A student adds 10 grams of four different powdered solids into four different beakers. The student then adds 100 mL of water to each beaker, stirs the mixtures, and allows them to sit for half an hour before recording observations. Which question is the student most likely trying to answer with this investigation?

Answer:

(- 7, - 1 )

Step-by-step explanation:

Under a counterclockwise rotation about the origin of 90°

a point (x, y ) → (- y, x ) , thus

(- 1, 7 ) → (- 7, - 1 )

Answer:

-1 >x

Step-by-step explanation:

-4(7+6x)<-2(x-6)

-28-24x<2(x-6)

-28-24x<-2x-6

+6. +6

-22-24x<-2x

+24x +24x

-22 < 22x.

-22÷-22=1 that canceled out

+22÷-22= -1

-1>x. because we divided by a negative the inequality switched.

Answer:

g(x)= x^2-5

g(0)= (0)^2-5

= 0-5

= -5

g(2)= (2)^2-5

=  4-5

= -1

g(4)= (4)^2-5

= 16-5

=11

The answer is C Trina is not correct because the two sides of the equation are equivalent

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

Answer:

Step-by-step explanation:

Formula

V = (4/3) pi r^3

Givens

pi = 3.14

r = 25.9 inches

Solution

V = (4/3) pi r^3                     Substitute values

V = (4/3) * 3.14 * 25.9^3

V = (4/3) * 3.14 *17373.98

V = 72739.1

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.

The amount of Canadian dollar that can be exchanged with NC. 45000 is; 533.69 canadian dollar

We are told that;

NC. 200 = 2.45 Australian dollar

8116 Australian dollar = 8152 canadian dollar

Thus;

NC per Australian dollar = 200/2.45 NC/AUS Dollar

Thus;

200/2.45 NC = 1 Australian dollar

8116/8152 Australian dollar = 1 canadian dollar

Since 1 Australian dollar = 200/2.45 NC , then

8116/8152 Australian dollar = 8116/8152 * 200/2.45

⇒ 81.272 NC

Thus;

81.272 NC = 1 canadian dollar

Then; NC.45000 = 45000/81.272  = 533.69 Canadian dollar

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:

11 2/3

Step-by-step explanation:

Let’s do this

5*2 1/3

Convert the mixed fraction to an improper fraction

2 1/3= 3*2+1=7/3

Now let’s multiply straight across

5*7/3=5/1 * 7/3=35/3

To get mixed number, divide

35/3=11 2/3

And if we convert 11 2/3 to improper, we get 35/3, which is correct. So therefore the answer is 11 2/3.

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°

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
