Answer:

2nd Option

3rd Option

Step-by-step explanation:

Linear equations are equations with a variable degree of 1.

Choice 1 is a function and a linear equation

Choice 4 is a linear equation but not a function

Quadratic equations are equations with variable degree of 2

(So choice 2 isn't a linear equation)

Cubic equations are equations with variable degree of 3

(So choice 3 isn't a linear equation)

Answer:

Option (1)

Step-by-step explanation:

Let the number of adult tickets sold = x

And the number of child tickets sold = y

Cost of adult tickets sold = $8x

And the cost of child tickets sold = $4y

If the theater company needs to earn at least $1280,

8x + 4y ≥ 1280

2x + y ≥ 320 ---------(1)

Since community center has a capacity of 240 people,

x + y ≤ 240 ----------(2)

By graphing these inequalities with the help of a graphing tool,

Shaded area above the solid line will be represented by inequality (1) (red line)

And the shaded area below the line will be the represented by inequality (2) (blue line)

Common area of both the shaded regions will represent the solution area .

Option (1) will be the answer.

Answer:

1260cm^3is answer.

Step-by-step explanation:

given,

l=10cm

b=7cm

and h=18cm

now, v= area of base ×height

or,v=((7×10)×18)

therefore, volume=1260cm^3.

Answer:

i think t is 1067.66

Step-by-step explanation:

volume of a square pyramid: V=a^2*h/3 since it is square all sides are equal

a=10, the height=18-7=11

V=10^2*11/3= 366.67 cm^3

the volume of the square pyramid= Area *height= length*width*height

V=10*10*7=700 cm^3

volume of the shape is : 366.67+700=1066.66

Check Explanation

Step-by-step explanation:

The number line required to answer this question is missing.

But I'll explain how to get the total number of basketball cards Juan has, given the number that corresponds to 60% of the total number of cards.

Let the total number of basketball cards be x.

The first step is to check the number line presented. We furst require the number that corresponds to 60% of all of Juan's basketball cards..

Let us assume that the number of basketball cards according to the number line is 45.

This means that

60% of the total number of basketball cards = 45

60% × x = 45

0.6x = 45

x = (45/0.6) = 75 basketball cards.

So, the way to go is just to divide the number that the number line gives (which represents 60% of the total number of basketball cards) by 0.6 to obtain the total number of basketball cards.

Step-by-step explanation:

Answer:

To prove that 3·4ⁿ + 51 is divisible by 3 and 9, we have;

3·4ⁿ is divisible by 3 and 51 is divisible by 3

Where we have;

[tex]S_{(n)}[/tex] =  3·4ⁿ + 51

[tex]S_{(n+1)}[/tex] = 3·4ⁿ⁺¹ + 51

[tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] = 3·4ⁿ⁺¹ + 51 - (3·4ⁿ + 51) = 3·4ⁿ⁺¹ - 3·4ⁿ

[tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] = 3( 4ⁿ⁺¹ - 4ⁿ) = 3×4ⁿ×(4 - 1) = 9×4ⁿ

∴ [tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] is divisible by 9

Given that we have for S₀ =  3×4⁰ + 51 = 63 = 9×7

∴ S₀ is divisible by 9

Since  [tex]S_{(n+1)}[/tex] - [tex]S_{(n)}[/tex] is divisible by 9, we have;

[tex]S_{(0+1)}[/tex] - [tex]S_{(0)}[/tex] =  [tex]S_{(1)}[/tex] - [tex]S_{(0)}[/tex] is divisible by 9

Therefore [tex]S_{(1)}[/tex] is divisible by 9 and [tex]S_{(n)}[/tex]  is divisible by 9 for all positive integers n

Answer:

Mass of the things=8.7kg

Mass of the bag=660g=0.66kg

Total mass=mass of the bag+mass of the things

Total mass=8.7kg+0.66kg

Answer:

Maximum Congestion: 24

Maximum Time to reach Congestion: 3

Step-by-step explanation:

Easiest and fastest way is to graph the equation and analyze the graph for it's maximum vertex.

Answer:

t = 3

24 km of congestion.

Step-by-step explanation:

To find the maximum time, we want to know the coordinates of the vertex of the parabola. To get the x-value of the vertex, we would do -b/2a. In this case, a = -1 and b = 6. So, we will have -(6) / 2 * (-1) = -6 / -2 = 6 / 2 = 3.

To get the y-value of the vertex, just substitute the 3 whenever it says "t".

f(3) = -(3)^2 + 6 * (3) + 15 = -9 + 18 + 15 = 9 + 15 = 24

So, the maximum time it takes to reach the value is t = 3, and the maximum number of congestion in the city will be 24 km.

Can I have brainliest???

Answer:

hey I'm going to be able to make it to the meeting

Step-by-step explanation:

hi the address is correct but the number is not

The first column is found by plugging in the x values to get corresponding y values. For instance, if x = -5, then y is...

y = x^2+3x-18

y = (-5)^2+3(-5)-18

y = 25-15-18

y = 10-18

y = -8

So that explains how they got -8 in the second column, next to x = -5.

--------------

The column of first differences is found by subtracting the adjacent terms in the y column. The distance from y = -8 to y = -14 is 6 units, so we'll write 6 in the first row of the "first differences" column. The rest of the values of this column are filled out in a similar fashion. This means that you'll need to completely fill out the y column before you can move onto the "first differences" column.

--------------

The second differences is found by subtracting the adjacent first differences. You should find the results of this column are all the same value. This is true of any quadratic function.

Answer:

The submarine is  307.8 yards below sea level.

Step-by-step explanation:

Since the 500 yards are the hypotenuse of the right angle triangle, the acute angle opposite the side of the triangle we need to find is known ([tex]38^o[/tex]), we can use the sine function to solve the problem:

[tex]sin(\theta)=\frac{opposite}{hypotenuse} \\sin(38^o)=\frac{x}{500} \\500\,*\,sin(38^o)=x\\x = 307.8307\,\,yards[/tex]

which rounded to the nearest tenth is : 307.8 yards

The transformation was a 90° rotation about the origin.

Step-by-step explanation:

Triangle ABC was transformed using the rule (x, y) → (–y, x). The vertices of the triangles are shown. A (–1, 1) B (1, 1) C (1, 4) A' (–1, –1) B' (–1, 1) C' (–4, 1) Which best describes the transformation? The transformation was a 90° rotation about the origin. The transformation was a 180° rotation about the origin. The transformation was a 270° rotation about the origin. The transformation was a 360° rotation about the origin.

Answer: Transformation is the process of moving a point in a graph to another point. The new point formed is the image of the old point. When an object is transformed each point of the object is moved to another point. There are three types of transformation: Reflection, Rotation, Translation and dilation.

If a point O(x, y) is rotated 90° rotation about the origin., the new point is at O'(-y, x). That is the x coordinates becomes negative of the y coordinate and the y coordinate becomes the x coordinate.

The vertices of the triangles are shown. A (–1, 1) B (1, 1) C (1, 4), If a transformation of 90° rotation about the origin is done, the new points are A' (–1, –1) B' (–1, 1) C' (–4, 1)

Answer:

587.18 square inches

Step-by-step explanation:

We would find the Total surface area of the cone

Diameter of the cone = 11 inches

Radius = Diameter ÷ 2 = 11 / 2 = 5.5 inches

Slant height ( l ) = 28.5 inches

Let's take π = 3.14

Total Surface Area of a cone = πrl + πr²

= πr(l + r)

= 3.14 × 5.5( 28.5 + 5.5)

= π × 5.5(34)

= 587.18 square inches

Answer:

m = [tex]\frac{29}{18}[/tex]

Step-by-step explanation:

=> (-11/6) + m = -2/9

Adding 11/6 to both sides

=> m = [tex]-\frac{2}{9} + \frac{11}{6}[/tex]

LCM = 18

=> m = [tex]\frac{-4+33}{18}[/tex]

=> m = [tex]\frac{29}{18}[/tex]

Answer:

m = 29/18

Step-by-step explanation:

(-11/6) + m = -2/9

Add 11/6 on both sides.

m = -2/9 + 11/6

Make denominators equal and add.

m = -12/54 + 99/54

m = 87/54

m = 29/18

1)0.123( bar on 3)

Let X = 0.123 ( bar on 3)

Then X = 0.1233 --------(1)

Multiply equation (1) by 100 we get,

100X = 12.33 --------(2)

Again multiply equation (2) by 10 we get,

1000X = 123.33 -------(3)

Subtract equation (2) from equation (3) we get,

1000X = 123.33

100X = 12.33

900X = 111

X = 111/900

Hence,

0.123 ( bar on 3) is in the form of 111/900 which is in the form of P/Q.

Explanation:

From the question, we are told that a pet shop sells guinea pigs and goldfish and that the ratio of guinea pigs to goldfish is 20:28.

a) Give this ratio in its simplest form.

The ratio of guinea pigs to goldfish is 20:28. The highest common factor to 20 and 28 is 4. Therefore 20 = 4 × 5 and 28 = 4 × 7. So, the ratio in its simplest form will be 5:7.

b. The shop has a total of 120 guinea pigs and fish. Work out the number of guinea pigs the shop has.

The ratio of guinea pig and goldfish is 5:7. If the shop has a total of 120 guinea pigs and fish, the number of guinea pigs the shop has will be:

= 5/12 × 120

= 5 × 10

= 50 guinea pigs
