Answer:

24 hours.

Step-by-step explanation:

We will solve this problem by unitary method.

∵ Time taken to type 6 memos = 3 hours

∴ Time taken to type 1 memos = $\frac{3}{6}$ hours

∴ Time take to type 48 memos = $\frac{3}{6}$ × 48

= $\frac{1}{2}$ × 48

= 24 hours

It will take 24 hours to type 48 memos.

grigory [225]

Answer:

The maximum number of turkey sandwiches Ben could have sold is 6.

Step-by-step explanation:

We are given that turkey sandwiches cost $2.50 and veggie wraps cost $3.50 at a snack stand.

Given the information, we are to find the maximum value of turkey sandwiches Ben could have sold.

$2 . 5 0 x + 3 . 5 0 y \leq 3 0$

Number of veggie wraps sold (y) = 4

2.50x + 3.50(4) < 30

2.50x + 14 < 30

- 14 -14

2.50x < 16

$x$

The maximum number of turkey sandwiches Ben could have sold is 6.

What is the lateral area of a right rectangular prism that has rectangular bases measuring 3" by 5" and a height of 6"?

Mademuasel [1]

Answer:

The answer is the option A

$96\ in^{2}$

Step-by-step explanation:

we know that

The lateral area of a right rectangular prism is equal to

$LA=P*h$

where

P is the perimeter of the base

h is the height of the prism

Find the perimeter

$P=2*(3+5)=16\ in$

$h=6\ in$

substitute in the formula

$LA=16*6=96\ in^{2}$
