Table for the question :

Students ____ minutes per day

Leah _________45

Roberts _______17

Jules _________36

Apollo _______ 24

Calculate the Number of calories each student burn for 1 day of activity :

Answer:

Leah =. 630

Jules = 504

Roberts = 306

Apollo = 432

Step-by-step explanation:

Given that:

Skating burns 14 calories per minute

Running burns 18 calories per minute

Number of calories each student burn for 1 day of activity :

SKATING ;

Leah: = 14 * 45 = 630

Jules = 14 * 36 = 504

RUNNING ;

Roberts : 18 * 17 = 306

Apollo : 18 * 24 = 432

An airplane climbs at an angle of 2.7" from an altitude of 4500 ft to an altitude of 5600 ft. How far does the airplane travel a
Dvinal [7]

Answer:

  23,325 ft, about 4.42 miles

Step-by-step explanation:

The geometry of the situation can be modeled by a right triangle, where the side adjacent to the 2.7° angle of climb is the horizontal distance, and the side opposite is the vertical change in altitude. That change is ...

  5600 ft -4500 ft = 1100 ft

and the angle relation is ...

  tan(2.7°) = opposite/adjacent = (1100 ft)/(horizontal distance)

Multiplying this equation by (horizontal distance)/tan(2.7°) gives ...

   horizontal distance = (1100 ft)/tan(2.7°) ≈ 23,325 ft

Dividing this by 5280 ft/mi gives ...

  horizontal distance ≈ 4.42 mi

The airplane travels about 23,325 ft, or 4.42 miles, horizontally as it climbs.

You are volunteering to help with the soccer team fundraiser for Valentine's Day. Your team promised to deliver one 16 ounce bag
icang [17]

The student, who suggests that if we do half and half of each bag, we will be giving them at least 60%,<u> is correct</u>.

<h3>What is the implication of the phrase "at least"?</h3>

The phrase "at least" means the minimum that is true or possible.

Mathematically, by "at least," we mean 'equal to or greater than.'

<h3>Data and Calculations:</h3>

Since each bag of nuts contain 16 ounces,

The 1st bag contains x/2 ounces (50%) of plain nuts and x/2 ounces (50%) of chocolate-covered nuts.

The 2nd bag contains x/5 ounces (20%)of plain nuts and 4x/5 ounces (80%) of chocolate-covered nuts.

If half of the 1st bag is mixed with half of the 2nd bag, each bag will contain only 65% (that is, 25% (50%/2) from the 1st bag and 40% (80%/2) from the 2nd bag).

Thus, the student, who suggests that if we do half and half of each bag, we will be giving them at least 60%, <u>is correct</u> since they will not be given less than 60% of chocolate-covered nuts inside.

Someone help me on these 2 questions asap! 50 points!!
anyanavicka [17]

Step-by-step explanation:

earbuds

we have a 1in : 0.2in scale of drawing to reality.

0.2 = 2/10 = 1/5

so, 1in in the drawing is actually 1/5in in reality.

how long are the 4in in the drawing ?

well, 4 times the 1in thing.

4×1/5 = 4/5 = 0.8in long

again the similar triangles

similar triangles means that each pair of corresponding lines (sides, heights, ...) in the triangles follows the same scaling factor for the length.

so, what do I need to multiply the side of the large triangle with to get the corresponding side length of the small triangle ?

27 × x = 9

x = 9/27 = 1/3

and that is the scale factor.
