Answer:
132= 14
Step-by-step explanation:
The ratio is the division of two quantities in fraction form thus the ratio of the number of boys to the number of adults is 13/2.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
As per the given data,
130 boys, 100, girls, and 20 adults.
The ratio of boys to adults = number of boys/number of adults
⇒ 130/20 = 13/2
Hence "The ratio is the division of two quantities in fraction form thus the ratio of the number of boys to the number of adults is 13/2".

Find the value of x that makes the quadrilateral a parallelogram
What is x?
To make it a parallelogram, the diagonals have to bisect each other (6x=3x+2)
Calculate and you will get x = 2/3
The value of x that makes the quadrilateral a parallelogram is 2/3.
What is a parallelogram?A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.
We have a quadrilateral.
To show that the quadrilateral is a parallelogram:
If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
That means,
6x = 3x + 2
3x = 2
x = 2/3
Therefore, the value of x is 2/3.

Jessie filled a cone-shaped birthday hat with candy. if the hat had a radius of 9cm and a height of 10cm what is the volume in cubic units of candy she filled the hat with? assume that pi =3.14 and round to the nearest tenth
Answer:
Volume of a cone = 847.8 cm³
Step-by-step explanation:
Volume of a cone = 1/3hπr²
π = 3.14
radius, r = 9 cm
height, h = 10 cm
Volume of a cone = 1/3hπr²
= 1/3 * 10 * 3.14 * 9²
= (1 * 10 * 3.14 * 81) / 3
= 2543.4 / 3
= 847.8
Volume of a cone = 847.8 cm³

Answer:
i got 7ft for the answer
Step-by-step explanation:
The length of the unknown side of the triangular frame is 7 ft.
What is a triangle?"A simple closed curve or a polygon formed by three line-segments (sides) is called a triangle."
From the drawn triangle
According to the law of cosines
[tex]x^{2} =3^{2} +5^{2} +2[/tex] × [tex]3[/tex] × [tex]5[/tex] × [tex]cos 120^{0}[/tex]
⇒ [tex]x^{2} =9+25+2[/tex] × [tex]3[/tex] × [tex]5[/tex] × [tex]\frac{1}{2}[/tex]
⇒ [tex]x^{2} = 9+25+15[/tex]
⇒ [tex]x^{2} = 49[/tex]
⇒ [tex]x = \sqrt{49}[/tex]
⇒ [tex]x = 7[/tex]

Examine the linear graph to find the slope , y-intercept, and write the equation for this linear relationship
Answer:
The slope of the line is: [tex]m=-\frac{1}{2}[/tex]
The y-intercept b = 3
The slope-intercept equation of the line is: [tex]y\:=\:-\frac{1}{3}x+3[/tex]
Step-by-step explanation:
Taking two points from the given graph
(0, 3) and (6, 0)
Determining the slope m
The slope between (0, 3) and (6, 0) using the formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between (x₁, y₁) and (x₂, y₂)
In our case,
(x₁, y₁) = (0, 3) (x₂, y₂) = (6, 0)now substitute (x₁, y₁) = (0, 3) and (x₂, y₂) = (6, 0) in the slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-3}{6-0}[/tex]
[tex]m=-\frac{3}{6}[/tex]
[tex]m=-\frac{1}{2}[/tex]
Thus, the slope of the line is: [tex]m=-\frac{1}{2}[/tex]
Determining the y-intercept (b)
The slope-intercept form of the line equation is given by
[tex]y = mx+b[/tex]
where
[tex]m[/tex] is the slope[tex]b[/tex] is the y-interceptFrom the graph, we can figure out the y-intercept by checking the value of y at x = 0.
If we closely check the graph, at x = 0, the value of y = 3
Therefore, the y-intercept b = 3
Slope-intercept Equation
We already know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
substituting b = 3 and m = -1/2
[tex]y\:=\:-\frac{1}{2}x+3[/tex]
Therefore, the slope-intercept equation of the line is: [tex]y\:=\:-\frac{1}{2}x+3[/tex]

Answer:
a) $215,892.50
c) $220,803.97
e) $222,534.58
f) $222.554.09
Step-by-step explanation:
The compound interest formula is ...
FV = P(1 +r/n)^(nt)
where principal P is invested at annual rate r for t years, compounded n times per year. In this problem, you have P=100,000, r=0.08, t=10, and the only variable of interest is n.
When calculations are repeated, it is often convenient to let a calculator or spreadsheet do them. You only need to program the formula once, then use it for the different values of the variable of interest. Most spreadsheets have this formula built in, so you don't even need to program it.
__
For continuous compounding, the formula is ...
FV = Pe^(rt)
FV = 100,000e^(0.08·10) = 222,554.09

△KJL~△WJX. Identify the coordinates of X and the scale factor.
PLZ help
Answer:
X(−64/3, 0); 8/3
Step-by-step explanation:
To find the coordinates of the point X, first find the scale factor for a dilation of two similar triangles in the coordinate plane
To determine the scale factor, set up a ratio of the lengths of two corresponding sides of the triangles.
Use the Distance Formula d=(x2−x1)2+(y2−y1)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√ to find the length of the sides JK and JW.
Point J is the origin. Thus, the coordinates of the point J are (0,0).
It is given in the figure that the coordinates of the point K are (0,6).
To find JK, substitute x1=0, x2=0, y1=0, and y2=6 into the distance formula.
JK=(0−0)2+(6−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√=62‾‾√=6
The length of JK is 6.
It is given in the figure that the coordinates of the point W are (0,16).
To find JW, substitute x1=0, x2=0, y1=0, and y2=16 into the distance formula.
JW=(0−0)2+(16−0)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√=162‾‾‾‾√=16
The length of JW is 16.
To determine the scale factor, set up a ratio of the lengths of two corresponding sides, JW and JK, of the triangles.
JWJK=166=83
The scale factor is 83.
To find the coordinates of the point X multiply the coordinates of the point L by the scale factor.
It is given in the figure that the coordinates of the point L are (−8,0).
X(−8⋅83,0⋅83)=X(−643,0)
The coordinates of the point X are (−643,0).
The figure shows the same triangles K J L and W J X as in the beginning of the task. Point X is at minus 64 thirds, zero.
Therefore, the coordinates of X is (−643,0) and the scale factor is 83.

Danny is building a pyramid modeled after one of the great pyramids of Giza in Egypt .The great pyramid has a height of 480 feet and a square base with each side measuring 755 feet if Danny builds the pyramid to one hundredths (1/100) the size what will the volume be for his pyramid
Answer:
91.204 cubic feet
Step-by-step explanation:
We are given that
Height of great pyramid, h=480feet
Side of square base, a=755 feet
Height of Danny's pyramid, h'=480/100 feet
Side of square base of Danny's pyramid, a'=755/100 feet
We have to find the volume of Danny's pyramid if the volume of Danny's pyramid is 1/100 the size of great pyramid.
We know that
Volume of square base pyramid, V=[tex]\frac{1}{3}a^2h[/tex]
Where a= Side of base
h=Height of pyramid
Using the formula
Volume of Danny's pyramid=[tex]\frac{1}{3}\times(755/100)^2(480/100)ft^3[/tex]
Volume of Danny's pyramid=91.204 cubic feet
10= 3(3) + b what is the slope and y-intercept
Answer:
slope: 3
y-intercept: 1
slope-intercept form equation: y = 3x + 1
Step-by-step explanation:
slope-intercept form is y = mx + b, where m = slope and b = y-intercept.
the equation you're given, 10 = 3(3) + b, is already in slope-intercept form and also already has the slope identified (it's 3!) so thankfully that's one less thing to solve for! :)
all you have to do now is solve for b.
first, multiply 3(3).
10 = 3(3) + b
10 = 9 + b
then subtract 9 from both sides of the equation. 9 and -9 cancel each other out, so the only thing you have to do for this step is subtract 9 from 10.
10 - 9 = b
1 = b aka b = 1
and now you have your b value!
so your slope is 3 and your y-intercept is 1.
i hope this helps! have a nice rest of your day <3

Answer:
765 mi867 mi459 mi408 mitotal: 2499 miStep-by-step explanation:
The estimated mileage is found by multiplying the map scale by the map distance:
#1: (204 mi/cm)(3.75 cm) = 765 mi
The last of your attachments correctly shows the mileage for each of the distances you have identified on the map.
(Please note that the map is actually showing Springfield, IL. The location of Chicago is at the south end of Lake Michigan, not in the middle of IL. Perhaps the grid incorrectly lists Chicago instead of Springfield.)

Of course, the total distance is the sum of the distances of the legs of the trip:
765 +867 +459 +408 = 2499 . . . . miles total distance
