Answer:
304 brass connectors.
Step-by-step explanation:
We have been given that a box filled with brass connectors weighs 5 pounds 4 ounces. The box weighs 8 ounces when empty, and each connector weighs 0.25 ounces.
Since we know that 1 pound equals to 16 ounces.Let us convert weight of box filled with brass connectors from pounds to ounces.
Now we will find weight of brass connectors by subtracting weight of empty box from weight of filled box.
Let us divide 76 by 0.25 to find number of brass connectors in the box.
Therefore, there are 304 connectors in the box.
Jayla payed $36.90 i got this because i multiplied 3 times 15 and got 45 then i did .18 times 45 which is 8.1 (8.1 is how much will be taken off) and then i subtracted 45-8.1 and got $36.90
Answer:
x = 2
Step-by-step explanation:
Bases are equal. So, compare powers
2x - 1 = 3
Add 1 to both sides,
2x = 3+1
2x = 4
Divide both sides by 2
x = 4/2
x = 2
Answer:
12 inches
Step-by-step explanation:
So you know that the perimeter of a picture frame (a rectangle) is 2 widths plus 2 lengths.
Let x= lengths and w= widths
From the question we already know that w=7, so we can set up an equation that says:
2x + 2w = 38
2x + 2(7) = 38
2x+14 = 38
2x +14 -14 = 38-14
2x = 24
2x/2 = 24/2
x= 12
Since x= lengths =12
the length of the frame is 12 inches.
area = pi X radius squared
so area = 3.14 x 124^2
= 3.14 x 15376 = 48,280.64 square centimeters.
