Maya makes trail mix by combining 1/2 cup of mixed nuts, 1/4 cup of dried fruit, and 1/8 cup of chocolate morsels. What is the total amount of ingredients in her trail mix? Explain how you solved the problem.
Answer:
7/8 ingridents
Step-by-step explanation:
If you're working with improper fractions where the numerators are larger than the denominators, make the denominators the same. Then add the numerators. If you're adding mixed numbers, turn them into improper fractions and make each fraction equivalent. This will make it easy to add the fractions together.

Aaron and two friends went to the movies and spent a
total of $33. The group bought a box of popcorn to
share that cost $ 6. What was the cost of each movie
ticket?
Answer:
6 + (t x 2) = 33
T = Ticket Cost
6 - 6 + (t x 2) = 33 - 6
t x 2 = 27
t x 2/2 = 27/2
t = 13.5
Each ticket cost 13.50$

Katherine's paycheck was $436.14. She put 1/3 of her paycheck into a savings acount and used 1/2 for what was left to pay for her new phone,
How much money does she have remaining from her paycheck?
Answer:
$145.38
Step-by-step explanation:
436.14-(1/3)(436.14)-(1/2)(436.14) = 145.38
The amount of money that Katherine left after considering all fractions will be $145.38.
What is a fraction?In such a fraction, the value that appears above the horizontal line is referred to as the numerator.
The denominator of a fraction is the numerical value that comes before the brings together various.
It represents the number of pieces removed from the whole.
As per the given,
Initial amount = $436.14
1/3 of it is = (1/3)436.14 = $145.38
Since, she saved into a saving account so she left with,
$436.14 - $145.38 = $290.76
Now,1/2 of it will be,
(1/2)290.76 = $145.38.
Hence "The amount of money that Katherine left after considering all fractions will be $145.38".

Use the following diagram to find the angle measures of the triangle, rounded to the nearest degree.
m∠A=
m∠B=
m∠C=
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]
[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
Use a Pythagorean Triple to find x.
Answer:
x = 51
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² = 45² + 24² = 2025 + 576 = 2601 ( take the square root of both sides )
x = [tex]\sqrt{2601}[/tex] = 51
Answer:
x = 51.
Step-by-step explanation:
The triple you require is 17-15-8
We have x-45-24
- that is three times each number in the triple.
So x = 3*17 = 51.

()) There are two cubes. The first cube has a volume of 1,000 cubic units. The second cube is smaller than the first, with sides only half as long. What is the volume of the second cube? D) cubic units Submit
Answer:
125 units^3
Step-by-step explanation:
Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.
You then divide the sides by 2 because the question says the second cubes sides are half the size
5*5*5 = 125
The volume of the second cube is 125 units³.
What is volume?In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.
Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.
We need to find the volume of the second cube,
So, let the side of the first cube be x,
We know that the volume of a cube = side³
Therefore,
x³ = 1000
x = ∛1000
x = 10 units
Therefore, the second cube will have a side of 10/2 = 5 units
Volume of second cube = 5³ = 125 units³.
Hence the volume of the second cube is 125 units³.

Marketing entrepreneurs choose a marketing niche first to prepare to launch their business. Thus, option B is correct.
What is marketing niche?The portion of a market that a particular product is targeted toward is called a niche market. The product's market niche determines its price range, level of production, target demographics, and feature set that is intended to address a particular market need. Additionally, it is a small market sector. A product or service may occasionally be created specifically to meet the needs of a niche market.
Not all products can be classified by their market niche. The highly specialised niche market competes against numerous super companies and strives to remain viable. Even well-known companies develop products for specific markets; Hewlett-Packard produces separate machines in addition to all-in-one printing, scanning, and faxing units that are aimed at the home office market.

What is the lateral area of the regular pyramid if the area of the square base is 36 square cm and the slant height is 12 cm? options: 168 144 72 298
Step-by-step explanation:
Given that,
The area of the square base, A = 36 cm²
Slant height, s = 12 cm
We need to find the lateral area of the regular pyramid. The formula is :
[tex]S=A+\dfrac{1}{2}p\times s[/tex]
Where
A is the area of base
p is perimeter of base
s is slant height
Area of square, A = side²
So,
[tex]side=6\ cm[/tex]
Put values in the above formula.
[tex]S=36+\dfrac{1}{2}\times 4\times 6\times 12\\\\=36+144\\\\=180[/tex]
So, the lateral area of the regular pyramid is equal to 180 cm².
