Formula for Fahrenhelt temperature F=32+ 9/5C For C

Answer:

The answer is B.

Step-by-step explanation:

You have to use Pythogorean Theorem, c² = a² + b² where c is the hypotenuse and a,b is the side lengths :

[tex] {c}^{2} = {a}^{2} + {b}^{2} [/tex]

Let a = 40,

Let b = 9,

[tex] {c}^{2} = {40}^{2} + {9}^{2} [/tex]

[tex] {c}^{2} = 1600 + 81[/tex]

[tex] {c}^{2} = 1681[/tex]

[tex]c = \sqrt{1681} [/tex]

[tex]c = 41 \: units[/tex]

*Take note, hypotenuse will always be the longest length among the 3 lengths.

*Pythogorean Theorem can only applied in a right-angle triangle.

Answer:

Step-by-step explanation:

A) 4x + 6 = 2x - 12

Subtract 6 from both sides

4x + 6 - 6 = 2x - 12 -6

4x = 2x - 18

Subtract 2x form both sides

4x - 2x = 2x - 18 - 2x

2x = -18

B) 24 = 6x - 18

6x - 18 = 24

6x - 6*3 = 24

6(x - 3) = 24

Divide both sides by 6

[tex]\frac{6(x - 3)}{6}=\frac{24}{6}\\\\[/tex]

x - 3 = 4

The key word is "identical." If all students received identical packages, then Dr. Stein could have handed out 30 packages. He has a maximum of 30 notebooks to hand out, so if each package has one notebook, he can hand out 30 packages. Each of those 30 packages will also have 2 pencils and 10 erasers.

ANSWER: There are 30 packages maximum so he can have a maximum of 30 students.

Answer:

60

Step-by-step explanation:

Sum the parts of the ratio, 5 + 9 + 13 = 27 parts

Divide the amount of concrete by 27 to find the value of one part of the ratio.

324 ÷ 27 = 12 ← value of 1 part of the ratio , thus

5 parts = 5 × 12 = 60 ← cement

9 parts = 9 × 12 = 108 ← sand

13 parts = 13 × 12 = 156 ← gravel

To make 324 ft of concrete, we would need 60 ft of cement.

We have,

Given the ratio of cement, sand, and gravel as 5:9:13, we can consider the total number of parts in the mixture as 5 + 9 + 13 = 27 parts.

Now,

27 parts = 324 ft

Divide both sides with 27.

1 part = 324/27 ft

1 part = 12 ft

Now,

1 part = 12 ft

Multiply 5 on both sides.

5 parts = 5 x 12 ft

5 parts = 60 ft

Therefore,

To make 324 ft of concrete, we would need 60 ft of cement.

Answer:

Probably A, or 1

Step-by-step explanation:

You see, a square root function actually looks like a sideways parabola, just missing one side because of the domain of a square root. Now, the reason I can tell them apart is because our vertex is below the y-axis, and the only equation that has a negative y-intercept is the first one, or A.

Answer:

6.63 ft

Step-by-step explanation:

In this case we use pythagora's theorem which is

[tex]hyp^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]opp^{2}[/tex]

in this case, the hypotenuse (hyp) is the length of the ladder, the opposite (opp) is the height of the tree house and, the adjacent (adj) is the distance of the ladder's bottom to the base of the tree.

hpy = 12 ft

opp = 10 ft

adj = ?

substituting into the equation above, we have

[tex]12^{2}[/tex] = [tex]adj^{2}[/tex] + [tex]10^{2}[/tex]

144 = [tex]adj^{2}[/tex] + 100

144 - 100 = 44 = [tex]adj^{2}[/tex]

the image is shown below

adj = [tex]\sqrt{44}[/tex] = 6.63 ft

Answer:

The correct constraint is:

0 ≤ x ≤ 15

Step-by-step explanation:

The function given to us in the question is:

y = -2x² + 30x + 200

It is given that the function is at least 200, we can write is as:

-2x² + 30x + 200 ≥ 200  ⇒  Equation (i)

To find the constraint, replace ≥ sign with = sign and solve for x:

-2x² + 30x + 200 = 200

-2x² + 30x = 0

x(-2x + 30) =0

x = 0         ,      -2x + 30 = 0

x = 0         ,      -2x = -30

x = 0         ,       x = -30/-2

x = 0         ,       x = 15

So the end values of constraint are 0 and 15.

Take any value between 0 and 15 and substitute in equation (i) to see whether it satisfies the equation or not.

-2x² + 30x + 200 ≥ 200

Substitute x = 5 in the equation:

-2(5)² + 30(5) +200  ≥  200

-50 + 120 +200 ≥ 200

270 ≥ 200

As the equation satisfies. it means that the solution lies between 0 and 15, including the end values.

Hence.

0 ≤ x ≤ 15

Step-by-step explanation:

1. add 7/3x and 1/3x

2. subtract 5/3x because its the lowest number with a variable and you'll get 3/3x = 1

3. divide 3/3 from both sides (3/3) equals 1, so its 1/1 which is 1

4. x=1

Answer:

A.

Step-by-step explanation:

1 radian = 180/π

So

Multiplying both sides by 25π/18

We'll get,

25π/18 (r) = (180/π)×(25π/18)

= (180×25)/18

= 10×25

Answer:

A). Surface area = 222 cm²

Volume = 180 cm³

B). Surface area = 375 cm²

Volume = 360 cm³

C). % increase in surface area = 67.57%

% increase in volume = 100%

Step-by-step explanation:

In the figure attached base of a prism has been given.

A). Surface area of the prism = (Perimeter of the base of the prism) × height + 2(area of the base)

Perimeter of the base = 5 + 3 + 2 + 2 + 2 + 3 + 5 + 8

                                       = 30

Area of the base = 8×5 - 2×2 = 36 cm²

Surface area of the prism = 30×5 + 2×(36)= 222 cm²

Volume of the prism = volume of the bigger prism - volume of the smaller prism cut off

                                  = 8×5×5 - 2×2×5

                                  = 200 - 20

                                  = 180 cm³

B). Surface area of the prism if it's height is 10 cm,

Surface area = 30×10 + 2×(36) = 372 cm²

Volume of the prism = 8×5×10 - 2×2×10

                                   = 400 - 40

                                   = 360 cm³                                      

C). Increase in surface area = 372 - 222 = 150 cm²

% increase in the surface area = [tex]\frac{150}{222}\times 100[/tex] = 67.57%

Increase in volume = 360 - 180 = 180 cm³

% increase in volume = [tex]\frac{180}{180}\times 100[/tex] = 100%
