Answer:

t= -9

Step-by-step explanation:

Add 76 to both sides

6(t-2)= -142+76

Simplify -142+76 to -66

6(t-2)=-66

Divide both sides by 6

t-2= -66/6

Simplify 66/6 to 11

t-2= -11

Add 2 to both sides

t= -11+2

Simplify -11+2 to -9

t= -9

I hope this helps you

The length of a rectangle is 10 inches longer than its width. If the area of the rectangle is 144 square inches, what are its di
vazorg [7]

Answer:

L= 18 in

W= 8 in

Step-by-step explanation:

Step one:

The length of a rectangle is 10 inches longer than its width

let the width be x

so the lenght is x+10

the area of the rectangle is 144 square inches

Step two:

Area= L*W\\\\144=x(x+10)\\\\144=x^2+10x\\\\x^2+10x-144=0

the factors for the quadratic expression is

18 and -8

x^2+18x-8x-144=0\\\\x(x+18)-8(x+18)=0\\\\x-8=0\\\\x=8\\\\x+18=0\\\\x=-18

the width is 8 in

the length is 8+10= 18 in

Pedro wants to walk from the historic village to the science center the he will walk from the science center to the museum.if he
Zepler [3.9K]

I'm assuming each grid square= 1 square mile.

To do this, you first need to find the total distance.
The first component of his walk takes him from an x-coordinate of 2 to a coordinate of -4 1/2. Since the y-value remains the same, you're not worried about that for this part of the problem. The difference between 2 and -4 1/2 is 6 1/2, so that is your horizontal distance.

Now he walks from the (-4 1/2, -1 3/4) to (-4 1/2, 5 1/4). This time, the x-value is constant, so you only need to worry about the y. As they are on opposite sides of the x-axis, you can add the y-values to get a result of 7, which is your vertical distance.

I just realized I did those distances in reverse order, but it should be ok because the total distance is the same.
To find the total distance, add vertical to horizontal.
6 1/2 + 7 = 13 1/2. This is your total distance.

Now that you have both his speed (given), and total distance, you can find the time it will take him. If he is moving at 4 1/2 mph and the distance is 13 1/2 miles, you can use s=d/t to find the time. 3 1/2 miles divided by the time = 4 1/2 mph. To solve for t, multiply both sides by t and divide that by s, so t= d/s. we know d= 13 1/2 and s= 4 1/2, so t= 13.5 divided by 4.5 = 3. As his speed is in mph, the unit is in hours. Therefore, the answer should be 3 hours.

The base of a solid is bounded by x^2 + y^2 = 16. Cross sections perpendicular to the x-axis are right isosceles triangles with
SVETLANKA909090 [29]

The equation for the base is that of a circle, so the cross sections will have a leg of length equal to the vertical distance between its halves.

x² + y² = 16   ⇒   y = ±√(16 - x²)

⇒   length = √(16 - x²) - (-√(16 - x²)) = 2 √(16 - x²)

Cross sections with thickness ∆x have a volume of

1/2 length² ∆x = 1/2 (2 √(16 - x²))² ∆x = (32 - 2x²) ∆x

since they are isosceles triangles and so their bases and heights are equal.

Then the total volume would be (D)

\displaystyle \int_{-4}^4 \frac12 \left(2 \sqrt{16-x^2}\right)^2 \, dx

Answer:

2 hrs and 21 mins I think

Step-by-step explanation:

I subtracted 328-147 and got 181 and since their is 60 mins in one hr I made it another hour and after I subtracted 81-60 and got 21 minutes. 2 hrs and 21 mins. Hope this makes sense.
