Answer:

Choice C.

Step-by-step explanation:

A parallelogram is a quadrilateral with two pairs of opposite parallel sides.

There is a theorem that states that opposite sides of a parallelogram are congruent.

In this case, sides AB and CD are opposite sides.

Sides BC and AD are opposite sides.

Side CD is opposite side AB, so they are congruent.

Answer:

Choice C.

CD = AB; Opposite sides of parallelograms are congruent.

The pipe has a length 29cm, internal diameter 6.5cm and thickness 0.5cm. What is the Volume

Reptile [31]

Answer:

Length of pipe = 21 cm

Internal diameter = 4 cm

Internal radius = \frac{4}{2} = 2 cm24=2cm

Thickness = 0.5 cm

Outer radius = 2+0.5=2.5 cm

Volume of pipe =\pi R^2 h - \pi r^2 hπR2h−πr2h

Volume of pipe =\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3

=\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3722(2.5)2(21)−722(2)2(21)=148.5cm3

Hence The volume is 148.5 cubic cm.

A line tangent to a circle and a radius of the same circle intersect at the point of tangency to create an angle of what measure

aliya0001 [1]

A theorem states that, given a circle with center C and a point P on the circumference, the tangent line through P and the radius CP are perpendicular.

So, the answer is 90 degrees.

Write a function to represent each problem situation Carmen deposits $1000into simple interest account.The rate for the account

kolezko [41]

The function the represent the balance in the account as a function of time t is p(t) = 1000 + 40t

<h3><u>Solution:</u></h3>

Given that,

Carmen deposits $1000 into simple interest account

The rate for the account is 4%

To find: function the represent the balance in the account as a function of time t

Given is simple interest account

The formula for simple interest is given as:

$S.I = \frac{ prt}{100}$

Where, "p" is the principal and "r" is the rate of interest and "t" is the number of years

In simple interest,

total amount after "t" years = principal + simple interest

Here in this question, Carmen deposits $1000

$p_0 = 1000$

$r = 4 \% = \frac{4}{100} = 0.04$

Thus we can frame a function as:

total amount after "t" years = principal + simple interest

$p(t) = p_0 + (p_0 \times r \times t )$

$p(t) = 1000 + (1000 \times 0.04)t\\\\p(t) = 1000 + 40t$

Where, p(t) is the amount after "t" years and $p_0$ is the principal sum

Thus the function is obtained
