Answer:
4a[tex]\sqrt{x}[/tex]41
Step-by-step explanation:
12*2+9x2= Perimeter.
The perimeter P of rhombus is given as
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]
The diagonals of rhombus bisect each other at right angles and it has same perimeter as that of a square.
From this property stated above we can formulate side of rhombus is below in equation (1)
Side and diagonals of rhombus have following relation
[tex]\rm Let \; the \; side \; of\; rhombus = s\\Length\; of \; first \; diagonal = 8a\\ Length\; of \; second \; diagonal = 10a\\\\According \; to \; the \; identity\; for\; area \; of\; rhombus \\ s^2 = (p/2)^2 +(q/2)^2 ....(1) \\where \; p \; and\; q \; are\; the \; diagonals.[/tex]
so
[tex]\rm s^2 = (10a/2)^2 + (8a/2)^2\\s^2 = 25a^2 + 16a^2 = 41 a^2 \\s= \sqrt{41}a ......(2)[/tex]
Equation (2) represents side of rhombus
So the perimeter P of rhombus is given as
[tex]\rm P = 4\times s[/tex]
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]
The perimeter P of rhombus is given as
[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

In Eduardo's collection, the number of butterflies is 12 more than twice the number of moths. If there are x moths, choose the expression that represent the number of butterflies he has.
Answer:
y = 12 + 2x
Step-by-step explanation:
Given that :
Let number of butterflies = y
Number of moths = x
y = 12 more than twice the number of moths
y = 12 + 2x
Hence, the expression which relates the number of butterflies he has is :
y = 12 + 2x

Answer:
The answer is 4 m
Step-by-step explanation:
You have two values - the height and length and - and you are missing the width.
The volume (353 m^3) of this rectangular prism is equal to b(ase) x h(eight) x w(idth).
So we can create the equation: 352 = bhw = (8)(11)h = 88h
352/88 = 4
Therefore your missing value is 4.
Sam ran several errands and used 7 gallons of gas. There were 5 gallons left in the tank. (Use g as a variable.)

The formula for circumference is 2 * π * radius and in this case we want to use 3.14 for π and so we do 2 x 3.14 x 7 because the radius is half of the diameter (14) and once you do that you end up getting 43.96 and once you round you get 44ft so you are correct.

Four players from the NBA and their career 3-point percentage are listed below. 3-point percentage is calculated by dividing the number of 3-pointers the player makes by the number of 3-pointers he attempts. If Steph Curry attempted 25 3-pointers in his last game, how many can we assume he made?
Answer:
We can assume that the number of 3-pointers he made in his last game was 10 3-pointers
Step-by-step explanation:
In the question, we have;
The 3-point percentage rate for Stephen Curry = 43.5 successful made out of 100 attempts
The 3-point percentage rate for LeBron James = 34.5 successful made out of 100 attempts
The 3-point percentage rate for James Harden = 36.4 successful made out of 100 attempts
Whereby Steph Curry attempted 25 3-pointers in the last game he played and where 'x' represents the number of 3-pointers we can assume he made, we have;
x = 43.5% of 25
[tex]\therefore x = \dfrac{43.5}{100} \times 25 = 10.875[/tex]
Given that 'x' can only have whole number values, and the 3-point percentage is calculated using a larger number of attempts than 25, we can assume he made 10 3-pointers in his last game
The 3-pointers the Stephen Curry made in last game is 10, if he attempted 25 3-pointers.
It is given that the four players from the NBA and their career 3-point percentages are listed below in the table
It is required to find the number of 3 pointers he made if Steph Curry attempted 25 3-pointers in his last game.
What is percentage?It is defined as the ratio or number presented as fraction of 100, the symbol of percentage is %.
We have in the question that:
The 3-point percentage rate for Stephen Curry is 43.5% out of 100 attempts.
We know that,
[tex]\rm 3-point \ percentage = \frac{Number \ of \ 3-pointers}{Number \ of \ 3-pointers \ attempts} \\[/tex]
3 - point percentage for Stephen Curry = 43.5%
Number of 3-pointers he attempts = 25
Putting these values in the above formula, we get:
[tex]\rm 43.5 \%=\frac{Number \ of \ 3-pointers}{25} \\\\\rm \frac{43.5}{100} \times25 = Number \ of \ 3-pointers\\\\\rm Or \ number \ of \ 3-pointers = 10.875[/tex]
But the number of 3-pointers can be a whole number, so we can assume that the 3-pointers is 10.
Thus, the 3-pointers the Stephen Curry made in last game is 10, if he attempted 25 3-pointers.

What is the volume and total surface area?? PLEASE HELP
Step-by-step explanation:
the volume would be inside of the spear so i could be wrong but you would do 10 multiplied by 21 and you get 210. IF you did base and height the base would be 10ft and the height would be 21ft then you just do base times height and that gets you 210 . i could be wrong though

Figures 1 and 2 below show two polygonal regions used to approximate the area of the given shape. Find the average area, in square units, of the given shape using figures 1 and 2.
Answer:
figure 1 is 8.5 units^2 and figure 2 is 3 units^2 and the average are is 5.25 units^2
The overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Since the area is covered with either a square or a triangle. Therefore, we can write the area of this two as,
Area of a square = 1 unit × 1 unit = 1 unit²
Area of triangle = 0.5 × 1 unit × 1 unit = 0.5 units²
The overestimated area, the number of square and triangles are,
Number of square = 6
Number of triangle = 5
Total overestimated area = (6×1unit²) + (5×0.5unit²) = 8.5 unit²
The under estimated area, the number of square and triangles are,
Number of square = 2
Number of triangle = 2
Total Underestimated area = (2×1unit²) + (2×0.5unit²) = 3 unit²
Furthermore, the average area is,
Average area = (Total overestimated area - Total Underestimated area)/2
= (8.5 units² - 3 units²) / 2
= 5.5 units² / 2
= 2.75 units²
Hence, the overestimated area, the underestimated area, and the average area will be 8.5 units², 3 units², and 2.75 units², respectively.

Answer:
y = 6/7x - 37/7
Step-by-step explanation:
m = 6/7
(5, -1)
y - y1 = m(x - x1)
y + 1 = 6/7(x - 5)
y + 1 = 6/7x - 30/7
y = 6/7x - 37/7
Answer:
Step-by-step explanation:
Start by the point-slope form and given slope = 6/7 and point (5, -1)
(y-(-1)) / (x-5) = 6/7
7(y+1) = 6(x-5)
7y = 6x - 37
y = 6x/7 - 5 2/7

Answer:
[tex]x=\frac{3}{4}=0.75[/tex]
Step-by-step explanation:
From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.
In this case, we are given that two opposite sides have lengths of [tex]4x+5[/tex] and [tex]8[/tex]. Therefore, since the quantities must be equal, we can write the following equation to solve for [tex]x[/tex]: [tex]4x+5=8[/tex]. Solving for [tex]x[/tex], we get:
[tex]4x+5=8[/tex]
[tex]4x=3[/tex] (Use the Subtraction Property of Equality to subtract [tex]5[/tex] from both sides of the equation, which isolates [tex]x[/tex])
[tex]x=\frac{3}{4} =0.75[/tex] (Use the Division Property of Equality to divide both sides of the equation by [tex]4[/tex] to get rid of [tex]x[/tex]'s coefficient)
Hope this helps!
