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

I hope this help you my friend, have a good day

Answer:lim x- √16-x²=32

Step-by-step explanation:

[tex]x^{4}[/tex]-16

=(x²)²-4²

=(x²-4)(x²+4)

=(x²-2²)(x²+4)

=(x-2)(x+2)(x²+4)

So:

[tex]\frac{x^{4}-16 }{x-2}[/tex]=[tex]\frac{(x-2)(x+2)(x^{2}+4) }{(x-2)}[/tex]=(x+2)([tex]x^{2}[/tex]+4)

with exclusion:

x[tex]\neq[/tex]2

Hence:

lim [tex]\frac{x^{4}-16 }{x-2}[/tex]

Alternate Interior Angles are formed on the interior of the parallel lines, on the opposite sides of the transverse. The value of x is 14.

When two parallel lines are cut by a transverse. the angles formed on the interior of the parallel lines, on the opposite sides of the transverse are known as the Alternate Interior Angle.

As we can see in the centre where the triangle is formed, the measure of the different angles can be written as,

Vertically opposite Angles, [tex]\angle A = 53^o[/tex]

Alternate Interior Angles, [tex]\angle C = 57^o[/tex]

[tex]\angle B = 5x[/tex]

Now, the sum of all the angles of this triangle can be written as,

[tex]\angle A+\angle B+\angle C = 180^o\\\\53^o + 5x + 57^o = 180^o\\\\110^o + 5x = 180^o\\\\5x = 180^o-110^o\\\\5x = 70^o\\\\x = 14[/tex]

hence, the value of x is 14.

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

Answer:

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:

100

Step-by-step explanation:

The fraction 2/3 says there are 3 total parts to the track, but Pete only rode 2 of them.

In this type of problem you always multiply the amount of the whole (150) times the fraction of the whole you are calculating (2/3) to get the answer.

150*2 = 300 divided by 3 = 100

Or 150 * (2/3) = 150 * 0.66667 = 100

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

[tex]\\ \tt\Rrightarrow y+3=3/4(x+4)[/tex]

[tex]\\ \tt\Rrightarrow y+3=3/4x+3[/tex]

[tex]\\ \tt\Rrightarrow y=3/4x[/tex]

equation of shaded region

[tex]\\ \tt\Rrightarrow y\leqslant 3/4x[/tex]

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

Step-by-step explanation:

I believe you meant 8x−y^2−3.    The expression 8x−y2−3 is meaningless.

Letting x take on the vaue -1/4 and y the value 3, we get:

8(-1/4) − (3)^2−3, or

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]

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°
