Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

10x+24 = 6x+72

10x - 6x = 72 - 24

4x = 48

x = 12

Answer:

144

Step-by-step explanation:

10x+24=6x+72

-6x          -6x

4x+24=72

     -24  -24

4x=48

/4   /4

x=12

<A=10(12)+24

<A=120+24

<A=144

Using an exponential function, it is found that 0.08 ml of the will be in the body in 30 hours.

The amount of a decaying substance is modeled by an exponential function in the following format:

[tex]A(t) = A(0)e^{-kt}[/tex]

In which:

In this problem, the half-life is 6 hours, which means that [tex]A(6) = 0.5A(0)[/tex], and this is used to find k.

[tex]A(t) = A(0)e^{-kt}[/tex]

[tex]0.5A(0) = A(0)e^{-6k}[/tex]

[tex]e^{-6k} = 0.5[/tex]

[tex]\ln{e^{-6k}} = \ln{0.5}[/tex]

[tex]-6k = \ln{0.5}[/tex]

[tex]k = -\frac{\ln{0.5}}{6}[/tex]

[tex]k = 0.11552453009[/tex]

Hence:

[tex]A(t) = A(0)e^{-0.11552453009t}[/tex]

2.5 ml injection, hence [tex]A(0) = 2.5[/tex]

After 30 hours, we have to find A(30), hence:

[tex]A(t) = 2.5e^{-0.11552453009t}[/tex]

[tex]A(30) = 2.5e^{-0.11552453009(30)}[/tex]

[tex]A(30) = 0.08[/tex]

0.08 ml of the will be in the body in 30 hours.

Answer:

180 cm

Step-by-step explanation:

Number of trials per team = 3

Distance per trial for team D's car is the same for each trial, let distance = x

Distance per trial for team C's car is 1cm farther than team D's distance and the same for each trial, hence, distance = x + 1 per trial

Total distance traveled by C = 543 cm

This means :

(x + 1) + (x + 1) + (x + 1) = 543

3x + 3 = 543

3x = 543 - 3

3x = 540

x = 540 / 3

x = 180

Hence, distance traveled per trial for team D's car = x = 180 cm

No,

[tex]9e + 2(e + 5) = 11e + 10[/tex]

And 11e + 10 is not equivalent to 11e + 5

Answer:

No, its not.

9e + 2(e+5)

= 9e + 2e + 10

= 11e + 10

---> 9e+2(e+5) when simplified gives 11e + 10.

---> Therefore, its not equal to 11e + 5

Answer:

A

Step-by-step explanation:

since it is on sale for 27%, multiply $28 by 70% (0.7) to find the total amount of money the shirt costs now that it is on sale (since it's on sale for 30% off)

$28*0.7=$19.60

Answer:

$19.60

Step-by-step explanation:

First, find 30% of $28.  :)

To do this, multiply 28 by 0.3. (30% is the same thing as 3/10 or 0.3)

28 x 0.3 = 8.4.

30% of 28 is 8.4.

Next, subtract $8.4 from $28. (Shirt on sale for 30% off)

28 - 8.4 = $19.60

Have a great day!

Answer:

Z'(9, - 1)

Step-by-step explanation:

For a 90 degree counterclockwise rotation about the origin,

The original coordinates of point P (x,y) will now be positioned as P' (-y,x).

Hence, given :

Triangle XYZ with X(-7,-9), Y(-10,-3), and Z(-1,-9)

The new position of Z denoted as Z' will be :

Z(-1, - 9) ; X = - 1 ; y = - 9

-y = - - 9 = 9

x = - 1 will remain as - 1

Z(-1, - 9) - - - > Z'(9, - 1)

Answer:

Supplementary angles add to 180 degrees. So of the measure of the angle is x, the measure of its supplement is 2x. Angle = 60, supplement = 120

Step-by-step explanation:

Answer:

139.5º

Step-by-step explanation:

The sum of supplementary angles is 180º

s + 40.5 = 180

Subtract 40.5 from both sides

s = 139.5º

Answer:

[tex]A=830\ ft^2[/tex]

Step-by-step explanation:

Given that,

The length of one base is 37 feet, and the length of the other base is 46 feet. The height is 20 feet.

We need to find the area of this section of the deck that is shaped like a trapezoid.

The area of a trapezium is given by :

[tex]A=\dfrac{a+b}{2}\times h[/tex]

a = 37 ft, b = 46 ft and h = 20 ft

Put all the values,

[tex]A=\dfrac{37+46}{2}\times 20\\\\A=830\ ft^2[/tex]

So, the area of this section of the deck is equal to [tex]830\ ft^2[/tex].

125 is an outlier

125 changes the mean by 23 points (from 375 to 352)

Step-by-step explanation:

an outlier is 1.5 times the IQR

the InterQuartile Range of this set of data is 400-350 or 50

Answer:

The answer is D, sqrt(41)in.

Step-by-step explanation:

The question is asking about the hypotenuse L. You can get that by using the Pythagorean Theorem( a^2+B^2=C^2). You can get the bottom length of the triangle by dividing 8 by 2, because the triangle is made from the top point of the pyramid. You can there do 5^2+4^2, which is 41. You then need to take the square root of that, or [tex]\sqrt{41}[/tex].
