Answer:
20.78
Step-by-step explanation:
sin a = perpendicular/ hypotenuse
where a is the base angle
here a = 60
sin 60 = 18/ x
since,
[tex] \sin(60) = \ \frac{ \sqrt{3} }{2}[/tex]
[tex] \frac{ \sqrt{3} }{2} = \frac{18}{x} [/tex]
√3 x = 36
x = 36/ √3
x = 36/ 1.732
x = 20.78

When she was born, Tabitha’s rich aunt put $10,000 in a bank account in Tabitha’s name to be saved for her college education. The account earns 6% annual interest.
Martin's family opened an account when he was born. They started by putting $15,000
in this account and then his family added $50 a month, which is $600 per year to his
account. The account did not earn interest over time.
a. Make a table showing the value of each account of each year for 5 years. Round
your answers to the nearest dollar. Explain what calculations you used to find

please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!
Answer:
Step-by-step explanation:
First, draw the diagram.
We have the variable, l.
Then, we have:
tan angle=opposite/adjacent
So plug it in, it will be:
tan 60=l/50m
So then l=tan60*50m.
tan60=1.732
l=1.732*50m
and so out answer ends up being 86.6m.
Note: I don't know if this is the best way but...that's how I did it.
y = 2x + 1 y = 3x - 1
Answer:
i think the answer is B
Step-by-step explanation:
5=6-1
5=5
just need to get the equations equal together then solve for x which will give u the x-coordinate of intersection then u need to put it in which equation u want to find the y-coordinate of intersection point :
2x + 1 = 3x - 1
Add both sides 1
2x + 1 + 1 = 3x - 1 + 1
2x + 2 = 3x
Subtract both sides 2x
2x - 2x + 2 = 3x - 2x
x = 2
( This is the x-coordinate of intersection point )
_________________________________
Now to find the y-coordinate of the intersection point we have to put the value of x we found in of the equations :
y = 2x + 1
y = 2(2) + 1
y = 4 + 1
y = 5
_________________________________
Thus :
intersection point = ( 2 , 5 )
So the correct answer is option B .
How many triangles can be drawn with one 90o angle, a 70° angle, and an included side measuring 3 inches? Explain. Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
Answer:
2
Step-by-step explanation:
This is because any of the sides can be the one measuring 3 inches. Since it is a triangle, the sum of angles is 180. Let the third angle be x.
So, x + 90° + 70° = 180°
x + 160° = 180°
x = 180° - 160°
x = 20°
So, the third angle is 20°.
If the included side is a side other than the hypotenuse side, we can find it by applying the sine rule.
The included side can be either side other than the hypotenuse.
Also, either of the third angle in each triangle can be 20°
So, we have two sides and two triangles.
If the included side is the hypotenuse side, we use Pythagoras' theorem to find the length of the other two sides (and they must be equal)since the angle between the two sides is a right-angle, that is, 90°.
Since the other two angles are not equal, we cannot have a triangle with two equal sides and an hypotenuse. That is, we cannot have an isosceles triangle. So, no third triangle.
So, the total number of triangles that can be drawn with one 90° angle, a 70° angle and an included side measuring 3 inches is 2.

Coordinates are (5,0) & (7,0)
Just refer to the point where the graph intersects the x-axis I think.
If the length of qr is 8 cm and the length of qs is 12 cm, what is the length of rs?
Answer:
8.94
Step-by-step explanation:
Given that
qs = 12cm
qr = 8cm
Required
rs
Using the pythagoras theorem
Let us assume qs is the hypotenuse side
qs² = qr² + rs²
12² = 8² + rs²
144 = 64 +rs²
rs² = 144 - 64
rs² = 80
rs = √80
rs = 8.94
Hence the value of rs is 8.94

Write an equation to fit the following situation. On Monday, 340 students
went on a trip to the zoo. All 7 buses were filled equally and 4 students had
to travel in cars.
use your equation from above to solve how many students were on each bus
will mark brainliest
Answer:
48
Step-by-step explanation:
first you need to subtract the total number of students 340, by 4:00 because four of them had to travel in cars so they weren't on the bus. since there are seven buses and now 336 students going to travel on buses each buses must be split equally so you need to divide 336 by 7 giving you 48
The current in a certain resistor is 0.50A when it is connected to a potential difference of 110V. If the operating potential is 130V, the current in the same resistor is
Answer:
0.59 A
Step-by-step explanation:
The current in a certain resistor is 0.50 A
The potential difference is 110v
The operating potential is 130v
The current in the same resistor can be calculated as follows
= 110/0.50
= 220
= 130/220
= 0.59
Hence the current is 0.59 A

because
6.3+7.2+2.8+4.9=21.2
then to find the 2 other sides you need to
7.2-4.9=2.3
and
6.3-2.8=3.5
I need a answer for this
Answer:
6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10^2
a^2 +64=100
a^2 = 100-64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6

The price of a house is originally listed at $150,000. The owners are having a hard time selling it and decide to reduce the price to $115,500. What is the percentage decrease of the price of the house?
Answer:
there is a 23% decrease in the price of the house
Step-by-step explanation:
percentage decrease of the price of the house = (price decrease of the house / initial price of the house) x 100
price decrease of the house =new price - initial price
$115,500 - $150,000 = $-34,500
( $-34,500 / $150,000) x 100 = -23%

Is this Distributive if it appears "backwards"?
Answer:
no it doesnt matter
Step-by-step explanation:
distributive property is correct
On selling an article for Rs 2300, a shopkeeper made a profit of 15 %. find the cost price of the article.
Let the cost price of article be x :
x + x × ( 15/100 ) = 2300
x + x × ( 5 × 3 / 5 × 20 ) = 2300
x + x × ( 3 / 20 ) = 2300
x + ( 3 × x / 20 ) = 2300
x + ( 3x / 20 ) = 2300
( 20x / 20 ) + ( 3x / 20 ) = 2300
20x + 3x / 20 = 2300
23x / 20 = 2300
Multiply both sides by 20
( 23x / 20 ) × 20 = 2300 × 20
23x = 2300 × 20
23x = 23 × 2000
Divide both sides 23
23x ÷ 23 = ( 23 × 2000 ) ÷ 23
x = Rs 2000
I NEED THIS ANSWER After simplifying, which expressions are equivalent? Select three options.
(3.4a – 1.7b) + (2.5a – 3.9b)
(2.5a + 1.6b) + (3.4a + 4b)
(–3.9b + a) + (–1.7b + 4.9a)
–0.4b + (6b – 5.9a)
5.9a – 5.6b
Answer:
1, 3, 5 are correct
Step-by-step explanation:
1. (3.4a – 1.7b) + (2.5a – 3.9b) = 5.9a - 5.6b
2. (2.5a + 1.6b) + (3.4a + 4b) = 5.9a + 5.6b
3. (–3.9b + a) + (–1.7b + 4.9a) = 5.9a - 5.6b
4. –0.4b + (6b – 5.9a) = 5.9b - 5.6a
5. 5.9a – 5.6b = 5.9a – 5.6b
