Answer:

t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6  ( using the same denominator)

t = 13/6 = 2 1/6

We can also distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get a common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6

ANSWER : t = 2 1/6

1/5 t + 2/5 = 5/6

Step-by-step explanation:

1/5 (t + 2) = 5/6

Multiply each side by 5

t+2 = 5*5/6

t+2 = 25/6

Subtract 2 from each side

t+2 -2 = 25/6 -12/6

t = 13/6 = 2 1/6

We can distribute

1/5 t + 2/5 = 5/6

Subtract 2/5 from each side

1/5t = 5/6 -2/5

Get common denominator

1/5t =25/30 - 12/30

1/5t = 13/30

Multiply each side by 5

t = 13/30 *5

t = 13/6

Answer:

In 2008 the US population was 4.55% of the world population.

Step-by-step explanation:

In order to calculate the percent of the world population that represents the US population, we can apply a rule of three in such a way that the world population is related to 100% in the same proportion that the US population is related to x%. We then solve for x. This is shown below:

6.7*10^9 -> 100%

305*10^6 -> x%

6.7*10^9 / 305*10 ^6 = 100 / x

6.7*10^3 / 305 = 100 / x

(6.7*10^3)*x = 305*100

x = 30500 / (6.7*10^3)

x = 4,55 %

In 2008 the US population was 4.55% of the world population.

Answer:

[tex](x-8)^2 + (y-7)^2 - 17 = 0[/tex]

Step-by-step explanation:

The formula for the equation of a circle is:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where (h,k) is the center and r is the radius of the circle.

To first solve solve this, use the endpoints of the diameter to solve for the center of the circle using the midpoint formula, which is known as:

[tex]\frac{(x_1+x_2)}{2},\frac{(y_1+y_2)\ }{2}[/tex]

The points given are (12,8) and (4,6), so plug in the coordinates into the formula.

Center = (1/2)(12+4),(1/2)(8+6)

            = (8,7)

Now, to find the radius, we can use the distance formula and use the center (8,7) and one of the endpoints, (12,8). The distance formula is known as:

[tex]\sqrt{(x_{1} -x_{2})^2 +(y_{1} -y_{2})^2 }[/tex]

Radius = √(x₂- x₁)² + (y₂-y₁)²

            = √(12- 8)² + (8-7)²

            = √(4² + 1²) = √(16+ 1) = √17

            = r² = 17

Now that the radius and the center are known, the equation of the circle can be written as:

[tex](x-8)^2 + (y-7)^2 - 17 = 0[/tex]

Answer: (71,19)

Step-by-step explanation:

x + y =90

x=14 + 3y    or -1x +3y=-14

solve by elimination.  1x + 1y= 90

                                    -1 +3y = -14   y=19

1x + 1(19)=90  

x=71

Answer:

x + y = 90

x = 14 + 3y

The numbers are 71 and 19.

Step-by-step explanation:

Let the larger number be x.

Let the smaller number be y.

The sum of the numbers is 90.

x + y = 90

The larger number, x, is 14 more than 3 times the smaller number, y.

x = 14 + 3y

We have a system of two equations in two unknowns.

x + y = 90

x = 14 + 3y

Since the second equation is already solved for x, we will use the substitution method to solve the system of equations.

Substitute x in the first equation with 14 + 3y.

x + y = 90; x = 14 + 3y

14 + 3y + y = 90

Combine like terms on the left side.

4y + 14 = 90

Subtract 14 from both sides.

4y = 76

Divide both sides by 4.

y = 19

The smaller number is 19.

Now we substitute 19 for y in the first equation and solve for x.

x + y = 90; y = 19

x + 19 = 90

Subtract 19 from both sides.

x = 71

The larger number is 71.

Answer: The numbers are 71 and 19.

Answer:

The correct options are;

1) Sandy is correct

2) The figure was divided into two rectangular prisms that are calculated separately

Step-by-step explanation:

Here we have to divide the figure into two rectangular prisms so as not to calculate for a dimension twice

Therefore, the figure can be split into a horizontal prism at the top with dimensions and volume = 10 × 4 × 3 and the vertical prism below will now have a dimension and hence, volume of 4 × 4 × 3

Therefore the volume of the figure is the sum of the volumes of the two prisms found as follows;

Volume of the figure =  10 × 4 × 3 + 4 × 4 × 3  = 168

We can try the othe way to confirm as follows

Volume of the prism below = 4 × 3 × 8 = 96

Volume of the horizontal prism above is now = 4 × 3 × 6 = 72

Volumre of the figure = 96 + 72 = 168

Therefore, since the volume = (10 × 4 × 3) + (4 × 4 × 3), Sandy is correct

Because the figure was divided into two rectangular prisms that are calculated separately.

Answer:

20.03

Step-by-step explanation:

To find the perimeter of the triangle, we need to find the length of each side, and we can do this finding the distance from each pair of vertix of the triangle:

Knowing that P = (3, -4), A = (-4, 1) and Z = (-2, 3), we have:

side PZ: distance = sqrt((3 - (-2))^2 + (-4 - 3)^2) = 8.6023

side PA: distance = sqrt((3 - (-4))^2 + (-4 - 1)^2)  = 8.6023

side AZ: distance = sqrt((-4 - (-2))^2 + (1 - 3)^2) = 2.8284

So the perimeter is PZ + PA + AZ = 8.6023 + 8.6023 + 2.8284 = 20.03

Step-by-step explanation:

In the system of equations, x represents the,  price to wash a car and y represents the price to wash an SUV.

If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.

x=12 and y = 18

x+y = 12+18 = 30

The total cost of 1 car and 1 SUV is $_30____.

5x+4y = 5(12)+4(18) = 60+ 72 =132

The total earnings for hour 3 are $_132_____.

Answer:

x: cost of 1 car wash

y: cost of each SUV wash

(12,18)

The total cost of 1 car and 1 SUV is $30

The total earnings for hour 3 are $132

Step-by-step explanation:

4x + 2y = 84

y = 42 - 2x

3x + 5y = 126

3x + 210 - 10x = 126

7x = 84

x = 12

y = 42 - 2(12) = 18

1 car and 1 SUV

12 + 18 = 30

For 3 hours:

I’m not super good at explain but, the height and incline both go at the right slope when they interact. Have a good day, hope it helps.

The length of the pyramid's base would be:

C). 235 meters

Given that,

Height of the pyramid [tex]= 221[/tex]

Elevation/angle of the base [tex]= 62[/tex]°

Employing the trigonometric function,

Tan 62 [tex]= 221/[1/2 base][/tex]

⇒ Base [tex]= (2[/tex] × [tex]221)[/tex][tex]/Tan[/tex][tex]62[/tex]

[tex]= 2[/tex] × 221/[tex]1.88[/tex]

[tex]= 235.10[/tex]

Answer:

2x + y = -5 (which is Answer 1).

Step-by-step explanation:

The possible answer choices are all versions of the standard equation of a straight line:   Ax + By + C = 0.  If A and B are both positive, as they are here, then the slope is negative and has the form m = -A/B.  Only the first answer choice passes here:  with +2x and +1y, the slope is -2.  This automatically eliminates the other possibilities.

Looking at the first answer choice, we see that A must be 2 and B must be 1

so that the slope is m = -2.    Writing out this equation:  Ax + By + C = 0.

Replace A with 2 and B with 1:  2x + y + C = 0.

Finally, replace x with -1 and y with -3:  2(-1) + (-3) + C = 0.

Solving this for C, we get   -2 - 3 + C = 0, or -5 + C = 0, or C = 5.

We end up with 2x + y = -5 (which is Answer 1).
