in triangle ABC shown below, L is the midpoint of BC, M is the midpoint of AB, and N is the midpoint of AC. Find the perimeter of trapazoid BMNC.

In Triangle ABC Shown Below, L Is The Midpoint Of BC, M Is The Midpoint Of AB, And N Is The Midpoint

Answers

Answer 1

35

since m and n are the midpoints of ab and ac resistively

then ,bc=2mn=16

since m and l are the midpoints of ba and bc respectively

then, ac =2mn =10

then,nc =1/2 × 10 =5

similary, mb=6

then ,perimeter=nc+mb+mn+bc=5+6+8+16=35

Answer: for plato users

D. 341  and 375

Step-by-step explanation:

I just took the test

The approximate 95% confidence interval for Swapna's page views is [341, 375].

What is confidence interval?It is a range of values that's likely to include a population value with a certain degree of confidence. It is expressed as a percent (%) where a population mean lies between an upper and lower interval.A confidence interval is how much uncertainty is with any particular statistic.When it is a 95% confidence interval, it means a range of values that you can be 95% certain contains the true mean of the population.A confidence interval is obtained from the observed data that holds the actual value of the unknown parameter.Formula of confidence interval:

Confidence interval =  mean ± Z * (standard deviation/ √sample size)

For given question,

Sample size = 40

Sample mean = 358

Standard deviation = 54.3

Critical value at 95% confidence level= 1.96

Confidence interval = 358 ± 1.96 * (54.3/ √40)

                                  = [358 - 1.96 * (54.3/ √40) ,358 + 1.96 * (54.3/ √40)]

                                  = [341, 375] (approximately)

Find the slope of a line that goes through the points (5,-2) and (1,0).
A. 1/2 B. - 1/2 C. 2 D. -2

Answers

Answer:

B(-1/2)

Step-by-step explanation:

So remember, the slope is y2-y1/x2/x1. Note that y2 means the second y adn x2 means the second x.

So lets plug in our numbers for the top of our fraction, y2-y1. This is 0- - 2.

You should get postive 2, since -- equals a + so it would be 0+2 equaling 2.

This is your y value of your slope.

Next lets find the x value of the slope.

Lets plug in our numbers for the bottem raction this time, which is x2-x1. This is 1-5.

You should get negative 4, since 1-5 equals -4.

This is the x value of the slope.

Knowing your y and x value of the slope, we can tell that the slope will be:

2/-4

This can be simplyfied to -1/2. Since 2 goes into 2, 1 time(for y). Then 2 goes into -4, -2 times(for x). So now its 1/-2.

The negative sign can just be moved to the front since it is the only negative and does not change:

Bob wants to buy a car. He puts $8,000 in a savings account that has a

D-$320

Answers

9514 1404 393

Answer:

  B.  $8,960

Step-by-step explanation:

Use your number sense.

If the account earns interest, the balance will increase from the initial deposit of $8000. The only sensible answer choice is B, $8960.

__

If you want to actually figure it out, the balance is given by ...

  A = P(1 +rt)

  A = 8000(1 +0.04·3) = 8000(1.12) = 8960 . . . . matches choice B

angle A and angle B are complementary. Find angle A and angle B.
angleA = (3x + 46)°
angleB = (x − 4)°

Answers

Answer:

Angle A is 82

Angle B is 8

Step-by-step explanation:

Complementary means they add to 90 degrees

3x+46+x-4=90

4x+42=90

4x=48

x=12

Angle A is 3(12)+46= 82

Monique and Tara each make an ice-cream sundae. Monique gets 2 scoops of Cherry ice-cream and 1 scoop of Mint Chocolate
Chunk ice-cream for a total of 71 g of fat. Tara has 1 scoop of Cherry and 2 scoops of Mint Chocolate Chunk for a total of 73 g of
fat. How many grams of fat does 1 scoop of each type of ice cream have?

Answers

Answer:

the number of grams in cherry ice cream and mint chocolate is 23 grams fat and 25 grams fat respectively

Step-by-step explanation:

Let us assume the number of grams in cherry ice- cream be x

And, the number of grams in mint chocolate be y

Now as per the question

The following equations should be used

2x + y = 71  ................... (1)

x  + 2y = 73.................(2)

Multiply 2 in equation 1

So,

4x + 2y = 142

x + 2y = 73

3x = 69

x = 23 grams fat

And, y is

2(23) + y = 71

y = 25 grams fat

hence, the number of grams in cherry ice cream and mint chocolate is 23 grams fat and 25 grams fat respectively

What is the volume of a hemisphere with a radius of 3.1 in, rounded to the nearest tenth of a cubic inch?

Pls help me

Answers

Answer:

Formula: V = (2/3) π r 3.

Radius is 3cm.

So, now we can plug it in to solve for the volume.

V = (2/3) π 3^3

First, let's multiply 3^3.

3^3 = 27

Then, 27 x π = 84.82

After, multiply by 2/3.

84.82 x 2/3 = 56.55

Lastly, round 56.55 to the nearest tenth of a cubic centimeter.

56.55 = 56.6

Therefore the volume of a hemisphere with a radius of 3cm is 56.6cm^3.

Step-by-step explanation:
