According to one study, the average monthly cell phone bill in the U.S. is $70. If a 20-year old student with an average bill gives up her cell phone and each month invests the $70 she would have spent on her phone bill in a savings plan that averages a 4% annual return, how much will she have saved by the time she is 65?

Answer:

-8, -1.5, 1/2, 1/4, 1/2, 1, 2.5, 3

Step-by-step explanation:

Answer:

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2 (if is not 11/2 but 1  and 1/2) the answer is : -8, -1.5 , -1/2 , 1/4 , 1/2, 1 , 2.5, 3

Step-by-step explanation:

First of all we have to express the decimal numbers with a fraction

2.5 = 25/10 = 5/2

-1.5 = -15/10 = -3/2

now we have to express al numbers with a fraction with the same denominator. In this case the value that help us the most is 4

-1/2 = -2/4

5/2 = 10/4

-8 = -32/4

1/4 = 1/4

11/2 = 22/4

-3/2 = -6/4

3 = 12/4

now we have to check only the numerators for discover the order of the numbers. So from the least to the greatest we have:

-32/4 ; -6/4 ; -2/4 ; 1/4 ; 10/4 ; 12/4 ; 22/4

the final step is rewrite the original numbers in this order

-8, -1.5 , -1/2 , 1/4 , 2.5, 3 , 11/2

No a polygon only has 3 sides and 3 angles.

FACTORED ANSWER

2(15)x)

Step-by-step explanation:

Answer:

[tex]x = 0[/tex]

Step-by-step explanation:

Factor 6x⋅2 out of 6x⋅2+24x.

[tex]6x \times (2(1 + 2)) = 0[/tex]

Multiply 2 by 6.

[tex]12x(1 + 2) = 0[/tex]

Add 1 and 2.

[tex]12x \times 3 = 0[/tex]

multiply 3 by 12.

[tex]36x = 0[/tex]

Divide each term by 36 and simplify.

[tex]x = 0[/tex]

therefor, the answer is 0.

Answer:

-5<x<9

Step-by-step explanation:

Within a triangle, the greater an angle, the greater the length of opposite side. So, since we know that 42° gives an opposite side of 23, and (3x+15)° gives an opposite side of 21, (3x+15) must be less than 42:

3x+15<42

3x<27

x<9

We also know that the angle (3x+15)° cannot equal zero or less than zero. So find x when 3x+15=0, and note that our value for x must be greater than this:

3x+15=0

3x=-15

x=-5

so, -5<x

Put both parts together to get: -5<x<9

Step-by-step explanation:

Given

Truck A speed is [tex]v_a=60\ kmph[/tex]

Truck B speed is [tex]v_b=80\ kmph[/tex]

Truck A leaves 2 hours before truck B

Distance traveled in the 2 hour

[tex]\Rightarrow 60\times 2=120\ km[/tex]

Suppose Truck B will catch truck A after t hours

[tex]\therefore 120+60t=80t[/tex]

Answer:

The volume is 588 ft³

Step-by-step explanation:

[tex]v = a {}^{2} \frac{h}{3} = 14 {}^{2} \times \frac{9}{3} = 588[/tex]

Answer:

254.6 ft3 F

Step-by-step explanation:

To find the volume of the pyramid, first calculate the area of the base.

As the pyramid is the regular triangular pyramid, the base is an equilateral triangle.

To find the area of the equilateral triangle, calculate the length of the height.

Since the triangle is equilateral, each angle in the triangle equals 60°.

The height forms a 30°- 60°- 90° triangle. One leg of this triangle is equal to half of the side of the large triangle, or 7 ft. The other leg of the triangle is equal to 73‾√ ft by the 30°- 60°- 90° Triangle Theorem.

Therefore, the length of the height of the triangle is 73‾√ ft.

To find the area of the base of the pyramid, B, use the formula for the area of a triangle, B=12bh.

Substitute 14 for b and 73‾√ for h.

B=12⋅14⋅73‾√

Simplify.

B=493‾√ ft2

To find the volume of the pyramid, use the formula for the volume of a pyramid, V=13Bh.

Substitute 493‾√ for B and 9 for h.

V=13⋅493‾√⋅9

Simplify.

V=1473‾√

Use a calculator to approximate.

V≈254.6 ft3

Therefore, the volume of the regular triangular pyramid is about 254.6 ft3.

0.75(0.25x+8)-(0.5x+2)=0.375(4-x)-0.25x

0.1875x+6-0.5x-2=1.5-0.375x-0.25x

0.1875x-0.5x+0.375x+0.25x=1.5-6+2
