Answer:

Answer: A

Step-by-step explanation:

You want to make them both have common denominators. What number does the denominators both go into? Thats easy, its 60.

Multiply 7/12 by 5/5 to get 35/60

Now multiply 4/15 by 4/4 to get 16/60

You need to add a negative number to 35/60 in order to get 16/60

Do 16-35 to get -19/60

Can someone help me with this math problem 26.04 divided by -6.2

Answers

Answer:

-4.2

Step-by-step explanation:

To divide 26.04 by -6.2, you can follow these steps: Multiply both numbers by 10 to eliminate decimal places. Divide the resulting numbers. The answer is 4.24.

To divide 26.04 by -6.2, you can follow these steps:

Multiply both the dividend and divisor by 10 to eliminate the decimal places. You will get -262.4 divided by -62.
Divide the numbers as usual. -262.4 divided by -62 equals 4.24.

Therefore, 26.04 divided by -6.2 is equal to 4.24.

In the diagram shown, M, N and P are collinear and QM=QN as shown. If mMQN = 48" andmNQP = 33. Justify why QNP must be isosceles.

Answers

An isosceles triangle is that the triangle must have two sides of equal length.

Triangle QNP is isosceles triangle because, QN = PN

In triangle QMN,

Since, QM = QN

So, ∠QMN = ∠QNM

By property of triangle:

∠MQN + ∠QNM + ∠QMN = 180

48 + 2 ∠QNM = 180

∠QNM = $(180-48)/(2)$ = 66 degree

So, ∠QMN = ∠QNM = 66 degree

from figure,

∠QNM + ∠QNP = 180

∠QNP = 180 - 66 = 114 degree.

In triangle QNP,

∠QNP + ∠PQN + ∠QPN = 180

∠QPN = 180 - 33 - 114 = 33 degree

Since, ∠QNP = ∠QPN = 33 degree

Therefore, triangle QNP is isosceles triangle.

Answer/Step-by-step explanation:

Let's find the measure of the angles of ∆QNP.

∆QMN is am isosceles ∆, because it has two equal sides. Therefore, its base angles would be the same. Thus:

m<MNQ = ½(180 - 48) (one of the base angles of ∆QMN)

m<MNQ = ½(132) = 66°

Next, find m<QNP

m<QNP = 180° - m<MNQ (linear pair angles)

m<QNP = 180° - 66° (Substitution)

m<QNP = 114°

Next, find m<P

m<P = 180 - (m<QNP + m<PQN) (sum of ∆)

m<P = 180 - (114 + 33)

m<P = 180 - 147

m<P = 33°

Thus, in ∆QNP, there are two equal angles, namely, <P and <PQN.

An isosceles ∆ had two equal base angles. Therefore, ∆QNP must be an isosceles ∆.
