g A jacket regularly sells for $135.00. The sale price is $60.75. Find the percent decrease of the sale price from the regular p
Alenkasestr [34]

Answer:

55%

the percent decrease of the sale price from the regular price is 55%

Step-by-step explanation:

Percentage decrease is the percentage change in the sales price (regular and new)

Percentage decrease %∆P = ∆P/Pr × 100%

∆P = change in sales price = $135 - $60.75

Pr = regular price = $135

Substituting the values;

%∆P = (135-60.75)/135 × 100%

%∆P = 55%

the percent decrease of the sale price from the regular price is 55%

Simplify.<br> 10u -4u<br> Please help
vovikov84 [41]

Answer:

6u

Step-by-step explanation:

The two terms 10u and 4u are like terms because they both carry the same variable (u) with the same degree (1). So, we can just subtract them as if they were normal numbers 10 - 4:

10u - 4u = 6u

Thus, the answer is 6u.

Hope this helps!

Answer:

80 degrees

Step-by-step explanation:

We can use the Central Angle Theorum, which states that if the vertex of the angle is the center of the circle, then the arc is the same measurement as the angle.

In this case, m<COB is 80 degrees, and the vertex is the center of the circle, which means that measure of arc CB is also 80 degrees
