Sarah applies the pearl guitar fret markers to her fret board as shown. Each fret marker is in the shape of a parallelogram. Each of the three bottom fret markers has a base that measures 52.5mm and a height of 6mm. What is the area of each of the bottom fret markers? DO NOT INCLUDE UNITS. *
Answer:
Step-by-step explanation:
Since each fret marker is in the shape of a parallelogram, we would determine the area of each of the bottom fret markers by applying the formula for determining the area of a parallelogram. It us expressed as
Area = base × height
Each of the three bottom fret markers has a base that measures 52.5mm and a height of 6mm. Therefore, area of each the bottom fret markers is
52.5 × 6 = 315
el volumen de un cubo es de 125 cm3 ¿ cuantas veses aumentara el volumen de ese cubo si se duplica la medida de su arista
Answer: 8 times.
Step-by-step explanation:
I will answer in English:
This says:
The volume of a cube is 125cm^3
How many times the volume will increase if we duplicate the lenght of the side?
If L is the lenght of the side, we have that the volume of the cube is:
V = L^3
If we duplicate the lenght of the side, the new volume is:
V = (2*L)^3 = 8*L^3
So we can see that the volume of the new cube is 8 times the volume of the previous cube.
Now, we can do the math, for our original cube we have:
L^3 = 125cm^3
L = 5cm
the new cube has L' = 2*L = 10cm
The volume of this cube is:
V' = L'^3 = 10cm^3 = 1000cm^3
the ratio V'/V is:
1000cm^3/125cm^3 = 8
the answer to the question
Answer:
All of the choices.
Step-by-step explanation:
A rational number is one that can be represented by the ratio of two integers. In other words, if you can write the number as a fraction of two whole numbers, then it is a rational number.
All of these numbers can be written this way. Therefore, all of the numbers seen are rational.

a square blanket has an area of 64 square feet. find the length of one side of the blanket
Answer:
The length of one side of the blanket is [tex]8ft[/tex]
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, a square shape.In this problem we are expected to find the side of the square shape.
we know that the area of the square is expressed as
[tex]area= length * width[/tex]
but a square shape has all sides equal hence
[tex]area= length* length\\[/tex]
[tex]area= l^{2}[/tex]
substituting our area and squaring both side to find l we have
[tex]64= l^{2} \\l= \sqrt{64} \\l= 8 ft[/tex]
A sphere is inscribed in a cube with a volume of 64 cubic inches. What is the volume of the sphere? Round your answer to the nearest whole number.
Answer:
the volume of the sphere is
[tex]33.51 in^{3}[/tex]
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere and cube.
Given data
Volume of cube v = 64 cubic inches
since we are dealing with a cube the height and the radius of the sphere is same as the sides of the cube,
we know that volume of cube is expressed as
[tex]v= l*b*h[/tex]
[tex]v=l^{3}[/tex]
[tex]64= l^{3}[/tex]
[tex]l= \sqrt[3]{64}[/tex]
[tex]l= 4 in[/tex]
also diameter d=length l
Diameter d= [tex]4in[/tex]
Radius r = [tex]\frac{d}{2}[/tex]= [tex]\frac{4}{2}[/tex]= [tex]{2 in}[/tex]
Height h=[tex]4in[/tex]
we know that the volume of a sphere is given by
[tex]v= \frac{4}{3} \pi r^{3}[/tex]
substituting into the formula we have
[tex]v= \frac{4}{3} \ *3.142*2^{3} \\v=\frac{4*3.142*8}3} \\v= \frac{100.54}{3} \\v= 33.52in^{3}[/tex]

Answer:
if you multiply by powers of 10 then make the decimal point go right.
Answer:
1.23 * 10^-7
Step-by-step explanation:
For decimals smaller than 1 usually something like 0.0000111 you count the decimal places backwards until you get to something greater than 0. So if you have 0.0022 the exponent would be 2.2 * 10^-3
For your problem 0.000000123
There's 6 zeros before you encounter the number thus your exponent is 1.23 * 10^-7

Step-by-step explanation:
Claire Reagan and Anthony deliver newspapers in the neighborhoods clear deliver 79 papers a day Reagan delivers 2490 papers a month Anthony delivers 616 papers a week how many do they deliver together in a year
Answer:
90,747
Step-by-step explanation:
Clair delivery=79 per day
Total delivery per year=79×365 days
=28,835
Reagan delivery=2490 per month
Total delivery per year=2490×12 months
=29,880
Anthony delivery= 616 per week
Total delivery per year =616×52 weeks
=32,032
Total delivery altogether in a year=28,835+29,880+32,032
=90,747
Answer:
Step-by-step explanation:
Clair delivers 79 papers a day.
Assuming that there are 365 days in a year, it means that the number of newspapers that Clair delivers in a year is
79 × 365 = 28835
Reagan delivers 2490 papers a month. There are 12 months in a year. it means that the number of newspapers that Reagan delivers in a year is
12 × 2490 =29880
Anthony delivers 616 papers a week. Assuming that there are 52 weeks in a year, it means that the number of newspapers that Anthony delivers in a year is
52 × 616 = 32032
Therefore, the number of newspapers that they deliver altogether in a year is
28835 + 29880 + 32032 = 90747
Asked 4 times, please help
Answer:
Denote the two points are A and B, the balloon is C. Then we have,
Side AB = 9 miles
Angle CAB (angle A) = 27 deg
Ange CBA (angle B) = 45 deg
=> Angle ACB (angle C) = 180 - 27 - 45 = 108 deg
Applying the sine theorem:
AB/sinC = BC/sinA
=> BC = AB x sinA/sinC = 9 x sin27/sin108 = 4.3 miles
Denote CH as the height from C to side AB (or distance from ground to balloon), we have:
CH = BC x sin B = 4.3 x sin*45 = ~3.04 miles
=> Distance from ground to balloon: ~3.04 miles
Hope this helps!
:)
Answer:
3.0 miles
Step-by-step explanation:
Let h be the height
Tan(27) = h/b
h = btan(27)
Tan(45) = h/(9-b)
(9-b)tan(45) = h
(9-b)tan(45) = btan(27)
9tan(45) = b[tan(45) + tan(27)]
b = 5.962138633
h = btan(27) = 3.037861367
Bob Tina and Hadley went running. Bob ran for 3/8 hour, Tina ran for 3 4/9 hours, and Hadley ran for 4 19/29 hours. Which running times can be written as improper fractions
Answer: 3 4/9 and 4 19/29
Step-by-step explanation: Mixed fractions can be converted into improper fractions. Example: 3 1/2=
3×2+1= 7/2
So, 3 4/9= 3×9+4= 31/9
4 19/29= 4×29+19= 135/29

(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)(^o^)
An improper fraction is one in which the numerator is bigger than the denominator, which means the value of the fraction is more than ' 1 ' .
Bob petered out after only 3/8 of an hour. This number is less than ' 1 ', so if it's left in the form of hours, it can't be an improper fraction. If Bob wants his effort to look more impressive, he might try to describe his performance as 22.5 minutes. THAT number could be written as an improper fraction, (45/2 minutes), but somebody would be sure to notice his trick, and they would laugh at him.
Tina and Hadley both ran longer than 1 hour, so both of them could write their times directly as improper fractions, without any deceptive monkey business.
Tina . . . 3-4/9 hours . . . 31/9 hours
Hadley . . . 4-19/29 hours . . . 135/29 hours
Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A: (2, -6) B: (5, -6) C: (5, -2) D: (2, -2). What is the perimeter of ABCD.
Answer:
14
Step-by-step explanation:
Graph all the points on a coordinate grid. Two sides are 4 units each and the other two sides are 3 unites each.
P = 2(l + w)
P = 2(3 + 4)
P = 6 + 8 ← (The distributive property) OR 2(7) ← (Normal way to solve)
P = 14 units and 14 units.
You could also do addition.
P = 3 + 3 + 4 + 4
P = 6 + 8
P = 14 units

At a sale, dresses were sold for $90 each. This price was 75% of a
dress's original price. How much did a dress originally cost?
Answer:
A dress originally costs $120
Step-by-step explanation:
To find the original cost of the dress, we will follow the steps below;
let x represent the original cost of the dress
75% of x = $90
[tex]\frac{75}{100}[/tex] × x = $90
[tex]\frac{75X}{100}[/tex] = $90
MULTIPLY both-side of the equation by 100
[tex]\frac{75X}{100}[/tex] × 100 = $90×100
At the right-hand side of the equation, 100 will cancel out 100, leaving us with just 75x
75x = $9000
DIVIDE both-side of the equation by 75
75x/75 = $9000/75
At the left-hand side of the equation 75 will cancel-out 75 leaving us with just x
x= $9000/75
x = $120
A dress originally costs $120
