Answer:

9Kg, 18Kg and 63 Kg

Step-by-step explanation:

Sum the parts of the ratio, 1 + 2 + 7 = 10 parts

Divide the weight of sand by 10 to find the value of one part of the ratio

90 Kg ÷ 10 = 9 Kg ← value of 1 part of the ratio, thus

2 parts = 2 × 9 Kg = 18 Kg

7 parts = 7 × 9 Kg = 63 Kg

Thus the weights of each bag are 9 Kg, 18 Kg and 63 Kg

AleksAgata [21]

Answer:

Population of monkeys after 2 years = 3200

Step-by-step explanation:

Total number of monkeys at the start = 2975

Increase ratio of monkey population one year = $8:7$

∴ New population of monkeys after 1 year= $Total\ population \times Increase\ ratio = 2975\times \frac{8}{7} =3400$

Decrease ratio the next year = $16:17$

∴ Population of monkeys after 2 years= $New\ population \times Decrease\ ratio = 3400\times \frac{16}{17} =3200$

The area of a square is given by the expression square inches. Find an expression that represents the length of one side of the

Verizon [17]

Answer:

A. x-6

Step-by-step explanation:

The area of a square is given by the expression $x^2-12x+36$ square inches. Now we need to find an expression that represents the length of one side of the square, in inches. To do that we need to factor $x^2-12x+36$ .

$x^2-12x+36$

$=x^2-6x-6x+36$

$=x(x-6)-6(x-6)$

$=(x-6)(x-6)$

$=(x-6)^2$

Since area of square is given by (side)^2

Hence one side of square is (x-6).

So choice A. x-6 is correct.
