Answer:

Yes, it depends on how much time he needs. 1.5/4 to run to the lake. 1.5/4 to run back. Not stopping, no cheating. haha

The height of a trapezoid is 8 in. And its area is 96 in2. One base of the trapezoid is 6 inches longer than the other base. Wha

Vsevolod [243]

Answer:

The lengths of the bases are 9 inches and 15 inches.

Step-by-step explanation:

The area of trapezoid is

$=\frac12(\textrm{ sum of parallel sides})\times height$

Given that the height of a trapezoid is 8 in. and its area is 96 in².

Assume the bases of the trapezoid be b₁ and b₂.

Since one base of the trapezoid 6 in. longer than the other.

Let, b₁=b₂+6

The area of the trapezoid is

$=\frac 12 (b_1+b_2)\times8$ in²

$=\frac12 (b_2+6+b_2)\times 8$ in²

$=\frac12(2b_2+6)\times8$ in²

According to the problem,

$\frac12(2b_2+6)\times8 =96$

$\Rightarrow 2b_2+6=\frac{96\times 2}{8}$ [ Multiplying $\frac28$ ]

$\Rightarrow 2b_2+6=24$

$\Rightarrow 2b_2=24-6$

$\Rightarrow 2b_2=18$

$\Rightarrow b_2=\frac{18}{2}$

$\Rightarrow b_2=9$

Then, $b_1=b_2+6$

=9+6

=15 in

The lengths of the bases are 9 inches and 15 inches.

If possible, could someone assist me by showing me how to get the plausible answer as I was absent while my professer went over

Ainat [17]

Answer:

$7.5m^2$

Step-by-step explanation:

Divide the composite shape into two shapes, a rectangle and a triangle.

We can see that the rectangle has dimensions of 3 x 2.

We can use the area formula.

$A=b*h$

$A=3*2$

$A=6$

We can also see that the triangle has a height of 3 and a base of 1 (3 - 2).

We can use the area formula.

$A=\frac{1}{2}(b*h)$

$A=\frac{1}{2}(3)$

$A=1.5$

Now we can add these areas together.

$1.5 +6=7.5$

PLS HELP (AGAIN) ILL MARK BRAINLIEST. I HAVE TO TURN THIS IS ASAP

valina [46]

Step-by-step explanation:

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.

In this case:

1) Diameter = 18 km (given)

Radius = 18/2 = 9 km

2) Diameter = 1 x 2 = 2 m

Radius = 1 m (given)

3) Diameter = 17 x 2 = 34 cm

Radius = 17 cm (given)

4) Diameter = 50 mm (given)

Radius = 50/2 = 25 mm

John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

3 x 2 = 6 meters

6 meters is the diameter.

What is the first step to solve the equation the equation 19 - 7h = 63?

dusya [7]

Answer:

Subtract 63 from both sides

Step-by-step explanation:

we always have to try to clear the incognita that in this case is going to be h

First we

Subtract 63 from both sides

then

Divide by -7 on both sides

19 - 7h = 63

19 - 7h - 19 = 63 - 19

- 7h = 44

-7h/-7 = 44/-7

h = -44/7

Points E, F, and D are on circle C, and angle G

Crank

Answer:

The correct statements are:

1: mEFD = mEGD

3: mED = mFD

5: mFD = 120°

Step-by-step explanation:

Let's analyse each statement:

1: mEFD = mEGD

Let's find the value of the angle ECD, using the sum of the internal angles of a quadrilateral:

$60 + 90 + 90 + mECD = 360$

$mECD = 120\°$

The angle ECD is a central angle, related to the arc ED, so the arc ED also has 120°.

The angle EFD inscribes the arc ED, so we have:

$mEFD = mED/2$

$mEFD = 120/2 = 60\°$

So the angles mEFD and mEGD are equal. The statement is TRUE.

2. mEGD = mECD

This statement is FALSE, because mEGD = 60° and mECD = 120°

3. mED = mFD

If mED is 120° and mEF = mFD, we have:

$mED + mEF + mFD = 360$

$2*mFD = 360 - 120$

$mFD = 120\°$

So the statement is TRUE, both arcs have 120°.

4. mEF = 60°

This statement is FALSE, because we calculated before that mEF = mFD = 120°

5. mFD = 120°

This statemente is TRUE, because we calculated before that mFD = 120°.

So the correct statements are 1, 3 and 5
