1/4a + 1/3a +8 =22

1st step add like terms:

1/4a +1/3a = 3/12a +4/12a = 7/12a

7/12a +8 =22

2nd step subtract 8 from each side:

7/12a = 14

3rd step divide both sides by 7/12 to get a:

a = 14 / 7/12

a = 24

Robert is traveling to Mexico for a family vacation. He is bringing 625 U.S. dollars with him. Robert needs to exchange his mone
Evgesh-ka [11]

Robert should get D. 8281.25 pesos in exchange.

Explanation:

  • Robert is bringing 625 U.S. dollars with him to Mexico. He needs to exchange the money he has with him to Mexico's currency i.e. from U.S. dollars to Mexican pesos.
  • The exchange rate is 13.25 Mexican pesos for each U.S. dollar. So                               1 U.S. dollar = 13.25 Mexican pesos.
  • So to calculate how much 625 U.S. dollars is in pesos we multiply 625 with the exchange rate i.e. 13.25 pesos                                                        625 U.S dollars = 625 × 13.25 = 8281.25 Mexican pesos.

The rubber track for a toy digger goes around four circular wheels of diameter 8 cm, as shown. (b) Calculate the length of the r
Alika [10]

Answer:

73.1 cm

Step-by-step explanation:

In the drawing, the rubber track is in black and the wheels are in light gray.

As we can see in the figure, the rubber track will have a length of two halfs of a circunference of radius 8 cm plus six diameters of 8 cm. So the total length is:

Length of rubber track = pi * 8 + 6 * 8 = 25.13 + 48 = 73.133 cm

Rounding to one decimal place, we have that the length is 73.1 cm

1- Caleb's family room has the dimensions shown. He needs to find the area of the room so that he knows how much carpet to buy.
Rina8888 [55]

Answer: 20\frac{11}{32}\ sq\ yd


Step-by-step explanation:

Given: The width of the room =3\frac{7}{8}\ yd=\frac{31}{8}\ yd

The length of the room =1\frac{5}{4}\ yd=\frac{21}{4}\ yd

The area of the rectangular room= length \times width

⇒The area of the rectangular room= \frac{21}{4}\times\frac{31}{8}\ sq\ yd

⇒The area of the rectangular room= \frac{651}{32}\ sq\ yd

⇒The area of the rectangular room= 20\frac{11}{32}\ sq\ yd
