He is at sea level after 34 seconds

Step-by-step explanation:

The height at sea level is given as 0 meters

So the change in height would be;

0- (-17) = 17 meters

There is a gain of 0.5 meters in 1 second

So, the time taken for it to gain 17 meters will be 17/0.5 = 34 seconds

Answer:

$26.25

Step-by-step explanation:

We are told that Marco needs to buy some cat food. At the nearest store, 3 bags of cat food cost $15.75.  

First of all we will find cost of 1 bag of cat food by dividing 15.75 by 3.

Now we will find the amount that Marco has spend for 5 bags of cat food by multiplying 5.25 by 5.  

Therefore, Marco has spend $26.25 for purchasing 5 bags of cat food.    

Answer:

5.25 per bag

Step-by-step explanation:

Just divide the amount of money by the number of bags needed.

15.75 divided by 3 = 5.25

Answer:

2.775 or if you want to say in terms of money it would be $2.78

Answer:

i dont know which one to choose but chicken tenders

Answer:

Chicken tenders.

Step-by-step explanation:

Chicken nuggets are the gross consumption of organs including lungs and others mushed together and fried. In return kids run to it because (most) kids only eat gross stuff. This made the marketing campaign SKY ROCKET with kids everywhere trying to get a bite. FORCING their poor parents to get them that disgusting mush. And then dip it in ketchup. Which is NOT a fruit or veggie. (As the school system thinks they are a veggie.)

While chicken tenders are chopped off the chicken meat then rolled in bread crumbs. And then deep fried to make a crispy exterior with a delicious tender interior.  Without getting mushed together with other things.

Also you never know what they put in that chicken nugget since its mushed together ‍♀️.

Answer: It's a right triangle

Answer: It is a right triangle.

the attachment shows the graphed triangle.

Step-by-step explanation:  The slope of the line between coordinates (-2,-3) and (2,1) is +1  rise/run is 4/4

The slope of the line between points (2,1) and (5,-2) is -1 rise/run -3/3

These slopes are perpendicular to each other, so they form the right angle of this triangle.

Step-by-step explanation:

The surface area of one box is 62 square inches.

The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.

Given that, Yolanda makes wooden boxes for a crafts fair.

The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.

We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)

Now, surface area = 2(5×3+3×2+2×5)

= 2(15+6+10)

= 2(31

= 62 square inches.

Therefore, the surface area of one box is 62 square inches.

Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Step-by-step explanation:

We need to u se a vertical format to subtract the polynomials.

The polynomials given are:

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]

Now, solving

For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -

The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)

[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]

So, Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]

Answer:

First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).

Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).
