Answer:
the weight of each marble is 2.55 grams
Answer:
x≤1
Step-by-step explanation:
7≥3x+4
Intercambie los lados para que todos los términos de las variables estén en el lado izquierdo. Esto cambia la dirección de la señal.
3x+4≤7
Resta 4 en los dos lados.
3x≤7−4
Resta 4 de 7 para obtener 3.
3x≤3
Divide los dos lados por 3. Dado que 3 es >0, la dirección de desigualdad sigue siendo la misma.
x≤
3
3
Divide 3 entre 3 para obtener 1.
x≤1
Answer:
40 square units
Step-by-step explanation:
The surface area is given by
LA = 2(wh+lh)
where h is the height l is the length and w is the width
We do not include the top or bottom
We know l=6 w=4 and h=2
LA = 2 ( 4*2 + 6*2)
lA = 2( 8+12)
= 2 (20)
= 40
Answer:
C
Step-by-step explanation:
The amount Adam invested in a six years CD was $12,000 was 7.1%
Adam made a withdrawal of $2500 early. The early withdrawal was worth eighteen months of interest on the amount withdrawn.
Monthly interest = 7.1% / 12
= 0.59%
The interest for 18 months will be
(7.1% /12)18
= 10.65%
The penalty for withdrawing early was 18 months worth the interest on the amount withdrawn
= 2500 * 10.65%
= 266.25
This means Adam needs to pay a penalty of $266.25 for withdrawing early
