Answer:
42 square feet
Step-by-step explanation:
SA=2lw+2lh+2wh
SA=2*3*3+2*3*2+2*3*2
SA=2*9+2*6+2*6
SA=18+12+12
SA=30+12
SA=42
Thus,
Rashid needs 42 square feet of wood to build a box
Write an equation for the function that includes the points (3,12) and (4, 24)
10 points
fx=6/3 * 2^x
fx= 3/2 * 2^x
fx = 2x
Answer:
Equation for the function is:
f(x) = (3/2) · 2ˣ
Step-by-step explanation:
We have been provided with 2 points
Point 1 : (3, 12)
Point 2 : (4, 24)
Testing all three equations:
1) f(x) = 6/3 · 2ˣ
Substitute x of Point 1 in the equation
f(x) = (6/3) · 2³
f(x) = 16
y = 16 ≠ 12
NOT TRUE
Substitute x of Point 2 in the equation:
f(x) = (6/3) · 2⁴
f(x) = 32 ≠ 24
NOT TRUE
2) f(x) = 3/2· 2ˣ
Substitute x of Point 1 in the equation
f(x) = (3/2) · 2³
f(x) = 12
y = 12
TRUE
Substitute x of Point 2 in the equation:
f(x) = (3/2)· 2⁴
f(x) = 24
TRUE
3) f(x) = 2x
Substitute x of Point 1 in the equation
f(x) = 2(3)
f(x) = 6
y = 6 ≠ 12
NOT TRUE
Substitute x of Point 2 in the equation:
f(x) = 2(4)
f(x) = 8 ≠ 24
NOT TRUE

i wanna found all area firstly. thats why multiplaying 44 with 16.
44×16 = 704.
now ill find the triangle's area because ill remove it from the all area to find the shaded part of rectangle.
for triangle's area: 12×16/2 = 96.
now i substrack 704 from 96.
704-96= 608 square meters.

what is the value of x?
a. 80
b. 52.5
c. 75
d. 105
Answer:
x = 75
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary
x+ 105 = 180
Subtract 105 from each side
x+105-105 = 180-105
x = 75
Answer:

Step-by-step explanation:
0.16
The coordinates for point M is (12, 6)
what is section formula?Section formula is used to find the coordinates of a point that splits a line segment internally or externally into a ratio of m:n.
(x, y) = ( mx2 + nx1/ m+n, my2 + ny1/ m+n)
Given:
Coordinates of A(0, 15) and B (20, 0)
ratio is 3:2
Now,
x1=0, x2= 20, y1= 15, y2=0
let the coordinates of M is (c, d)
Using section formula
c=2*0+3*20/5
c=12
and d= 15*2+ 2*0/5
d= 6
Hence, the coordinates of M are (12, 6).

From a standard 52 deck of cards, find the probability that you draw a heart on the first
draw, replace it, and then draw a diamond on the second draw.
Leave your answer in decimal form to 4 decimal places.
Answer:
0.004
Step-by-step explanation:
Answer: 0.5
Step-by-step explanation:
There are 13 hearts. The chance of drawing a heart in your first draw is 13/52, or in other words 1/4
There are 13 diamonds. The chance of drawing a diamond on your second draw is 13/52, or in other words, 1/4
The chance of drawing a heart, replacing it, drawing a diamond, are 1/4*1/4=1/2.

1/2x+6= 16
Answer:
x = 20
Step-by-step explanation:
x in (-oo:+oo)
(1/2)*x+6 = 16 // - 16
(1/2)*x-16+6 = 0
1/2*x-10 = 0 // + 10
1/2*x = 10 // : 1/2
x = 10/1/2
x = 20
Three more than twice a number is greater than negative .fifteen. Solve the inequality for the unknown number.
Answer: n > -9
Step-by-step explanation:
3+2n > -15
2n> -18
n > -9
Write an inequality to represent the model and solve for the unknown number
let
the unknown number = x
twice a number = 2 × x
= 2x
Three more than twice a number = 2x + 3
Three more than twice a number is greater than negative fifteen:
2x + 3 > -15
2x > -15 - 3
2x > - 18
Divide both sides by 2
x > -18/2
x > -9
Therefore, the unknown number x, is greater than -9

Find the volume of this cylinder. Give your answer to one decimal place.
Answer:
1329.8 cm³
Step-by-step explanation:
Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]
We are given the height of 14 cm, and the diameter of 11 cm.
The radius is half the diameter.
[tex]11/2=5.5[/tex]
The radius is 5.5.
I use 3.14 for pi:
[tex]V=3.14*5.5^2*14\\\rightarrow 5.5^2=30.25\\V=3.14*30.25*14\\\boxed{V=1329.79}[/tex]
1329.79 ≈ 1329.8
The volume of the cylinder should be 1329.8 cm³.
What is the area of the squares with sides (2x-3)feet?
Answer:
4x^2 -12x +9 ft^2
Step-by-step explanation:
The area of a square is
A = s^2 where s is the side length
A = (2x-3) ^2
A = (2x-3) (2x-3)
FOIL
first 2x*2x =4x^2
outer 2x (-3) = -6x
inner -3*2x = -6x
last -3*-3 = 9
Add them together
4x^2 -6x-6x +9
Combine like terms
4x^2 -12x +9
The area is 4x^2 -12x +9 ft^2
Answer:
[tex]= 4 {x}^{2} - 12x + 9 {ft}^{2} \\ [/tex]
Step-by-step explanation:
[tex]area = {x}^{2} \\ = (2x - 3)^{2} \\ = (2x - 3)(2x - 3) \\ = 2x(2x - 3) - 3(2x - 3) \\ = 4 {x}^{2} - 6x - 6x + 9 \\ = 4 {x}^{2} - 12x + 9 {ft}^{2} [/tex]

Matthew has $1,500 in his savings account. Currently, he pays $20 each month for an
app that he has subscribed to and $30 each month at his favorite Italian restaurant. If
he does not spend money on anything else or make any other deposits into his savings
account, for how many months can he continue to make these purchases without going
into debt?
Answer: 30 months
Step-by-step explanation:
Hi, to answer this question we have to write an equation:
Matthew's saving account money (1500) must be equal to the product of the amount he pays per month for the app subscription (20) and the number of months (x); plus the product of the amount he pays per month for the Italian restaurant subscription (30) and the number of months (x).
1500= 20x+30x
Solving for x:
1500=50x
1500/50 =x
30 months =x

PLEASE HELP ASAP
Answer:
Tamara needs to cover a total of 476 square feet.Tamara will have enough material to cover all four walls.Step-by-step explanation:
If the room dimensions are 8 1/3 feet by 11 1/2 feet, the perimeter length is ...
P = 2(L+W) = 2(8 1/3 +11 1/2) = 2(19 5/6) = 39 2/3 feet
The area of the walls is the product of this perimeter length and the height of the wall. If that height is 12 feet, then the wall area is ...
A = PH = (39 2/3 ft)(12 ft) = 476 ft²
Tamara needs to cover a total of 476 square feet.
