$Multiply\ 1\frac{2}{7}\ times\ pennies\ in\ jar\\\\
 1\frac{2}{7}*133=\frac{9}{7}*133=\frac{1197}{7}=171\\\\
In\ the\ bigger\ jar\ there\ are\ 171\ pennies.$

Remove all perfect squares from inside the square root. Assume b is positive

Tanya [424]

Answer:

4b $\sqrt{5}$

Step-by-step explanation:

Factor 80 $b^{2}$ .

80 $b^{2}$ = 4 * 4 * 5 * b * b

Since there are two 4s and bs, they can be taken out of the square. (Because if you put a square root over 4 squared or b squared, you would get 4 or b.)

Now you are left with 4b $\sqrt{5}$ .

What is another way to write the equation 7/8 x+ 3/4 = -6

Dmitry_Shevchenko [17]

Answer:

1) 7(x/8) + 3/4 = -6

Step-by-step explanation:

The term (7/8)x can be written as 7(x/8).

_____

The associative and commutative properties of multiplication let you put the factors (7)(1/8)(x) in any order or grouping you like.

Here, instead of (7·1/8)·x, the question is offering the rewrite 7(1/8·x), a straightforward application of the associative property.

Find the base of a parallelogram with a slant height of 7cm and an perimeter of 63 cm2

vlada-n [284]

Base of parallelogram b = 24.5 cm

Step-by-step explanation:

We are given:

Perimeter =P= 63 cm^2

Slant Height =a= 7 cm

Base of Parallelogram =b= ?

The formula used is:

$Perimeter = 2(a+b)$

where a is height and b is base

Putting values:

$Perimeter = 2(a+b)\\63=2(7+b)\\63=14+2b\\2b=63-14\\2b=49\\b=\frac{49}{2}\\b=24.5$

So, Base of parallelogram b = 24.5 cm
