Can someone pleasee help its so confusing for me

Answer:

r = 1

Step-by-step explanation:

Answer:

volume of cone=424cm³

height(h)=5cm

radius (r)=?

Step-by-step explanation:

we have

volume of cone=1/3(πr²h)

424=1/3(22/7×r²×5)

424×3=15.71r²

r²=1272/15.71

r=√80.9=8.9=9cm

Answer:

Angle x = 38°

Step-by-step explanation:

It is important to note that:

Two angles are called supplementary when their measures add up to 180 degrees.

Angle x and y are supplementary

Angle y = 142°

Hence,

Angle x = 180° - 142°

Angle x = 38°

Answer:

1.5 inches. you take 450 and divide it by 300

Answer:

the very first one 8.62<8.623

Answer and Step-by-step explanation:

Use the Pythagorean Theorem to solve for the height.

[tex]a^{2}+ b^{2}= c^{2} \\\\\\4^{2} + b^{2} = 5^{2}\\\\\\16 + b^{2} = 25\\\\\\b^{2} = 9\\\\\\b = 3[/tex]

The height of the triangle is 3.

Now we can solve the shapes in  the trapezoid.

4 times 3 = 12 (Rectangle)

[tex]\frac{4 * 3}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6 (Triangle)

12 + 6 = 18 (Trapezoid)

The area of the trapezoid is 18 [tex]units^{2}[/tex].

Answer:

3 years

Step-by-step explanation:

To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.

Using this formula

A=P(1+r/n)^nt

Let plug in the formula

14,100=8000(1+0.05)^t

(1+0.05)^t=14,100/8000

(1+0.05)^t=1.7625

1.05^t=1.7625

t=log(1.7625)/log(21/20)

t=0.246/0.021189

t=11.6

Therefore how long must the person leave the money in the bank until it reaches 14100 dollars is: 11.6.

Answer:

x = -4

Step-by-step explanation:

Since the slope is undefined, the line is a vertical line.  All vertical lines have an equation x = k.  In your problem k = -4, so the equation of the line is x = -4

Answer:

83.3%

Step-by-step explanation:

The probability of rolling a 3 on a 6-sided dice is 1/6

Since you don't want a three, there's a 5/6 chance of not rolling a 3

5/6 (use calculator and divede 5 by 6) = 0.833333 (move decimal 2 to the right) = 83.3%

Therefore, the most reasonable answer would be C, 83.3%

Answer:

g+4=12

Step-by-step explanation:

Since the painter used 4 of the 12 gallons, the painter now has 8 gallons, so g=8.

The equation g+4=12 represents this because if we solve it by isolating g then we get that g=8.

Answer:

[tex]x=17[/tex]°

Step-by-step explanation:

Because the diagonal lines are marked with arrows, we know that they are parallel. The two angles that are marked with measures are same-side interior angles. Same-side interior angles of parallel lines are supplementary, meaning that the sum of their measures is [tex]180[/tex]°.

Now, with all of this information, we can set up the following equation and solve for [tex]x[/tex]:

[tex]115+4x-3=180[/tex]

[tex]112+4x=180[/tex] (Simplify LHS by combining like terms)

[tex]112+4x-112=180-112[/tex] (Subtract [tex]112[/tex] from both sides of the equation to isolate [tex]x[/tex])

[tex]4x=68[/tex] (Simplify)

[tex]\frac{4x}{4}=\frac{68}{4}[/tex] (Divide both sides of the equation by [tex]4[/tex] to get rid of [tex]x[/tex]'s coefficient)

[tex]x=17[/tex]° (Simplify)

Hope this helps!

Answer:

66.59

Step-by-step explanation:

The surface area can be calculated as follows

= a^2 + 2a √ a^2/4 + h^2

= 4^2 + 2(4) √ 4^2/4 + 6^2

= 16 + 8 √16/4 + 36

= 24 √ 4+36

= 24 √40

= 66.59

Answer:

m<X = 27 degrees

Step-by-step explanation:

From △VWX, since WX = XV, this mean that the triangle is isosceles

The base angle of an isosceles triangle are equal hence <W = <X

Since <W = 27 degrees, hence m<X = 27 degrees

Answer:

x = 38.2°

Step-by-step explanation:

sin 27°  =    x°  

    11             15

15 · (sin 27°) = 11 · x°

cross-multiply:

6.81 = 11x

6.81 / 11 = x

x = 0.619

sin^-1 (0.619) = 38.2°

Answer:

Three perpendicular bisectors are required

Step-by-step explanation:

A perpendicular bisector of a line segment is a line that cuts the line segment at a 90° angle, dividing it into two equal halves.

In this example, one bisector produces two equal parts of the segment

two bisectors produce three segments and three bisectors, four segments as shown in the diagram.

Perpendicular bisectors are constructed using a compass and a pencil, you can check out how to construct one, it is pretty interesting.

Data for the question :

1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2

Answer:

Julie is Incorrect

Step-by-step explanation:

Given the data:

1 3/4, 2 1/2, 2, 2 3/4, 1, 1 3/4, 1 1/4, 3, 3 1/4, 3 3/4, 2, 2

The least amount of time spent is : 1

The most amount of time spent is 3 3/4

According to Julie ; the most amount of time spent is equal to 1 1/2 the least amount of time spent.

That is,

3 3/4 = 1 * 1 1/2

3 3/4 = 15/4

1 * 3/2 = 3/2

Hence, she is incorrect ;

15/4 ≠ 3/2
