Answer:
when solving for multiplication
for instance
2*2=4
2+2=4
4+2=8
as 2*4,=8 after 4 you can add 2 to get the next multiple of 2
Same goes to the rest of other multiplication tables

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
Deepak sold his T.V set for ₹ 14100,losing 6%. For how much did he purchase it?
Answer:

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

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 )
The measure of H=90°, the measure of G=80° and FG=75 feet. Find the length of HF to the nearest tenth of a foot
Answer:
The length of HF is 73.9 feet.
Step-by-step explanation:
Let the length of HF be represented by x. So that applying the appropriate trigonometric function to the triangle FGH, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Where θ is the angle given in the triangle = [tex]80^{o}[/tex].
Then,
Sin 80 = [tex]\frac{x}{75}[/tex]
⇒ x = Sin 80 x 75
= 0.9848 x 75
= 73.86
x = 73.9
Thus, the length of HF is 73.9 feet.

5 Select the correct text in the passage. Which sentence best gets across the author's message in the story? A True Victory Kelso and his best friend, Adiel, had spent weeks building their go-cart for the annual Wolf Club go-cart race. Then, at the last minute, another team's go-cart broke down. Adiel and Kelso decided to let that team use their go-cart. But now they were regretting their decision. It was painful watching the race from the sidelines. When the first cart crossed the line, Adiel and Kelso couldn't helping wydering how it would have felt If they had won. Within seconds, other carts raced by. Instead of feeling glum, Kelso began to laugh. He delighted in the breeze that blew through his hair as the go-karts rushed past. Adiel noticed a genuine smile spread wide across Kelso's face. Adiel realized that this sense of happiness was also surging throughout his body, even though he had not raced. "You did a really nice thing today," whispered a nearby Wolf Club leader. "Thanks," said Adlel. "I guess I won't ever know if I could've won the race." "Well winning isn't one of the Wolf Club mottos," said the leader. "But we do believe that we should promise to do our best and do something good for somebody every day. I'd say you proved yourself today as one of the worthiest people here to be called a Wolf Cub." Adiel's mother soon appeared. "And I'm more proud of you now than I ever could have been if you had come in first," she said. Reset Next n. All rights reserved.

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

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.
