Angel has $60 and his sister has $120. Angel saves $7 per week, and his sister saves $5 per week. Which equation and solution represent the number of weeks, w, it will take for the siblings to have the same amount of money?

A. 7w + 60 = 5w + 120; w = 30

B. 60w + 7 = 120w + 5; w = 30

C. Not here

D. 7w - 60 = 5w - 120; w = 30

Answer:

23,040 cm^3.

Step-by-step explanation:

The case will be 6 * diameter of a can in length,

= 6* 8= 48 cm.

The width will be 4 * 8 = 32 cm.

The height = height of each can

= 15 cm.

So the volume of the case = 15*32*48

= 23,040 cm^3.

Answer:

Step-by-step explanation:

The quadratic formula would be the following...

[tex]x = \frac{-b (+-)\sqrt{b^{2} - 4ac } }{2a}[/tex]

where the original quadratic equation would be represented as follows

[tex]ax^{2} + bx +c = 0[/tex]

Using this information and the information provided in the image we can plug in the quadratic equation values in the image to form the quadratic formula.

[tex]\frac{-(-20)±\sqrt{(-20)^{2} - 4(16)(-6) } }{2(16)}[/tex]

That would be the correct order for the values.

Answer:

B

Step-by-step explanation:

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

A polygon is a closed figure made up of three or more line segments connected end to end.

A polygon in the plane has rotational symmetry when the figure is mapped onto itself by rotating between 0 and 360° about its center.

So, we need to find the number of symmetrical lines a regular polygon.

A regular polygon with a sides has n lines of symmetry and order of symmetry.

Then, let a be the number of symmetrical line lines

An algebraic expression represents the number of degrees of rotation about the polygon’s center that would carry the polygon onto itself is 360 / a.

Answer:

PQ = 6.8

Step-by-step explanation:

Corresponding sides of similar shapes or figures are proportional to each other. Since ∆LMN ~ ∆OPQ, the ratio of their corresponding sides would therefore be equal. Thus:

LN/OQ = MN/PQ

LN = 5

OQ = 17

MN = 2

PQ = ?

Plug in the values

5/17 = 2/PQ

Cross multiply

5*PQ = 2*17

5*PQ = 34

PQ = 34/5

PQ = 6.8

Answer:

(-1,-2)

Step-by-step explanation:

Answer:

551.8 feet

Step-by-step explanation:

We are given

Adjacent = 1300 feet

Opposite = x

Angle = 23°

We solve using the trigonometric function Tangent

tan θ = Opposite/Adjacent

tan 23 = x/1300 feet

Cross Multiply

x = tan 23 × 1300 feet

x = 551.81726107 feet

Approximately = 551.8 feet

The Length of the building = 551.8 feet

Answer:

 =  1 0

Step-by-step explanation:

Solve

1. Combine like terms

2  +  2 0  + 2  =  6 0

4  +  2 0  =  6 0

2. Subtract  20  from both sides of the equation

4  +  2 0  =  6 0

4  +  2 0  −  2 0  =  6 0  −  2 0

3. Simplify

4  +  2 0  −  2 0 =  6 0  −  2 0

4  =  6 0  −  2 0

4 =  6 0  −  2 0

4  =  4 0

4. Divide both sides of the equation by the same term

4x = 40

4x/4 = 40/4

5. Simplify

4x/4 = 40/4

x = 40/4

x = 40/4

x = 10

Answer:

The mean of the data points is 2.

Step-by-step explanation:

The mean of data is all data point values added together and divided by the number of data points, or the average of all data points. All the numbers above added together is 42, and there are 21 data points, which means the mean of the data is [tex]\frac{42}{21}[/tex] or 2.

Answer:

2

Step-by-step explanation:

Add all the numbers up then divide by how many number there are to find the mean

4 + 2 + 4 +1+ 1+2+2+3+ 0+ 2+ 1+1+4 +2+5+2+1+1+0+ 2+2 =42

42 divided by 21= 2

Answer:

The answer is b

Step-by-step explanation:

X= 0 makes the exponential function greater than the quadratic function. Therefore, the correct option is option B.

The mathematical symbol for the exponent is [tex]e^{X}[/tex]. The word, unless specifically stated differently, generally relates to the positive-valued functional of something like a real variable, though it can be extended towards the complex numbers or adapted to other mathematical like matrices or Lie algebras.

The idea of exponentiation is where the exponential function got its start, although recent definitions allow for a rigorous extension to all real arguments, especially irrational values. X= 0 makes the exponential function greater than the quadratic function.

Therefore, the correct option is option B.
