I'll teach and give you the answer for you problem (5 2/7 −1 1/2 )∙(1− 14/53 )
Convert mixed numbers to improper fractions 5 2/7 = 37/7:
(37/7-1 1/2) * (1- 14/53
Convert mixed numbers to improper fractions 1 1/2 = 3/2:
(37/7-3/2) * (1- 14/53
Join 37/7-3/2 = 53/14
53/14(-14/53+1)
Join 1-14/53 = 39/53
53/14 * 39/53
Cross-Cancel 53:
39/14
Your Answer As A Improper Fraction---> 39/14
Your Answer As A Mixed Number---> 2 11/14
plz mark me as brainliest :)
Answer:
You should also try solving it yourself to make sure I did not make any mistake.
Step-by-step explanation:
We already know the slope so, so far the equation should look like this.
Now we just need to insert the point into the equation. So point (7,9) 7 should replace the x and 9 will replace the y. It will look like this:
when you solve this equation you'll get b
So the equation is
Answer:
Linear equations are used to calculate measurements for both solids and liquids. An electrical engineer, for example, uses linear equations to solve problems involving voltage, current and resistance.
Step-by-step explanation:
Answer:
1 cm = 3 feet.
Step-by-step explanation:
Divide 15 by 5 to get 3; on the blueprint, every centimeter represents 3 feet.
Answer:
$153
Step-by-step explanation:
To find the total cost, we have to calculate the area of one bead, then all of them:
Area of one bead = pi x r^2 = 3.14 x 0.5^2 = 3.14 x 0.25 = 0.765cm^2
Area of 20 beads = 0.765 x 20 = 15.3cm^2
Now, we are able to calculate the ultimate cost of coating:
If the cost is $10 per cm^2, then we have to find how much it costs to coat 15.3 cm^2.
15.3 x 10 = $153.
Hope this helps
