Using the rule y = 2x + 3, find the value of y when x is 3. A) 0 B) 8 C) 9 D) 12

1 answer:

7 0

Hi there.

Y = 2x + 3
Solve for y when x = 3
The first thing we need to do is replace x by the 3 in the equation.
Y = 2(3) + 3
Y = 6 + 3
Y = 9
Thus, your answer is : C

Answer: B. 84 in²

Step-by-step explanation:

Divide the area into two regions: a rectangle and a trapezoid (depicted in the attached photo).

Find the area of the rectangle:

Area of a rectangle=length*width

Area of rectangle=(5 in)( 10 in)

Area of rectangle=50 in²

Next, calculate the area of the trapezoid:

Area of trapezoid= $\frac{h(b_{1} +b_{2}) }{2}$

h=10 in-6 in

h=4 in

$b_{1} =15 in$

$b_{2} =15 in-5 in$

$b_{2} =10 in$

Area of trapezoid= $\frac{4in(7 in+10in)}{2}$

Area of trapezoid= $\frac{4(17in^{2}) }{2}$

Area of trapezoid= $\frac{68in^{2} }{2}$

Area of trapezoid= $34in^{2}$

Add the area of the trapezoid to the area of the rectangle to find the total area: 50 in²+34 in²=84 in²

A cone and its dimensions are shown in the diagram. What is the volume of the cone in cubic inches

aliya0001 [1]

Answer:1

V = 62.1262 cubic inches

Step-by-step explanation:

The formula for volume of a cone is V = (1/3)πr²h where r is the radius of the base, and h is the height.

We are given the height, h = 7 1/2 inches, or 15/2 inches

We are given the diameter of the base of 5 5/8 inches, or 45/8 inches

The radius is half the diameter, so divide 45/8 by 2. The radius is 45/16.

Plug these values into the formula and find V

V = (1/3)π(45/16)²(15/2)

V = 30,375π/1,536 = 62.12622191

rounding to 4 decimal places gives us 62.1262 cubic inches
