Answer:

25n + 600 > 1400 ​

Step-by-step explanation:

The density of the lime is 1.38 g/cm^3.

Remember that the density is given by the quotient between mass and volume.

Here, the lime is a sphere with a radius of 2.5 cm, remember that the volume of a sphere of radius R is given by:

V = (4/3)*pi*R^3

So our lime has a volume:

V = (4/3)*3.14*(2.5 cm)^3 = 65.42 cm^3

And the mass is M = 90 grams, then the density is:

D = M/V = (90 g)/(65.42 cm^3) = 1.38 g/cm^3

Its Simple All the angles in a triangle adds up to 180°

Step-by-step explanation:

∠A + ∠ B + ∠C = 180° NO matter what. You can also use this in inverse If you have two out of three angles then you can add the two angles you have and subtract the from 180 to get the measurement of the 3rd angle.

Answer:

54 and here is why..

Step-by-step explanation:

In order to calculate the surface are of the prims, you have to calculate the area of each face of the prism, also you have to remember the different formulas to calculate the areas:

Rectangle will be (Length x Width) and

Triangle will be (Base x Height / 2)

SOOO, You just have to insert the values into formulas:

Rectangle1 = 4 x 3.5

Rectangle1 = 14

Rectangle 2 = 5 x 3.5

Rectangle 2 = 17.5

Rectangle 3 = 3 x 3.5

Rectangle 3 = 10.5

Triangle 1 = 4 x 3 / 2

Triangle 1 = 6

Triangle 2 = 4 x 3 / 2

Triangle 2 = 6

SOoo again, if you add all the faces, you get the surface area of the prims:

14+17.5+10.5+6+6=54

Answer:

[tex]\sf y \leq \dfrac34x[/tex]

Step-by-step explanation:

Choose 2 points on the line:  (0, 0) and (4, 3)

[tex]\sf slope=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-0}{4-0}=\dfrac34[/tex]

point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

[tex]\implies \sf y-0=\dfrac34(x-0)[/tex]

[tex]\implies \sf y=\dfrac34x[/tex]

Solid line : ≤ or ≥

Dashed line: < or >

Therefore as the line is solid, and the shading is below the line,

[tex]\implies \sf y \leq \dfrac34x[/tex]

Slope:-

[tex]\\ \tt\Rrightarrow m=\dfrac{6+3}{8+4}=\dfrac{9}{12}=\dfrac{3}{4}[/tex]

Equation of line in point slope form

Answer

18,080

Explantion

400x10=4000x4=16000

400x5=2000

2000+16000=18000

400×.2=80

cause 20% of 400 is 80

so total is 18,080

R11 000 in a year.

Step-by-step explanation:

Therefore:

52 weeks - 2 weeks unpaid = 50 weeks

50 weeks × R220 = R11 000 in a year

To simplify, we multiply each single one in the first bracket with both in the second bracket :

[tex](3x+1)(3x-5) = 9x^{2} -15x + 3x - 5[/tex]

Answer:

Step-by-step explanation:

180° ( n - 2 )

n = 6 sides

4( x )° + 2( x - 6 )° = 180° ( 6 - 2 )

4x + 2x - 12 = 720

6x = 732

x = 122

x° = 122 °

( x - 6 )° = 116 °

122° + 116° + 122° + 122° + 116° + 122° = 720°

Replace x in the equation and see which one equals the y values:

The answer is f(x) = 2x - 1

1. Convert the 1 and 2/3 from mixed partial fractions to improper fractions to make it a bit simpler to calculate

⇒ [tex]1\frac{2}{3} = \frac{5}{3}[/tex]

2. Now lets the change the base of both fractions into a common denominator and solve

⇒ [tex]\frac{5}{3}-\frac{1}{4} = \frac{5*4}{3*4} -\frac{1*3}{4*3} =\frac{20}{12}-\frac{3}{12} =\frac{20-3}{12} =\frac{17}{12} = 1\frac{5}{12}[/tex]

Answer: [tex]\frac{17}{12}[/tex] or [tex]1\frac{5}{12}[/tex]

Answer:

v = [tex]\frac{7\sqrt{2} }{2}[/tex]

u = [tex]7[/tex]

Step-by-step explanation:

First, the angle on the far left is also 45 degrees.

So, v is equal to [tex]\frac{7\sqrt{2} }{2}[/tex] because this is a 45-45-90 triangle, so the sides opposite the 45-degree angles are congruent.

However, u is the side opposite the 90-degree angle, so it is equal to the other side value, multiplied by [tex]\sqrt{2}[/tex].

So, [tex]\frac{7\sqrt{2}}{2}*\sqrt{2}[/tex] is equal to:

[tex]7[/tex]
