The number of hours does each group member work on the project is 4 hours. Therefore, the correct answer is option B.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is x+45/4=4x.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

4x-x=45/4

3x=45/4

x=15/4

x=3.75

x≈4 hours

Therefore, option B is the correct answer.

Answer:

yes it is

Step-by-step explanation:

1) Note that in the problem above, the complete table is given as:

Team Number:     1             2      3           4           5

Best Jump (ft)       20.6    21.5    20.9      19.4        20.2

2) If Best Jump is denoted as y and Team number as x then, Best Jump is the Range while Team Number is the Domain.

3) For each element of the domain, there is a corresponding element of the range. So this relation is a function.

Domain and range are crucial characteristics that aid in the definition of a relationship. The domain is a collection of input values.

The independent variable represents these values, which are graphed on the axis of a coordinate graph. A function's range is its collection of output values.

Answer:

160 in³

Step-by-step explanation:

Volume of rectangular pyramid, V = (Length * width * height) / 3

Length = 10 in ; width = 8 in ; height = 6 in

V = (10 * 8 * 6) / 3

V = 160 in³

Answer:

62ft²

Step-by-step explanation:

Hi there!

Surface area is calculated by this formula:

2(length*width)+2(width*height)+2(length*height)

*note: we multiply each area by 2, as the prisim has 6 faces, or 2 of each face

we're given a length of 5 ft, a width of 2 ft, and a height of 3ft

now let's calculate the surface area

to find the area of the first two faces:

2(length*width)

2(5*2)

2(10)

20 ft²

now to find the area of the second two faces:

2(width*height)

2(2*3)

2(6)

12 ft²

finally, find the area of the last two faces:

2(length*height)

2(3*5)

2(15)

30 ft²

now add up all the values

SA=20+12+30=62 ft²

your answer is 62ft²

Hope this helps!

Answer: Statement 2 (P(odd number) = 1/2) is true

Step-by-step explanation:

Statement 1: there are 4 even numbers (2, 4, 6, 8) so therefore a 1/2 chance, not a 1/8. [FALSE]

Statement 2: there are 4 odd numbers (1, 3, 5, 7) so therefore a 1/2 chance, so this is true. [TRUE]

Statement 3: 8 is the biggest number, so there are 7, not 1, numbers less than it. [FALSE]

Statement 4: there is no 9 on an 8 sided cube. [FALSE]

Answer:

2019

Step-by-step explanation:

2010: 450,000

2011: (5% of 450,000) + 450,000 = 472,500

2012: (5% of 472,500) + 472,500 = 496,125

2013: (5% of 496,125) + 496,125 = 520,931.25

2014: (5% of 520,931.25) + 520,931.25 = 546,977.8125

2015: (5% of 546,977.8125) + 546,977.8125 = 574,326.703125

2015: (5% of 574,326.703125) + 574,326.703125 = 603,043.038281

2016: (5% of 603,043.038281) + 603,043.038281 = 633,195.190195

2017: (5% of 633,195.190195) + 633,195.190195 = 664,854.949705

2018: (5% of 664,854.949705) + 664,854.949705 = 698,097.69719

2019: (5% of 698,097.69719) + 698,097.69719 = 733,002.582049

Answer:

110 in.²

Step-by-step explanation:

The figure is composed of a parallelogram and a rectangle

Therefore, the area of the figure = area of rectangle + area of parallelogram

= Length*Width + base*height

Length = 10 in.

Width = 6 in.

base = 10 in.

height = 5 in.

Area of the figure = 10*6 + 10*5

= 60 + 50

= 110 in.²

Answer:

40.5 m²

Step-by-step explanation:

Area of the shaded = area of the square - area of the triangle

Area of square = s²

s = 9 m

Area of square = 9² = 81 m²

Area of triangle = ½*b*h

b = 9 m

h = 9 m

Area of triangle = ½*9*9 = 40.5 m²

Area of the shaded = 81 - 40.5 = 40.5 m²

Answer: $142

Step-by-step explanation: assume 20miles per gallon.

Then 0.05 gallon per mile.

35psi gives 30/35= 0.85 times the surface on the ground, gives square 0.85^2= 0.73 times more deflection so heatproduction a cycle or at same speed. This gives more fuelconsumption.

I once determined that when driving 50mph/80kmph constant, tires use 25% of the total fuel-consumption.

Higher speed same fuelconsumption by the tires, but more bij the higher speed. But to keep it simple only 50mph.

The fuelconsumption at 30 psi 0.05 gpm, 25% by the rolling resistance is 0.0125mpg. 35psi ,0.73 x0.0125=0.0091gpm.

The windforce stays the same 75% of total is 0.0375mpg+ 0.0091= 0.0466mpg,0.0466gpm/0.05= 93% used of fuel with 35psi then at 30 psi.

So 21000mpj x 0.05gpm= 1050 gallon

21000mpjx 0.466gpm= 979gallon.

Saving 1050-979= 71 gallonx $2= $142

Rounded here and there, and other speeds give other divisions, but to show the idea how to calculate it.

Also if 25% used is right is discussable.

a = 327 m²

Step-by-step explanation:

Area of bed

r = 22/2 = 11

a = 3.14(11²)

a = 379.94

Area of bed and sidewalk

r = 11 + 4 = 15

a = 3.14(15²)

a = 706.5

Area of sidewalk

a = 706.5 - 379.94
