The graph shows the type and number of coins that three students plan to donate during a coin drivefundraiser.Coin Drive Donatio

yarga [219]

Answer:

39 dimes

Explanation:

From the graph:

• Total number of nickels = 9+4+7=20

• Total number of dimes = 7+10+9 = 26

The ratio of total nickels to total dimes = 20:26

If the total number of nickels the students donate is increased to 30, we have:

$\frac{\text{Total Nickels}}{\text{Total Dime}}\colon\frac{20}{26}=\frac{30}{x}$

We then solve for x:

$\begin{gathered} 20x=30\times26 \\ x=\frac{30\times26}{20} \\ x=39 \end{gathered}$

The number of dimes they should donate to keep the ratio of total nickels to total dimes the same is 39.

A figure is broken into a rectangle and a triangle. The triangle has a base of 2 and two-thirds feet and height of 3 feet. The r

ohaa [14]

Answer:

$b=2\frac23\:\sf ft$

Area of triangle = 4 ft²

Area of rectangle = $6\frac23\: \sf ft^2$

Area of irregular figure = $10\frac23\: \sf ft^2$

Step-by-step explanation:

$\begin{aligned}\sf Base\:of\:triangle\:(b) & = 5-2\frac13\\\\& = \dfrac{15}{3}-\dfrac73\\\\ & = \dfrac83\\\\ & = 2\frac23\:\sf ft \end{aligned}$

$\begin{aligned}\sf Area\:of\:a\:triangle & =\dfrac12 \sf \times base \times height\\\\& = \dfrac12 \times b \times 3\\\\ & = \dfrac12 \times \dfrac83 \times \dfrac31\\\\ & = \dfrac{24}{6}\\\\ & = 4\: \sf ft^2\end{aligned}$

$\begin{aligned}\sf Area\:of\:rectangle& =\sf length \times width\\\\& = 5 \times 1\frac13\\\\ & = \dfrac51\times \dfrac43\\\\& = \dfrac{20}{3}\\\\ & = 6\frac23\: \sf ft^2\end{aligned}$

$\begin{aligned} \sf Area\:of\:irregular\:figure & = \sf area\:of\:triangle+area\:of\:rectangle\\\\ & = 4 + 6\frac23\\\\ & = 10\frac23\: \sf ft^2\end{aligned}$

A rectangular swimming pool is 40 feet long and 20 feet wide. The pool is bordered by square tiles that are x feet in length sur

olga2289 [7]

Answer:

(40 + 2x)feet

Step-by-step explanation:

see attachment for the figure.

Let 'L' represents the length of the rectangular swimming pool i.e 40ft wide.

and pool is bordered by square tiles that are x feet in length surrounding the pool

therefore,

In order to find the longest side of the pool and the tile border, take the sum of length of the swimming pool i.e 40 adding two times the wide of the square tiles

(40+2x)feet.

Is the following number rational or irrational? -3+π

enyata [817]

Answer:

B, irrational

Step-by-step explanation:

We know that π is irrational, since it can not be written as a division between natural numbers (a sub class of Real numbers called N), it's value is 3,1415(a whole bunch of decimals after this)

If you remove the decimal part of π by subtracting the integer part of it, that is the number 3. the result will still being and irrational number

Since π= 3(the rational part) +0,1415... (the irrational part)

The resut of π-=3= 0,1415...
