1) Asma works for 32 hours in a week and is paid £15.20 for each hour worked.

1 answer:

6 0

Asma works for 32 hr and each hour she receives £15.20, therefore, you could multiply 32 x 15.20= £486.4, which is the total amount she gets. And for James, you could multiply 30 x 11.50= £345. To find the difference in their weekly pay, we should subtract 486.4-345= £141.4.

In the function f(x)=5(x^2-4+___)+15, what number belongs in the blank to complete the square?

Maurinko [17]

Answer:

2² = 4

Step-by-step explanation:

$\text{Use}\\(a-b)^2=a^2-2ab+b^2\\\\f(x)=5(x^2-4x+\underline{\ \ \ })+15\\\\x^2-4x\\\\x^2-2(x)(2)\\\\x^2-2(x)(2)+2^2=x^2-4x+4\\\\\text{Therefore}\\\\f(x)=5(x^2-4x+4)+15=5(x-2)^2+15$

3x+2y=11 y=5x-1 SUBSTITUTION WORTH 10 POINTS

cupoosta [38]

X=1 and y=4. first I did
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1
again X=1 AND Y=4
Hope this helped

OMGGGGGGG PLSSS HELP ME WITH THIS QUESTION, IM SUPER STUCK PLS PLS PLS ITS DUE VERY SOON!!!! EXPLAIN PLSSS, WILL MARK THE BEST A

siniylev [52]

It’s H. You have to set up an equation: y=10x-11. -11 is the starting value, so you put it at the end. You add ten each time, so you put 10x. Just plug in 100 for x, and you’ll get 989

A boat traveled 100 miles downstream and back the trip downstream took five hours the trip back to 10 hours what is the speed of

salantis [7]

Answer:

boat: 15 mph
current: 5 mph

Step-by-step explanation:

The relation between time, speed, and distance is ...

speed = distance/time

The speed downstream is ...

downstream speed = (100 mi)/(5 h) = 20 mi/h

The speed upstream is ...

upstream speed = (100 mi)/(10 h) = 10 mi/h

The boat's speed in still water is the average of these:

boat speed = ((downstream speed) + (upstream speed))/2 = (20 +10)/2 mi/h

boat speed = 15 mi/h

The speed of the current is the difference between the travel speed and the boat speed:

current speed = downstream speed - boat speed

= (20 mi/h) - (15 mi/h)

current speed = 5 mi/h
