The sum of three consecutive numbers is 537. What is the 3rd number?

maks197457 [2]

For this problem your equation will be x+(x+1)+(x+2)=537

Multiply and Simplify:

x+x+1+x+2=537

3x+3=537

Subtract 3 from both sides:

3x+3-3=537-3

3x=534

Divide both sides by 3:

3x/3=537/3

x=179

179 is the middle number so: 178+179+180=537

180 is the third number.

Dina and Masha started out on a 12 mi bike path at the same time. When Dina reached the end of the 12 mi, Masha still had 3 mi l

Anna35 [415]

Answer:

6 mph

Step-by-step explanation:

Use formula

$D=r\cdot t,$

where

D = distance

r = rate

t = time

In your case,

D = 12 mi

Dina:

D = 12 mi

r = 8 mph

t = ?

So,

$12=8t\\ \\t=\dfrac{12}{8}=\dfrac{3}{2}=1.5\ hours$

Masha:

D = 12 - 3 = 8 mi

r = ?

t = 1.5 hours

Then

$9=1.5r\\ \\r=\dfrac{9}{1.5}=\dfrac{90}{15}=6\ mph$

2. Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular py

zalisa [80]

Answer:

$124.16$ cubic meter of clay will be used to create all the pyramids

Step-by-step explanation:

The remaining part of the question is given in the attached file

Solution

The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.

For Rectangular Pyramid,

Volume of three rectangular pyramids

$3 * \frac{BH}{3} = BH$

Substituting the given values in above equation, we get -

$15.5 * 5 = 77.5$ cubic centimeter

For triangular Pyramid,

Volume of two triangular pyramids

$2 * \frac{BH}{3}\\2 * \frac{10 * 7}{3}$

$46.67$ cubic centimeter

Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid $= 77.7 + 46.67 = 124.16$ Cubic centimeter
