Answer:
9
Step-by-step explanation:
9² = 81
10² = 100
81 ... 90 ... 100
90 - 81 = 9
100 - 90 = 10
9 is less than 10
Hence, √90 is closer to 9
Oliver removed 56 marbles from his marble box and put them into 8 equal groups. How many marbles were in each group ? Please give the answer with statement, calculation and answer just like a word problem.
Answer:
Oliver had 56 marbles and he divided them equally in 8 groups. The number of marbles in each group = 56 marbles ÷ 8 groups = 7 marbles per group.
Step-by-step explanation:
In order to determine the number of marbles in each group you just have to divide the total number of units by the number of groups. In this case, the result is a whole number.

Each letter of the word "supercalifragilisticexpialidocious" is placed into a bag and drawn at 3 times, replacing the letter after each draw. Find the probability that the letter "i" is drawn at least once.
Answer:
P(X ≥ 1) = 0.50
Step-by-step explanation:
Given that:
The word "supercalifragilisticexpialidocious" has 34 letters in which 'i' appears 7 times in the word.
Then; the probability of success = 7/34 = 0.20588
Using Binomial distribution to determine the probability; we have:
[tex]P(X = x) = ^nC_x \ \beta^x \ (1 - \beta)^{n-x}[/tex]
where;
x = 0,1,2,...n and 0 < β < 1
and x represents the number of successes.
However; since the letter is drawn thrice; the probability that the letter "i" is drawn at least once can be computed as:
P(X ≥ 1) = 1 - P(X< 1)
P(X ≥ 1) = 1 - P(X =0)
[tex]P(X \ge 1) = 1 - \bigg [ {^3C__0} (0.21)^0 (1-0.21)^{3-0} \bigg][/tex]
[tex]P(X \ge 1) = 1 - \bigg [ 1 \times 1 (0.79)^{3} \bigg][/tex]
P(X ≥ 1) = 1 - 0.50
P(X ≥ 1) = 0.50

The area of the rectangle shown is at most 140 square centimeters.
a. Write and solve an inequality to find the possible
values of x.
10 cm
b. Based on the answer in part (a), is it possible for
the rectangle to have a length of 15 centimeters?
Explain.
(3x + 2) cm
9514 1404 393
Answer:
a) 10(3x+2) ≤ 140; x ≤ 4
b) no
Step-by-step explanation:
a) The area is the product of length and width. We want that product to be no greater than 140:
10(3x +2) ≤ 140 . . . . your inequality
We can solve this by dividing by 10 first.
3x +2 ≤ 14
3x ≤ 12 . . . . . . subtract 2
x ≤ 4 . . . . . . . . divide by 3; the solution to the inequality
__
b) If the length were 15, the area would be 10×15 = 150, which is greater than 140. The length cannot be 15 if the area is at most 140.

13 adults went to the movies
B)
1550/5=310
runner A ran four times as much as runner b
given the above, runner A ran 4*310 and B ran 310, since 1550/5=310
4*310=1240
The player with the most yards (runner A) ran 1240 yards

Answer:
Nu 4550
Step-by-step explanation:
Commission of 5% only applies to the first 70,000 so
[tex]70,000*\frac{5}{100} = 3500[/tex]
That leaves 15,000 left in sales where the 7% commission applies.
[tex]15,000*\frac{7}{100}=1050[/tex]
Adding these two together we get a total of

Solve the equation 4x-6= 34. Write a reason for each numbered step.
Answer:
Steps:
4x - 6 = 34
Add 6 to both sides
4x - 6 + 6 = 34 + 6
Simplify:
4x = 40
Divide both sides by 4
4x/4 = 40/4
Simplify:
x = 10

Is none proportional it proportional
Answer:No it is not proportional
Step-by-step explanation:
The reason non proportional is not proportional is bc it's not proportional.
Answer:
It's not proportional
Step-by-step explanation:
I can tell you that if you have, for example, 2 spring rolls and they are eaten by 4 people, then 1 spring roll is eaten by 2 people. That is proportional, becuase the amount of people is always dependened of the amount of spring rolls. But here, for 1 hour here, you get paid 52 dollars. If it was proportional, for 2 hours you'd be paid 104 dollars.

Maribelle uses x yards of material to make a quilt. A customer requests 5 quilts that are 20% larger than the normal pattern. Write an expression to represent the total yards of material needed for the requested quilts in two different ways?
Answer:
i. 5(x + 0.2x) yards
ii. 6x yards
Step-by-step explanation:
Since the requested quilts are 20% larger than the normal pattern, then;
20% of x = 0.2 x
Thus,the yards of material to make each of the requested quilts increased by 0.2x yards.
So that;
To make one of the requested quilt, the yards required = x + 0.2x
For 5 requested quilts, the total yards required = 5(x + 0.2x)
Total yards of material for the requested quilts is 5(x + 0.2x).
Also,
5(x + 0.2x) = 5x + 5(0.2x)
= 5x + x
= 6x
Thus, the total yards required is 5(x + 0.2x) or 6x.

What is the image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin?
Answer:
(-8, 9)
Step-by-step explanation:
A 180 degree rotation is:
[tex](x,y)\rightarrow(-x,-y)[/tex]
Apply the rule to the point given:
[tex](8,-9)\rightarrow\boxed{(-8,9)}[/tex]
Hope this helps.
The image of the point (8,-9) after a rotation of 180° counterclockwise
about the origin is (-8, 9).
How does rotation by 90 degrees changes coordinates of a point if rotation is with respect to origin?Let the point be having coordinates (x,y).
Case 1: If the point is in first quadrant:
Subcase: Clockwise rotation:
Then (x,y) → (y, -x)
Subcase: Counterclockwise rotation:
Then (x,y) → (-y, x)
For points on axes, You can take that point in any of the two surrounding quadrants. Example, if the point is on positive x axis, then it can taken as of first quadrant or fourth quadrant.
It is noted that for a 180 degree rotation the points move from (x, y) to (-x, -y)
A 180 degree rotation is:
(x, -y) --- (-x, y)
Apply the rule to the point given:
(8,-9) --- (-8, 9)
Hence, The image of the point (8,-9) after a rotation of 180° counterclockwise about the origin is (-8, 9).
