Find the highest common factor (H.C.F) OF 168 and 252.

1 answer:

3 0

Let's first write all the factors of 168 and 252.

168 - 1,2,3,4,6,7,8,12,14,21,24,28,42,56,84,168
252 - 1,2,3,4,6,7,9,12,14,18,21,28,36,42,63,84,126,252

84 is the GCF because 84 is greatest common factor of 168 and 252.

So, 84 is the GCF

Hope this helps.. :)

Abdul's gas tank is 1/5 full. After he buys 7 gallons of gas, it is 7/10 full. How many gallons can Abdul's tank hold?

eduard

Answer: 14 gallons

Step-by-step explanation:

Let's call the total gallons of gas Abdul's tank can hold x.

Then, based on the information given in the problem, you can write the following expression:

$\frac{1}{5}x+7=\frac{7}{10}x$

Therefore, when you solve for x, you obtain the following result:

$\frac{1}{5}x+7=\frac{7}{10}x\\\\\frac{1}{5}x-\frac{7}{10}x=-7\\\\-\frac{1}{2}x=-7\\\\-x=(-7)(2)\\x=14$

A braid was bought to put around a blanket that measures 23 inches by 24 inches. At $0.60 per yard how much was paid for the bra

mojhsa [17]

To do this you need 94 inches of braid.

94 inches = ? yards

1 inch = 0.0277778 yard

94 × 0.0277778 = 2.6111132.

Since you can only pay for a full yard you would buy 3 yards which would cost:-

$0.60 × 3 = $1.80.

So for this you would need 3 yards which would cost $1.80.

Hope I helped:P

Factor 1 and 2. You do NOT need to show or explain steps for 1-2.

kogti [31]

Answer:

Step-by-step explanation:

x² + 9x + 18 = x² + 6x + 3x + 18

= x(x + 6) + 3(x + 6)

= (x + 3)(x + 6)

x² + 16x + 63 = x² + 9x + 7x + 63

= x(x + 9) + 7( x+ 9)

= (x + 7)(x + 9)

y² + 13y + 36 = y²+ 9y + 4y + 36

= y(y + 9) + 4(y + 9)

= (y + 4)(y + 9)

(a). Factored form of the expression (y² + 13y + 36) is (y + 4)(y + 9).

Therefore, Lyndsey's answer is wrong.

(b). Factors are (y + 4) and (y + 9).

(c). Factored form of the expression should be (y + 4)(y + 9) instead of Lindsey's answer (y + 6)(y + 6).

A population of 422,000 increases by 12% each year. What is the approximate population after 5 years?

Zarrin [17]

Here are formulas we choose from
Increasing: y = a (1 + r)x Decreasing: y = a(1 - r)x

we want increasing

422000(1+.12)^5
743,708 (you don't want the decimals because you can't divide a human...)
