Pls HELP I don’t understand:(

Answer:

Slant height = 8 feet.

Step-by-step explanation:

If the perimeter of the square base = 12 then each side of the base = 12/4

= 3  feet and its area = 3*3 = 9 ft^2

The area of one of the triangular sides = 1/2 * 3 * h where h is slant height.

So total surface area = 57 = 9 + 4 * 1.5h

9 + 6h = 57

6h = 48

h = 8 feet.

Answer:

[tex]x + 4[/tex]

Step-by-step explanation:

The question have missing details.

Because, the question says she collected some cans "after picnic"; This means that she has some cans "before picnic"

So, we assume that she has x bags of can before the picnic.

[tex]After\ Picnic = 4[/tex]

So, the total number of bags collected is:

[tex]Total = Before + After\ Picnic[/tex]

[tex]Total = x + 4[/tex]

If x is 5, then she took 9 bags of can to the recycling center

If x is 2, then she took 6 bags of can to the recycling center

If x is 0, then she took 4 bags of can to the recycling center

Answer:

False.

Step-by-step explanation:

Since The angle sum property of traingke is 180°.

Answer:

No, these lengths will not form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem states that the sum of two sides must always be greater than the third side.

55 + 76 = 131

131 is not greater than 112.

Therefore, these lengths will not form a triangle.

Answer:

-0.7073ft/sec

Step-by-step explanation:

Given the following

Distance covered by Ben = -29feet

Time taken = 41secs

Required

average change in depth each second(speed)

average change in depth each second = Distance/Time

average change in depth each second = -29/41

average change in depth each second = -0.7073ft/sec

Answer:

The answer is -29 divided by 41

Answer:

y = x² + 1

Step-by-step explanation:

y = x² + 1

When x = -3

y = -3² + 1

y = 9 + 1 = 10

When x = -1

y = x² + 1

y = -1² + 1

y = 1 + 1 = 2

When x = 0

y = x² + 1

y = 0² + 1 = 1

When x = 2

y = x² + 1

y = 2² + 1

y = 4 + 1 = 5

All of the x and y values have been correct

Answer:

A

Step-by-step explanation:

the others will not produce the correct value for the image ((y)), if you replace the incognito x in the equation by the -3, you can see that you only obtain the result 10 for y in the first equation. you don't even need to test all the cases.

Answer:

The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same

The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line

Step-by-step explanation:

The given linear equations are;

3·x - 6·y = 9...(1)

x - 2·y = 3...(2)

The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs

Making 'y' the subject of both equations gives;

For equation (1);

3·x - 6·y = 9

3·x - 9 = 6·y

y = x/2 - 3/2

For equation (2);

x - 2·y = 3

x - 3 = 2·y

y = x/2 - 3/2

We observe that the two equations are the same and will have an infinite number of solutions

Answer:

B. x = -4

E. x = 10

Step-by-step explanation:

[tex](x-3)^2=49 \\ \\ x - 3 = \pm \sqrt{49} \\ \\ x - 3 = \pm 7 \\ \\ x = 3 \pm 7 \\ \\ x = 3 + 7, \: \: x = 3 - 7, \\ \\ x = 10, \: \: x = - 4[/tex]

Answer:17

Step-by-step explanation: Multiply Steve’s hourly wage ($7.40) by the hours he worked in a week (16 Hours) that would give you your weekly earnings which would be (7.40x16=$118.40) Then subtract what he saved in the bank from your total (118.40-105=$13.40) then you would divide $13.40 (his leftover money) by $0.75 to find the total number of carnival rides he could ride (13.40/0.75=17.86 rides and because he cannot ride 17 and 86 hundredths of a ride he would be able to ride 17 carnival rides.

Answer:

Las longitudes que se forman entre los vértices y el centro de un polígono regular son;

Los radios del círculo circunscrito

Step-by-step explanation:

Cada círculo de radio, 'r', tiene un polígono que se puede inscribir polígono regular que tiene 'n' lados, donde n ≥ 3 y viceversa, todos los polígonos regulares se pueden inscribir (dibujar) en un círculo, que luego se conoce como la circunferencia del polígono

Dado que un polígono regular se puede inscribir en un círculo, de modo que sus vértices descansen sobre la circunferencia del círculo, entonces el centro del polígono es el centro del círculo que lo circunscribe.

Por lo tanto, las longitudes (iguales) que se forman entre los vértices y el centro del polígono regular son el radio del círculo que lo circunscribe..

Answer:

see explanation

Step-by-step explanation:

The exponents can only be added if the bases are the same

Here one base is 12 and the other is 11

So the rule of addition is not applicable.

Answer:

Because the bases (12 and 11) are different.

Step-by-step explanation:

You can only add exponents when the bases are the same.

Answer:

AC = 2

BC = [tex]2\sqrt{2}[/tex]

CD = 4

CF = 4

BD = [tex]2\sqrt{2}[/tex]

DE = 8

EF = [tex]4\sqrt{2}[/tex]

DF = [tex]4\sqrt{2}[/tex]

Step-by-step explanation:

Since all of these are isosceles triangles, it means both legs of every triangle are congruent to each other. So,

Given: AB = 2

Find:

AC = AB = 2

BC = [tex]2\sqrt{2}[/tex]

CD = 4

CF = CD = 4

BD = BC = [tex]2\sqrt{2}[/tex]

DE = 8

EF = [tex]4\sqrt{2}[/tex]

DF = EF = [tex]4\sqrt{2}[/tex]
