Michael draws three parallelograms. In each figure, he measures a pair of angles, as shown.

Phoenix [80]

we know that

In parallelogram, the sum of consecutive angles are 180

so, consecutive angles are supplementary

And opposite angles are equal

so, we will check verify each options

option-A:

Since, consecutive angles are supplementary

so, this is FALSE

option-B:

Since, only opposite angles are equal or congruent

so, this is FALSE

option-C:

Since, consecutive angles are supplementary

so, this is TRUE

option-D:

Since, consecutive angles are supplementary

so, this is FALSE

Denver is planting strawberry seedlings in a new garden. He can plant 3 rows of a certain length with 2 seedlings leftover or 4

Deffense [45]

Given:

Denver can plant 3 rows of a certain length with 2 seedlings leftover or 4 rows of the same length with 3 seedling spots left empty.

To find:

The equation for the given problem and its solution.

Solution:

Let x be the length of each row.

Denver can plant 3 rows of a certain length with 2 seedlings leftover.

Total number of seeds he has = $3x+2$ ...(i)

Denver can plant 4 rows of the same length with 3 seedling spots left empty.

Total number of seeds he has = $4x-3$ ...(ii)

Using (i) and (ii), we get

$3x+2=4x-3$

Isolate variable terms.

$2+3=4x-3x$

$5=x$

Therefore, the required equation is $3x+2=4x-3$ and the values of x is 5. Each row is 5 meters long.

A large storage tank, open to the atmosphere at the top and filled with water, develops a small hole in its side at a point 10.4

vlabodo [156]

Answer:

Therefore the diameter of the hole is $1.94 \times 10^{-3}$ m.

Step-by-step explanation:

Bernoulli's equation,

$P_1+\frac12 \rho v^2_1+\rho g h_1= P_2+\frac12 \rho v^2_2+\rho g h_2$

P₁ = P₂= atmospheric presser

$\rho$ = density

$\frac12 \rho v^2_1+\rho g h_1= \frac12 \rho v^2_2+\rho g h_2$ [since P₁ = P₂]

$\Rightarrow\rho (\frac12 v^2_1+ g h_1)= \rho(\frac12 v^2_2+ g h_2)$

$\Rightarrow\frac12 v^2_1+ g h_1= \frac12 v^2_2+ g h_2$

$\Rightarrow\frac12 v^2_2-\frac12 v^2_1=g h_1- g h_2$

$\Rightarrow v^2_2- v^2_1=2g h$ [ $h_1-h_2=h$ ]

Here $v_1\approx 0$

$\Rightarrow v^2_2=2g h$

$\therefore v_2=\sqrt {2gh$

Here g= 9.8 m/s² , h = 10.4 m

The velocity of water that leaves from the hole $v_2$ = $\sqrt {2\times 9.8\times 10.4}$ m/s

=14.28 m/s.

Given, the rate of flow from the leak is $2.53\times 10^{-3}$ $m^3/min$

$=\frac{2.53\times 10^{-3}}{60}$ $m^3/s$

Let the diameter of the hole be d.

Then the cross section area of the hole is $=\pi (\frac d2)^2$

We know that,

The rate of flow = Cross section area × speed

$\Rightarrow \frac{2.53\times 10^{-3}}{60} =\pi (\frac d2)^2\times 14.28$

$\Rightarrow (\frac d2)^2=\frac{2.53\times 10^{-3}}{60\times 14.28\times \pi}$

$\Rightarrow d= 1.94 \times 10^{-3}$

Therefore the diameter of the hole is $1.94 \times 10^{-3}$ m.

the russian ice breaker Yamal can move forward through 2.3 meter 2.3 meter thick ice at a speed 5.5 kilometers

morpeh [17]

Answer:

Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.

Step-by-step explanation:

Given:

Speed = 5.5 km/hr

Distance = 82 km

Let time be represented as 'x'.

We need to find the number of hours required to travel 82 km.

We know that Distance can be calculated by the product of Speed and time.

Framing above sentence in equation form we get;

Distance = Speed × Time

Substituting the given value we get;

$82 = 5.5x$

Hence The expression for number of hours is $82 = 5.5x$

Solving the equation to find the value of x we get;

$82 = 5.5x\\\\x=\frac{82}{5.5} = 14.90 \approx 15\ hrs$

Hence Yamal can move the ice to 82 km in approximately <u>15 hrs</u>.
