Answer:
X= Gracie
X+7.2=Hilda
X+7.2-11.4=Janell
(X+X+X+7.2+7.2-11.4)÷3=62.6
(3x+3)÷3=62.6
3X+3=187.8 (I arrive at 187.8 because I multiple 62.6 by 3)
3X=187.8-3
3X=184.8
3X/3=184.8/3
X=61.6
Step-by-step explanation:
GRACIE X=61.6
Hilda X+7.2=61.6+7.2=68.8
Janell X+7.2-11.4=61.6+7.2-11.4= 57.4
The dimension of the rectangular box is 60cm x 45cm x 32cm. The dimension of the wood used has the thickness of 2.5 cm all around the rectangular box. In order to get the volume of the wood, subtract each side of the rectangular box by 2.5.
Volume = 57.5 cm x 52.5cm x 29.5cm
Volume = 89053.1252 cm^3
Answer:
D. 0.857
Step-by-step explanation:
The coefficient of determination, R-squared, is simply the square of the correlation coefficient;
R-squared = r^2
R-squared = 0.926^2
R-squared = 0.857
Therefore, the coefficient of determination is 0.857.
Answer:
Marco earned $2.25.
Step-by-step explanation:
1. If Marco sold 12 cups of lemonade for 3$, we would divide 12 cups and how much he earned from the 12 cups (3$). 12/3 = 4
2. By the end of the day, Marco earned $9. So, 4 cups = 1$. To break it down, 1$ = 100 cents and 100 cents divided by 4 is 25 cents. Cups to Cost. ( 4 : 1 ) and/or ( 1 : 0.25 )
3. 8 cups = 2$ plus 1 cup (0.25) = 2.25.
