How many prime numbers have squares between 100 and 300?

Answer:

2 quadrant

Step-by-step explanation:

i think

Answer:

Quadrant 2...

Answer:

~73.68

Step-by-step explanation:

In the right triangle with one angle = 45 deg

=> Isosceles right triangle

=> a = b = hypotenuse/sqrt(2) = (12sqrt(2))/sqrt(2) = 12

In other right triangle with 3 sides are a, c, and d, we have:

sin (30 deg) = a/d

=> d = a/sin(30 deg) = 12/(1/2) = 12 x 2 = 24

Othwise, cosine (30 deg) = c/d

=> c = d x cos(30 deg) = 24 x sqrt(3)/2 = 12sqrt(3)

=> The perimeter of the biggest triangle is calculated by:

P = 12sqrt(2) + b + c + d = 12sqrt(2) + 12 + 12sqrt(3) + 24 = ~73.68

Answer:

1/5 = 0.2

Step-by-step explanation:

(0,3) and (5,4)

average rate of change is slope

formula for slope =  [tex]\frac{y2-y1}{x2-x1}[/tex]

so [tex]\frac{4-3}{5-0} = \frac{1}{5}[/tex]

Answer:

$713.8

Step-by-step explanation:

14%of 860 = 120.4

3% of 860 = 25.8

so, subtract the sum of the above 2 values from 860.

860 - (120.4+25.8) = 860-146.2 = 713.8

Hope this helps

Answer:

$713.008

Step-by-step explanation:

Answer:

I will answer this in English.

a) here you written 208 = (2^6)*3, while in the table you can see 5 times the number 2 and 2 times the number 3, this means that:

208 = 2^5*3^2

then we would have:

√208 = √(2^5*3^2) = 3*2*√2 = 6*√2

b) This time is correct that:

1568 = 2^5*7^2

but the simplification in the square root is not correct. (√(2^5) is not equal to 2^2)

as √(2^5*7^2) = √(2*2^4*7^2) = 2^2*7*√2 = 4*7*√2 = 28*√2

Answer:

Correct option: second one

Step-by-step explanation:

To find the composite function r(V(t)) (radius of the ball in relation to time being inflated), we just need to use the value of the equation V(t) in each value of V in the function r(V).

[tex]V(t) = 10t[/tex]

[tex]r(V)=\sqrt[3]{3V/4\pi}[/tex]

[tex]r(V(t))=\sqrt[3]{3V(t)/4\pi}[/tex]

[tex]r(V(t))=\sqrt[3]{3*10t/4\pi}[/tex]

[tex]r(V(t))=\sqrt[3]{30t/4\pi}[/tex]

Correct option: second one

Answer:

Isosceles trapezoid

Step-by-step explanation:

The figure will look like one large triangle on the outside and four smaller triangles on the inside. you are only concerned with the inside triangle that is pointing to the line FH. Since XY and FH are parallel and the distance between FX and YH are equivalent (the midpoints of each side should be the same for all three sides of the larger triangle) the shape FXYH is an isosceles trapezoid.

Answer:

trapezoid

Answer:

1/3

Step-by-step explanation:

[tex]\sqrt[4]{4x+10}[/tex] = 4x+10 ^1/4

[tex]\sqrt[4]{9+7x}[/tex]= 9+7x^1/4

Since they are under the same root, you can combine them under the root.

Then you change the +/- sign of one side of the equation to move to the other side of the equation.

To get....[tex]\sqrt[4]{-3x+1}[/tex]=0

^4 both sides to get..

-3x+1=0

Move 1 to the other side...

-3x=-1

divide both sides by -3

x=1/3

Answer:

b => base  => 40 cm

h => altitude => 30 cm

A = h*b/2

h=b-10

600=(b-10)b/2

600 = (b^2-10b)/2

1200=b^2-10b

b^2-10b-1200=0

(b-40)(b+30)=0

b=40 cm

h=b-10 = 40-10=30

Answer:

360 cm^2

Step-by-step explanation:

If you move the triangle to the right, you can see it fits perfectly into the right side of the parallelogram. Therefore, we have a rectangle, with width 20 and height 18. 18x20=360.

Answer:

The length is 35 inches and the width is 15 inches.

Step-by-step explanation:

First work of the real length of the field. Given is the ratio of drawing to original and the dimensions of the drawing. so in real life the lawn measures 70 inches in length and 30 inches in width.

Now, we have to divide this in the ratio 1:2, which gives

The length of 35 inches and the width of 15 inches.

Hope this helps

Answer:

At x = -2 the graph of this polynomial will touch the x-axis.

Step-by-step explanation:

Recall the behavior difference between power functions of even and odd power. Odd powers are associated with the crossing of the x-axis, while even powers are associated with "touching" of the x axis.

in this cases, since they give you the function in factor form, the actual roots (x-values where the function adopts value zero) of the function are evident :

[tex]f(x)=(x-5)^3\, (x+2)^2[/tex]

It has a root at x = 5 [notice that at such x-value the factor (x-5) becomes zero], and this root is of multiplicity "3" (given by the power associated with the binomial factor for this root)

and has another root at x = -2  [notice that at such x-value the factor (x+2) becomes zero], and this root is of multiplicity "2" (given by the power associated with the binomial factor for it)

It is just the second root analyzed the one that shows an even power (2) associated to its binomial factor, and therefore it is at x= -2 that the graph of this function will show as "touching" the x axis.

Answer:

I would need the radius of the cone to answer this completely, bit I can get you super close and explain it.

Step-by-step explanation:

The formula for a cone is

[tex]\pi \times r {}^{2} \times \frac{h}{3} [/tex]

From there, I started plugging in numbers. I set this equation equal to 540pi because both if them are the volume, so they are equal and I simplified as much as I could from there. First off, the pi cancel each other out since they're on both sides of the equation. From there you have this equation:

[tex]r {}^{2} \times \frac{h}{3} = 540[/tex]

Then, I multiplied both sides by 3 to get rid of the fraction on the left side of the equation:

[tex]r {}^{2} h = 1620[/tex]

Finally, I got rid of the "squared" by putting a square root over both sides if the equation, getting this:

[tex]r \times h = 40.249[/tex]

If I knew the radius. I could get the answer by dividing both sides by the radius.

Good luck!

Answer:

[tex]\fbox{\begin{minipage}{12em}52 percent and 50 percent \end{minipage}}[/tex]

Step-by-step explanation:

Given (as shown in graph):

The results of rolling a number cube (a die) 50 times.

Rolling 1: 10 times

Rolling 2: 4 times

Rolling 3: 8 times

Rolling 4: 11 times

Rolling 5: 8 times

Rolling 6: 9 times

Solve for:

The probability of rolling an odd number (1, 3, 5).

Solution:

Step 1: Define the formula for calculating the probability

P = number of elements/total number of elements

Step 2: Perform the calculation

1) Theoretically, a fair die of 6 sides would give the equal chance to obtain 1, 2, 3, 4, 5, 6.

According to the formula in step 1, the number of elements in both cases are the same (odd: 1, 3, 5 => 3 elements, even: 2, 4, 6 => 3 elements, the total element is 1, 2, 3, 4, 5, 6 => 6 elements).

=> P(obtain odd number theoretically) = P(obtain even number theoretically) = 50%

2) Experimentally, apply the formula in step 1, we have:

The number of elements = Times of rolling 1 + Times of rolling 3 + Time of rolling 5 = 10 + 8 + 8 = 26

The total number of rolling: 50

=> P(obtain odd number in experiment) = 26/50 = 0.52 = 52%

Hope this helps!

Answer:

78 square ft.

The answer is 75 ft

explanation

12ft x 2.5ft = 30ft

12ft x 2ft = 24ft

12ft x 1.5ft = 18ft

1.5ft x 2ft = 3ft

30 + 24 + 18 + 3 = 75
