What is the value of y in the triangle?
Answer:
3√3
Step-by-step explanation:
y/sin60° = 6/sin90°
then y = (6×sin60°)/sin90°
=6×sin60°
= 3√3
Answer:
[tex]3\sqrt{3}[/tex]
Step-by-step explanation:
[tex]sin\alpha =\frac{opposite }{hypotenuse} \\sin 60 = \frac{y}{6} \\y=6 * sin60\\y=6*\frac{\sqrt{3} }{2} \\y = 3\sqrt{3}[/tex]
Need help with a few geometry questions !?!?
Answer:
1. ACB, CDB and ADC are all similar to eachother.
2. 10
3. CD=8, AD=10.666667, AC=13.33333
4. X=2.4
5. X=√10
6. X=√15
Step-by-step explanation:
1. To prove triangles are similar, prove they share at least two angles.
Triangle ACB is similar to triangle CDB because they both share a 90° angle and ∠B.
Triangle ACB is similar to triangle ADC because they both share a 90° angle and ∠A.
Since ACB is similar to both CDB and ADC respectively, CDB is similar to ADC.
2. Use similar triangles to find AB
ACB is similar to CDB
AB/CB=CB/DB
AB/10=10/6
AB=100/6=16.666667
Geometric mean: √(16.66667*6)=10
3.
Find CD using Pythagorus:
10²=6²+CD²
CD²=100-36
CD=√64=8
Use similar triangle ratios to find AD:
CDB is similar to ADC.
CD/DB=AD/DC
8/6=AD/8
AD=8(8/6)=10.6666666667
Find AC using Pythagorus:
AC²=10.66666666667²+8²
AC=√177.7777777778
AC=13.333333333
4. √(40²+30²)=50
30/50=X/40
X=2.4
5. (√35)²=X²+5²
35=X²+25
X=√10
6. √((√10)²-(√6)²=√(10-6)=2
√6/2=X/√10
6/4=X²/10
X²=10(1.5)
X=√15

Challenge A large university accepts 40% of the students who apply. Of the students the university accepts, 35% actually enroll. If 20,000 students apply, how many actually enroll? students would actually enroll.
pls help I am so stuck on this.
Answer:
2800 students would actually enroll.
Step-by-step explanation:
Of the 20,000 students who apply to a university, 40% are accepted.
It means:
20,000 × 40% = 20,000 × 40/100 = 8000 students are accepted
Of these, 35% enroll.
8000 × 35% = 8000 × 35/100 = 2800 students enroll
Therefore, 2800 students would actually enroll.

What is the percent change from 80 to 20? I’m confused
Answer:
75% decrease
Step-by-step explanation:
To calculate the percentage increase:
First: work out the difference (increase) between the two numbers you are comparing.
Increase = New Number - Original Number
Then: divide the increase by the original number and multiply the answer by 100.
% increase = Increase ÷ Original Number × 100.
If your answer is a negative number, then this is a percentage decrease.
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing.
Decrease = Original Number - New Number
Then: divide the decrease by the original number and multiply the answer by 100.
% Decrease = Decrease ÷ Original Number × 100
If your answer is a negative number, then this is a percentage increase.

Answer:
Step-by-step explanation:
If Four goats and two sheep’s cost Rs.2500, while six goats and five sheep’s cost Rs.6000. Find
the cost of one goat and one sheep separately
Answer: Cost of one goat = Rs 62.50 and Cost of one sheep Rs 1125.
Step-by-step explanation:
Let x = Cost of one goat and y= Cost of one sheep.
As per given,
4x+2y= 2500 (i)
6x+5y= 6000 (ii)
Multiply (i) by 3 , we get
12x + 6y = 7500 (iii)
Multiply (ii) by 2 , we get
12 x + 10y = 12000 (iv)
Eliminate (iii) from (iv)
10y- 6y = 12000 - 7500
⇒ 4y = 4500
⇒ y = 1125
Put y =1125 in (i)
4x+2(1125)= 2500
⇒ 4x+2250= 2500
⇒ 4x =2500-2250
⇒ 4x =250
⇒ x= 62.50
Hence, Cost of one goat = Rs 62.50 and Cost of one sheep Rs 1125.

a street sign is 104 inches tall. How tall is it in feet and inches.
Answer:
8 ft 8 in
Step-by-step explanation:
104/12 = 8.666...
This shows that there are 8 total feet because there are 12 inches in a foot
Then, multiply 8*12 to get 96 in order to get the remainder of the inches left that do not make up one whole foot.
Then subtract 96 from 104 (104-96) to get the remainder which is 8 inches.

It takes me 20 minutes to do my math assignment for the day. I have been lazy and I spend 2 hours and 20 minutes doing my work last night. How many assignments did I finish?
Answer:
Assignments finished = 7
Step-by-step explanation:
Given that:
Time taken for one assignment = 20 minutes
Time spent on working = 2 hours 20 minutes
2 hours = 120 minutes
Time spent on working = 120 + 20 = 140 minutes
Number of assignments = [tex]\frac{Total\ time\ spent}{Time\ on\ one\ assignment}[/tex]
Number of assignments = [tex]\frac{140}{20}[/tex]
Number of assignments = 7
Hence,
Assignments finished = 7
Answer:
You finished seven (7) assignments.
Step-by-step explanation:
1. First, you need to know how many minutes are in an hour. That is 60 minutes.
2. If you know that it takes 20 minutes for each assignment and you spend 2 hours and 20 minutes to do all the assignments, you need to get both times to the same unit, minutes.
3. 2 hours is equal to 120 minutes. Now we need to add the other extra 20 minutes, leaving a total of 140 minutes of homework assignments.
4. Now you need to divide 140 minutes by 20 minutes because that is how long one assignment takes. 140÷20=7.
5. In the end, you finished 7 assignments in 2 hours and 20 minutes.

When multiplying a decimal by a power of 10, the product
Answer:
When a decimal number is multiplied by a power of ten, the product is found by moving the decimal point to the right that many places as the power of ten. For example, in 3.45 × 10 2, the product is obtained by moving the decimal point two places to the right, i.e., 3.452 × 10 2 = 345.2.
