The volume of a large tank is 210 ft3. It is 6 2/3 ft wide and 2 4/5ft high. What is the length of the tank?
Multiply the width by the height:
6 2/3 x 2 4/5 = 18 2/3 square feet.
Now divide the volume by that number:
210 / 18 2/3 = 11 1/4
The length of the tank is 11 1/4 feet
Answer: not sure

Suppose you invest money in two accounts. One of the accounts pays 4% interest annually, and
the other account pays 5% interest annually. You have $ 2000 more invested in the account paying
4% than in the account paying 5%. How much do you have invested in the account paying 4% if
you earn $ 670 interest in a year?
Answer:
$16,750
Step-by-step explanation:
It took a lot of plugging in and guessing
The formula used was 16750(1+.04)^1
That equaled 17420
17420-16750 is 670

Determina el perimetro de las figuras geometricas que forman la rayuela
Perimetro: L=50 cm
Expresión:
Sustitucion:
P=_______/
La figura es un cuadrado y cada lado mide 50 cm
Answer:
2000cm
Step-by-step explanation:
Rayuela es un juego jugado por niños que se compone de 10 cuadrados.
Se nos da a partir de la pregunta anterior, la longitud del lado de un cuadrado = 50 cm
La fórmula para el perímetro de un cuadrado es 4a
Donde a = longitud del lado
El perímetro de 1 cuadrado =
4 × 50 cm
= 200cm
El perímetro de los cuadrados totales en la rayuela.
1 cuadrado = 200 cm
10 cuadrados = x
Multiplicar cruzada
x = 10 × 200 cm
x = 2000 cm
Por lo tanto, el perímetro de las figuras geométricas de una rayuela = 2000cm.

Answer:
448.25(2dp)
Step-by-step explanation:
1. Find the are of the entire rectangle:
length x breadth = 38 x 28 = 1064mm^2
2. Find the area of one semicircle
([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2
3. Multiply the area by 2
307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]
4. Subtract the area of the 2 semicircles from the area rectangle
1064-615.75 = 448.25 (2dp)
Hope this helps
