Find the missing length of the triangle. If necessary, round your answer to the nearest tenth
Answers
Answer:
30
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem to find the missing side
a^2 +b^2 = c^2 where a and b are the sides and c is the hypotenuse
x^2 + 40^2 = 50^2
x^2 +1600 = 2500
x^2 = 2500-1600
x^2 = 900
Take the square root of each side
sqrt(x^2) = sqrt(900)
x = 30
Answer:
x = 30
Step-by-step explanation:
[tex]a^{2} = c^{2} - b^{2}[/tex]
[tex]a^{2} = 50^{2} - 40^{2}[/tex]
[tex]a^{2} = 2500 - 1600[/tex]
[tex]a^{2} = 900[/tex]
[tex]\sqrt{a^{2}} = \sqrt{900}[/tex]
a = 30

Two ships are near a buoy in the open ocean. One ship is 20 km due north of the buoy, and the other ship is 13.5 km due east of the buoy.
Round the answer to the nearest tenth.
Answers
Answer:
24 km is your answer
Step-by-step explanation:
Let x be the distance between the two ships.
Hypotenuse side = x km
Adjacent side = 13.5 km
Perpendicular side = 20 km
by using Pythagoras theorem:
x²= 13.5²+ 20²=582.25
x=√ 582.25
х =24.129857024 km
Therefore, the distance between two ships to the nearest tenth place is, 24.1 km

The time t required to do a job varies inversely as the number of people working. It takes 4 hr for 7 cooks to prepare the food for a wedding rehearsal dinner. How long will it take 8 cooks to prepare the dinner?
Answers
9514 1404 393
Answer:
3 1/2 hours
Step-by-step explanation:
If there are 8/7 times as many cooks, it will take 7/8 the amount of time. (That's what "inversely proportional" means.)
(7/8)(4 h) = 28/8 h = 3 1/2 h
It will take 8 cooks 3 1/2 hours to prepare the dinner.

A florist sold 14 flower bouquets yesterday, including 7 lily bouquets. Based on past data, how many of the next 20 bouquets sold should you expect to be lily bouquets?
Answers
Answer:
10
Step-by-step explanation:
From past data:
Fraction of lily sold :
Total flowers / number of lily
Total flowers = 14
Number of lily = 7
Fraction of lily = 14 /7 = 1/2
Going by these ;
Expected number of lilies in the next 20 bouquets sold :
Fraction of lily * number of flower in bouquet
1/2 * 20
= 10 lilies

Remy stands on a dock at the edge of the lake represented by point C. Points A and B represent two buoys anchored in the lake. Remy plans to swim from C to A, then to B and then back to C. The shortest distance from Remy to the swim route AB is 60 meters and is measured from C to D.
What is the total distance, in Meters that Remy will swim? Round your number to the nearest whole number.
Answers
*see attachment for the diagram and more info
Answer:
236 m
Step-by-step explanation:
Total distance Remy will swim = CA + AD + DB + BC
✔️Find AD and CA using trigonometry function:
Reference angle = 43°
Opp = AD
Hypotenuse = CA
Adjacent = 60 m
Tan 43 = opp/adj
Tan 43 = AD/60
60 × Tan 43 = AD
60 × 0.93 = AD
55.8 = AD
✅AD = 55.8 m
Cos 43 = adj/hyp
Cos 43 = 60/CA
CA × Cos 43 = 60
CA = 60/Cos 43
CA = 60/0.73
✅CA ≈ 82.2 m
✔️Find DB and BC:
Refernece angle = 27°
Adj = 60 m
Opp = DB
hyp = BC
Tan 27 = opp/adj
Tan 27 = DB/60
60 × Tan 27 = DB
60 × 0.51 = DB
✅DB = 30.6 m
Cos 27 = adj/hyp
Cos 27 = 60/BC
BC = 60/Cos 27
BC = 60/0.89
✅BC ≈ 67.4 m
✔️Total distance Rent will swim = 55.8 + 82.2 + 30.6 + 67.4 = 236 m

Answer: The given equation is
And we have to solve for w .
For that we first get rid of y. And for that, we subtract y from both sides,
Now we need to separate v from w square, and for that, we divide both sides by v, that is
Now to get rid of square, we take square root to both sides. That is
And that's the required answer.

Step-by-step explanation:
6-12=6 (total cm of the bases for triangle B and C)
6/2= 3 (base of B and C trialngleis 3 )
Triangle formula: bh 1/2

A cereal box has a surface area of 280 square inches. What is the surface are of a similar box that is larger by a scale factor of 1.4 ?
Answers
Answer: 548.8 square inches
Step-by-step explanation:
From the question, we are informed that a cereal box has a surface area of 280 square inches.
The surface area of a similar box that is larger by a scale factor of 1.4 will be gotten by multiplying 280 by the scale factor's square. This will be:
= 280 × (1.4)²
= 280 × 1.96
= 548.8 square inches

In a fruit cocktail, for every 20 ml of orange juice you need 10 ml of apple juice and 15 ml of coconut milk. What proportion of the cocktail is apple juice?
Give your answer as a fraction in its simplest form.
Answers
Answer:
5/9
Step-by-step explanation:
First, find the total number of mL in the drink:
20 + 10 + 15
= 45
There are 10 mL of apple juice, so the proportion will be 10/45
Simplify this by dividing the numerator and denominator by 5:
10/45
= 5/9
So, 5/9 is the proportion of the cocktail that is apple juice
Which rule describes the x-coordinates in the translation below?.
x + 0
x + 6
x – 6
x + 2
Answers
Answer:
A) x + 0
Step-by-step explanation:
In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)
In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)
Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.
Therefore, the rule for x-coordinates = x + 0
Answer: A) x + 0
