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

Tell whether it is possible to draw a triangle with the given side lengths. 4 cm, 4 cm, 7 cm
Answer:
Given 3 sides are 4,4,7 cm. We know sum of 2 sides of triangle are greater than 3rd side. But given sides 4+4 doesn't equal 7. It's not possible to construct a triangle with the given lengths (4,4,7).
Step-by-step explanation:
U can only make a triangle with the same 3 length.
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

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.

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.

I thought of a number, multiplied it by 2 ½ , divided the result by 1 1/5 , subtracted 7/18 from it, and got 1 ⅚ . What was my number?
Answer:
1.06 or 1 1/15
Step-by-step explanation:
So, basically what we need to do is reverse the steps.
So now it goes like this:
We start with 1 5/6(1.83)
Then we add 7/18(0.389)
Then we multiply by 1 1/5(1.2)
Then finally, we divide by 2 1/2(2.5)
This will get us our answer. So:
1.83+0.389 = 2.219
2.219*1.2 = 2.6628
2.6628/2.5 = 1.06
This is 1.06 in decimal form, or 1 1/15 in fraction form
Hope this helps!
This can also be double checked, if you plug it into the orginal equation:
1.06, then you multiply by 2.5: 1.06*2.5= 2.6628
2.6628, then you divide by 1.2: 2.6628/1.2= 2.219
Then finally, 2.219 and subtract 7/18: 2.219-0.389= 1.83
So we have double checked, and our answer is still 1.06.
5.2182 rounded to the nearest thousandth

Find the area if the composite shape
Answer:
111 m²
Step-by-step explanation:
A rectangle is a quadrilateral (has four sides and four angle) with two pairs of parallel sides. Opposite sides of a rectangle are equal to each other. Also all the angles of a rectangle are 90° each.
The area of a rectangle = length * width
For rectangle 1, length = 12 m, width = 3 m
Therefore area of rectangle 1 = length * width = 12 m * 3 m = 36 m²
For rectangle 2, length =(12 m - 3 m - 3 m) = 6 m, width =(15 m - 10 m) =5 m
Therefore area of rectangle 2 = length * width = 6 m * 5 m = 30 m²
For rectangle 3, length = 15 m, width = 3 m
Therefore area of rectangle 3 = length * width = 15 m * 3 m = 45 m²
Area of composite shape = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3
Area of composite shape = 36 m² + 30 m² + 45 m² = 111 m²
The projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s2. A rocket is launched from the ground at an initial velocity of 39.2 meters per second. Which equation can be used to model the height of the rocket after t seconds? s(t) = –4.9t2 + 39.2 s(t) = –4.9t2 + 39.2t s(t) = –4.9t2 + 39.2t + 39.2 s(t) = –4.9t2 + 39.2t – 39.2
Answer:
s(t) = -4.9t² + 39.2t
Step-by-step explanation:
Given the projectile motion of an object can be modeled using s(t) = gt2 + v0t + s0, where g is the acceleration due to gravity, t is the time in seconds since launch, s(t) is the height after t seconds, v0 is the initial velocity, and s0 is the initial height. The acceleration due to gravity is –4.9 m/s²
Given
g = -4.9m/s²
v0 = 39.2m/s
s0 = 0m (the initial height)
On substituting into the formula;
s(t) = gt² + v0t + s0
s(t) = -4.9t² + 39.2t + 0
s(t) = -4.9t² + 39.2t
This gives the equation that models the height

Step-by-step explanation:
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%
