Multiply the price times the number of boxes

Ok, we know that 2 boxes cost $5.16. We can divide this price by 2 to find the price of one. 5.16/2 = $2.58, so we now know that one box costs $2.58. We can multiply this by 3 to find the cost of three boxes, $7.74. Three boxes cost $7.74

Two welders worked a total of 46 h on a project. One welder made $34/h, while the other made $39/h. If the gross earnings of the
Ratling [72]

Answer:

25 and 21 hours respectively

Step-by-step explanation:

Let the number of hours worked by each welder be x and y respectively.

They worked a total of 46 hours. This means :

x + y = 46 hours.......(I)

Now, given their hourly charges, since we have the total amount of money realized, we can make an equation out of it. This means:

34x + 39y = 1669........(ii)

We then solve both simultaneously. From I, x = 46 -y

We can substitute this into ii

34(46 -y) + 39y = 1669

1564 -34y + 39y = 1669

5y = 1669 - 1564

5y = 105

y = 105/5 = 21

x = 46 - y

x = 46 - 21 = 25 hours

The numbers of hours worked by the welders are 25 and 21 respectively

2) The triangles are similar. Find the similarity ratio of the first triangle to the 1 point
USPshnik [31]

Given:

Triangles FRI and DAY are similar.

To find:

Similarity ratio

Solution:

<em>If two triangles are similar then the corresponding angles are congruent and the corresponding sides are in proportion.</em>

Here, FR and DA are corresponding sides.

$\Rightarrow \frac{FR}{DA} =\frac{4}{6}

Cancel the common factors of 4 and 6, we get

$\Rightarrow \frac{FR}{DA} =\frac{2}{3}

⇒ FR : DA = 2 : 3

⇒ ΔFRI : ΔDAY = 2 : 3

Similarity ratio of the first triangle to the second triangle is 2 : 3.
