Answer: The answer is 8000 pounds, or 4 tons

Step-by-step explanation:

This is true because each tree makes about 250 pounds of oxygen. She counted 32 so.....

(32)(250)=8000

then convert 8000 pounds to tons and you get 4 tons

If a = 0.3 and b =0.5, what is the value of a+b?
Alborosie

Answer=

D

Step-by-step explanation

because of the dot/line at the top of the number it means it is a continuous same number

for example, 0.3 with a dot/line on top means it is 0.333333...

so 0.55...+0.33...=0.88...

and as it is a decimal that is in the range of 1-100 its like a percentage so it is 88/100

Will give brainliest!!! please help
Firdavs [7]

Answer:

10.8 m²

Step-by-step explanation:

To find area, we do 3.14*r^2

since diameter = 2 radius divide each by 2

2 and 0.75

A outer= 3.14*2^2

3.14*4

12.56 m²

A inner = 3.14*0.75^2

≈1.8 m²

to find the shaded area subtract the outer from the inner

12.56-1.8=10.76

which rounds up to

10.8 m²

If we use π then we get

about

12.57

and

1.77

subtract to get

10.8 m²

the length of a rectangle is 4 meters less than twice its width. The area of the rectangle is 70. Find the dimensions of the rec
Savatey [412]

Answer:  The width is 7 meters. The length is 10 meters.

Step-by-step explanation:   Area = Length × width

Length is 2w - 4  

Substitute that value for length, then solve for w.

70 = w(2w - 4)

70 = 2w² - 4w  reorganize to quadratic equation form

2w² - 4w -70 = 0   These are All even numbers; factor out 2 (divide all by 2)

w² - 2w - 35 = 0  factor this

(w - 7)(w + 5)    set each factor = 0 and calculate the value of w.

w+5=0  w= -5  (disregard this one because dimensions of real rectangles can't be negative)

w - 7 = 0  w = 7   <u>The width is 7</u>

Substitute into the original expressions to get the value of Length.

2(7) -4 = L    14 - 4 = L  The<u> Length is 10.</u>

Check by substituting into the original equation:

w × 2w -4 = 70

7 × 2(7) -4 = 70

7 × 10 = 70    TRUE!

w
