Rosalinda has a circular serving platter in the middle of her circular table.
The radius of the platter is 15 inches less than the radius of the table
The diameter of the table is 4 feet. What is the difference between the
area of the table and the area of the platter? Use 3.14 for 17, and write your
answer in decimal form. 7.G.4

576π-81π495π1554.3in²Answer:
1554.3 in²
Step-by-step explanation:
Given information:
The radius of the platter is 15 inches less than the radius of the tableThe diameter of the table is 4 feetπ = 3.141 foot = 12 inches
⇒ 4 ft = 4 × 12 = 48 in
Radius = ¹/₂ diameter
⇒ Radius of table = ¹/₂ × 48 in = 24 in
⇒ Radius of platter = 24 in - 15 in = 9 in
Area of a circle = πr²
⇒ Area of table = 3.14 × 24² = 1808.64 in²
⇒ Area of platter = 3.14 × 9² = 254.34 in²
Difference = area of table - area of platter
= 1808.64 - 254.34
= 1554.3 in²

O 723,2 cm
O 1868.2 cm
O 1436,0 cm
O 2052,5 cm
⠀
Explanation :
⠀
We know,
[tex]{ \longrightarrow{\qquad \pmb {\sf Volume_{(Sphere)} = \dfrac{4}{3} \pi {r}^{3} }}}[/tex]

The function f(x)=(2)(1.0)+x(0.5)2+x models the concentration of pineapple when 2 gallons of pineapple juice are added to x gallons of another juice. Find the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice. Give the answer as a percent but do not include the percent sign (%).
The concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice is 5.75
Functions and valuesGiven the functions that model the concentration of pineapple when 2 gallons of pineapple juice are added to x gallons of another juice as:
f(x)=(2)(1.0)+x(0.5)²+x
If the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice, then;
f(3) = (2)(1.0)+3(0.5)²+3
f(3) = 2.0 + 3.75
f(3) = 5.75
Hence the concentration of pineapple when 2 gallons of pineapple juice are added to 3 gallons of the other juice is 5.75

The perimeter of a triangle is 7 m. The longest side is twice the length of the shortest side. The sum of the
lengths of the shortest side and the middle side is 1 m more than the length of the longest side. Find the
lengths of the sides.
Answer:
See below in bold.
Step-by-step explanation:
Let the length of the shortest side be x, then the longest side = 2x.
Also x + y = 2x + 1 where y = length of the middle side,
Simplifying:
2x - x - y = -1
x - y = -1 (A)
Also as the perimeter = 7:
x + 2x + y = 7
3x + y = 7 (B)
Adding (A) and (B):
4x + 0 = 6
x = 6/4 = 1.5
Plug x = 1.5 into equation B:
3(1.5) + y = 7
y = 7 - 4.5 = 2.5.
Answer:
So the shortest side = 1.5, middle = 2.5 and longest = 2*1.5 = 3.

Mai and her sister are planting a garden.They made 2 plant beds.one was 4 feet by 3 feet and the other 5 feet by 5 feet.they want to outline the beds with bricks that are 1foot long.How many bricks will they need to outline both beds?
Answer:
27 bricks
Step-by-step explanation:
find the perimeter of the first one, 4 x 3 = 12. Then the perimeter of the second one, 5 x 5 = 25. Therefore 12 + 15 = 27. Meaning you need 27 bricks

GEOMETRY: VOLUME & SURFACE AREA!! HELP PLEASE WITH ANY ONE OF THEM!!
Answer:
1) 728
2) 274.89
Step-by-step explanation:
Find the volume and surface formulas for each shape attached.
I'll do a couple for you. For rest just use the formulas and input the values and solve.
1) It is a pyramid.
V = 1/3 * b * h, where b is the area of base, which is a rectangle so,
b = l * w
so,
V = 1/3 * l * w * h
V = 1/3 * 8 * 21 * 13
V = 1/3 * 2184
V = 2184 / 3
V = 728
2) It is a cylinder
[tex]V = \pi *r^2*h[/tex]
V = π * 5^2 * 3.5
V = π * 25 * 3.5
V = 87.5 π
V = 274.89

On a coordinate plane the graph of a line passes
through the origin and the point (9,12) What is
the equation of the line?
Answer:
y = (4/3)x
Step-by-step explanation:
Two points on the line are the origen (0, 0) and the given (9, 12).
Starting at the origin and moving to (9, 12), we see the change in x being 9 and that in y being 12. Thus, the slope of the line through these two points is m = rise/run = 12/9 = 4/3.
Thus the equation of the line in slope-intercept form is y = (4/3)x + 0, or
just y = (4/3)x

Answer:y=x^2 translated 3 to the right gives
y=(x-3)^2, the vertex shifts from (0,0) to (3,0)
translate it 4 up by adding 4
y=(x-3)^2 + 4, this shifts the vertex up to (3,4)
f(x) = (x-3)^2 + 4 or call it
g(x) = (x-3)^2 + 4 if you want to distinguish it from the original f(x) function
Step-by-step explanation:In this question we have been given a function f(x) = |x|
When we perform a translation of 4 units right then the translated form of the function becomes f(x) = |x - 4|
And when we we translate the function up by 2 units then the transformed form is f(x) = |x - 4| + 2
Therefore the given graph in option B is the correct option.

Find the measure of each angle in the isosceles trapezoid.
Answer:
Step-by-step explanation:
Find sin(2x), cos(2x), and tan(2x) from the given information.
sin(x) = [tex]-\frac{3}{5}[/tex] for [tex]\frac{3\pi }{2}[/tex] < x < 2
I assume 3π/2 < x < 2π, so that x is in the 4th quadrant. For angles x terminating in Q4, we have sin(x) < 0 and cos(x) > 0, so tan(x) = sin(x)/cos(x) < 0.
This means that, using the Pythagorean identity,
cos(x) = + √(1 - sin²(x)) = 4/5
tan(x) = (-3/5) / (4/5) = -3/4
Recall the double angle identities:
sin(2x) = 2 sin(x) cos(x) = 2 (-3/5) (4/5) = -24/25
cos(2x) = 2 cos²(x) - 1 = 2 (4/5)² - 1 = 7/25
tan(2x) = 2 tan(x) / (1 - tan²(x)) = 2 (-3/4) / (1 - (-3/4)²) = -24/7

What are the missing numbers for this ratio table
Answer:
y = 8x = 9Step-by-step explanation:
The ratios of the numbers shown in the table are all ...
y/x = 16/4 = 20/5 = 4
Then the missing y-value is ...
y = 4x
y = 4(2) = 8
__
And the missing x-value is ...
36 = 4x
36/4 = x = 9
_____
Additional comment
The x- and y-values in a "ratio table" are proportional to each other. That means the y corresponding to half an x-value will be half the y-value. In other words, the y for x=2 will be half the y for x=4, or 16/2 = 8.
Also, the values add. We notice that y=36 is the sum of y=16 and y=20. This means the corresponding x-value for y=36 will be the sum of x=4 and x=5, or x = 4+5 = 9.
