Answer:
Width of the rectangle is 8 feet
Length of the rectangle is 13 feet
Step-by-step explanation:
Complete question -
The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 feet, what is its length?
Solution
Let the width of the rectangle be X feet
Length of the rectangle would be 2X -3 feet
Perimeter of the rectangle is 2 (length + breadth)
Substituting the given values, we get -
Perimeter = 2 (length + breadth)
[tex]42 = 2 [(2X-3) + X]\\42 = 4X - 6 + 2X\\48 = 6X\\X = 8[/tex]
Width of the rectangle is 8 feet
Length of the rectangle is [tex]2*8 -3 = 16-3 = 13[/tex] feet

If a number cube is rolled once, what is the probability of an even number facing upward?
Answer:
So the odds of rolling an even number are 3:(6−3)=1:1
Step-by-step explanation:
Sphere A has radius of 2 cm. Sphere B has radius of 4 cm. (=433 V = 4 3 π r 3 use 3.14 for π . ) a) The volume of sphere A is b) The volume of sphere b is c) The volume of Sphere B is_______times greater that the volume of Sphere A.
Answer:
volume of Sphere B is 8 times greater than the volume of Sphere A
Step-by-step explanation:
Sphere A: V = 4π (2^3)/3 = 32π/3
Sphere B: V = 4π (4^3)/3 = 4π(64)/3 = 256π/3
volume of Sphere B / volume of Sphere A = (256π/3)/(32π/3) = 8

9514 1404 393
Answer:
y = 7
Step-by-step explanation:
The slope is ...
m = (7 -7)/(0 -4) = 0
The y-intercept is the point (0, 7), so the slope-intercept equation is ...
y = mx +b
y = 0·x +7
Simplifying this puts it in standard form:
y = 7

Answer:
H = .298
Step-by-step explanation:
First lets plug in 1.5 for R and 16 for Surface area to get the following
2*pi*1.5^2+2*pi*h = 16 We are solving for H or height
Lets simplify this out a bit to get
16 = 14.13+6.28h
Subtract 14.13 from both sides
1.87 = 6.28h
h= .298
To check our answer lets plug the height into the equation
2*pi*1.5^2+2*pi*.298 = 16
Yes the height or H is .298
To check your answer just plug back what you got before into the equation
You love watching movies on your phone! Unfortunately each movie uses about
0.75GB. For this billing cycle, you’ve already used up 3 GB and your cellular plan
has a 15 GB data limit. How many movies can you watch without going over your
data limit?
1) Let M represent the number of movies you watch. Write an INEQUALITY to
model the number of movies that can be watched without going over the
data limit. Solve the inequality and show all of your work.
Answer:
[tex].75M+3<15[/tex]
[tex]M<16[/tex]
Step-by-step explanation:
This is a linear inequality so you would solve it as any normal linear system:
Subtract 3 from both sides to isolate the M term :
[tex].75M<12\\[/tex]
Divide each side by .75 to isolate M:
[tex]M<16[/tex]
That means you can watch less than 16 movies and stay under your 15GB limit.

Find x
In rectangle QRST, QS = 5x - 31 and RT = 2x + 11.
Find the lengths of the diagonals of QRST.
A.4
B.6
C.14
D.16
Answer:
C
Step-by-step explanation:
The diagonals of a rectangle are congruent, then
5x - 31 = 2x + 11 ( subtract 2x from both sides )
3x - 31 = 11 ( add 31 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39
The diagonals are each 39 units

find the size of x and y
this is a figure of parallelogram
Answer:
x = 75° , y = 105°
Step-by-step explanation:
Opposite angles in a parallelogram are equal , then
x = 75°
Consecutive angles in a parallelogram are supplementary, sum to 180° , so
x + y = 180° , that is
75° + y = 180° ( subtract 75° from both sides )
y = 105°

The constructions that are crucial to draw a circle inscribed on the given equilateral triangle are:
Construct line segmentsConstruct angle bisectors.How to make an inscribed circle in a triangle?There can be many different ways, one can include arc way, one can include angle bisector and perpendicular, and we can even try to discover some. But usually, (for the angle bisector and perpendiculars), we do the following:
Divide one of the angles in half.Divide another angle in half.The incenter, or point where they cross, is the inscribed circle's centre.Construct a perpendicular from the triangle's centre point to one of its sides.Draw an inscribed circle by placing the compass on the centre point and adjusting the length to where the perpendicular crosses the triangle.Drawing random arcs isn't gonna help mostly neither unspecific line segments. Drawing angle bisectors of the triangle and perpendiculars is one of the part.
