Perform the indicated operation 2 3/8 x 5 3/4

Answers

Hello!

Change each mixed number to an improper fraction to make it easier

2 3/8 = 19/8

5 3/4 = 23/4

Now, multiply

19/8 × 23/4 = 437/32 = 13 21/32

Answer ⇒ 13 21/32

2 $(3)/(8)$ = $(2(8)+3)/(8) = (19)/(8)$
5 $(3)/(4) = (5(4)+3)/(4) = (23)/(4)$

$(19)/(8)$ ÷ $(23)/(4)$
= $(19)/(8)$ x $(4)/(23)$
= $(19(4))/(8(23))$
= $(19)/(2(23))$
= $(19)/(46)$

The following 3-D object is composed of identical cubes. The volume of the 3-D object is 56cm cubed. The surface area of the 3-D object is
a) 30cm squared
b) 60cm squared
c) 120cm squared
d) 144cm squared

Answers

There are 7 equal cubes by inspection that make up the shape.

Each cube has a volume of: (56 cm^3)/7 = 8 cm^3

To find side dimension of cube (knowing a cube is the 3D extrusion of a square meaning all sides are equal:

s = (side dimension) = (8 cm^3)^(1/3) = 2 cm

Also by inspection, there are 5 exposed faces on 6 of the 7 cubes. To find the total surface area, multiply number of exposed faces per cube by the surface area of a single face:

S.A. = 5(6)(2*2) = 120 cm^2

The correct answer is C). 120cm squared

the drama club was selling tickets to their play for $7 per adult ticket and $5 per child ticket and made $350 . They sold 10 more adult tickets than child tickets . Write system of equations that could be used to find the number of adult (A) tickets and child (C) tickets that were sold

Answers

Answer:

7a +5c = 350
a - c = 10

Step-by-step explanation:

It is convenient to use the variables "a" and "c" for the number of adult tickets and child tickets, respectively. Two equations using these two variables can be written based on the given information:

7a +5c = 350 . . . . total revenue from ticket sales

a - c = 10 . . . . . . . . 10 more adult tickets were sold

_____

Comment on the question

The solution to these equations is a=33 1/3; c=23 1/3. There is no integer solution. In real-world terms, the given relations cannot exist.

Laketown had 215 inches of snowfall last year, but only 155 inches this year. What was the percent decrease in snowfall for Laketown to the nearest percent? A. 28% B. 39% C. 72% D. 139%I think A

Answers

Okay, so FIRST you would subtract 215 - 155, which is 60, and THEN divide it by 215, so 60 divided by 215 = 0.27, and rounded that is 0.28, then you move the decimal two places to the right to make it a percentage so your answer would be A., 28%
I hope I helped! =D

*lets do this step by step*

1st. subtract
215 - 155 = 60

2nd. divide
60 ÷ 215 = 0.2790697674

3rd. we round
0.2790697674 = 0.28

answer? A.) 0.28

hope this helps:)
