svetlana [45]

<em>Answer:</em>

<em>Step-by-step explanation:</em>

<h2><u><em>21u²</em></u></h2>

The formula for the area of a parallelogram is base times height

so

x = 7 (base)

y = 5

h = 3 (height)

7 * 3 =

Because Charles David Keeling and his new colleagues began measuring CO2 in 1958, we now have an excellent record of how CO2 con
Alecsey [184]

Answer:

1. 516 ppm; 2. 561 ppm

Step-by-step explanation:

1. CO₂ increase at old rate

Time = 2100 - 2010 = 90 years

Increase in CO₂ = 90 yr × (1.4 ppm/1 yr) = 126 ppm

CO₂ in 2010 = 390 + 126 = 516 ppm

At the old rate, the CO₂ concentration in 2100 will be 516 ppm.

2. CO₂ increase at new rate

Time = 2100 - 2010 = 90 years

Increase in CO₂ = 90 yr × (1.9 ppm/1 yr) = 171 ppm

CO₂ in 2010 = 390 + 171 = 561 ppm

At the new rate, the CO₂ concentration in 2100 will be 561 ppm.

Amanda makes colored paper cone cups to serve nuts at a charity event. The height of each paper cone is 15 centimeters, and the
allsm [11]

Answer:

V=261.80 \ cm^3

Step-by-step explanation:

-The volume of a cone is given by the formula:

V=\pi r^2 \frac{h}{3}

Where:

  • r is the cone's radius.
  • h is the cone's height.

#We substitute for r and h in the formula to solve for V:

V=\pi r^2 \frac{h}{3}\\\\=\frac{1}{3}\pi \times 5^2\times 10\\\\=261.80\ cm^3

Hence, the each cone's volume is 261.80 \ cm^3

const2013 [10]

Answer:

if Im correct it should be $8.40

Step-by-step explanation:

why well if you think of breaking down by say 1/4 of 168 all you do is divide 4 which is the whole amount by 0.2 which is the amount the father gave her so 4/0.2= 20 the you take your whole 168 and divide by 20 which the whole number for 0.2 the your answer should be this 168/20= 8.4 which then i assumed it was $8.40 hopefully that is correct hehe
