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
help pls What is the measure of ∠x
Angles are not necessarily drawn to scale. Given the following:
Answer: 31
Step-by-step explanation:
assuming lines DE and FG are parallel, <jcg and <DAL are alternate exterior angles, so they are congruent.
<DAK is 90
so the measure of <x=90-59
x=31
In which step does a mistake first occur?
(24+3 + 10)-14 +2
Step 1: (8 + 10) -14 + 2
Step 2: 18 -14+2
Step 3: 4+2
Step 4: 2
Answer:
The step that a mistake first occurs is in step 1.
Step-by-step explanation:
In step one, the constants in the parenthesis went from 24 + 3 + 10 to 8 + 10, which is essentially impossible, so step 1 was the step where a mistake first occurred.

Swapna gathered data on the number of page views for each of her blog posts. For her 40 latest posts, she found a sample mean of 358 with a population standard deviation of 54.3. What is the approximate 95% confidence interval for her page views? HINT: It's not D.
A. 344 and 372
B. 356 and 360
C. 341 and 375
D. 336 and 380
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)

Bob wants to buy a car. He puts $8,000 in a savings account that has a
simple interest rate of 4%. If he leaves his money in the account for 3
years, how will be in his account in TOTAL after 3 years?"
A-$960
B-8,960
C-7,040
D-$320
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
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
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.

angle A and angle B are complementary. Find angle A and angle B.
angleA = (3x + 46)°
angleB = (x − 4)°
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
Angle B is 12-4=8
82+8=90
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
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:
Answer:
-1/2

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?
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
