Answer:

B

Step-by-step explanation:

There are 12 inches in 1 feet, so

5 feet = 5 * 12 = 60 inch

6 feet = 6 * 12 = 72 inch

So, we can say most adult humans are between 60 to 72 inches tall

The model is 7 inches tall. So, from the answer choices, 7 * 10 = 70 [the number that is in between 60 to 72]. Thus we can take the model to be 1/10th of the original.

So the scale factor is 1/10, or option B

Semmy [17]

Answer:

Total = \frac{1}{2}

Step-by-step explanation:

Given

Carol = \frac{1}{8}

Luke = \frac{3}{8}

Required

How far did they row together

To do this, we simply add the distance they both covered.

Total = Carol + Luke

This gives;

Total = \frac{1}{8} + \frac{3}{8}

Take LCM

Total = \frac{1+3}{8}

Total = \frac{4}{8}

Simplify

Total = \frac{1}{2}

<em>Hence, they both rowed 1/2 mile</em>

Find the measure of MNQ
xz_007 [3.2K]

Answer:

m∠MNQ = 158

Step-by-step explanation:

As it can be seen in the figure:

+) The measure of arc MQ = 91 degree

+) The measure of arc RP = 225 degree

As this is the circle, four points M, Q, P and R are on the circle, so that we have:

+) m∠RMP = 1/2. measure of arc RP = 1/2 x 225 = 112.5 degree

As N is on MP

=> m∠RMN = m∠RMP = 112.5

+) m∠ MRQ = 1/2 measure of arc MQ = 1/2 x 91 = 45.5 degree

As N is on RQ

=> m∠MRN = m∠MRQ = 45.5

In the triangle RMN, the total measure of 3 internal angles is equal to 180 degree, so that:

m∠MNR + m∠RMN + m∠MRN = 180

=> m∠MNR + 112.5 + 45.5 = 180

=> m∠MNR  = 180 -112.5 -45.5 = 22

As N is on QR

=> m∠MNR + m∠MNQ = 180

=> m∠MNQ = 180 - m∠MNR  = 180 - 22 = 158

So that m∠MNQ = 158

Complete the table of values for y = - x2 - 6x - 4
Anna11 [10]

Answer:

x= -2 —> y= 4

x = -1 —> y = 1

x = 0 —> y = – 4

x = 1 —> y = – 11

x = 2 —> y = – 20

I hope I helped you^_^

OLga [1]
The correct answer is 4x2 + 22x − 1 = 0

That's what you get when you (5 + 2x)(6 + 2x) = 31

And you get to expand that based on the data that is already provided in the question.
