Answer:
40
Step-by-step explanation:
*this is a 90 degree triangle
so we will use Pythagorean theorem to get X
hypotenuse²=side of right triangle²+the other side of right triangle²
so
50²=30²+x²
2500=900+X²
2500-900=x²
1600=x²
x=√1600
=40
so the answer is 40

In circle B with the measure of minor arc AC= 84°, find m
Answers
Answer:
m<ADC = 42°
Step-by-step explanation:
Based on the inscribed angle theorem, the inscribed angle, m<ADC is ½ the measure of minor arc AC.
If minor arc is given as 84°, therefore:
m<ADC = ½(84)
m<ADC = 42°
Water is flowing from Tank #1 to Tank #2 as shown in the picture. Originally, Tank #1 had 1,540 gallons in it and Tank 2 had 236 gallons in it. Water is draining out of Tank #1 at a ate of 6 gallons per minute and, thus, filling Tank #2 up at a ate of 6 gallons per minute. ) Write an equation for each tank that models the volume of water, v in gallons, as a function of the number of minutes, m, that the water has been flowing. Tank #1: Tank #2: Find out how long it takes, to the nearest minute, for the two tanks to have Will it take longer or shorter than 2 hours? Justify.
Answers
Answer:
Melody, think about this as below
Step-by-step explanation:
when does tank 1 = tank 2 when there is 6 gpm
tank 1 = 1540
tank2 = 236
1540-6x = 236 +6 x
1304 = 12x
108 [tex]\frac{2}{3}[/tex] = x
6*108 [tex]\frac{2}{3}[/tex] = 652 gallons
236+652=888
1504-652=888
in 108 [tex]\frac{2}{3}[/tex] minutes the tanks become equal with 888 gallons each :)

Answers
Complete question :
A textile fiber manufacturer is investigating a new drapery yarn, which the company claims has a mean thread elongation of 12 kilograms with a standard deviation of 0.5 kilograms. The company wishes to test the hypothesis H0 : μ = 12 against H1 : μ < 12 using a random sample of n = 4 specimens. Calculate the P-value if the observed statistic is xbar = 11.5. Suppose that the distribution of the sample mean is approximately normal.
Answer:
0.02275
Step-by-step explanation:
Given :
Population mean μ = 12
Standard deviation, σ = 0.5
Sample size, n = 4
Observed statistic, xbar = 11.5
H0 : μ = 12
H1 : μ < 12
The test statistic = (xbar - μ) ÷ σ/sqrt(n)
Test statistic =. (11.5 - 12) ÷ 0.5/sqrt(4)
Test statistic = - 0.5 ÷ 0.5/2
Teat statistic = - 0.5 / 0.25 = - 2
Since, it is stated that, distribution is approximately normal ; then we can use the Z distribution and obtain our Pvalue.
We could obtain P value using the Pvalue Z distribution calculator at α = 0.05, 1 - tail
Pvalue = 0.02275
Or
P(x < - 2) = 0.02275 (Z distribution table)

Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef y=what.
Answers
Answer:
88
Step-by-step explanation:
The total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.
What is the total cost?Total cost or the final cost is the summation of all the cost spend while buying any good or taking any service.
Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef.
In this problem, the total cost y has to be found out. As the price of one pound of ground beef is $22 and there is total 4 pounds of ground beef, Cami bought.
Thus, the total cost is,
[tex]y=22\times44\\y=88[/tex]
Thus, the total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
10
6
Can somebody please help me
Answers
Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
For the semicircle with radius = [tex]\frac{6}{2}[/tex] = 3 units
Area = [tex]\frac{1}{2}\pi (3)^{2}[/tex]
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units

Joe went on holiday to Spain.
His flights cost a total of £320
Joe stayed in an apartment for 3 weeks.
The apartment cost 560 euros each week.
Joe hired a car for 15 days.
The car hire cost 20.16 euros each day.
The exchange rate was £1 = 1.12 euros.
(a) Work out the total cost, in pounds, of the flights, the apartment and the car hire.
(b) If there had been more than 1.12 euros to £1, how would this affect your answer
to part (a)?
(2 part question; enter answers for (a) and (b) in the answer box below) *
(5 Points)
Answers
a. £2,090
b. My answer would be less because my total in euros would be divided by a greater number when converting euros to pounds.
Work for part a:
Apartment: 560•3= 1680 euros
Car: 20.16•15= 302.4 euros
1680+302.4=1982.4
1982.4/1.12 = £x/1
1982.4 / 1.12= £1,770
£1,770 + £320 = £2,090 total
Work for part b:
Example:
(instead of 1.12 I put 2 to see what would happen with a greater number)
1982.4 / 2 = 991.2
991.2 is less than 1,770 (the answer I got with 1.12)
