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)
Answers
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.

Yannick bought a bicycle. He paid $194.25, including tax. If the sales tax rate is 5%, how much did Yannick pay for tax?
Answers
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.**

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?
Answers
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 ]

58,000,000 km

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?
Answers
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

∠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..
Answers
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
