Answer:

THE 2 ONE

Step-by-step explanation:

Answer:

The interval with the most amount of dots has the greatest number of boxes.

Step-by-step explanation:

Because each dot represents equal number of box(es), the interval with the most number of dots has the greatest number of boxes.

Answer:

35.92 m

Step-by-step explanation:

To have a better comprehension of the problem, we can draw it as in the image attached.

If we use the tangent relation in both triangles, we have:

tangent(35) = h/x

tangent(20) = h/(150-x)

From the first equation, we have:

x = h/tangent(35) = h/0.7

From the second equation, we have:

0.364 = h / (150 - h/0.7)

54.6 - 0.52h = h

1.52h = 54.6

h = 35.92 m

i'd say it would be 4 over 1         4/1    so you go up 4 and to the right 1 if they were negative then it would be the oposite way around.

Answer:

87 feet

Step-by-step explanation:

Two of the sides here are unknown. The one on the leftmost side is equal to 9, since on the other side it also has a length of 9 feet. The section on the top right has a length of 30-9-9=12 units. Adding all of these values together now, you get a total perimeter of:

30+9+12+9+9+9+9=87 feet

Hope this helps!

Answer:

The perimeter of this shape is 87 ft.

Step-by-step explanation:

Given that all side lengths are added together in order to find perimeter. So the perimeter is :

[tex]perimeter = 9 + 9 + 9 + 12 + 9 + 30 + 9[/tex]

[tex]perimeter = 45 + 30 + 12[/tex]

[tex]perimeter = 87 \: feet[/tex]

Firstly let's find hypotenuse(let it will be "n" of smaller triangle

Let use Pythagorean theorem

[tex]a^{2} + {b}^{2} = {n}^{2} \\ {20}^{2} + {10}^{2} = {n}^{2} \\ n = \sqrt{500} [/tex]

Now we need to find hypotenuse(x) of bigger triangle

[tex] {c}^{2} + {n}^{2} = {x}^{2} \\ {9}^{2} + { \sqrt{500} }^{2} = {x}^{2} \\ x = \sqrt{581} [/tex]

The value of x must be rounded to 1 DP, so

[tex] \sqrt{581} = 24.1039... \\ \sqrt{581} \simeq \: 24.1[/tex]

Answer: x=24.1

Answer:

1.3

Step-by-step explanation:

BC is the distance between B and C.

BC = x − (-0.4)

BC = x + 0.4

AB is the distance between A and B.

AB = -0.4 − (-1.25)

AB = -0.4 + 1.25

AB = 0.85

Substitute into the equation.

BC = 2AB

x + 0.4 = 2(0.85)

x + 0.4 = 1.7

x = 1.3

Answer:

x=1.3

Step-by-step explanation:

AB=(-0.4-(-1.25))=1.25-0.40=0.85

BC=2AB=2×0.85=1.70

x=-0.4+1.7=1.3

Answer:

1 / (99 - 40x).

Step-by-step explanation:

The whole of g(x) is input to f(x), so:

we replace the x in f(x) by g(x).

f(g(x)) =  1 /  [8(12 - 5x) + 3]

=  1 /( 96 - 40x + 3)

= 1 / (99 - 40x).

Answer:

m=3

Step-by-step explanation:

Answer:

.6

Step-by-step explanation:

Ratios are just another way of writing fractions. 3:5 is just 3/5 which is .6 or 60%

Answer:

Line: y = Mx + b, passes (0, 1) => M*0 + b = 1 => b = 1

Line: y = Mx + 1, pass (2, 4) => 2M + 1 = 4 => M =3/2

=> Line: y = (3/2)x + 1

Answer:

Step-by-step explanation:

In the Fibonacci sequence In mathematics, the Fibonacci numbers, commonly denoted [tex]Fn[/tex], form a sequence, called the Fibonacci sequence, such that each number is the sum of the two preceding ones, starting from 0 and 1.

Given data

First term= n

second term = 3n

third term = 4n

According to Fibonacci sequence the fourth term is

[tex]F4= F2 + F3\\F4=3n+ 4n= 7n[/tex]

the Fifth term is

[tex]F5= f3 + f4\\f5= 4n+7n= 11n[/tex]

hence  the sixth term is

[tex]F6= F4+F5\\ F6= 7n+11n= 18n[/tex]

Answer:

enlargment and 6.4 feet per inch

Step-by-step explanation:

i got it right on mine

The blank words are:

Enlargement and 6.4.

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

Given:

A company plans to scale its logo and place it on a billboard so that drivers and pedestrians can see it easily from the ground.

The original logo is a square with sides of 1.25 inches.

After scaling,

the local must have a perimeter of 32 feet.

This action is called enlargement,

and the scale factor is,

= (32/4) / 1.25

= 8 / 1.25

= 6.4.

Therefore, the scale factor is 6.4.

Answer:

1.5 hours

Step-by-step explanation:

Divide 514 by 338 to get 1.5207 and round it to 1.5 because we are working with time

We have been given image of a circle. We are asked to find the measure of angle WTV.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle WTV is inscribed angle to arc WV. So measure of angle WTV will be half the measure of arc WV.

[tex]\angle WTV=\frac{1}{2}\widehat{WV}[/tex]

[tex]\angle WTV=\frac{1}{2}\cdot 90^{\circ}[/tex]

[tex]\angle WTV=45^{\circ}[/tex]

Therefore, the measure of angle WTV is 45 degrees and 2nd option is the correct choice.

Answer:

24 ft^3

Step-by-step explanation:

Cylinder:

Volume = (pi)r^2h

Cone:

Volume = (1/3)(pi)r^2h

When using r and h for both a cylinder and a cone, the only difference is the factor of 1/3 for the volume of the cone.

A cone with the same radius and height as a cylinder has 1/3 the volume of the cylinder.

volume of cylinder = 72 ft^3

volume of cone = (1/3) * 72 ft^3 = 24 ft^3

Answer:

The volume of cone is 24 ft³

Step-by-step explanation:

Given that volume of cylinder = 72 ft³

Volume of cylinder = πr²h

Volume of cone = [tex]\frac{1}{3}[/tex][tex]\pi[/tex]r²h

Volume of cone = volume of cylinder/3

= 72/3

= 24 ft³

Answer:

d. g36

Step-by-step explanation:

The solution is, g^36 power is equivalent to the expression (g-12)-3.

An exponent refers to the number of times a number is multiplied by itself. For example, 2 to the 3rd (written like this: 23) means: 2 x 2 x 2 = 8. 23 is not the same as 2 x 3 = 6. Remember that a number raised to the power of 1 is itself.

here, we have,

given expression is,

g^(-12)(-3)

=g^(12*3)

=g^36

Hence, The solution is, g^36 power is equivalent to the expression (g-12)-3.
