The answer would be 40 because if you take the the line in which angle b is in it would be 180 and then we would subtract 140 which gives you 40 , good luck ! :)

Find area of the triangle 15ft 10ft 10ft

Answers

Answer:

75

Step-by-step explanation:

i'm going to assume that the base is 10, the formula for a triangle is base x height divided by 1/2 (or 2)

15height x 10base = 150 now divided by 2, 150/2 = 75

The density of water is 1000 kilograms per cubic meter and the density of ice is about 916 kilograms per cubic meter of 700 kilograms of water and 450 kilograms of ice is combined in a container what is the volume of the water

Answers

Final answer:

The volume of water can be calculated by dividing the mass of water by the density of water.

Explanation:

The question asks for the volume of water when 700 kilograms of water and 450 kilograms of ice are combined in a container. To find the volume of water, we need to subtract the volume of ice from the total volume. The density of water is 1000 kg/m³, so the volume of water can be calculated by dividing the mass of water (700 kg) by the density of water (1000 kg/m³).

Volume of water = Mass of water / Density of water

Volume of water = 700 kg / 1000 kg/m³

Volume of water = 0.7 m³

Is LNM =(~) OQP? If so, name the postulate that applies.

Answers

Answer:

The postulate that applied if $$\triangle L N M \cong \triangle O Q P$$ is an option (b) Congruent -ASA.

Step-by-step explanation:

What is Congruent -ASA?

By the Congruent -ASA rule, two angles in one triangle are congruent with two angles in a second triangle, and if the sides included in both triangles are also congruent, then the triangles are congruent.

Determine the postulate if  $$\triangle L N M \cong \triangle O Q P$$:

Given:

&\overline{\mathrm{LM}} \cong \overline{\mathrm{OP}} \n

&\overline{\mathrm{MN}} \cong \overline{\mathrm{PQ}} \n

&\angle \mathrm{M} \cong \angle \mathrm{P}

Here, the answer is obvious from the question,

\angle \mathrm{M} is LM and MN's Angle.

$\angle P$ is PQ and PO's Angle.

Hence, it is ASA.

So, if the angle $$\triangle L N M \cong \triangle O Q P$$, then the postulate that is applied is Congruent -ASA.

Which one of the following is a Geometric Sequence?

Answers

Answer:

The geometric sequence among following is:

         Option: B

         8 , 4 , 2 , 1 , 1/2 , 1/4 ,.....

Step-by-step explanation:

Geometric sequence--

A sequence is said to be a geometric sequence if each of the number in the sequence is a constant multiple of the preceding term in the sequence.

This constant multiple is known as the common ratio (r)

i.e. the sequence is given by:

a,ar,ar²,ar³,.....

A)

0,1,2,3,......

It is a arithmetic sequence and not a geometric sequence .

Since, each of the term is increasing by 1 as compared to the preceding term of the sequence.

B)

8,4,2,1,1/2,1/4,.....

It is a geometric sequence.

Since, each term of the sequence is a constant multiple of 1/2 of the preceding term of the sequence.

i.e. 8×(1/2)=4

4×(1/2)=2

2×(1/2)=1

1×(1/2)=1/2

and so on.

i.e. the common ratio is: 1/2

C)

-7,10,23,36,.....

This is not a geometric sequence.

Since,

-7* (-10)/(7)=10

but

10* (-10)/(7)\neq 23

D)

2,-3,9/2,-18/4

Here

2* (-3)/(2)=-3

-3* (-3)/(2)=(9)/(2)

but

(9)/(2)* (-3)/(2)=(-27)/(4)\neq (-18)/(4)

Hence, it is not a geometric sequence.
