Answer:

Look below

Step-by-step explanation:

-x*3x*2x=6x^3

-6x^3<900

-(cube root both sides)

-6x<9.654893846

-divide by 6

-x=1.609148974

And since 1.609148974 is less than 5, that means that X<5 is correct and hence proved

For given cuboid, x < 5

"It is a three-dimensional geometric structure that has six rectangular faces, twelve edges and eight vertices."

V = l × w × h

where, l: length of the cuboid

w: width of the cuboid

h: height of the cuboid

For given example,

We have been given the total volume of the cuboid is less than 900 cm^3

⇒ V < 900 cm³

the length of the cuboid (l) = 3x

the width of the cuboid (w) = 2x

the height of the cuboid (h) = x

Using the formula of the volume of the cuboid,

⇒ V < 900

⇒ l × w × h < 900

⇒ (3x) × (2x) × (x) < 900

⇒ 6x³ < 900

⇒ x³ < 150

⇒ x < 5.3

⇒ x < 5

Therefore, for given cuboid, x < 5

Answer:

4*6=24     answer:6

any other number would be less or more

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

4 x 6 is 24 and 4 x 7 is 28. 26 is between 24 and 28, so got to 24 since that is less than 26. 4 x 6 gets you 24, so 6 is your answer.

Answer:

y = (10 * 0.2) ^ x

Y = (2)^x

Y =  2^x + 10

6.5 hours

Step-by-step explanation:

Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.

Answer:

172 is the 34th term

Given :

Base area of Ms. Jones decorative pyramid = 6 inches²

Height of the decorative pyramid = 15 inches

We know that :

[tex]\color{hotpink}\tt \: volume \: of \: a \: triangular \: pyramid\color{plum} \tt \: = \frac{1}{3}Bh [/tex]

Volume of the decorative pyramid :

[tex] =\tt \frac{1}{3} \times 15 \times 6[/tex]

[tex] =\tt \frac{15 \times 6}{3} [/tex]

[tex] =\tt \frac{90}{3} [/tex]

[tex]\color{plum} =\tt 30 \: {inches}^{3} [/tex]

Therefore, the volume of the decorative pyramid with Ms. Jones = 30 inches³

Answer:

The answer is (3,-2)

Step-by-step explanation:

[tex] \frac{1}{3} x - 3 = - 2x + 4 \\ \frac{1}{3} x + 2x = 7 \\ \frac{7}{3} x = 7 \\ x = 3 \\ then \: \\ y = - 2[/tex]

Answer:

f = 4n

f = n+27

Fred is 36 years old and Nathan is 9 years old.

n = 9

Step-by-step explanation:

Answer:

Step-by-step explanation:

Ooh I love these type of problems

Okay, here we go :

f = Fred and n = Nathan

  f = 4n

  f = n + 27

Above are the two equations (the words translated into algebra)

Now you can solve using substitution (any method works, but substitution is easiest for this problem)

4n = n + 27

3n = 27

n = 9

Since n = 9 substitute n into either equation

f = 4 * 9

f = 36

Fred is 36 and Nathan is 9

Answer:14.4

Step-by-step explanation:

Answer:

C. 14 feet

Step-by-step explanation:

THIS IS TO FIGURE OUT THE TRIANGLE

You have to do the Pythagorean Theorem, which is a² + b² = c²

Since h is the entire piece of wood including the additional 2 feet, I will use m as variable for triangle

Fill in for variables: 5² + m² = 13²

Simplify: 25 + m² = 169

Subtract 25 from both sides: m² = 144

Square root both sides to get m alone: m = 12

Now, you have to add the additional 2 feet above the triangle: 12 + 2 = 14

Therefore, h=14

Answer:

12

Step-by-step explanation:

The only answer that makes sense. If you use pythagorean theorem which is a^2+b^2=c^2, and c is the hypotenuse, which is the slanting side, you do this

12^2+5^2=13^2?

144+25=169

169=169

it checks!

Answer:

c=l/--a^2+b^2=l/--45^2+20^2≈49.24429

Step-by-step explanation:

l/-- mean square root

^ means squared/ exponent

Answer:

Since they're asking you to find the missing sides "y" and "x" here's what you need to do....

Step-by-step explanation:

1) This is the 45-45-90 Triangle.

2) y = 20 becasue this is an isocelese triangle - meaning a triangle that has 2 sides of equal lengths!

3) in order to find x (which is the hyptoneus) you have to do

       [tex]\sqrt{2}[/tex] * leg (use on of the legs)

    =  [tex]20\sqrt{2}[/tex]

also I think 45 degrees is there just to throw you off. And I'm pretty positive this is the correct answer, and i'm 100% sure that y = 20 is correct!

I’m pretty sure it’d be y = -x - 2

lmk if it’s wrong.

Answer:

a

Step-by-step explanation:

formula for cos theta is ration of adjacent side to hypotenuse side

so, 28 is adjacent side.

and 53 is hypotenuse side.

Thats why the ans is A

The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is A.

The trigonometric function gives the ratio of different sides of a right-angle triangle.

[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\[/tex]

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

The value of cosθ can be written as,

Cosθ = Base / Hypotenuse

Cosθ = 28/53

Hence, the correct option is A.
