Answer: x=10; y=-1
Step-by-step explanation:
To solve this via elimination:
get rid of the y's like this:
4x+2y=38 + 2x-2y=22
6x=60
x=10
20-2y=22
y=-1
In a survey of 292 students, about 9.9% have attended more than one play. Which
is closest to the number of students in the survey who have attended more than one
play?
3 students
10 students
20 students
30 students
Witch one
Answer:
30
Step-by-step explanation:
So we know that there are 292 people and 9.9% attended one play so you just find 10% of 300(approximated) which is the same thing as 30.

The key to this problem is to write out the probabilities and determine which one is most likely and least likely (or impossible).
Drawing a black card from a standard deck of playing cards:
There are 52 cards in a playing deck, 26 are red and 26 are black.
[tex]\frac{26}{52}[/tex] = [tex]\frac{1}{2}[/tex]
A spinner has 5 equal sections numbered 1 through 5. You spin and land on a number less than or equal to 4.
This means that all the numbers (1, 2, 3, and 4) except 5.
[tex]\frac{4}{5}[/tex]
You roll a standard number cube and get a number less than 2.
A standard cube is from 1 to 6, and 1 is the only number on the cube that is less than 2.
[tex]\frac{1}{6}[/tex]
You roll two standard number cubes and the sum is 1.
The smallest number on a standard cube is 1, so you can't make the sum 1 with 2 dice.
0
If we put these in order, we get:
[tex]\frac{4}{5}[/tex], [tex]\frac{1}{2}[/tex], [tex]\frac{1}{6}[/tex], 0
So, the order going from top to bottom in the picture is: 2, 1, 3, 4

A shopkeeper sells apples in two types of boxes, one small and one large. A large box
contains as many as 8 small boxes plus 4 loose apples. The number of apples in a
large box is given to be 100. Find the number of apples in a small box.
Answer:
12 apple in a small box.
Step-by-step explanation:
If there's 100 in a large box, then subtract the 4 loose apples to only have left 96 apples among the 8 small boxes. 96/8 is 12 apples per small box

Answer:
9.1 x 10² = 910
9.1 / 10² = 0.091
Step-by-step explanation:
Answer:
910 and 0.091
Step-by-step explanation:
multiply for 10^2 (100) means to move the comma to the right for two times
With a step we obtain 91. for the second step we have to add a zero and we have: 910
For the second the work is the same but with have to move the comma to the left two times,
first step: 0,91
second step : 0,091

A college professor teaching a class of Psychology gives the following grades during Fall semester: 15% A’s, 20% B’s, 40% C’s, and 10% D’s. The remainder of the students receive an F.
What is the probability that a randomly selected student does not earn an A in this class?
Answer:
85%
Step-by-step explanation:
Because we can see that only 15% of the class obtained A's, and the question only refers to those that did not receive A's, we can subtract the 15% of the 100% whole to get 85%. This can also be written as 85/100 or 17/20(simplified).

2. A right square pyramid is inverted so it is pointing down. The pyramid’s base has an area of 100 square centimeters and the area of one face is 60 square centimeters.
a. What is the volume of the pyramid?
b. The pyramid was filled with a solution. Some of the solution was drained out the vertex of the pyramid into a cylindrical dish with a radius of four centimeters. The level of liquid in the pyramid dropped three centimeters. How deep is the solution in the dish?
Answer:
2. a. The volume of the pyramid is approximately 363.62 cm³
b. The depth of the solution in the dish is approximately 0.15046 cm
Step-by-step explanation:
2. a. A right square pyramid is a pyramid with the vertex at the top directly above the center of the base
The area of the base of the right square pyramid = 100 cm²
The area of one of the face = 60 cm²
∴ The length of the side of the base, s = √(100 cm²) = 10 cm
The area of the face = 1/2 × s × l
Where;
l = The slant height
∴ 1/2 × 10 cm × l = 60 cm²
l = 60 cm²/(5 cm) = 12 cm
l = 12 cm
The height of the pyramid, h = √(l² - (s/2)²)
∴ h = √(12² - 5²) = √(119)
The volume of the pyramid = 1/3 × Base Area × Height
∴ The volume of the pyramid, V = 1/3 × 100 cm² × √(119) cm ≈ 363.62 cm³
The volume of the pyramid, V ≈ 363.62 cm³
b. The initial level of the solution in the pyramid = The pyramid was filled with the solution
∴ The initial level of the solution in the pyramid = The height of the pyramid
The radius of the cylindrical dish into which the solution is poured, r = 4 cm
The level by which the liquid drops in the pyramid after pouring = 3 cm
Therefore, by proportion of volume, we have;
Let V₁ and 'V' represent the volume that was drained out the vertex into the cylindrical dish and the volume of the whole pyramid respectively
Therefore;
V₁/V = (3/(√119))³
V₁ = V × (3/(√119))³
V = 1/3 × 100 cm² × √(119) cm
∴ V₁ = 1/3 × 100 cm² × √(119) cm × (3/(√119))³ = 100 cm² × 1 cm × 3²/(119) = 900/119 cm³
The volume that was drained out the vertex, V₁ = 900/119 cm³
The volume of the cylindrical dish, [tex]V_d[/tex] = π·r²·h
Where h = The depth of the solution in the dish
∴ When [tex]V_d[/tex] = V₁, and r = 4 cm, we have;
π × 4² × h = 900/119
h = (900/119)/(π × 4²) ≈ 0.15046
The depth of the solution in the dish, h ≈ 0.15046 cm.

Answer:
$12,155.06
Step-by-step explanation:
Using the compound interest formula;
A= P(1+r)^n
P = $10,000
rate r = 5% = 0.05
Time r = 4years
Substitute
A = 10,000(1+0.05)^4
A = 10,000(1.05)^4
A = 10,000(1.21550)
A = 12,155.06
Hence the amount after 4 years will be $12,155.06

10.507140429 nearest hundredth
Answer:
10.51
Always look to the right of the place you are rounding
so...
if you look at 10.507140429
the 0 after 5 is in the hundredths place
look to the right of 0 and you'll see a 7.
If the number to the right of the place you are supposed to round to is:
5 or greater - round up
less than 5 - round down

Alijah found 12 diamonds in a video game. Those 12 diamonds represented 48% of the total for the level he was on. How many total diamonds were on that level?
If Phoebe scored a 34 out of 42 on her recent math test, then what percent of the credit did she earn to the nearest percent?
Answer:
1. He earned 246
82% = 0.82
Move decimal right twice
82 x 300 is 24600
Move decimal left twice
= 246
2. 25
Solve for Y (Total Diamonds)
12 = 48% × Y
12 = [tex]\frac{48}{100}[/tex] × Y
Y = 12 × [tex]\frac{100}{48}[/tex]
Y = 12 × 100 ÷ 48
Y = 25

Answer:
Finding the product of 9, 10 and 9 ; 810
Step-by-step explanation:
Given that :
Length = 10 feets
Width = 9 feets
Height = 9 feets
The volume of a rectangular prism is obtained by :
Length * width * height
The volume could be obtained by taking the product of 10, 9 and 9
Hence, the volume of the rectangular prism is :
(10 * 9 * 9) feet³ = 810 feet³
Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810
