Answer:
Flipping the coin:
P( H ) = 1/2
---------------------
Rolling the die:
There are 6 numbers
1,2,3,4,5,6
3 of them are odd, so
P( odd ) = 3/6
P( odd ) = 1/2
Step-by-step explanation:
There are 52 cards in a deck
There are +9%2A4+=+36+
cards less than +10+
P( <10 ) = 36/52
P( <10 ) = 9/13
-----------------
Since you want ALL the above,
multiply probabilities
+%281%2F2%29%2A%281%2F2%29%2A%289%2F13%29+=+9%2F52+

what is 8 & 3/4 x 3
(I need this today!)
3/4 x 3 = 9/4
Since you need to multiply first you add the 8 later after you solve the multiplication
8 9/4
Answer:
26 [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
8[tex]\frac{3}{4}[/tex] = [tex]\frac{(8x4)+3}{4}[/tex] = [tex]\frac{35}{4}[/tex]
[tex]\frac{35}{4}[/tex] x [tex]\frac{3}{1}[/tex] = [tex]\frac{105}{4}[/tex] = 26.25 = 26 [tex]\frac{1}{4}[/tex]

There is a pair of parallel sides in the following shape.
10
2
2
What is the area of the shape?
The area of the shape is 12 square units
Area of a trapeziumThe given shape is a trapezium and the formula for calculating the area of a trapezium is expressed as:
A = 0.5(a+b)h
Given the following parameters
a = 2
b = 10
h = 2
Substituting the given parameters
A = 0.5(2+10)*2
A = 0.2(12) * 2
A = 12 square units
Hence the area of the shape is 12 square units

What is the trigonometric ratio for sin C?
Enter your answer, as a simplified fraction.
Answer:
(9/40)
Step-by-step explanation:
Sin is Opposite/Adjacent
sin(C) = AB/BC
We can find the value of AB by using the Pythagorean Theorem:
a^2 + b^2 = c^2
(80)^2 + b^2 = (82)^2
b = 18
sin(C) = 18/80 or (9/40)
If A = 2x - 722 + 3 and B = 4x2 - 12x, what is A + B?
A) -3x^2+10x+3
B) -3x^2-10x+3
C)3x^2-10x+3
D)6x^2-7x-9
Answer:
B
Step-by-step explanation:
Combine like terms. Like terms have same variable with same power.
2x & (-12x) are like terms and
-7x² & 4x² are like terms
A = 2x - 7x² + 3
B = 4x² - 12x
A + B = 2x - 7x² + 3 + 4x² - 12x
= 2x - 12x - 7x² + 4x² + 3
= (2-12)x + (-7 + 4)x² + 3
= -10x + (-3x²) + 3
= -3x² - 10x +3
Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side NK.
Figures are not drawn to scale.
Answer:
NK = 14.4
Step-by-step explanation:
Given the following question:
We know that the two sides are similar
JI = 3, NM = 7.2
The scale factor is 2.4 since....
[tex]3\times2.4=7.2[/tex]
Knowing the two sides are similar and if we multiply JI by 2.4, we get NM we can easily do the same for JG and NK.
JG = 6
[tex]6\times2.4=14.4[/tex]
[tex]=14.4[/tex]
NK = 14.4

26=-12y-9+7y what is this answer
Answer:
[tex]y = - 7[/tex]
Solving steps:
=> 26=-12y-9+7y
Step 1: Simplify both sides of the equation.
make y the subject of formula
=> 26=−12y+−9+7y
=> 26=(−12y+7y)+(−9)
Combine like terms
=> 26=−5y+−9
=> 26=−5y−9
Step 2: Flip the equation.
=> −5y−9=26
Step 3: Add 9 to both sides.
=> −5y−9+9=26+9
=> −5y=35
Step 4: Divide both sides by -5.
.=> [tex] \frac{ - 5y}{ - 5} = \frac{35}{ - 5} [/tex]
=> y = - 7

Connor needs 60 mL of a 19% acid solution for a science experiment. He has available a 21% solution and a 15% solution.
How many milliliters of the 21% solution and how many milliliters of the 15% solution should he mix to make the 19%
solution?
Answer:
Let x = ml of 21% solution
Let y = ml of 15% solution
ATQ,
x + y = 60.....(1)
or
0.21x + 0.15y = 0.6....(2)
Multiplying equation 1st by 0.21, we get,
0.21y+0.21y =12.6....(3)
subtracting equation 3
0.21y+0.21y =12.6
-0.21x +0.15y = 0.6
_________________
ㅤㅤㅤ 0.6y = 12
_________________
6y = 12
y = 20ml
x= 60-20 = 40 ml
Hence , Conner needs 20ml of 21% solution & 40ml of 15% solution

joy is (4x + 5) years old her brother micheal is (3x - 2) years younger than her sister. then write an expression thet represents Michael's age
Answer:
(x +7) years old
Step-by-step explanation:
Joy= (4x +5) years old
Since Michael is (3x -2) years younger, we need to subtract (3x -2) from Joy's age to find out his age.
Michael
= (4x +5) -(3x -2)
= 4x +5 -3x +2 (expand)
= x +7
Thus, Michael is (x +7) years old.

(2x+3y-7)+(x-y)
show how you got the answer too please
Answer:
3x +2y -7
Step-by-step explanation:
The given expression can be simplified by combining like terms. Those are terms with the same variable. The commutative and associative properties of addition apply, as well as the distributive property.
(2x +3y -7) +(x -y) . . . . . given
= 2x +3y -7 +x -y . . . . . . eliminate (unneeded) parentheses
= (2x +x) +(3y -y) -7 . . . . group like terms
= (2+1)x +(3-1)y -7 . . . . . . combine coefficients of like terms (this is an application of the distributive property)
= 3x +2y -7

Hope it helps you<3Is negative one a rational number?
Answer: -1 is a rational number.
Step-by-step explanation: -1 is a rational number because it is an integer. An integer can be any number, such as -5, 5, 0, 3, etc.
Rational numbers can also be perfect squares (i.e square root of 25), it can be repeating decimals or decimals in general.
Irrational numbers are numbers that cannot be written as a fraction OR that are imaginary.
Irrational numbers would be repeating decimals that do not have the same values repeated, such as Pi. Pi cannot be written as a fraction, only estimated. Irrational numbers can also be imaginary numbers such as the square root of -4. There is no number in this world that can multiply itself and become -4. A negative times a negative is positive, and a positive times a positive is a positive. This means the square root -4 is imaginary and therefore irrational.
Answer:
Yes.
Step-by-step explanation:
All integers, fractions, whole numbers & natural numbers fall into the category of rational numbers.
How are integers rational numbers?
The definition of rational numbers says that any number that can be written in the form of p/q, where p & q are integers & q is not equal to 0 are categorised into rational numbers. This is in the form of the fraction. We know that, by dividing the integers by 1, we'll get them as a fraction. Sp, integers are rational numbers.
For example:
- 1 = -1/1 (p/q form; so it's a rational number)
