Answer:
12
Step-by-step explanation:
Seema’s little sister is 2 years more than ¼ of Seema’s age, so you should subtract 2 from 5 to find ¼ of Seema’s age. If 3 is ¼ of Seema’s age, all you do is multiply it by 4 to get the original number. 3x4 is 12, so the final answer is that Seema is 12.

2 words per minutes
2 x 2 = 4
You can type 4 words in two minutes
Step-by-step explanation:
So if you can type 36 word in 18 minutes then divide 36 by 18 to get 2 words per minute. Now multiply 2 words by 2 minutes to get 4 words per minute, your answer.
Suppose I have a right trapezoid with base lengths of 4 and 16. Is there any way I can find out what the missing side is? (see image attached)
Answer:
no
Step-by-step explanation:
If you draw a line from the right end of the top base to the bottom base, parallel to the left side, you cut off a right triangle that has a bottom leg of 12 and two unknown sides (height, and slant length).
All you can say is that the unknown slant length is more than 12 units.
If you know the height, you can find the slant length (hypotenuse) using the Pythagorean theorem.
5 people are evenly sharing 12 kilograms of apples how many kilograms of apples should each person get
Answer:
2.4 kilograms
Step-by-step explanation:
Given: 5 people are evenly sharing 12 kilograms of apples
To find: quantity of apples that each person should get
Solution:
Use the unitary method to get the required answer.
Under unitary method, if the value of multiple items is given to us, divide the total value by the number of items to obtain the value of one item.
Quantity of apples for 5 people = 12 kilograms
Quantity of apples for 1 person = [tex]\frac{12}{5} =2.4[/tex] kilograms
So, each person should get 2.4 kilograms of apples.
Answer:
12/5 or 2 2/5
Step-by-step explanation:
We need to divide the 12 kilograms of apples by the 5 people sharing them, or 125
12 ÷ 5 = 12/5
12/5 = 5/5 + 5/5 + 2/5
= 1 + 1 + 2/5
= 2 2/5
Each person should get 12/5, or 2 2/5, kilograms of apple

Step-by-step explanation:
Each roll has 6 possible outcomes, so two rolls have 36 possible sums. We can make a table showing what these sums are:
[tex]\left[\begin{array}{ccccccc}&\textbf{1}&\textbf{2}&\textbf{3}&\textbf{4}&\textbf{5}&\textbf{6}\\\textbf{1}&2&3&4&5&6&7\\\textbf{2}&3&4&5&6&7&8\\\textbf{3}&4&5&6&7&8&9\\\textbf{4}&5&6&7&8&9&10\\\textbf{5}&6&7&8&9&10&11\\\textbf{6}&7&8&9&10&11&12\end{array}\right][/tex]
Of the 36 sums, 10 are greater than 8, and 18 are odd.
P(A) = 10/36 = 5/18
P(B) = 18/36 = 1/2
In a baseball tournament, teams get 5 points for a win, 3 points for a tie and 1 point for a loss Nathan’s team has 29 points how many different combinations of wins ties and losses can Nathan’s team have
Answer:
37 different combinations
Step-by-step explanation:
First of all, we will count the possible combinations that add up to 29.
-Losses only;
One possibility: 29 losses
-Ties & losses;
Nine possibilities: 1 tie and 26 losses; 2 ties and 23 losses; 3 ties and 20 losses;4 ties and 17 losses; 5 ties and 14 losses; 6 ties and 11 losses; 7 ties and 8 losses; 8 ties and 5 losses; 9 ties and 2 losses
-Wins & losses
Five possibilities: 1 win and 24 losses; 2 wins and 19 losses; 3 wins and 14 losses; 4 wins and 9 losses; 5 wins and 4 losses
Now, what we want to find from the question is number of possibilities for wins, ties, and losses all together. So, we will count up the ties and losses in the remainder for each case of a given number of wins.
Thus;
For 0 Wins: 0 ties and 29 losses; 1 tie and 26 losses; 2 ties and 23 losses; 3 ties and 20 losses;4 ties and 17 losses; 5 ties and 14 losses; 6 ties and 11 losses; 7 ties and 8 losses; 8 ties and 5 losses; 9 ties and 2 losses.
Which sums up to 10 possibilities
For 1 win; 0 ties and 24 losses; 1 tie and 21 losses........8 ties and 0 losses.
Which sums up to 9 possibilities
For 2 wins; 0 ties and 19 losses; 1 tie & 16 losses............ 6 ties and 1 loss.
Which sums up to 7 possibilities
For 3 wins; 0 ties and 14 losses; 1 tie and 11 losses ....... 4 ties and 2 losses.
Which sums up to 5 possibilities
For 4 wins; 0 ties & 9 losses; 1 tie and 6 losses....... 3 ties and 0 losses
Which sums up to 4 possibilities
For 5 wins; 0 ties and 4 losses; 1 tie and 1 loss
Which sums up to 2 possibilities
Thus;
Total number of possibilities of combinations of wins, ties and losses = 10 + 9 + 7 + 5 + 4 + 2 = 37

Answer:4x+15
Step-by-step explanation: PEMDAS. First you multiply 12x3 and 9x2 so you get 36-18. Then you subtract 18 from 36 leaving you with 18. Then you combine 18 and -3, leaving you with 4x-15.
Each person tries to balance his or her time between leisure and work. The tradeoff is that as you work less your income falls. Therefore each person has indifference curves which connect the number of hours of leisure, l, and income, s. If, for example, you are indifferent between 0 hours of leisure and an income of $1125 a week on the one hand, and 10 hours of leisure and an income of $750 a week on the other hand, then the points l = 0, s = 1125, and l = 10, s = 750 both lie on the same indifference curve.
The table below gives information on three indifference curves, I, II, and III.
Weekly Income Weekly Leisure Hours
I II III I II III
1125 1250 1375 0 20 40
750 875 1000 10 30 50
500 625 750 20 40 60
375 500 625 30 50 70
250 375 500 50 70 90
(a) On a sheet of paper, or using a calculator or other technology, graph the three indifference curves. (You will need these to answer part (d) of this problem.)(b) You have 95 hours a week available for work and leisure combined, and you earn $21.45/hour. Write an equation in terms of l and s which represents this constraint. (c) Graph this constraint with your graph of the indifference curves.(d) Estimate from the graph what combination of leisure hours and income you would choose under these circumstances. What is the corresponding number of hours per week you would work?

Answer:
∠HGB = 20°
∠ECD = 34°
∠GBH = 36°
∠FGH = 37°
Step-by-step explanation:
There are several useful rules regarding angles:
right angles are 90°the sum of angles in a triangle is 180°angles of a linear pair are supplementary (total 180°)vertical angles are congruentan exterior angle is equal to the sum of the remote interior anglesThis last observation is a consequence of the 2nd and 3rd observations.
__
angle ECD
Using the last observation, ∠ECD = 124° -90° = 34°.
angle HGB
Again, using the last observation, ∠HGB = 110° -90° = 20°.
angle GBH
There are at least a couple of ways to find this one. We assume that lines FB and EC are parallel, so angles HBC and ECD are corresponding, hence congruent. Angle GBC is the supplement of of 110°, so is 70°. Then ...
∠GBH = 70° -34° = 36°
angle FGH
Again, this angle can be found multiple ways. Here, we'll use the sum of angles in triangle FGB.
∠FGB +∠GBF +∠BFG = 180°
(∠FGH +∠HGB) +∠GBF +∠BFG = 180°
∠FGH +20° +36° +87° = 180°
∠FGH = 180° -143° = 37°
__
Least to greatest, the angles are ...
∠HGB = 20°
∠ECD = 34°
∠GBH = 36°
∠FGH = 37°

Noel read 90 minutes each day for 6 days. Tyra read minutes each day for 8 days. What is the difference, in minutes, between the total amount of time Noel read and the total amount of time Tyra read?
A) 30
B) 40
C) 60
D) 80
Help with this please
Answer:
C) 60
Step-by-step explanation:
For computing the difference between the time taken in minutes by Noel and Tyra first we have to compute individually which are as follows
For Noel, the time taken required
[tex]= Time\ required \times number\ of\ days[/tex]
[tex]= 90\ minutes \times 6\ days[/tex]
= 540 minutes
For Tyra, the time taken required
[tex]= Time\ required \times number\ of\ days[/tex]
[tex]= 60\ minutes \times 8\ days[/tex]
= 480 minutes
So the difference is
= 540 minutes - 480 minutes
= 60 minutes
Hence, the third option is correct

Answer:
y = x² - 8x + 17
Step-by-step explanation:
Recall this formula:
y = a(x-h)² + k
Original equation was y = x², which in this form looks like
y = 1(x - 0)² + 0
If the shape of the graph didn't change, that means that a (the compressor/intensifier) stayed the same (a - value) meaning we can write the equation as..
y = (x-h)² + k
Remember, (h, k) is the vertex, which looking from your graph is at (4, 1)
y = (x - 4)² + 1
y = x^2- 8x + 16+1
y = x² - 8x + 17
Complete the equation of the line whose slope is -2 and y-intercept is (0,-8).
y =
Answer:
y = -2x - 8
Step-by-step explanation:
The slope is the number in front of the x. If it is a whole number then the slope is number/1. Then the slope is rise over runs. Then the y-intercept is the number after the x. Sometimes there isn't y-intercept. In this one the y-intercept is -8.

Sphere with a diameter of 6 inches
Cylinder with a height of 6 inches and a diameter of 6 inches
Cone with a height of 6 inches and a radius of 3 inches
How are these three volumes related?
Answer:
They all have PI π in the formulas
Step-by-step explanation:
The volume of Sphere is, [tex]36\pi inch^3[/tex].
The volume of Cylinder is, [tex]36\pi inch^3[/tex].
The volume of Cone is,[tex]18\pi inch^3[/tex].
What is volume?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed mathematically using imperial or SI-derived units. Volume and the notion of length are connected.
First to find the volume of Sphere.
Given a diameter of sphere is 6 inches.
So, the radius is 6/2 = 3 inches.
Volume of Sphere is,
[tex]V = \frac{4}{3} \pi r^3\\V = \frac{4}{3} \pi (3^3)\\V = 36\pi inch^3[/tex]
Now, to find volume of Cylinder.
Given: Height = 6 inch, diameter = 6 inch so, radius = 3 inch
Volume of cylinder is,
[tex]V = \pi r^2h\\V = \pi (3^2)6\\V = 36\pi inch^3[/tex]
Now, to find the volume of Cone.
Given: Height = 6 inch, radius = 3 inch
Volume of cone is,
[tex]V = \frac{h}{3} \pi r^2\\V = \frac{6}{3} \pi (3^2)\\ V = 18 \pi inch^3[/tex]
Therefore, the above the volume of Sphere and Cylinder are equal.
And the volume of Cone is half of the volumes of Sphere and Cylinder.

when a number is decreased by 19% the result is 66 what is the original number to
the nearest tenth percent
Answer:
The original number is x = 66 .19
Step-by-step explanation:
Let 'x' be the number
Given data a number is decreased by 19% the result is 66
x - 19% = 66
x-0.19 = 66
Adding '0.19' on both sides , we get
x - 0.19 +0.19 = 66 +0.19
x = 66 .19
The original number is x = 66 .19
The original number is 66.19.
Given that,
The number is decreased by 19% the result is 66.
We have to determine,
What is the original number?
According to the question,
Let, the original number be x,
The number is decreased by 19% the result is 66.
[tex]x - \dfrac{19}{100} = 66\\\\x - 0.19 = 66\\\\x = 66 + 0.19\\\\x = 66.19[/tex]
Hence, The required original number is 66.19.
