. For what value of x do the expressions 2x +2 and 3x – 6 have the same value?

Answers

Answer:

x = 8

Step-by-step explanation:

To find the solution, equate the 2 expressions, that is

3x - 6 = 2x + 2 ( subtract 2x from both sides )

x - 6 = 2 ( add 6 to both sides )

x = 8

As a check

2x + 2 = 2(8) + 2 = 16 + 2 = 18

3x - 6 = 3(8) - 6 = 24 - 6 = 18

Both expressions have the same value when x = 8

The equation h = -16t 2+ 53x + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked. What is the maximum height the football reaches?

Answers

Answer: The maximum height the football reaches = 51.89 feet.

Step-by-step explanation:

Given: The equation [tex]h = -16t^2+ 53t + 8[/tex] gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.

Differentiate the given equation, we get

[tex]h'=-(2)16t+53=-32t+53[/tex]   (i)

Put [tex]h'=0[/tex]

[tex]\Rightarrow\ -32t+53=0\\\\\Rightarrow\ t=\dfrac{53}{32}\approx1.65625[/tex]

Differentiate (i) w.r.t. t, we get

[tex]h''=-32[/tex] < 0  i.e. h is maximum at t= 1.65625

The value of h at t= 1.65625 will be [tex]-16(1.65625)^2+53(1.65625)+8=51.890625\approx51.89\text{ feet}[/tex]

Hence, the maximum height the football reaches = 51.89 feet.

If 3 x/4 +2 =56.8, what is the value of x?

A) x≈ −2.891
B) x≈ 6.708
C) x≈ −4.323
D) x≈ −2.059

Answers

Answer:

the value of the x is 73.07

Step-by-step explanation:

The computation of the value of the x is shown below:

Given that

3x ÷ 4 + 2 = 56.8

3x + 8 ÷ 4 = 56.8

3x + 8 = 56.8 × 4

3x + 8 = 227.2

3x = 227.2 - 8

3x = 219.2

x = 73.07

Hence, the value of the x is 73.07

Melody Pond and a tree cast a shadow at the same time of day. Melody is 5.6 feet tall and casts a 10-foot shadow. If the length of the tree's shadow is 62 feet, what is the height of the tree?

Answers

Answer:

34.72 feets

Step-by-step explanation:

Using the relation :

Length of tree / shadow of tree = height of melody / shadow of melody

From the details given in the question :

Let height of tree = h

h / 62 = 5.6 / 10

Cross multiply

h * 10 = 62 * 5.6

h = 347.2 / 10

h = 34.72 feets

Hence, the height of tree is 34.72 feets

How many different 4-digit PIN codes are there that only include the digits 4, 5, 6, 7, 8 and 9
if each of those digits is only allowed to be used once?

Answers

Answer:

ecall that 6 + 6 + 6 = 6 × 3

Instead of adding 6 three times, you can multiply 6 by 3 and get 18, the same answer.

Similarly,

6 + 6 + 6 + 6 + 6 + 6 + 6 = 6 × 7 = 42

Still by the same token,

2 + 2 + 2 + 2 = 2 × 4

In algebra, 2 × 4 can be written as (2)(4)

You can think of this as four groups of 2.

Answer:

21

Step-by-step explanation:

-10+59 = 5m = 7 + 3m

A beachball has a radius of 10 inches. Find the volume of the beachball, in cubic inches.
Round your answer to the nearest whole number.

Answers

Answer:

4189 cubic inches

Step-by-step explanation:

Use the formula for the volume of a sphere: V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

Plug in the radius as r, and simplify:

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](10³)

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex](1000)

V = 4188.79

Round to the nearest whole number

= 4189

So, the volume of the beachball is 4189 cubic inches

Heather Johnson bought a new set of tires for $436.00 and a car seat for $22.85. The state tax rate is 6%, the county tax rate is 1.5%, and the city tax rate is 0.5%. What is the total purchase price?

Answers

Answer:

$495.56

Step-by-step explanation:

Tax increases the price paid for a good or service. So, the total price paid for the goods would increase by the total amount of tax

Sum of the three taxes = 6% + 1.5% + 0.5% = 8%

Total cost of items purchased = $436 + $22.85 = $485.85

Total purchase price = Total cost of items purchased x (1 + total tax)

$485.85 x (1.08) = $495.56
