Answer:
scale factor 1.5 or 1 1/2
Step-by-step explanation:
15/2 is the same as 15÷2 and 15÷2=7.5
now we need to turn 5 into 7.5
to do that lets multiply by 5(1.5) or 5(1+0.5) (the 5 on the outside of the parenthesis means to multiply it by all on the inside)
and we get 5+2.5 or 7.5
so the scale factor is 1.5 or 1 1/2

Answer:
264 cubic meters
Step-by-step explanation:
So because it’s parallel you’re gonna have the same slope. You need to use point slope formula to find the equation of the line
y-y1=m(x-x1). Here, x1= -1 and y1=3. Your m is the slope which is parallel which means you’re gonna have the same slope. Our equation is given in y=mx+b form so our m is 2 so the parallel slope is 2. So m=2, x1=-1, y1=3
Plugging all of these in you have
y-3=2(x-(-1))
Simplifying we have
y-3=2(x+1)
Applying distributive property we have
y-3=2x+2
adding 3 to each side we get
y=2x+5
Hope this helps!!!
Frank worked 25 hours as a waiter last week.
<h2>Simultaneous equation</h2>
- Let the time spent as a waiter be x
- Leet the total time spent as a busser be y
If<u> Frank worked both jobs f</u>or a total of 36 hours, hence:
x + y = 36
x = 36 - y
Also, if he earns $12 per hour as a waiter and $10 per hour as a busser and earned a total of $410, then;
12x + 10y = 410
Substitute 1 into 2
12x + 10y = 410
12(36 - y)+ 10y = 410
432 -12y + 10y = 410
-2y = -22
y = 11
Since x = 36 - y
x = 36 - 11
x = 25
Hence frank worked 25 hours as a waiter last week.
