Answer:
II. Longitud, L = 70 metros.
I. Ancho = 55 metros.
Step-by-step explanation:
Deje que la longitud del rectángulo sea L.
Deje que el ancho del rectángulo sea W.
Dados los siguientes datos;
Perímetro del rectángulo = 250 m
Traduciendo el problema verbal a una expresión algebraica, tenemos;
W = L - 15
Matemáticamente, el perímetro de un rectángulo viene dado por la fórmula;
P = 2 (largo + ancho)
250 = 2 (L + L - 15)
250 = 2 (2L - 15)
250 = 4L - 30
4L = 250 + 30
4L = 280
L = 280/4
Longitud, L = 70 m
Para encontrar el ancho;
W = L - 15
W = 70 - 15
Ancho = 55 m
Answer:
Volume of medication in the cup = 50.24 cubic inches
Step-by-step explanation:
Volume of the cylindrical cup = πr^2h
Radius, r = 2 inches
Height, h = 8 inches
Volume of the cylindrical cup = πr^2h
= 3.14 × 2^2 × 8
= 3.14 × 4 × 8
= 100.48
Volume of the cylindrical cup = 100.48 cubic inches
If David only fills the cup half way,
then, the volume of medication in the cup = Total volume of the cylinder / 2
= 100.48 inches / 2
= 50.24 cubic inches
volume of medication in the cup = 50.24 cubic inches
The second sentence “ stella ate 3 times as many cherries as adam” it shows that stella ate 6 cherries.
Answer:
68°
Step-by-step explanation:
Since WX and ZY are parallel, angle W and angle Z should add up to 180°
W + Z = 180°
112° + Z = 180°
Z = 68°
