Drag numbers to show which one is closer to -1 and -1/4 on the number line
Answer:
-0.82 is closest to -1, and -0.28 is closest to -1/4
Step-by-step explanation:
you can start by converting all of them to a fraction or decimal:
-0.28 = -28/100 = -7/25 = -14/50
-0.82 = -82/100 = -41/50
-1/5 = -10/50
-4/5 = -40/50
-1 = -50/50
-1/4 = -12.5/50
the ratio of the measures of the angles in a triangle is 6:4:2, find each angle.
Answer:
let ratio 6:4:2 be 6x,4x and 2x
we have
6x+4x+2x=180 sum of interior angle of the triangle is 180
12x=180
x=180/12=15
Step-by-step explanation:
missing Angle are
6x=6×15=90°
4x=4×15=60°
2x=2×15=39°
does anyone wanna help a gal out with this 6th grade work due today
Answer:
2 - 30ft²
3 - 57yd²
Step-by-step explanation:
Hey There!
The first step in solving this problem is finding the formula for area of a trapezoid
[tex]A = \frac{a+b}{2} h[/tex]
a = base 1
b = base 2
h = height
For the first one the dimensions are
a = 6
b = 9
h = 4
now we just plug in the values
[tex]A=\frac{6+9}{2} 4\\6+9=15\\\frac{15}{2}=7.5\\7.5*4=30[/tex]
so the area of the first trapezoid is 30 ft²
For the second one the given dimensions are
a = 8
b = 11
h = 6
now we just plug in the values
[tex]A=\frac{8+11}{2} 6\\8+11=19\\\frac{19}{2} =9.5\\9.5*6=57[/tex]
so the area of the second trapezoid is 57 yd²

The diameter of a circle is 38 miles. What is the circle’s area?
Use 3.14 for pi
Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54

The data shows the speed, in miles per hour, of motorists on a stretch of
road.
42, 35, 44, 31, 47, 41, 36, 34, 39, 18, 37, 32, 37, 33, 43, 41, 44, 47, 46
18 miles per hour is an outlier.
0 47 miles per hour is an outlier.
The outlier decreases the mean speed.
The outlier decreases the median speed.
Answer:
18 miles per hour is an outlier
the outlier decreases the mean speed
Step-by-step explanation:
the low number of 18 is way different from the other numbers being in the 30's and 40's
this 18 will bring the mean of all the numbers own because it is a smaller number.
Answer:
Step-by-step explanation:
Mean:44
Median:31
Mode:47
determine whether the polygon is concave or convex?
Answer: Convex
Step-by-step explanation
The difference between convex and concave polygons lies in the measures of their angles. Another way to think of it is this: the diagonals of a convex polygon will all be in the interior of the polygon, whereas certain diagonals of a concave polygon will lie outside the polygon, on its exterior .Also If the interior angles of of the polygon are less than 180 degrees, then the polygon is convex. But if any one of the interior angles is more than 180 degrees, then the polygon is concave. T∴×∴T that was a lot
solve the quadratic y = −x^2 + 4x + 1 with steps plz!
Answer:
x = -0.24 or 3.73
Step-by-step explanation:
[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex] (There's supposed to be a ± between '-b' and the square root)
[tex]x^{2}[/tex] + 4x + 1 ( [tex]ax^{2} + bx + c[/tex] )
a = -1 ( there's no number before [tex]x^{2}[/tex] so its 1 )
b = 4
c = 1
Substitute into the quadratic equation.
[tex]\frac{-4 + \sqrt{4^{2} -4x1x-1 } }{2x-1}[/tex] ( the [tex]x[/tex] is just the multiplication sign )
= [tex]\frac{-4 + \sqrt{{16} +4 } }{-2}[/tex]
[tex]\frac{-4 + \sqrt{{20} } }{-2}[/tex] = -0.24 [OR] [tex]\frac{-4 - \sqrt{{20} } }{-2}[/tex] = 3.73
( The answers are to 2 decimal places )

In a high school orchestra, the ratio of cellos to violins is 1 to 3. There are 21 violins. Write and solve a proportion that gives the number c of cellos in the orchestra.
Answer:Number of cellos =7
Step-by-step explanation:
The ratio of cellos to violins is 1 to 3=1:3
Total ratio = 1+3=4
To find the total number of cellos and violins in the orchestrs,
Ratio of violins/ Total ratio x Total number of cellos and violins = Number of violins
3/4 x X= 21
X=21 x 4 / 3
X =7x 4 28.
Number of cellos =Ratio of cellos / Total ratio x Total number of cellos and violins
=1/4 x28
=7 cellos

Deepak sold his T.V set for ₹ 14100,losing 6%. For how much did he purchase it?
Answer:
₹14,946
Step-by-step explanation:
Tv s old for ₹14100

Answer: c
Step-by-step explanation:
Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.
