Answer:

Find the unit rate:

3,000 pesos / 270 dollars = 11.11 <u><em>pesos</em></u> for one dollar (answer to your second question)

If he has 100 pesos you divide that by 11.11 pesos since that equals one dollar, 100/11.11 = 9 dollars (answer to your first question)

Answer:

9 American dollars

Step by step:

To find the amount he will receive when he exchanges the pesos for dollars, you can use a rule of three using the information provided:

1 American Dollar is 3000/270 = 300/27 = 100/9 pesos.

270 dollars   →  3,000 Mexican pesos

       x           ←  100 Mexican pesos

x=(270*100)/3,000=9 dollars

According to this, the answer is that he will receive 9 dollars.

Find the area of a rectangle with side lengths 5/4 feet and 5/3 feet
devlian [24]

Answer:

25/12 square feet

Step-by-step explanation:

The area of a rectangle can be found using the formula A=l*w. Here l = 5/4 and w=5/3. Substitute the values into the formulas.

A=l*w

A=(5/4)(5/3)

A=25/12 square feet

Answer:

Median is the middle of the data set. For example this data set is 4, 6, 7, 9, 10. First you take out 4 and 10. The you take out 6 and 9 to get a median of 7. But if there is an even amount of numbers like in this data set, 1, 2, 4, 5. Then you take out 1 and 5 and then find the middle point in between 2 and 4 which is 3.

WORTH 12 POINTS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! HELP ASAP
IrinaK [193]

Answer:

\large\boxed{S.A.=1,000\ u^2}

Step-by-step explanation:

We have two congruent right triangles and three rectangles.

First, calculate the length of the hypotenuse using the Pythagorean theorem:

leg^2+leg^2=hypotenuse^2

We have

leg=8,\ leg=15,\ hypotenuse=h

Substitute:

h^2=8^2+15^2\\\\h^2=64+225\\\\h^2=289\to h=\sqrt{289}\\\\h=17

The formula of an area of a right triangle:

A_t=\dfrac{(leg)(leg)}{2}

Substitute:

A_t=\dfrac{(8)(15)}{2}=(4)(15)=60

The formula of an area of a rectangle:

A=wl

w - width

l - length

Rectangle 1:

w = 15, l = 22

A_1=(15)(22)=330

Rectangle 2:

w = 17, l = 22

A_2=(17)(22)=374

Rectangle 3:

w = 8, l = 22

A_3=(8)(22)=176

The Surface Area of the triangular prism:

S.A.=2A_t+A_1+A_2+A_3

Substitute:

S.A.=2(60)+330+374+176=1,000
