6. So,

[tex]\lim_{x\to 6^-}f(x)=f(6)=\lim_{x\to 6^+}f(x)[/tex]

[tex]\lim_{x\to 6^+}f(x)=f(6)[/tex]

[tex]\lim_{x\to 6^+}f(x)=-2[/tex]

The function is continuous for -2. So,

[tex]\lim_{x\to -2^-}f(x)=f(-2)=\lim_{x\to -2^+}f(x)[/tex]

[tex]\lim_{x\to -2^-}f(x)=f(-2)[/tex]

[tex]\lim_{x\to -2^-}f(x)=3[/tex]

Therefore, [tex]\lim_{x\to 6^+}f(x)=-2[/tex] and [tex]\lim_{x\to -2^-}f(x)=3[/tex].

Answer:

  270 miles

Step-by-step explanation:

For h hours of driving the distance d is covered:

  h = 2 +d/54

Solving for d, we find the distance covered in h hours is ...

  d = 54(h -2)

In 7 hours, the distance they traveled is ...

  d = 54(7 -2) = 270 . . . miles

They traveled 270 miles on the first day.

Answer:

$46.08

Step-by-step explanation:

Hi,

She gets 48 (1.35) when she sells 48 muffins. That equals 64.8.

But she pays 48 (.39) to make them. That equals 18.72.

64.8 - 18.72 = 46.08

She makes $46.08

Answer: [tex]m=\dfrac{-1}{3}, b=\dfrac{7}{3}[/tex]

Step-by-step explanation:

Given

Function is  [tex]f(x)=mx+b[/tex]

[tex]f(-2)=3[/tex]

[tex]\therefore 3=m(-2)+b\\\Rightarrow b-2m=3\quad \ldots(i)[/tex]

[tex]f(4)=1\\\therefore 1=4m+b\quad \ldots(ii)[/tex]

from (i) and (ii) we get

[tex]m=\dfrac{-1}{3}, b=\dfrac{7}{3}[/tex]
