There's a roughly linear relationship between the length of someone's femur (the long leg-bone in your thigh) and their expected height. Within a certain population, this relationship can be expressed using the formula h=2.35f+54.7h, where h represents the expected height in centimeters and ff represents the length of the femur in centimeters. What is the meaning of the ff-value when h=149h

[tex]0,4(5x-15)=2,5(x+3)\\\\2x-6=2,5x+7,5\\\\2x-2,5x=7,5+6\\\\-0,5x=13,5 \ \ /\cdot(-2)\\\\\huge\boxed{x=-27}[/tex]

Answer:

Answer:

x=−27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

0.4(5x−15)=2.5(x+3)

(0.4)(5x)+(0.4)(−15)=(2.5)(x)+(2.5)(3)(Distribute)

2x+−6=2.5x+7.5

2x−6=2.5x+7.5

Step 2: Subtract 2.5x from both sides.

2x−6−2.5x=2.5x+7.5−2.5x

−0.5x−6=7.5

Step 3: Add 6 to both sides.

−0.5x−6+6=7.5+6

−0.5x=13.5

Step 4: Divide both sides by -0.5.

−0.5x

−0.5

=

13.5

The total cost of the camera is $73.84

Since Vijay bought a camera that was marked down 80% from the original price of $355, then the amount paid will be:

= $355 - (80% × $355)

= $355 - (0.8 × $355)

= $355 - $284

= $71

Since there is a 4% sales tax, then the total amount paid will be:

= $71 + (4% × $71)

= $71 + (0.04 × $71)

= $71 + $2.84

= $73.84

The total cost of the camera is $73.84

Answer:

D

Step-by-step explanation:

We can cross off a because it is impossible to have negative of a material.

Now lets get into the System of equations. First subtract both of them to have one common variable(we will find the second one later)

- P + N = 134

- P + 3.1N = 241.10

2.1N = 107.1

107.1/2.1 = 51

Now we know that n = 51

lets substitute,

P + 51 = 134

P = 83

Lets check

83  + 51 = 134

Answer: if the width was not effected then the width is still 24 inches

if the area stayed the same, then

find area

area=legnth times width

288=12 times 24

so the new height./legnth =2

288=2 times width

Answer:

∣x + 7.5∣ = 2.5

Step-by-step explanation:

∣x + 7.5∣ = 2.5

x + 7.5 = -2.5  OR  x + 7.5 = 2.5

   -7.5      -7.5             -7.5     -7.5

--------------------        ----------------------

x = -10                         x = -5

As you can see, the equation ∣x + 7.5∣ = 2.5, satisfies both of the x values, x=-10 and x=-5.

The absolute value equation that has solutions x= -10 and x = -5 is             | x + 7.5 | = 2.5.

Absolute value function is always positive |x| = a implies  x = a Or - x = - a

According to the given question we have to write a equation we have to write an absolute value equation that has solution x = -10 and x = - 5.

Let the absolute value be ∣x + 7.5∣ = 2.5.

∴ x + 7.5 = 2.5 OR - ( x + 7.5 ) = 2.5

x + 7.5 = 2.5

x = 2.5 - 7.5

x = - 5.

OR

- ( x + 7.5 ) = 2.5

- x - 7.5 = 2.5

- x = 2.5 + 7.5

- x = 10

x = - 10.

triangles unfold into a 180 degree angle so...

Step-by-step explanation:

Alright so the two dashes in a line means they are equivalent so if I only give one final answer use it for both...

D: 180-52=128 now divide by two since equal angles so 64 degrees for the angles

E: 180-90=90, 90/2 so 45 degrees for those angles

F: okay interesting 180-130= 50 degrees so that's the inside angle there for x and y so to find z its 180- 100 which is 80 x&y is 50 while z's 80

G: 180-36=144 divide that by two and viola 72 is the answer

H: the angle of 86 is correct since mirrored. so x is 86. now for the unlisted angle 180-124= 66 so to find y 86+66=152 so 180-152=28. So x=86 y=28 and the unlisted is 66.

The arc is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × [tex]\frac{225}{360}[/tex] ( r is the radius )

given diameter = 24 then r = 24 ÷ 2 = 12

arc = 2π × 12 × [tex]\frac{5}{8}[/tex]

Answer:

The next term is 42

Step-by-step explanation:

Let's use Arithmetic Progression

a₁ = - 3

a₂ = 12

a₃ = 27

Now,

The Formula of Common Difference d is

d = a₂ - a₁

= 12 - (-3)

= 12 + 3

d = 15

d = a₃ - a₂

= 27 - 12

d = 15

Here, the common difference is same

aₙ = aₙ₋₁ + d

a₄ = a₄₋₁ + 15

a₄ = a₃ + 15

a₄ = 27 + 15

a₄ = 42

So, The next term is 42
