PLS HELP IM DESPERATE

Mathematics
1 answer:
katovenus [111]3 years ago
5 0

Answer:

24 square units

Step-by-step explanation:

The area of a parallelogram is given by the formula ...

A = bh

where A represents the area, b the length of the "base", and h the "height" measured at right angles to the base.

Here, it is convenient to use one vertical side of the figure as the base. You can count the grid squares to see that it is 8 units long.

The height is then the distance from one vertical side to the other. Again, you can count the grid squares to see that it is 3 units.

The area is the product of these dimensions:

A = (8 units)·(3 units) = 24 units^2

The probability that it will snow on the last day of January is 85%. If the probability remains the same of the first eight day
MrRa [10]

Answer:

Here, we have:

P(5 days snow in this 8 days) = 8C5 x (0.85)^5 x (1 - 0.85)^3 = 0.084

P(6 days snow in this 8 days) = 8C6 x (0.85)^6 x (1 - 0.85)^2 = 0.238

P(7 days snow in this 8 days) = 8C7 x (0.85)^7  x (1 - 0.85)^1  = 0.385

P(8 days snow in this 8 days) = 8C8 x (0.85)^8 x (1 - 0.85)^0 = 0.272

Add up those above, then the probability that it will snow AT LEAST five of those days in February:

P = 0.084+ 0.238 + 0. 385 + 0.272 = 0.979

Hope this helps!

You want to cover a circular clock in fabric. If the radius of the clock is 6 inches. then how many square inches of fabric will
Airida [17]

Answer:

18.84

Step-by-step explanation:

To find the diameter of an question, multiple the radius by 2, since the radius always covers half of the circular clock. Then multiple 12 x pi = 18.84.

(pi = 3.14)

In the figure CD is the perpendicular bisector of AB . If the length of AC is 2x and the length of BC is 3x - 5 . The value of x
Dennis_Churaev [7]

Answer

Find out the value of x .

To proof

SAS congurence property

In this property two sides and one angle of the two triangles are equal.

in the Δ ADC and ΔBDC

(1) CD = CD (common side of both the triangle)

(2) ∠CDA = ∠ CDB = 90 °

( ∠CDA +∠ CDB = 180 ° (Linear pair)

as given in the diagram

∠CDA  = 90°

∠ CDB = 180 ° - 90°

∠ CDB = 90°)

(3) AD = DB (as shown in the diagram)

Δ ADC ≅ ΔBDC

by using the SAS congurence property .

AC = BC

(Corresponding sides of the congurent triangle)

As given

the length of AC is 2x and the length of BC is 3x - 5 .

2x = 3x - 5

3x -2x =5

x = 5

The value of x is 5 .

Hence proved
