Answer:
x = 6
Step-by-step explanation:
x/16 = 3/8
Step 1: Cross-multiply.
x/16 = 3/8
x*(8) = (3)*(16)
8x = 48
Step 2: Divide both sides by 8.
8x/8 = 48/8
*Ta da!*
x = 6

Answer:
D
Step-by-step explanation:
the other 3 options are all true.
the sum of all angles in a triangle is always 180°.
so, when T is 40°, that leaves 180-40 = 140° to the other 2 angles. in an isoceles triangle they must be equal to each other, so they are half of the remaining 140°, which is 70°.
and of course the 2 sides are equal (hence "isoceles").

And a recent year 28.1% of all registered doctors were females if there were 42,000 female registered doctors at your what was the total of registered doctors?
Answer:
Step-by-step explanation:
Discussion
This is a proportion question. A proportion is 2 ratios separated by an equal sign.
If you know three of the components you can solve for the fourth.
Givens
28.1 % are females
42000 are female doctors.
100% is what is required.
Equation
28.1% / 100% = 42000 / x Cross Multiply
28.1 * x = 42000 * 100 Combine
28.1 * x = 4200000 Divide by 28.1
28.1/28.1 x = 4200000/28.1
x = 149466 is the total doctors

what is the circumference and area of 17 diameter
Answer:
circumference: 17 x 2 = 34
Area: 3.14 x 8.5^2 = 226.865
Answer:
circumfrence: ≈53.40708 area:≈226.98007
Step-by-step explanation:
For area, the formula is A=πr^2, so first divide the diameter (17) by 2 to get the radius which is 8.5
square 8.5 and then multiply by pi
plug everything in to get ≈226.98007
For circumfrence the formula is πd, so multiply 17 by pi
plug everything in to get ≈53.40708
.. Discuss the nature of the root of equation x2 + 2x + 3 = 0
Answer:
No real rootsStep-by-step explanation:
Given equation:
x² + 2x + 3 = 0On comparing the equation by ax² + bx + x = 0, We get: a = 1, b = 2 and c = 3
To Find the nature of the roots of the equation firstly we need to find the discriminant of the equation. The expression b²- 4ac is called the discriminant.

Answer:
The area of room is 812 square feet, cost of carpet to cover the room is $6739.6 and the remaining square feet of carpet are covered by furniture is 203 square feet.
What is the area of trapezoid?The area of the trapezoid is the space occupied by it on the two dimensional plane. The area of this figure is half of the product of height and sum of sides.
[tex]A=\dfrac{(a+b)h}{2}[/tex]
Here, (a and b) are the base sides of the trapezoid and (h) is the height.
A room is shaped like a trapezoid which has the height of 28 feet and the length of sides as 23 ft and 35 ft. Thus, the area of it is,
[tex]A=\dfrac{(a+b)h}{2}\\A=\dfrac{(23+35)28}{2}\\A=812\rm\; ft^2[/tex]
Carpet costs $8.30 per square foot. Thus, the cost of carpet with area 812 ft² is,
C=812×$8.30
C=$6739.6
Furniture covers 25% of the floor. Thus, the remaining square feet of carpet are covered by furniture is,
[tex]A=\dfrac{25}{100}\times812\\A=203\rm\; ft^2[/tex]
Thus, the area of room is 812 square feet, cost of carpet to cover the room is $6739.6 and the remaining square feet of carpet are covered by furniture is 203 square feet.

Serika has hired Tom to build her a dollhouse. The dollhouse will be a scale model of her home, and the scale will be 2 inches :
3 feet.
The living room in Serika’s house is 18 feet by 12 feet and has wall-to-wall beige carpeting. How many square inches of
carpeting will Tom need for the living room in Serika’s dollhouse?
Answer:
96 square inches
Step-by-step explanation:
The scale is 2 inches : 3 feet
Thus for 18 feet in Serika's real house, the model is 18 * (2"/3') = 12 inches
For 12 feet in Serika's real house, the model is 12 * (2"/3') = 8 inches
Area of carpeting needed in Serika's dollhouse = 12" * 8" = 96 square inches
Jamal works at a sporting goods store on the weekends. Suppose last weekend he worked
12.5 hours and earned $110. How much money does Jamal earn per hour?
* Write an equation you can use to solve the problem , then find the solution
Answer:
$8.8 per hour
Step-by-step explanation:
Well, the equation is simple.
Time (hours) * Money (per hour) = Total
We know the time he worked for and the total amount he earned, so just replace in this equation and find the unknown number
12.5 * money = 110
To find the money he earns per hour we should just simply divide the total amount he earned by the hours he spent working
money = 110/12.5
money = 8.8$
You can also check it out to make sure it's correct.
If he earns 8.8$ per hour and worked for 12.5 hours how much he'll earn? Let's find out
8.8 * 12.5 =?
8.8 * 12.5 = 110, the same total amount so our solution must be correct.

D. 247
Applying the angle of intersecting secants and tangents theorem, m(KNL) is: A. 264°.
What is the Angle of Intersecting Secants and Tangents Theorem?The angle of intersecting secants and tangents theorem states that the angle formed outside a circle has a measure that equals 1/2 the positive difference of the measures of the intercepted arcs.
60 = 1/2(18x - 6 - 5x - 17) [angle of intersecting secants and tangents theorem]
Solve for x
2(60) = 13x - 23
120 = 13x - 23
120 + 23 = 13x
143 = 13x
x = 143/13
x = 11
m(KNL) = (18x - 6 + 5x + 17)
m(KNL) = 23x + 11
Plug in the value of x
m(KNL) = 23(11) + 11
m(KNL) = 264° (option A)
