At a school number of boys : number of girls = 11 : 9
aliya0001 [1]
Ok, so 11:9
11-9 = 2
which means that 124= 2:1
124/2 = 62
so 62:0
now 11 x 62= 682
9 x 62= 558

so the ratio is 682:558
now 682 + 558 = 1,240
There are 1,240 total students in the school. 682 boys and 558 girls

Ship Co. produces storage crates that require 1.2 meters of material at $.85 per meter and 01 direct labor hours at $15.00 per h
Vesna [10]

Answer:

$3.42

Step-by-step explanation:

Meters of material required = 1.2 meters

Cost per meter of material = $0.85

Direct labor hours = 0.1

Cost of direct labor per hour = $15

Overhead rate = $9 per direct labor hour

Standard cost per unit of product :

(Direct material cost per unit + direct labor cost per unit + overhead cost per unit)

Direct material cost per unit :

Material needed × cost per meter = (1.2 × $0.85) = $1.02

Direct labor cost per unit :

Direct labor hour × cost per hour = ( 0.1 × $15) = $1.5

Overhead cost:

0.1 * $9 = $0.9

Standard cost :

($1.02 + $1.5 + $0.9) = $3.42

Name the polynomial -2x^4-x^3*8x^2-12 by degree
Murrr4er [49]

Answer:

see below

Step-by-step explanation:

-2x^4-x^3+8x^2-12

First list by highest power to lowest power

The highest power is x^4 so this is a 4th degree polynomial or a quartic polynomial

If you really mean the multiply sign

-2x^4-x^3*8x^2-12

-2x^4 - 8x^5 -12

-8x^5 -2x^4 -12

This would be a 5th degree or quintic
