Answer:
48 days
Step-by-step explanation:
Given that :
30 men can ado a piece of work in 40 days
Assume they work at the same rate, then we it means that ;
1 man will take (30 * 40) = 1200 days to finish the work
Reducing 5 men, means we now have (30 - 5) = 25 men
If ;
1 man takes 1200
25 men will take ;
1200 / 25
= 48 days
1. A tourist sights the Hancock tower from the highway with an angle of elevation of 12°. If the
Hancock tower is known to be 1350 feet high, how far away is the tourist, to the nearest tenth?
Answer: [tex]6351.25\ ft[/tex]
Step-by-step explanation:
Given
Angle of elevation [tex]x=12^{\circ}[/tex]
Height of tower [tex]h=1350\ ft[/tex]
Suppose tourist is d feet away from the tower
from the figure, we can write
[tex]\Rightarrow \tan 12^{\circ}=\dfrac{1350}{d}\\\\\Rightarrow d=\dfrac{1350}{\tan 12^{\circ}}=6351.25\ ft[/tex]
Thus, the distance of tourist from the tower is [tex]6350.25\ ft[/tex]
What is the measure of angle C
Answer:
41
Step-by-step explanation:
In order to find the measure of angle C we must find the value of x
Remember the measures of the angles in a triangle add up to equal 180
that being said we use this equation to solve for x
180 = (sum of angles) 63 + 2x + 8 + x + 7
now we solve
step 1 combine like terms
63 + 7 + 8 = 78
2x + x = 3x
now we have 180 = 78 + 3x
step 2 subtract 78 from each side
180 - 78 = 102
78 - 78 cancels out
now we have 102 = 3x
step 3 divide each side by 3x
102/3=34
3x/3=x
we're left with x = 34
Now to find the measure of angle C
We plug in the value of x in the expression (x + 7)
so c = 34 + 7
34 + 7 = 41
therefore your answer is 41

Answer:
____1260 ____Since we have to predict, we can use ratios to help us solve this.
12 said yes out of 72 randomly chosen, SO,
if 210 would say yes (goes to play), how many is total??
12 is to 72 AS 210 is to HOW MUCH (let it be x)??
We can setup ratio, cross multiply, and solve for x:
= 12/72= 210/x
= 12x = 210*72
=12x = 15,120
=x = 15,120/12
=x =1260what is the value of d to the nearest hundredth
Step-by-step explanation:
This can be done by using the trignometric ratio of tangent in the ∆DEF . The two of its sides along 90° are 7.2 and d .
• In ∆ DEF :-
[tex]\tt\to tan42^o = \dfrac{EF}{ED}\\\\\tt\to tan42^o =\dfrac{d}{7.2}\\\\\tt\to 0.9 = \dfrac{d}{7.2}\\\\\tt\to d =7.2\times 0.9\\\\\tt\to\boxed{\orange{\tt d = 6.48 }}[/tex]

The lateral surface area of the triangular prism is 128 square centimeters. The correct answer would be an option (G) 128 cm².
What is the triangular prism?A triangular prism is a three-sided prism consisting of a triangular base, a translated duplicate, and three faces connecting similar sides.
As per the question, we have dimension are:
side legth of base = 6 cm, 5 cm, and 5 cm
height = 8 cm
Lateral surface area = (a+b+c)h
Substitute the values and we get
Lateral surface area = (6+5+5)8
Lateral surface area = 16 × 8
Lateral surface area = 128 cm².
Hence, the lateral surface area of the triangular prism is 128 square centimeters.

Eunice wanted to save up for a mountain bike that costs £250. She baby-sits each week for 6 hours for £2.75 an hour, and does a Saturday job that pays £27.50. She saves 3/4 of her weekly earnings. How many weeks will it take her to save enough to buy the bike?
Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
Assuming she works for 6 days
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount
