Answer:
12/5
Step-by-step explanation:
sqrt( x^2+49) = x+5
Square each side
(sqrt( x^2+49))^2 = (x+5)^2
x^2+49 = (x+5)(x+5)
Foil the right side
x^2+49 = x^2 +5x+5x+25
Combine like terms
x^2+49 = x^2 +10x +25
Subtract x^2 from each side
49 = 10x+25
Subtract 25 from each side
49 -25 = 10x
24 = 10x
Divide by 10
24/10 = 10x/10
12/5 =x
Check since we squared, we need to check for extraneous solutions
sqrt( (12/5)^2+49) = 12/5+5
sqrt(144/25 +1225/25) = 12/5+25/5
sqrt(1369/25) = 37/5

Heyo, could you help me? Thank you
Answer:
Step-by-step explanation:
This is one of those questions that has no answer. The first one is not a triangle. 3 and 6 = 9. Two of the legs have to longer than the third. 9 is not greater than 10.
So there is no answer. However leave a note of there is a mistake in what you wrote and I'll come back.
The other two are right (the middle one) and the last one is acute.

A total of h males and (h - 2) females visit the museum on a certain day. If total of visitors for that day is 80, what is the value of h? A. 38 С. 40 B. 39 D. 41
Given:
Number of males = h
Number of females = (h-2)
Total number of visitors = 80
To find:
The value of h.
Solution:
We have,
Number of males = h
Number of females = (h-2)
So, the total number of visitors is:
[tex]Total=h+(h-2)[/tex]
[tex]Total=2h-2[/tex]
It is given that the total number of visitors is 80. So,
[tex]2h-2=80[/tex]
[tex]2h=80+2[/tex]
[tex]2h=82[/tex]
Divide both sides by 2.
[tex]h=\dfrac{82}{2}[/tex]
[tex]h=41[/tex]
Therefore, the correct option is D.

The function f(x) = 830(1.2)x represents the number of students enrolled at a university x years after it was founded. Each year, the number of students is ____ the number the year before.
Answer:
1.2 times or 20%
Step-by-step explanation:
Given the function ; f(x) = 830(1.2)^x
This is an exponential function ;
Recall the general form of an exponential function ; f(x) = ab^x ;
Where a = Initial value ; b = growth rate
Hence, b = 1.2
Also, b = 1 + r
1.2 = 1 + r
r = 1.2 - 1
r = 0.2
r = 0.2 * 100% = 20%

Given g ( x ) = 3 x − 4 g(x)=3x−4, solve for x x when g ( x ) = 5 g(x)=5.
Answer:
g(5) = -19
Step-by-step explanation:
Substitute 5 for x in the equation
Plug in 5 for the x's and get g(x)=-3(5)-4 and then -15-4 which is -19 so g(x)=-19
Given sin A=-√3/2 and tan A >0, find cos A.
PLEASE HURRY AND SHOW WORK
Answer:
Below in bold.
Step-by-step explanation:
We have a right triangle here with the hypotenuse = 2 and the legs are 1 and √3.
If tan A > 0 then the opposite side to < A in the triangle is greater than the adjacent so the leg opposite angle A is √3 and the adjacent side = 1.
So cos A = adj/hyp = 1/2.

If a ring costs a jeweler $1500, at what price should it be sold to yield a profit of 50% on the selling price?
Answer:
$2250
Step-by-step explanation:
selling the ring at 100% of $1500 would equal 1500 and yield no profit
therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500
1.5 x 1500 = 2250

Answer:
Your answer would be the third one
Step-by-step explanation:
Triangle 1 - 73, 45
Triangle 2 - 47, 30
Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.
Option (4) is correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.
For any two triangles to be similar, it must have 2 angles which are having the same measure.
For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°
Only one angle is same, hence not similar.
Triangle 1: 103°, 32° and Triangle 2: 103°, 25°
Only one angle is same, hence not similar.
Triangle 1: 73°, 47° and Triangle 2: 47°, 30°
Only one angle is same, hence not similar.
Triangle 1: 105°, 23° and Triangle 2: 52°, 105
By using angle sum property in Triangle 1 the remaining angles is:
= 180 - (105 + 23) = 52°
By using angle sum property in Triangle 2 the remaining angles is:
= 180 - (52 + 105) = 23°
2 angles are same, hence similar.
Triangle 1: 99, 41° and Triangle 2: 40°, 99°
Only one angle is same, hence not similar.
Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

A retailer purchased an electric bicycle for Rs. 35000 and sold at a profit of 16% to a customer. How much did the customer pay for it with 13% VAT?
Please help
Answer:
Rs. 45,150
Step-by-step explanation:
Given data
Cost =Rs. 35000
Profit=16%
VAT=13%
Let us find the profit to be added
=16/100*35000
=0.16*35000
=Rs. 5,600
Let us find the VAT to be added
=13/100*35000
=0.13*35000
=Rs. 4,550
Hence the cost of the bike is
=4,550+ 5,600+ 35000
=Rs. 45,150

Dan rolls a fair dice and flips a fair coin what is the probability of obtaining an even number and a head
Half the numbers on the die are even so you have a 1/2 probability of getting an even number. There is also. 1/2 probability of getting heads on a coin flip.
To find the probability of both happening, multiply the probability of each together:
1/2 x 1/2 = 1/4
The probability of getting an even number and heads is 1/4
