−11.57
−11.60
−21.74
−22.25

I WILL GIIVE BRAINIEST AND THANKS

Answers

Answer 1

Answer: -22.25

Step-by-step explanation:

I think this is how to do it but the way you explained the expression was slightly confusing but I set it up like this:

(3/10)^2 - 17 + (-7/ | 4.3 - 7.8 |) x 2.67

then when I simplified the expression I received an answer of -22.23 which is close to one of the given answers of -22.25

Hopefully this was correct, sorry that I couldn't be of more help

A groundskeeper needs grass seed to cover a circular field, 290 feet in diameter. One pound of grass seed covers about 400​ square feet of field.

How many pounds of grass seed should the groundskeeper buy to cover the circular field?

-EXPLAIN YOUR RESONING-

Answers

Answer:165.13 pounds of grass seed.

Step-by-step explanation: to find the area of a circle you must do the equation pi r^2, so in this case that is pi*145, because radius is half the diameter, and that gets you approximately 66051.99 ft^2. when you divide 400 by this number, you get approximately 165.13 pounds of seed.

An object has a mass of 17 grams.

What is its weight in ounces?

Use 1 ounce=28.35 gram to write the conversion facto

Answers

0.6 oz would be objects weight in ounces

Step-by-step explanation:

In order to determine the weight of an object in ounces, we need to convert its mass from grams to ounces using the conversion factor of 1 ounce = 28.35 grams. Since the mass of the object is 17 grams, we can use the conversion factor to calculate its weight in ounces as follows:

17 grams * (1 ounce / 28.35 grams) = 0.6 ounces

Therefore, the weight of the object in ounces is 0.6 ounces. The conversion factor used in this calculation is 1 ounce = 28.35 grams.
