Question two
The lengths of the sides of a triangle are in the ratio 2:3:4. The shortest side is 14cm long.
Find the lengths of the other two sides​

Answers

Answer 1

Answer:

14 and 21 and 28

Step-by-step explanation:

2:3:4.

The shortest side is 14

14/2 = 7

Multiply each side by 7

2*7:3*7:4*7

14 : 21 : 28

Answer 2
Triangle are in the ratio 2:3:4.

2x =5

x = 5/2 = 2.5 cm

3x = 3(2.5) =7.5 cm
4x =4(2.5) =10.0 cm

Answers

Answer:

48

Step-by-step explanation:

.08x600=48

Answer:

Step-by-step explanation:

total patients = 600

% of patients had eye surgery = 8%

Number of patients that had eye surgery ?= x

% of pt that had eye surgery =  no. of pt that had surgery/ total number of pt

Answer:

a = 4[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos60° = [tex]\frac{1}{2}[/tex] , then

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{2\sqrt{3} }{a}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

a = 4[tex]\sqrt{3}[/tex]

Suppose scores on exams in statistics are normally distributed with an unknown population mean and a population standard deviation of three points. A random sample of 36 scores is taken and gives a sample mean of 68. Find a 85 % confidence interval estimate for the population mean exam score. Explain what the confidence interval means​

Answers

this the answer of queastions

Step-by-step explanation:

67.18,68.82

Let mu be the true population mean of statistics exam scores. We have a large random samples of n=36 scores with a sample mean of 68.we know that the population standard deviation is sigma=3.A pivotal quantity is 3^sqrt(36)=(3/6)=68(1/2) which is approximately normally distributed. Therefore the 85%confidence interval is 68-(1/2)(1.6449), 68+(1/2)(1.6449) i.e (67.18,68.82)

Step-by-step explanation:

The sample size needed to estimate the difference between two population proportions to within a margin of error E with a significance level of ? can be found as follows. In the expression
E=z?p1(1?p1)n1+p2(1?p2)n2?????????????????????????
we replace both n1 and n2 by n (assuming that both samples have the same size) and replace each of p1, and p2, by 0.5 (because their values are not known). Then we solve for n, and get
n=(z?)22E2.
Finally, increase the value of n to the next larger integer number.

Answer:

x = 1/2

Step-by-step explanation:

8(-2x+1) =0

Divide each side by 8

-2x+1 = 0

Add 2x to each side

-2x+1+2x = 2x

1 = 2x

Divide by 2

1/2 = 2x/2

1/2 =x

Answer:

1/2

Step-by-step explanation:

8(-2x+1)=0

Use distributive property first

-16x+8=0

Subtract 8 on both sides

-16x=-8

Divide both sides by -16 to get x by itself

x=0.5

Which is also equal to 1/2

Therefore, x is equal to 1/2

Kayla parks her car at the corner of Ogilvie and Montreal Rd. She walks 80m East and then turns 30° to the left towards her office building and continues walking for another 100m until she reaches her building. She then takes the elevator to her office 60m above ground level and looks out the window. She can see her car from here. How far is it from where she is to her car in a direct line?

Answers

9514 1404 393

Answer:

  184 m

Step-by-step explanation:

The direct distance from Kayla's car (C) to the door of her office building (B) can be found using the Law of Cosines. The interior angle of the triangle at the turning point is 180° -30° = 150°, so the distance is ...

  t² = b² +c² -2bc·cos(T)

  t² = 80² +100² -2·80·100·cos(150°) = 30256.406

The direct distance from her window to the car can be found from the Pythagorean theorem. The legs of the right triangle are the distance from the car to the building (CB) and the height from the building entrance to the window (BW).

  CW = √(t² +60²) ≈ 184.001

The direct line distance from Kayla to her car is 184 meters.

Let the set A be defined as follows.

(a) Find the total number of proper subsets of A.


(b) Find the total number of subsets of A.

Answers

Answer:

(a) 31

(b) 32

Step-by-step explanation:

We will do (b) first since it will help us do (a).

(b)

There are [tex]n(A)=5[/tex] elements in [tex]A[/tex]. Using the formula for the number of subsets of a given (finite) set, the number of subsets of [tex]A[/tex] is

[tex]2^{n(A)}=2^5=32[/tex]

(a)

A subset of [tex]A[/tex] is called proper if it does not equal [tex]A[/tex]. The only subset of [tex]A[/tex] that is not proper is [tex]A[/tex] itself, so simply subtract 1 from the number of subsets to get the number of proper subsets, which is

James purchased five acres of land fo 75,000 what was the cost per acre

Answers

Answer:

$15,000

Step-by-step explanation:

James purchased a total of 5 acres of land for a total price of $75,000. To find the cost of each individual acre, simply divide the total cost with the total amount of acres purchased:

[tex]\frac{total price of land bought}{total amount of acres} = \frac{75000}{5} = 15000[/tex]

The cost per individual acre, assuming all of them cost the same, is $15,000.

~

Answer:

15000

Step-by-step explanation:

Since

5 acres = 75000

therefore,

the cost price per acre would be

total cost price ➗ 5

7500/5= 15000

Select the correct text in the passage.Which sentence in the excerpt best supports the theme of harmonious living?A Spark Neglected Burns the Houseby Leo Tolstoy (adapted excerpt)There once lived in a village a peasant named Ivn Stcherbakf. He was comfortably off, in the prime of life, the best worker in the village, andhad three sons all able to work. The eldest was married, the second about to marry, and the third was a big lad who could mind the horses andwas already beginning to plough. Ivn's wife was an able and thrifty woman, and they were fortunate in having a quiet, hard-working daughter-in-law. There was nothing to prevent Ivn and his family from living happily. They had only one idle mouth to feed; that was Ivn's old father,who suffered from asthma and had been lying ill for seven years. Ivn had all he needed three horses and a colt, a cow with a calf, and fifteensheep. The women made all the clothing for the family, besides helping in the fields, and the men tilled the land. They always had grain enoughof their own to last over beyond the next harvest and sold enough oats to pay the taxes and meet their other needs. So Ivn and his childrenmight have lived quite comfortably had it not been for a feud between him and his next-door neighbor, Limping Gabriel, the son of GordyIvnof.As long as old Gordy was alive and Ivn's father was still able to manage the household, the peasants lived as neighbors should. If the womenof either house happened to want a sieve or a tub, or the men required a sack, or if a cart-wheel got broken and could not be mended at once,they used to send to the other house, and helped each other in neighborly fashion. When a calf strayed into the neighbor's thrashing-ground,they would just drive it out, and only say, "Don't let it get in again, our grain is lying there." And such things as locking up the barns andouthouses, hiding things from one another, or backbiting were never thought of in those days.That was in the fathers' time. When the sons came to be at the head of the families, everything changed. If you dissolve 0.1 mol of formic acid in 1 L of water, ther esulting solution contains 0.004 mol of HO+.
