Answer:
1/2 of the original pizza is left over
Step-by-step explanation:
When solving this question, divide 8 by 4. That will give you one fourth of the pizza. Multiply that by three, and you will get 6. Then divide 6 by 3, to get 2 as one third of 6.
Subtract 2 from 6 to get 4
Find the length of side AB.
Give your answer to 1 decimal place.
CB = 12 cm
AB = 62°
PLEASE HELP!!
Answer:
AB ≈ 5.6 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )
12 × cos62° = AB , then
AB ≈ 5.6 cm ( to 1 dec. place )
The sum of three numbers is 105. The third number is 2 times the first. The first number is 5 less than the second. What are the numbers?
Answer:
The second number = 30
The first number = 25
The third number = 50
Step-by-step explanation:
Let
The second number = x
The first number = x - 5
The third number = 2(x - 5)
Total = 105
105 = x + (x - 5) + 2(x - 5)
105 = x + x - 5 + 2x - 10
105 = 4x - 15
105 + 15 = 4x
120 = 4x
x = 120/4
x = 30
The second number = x
= 30
The first number = x - 5
= 30 - 5
= 25
The third number = 2(x - 5)
= 2(30 - 5)
= 2(25)
= 50

This table shows how much each type of meat costs at a local deli.
Type of Meat Price per Pound
Ham $5.99
Turkey $4.99
roast beef $6.99
salami $2.99
bologna $3.99
A customer purchased 1/ 4 pound of ham, 1 1/2 pounds of turkey, 1 pound of roast beef, and
3/ 4 pound of bologna. Approximately what will the customer pay before taxes
The price that the customer pay before taxes is $18.965.
What is Multiplication?Multiplication of two numbers is defined as the addition of one of the number repeatedly until the times of the other number.
a × b means that a is added to itself b times or b is added to itself a times.
Given a table which shows the unit price of the meat at a local deli.
A customer purchased 1/ 4 pound of ham, 1 1/2 pounds of turkey, 1 pound of roast beef, and 3/ 4 pound of bologna.
In order to get the price of each meat, multiply unit price with the amount that the customer buy.
Total price = (1/4 × $5.99) + (3/2 × $4.99) + (1 × $6.99) + (3/4 × $3.99)
= $18.965
Hence the total price paid is $18.965.

Answer:
If <1 and <2 are complementary, and <2 and < 3 are complementary, then <1 and < 3 are also complementary.
Step-by-step explanation:
Two angles are complementary when they add up to the same whole. For example, two angles are complementary when they add up to 90 degrees. This is a simple "if A=B, and B=C, then A=C" situation. The angles may have different degrees but all add up to the same one, making them complementary.
a) Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x = 1
Answer:
Since [tex]f(0) < f(x) < f(1)[/tex], there is a solution for [tex]f(x)[/tex] between [tex]x = 0[/tex] and [tex]x = 1[/tex].
Step-by-step explanation:
A solution of the polynomial is a root such that sign of dependent value changes, either from positive to negative or from negative to positive. Let [tex]f(x) = x^{3} + 6\cdot x - 5[/tex], [tex]x[/tex] is a solution of the equation if and only if [tex]f(x) = 0[/tex]. We proceed to evaluate the function at each bound:
x = 0
[tex]f(0) = 0^{3}+6\cdot (0) - 5[/tex]
[tex]f(0) = -5[/tex]
x = 1
[tex]f(1) = 1^{3}+6\cdot (1) - 5[/tex]
[tex]f(1) = 2[/tex]
Since [tex]f(0) < f(x) < f(1)[/tex], there is a solution for [tex]f(x)[/tex] between [tex]x = 0[/tex] and [tex]x = 1[/tex].

The Equation:
[tex]\frac{p\\}{6}[/tex] = 4What we know:
The pencils were divided into 6 groups of 4.
The variable for pencils is P.
Step-by-step explanation:
So, to find the equation we plug-in P over 6 because we are dividing the pencils into 6 groups. We plug in the number 4 in the right-hand box because it represents the number which is in each group. So this equation shows that the Pencils (P) is split into 6 groups with 4 pencils in each group.

Answer:
3(4a+8b)
Step-by-step explanation:
12a + 24b
= The common multiple between 12 and 24 is 3
3(4a + 8b)
Hence the expression which is equivalent to 12a + 24b is 3(4a+8b)
The volume of a cube is 8 in^3 What is the length of one side?
2.7in3
2 in3
2.7 in
2 in
Answer:
2 in
Step-by-step explanation:
Use the cube volume formula, V = s³, where s is the side length
Plug in 8 as V and solve for s:
V = s³
8 = s³
Take the cube root of both sides:
2 = s
So, the length of one side is 2 inches.
The length of one side of cube will be 2 in i.e. option D.
What is volume ?Volume is the amount of space that something contains or fills.
Volume of the cube = side³ = a³
We have,
Volume of the cube = 8 in³
And,
Side of cube = a
So,
Volume of the cube = side³ = a³
i.e.
8 = a³
⇒ a³ = 8
a = ∛8
On solving we get,
a = 2
i.e.
Side of cube = 2 in
Hence, we can say that the length of one side of cube will be 2 in i.e. option D.

Answer: 62 degrees
Step-by-step explanation:
Answer:
62 degrees
Step-by-step explanation:
If the angles are represented in degrees, find both angles:
cos(8x+18)=sin(−2x+36)
Answer:
24 and 66degrees
Step-by-step explanation:
Given the equation
cos(8x+18)=sin(−2x+36)
In trigonometry identity, cos theta = sin (90- theta)
The given expression becomes;
sin (90 - (8x+18)) = sin(−2x+36)
sin will cancel out to have;
90 - (8x+18) = (−2x+36)
90-8x-18 = -2x+36
-8x +72 = -2x+36
-8x + 2x = 36 - 72
-6x = -36
x = 36/6
x = 6
Hence the value of x is 6
cos(8x+18) = cos(8(6)+18)
= cos 66
Also
sin(−2x+36)
= sin(−2(6)+36)
= sin(−12+36)
= sin 24
Hence both angles are 24 and 66degrees

need help please
Answer:
-15
Step-by-step explanation:
We have the expression 3(2p - 5) - 6p and are asked to simplify.
Let's distribute, which is to multiply a number that is outside of a parenthesis bracket by the numbers inside the parenthesis.
3(2p - 5) - 6p
(3(2p) - 3(5)) - 6p
6p - 15 - 6p
Since you can only do changes to like terms and 15 and 6p are two different terms, we do 6p - 6p.
6p - 6p
0
Leaving us with -15.
Answer:
-15
Step-by-step explanation:
Simplify each term.
6p - 15 - 6p
Combine the opposite terms:
Subtract 6p from 6p

The given expression can be written in the form of b√2 as 12√2 where b = 12.
What is an Algebraic expression?An algebraic expression can be obtained by doing mathematical operations on the variable and constant terms.
The variable part of an algebraic expression can never be added or subtracted from the constant part.
The given expression is [tex]14/\sqrt{2}+\sqrt{50}[/tex].
It can be rewritten as,
[tex]14/\sqrt{2}+\sqrt{50}[/tex]
Multiply √2 to both numerator and denominator of 14/√2 as,
14√2/2 + √50
⇒ 7√2 + √(5 × 5 × 2)
⇒ 7√2 + 5√2 = 12√2
On comparing 12√2 with b√2, it is obtained as,
b = 12
Hence, the given expression can be written as 12√2.
