Fawzia has an action figure collection of 500 action figures. She keeps 58% of the action figures on her wall. How many action figures does she keep on her wall?
Answer:
290
Step-by-step explanation:
Formula :
Number of action figures on wall = Total number of figures × % of figures on wall
=============================================================
Given :
⇒ Total number of action figures = 500
⇒ % of action figures on wall = 58%
=============================================================
Solving :
⇒ Action figures on wall = 500 × 58%
⇒ Action figures on wall = 500 × 58/100 (all % are ratios of 100%)
⇒ Action figures on wall = 5 × 58
⇒ Action figures on wall = 290
Total action figures
58% of 5000.58(500)2.9(100)290action figuresDone!

Answer:
y = [tex]\frac{1}{2}[/tex] x
Step-by-step explanation:
the equation of a line passing through the origin is
y = mx ( m is the slope )

2y=-x+9
3x - 6y=-15
pls helpppp
Answer:
Step-by-step explanation:
The given equations are:
1) 2y = -x + 9
⇒ x = 9-2y
2) 3x - 6y = -15
⇒3x = 6y - 15
x = 2y - 5
Equating the values of x, we get:
9 - 2y = 2y - 5
9 + 5 = 4y
14 = 4y
y = 3.5
Using this value of y in equation 1 we get:
x = 9 - 2(3.5) = 2
So, the solution set is (2, 3.5)
If UW = 9x – 9, what is UW in units?
Answer
36 units
Step-by-step explanation:
UW = UV + VW
9x-9 = 2x - 4 + 4x + 10
9x - 9 = 6x + 6
3x = 15
x = 5
UW = 9(5) - 9 = 45 - 9 = 36
answer is 36 units

where;
k = scale factorFrom the given information:
The scale factor = 2the origin as a center of dilation for image vertices = (0, 0)Now, using the coordinate vertices:
A = (-1, -1)D = (2, -1)The corresponding coordinate of the image vertices is as follows:
A(-1,-1) → A'(2 × (-1), 2 × (-1))
A' = (-2,-2)
D(2,-1) → A'(2 × (2), 2 × (-1))
D' = (4,-2)

0.75x + 0.8x + 8 = 101

Write the equation 2x - 4y = 14 in slope-intercept form, and then find the slope and y-intercept.
Answer:
y = 1/2x - 7/2
Slope: 1/2
Y-intercept: (0, -7/2)
Step-by-step explanation:
We know the slope-intercept form of an equation of a line is y = mx + c where slope is m and y-intercept is c.
So, -4y = (-2)x + 14 [divide both sides by -4]
-4/-4 = -2/-4 + 14/-4
y = 1/2 -7/2
Hence the slope = 1/2 and y-intercept = -7/2.

Answer:
The answer is negative. Answer choice B
Step-by-step explanation:
Here is the question:
-3^40(5.6/2.1)
According to order of operations, we must do -3^40 first.
Its important to note that -3^40 is different than (-3)^40. In the problem you specified, the ^40 only applies to the 3, not -3. So, first we do 3^40 which is a huge number. And then, we need to add a negative symbol to that huge number. So now we have a massive negative number multiplied by 5.6/2.1, which is obviously positive. Obviously, a negative number multiplied by a positive number is still negative. Therfore, the answer is negative.
I hope my answer helped you :)

Carlita has a swimming pool in her backyard that is rectangular with a length of 24 feet and a width of 14 feet. She wants to install a concrete walkway of width c around the pool. Surrounding the walkway, she wants to have a wood deck that extends w feet on all sides. Find an expression for the perimeter of the wood deck.
The required, expression for the perimeter of the wood deck is 4w + 76 + 8c.
The length of the rectangular region will be the original length of the pool plus twice the width of the walkway since the walkway will extend out from both sides of the pool:
Length of rectangular region = 24 + 2c
Similarly, the width of the rectangular region will be the original width of the pool plus twice the width of the walkway:
Width of rectangular region = 14 + 2c
Now, to find the perimeter of the wood deck, we need to add up the lengths of all four sides of the rectangular region. Each side will have a length of w, since the wood deck extends w feet on all sides:
Perimeter of wood deck = 2(w + Length of rectangular region) + 2(w + Width of rectangular region)
Substituting the expressions we found for the length and width of the rectangular region, we get:
Perimeter of wood deck = 2(w + 24 + 2c) + 2(w + 14 + 2c)
= 4w + 76 + 8c
Therefore, the expression for the perimeter of the wood deck is 4w + 76 + 8c.

Ok for area for a triangle is 1/2 ×base×height and for a semi circle it is pi (π)or 3.14 or 22/7×rsquare with is radius x radius
Step-by-step explanation:
lets start with the triangle so it is 1/2×3/1×5/1×4/1 =30/1 =30sqkm
now for the semi circle it is 22/7×2/1×2/1=88/7=12.5÷2=6.2 why is 4/1 turned into 2/1 it is because you are finding area and 4 is the diameter but we need radius so the radius is half of the diameter
so 30+6.2=36.2kmsq

Find (fog)(0).
f(x)
=
6x
g(x) = 3x + 6
(fog)(0)
Answer:
12
Step-by-step explanation:
The functions f(x) and g(x) are defined as f(x) = 6x and g(x) = 3x + 6
fog(x) = f(g(x))
= f(3x + 6)
= 6(4x +2)
6 x 4x = 24x
6 x 2 = 12
fog(x) = 24x + 12
(fog)(0) where x = 0
= 24(0) + 12
= 0 + 12
(fog)(0) = 12
