dusya [7]

So he started with 3/4 lb and ended up with 2/3 of that so 2/3 of 3/4

'of' can be roughly translated as multiply

so 2/3 times 3/4 =6/12=1/2 lb left

or you know that there are 3 out of 4 parts pound left so 2 out of 3 parts of nuts is = 2/4 or 1/2 lb

Julia collects colored beads for craft projects. Of julia's beads, 4/9 are silver, 1/5 are, gold and 1/4 are blue. The rest of t

klemol [59]

Answer:

19 red beads

Step-by-step explanation:

We first need to find a common denominator of 4/9, 1/5 and 1/4.

The common denominator is 180. Like in an expression, what we do to one side we have to do to the other.

Silver - 180/9 = 20 ; 20*4 = 80 so there are roughly 80 sliver beads.

Gold - 180/5 = 36 ; 36*1 = 36 so there are roughly 36 gold beads.

Blue - 180/4 = 45 ; 45*1 = 45 so there are roughly 56 blue beads.

180 - (silver+gold+blue) = red beads

180-161 = 19 red beads b/c ----->

80+36+45+19 = 180

What is the messure of angle 4

polet [3.4K]

Answer:

m∠4 = 40°

Step-by-step explanation:

Using the vertical angle theorem we can find that...

m∠6 ≅ m∠7

$11x+8=12x-4 \\ \\ x=12$

$11(12)+8 \\ 132+8 \\ 140$

Using this, we know that angle 6 and 8 are supplementary so...

m∠6 + m∠8 = 180°

140° + m∠8 = 180°

m∠8 = 40°

Then, we can use the corresponding angle theorem to find that...

m∠8 ≅ m∠4

m∠4 = 40°

CHALLENGE PROBLEM Danny's Department Store advertises savings of

Oksanka [162]

Discount are used to reduce the costs of items

The percent paid to determine the advertisement is incorrect

<h3>How to determine the correct percentage</h3>

The initial prices are given as: $44.00 to $152.00

And the discount is: 45% to 51%

At a discount of 45%, the price of the items would be:

$Price = \$44.00 * (1 - 45\%)$

$Price = \$24.2$

$Price_2 = \$152.00 * (1 - 45\%)$

$Price_2 = \$83.6$

At a discount of 51%, the price of the items would be:

$Price = \$44.00 * (1 - 51\%)$

$Price = \$21.56$

$Price_2 = \$152.00 * (1 - 51\%)$

$Price_2 = \$74.48$

The calculates prices show that the percent paid to determine the advertisement is incorrect
