Answer:
$2 will be your answer
Step-by-step explanation:
If u start with the 85, then add 73 it will add up to $1.58 meaning that since it is above $1.49 you will round up to $2
And both of them indivisually will equal $1 each rounded up
Answer:
A. = 20 in²
B. = 45 ft²
C. = 29.5 ft²
D. = 36 ft²
E. = 28 ft²
Step-by-step explanation:
A. Formula = A = (h_b b)/2 = base 10 ft height_b= 4ft = 20 ft²
B. We have a rectagnle and a triangle: Formula: A = lw
= A = 30 ft² and now the triangle with the same formula as above: A = 15 ft²
30 ft²+15 ft² = 45 ft²
C. we have 2 rectagnle and a triangle: First the small recangle: A= lw = A = 1ft x 2ft = 2ft²
Second rectangle: 5 ft x 4 ft = 20 ft²
Right angeled triangle Formula: (ab)/2 = 3 ft x 5 ft = 7.5 ft²
Add it all together: 2ft²+20ft²+7.5ft² = 29.5 ft²
D. is a rectangle and a triangle: 8 ft x 3 ft = 24ft²
the triangle 8 ft x 2ft = 12 ft²; add 24 ft²+12 ft² = 36ft²
E. is a right-angled triangle (see fromula above) = (14 ft x 4 ft)/2 = 28ft²
Answer:
a. 32,2°C
b. 131 °F
c. -28,9°C
Step-by-step explanation:
We must consider the following formula:
(x-32) × 5/9 = y , where x= temperature in °F an y= temperature in °C
Then,
a) In the formula we replace x=90° F, and we have: y = (90-32)× 5/9 = 32,2 °C
b) In the formula we replace y=55° C, and we have: 55 = (x-32)× 5/9 ⇒ 55×9/5 =x-32 ⇒ x=(55×9/5)+32 = 131 °F
c) In the formula we replace y= -20° C and we have: -20 = (x-32)× 5/9 = -4°F
Hey there! I'm happy to help!
We have the sum of x and 3.
x+3
One-sixth of that.
1/6(x+3)
Minus the product of 9 and p
1/6(x+3)-9p
Have a wonderful day! :D
When adding two negatives, it is the same as subtracting a positive from a negative.
-3 - 6
Your answer would be -9.
I hope this helps!
