Cy has 42 baseball cards & 70 football cards that he wants to group into packages. Each package will have the same number of cards, and each package will have the same numbers of baseball cards and football cards. How many packages will Cy make if he uses all the cards?
Answer:
The answer is 14
Step-by-step explanation:
14
Answer:
Cy has 42 baseball cards and 70 football cards
he wants to group them into packages with each package having the same number of cards of both types
so we have to find the highest common factor for 42 and 70 so they can be divided into packages equally and each package having an equal number of cards
the factors for 42 and 70 are as follows
42 - 1,2,3,6,7,14,21,42
70 - 1,2,5,7,10,14,35,70
the highest factor common for both is 14
therefore Cy can make 14 packages
each package will have
42/14 = 3 baseball cards
70/14 = 5 football cards
so each package will have 3 baseball cards and 5 football cards
Cy can make 14 packages

The length of a rectangle is 5 times larger than x. The width is 4 cm less than the length. The perimeter is at least 96 cm. What are the smallest possible dimensions for the rectangle?
We know that the perimeter of a rectangle = 2(l + w)
l = length
w = width
In our problem,
l = 5x
w = 5x - 4
Let's create an inequality to help us solve this problem.
2(5x + (5x - 4)) ≥ 96
Let's start off by simplifying the terms inside the parentheses.
2(10x - 4) ≥ 96
Distribute the 2
20x - 8 ≥ 96
Add 8 to both sides.
20x ≥ 104
Divide both sides by 20
x ≥ 5.2
Let's plug 5.2 into x for our length and width.
Length = 5x = 5(5.2) = 26 cm
Width = 5x - 4 = 5(5.2) - 4 = 26 - 4 = 22 cm
The smallest possible dimensions for the rectangle are, length = 26 cm and width = 22 cm
Answer:
width = 10 cm
length = 14 cm
The smallest dimension is 10 cm.
Step-by-step explanation:
2x + 2(x + 4) ≥ 48
Solve for x.
2x + 2x + 8 ≥ 48
4x + 8 ≥ 48
4x ≥ 40
x ≥ 10

The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025 cm.
Part A) What is the distance from the sun to Mercury written in scientific notation?
Part B) What is the diameter of a human hair written in scientific notation?
Part C) In comparing the measurements in Parts (a) and (b), what else must be done before a comparison is made?
Answer:
Distance of Sun and Mercury = 58,000,000 km.
In Scientific notation, it would be: 5.8 × 10⁷ Km
Diameter of a human hair = 0.0025 cm
In scientific notation, it would be: 2.5 × 10⁻³ cm
Before Comparison, we need to bring to or vice-versa, so we can easily calculate then, here, we will go from cm to Km.
2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸
Now, we can compare the values,
5.8 × 10⁷ Km > 2.5 × 10⁻⁸
[ reason. - power of smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]
Answer:
58,000,000 km

While scuba diving, Rajeev dove to a depth of 12.6 feet below the surface of the water and then descended another 8.7 feet. What expression can be used to find Rajeev’s new position?
12.6 – 8.7
–12.6 – 8.7
–12.6 – (–8.7)
12.6 – (–8.7)
The required expression is 12.6 - (-8.7) can be used to find Rajeev’s new position.
What is the algebraic expression?Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.
To find Rajeev's new position, we need to add the depths of his two descents.
Since the first descent was to a depth of 12.6 feet below the surface of the water, and the second descent was to a depth of 8.7 feet below the surface of the water, Rajeev's new position is 12.6 + 8.7 = 21.3 feet below the surface of the water.
Therefore, the expression we are looking for is 12.6 + 8.7 = 21.3. This is the same as the fourth option: 12.6 - (-8.7) = 21.3.

∠A and \angle B∠B are complementary angles. If m\angle A=(2x+30)^{\circ}∠A=(2x+30)
∘
and m\angle B=(6x-12)^{\circ}∠B=(6x−12)
∘
, then find the measure of \angle A∠A..
Answer:
∠A = 48
Step-by-step explanation:
∠A + ∠B = 90 ( Complementary angles)
2x + 30 + 6x - 12 = 90
Combine like terms
2x + 6x +30 - 12 = 90
8x + 18 = 90 {subtract 18 form both sides}
8x = 90 - 18
8x = 72 {Divide both sides by 8}
8x/8 = 72/8
x = 9
∠A = 2x + 30
= 2*9 + 30
= 18 + 30
∠A = 48
Given a value for the in put variable x, and the output variable y, calculate the constant of proportionality. x = 60, y = 18.

Answer:
x = 15
Step-by-step explanation:
Given
3(x - 8) + 4 - 2x = - 5 ← distribute and simplify left side
3x - 24 + 4 - 2x = - 5
x - 20 = - 5 ( add 20 to both sides )
x = 15
Answer:
x = 15
Explicación paso a paso:
Dado
3 (x - 8) + 4 - 2x = - 5 ← distribuir y simplificar el lado izquierdo
3x - 24 + 4 - 2x = - 5
x - 20 = - 5 (suma 20 a ambos lados)
x = 15

Are these functions: 1. In a class of ninth graders, the relationship between shoe size (x-axis) and height (y-axis). 2. in a class of ninth graders, the relationship between student (independent variable) and height (dependent variable).
Answer:
Your answer depends on the numbers showed to you.
Step-by-step explanation: To find your answer you need to look at the numbers on the x-axis are they the same repeating number each time(-1,9),(2,3),(4,-3)(-1,7) if they look like the example I just gave you then it is not a function. If the x-axis has all different number then yes it is a function.
The scenario 1 is not a function, while the scenario 2 is a function
How to determine the functions?Scenario 1:
The relationship is between:
The shoe size on the x-axisThe height on the y-axisIt is true that a certain shoe size can belong to students of different heights.
This means that the relation is a one-to-many relation
A one-to-many relation is not a function;
Hence, this is not a function
Scenario 2:
The relationship is between:
Independent variable: StudentDependent variable: HeightIt is true that a student can have only one height.
This means that the relation is a one-to-one relation
A one-to-one relation is a function;
Hence, this is a function

Yannick bought a bicycle. He paid $194.25, including tax. If the sales tax rate is 5%, how much did Yannick pay for tax?
Answer:
$9.71 or $203.96
Step-by-step explanation:
5% of $194.25 is $9.71
if you wanted the overall cost that would be $203.96.
Answer:
$11.00 in sales tax
Explaination:
To find the sales tax from total bill, you would divide the total amount by "1 + the sales tax rate" (i.e., If the sales tax is 5%, divide the total amount by 1.05."
Soooo....
194.25 / 1.05 = 183.25**
** Now take that total and subtract it from the full total amount of 194.25.
194.25 - 183.25 = $11.00**
** This total is the amount of sales tax charged.**
