Answer:
B. 30
Step-by-step explanation:
The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;
Area of a trapezium = 
(a + b)h
where: a and b represent the length of its plane sides, and h is the height.
Area of a mosaic tile = (4 + 6) 4
= 10 x 2
Area of a mosaic tile = 20 square inches.
But, Dan wants to cover a 600 square inch area.
So that the number of tiles needed = 
= 30
The number of mosaic tiles needed by Dan is 30.
2.34 im pretty sure. Hope it helps!
Since PQ is tangent to the circle, angle PQO is 90°.
Since the sum of angles of any triangle must be 180° we can say:
180-90-12=x thus:
x=78°
Answer:
$29.95
Step-by-step explanation:
All the clothing items together costs:
$12.75 + $10.20 + $12.50 = $35.45
However, since she has a coupon for $5.50 off of her purchase, you would subtract $5.50 from $35.45:
$35.45 - $5.50 = $29.95
Therefore, the total cost is $29.95
Answer:
Option A $29.46 is correct.
Step-by-step explanation:
Credit card's billing cycle = 31 days
To calculate the average daily balance we must add Carla's balance from each day in the billing cycle and divide by the number of days of the month.
( Total balance × days ) / number of days of the month
(2560 × 15) ÷31 = $1238.71
Her credit card's APR is 28% Therefore Carla charged
(1238.71 × 0.28 × 31) ÷ 365
10,752.0028 ÷ 365 = 29.4575 Rounded to $29.46
Carla charged in interest for the billing cycle is $29.46.
