Answer: It will take 175 seconds

Step-by-step explanation:

Let us try to take out the important information in the question:-

*** The toaster takes 35 seconds to make 4 slices of toast.

*** It takes 70 seconds to make 8 slices of toast

*** It also takes 105 seconds to make 12 slices.

*** We are required to calculate how long it may probably take the toaster to make 20 slices.

Since it takes the toaster 35 seconds to make 4 slices of toast and 70 seconds to make 8 slices, we can compare and predict the amount of time a certain number of slices can possibly be made:-

4 slices were made in 35 seconds, 8 slices were made in 70 seconds and 12 slices were made in 105 seconds.

A critical examination reveals that an average of 4 slices was processed or made in about 35 seconds. For every 35 more seconds, the toaster was able to make 4 more slices. We'll then calculate the time it takes the toaster to make 1 slice:

4 slices ---------- 35 seconds

1 slice ----------- ? seconds

1/4 × 35

= 35/4 seconds

Now, if 1 slice will be made in 35/4 seconds,

20 slices will be made in:

1 slice --------- 35/4 seconds

20 slices ------ ? seconds

(20/1) × 35/4

= 175 seconds

It will take the toaster about 175 seconds to make 20 slices.

Pavel [41]

Answer:

Step-by-step explanation:

Just use this formula when you have such type of problems:

N = N° (1 + %)^t

Where N = final amount

           N°= initial amount

           t = peroid of time

Now let's solve:

N = 1000(1 + 0.03)^30

N = 2427.26

Help. only questions 3 & 4 .
Maksim231197 [3]

I'm doing 3

     For 3, using a table is very similar to a double number because the numbers are matching up in both ways.

         On the bottom of a double number line we have like, for example,-- the bottom of the double number line would have batches. And its 1, 2, 3 ,4 , etc.

         And on a table, it would be the same, the numbers on both diagrams have the same methods, have same way of lining things up but they're just drawn differently.

                Hope this helped!

Two sides of an obtuse triangle measure 9 inches and 14 inches. The length of longest side is unknown. What is the smallest poss
julia-pushkina [17]

Answer:

17 inches

Step-by-step explanation:

An obtuse triangle is the triangle in which one of the side is the longest. It contains an obtuse angle and the longest side is the side that is opposite to the vertex of the obtuse angle.

Let the three sides of the obtuse triangle be a, b and c respectively with c as the longest side. Let a = 9 inches and b = 14 inches.

Now we know that for an obtuse triangle,

$c^2 > a^2 +b^2$

$c^2 > (9)^2 +(14)^2$

$c^2 > 81 +196$

$c^2 > 277$

c > 16.64

Therefore the smallest possible whole number is 17 inches.
