If a printer prints 28 copies in 1 minute how many would it print in 3 minutes and 45 seconds?

Mathematics
1 answer:
Wittaler [7]3 years ago
3 0

3minutes 45 seconds = 3 45/60 = 3.75 minutes

28 copies/ 1 minute = x copies/3.75 minutes

using cross products

28 * 3.75 = 1 * x

105 = x

We can print 105 copies in 3 3/4 minutes

Write the equation of a slope intercept form with a slope of 9 and a y-intercept of -3
Usimov [2.4K]

Answer:

y = 9x-3

Step-by-step explanation:

since the slope intercept form is in the y=mx+b form, you just have to plug in the slope for m and the y-intercept for b.

Let u = <-6, -2>, v = <-2, 3>. Find -3u + 2v.
Scrat [10]
We have the following vectors:
 u = <-6, -2>
 v = <-2, 3>
 Let's multiply each vector by its corresponding scale:
 -3u = <18, 6>
 2v = <-4, 6>
 Now we add the new vectors:
 -3u + 2v = <18, 6> + <- 4, 6>
 -3u + 2v = <(18-4), (6 + 6)>
 -3u + 2v = <14, 12>
 Answer:
 
-3u + 2v = <14, 12>

List the potential solutions to 2log x − log3 = log3 from least to greatest.
Sindrei [870]
Remember
if no base is stated, assume base 10
and
log_a(b)=c translates to a^c=b
and
log(a)+log(b)=log(ab)
and
log(a)-log(b)=log(\frac{a}{b})
and
(r)log(x)=log(x^r)

so

minus log3 from both sides

2log(x)-2log(3)=0
translate
log(x^2)-log(3^2)=0
translate
log(\frac{x^2}{9})=0
translate
10^0=\frac{x^2}{9}
1=\frac{x^2}{9}
times both side by 9
9=x²
+/-3=x



x=-3 or 3
